IHRA coming to my local track PBIR, Can I run in any of the classes?
 

I'm trying to go through the rulebook to determine if I fit anywhere, I would like to run when the Nitro Jam comes to my local track at Palm Beach International, so If i fit anywhere I can become an IHRA member and get prepared since the race is in January.

I was thinking maybe I fit in the Stock Fuel Injection class 12.00-12.99, Let me know. I'm not sure how strict it is with mods/bolt-ons. I'm going to list my mods so you can perhaps help me know if I belong anywhere or not.

I haven't ran the car yet since i switched to 15 inch wheels and the light weight driveshaft but from my estimates should be in the mid 12's. Looking around 12.40-12.50 for this fall/winter. Previous best was 12.7

The car was dyno'd at 312rwhp

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

First off is Stock Fuel Injection class 12.00-12.99, this is not a reference to et, its weight break. and a fast look at your list you have Steeda Upper & Lower Control Arms, these are not allowed in Stock. I do not have my rule book handy but look under modified stock. Some of the IHRA guys will fill you in.

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

I havent got my rule book in front of me but off hand i would say that the grille, the window louvers, the cold air intake ,and the steeda control arms gotta go. And the 12.00-12.99 reference is a weight break figured by a factored hp to weight formula and adding 170 pounds for driver will give you a minimum weight.

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

holy cow weird rule not to allow louvers,grille.. They only allow stock control arms? The stock control arms are horrible lol. Bummer, it sounds like I won't be able to run any classes. That is depressing, figured I fit in somewhere.

Is their any class that the car can fit into?

perhaps modified stock or else where? My grille is just an overlay on the stock grille.. =/ and rousch louvers come on rousch's so its not like off the wall :P

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

Replacement rear upper and lower control arms are allowed in stock.
Only the uppers can be adjustable, the lowers cannot.
I do not think that IHRA would have a problem with the grill or louvers.
Even NHRA allows non Z-28 Camaros to use Z-28 trim.
Aluminum drive shaft is allowed in IHRA stock.
Pullies should be OK.
Cold air kit needs to be looked at by IHRA tech as some direct replacement units are OK.

Good luck.

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

thats good news. My control arms are both non-adjustable.

Do you think I fit more in with Stock Fuel injected or Modified stock, im trying to see who i can contact at IHRA for more info. What division is FL in IHRA?

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

so they add 170 pounds to the car's weight no matter what?

I only weigh 160.

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

Tweaker - You need a crash course in class racing. Classes are determined by horsepower to weight ratios. Each engine has a horsepower rating assigned by NHRA or IHRA. Each car would get a hp/weight factor depending on the listed shipping weight of each vehicle. This is what determines your class. (170 lbs driver weight is added to shipping weight to determine minimum racing weight. It doesn't matter how much you weigh.) You are then allowed to do certain modifications depending on your category. Stock can do so much, Super Stock even more. You then must be able to run on or below the ET index for your class. The problem is that you would probably not be able to run your index without building your car to the limit of the rules. (acceptable cam and valvetrain, blueprinting, gear ratio etc.). If they run a bracket program with the IHRA race, you'd be far better off there.

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

Dang, Sounds complicating. = { I thought in the stock class you could not change your cam and other things. = \

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

if your car is not a Roush than the louvers arent stock.

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

ill bet he'll tech in superstock ok...

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

Dont be discouraged i went through all of this a couple of years ago, once you take your bumps and bruises it is an absolute riot. Get a rule book and find some class racers and ask a LOT of questions

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

im assuming id get killed in super stock, can't you use electronics in that class? i dont have any :P

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

Super Stock allows transbrakes and air/electric shifters. No delay boxes or throttle stops. Check your Private Messages, I sent you some info that should help a lot.

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

i wrote back mike, thanks guys for all the help im learning but im still a little clueless if their is a place for me or not in one of the classes = {

hmmm

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

Sounds to me like you have a D/PS car! take the underdrive pullies off & also the cold air... car would have to weigh 3470 with you in it & the index is 13.10! or you can leave everything the way it is add a roll bar & run G/SA the same weight & the index is 12.30....

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

The 1st thing you need to do is find out where your car breaks for stock class. You find this by dividing the rated horsepower by the shipping weight. NHRA has all the factors listed on their website I could not find them on the IRHA site. I cant read the word documents on the computer I am at now but I think your car is 300hp but I have no clue the factory shipping weight. For arduement sake and easy math lets say it is 3600. 300 divide 3600 you would break at 12 lbs which would be E/FI I think again I am not super familar with IHRA rules and NHRA dropped the FI classes. I think your index will be 12.50 you have to dial atleast 12.50 if not quicker during elims to run E/FI your car would need to weigh a minium of 3770 as well If you can fit in D/FI your min weigght with driver is 3470 but your index is now 12.20 Again theese are all just my best guesses with the limited info you have given and the limited info I can pull off the internet Also listen to Alex Densenyko(sic) he is a IHRA champ and ford racer . Hope you find aclass and have agood time

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

thanks guys for all the info, ill have to get with IHRA person to i guess find out if i can meet specs or not but it sounds like I'd either fit into D/FI or E/FI depending on my weight i need to hit the scales. I have a feeling im gonna wind up being in the weight range for D/FI, but it will be rather tough since it appears the index for IHRA is 12.10 for that class and as of now i bet this winter im most likely in the 12.4 range. = [ need more power lol.

