Car is a 1999 c5 M6 stock ls1 intake manifold.

Ok guys just installed:

TSP 1 3/4" Longtubes
TSP 3" Catless X Pipe
Custom Ground 233/238 Cam from Martin @ Tick
BTR platinum .660" Dual Valvesprings with Titanium Retainers, new seats, locks
New Viton Stem Seals
Comp Chromoly Push Rods
Ported and Blue Printed LS6 Oil Pump
LS2 Timing Chain
MSD 8.5mm Wires
NGK TR55 plugs

Let's see what everyone thinks

 

Ok I'll start the game:

380hp/365tq

Who's next!

 

No other bolt ons besides the exhaust? Thats not a small cam for an LS1 I say 390/375.

 

Just full longtubes, orx pipe, slp powerflo, blackwing intake, then the cam package!

 

400/380

 

Exciting still trying to score this local ls6 intake, and swap before the tune on Monday!!

Keep the guesses coming!

 

410 rwhp 385rwtq with the ls6 intake

 

Ok guys cars getting tuned tomorrow! I will post the sheet when I can!

Wish me luck!

 

Did you get the LS6 intake?

 

We need results!!!

 

Ok guys results are in!

It made 381/350 to the wheels.

I was not able to make the ls6 intake deal go down sadly!

 

With an LS1 intake that is not bad.

LS6 will put you at 400/380 pretty easily I bet.

 

Hey Martin do you think and ls6 intake makes that much of an increase? I figured that might only net me like 10/10 hp/tq more?

 

On a bolt on car it's worth 10-15hp. Cam only I'd say it's worth a good bit more. Might as well go ahead and drop a Fast on it.

 

So what if I did an LS6 intake, new heads, and a ported say LS6/2 TB could I hit 430?

 

Here's the graph!

 

I think that would be within the realm of possibility.

 

I am curious as to what the goals for this custom cam were?

Boostedfury- why did you not go with an off the shelf cam? what were you looking for with the custom grind?

 

Initially I had hoped to break 400 but the plan was with an ls6 intake manifold and 25% pulley but those two were never installed..

Reason I chose custom spec I figure go to a professional who knows the ins and outs of the motor over my lack of knowledge!

 

in the end a custom cam will always be better suited rather than any grind off the shelf, because it will be custom suited for your goals and current mods. Plus alot of people often buy to big when they get a off the shelf cam.
