Kinda anxious about what my build is gonna do but now I'm stalled for some parts so thought I would ask, what is the max boost and whp I should safely make with my setup :

LSX 388 fully forged/built, blueprinted and balanced 10.1 CR
GMPP LS3 (4 bolt) heads - ported, upgraded valves, dual springs, upgraded trunions, 3/8 BTR push rods, TSP stage 3 pd blower cam, LS9 head gaskets
ARP hardware throughout engine and heads
Kong 2650 supercharger, 8 rib belt setup, 2.75 pulley, 112mm NW throttle body, trunk tank
1700cc ID injectors, dual 450lph pumps
E85 (Flex setup so tuning for E85 and 93)

Those of you who have or tuned similar setups, what is the max boost and whp I should make approximately?

 

I just subscribed. I’m interested in seeing the build and results .

 

Also tuning in to see how this project comes along.

momo do you have any pictures you post of the kong 2650 installed? Would love to see that!

As you may know I am currently running an LSA on a forged 408. If I ever win the powerball that I don't play I am hoping to go to a kong 2650 if I can use my Olson modified LSA snout on the Kong?

Only other flaw in the that plan is I don't have the fuel system or the rest of the drivetrain to support that kind of power lol.

I would be surprised if you didn't make 1000wheel with that combo.

 

Hey Mr. Black! Yeah its not fully done but here's a pic of how it looks. I'm still figuring out the tensioner offset, etc.

 

Those 2650's will make some power. 1000-1250 wheel depending on how hard you want to turn it.

 

In my opinion you need 6 bolt heads. Blowers come on FAST and you're gonna have trouble holding a head gasket

 

Thought I'd come update

Car made 852whp and 784 Tq at 18 psi boost - Kong 2650, E85. Car could have made more but this was the highest we could get with virtually no belt slip RELIABLY. Bear in mind this a C5 Corvette - they said this blower would not work with this car - I wanted to be different

Car was tuned and some of the belt drive modified at Speed Inc. in IL. I've been to many shops over the years with different builds - these guy have been the best hands down! Glad to give credit where its deserved

 

I don't know how I missed this. Congrats on having some serious fun!

You never did say, what snout are you running on the 2650?

I am now looking into the future between the kong 2650 and the Whipple 2.9l C6 LS3 blower!

 

Very nice numbers, curious to know where that 784 ft/lbs. of torque comes in.
