IHRA Take on Runner Volumes
 

What is IHRA's take on cylinder head runner volumes?:confused:

Re: IHRA Take on Runner Volumes
 

As far as I can tell, it's always been the tech person's "call" based on his interpretation and that of the head tech person, apparently like in NHRA. IHRA usually follows NHRA's rules with this to minimize any problems with cross-over racers. I would guess that they would continue to do that when any new head rules come out.

Re: IHRA Take on Runner Volumes
 

So Myron, what have they(IHRA) done on the Crate motor engines about establishing runner volumes?

Re: IHRA Take on Runner Volumes
 

Woodro I'd say IHRA will make no changes. A couple years ago when the piston rules were changed up IHRA went with stock top on the piston to make the rules more simple.

STOCK

If 2 competitors are in the same class at the World Finals Tournament of Champions they will run off of a dial in.

Ha ha Ho Ho LOL Heh heh sorry....I just couldnt help myself. Yeah....who's heads are they going to set the standard with? Some of those FAST Dusters using the 360 Magnum's.? I just happen to have a couple sets of OEM untouched standard Magnums and R/T heads in my garage. I cant wait to see what they come up with..........GRIN

And Greg i applaud IHRA for that decision on piston's

Re: IHRA Take on Runner Volumes
 

XTECH man what is that suppose to mean. One thing about it there are some racers that love ratting out other racers on certain things some which are stupid. I love it when a racers starts a conversation knowing he is going to tell the tech guy everything that is said. What do you racers think about that?

Herb.....Ive been around this stuff almost as long as you are old. I NEVER ratted out anyone and never will. Ive fought long and hard years ago (about 10) about this horse s**t to no end with Len Imbrigno, Bob Lang of NHRA and IHRA people but its like talking to a stone wall. When they take the volumes from heads that have already been ported its a friggin' JOKE like most were done in S/S. . Ive also done cylinder heads for racers since 1969 and have seen it all from 22 years of tech inspection. All they need to do is use a CORRECT volume with a + tolerance from a VIRGIN head and let it go. Dont set up a spec. from one of these cars that runs 1.4O under just because the car is owned by a super star. This crap of hiding what goes on will never change until they get the rules written to where the cost of these heads and intake manifolds can become a little less expensive. When the inspectors cannot DQ a part because the way a rule is written it needs to be changed. Just my opinion and we all know what amounts to. ZIP !

Re: IHRA Take on Runner Volumes
 

Woodro,

As far as the Mopar combos, many, but not all, of the accepted crate motor heads are also used in OEM applications that NHRA and IHRA should have specs for, including runner volumes for SS. So IHRA should use whatever Stock volumes NHRA comes up with. I don't know what GM or Ford crate motor heads can also be found in OEM production cars. I run the 360/300hp Commando (shaft mounted rockers) which IHRA allows any production 340 or 360 head which was originally available with 1.88" intakes. The original crate motors came with 308 production heads and later Mopar had 576 heads as over-the-counter replacements. But the 576 heads were discontinued several years ago. I believe any of the same heads with 2.02" valves installed, as well as the original 894 X-heads, are legal on the 360/360hp version.

But we'll just have to wait and see what NHRA comes up with and if IHRA will adopt the findings. Like in NHRA, IHRA has been making judgement calls on their Stock heads.

Re: IHRA Take on Runner Volumes
 

I spent alot of time and $$$ 12 years ago to have my heads pour legal,so what do they do,quit pouring.I've seen heads that looked like the holland tunnel on lots of engine combos,so it would be hard to keep up with those.So guys you have till 2010 to "GO FAST",hopefuly.

Re: IHRA Take on Runner Volumes
 

I always thought this was supposed to be fun. Too many sticks in the mud most of the time though.

You all have fun with your heads up hoorah. I will keep on hiding in a class where I don't have to worry about heads up... and have more fun while I am there!

Re: IHRA Take on Runner Volumes
 

If the only time they tear anyone down is when they set a record, what difference does it make? What do you get for setting record in IHRA? There is no heads up for the championship, no random teardowns (that I've ever seen or heard about) so its all just a no box bracket race. Who really gives 2 ****s what the runner volumes are?

Re: IHRA Take on Runner Volumes
 

Exactly.

Re: IHRA Take on Runner Volumes
 

There need to be some sort of rules or class racing will cease to exist. There are already enough racers who can afford to do more than I can to be fast. Teardowns may not be as common as NHRA, but I don't mind the possibility. There can be heads-up races to go through at events leading up to the championship run-off. Otherwise, why not just race locally?

Besides, I like to give the people who help me out a little recognition on the records page and it usually gets an extra pic in the paper.

This brings to mind the "divide and conquer" strategy. Seems like some people want class racing to be "open", JUST like a bracket race so it can be "fun" while others want to combine Stock and SS. My opinion is that both ideas stink. Don't build a class car if you don't want rules to worry about and if you want Stock and SS combined, build the more expensive SS car. If port volume specs come out for Stock, that will be the best thing to happen in the class in a long time. Stock isn't perfect and will never satisy everybody. But if everybody want something different, the class will be divided and disappear, and may take SS with it.

Re: IHRA Take on Runner Volumes
 

I think if you have nothing to hide you don't have anything to worry about.

What is going to happen when these runner volumes are published and the numbers published are 20 cc's bigger than a racers perfectly untouched stock heads? Does the racer get to "acid" their untouched heads to match the approved numbers?

Re: IHRA Take on Runner Volumes
 

Says the same thing for SS! Seems both are trying to dumb it down, getting more and more like AHRA all the time. Too many classes for lazy guys to hide in, and too soft standards. Guys will start racing rental cars if it keeps going like this.

What a joke!

Agreed but lets face it, every car has something in the GREY area if its looked at hard enough. I didnt say ILLEGAL, I said GREY area. Now after saying that what if a racer spends more time in the tech trailer telling BS stuff on other racers than his own pit area, to the point the tech guys are tired of it. And yes I'm beating around the bush on the this topic.

Re: IHRA Take on Runner Volumes
 

Herb, I would say that tech needs to have the integrity to tell the racer to put up some protest money or leave the teching to the officials. I have seen Smith and Olynic (never could spell his name) do that on several occasions in the past. Also saw Olynic(sp) give out the worst %$# chewing I think I ever heard and threaten to disqualify a racer for looking over his shoulder at the fuel check sheet.
