Aren't the rules the same?
On the other hand, if you can run increased boost, why would you NEED "enhanced flow" (short-side radius mods, acid-porting, etc.) when you can cram it in there, regardless?
Then again, if you had BOTH.... 
Bill, just wondering...
One question: Since you got me straightened out RE NEON heads, and valves, is your new race car the SOHC model (engine)???? |
The point I was getting at is, the turbo cars do it with boost very cheap and effective. It seems like you and some other racers are jealous that they have to spend upwards of $5000 to achieve what a slight adjustment does on a turbo car.
If you think head flow doesn't make a difference. Retake horsepower 101. The srt4 motor has a turbo half the size of the early mopars. and it makes over 50% more horsepower. The early turbo cars are out of flow because of the cam/head below 6000 rpm. You can put 40 pounds of boost to it and it ain't going to flow much more. Boost basicly only effects the intake not the exhaust. You still have to get rid of what you cram in there.
As far as my motor goes, One reason is you can't get a cam over .410 lift in a sohc head. Plus the fact with the dohc that I can change valve overlap with out sending the cam back.
Now maybe thats an unfair advantage. OOOPS I forgot they don't even check overlap in a stocker, let alone a modified motor.
