roush cars in stock and super stock

You reckon NHRA's gonna buy a bunch of telltale boost gauges and then loan them out for free?

Evan:
I can't believe you think the majority of us are nieve enough to buy your story about blower pressure vs. performance. Just one look at the power adder classes in NMCA, NSCA (defunct), OSCA etc.

I competitively raced in NHRA Modified Eliminator years ago. The racing was fair and very competitive and for the post part, no one or no class had any advantage. That was with two exceptions.

The first was the Mazda rotary. NHRA Tech could not figure out how to measure and calculate the cubic inch to weight ratio (still a problem in sports car racing) , so it dominated for a time.

The second, and relevant case to this thread, was the turbocharged Pinto of Buddy Ingersoll. He ran rampid through Modified eliminator and turned up the wick only when he needed to. No rules as to intercooler, boost pressure etc. He went as fast as he needed to in any weather and took a lot of money from the rest of the Modified racers.( as well as loosing a lot of respect.)

The point is, you cannot race a blown (turbocharged, supercharged) car in the same class as a naturally aspirated one.

Shoe polish race you say? Yes, but someone in the same class will suffer, be non-competitive and get run off. Only strict rules and guidelines (boost pressure, pulley size, blower mods, intercooler specs) will keep this in check. And as I said on another thread, we don't have that ability to tech them.

Face it even three brands of cars all with Blowers would not be reasonable to tech...The good part of aging is having watched it happen before and recognizing the slippery slope coming on the horizon AGAIN>
The young guys at the manufacturer need better input on this project, or cooperation or....? Recognizing the weakness of our sport on the technical side and the loop holes previous racers have used to exploit the others makes it hard....

I happen to support Evan's quote since I have done lots of research and work on the Series 1 and Series 2 Buick S/C engines and have experienced the same issues. They are generic to S/C engines.

NHRA calculated the CID on the rotary engine in the same fashion it was doen in IMSA, SCCA as determined by FIA with a multiplier factor of 2.2. I always felt Modified Eliminator was terminated due to the Modified Compact cars. It is a known fact that many of the sponsors complained to NHRA about the car too.

When Buddy Ingersol had his Pinto, intercoolers where not allowed in the class and the class was limited to specific turbo models and parts numbers; which happened to be small sized. By the way, everytime he turned the wick, he had to take the engine apart, either replace it or repair it. About loosing respect...it is quite bold to say so about Buddy. He has always been an innovator and smart guy; he went through the same issues when he showed up with the Buick Grand National. If many were upset about his car, why did not others build a similar car? Too embarrased to race a Pinto with a 4 banger because it is not a "macho" car?

There is the ability to tech them and there is a lot of tribal knowledge out there for NHRA to properly factor these cars. Also, you have, although not perfect, the AHFS. Like I said before, the factoring by the AFHS made the Buick GN and T-Types, 1989 T-Firebird, including the Gallina's cars not a good choice.

All this whinning reminds me when the F.I. cars were incorporated with the carb cars; a lot of people started to read their "Farmer Almanacs" to predict the demise of carbed cars and every heads up race to be a win for the F.I. cars...look at the statistics and see the carbed cars are winning over the F.I. cars on heads-up races.