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

Your first step should be to get an IHRA rulebook, it's all there in black and white.

You'll need to know a few things about your car: current weight, engine size, type of trans...mostly normal things.

Get the rule book and look for the class your car fits in and what modifications you can legally make for the specified class.

Call them and order the book: 419-663-6666

The rule book is your Bible for class racing.

JimR

Good luck!

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

Class racing is a science. I was new to it several years ago and the best advice I have is to find someone in your hometown who has been at this for years, become his/her best friend and allow that person to be your mentor. This person will explain the rule book and classification guide for your class step by step, face to face, and work with you on your combination. You won't get all the secrets but at least you will be off and running. This is how I narrowed my learning curve. Good luck!

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

Hey send me a PM. I live in the WPB area.;)

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

good luck. Always glad to see more class racers. However, one caveat. It is very hard to be competitive with a dual purpose car. The only person I know doing it happens to live in your area. Jeremy Preston is leading the NHRA div2 points in stock with a daily driven corvette. Jeremy and his dad own Horsepower Sales, you might want to give him a shout

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

Anyone interested in Class Racing is a good thing. Buy a NHRA, and IHRA rulebook, than build the car to the rules. The NMRA also has classes you may be interested in. Keep the sport alive. Good luck.

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

thanks everyone for all the help and advice.

I'll see what I can dig up and my goal is just to run 1 event at my local track at PBIR in Jan, I don't have a trailer right now and i know all the racing will add up in cost :) But it would be fun and an experience to do 1 event for now. And I'll just do my regular bracket racing at my local track throughout the fall/winter.

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

if your only wanting to run the IHRA event and nothing else i would see what all you would have to change for the pure stock classes...which is more or less for the street legal cars you almost would have to do anything different to get your car into on of those classes....less expensisve and you prob wouldnt have to worry about anyone around there running in your class....my dad ran his 95 cobra years ago in G/PS...you would prob have to change your cold air kit but you could get a bigger mass air sensor and use your cone air filter still....not sure about the control arms but pretty much its a hopped up street car class.....that would prob be your best bet...you shouldn't have any trouble indexing eather...

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

[QUOTE=Brandon Peterson; pretty much its a hopped up street car class.....wrong wording to use !

THE PURE STOCK CLASSES ARE BASED ON WHAT STOCK ELIM. WAS DURING THE "PRE 1985 DAYS". Its a time where the cam had to check on duration, overlap, and lift. The valve spring pressures had to check per OEM spec. No bogus replacement parts, no wheelie bars, etc. Its all listed in the rule book. Reading the rule book should be your first step in preparing for class racing. The control arms would have to be changed back to OEM parts and the cold air add on would have to go. The classes are listed from 8 thru 16 lbs per rated HP in full lb breaks (8 is A, 9 is B, 10 is C, etc.) sticks and automatics run together heads up in the same wt. break. There are a few pre 1971 Jr. stock type cars in this catagory such as 57 Chevy's, etc. but it has seemed to evolved to a late model. FI computer controlled car class. The concept was a good idea but Im afraid its time has come to be obsolete for the little guys in racing. Todays stockers are more radical than my S/S Camaro was in 1978. I dont want to discourage you but be prepared to spend $$$$$$$ and LOTS of it to compete in todays stock eliminator..

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

Yeah honestly i noticed that now that i dig into it, its pretty sad their is no like Amateur type of racing now unless its just local bracket racing, its pretty sad you have to be insanely rich or sponsored up the butt.

Thanks guys for all the help i guess if i cant find a place i belong for one race ill just not race im def not taking off parts and putting on crap OEM stock parts to race. I want to go faster not slower :P

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

I wouldn't go as far as to say you have to be rich. I went to the junkyard and got a motor this past week. Put my cam in it, a set of valve springs, and went racing. $500 and some parts we had and we were in business. It is all in how much you want to spend really. It can be done cheap but most dont choose to do it cheap!

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

Don't believe it can be done cheap with my car, i believe my index would be 12.10 and im most likely in the 12.40-12.50 range id need more power to get to the index but im kinda running out of bolt-on's for this car and i don't know if any cam's on the market will meet the stock elim specs but cams are also expensive for this car too =P i need to get her weighed but 12.10 index for my car is a stretch w/ out more power (mods) or less weight. bone stock this car ran like 13.8-13.9.. its all good i just wanted to go out and have some fun we'll see what happens. :) I'll get her weighed, talk to some people from IHRA see where I would belong and if i dont really meet the index i'll see if i can by january if not i guess maybe down the road keep trying to get there =P Can i put any cam in to run stock elim, or their a certain lift or duration it has to meet?

