2014 Conti Challenge Round 1 Daytona

Dwnshift

The Z28s are $350k machines built by Pratt and Miller. Their World challenge version is $425k.
They are way overbuilt for both series.
The 7 ltr v8 Camaro makes 500 hp and 475hp in stock streetcar trim. As advertised.
Throw in a KN filter and ECU mapping who knows what it makes. The throttle body is 9mm with an 80mm restrictor which is probably about 25-30 hp and still makes 475 ftlbs of torque.
If you see the cars up close and know rules for the series... They were given very thing they asked for and a lot of it is beyond the spirit of the rules for the series .
When cars in this series are allowed to put in racing pedal boxes and dual master cylinder systems , lexan windows, its beyond the intentions of the series.
Again $350k for a Contincar is insane and all It will do.. Is kill the series.

Since when are big racing series fair, sane or not political? Chevy wants to sell more Camaros so they influence regulations. Guess the solution is Drive a Camaro. Or drive a car that strong manufacturers support and influence over sanctioning body. Not first or last time a manufacturer is given preference in a race series. $350K Camaro? ...No thanks. You could build a pretty nice Porsche for that amount. Chevy must want the win to tout the whole new line of track ready cars they are marketing? Too bad you cant counter the Chevies with a well developed GTR.

I agree, so many big manufacturers have bent and twisted the spirit of the rules and made "homologation specials" over the years just to make a given race's requirements it just seems moot to make an issue over it. Simple solution is boost the minimum production figures up from the 500, which many big manufacturers could easily eat if the sales don't match, to a few thousand.

Good luck BJ/Doran! I always look forward to watching you guys race.

With the bankroll of the Camaro teams, seems they would fit into a Tudor class instead of CSCC. I was going to look it up .. with the changes my old memory is lost as to what is in Tudor now... and their website doesn't have an easy place to see all the classes, differences, etc..

Just do us a favor and pass those chumps -

Yea, total B.S.

The best part is that 80mm restrictor isn't doing ****. That 80mm is over 3".

3" Pipe
700 cfm = 162 mph = 0.21 mach
800 cfm = 185 mph = 0.24 mach
900 cfm = 208 mph = 0.27 mach

Having tested many LS style motors for intake speed they average around 200mph. Given that is going to be a Pre-Throttle Body flat plate restrictor you can bet that its still flowing 800cfm.

So 800cfm to Lbs/min is give or take 14.5 so 800/14.5 = 55lbs/min or 550hp

So yea... Likely costing them 1-2hp if that..
