when i got this car, i ended up realizing that to get this car to really move, rotational and unsprung weight removal will go a long way. All my work on the car has been focused around weight removal and replacing parts with lightweight parts. You can get this car really moving with all that extra weight shed. it may not translate to much of a difference on a dyno as far as numbers go but for every day driving and track application you can really feel the difference. ive been able to keep up with some cars that were "faster" than my car and have been able to outpace others. I think the key with this car is not necessarely brute force but more dieting and removing the weight at key points on the engine, drivetrain, at the wheels, etc. for example i have replaced the following on my car, pulleys, driveshaft, clutch/flywheel, lighter weight wheels, intake, stage 2 tune, completely free flowing exhaust to include header, stuff like that and it has made a world of difference. im still not done as there are still modifications out there that i can get that will enchance the car even more from where it is now. My goal is to eventually hit 300whp N/A. is that possible now? proably not without some boost but eventually down the road yes i believe so. I think 300whp of lagless power will take this car to a whole new level and make it very competitive in all applications. You can also eventually down the road proably incorporate a stroker kit or various other engine modifications like cams and what not. And if you wanted to enchance that even further without slapping on a FI kit, there is always NOS

Watch Nameless Performance. They just picked up a second car for N/A development. ITBs, cams, the whole deal.

NA has its merits but it's damned expensive in the big picture. But, everyone has a different budget and set of goals so to each his own. |

You realize that HP is just a multiplication of Torque and Engine revs, right? So, the higher the HP the higher the torque. It really comes down to, where do you want the torque/power? Do you want more power down low, or up high? If down low, you'll have higher torque, but a lower HP figure, because your producing more torque early on in the RPM range (less power). If up high, you'll have lower torque, but higher HP figure, because your producing more torque higher in the RPM range (more power, but harder to produce high torque numbers up high). I don't know much about f1 engines but do know they rev to well past 10k. I've heard in the range of 18k-20k+. That would have a lot to do with why they don't need a lot of "torque" to produce good power, as those engines wouldn't need big torque numbers with the high RPMs. |

I believe Ferrea claims to have built a 300hp N/A track car ... haven't found any more info than that but it was in an interview at a trade show. Built motor though with their upgraded ferrea valvetrain and different cams I believe.