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

Lift is the only thing checked on the cam in stock. If you run pure stock they will check lift, duration, and overlap.

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

so lift has to remain stock lift in stock elim? i dont think their are any aftermarket cam's out for my car that remain the stock lift ..


Intake Theoretical valve lift @ 0 lash -11.166 mm (0.439 in)

Exhaust Theoretical valve lift @ 0 lash -11.066 mm (0.436 in)

im seeing aftermarket cams with lifts of .492, .470 .480.. bummer man stock elim class is tough :P

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

The "STOCKER" grinds are usually custom ground and not "Off The Shelf" items or in a catalog. You have to call a company like Comp Cams and talk to Chris Pagent (speling?) and see what he can come up with for your car and engine. The other problem is the Detroit Manufacturers have stopped supplying NHRA and IHRA with duration and overlap spec. for the last several years along with spring pressure specs since the cam and spring rule was changed in 1985. The class was originally intended for the older style stockers that IHRA still has specs for such as 1949 Olds, 55-57 Chevys, 389 Pontiacs, 348 and 409 Chevys, etc.In other words it seems you would be able to use a current "stocker" grind and get away with it although they really suck as a street cam (no vacum). You should call Mike Baker (tech director) at IHRA for conformation of what Im posting on this site to be sure. Its been about 8 years since I have worked with the assoc. He's a good guy and will work with you and your combination. Danny Waters Sr.or Hank Blankenship are also good guys who would help out. Hank is the guy you would probably end up dealing with IF you had to go to tear down (yes it happens on occasion) to be certified as legal. You can also get the engine specs from them to give you what you need to know for the head C.C.'s, deck height, valve size and etc. Good luck.

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

It sounds like your car may be close to being legal for Pure Stock. D/PS has an index of 13.10 and your car would have to weigh 3470 lbs according to the NHRA HP rating of 300.

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

Tweaker, don't get discouraged, find someone running the class you want to run and ask questions, my daughter got her 2007 Mustang to run 12:25 with minimum ( legal)work, headers from Roush, 4:10 posi, Drive shaft safety hoop, 15"x 9" Bogart wheels, 9" slicks, reprogram computer(You need someone who knows how to set it up) and removal of excess weight. You must follow IHRA guide but I know once you have the right information your car will run properly. Good luck

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

im going to Private msg u!

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

you know what that may be where i belong i'll call ihra folks perhaps they'll let me run in it even though i have the louvers and grille i mean that is pretty lame if i cant because of that and my control arms are non-adjustable streetable steeda control arms nothing crazy or fancy besides that it sounds like i would be pure stock i mean my cold air intake is nothing crazy either its just a C&L plastic elbow w/ a K&N air filter on it on it. thanks ill look into it.

Can you run ET Fronts and ET streets in Pure Stock though?

omfg, another bullet in my journey... i read in the rule book it talks about only factory tint on windows in pure stock, wtf I live in florida. I have 15% tint on my side windows and rear window.. these rules are RETARDED. They need to be updated from the 1960's and update to 2009.

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

I think you need to have 2 cars. One for the street and one for class racing. Rules are rules and the tinted window deal is so the starter can SEE YOU and make sure you have your helmet on and seat belts fastened. Other classes require a window net and a full face helmet so again the starter needs to be able to look inside the car before the tree is activated. Its not about 1960 vs 2009. Also if the car runs quicker than 11.50 or is required to have a LEGAL roll bar you will also be required to have current dated (within 2 years) SFI approved 5 point harness belts. The OEM seat belts wont cut it. I have noticed that most (not all) younger guys seem to think the rules are lame or retarded and the associations should change the rules to suit them. Welcome to the real world.

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

I understand the rules I mean if you get your car tech'd and inspected when u come into the track they see if you have the proper equipment so the tint is kinda void. You can run tint at tracks on regular bracket races but i guess national type races are even more tight on rules.. Yeah eventually I'm getting a truck to be my primary vehicle when funds permit. Owell. So i guess im screwed since i have tint and all the classes require no tint! lol

Re: IHRA coming to my local track PBIR, Can I run in any of the classes?
 

Well believe it or not.....I have seen some guys come to the starting line WITHOUT a helmet even in the car. Some have tried to run with their seat belts unfastened or the window net down on cars that require a full roll cage. It does happen from time to time mostly from being in a hurry to race and not miss a round which means a DQ.. Thats why the starter needs to see that you are using the required safety equpment before ativating the tree. Just having it during teching in dosent mean much. A lot goes on in bracket racing that shouldnt happen (not saying you would do it). I see a lot of bracket cars without a fire wall between the fuel tank/cell and the driver and 5+ gals of gas plus a battery just hanging by a thread right next to the fuel cell. Thats because the tracks just want your entry fee and a lot of local so called tech people just dont care. The NHRA and IHRA tech people DO care about your safety. After 22+ years at this silly game I have seen just about anything and everything. Be safe first and enjoy. Its a great hobby.
