SST legal
 

Hey guys I am thinking of purchasing a tube chassie Mustang II to build/race in sst. Is there any reasons you guys can think of that would make that style car not leagel for the class. (Such as wheel base- the engine was moved to the rear but I think I can move it back) It's an older tube car but will recert to 8.50 with no problem. Any help would be great. Thanks Joe

Re: SST legal
 

As long a it passes NHRA tech, no issues, just remember S/St 2800lbs minimum

Re: SST legal
 

I would have to add approx 240lbs, is that a lot of weight to add?

Re: SST legal
 

In S/ST you're allowed to add up to 500 pounds but there are several legal requirements to be met (NHRA Rulebook General Regs 4.2) so you're going to have questions that downloading a rulebook will help you with. In general you want to add weight fairly close to the centerline of the car (corner weighting to achieve correct balance recommended) and also toward the rear as a traction aid. 10.90 in IHRA only requires 2600 weight min. so might be good place for you to start...

Re: SST legal
 

Thanks for the responses I was mostly worried about wheelbase requirments and things like that. will download the rules today. I love the bracket/sst/sg style racing to the grief of my friends. (heads up racers)

Re: SST legal
 

Lots of ways to add weight without it being in a box.
Like
Big batteries
Steel heads
Stock type radiator
Cheeseburgers,fries,and shakes
Lots of shakes

Re: SST legal
 

LOL.....That made me laugh this morning. Hope you have a good year. Thanks Chip !
P.S. You guys seem to have a lot more fun than those nuts running stock and S/S. I might just end up running with you guys in H/R and some Unleashed 11.0 class stuff as Im still not crazy about throttle stops. Just want to have some fun before its to late. It just makes more sense and not as expensive. Those guys over in class cars would argue over a lug nut.

Re: SST legal
 

You know the reason we run throttle stops right? We figure if we slow our cars down, then we will know what it's like to run stock and super stock. lol

Re: SST legal
 

Hey X, That's some funny stuff there...But it's true. They argue so much that they make my wife sound competent..I like droppin' in over there every now and then and stirrin' them up. And believe me, it doesn't take much. I don't know how they can stand racing together without a free for all breaking out.

Re: SST legal
 

Terry,
Billy Plague told me once " Now that you got a stocker again you can park with us". I told him I would park there but I was hangin with the .90 guys. They know how to have fun. LOL
Come on over here you will be welcomed with open arms.
Thanks
Chip

Thats some funny stuff true but funny!!

Re: SST legal
 

I've thought about running s/st, but I don't think I can run enough mph. My car runs 10.0's at 135ish. With a stop, how much mph would I kill? What do you think the average mph is for the class?

Thanks

Re: SST legal
 

Ron,
I run high nines at 136 off stop. On stop I run 10.90 2 132-134 depending on track and air.

MPH don't matter Running 10.90 does no matter how you do it.

Re: SST legal
 

Thanks Chip.
I thought the speed would come down more than a couple when taking almost a full second out.

I like to do the catching as much as possible. I know a guy that runs 10.90 at 150. I hate being caught with that much difference in mph.

I've never run with a stop or a trans brake. I guess I have a lot to learn, and spend.

Re: SST legal
 

As previosuly stated it aint about the MPH it is being able to hit the tree and run the number. I think some folks get WAY hung up on the MPH thing personally....

Re: SST legal
 

Does anybody ever try to run s/st foot braking?

Re: SST legal
 

In the last 20 years??? Doubt it. "Back in the day" when you could win by adjusting your linkage "stop" ( a bolt) it was possible. I won a divisional once that way but the car was so dialed in it made my job easy.

Re: SST legal
 

a guy from Pittsburgh raceway park drove his grandma's mustang to the track, foot braked it, flat out, put a .003 package on me, then drove out to McDonald's with his Friends to celebrate! at least thats the story i got.

Re: SST legal
 

Keith,
I think it was his mom's car. He was Footbraking with no stop. I think he SF day 1 and went 3 or 4 rds in the TOC race.
Chip

Re: SST legal
 

I won two IHRA National events in H/R in 91 foot braking , no electric shift and threaded linkage rod on 4 tenths tree. Back when they was real iron men,...
Sure miss them days......

Re: SST legal
 

I ran a couple of PTRA 7.0 class (.400 Pro Tree, deep staging ok) a couple years ago, and won the 2nd race out, footbraking my Stocker. Ok, so it was only a 2 round race, but I won! :D (Then they put the classes together in a handicapped Pro Tree bracket style deal, and made it to the semis with a broken rear!)

