I'm about to fit SVT cams to a non SVT which has ported heads, Extrude honed UIM and SVT TB.
I currently have 160wlbs torque at 2700 rpm, obviously I'll have more power higher up with SVT cams but will I have less torque at 2700 rpm with SVT cams?
everyone has done it, lots of people have 3.0L. and it does not cost as much as having port work done.
Only have the SVT cams a short while.
I guess if I put headers in at the same time torque would be up anyway, but would noise be up also?
the .3 compression points are pretty low actually. The magic is in the cams, not much from the compression.
The headers combined with the headers will give you a big low end torque boost and the cams will take care of the top end. The combination is awesome. As long as you keep using a muffler, resonator and catalytic converter...even straight through designs, it will not be too loud. It will sound better, a bit more aggressive.
Would a rechip change the compression or is that mechanical?
