Re: roush cars in stock and super stock
 

Many moons ago '57 ford 312 supercharged cars started to dominate and were regulated back to their stock pulley.Now is this still the case? See where i"m going!......( I'm not planing on building one)

Re: roush cars in stock and super stock
 

No way with only 435HP. There are many stockers in the lower classes already making 435 HP and they do not go in the 9's

Re: roush cars in stock and super stock
 

I believe that is the rated HP. They will probably make some where north of 600 in real HP.

Bart, you remember the Paxton superchargers? Man, that is a good point. I'm not as old as Bart, but, I have seen a (Thunderbird Special)Y-block Ford.
The Buick Gran Nationals were killers, for a while, as well.

Re: roush cars in stock and super stock
 

The effectiveness of "forced induction" is a matter of degree, I think.

In the final analysis, it would appear that the amount of boost available at the intake valve is responsible for the amount of horsepower produced, all other things being equal.

Factory horsepower ratings are generated at some specific amount of boost on forced induction engines.
It shouldn't be too difficult for NHRA Tech to obtain the figures for the boost levels that were used to produce the rated horsepower figures that the factories claim.

Some other racing organizations are using onboard tell-tale boost gauges to monitor boost levels in competitors' cars to ensure that nobody is running an "enhanced" turbo system that will produce additional horsepower from altered boost levels (since this throws factory-generated ratings into a cocked hat.)

NHRA could do this without much effort.

It would seem devestatingly simple to me, to attach a tamper-proof, telltale boost gauge to the car in question, and when the vehicle comes to the scales after a run for his weight/fuel check, the Tech simply looks at the telltale gauge to ascertain that the maximum boost for that engine has not been exceeded. He'd then reset the gauge to zero for the next run. Maybe that last step wouldn't even be necessary.

There are precious few turbo cars in competition, so this scenario would not be played out very often. The max boost levels for all eligible cars would be provided to the Tech at the scales along with all the other tech information they get from Glendora. All the Tech would need to do is consult a list.

This system could also be utilized on supercharged cars in exactly the same way. Using this system would relieve the Techs from having to become expert in the art of recognizing non-stock (non OEM) turbo and supercharger hardware, to a large degree.

The bottom line would be, if the boost levels remain within the "stock," parameters, then the equipment probably is, too.

Just my 2-cents...

It appears too many are getting their feathers ruffled and coming with ideas and suggestions to regulate these cars. For starters, many are afraid when they are put outside the comfort zone of carburetors and have to deal with technology they do not know about. Let's be real...these cars have not made a single pass down the track and lots of folks are already in a witch hunt. Let the cars hit the track and let the Tech people do the enforcement. The new guy in charge is supposed to have the background and industry knowledge on these cars. Remember the Buick GN's and T-Types??? They were penalized so much that I have not seen a single one in the track for some time.

Re: roush cars in stock and super stock
 

Problem is if you limit pully ratio these guys are going to try to turn these motors through the roof and the track will be chasing connecting rods and oil all day. More waiting???? Sounds like fun to me. Yes new tech is cool but have a look around when stock/super stock are in the lanes. I don't see 18-26 year old crowd, who would be the ones interested in these cars, anywhere. The stands are jammed with the mid 30's and up crowd that are saying "i owned one of those". And really 75% of us cant afford a Roush Mustang so really I dont care to see the full potential of these cars that "could" be sitting in my driveway. Call me old school (im 28 by the way) but I like the class the way it is and we all know that they will be rated at like 240hp and go 1.6 under the index just like all the other bogus combo's. Id like to have a chat with the clown who does the factoring some day to ask him "What are you thinking...really?" Ya im all for letting the shoe polish do the talking but when it comes down to a heads up run and the guys got 5 tenths in the bag because he gets to ice his intercooler and flick some keys on the laptop...ya thats super stock all right:rolleyes: Might as well enter Appollo 12 in J/SA. Should go like 2 light years under the index.

I know one of the engineers in the Corvette program, there's a lot more done in house than you might think.

The Roush cars are also intercooled. That will also help a little on the heat build up.

Re: roush cars in stock and super stock
 

I look forward to seeing these new Mustangs racing. I’m glad that Detroit has recognized NHRA stock racing and has made an attempt to market models that are purpose build. It has been done back in the 60’s so why not now. So what that they are Roush and not built by Ford. With higher fuel economy (CAFÉ) requirements, it’s a way for Ford to not get bothered by the EPA ratings. Ford built the supercharged Cobra in 2003 and 2004 and it is rated at 390 hp. I don’t read any complaints about that car. In fact that car has more potential than the ROUSH since it a 4 valve head. The Roush is a 3 valve head on the same 281 ci block. Last year a lot of people complained that the FI cars were being combined with the carb cars. It seems that everything has worked out fine and the FI cars are not completely dominating all the classes. I don’t think that the Roush will cause too much trouble for the high compression big blocks from the 60’s, especially for a small 281 ci being rated at 435 hp from the start.

The car has been in the guide for a couple of weeks the weights, HP engine specs all there, take a look before you jump the gun. Trust me I love sixtys muscle cars for that matter all muscle cars and race cars alike. You are just missing the point the OEM,s would like to run current cars and curent power it only make sence. I am aproached at the races all of the time, " is that a 3 valve or a 4 valve a 4.6 or 5.4 and so on" when I explane that is has a 1971 power plant. it sparks confusion for the most part. That was my choice from the begining and have invested quite a bit. so that is how it will stay for now. however I believe that the cars that run stock and super stock not GT with current cars and power will get the attention. and that attention is what the OEM's need.
