Dynamometer Results & Comparisons - Cam only (VRX5) Dyno Results

Just got my car back...the numbers seemed a tad low, but overall I am pleased.

Dropped car off with the following mods (all done by previous owner):

Hooker longtubes/Spintech catback (no cats)
BBK 80mm TB
Lid
Moser 12 bolt/4:11 gears


I had them put in a VXR5 cam, dual gold springs and an LS6 intake...

So the baseline was 317rwhp...plus the mods it came to exactly 370rwhp...I was hoping for closer to 400, although I think the MAF/TB and probably the LS6 intake are holding it back a bit.

The gains from the cam is great but the numbers is a little low,.

definitely should be making power as well..

With a 10 bolt rear, you would be really close to 390rwhp, add an UD pulley and you'd be around 400 mark.

What was said here.

370rwhp is little low but it is damn great with 12-bolt/4.10 ! ..

Engoy it ..

Yep the 12 bolt is what took the power. Numbers look good considering that. Add a FAST and UDP and pickup 20-30hp

Thanks guys. Everyone seems to have wildly different opinions on how much drivetrain loss there is between a 10 vs 12 bolt rear. They mentioned the MAF was crap too, so I'll probably get a decent aftermarket MAF and come back with a FAST intake/TB combo.

50 hp gain from a cam and ls6 intake (only) is good! Too many think it should be over 400 when you only made a few changes.

my 12 bolt with 4.10's did not lose any power over the 10bolt with 4.10's.

numbers are v-good considering ur Moser 12 bolt/4:11 gears

my 12 bolt with 4.10's did not lose any power over the 10bolt with 4.10's.

lol how is that possible?
