Forced Performance 4R Cams
« on: November 05, 2010, 02:19:23 pm »
we just finished dyno tuning a Chel's 2.3L 2g with some great results... and  judging by the grin on his face when he herd the new numbers, im sure itll be no time before he's arrested and car impounded with the new speeding laws in full effect. 

Chel had us tune his car a few weeks ago resulting in approx 330awhp @ 25psi with meth. we had hit a peak of 350awhp but after smoothening things out, we settled on 330awhp. 

TODAY - the cams were swapped out in favor of some FP 4R I/E Cams along with some FP Beehive valve spring set.  cam timing remained stock and the cat was removed.  boost and meth remained the same.  we hit a peak of 470awhp but settled at 460awhp.  APPROX 120+ AWHP GAIN!

idle seemed fine to me on the few start up i saw ... the overall pulls on the dyno sounded mean and fairly decent spool.  the 6262 is comparable to a gt35 turbo but with a tad better spool from the billet wheel.  the overall duration of the FP cams is nothing too crazy, but well overall design with their lift, overlap, rap rate, ect.

maybe chel can report on this thread

Was the original cams stock or aftermarket?
Any guess how much better than my 101300 Comp cam?

I heard Chel's 4R cams at the Kruise for Kids.. 
Lumpy at 900 rpm but nice pulsing strong idle (with a punch) at 1000 rpm..
Not too loud either..
Smoother than the BC 280 cams.
My comp cams 101300 sounds close to stock.

So the only thing you guys changed are the cams?  If so those are really good gains