Bottom line, like others said, doesn't matter *how* you do it (R/T or ET), as long as you *can* do it.

Re: SST legal
 

Ron I would say looking at qualifying sheets that the average 10.90 car is around 130 to 135. Just what I have noticed over the last few years but can the guy running 150 judge me running 125 any better than I can judge him? I doubt it, he just gets to look out the front window.

Re: SST legal
 

And hang about a 1/4 of a fender on ya when he catches us......................

Re: SST legal
 

lol, thats what i was thinking

Re: SST legal
 

Thats when I dump him cause I know he is carrying 5

Re: SST legal
 

lol. that never happens, does it?????

Re: SST legal
 

Okay, help me out. What will it cost me to get in. I need a brake, a delay box and a throttle stop...right?

This is a 400 trans and a 12 bolt.

I don't have a flex plate shield, do I need one. Everything else is dated good.

Re: SST legal
 

Ron
On the flex plate shield I don't run one but I'm under 135 mph and still have stock firewall and floor.

As far as the cost, that depends on you. Just guessing I'd say about $1000. up to $1500. doing it yourself. You will want a d-box with timers for the stop. Something else is the diaper, next year they will be mandatory !

Re: SST legal
 

I had no idea about the diaper, what a PIA. How many oil downs happen in 10.90 cars? Biondo has too many boxes, Mega this and Mega that. Which one do you like? Which T-stop? The car has a Dominator on it.

Re: SST legal
 

Jamie sothers has a dedenbear disk stop complete for sale on here sounds like a good deal, i like #1 stop stuff. you cant go wrong with a mega 450, but any box with t-stop timer will do....

Re: SST legal
 

Ron, not wanting to sound critical, but I think every car out there should have a diaper. I've been unfortunate to have wrecked my car twice from getting into oil on the track. First time was my oil, from a failure of an o ring on the filter. (Diaper would have caught the oil) second time was getting into oil that someone else put onto the track. I was way more upset after the second time, because that was after they started mandating diapers but it was from a car that didn't require one. Point is, it's not always about you, think about your competators as well. It may not be your wallet that ends up paying the consequences.

Re: SST legal
 

I understand completely, you make a good point. I recently went back to a stock type filter and I have a blocked by-pass so I worry about the filter O-ring. I'm willing to run one, but they are a pain.......aren't they?
They mount to the header bolts, with straps, right? Aren't the straps in the way if you have to change plugs? Will they go on and off with a stock Nova subframe?

Re: SST legal
 

Dennis at DRE can fix ya up and there not as bad as you would think..

Re: SST legal
 

Great thread, all this info from a "is it legal" question. Well I drove to PA and brought back a tube chassis mustang II.(Detroit) My shop is super busy right now put I hope to get to it in the next couple of weeks. My fab guy wants to update the car and keep the 7.50 cert but not sure it matters for what I want to do with it though. The car was built a LONG time ago but has really good parts on it. So the next question is this: I have parts lying around the shop to build a 515 bbc should make plenty of power but I purchased a new deadenbear TS with the second linkage from a guy on here about a year ago for a 4150 style carb.(all new in box) This will hurt power but I don't think that it will matter, it should still run plenty under, but do you guys think it will be just a consistant with the smaller carb on a bigger engine.

a side note I do machine work for some pretty good S/SS guys --way tooo high strung waving temp gauges at 7:30 in morning and draining oil out to go faster. I'm looking forward to being a duck in the 90 towards the end of the season. (for a few races any way)

Thanks Joe

Re: SST legal
 

I've heard plenty about how much more consistent an under carbed engine is. You can also get 4150's that flow 1200 cfm.

Re: SST legal
 

That's what I was thinking too Chip I just throwed the anchor on him.

Re: SST legal
 

Call Dennis at DRE he can fix you whatever you need for a diaper. Reel easy to deal with.
About plugs. How often do you change the plugs?
How often do you change the oil?
What if it takes a few extra minutes.
I think diapers should be required.
I have one on the dragster and will have one on the camaro soon.

Re: SST legal
 

So says the guy running a 7 second car in SST ;)

As far as footbraking, I have won a West Coast Super Gas Association event (which in those days was a 7 or 8 round event) footbraking, and many rounds in divisional racing as well. I also won a bunch of races in an 11.90 index car with .400 tree and no deep staging (I could redlight with either good air or a tiny bump in). All of this was before the LEDs and .370 tree though, and I don't seem to react as quickly to the LEDs as the 0.030 tree difference assumes I will.
