I know a few of you guys were interested in what type of numbers the Crower 403 cams made in an LS. I finally got them put in this weekend. Here are the results:
150 whp @ 6500 rpms
125 lb/ft tq @ 5300 rpms
[RED]Baseline Run[/FONT] = aem cai, comptech header, 2.25" carsound cat, comptech exhaust = 132 whp, 121 tq
[BLUE]Dyno Run 007[/FONT] = same setup as above + Crower 403 cams, Crower valve springs, B&M fpr set at 40psi @ idle, aem cam gears (intake +1, exhaust -1), SAFC
Here is a dyno plot of the cams untuned vs. tuned
[BLUE]Baseline Run-untuned[/FONT] = i/h/c/e, Crower 403's, Crower valve springs, B&M fpr set at 40 psi @ idle, timing at 16 degrees, aem cam gears (0,0) = 148 whp, 123 tq
[RED]Final Run-tuned[/FONT] = same setup as above except: aem cam gears (intake +1, exhaust -1), SAFC tuning = 151 whp, 126 tq
The guy who tuned it did an excellent job with flatening out that nasy dip in the power curve that you can see from 4300-5200. It dyno'd pretty well, powerwise, without any tuning what so ever putting out 148 whp. The guys that worked at the shop said I could have hit 155whp, but I told the tuner that I was more interested in fixing that midrange dip than boosting the peak power, he said no prob. And that he could probably pull out more power in both the midrange and top end. He didn't mess with the fuel psi at all, adjusted the cam gears once, and the rest of the runs he just kept toying with the SAFC to get better power.
My only beef with this mod, was/is the idle quality. When they initially started the car it sounded like poop!!! ~If these things are supposed to have a smoother idle than the 404's, I'd hate to see what those things idle like!~ They toyed with the fpr and safc to get it idle smoother, but its still a little lopey when I come to a stop. Hopefully I can fix this myself today with the help of StyleTeg's idle adjustment article.

Oil squirters are not for lubrication damn it.
