does anyone know if there are any companies that make performance cams for the 3.1??? i'm looking to get a little more power out of mine for auto-x racing

 

Take a look at the stickies. ---> LINK

 

those cams don't have the rpm range i'm looking for...

(trying to stay around 6k-6.5k rpm redline)

 

thats pointless due to the factory intake design power drops off fast after around 4,800 rpms. so even if u got a high rpm cam it will be mismatched to the rest of the motor

 

ah didn't know that. i couldn't remember, but isn't your car spinning out to 7500rpm or something like that project???

 

the turbo makes a world of difference compared to an n/a motor, a turbo will move air at rpm vs the na setup

 

ah ok. so i'm guessing there isn't any high rpm N/A manifolds available for our engines then?

About the 3rd post on down, nothing ever really got resolved, just alot of arguing. But from what I understand there are really no good aftermarket intakes for these cars.

 

k, well what i understand from that thread is that the heads and TB are causing the intake restriction and keeping the engines from being good up top. i mean i know my stocker revs higher than 4500rpm (6k rpm redline, had it there a few times during auto-x races). so from the looks of it a new TB and P&P the heads will give me gains???

 

yes that will get u more gains then swaping the intake.

the intake flows well enough as it is, the reason it drops off power at 4-4,500 rpms is cause of its long runner/small plenum design

contact this guy for a tb

ull prolly have to send him ur stocker to get the correct linkages put on it but its cheap

 

i'm still kinda new to this stuff (building up a performance engine). do you think you'd be able to explain how the LR/SP design hinders the topend rpm???

 

not without getting all technical and its 12:30am if noone else explains it tongiht ill explain it when i get back on the pc tommrow

 

alright, thanks
