Dynamometer Results & Comparisons - Another cam only 500RWHP C6 From Vengeance Racing

Delivering this one tomorrow folks!!!!! This BEAUTIFUL C6 came to us from a Corvette Forum member with ARH longtubes/Vararam Induction/B&B Bullit Exhaust already installed. Baseline #s showed 403RWHP/401RWTQ. The owner was looking for max effort horsepower without a huge sacrifice in drivability in the lower RPMs...

We added:

Vengeance Racing Stage IV LS3 Camshaft
Comp 921 Spring Kit
Hardened Pushrods
Katech C5R Timing Chain
Melling Oil Pump
Milled The Cylinder Heads for added compression
ARP Head Bolts
GM MLS Head Gaskets
Installation/Tuning by Vengeance Racing

STOCK PULLEY
STOCK WATERPUMP
STOCK CLUTCH

We also completed extensive testing of the new FAST LSXR 102mm Manifold on this combo which has been posted in a few other threads already.

The result is 502 REAL RWHP/457 REAL RWTQ with EXCELLENT street manners http://images.ibsrv.net/ibsrv/res/src:forums.corvetteforum.com/get/images/smilies/smile5.gif 101RWHP/56RWTQ Gain from a Cam Kit with a slight bump in compression!!!

Here are a few pics/dyno graph and drivability videos for your viewing pleasure!!!

thats sick. Great job guys!

bad ass ron!!!!! sick to see the power coming out your shop. keep up the good work!!

Great #'s and good looking car!

How much did you mill the Heads? Also is that the stock TB and why? Roughly how big is that Cam?

Ron how was the PV clearance with the milled heads? I noticed that your site says it must be checked.

wow very nice! but the vids dont work for me!

Great work those LS3 Are mean SOB For sure.
Car looks awesome too.

Congrats to the owner but we need some WOT Vids.

Nice Gains

That is impressive. Vengeance RULES!!!!!!!

that is one sick vette its got everything; power, looks, and it gets around town just fine. what kind of wheels are those?

Not sure I would call it "cam only" but great #'s nonetheless!!

was the FAST already installed? it wasnt listed as so. sick numbers either way

Huge numbers! Damn LS3's making us all look bad, haha.

Those are COR wheels. They are pretty cool.

Nice job Guys !! Looks like another happy customer leaving Vengeance Racing !!

That cam makes nice power all thru the RPM range, but that topend KICKS ASS! Can't wait to see this guy take his car for a top speed run. She is going to fly !

Could you remind me about the results on the lsxR intake. Unported it gained 8/9 to the wheels, what did it do after porting ?

what was the reason behind using the Katech C5-R chain? and were the sprockets upgraded too? are the C6's setup weak in stock form?

Also curious. Did you have to flycut?

Im still up in the air for my LS2/L92 head swap and dont wish to flycut.

Thanx guys!!!

This camshaft WILL fit without flycutting IF you do not mill the heads. We wanted the added compression so we milled AND flycut to keep things safe.

Great results.

nice one Ron.

Have you guys used any of the comp 926 springs yet?

We have used about 6 sets so far with great luck... Looks to be a very nice spring/kit

we just installed our first set on a stock cube LS2 that is going in our 98 vette shop car.

looks like an excellent spring kit.

we came by your trailer several times on Saturday and you guys were never there. in line to race I suppose.

sorry we missed you guys.

What lobes?

Ron so let me ask you this. What do you feel is better?

The bump in compression with a slightly smaller cam. (heads milled around 25-30 thousanths)

or running the heads as is with that came?

the one i was lookin at was a 232/236 .600/.600 with the heads milled 30 thous with oem gaskets.

Im concered about over caming with not enough compression.



502 REAL RWHP/457 REAL RWTQ

How much power loss would we be talking about if the heads were ran as is without milling? What did you mill those heads too? stock ls3 gaskets?

nice one!

Ron, Pm sent.

Ron, did you get my pm? Also, what throttle body was used?

badass results.

Do this cam can be use on a Iron 6.0L with around 10:1 compression? Or it need more compression?

Awesome results!

PMs returned...

PWRDbyLS1, I would want a bit more compression for optimal results with this camshaft.

Awesome results! but about how much will this cost me. I need to budget for this mod.
