Default Any HP Guesses?

Hello ladies and gentlemen!

I am in the process of building my Corvette with the following modifications listed below.


6.0L LQ4
LS3 Heads Milled .02"
LS9 Head Gaskets
ARP Head Bolts
LS7 Lifters
Hardened Push Rods
222/238 .602/.585 114+4 LSA Cam
LS2 Timing Chain
LS3 Intake
LS3 Throttle Body
80# Injectors
Long Tube Headers
X Pipe w/High Flow Cats
Bullet Axle Back w/No Mufflers
V3 A&A Blower Kit (Should make 10lbs of boost)
Methanol Injection
UPP or A&A Fuel Kit

I should have it fully assembled by early next week, I have it scheduled to drop the car off at Steve Morris Racing Engines next Friday for a good ole tune!

I also have a Spec Stage 4 Clutch. PS, if anyone has any 18" ET Street Tires, Im on the market!


What do you guys think?



Here is a photo of my C5, I had it painted earlier this spring.

What size motor? Why 80lb injectors for a setup with that psi? I had 60lb at 11.3 psi and they were at 78% duty cycle. Are you planning on doubling the boost any time soon?

I just picked 80# injectors based on what my tuner advised me to purchase. Im assuming this pulley will make 10lbs with my set up due to the higher volume LS3 intake and 6.0L engine, it made 15lbs on a LS1 with a LS6 intake.

With my LS1 I ran a P1SC, blower cam, and the 60# injectors maxed out at 577rwhp using 93oct

80lb Inj's = Good! - every build is different!

My guess is 650+ RWHP (conservative guess too)

Thanks,Matt

All of these estimates have me chomping at the bit! A buddy has a 700rwhp Camaro SS with a 5.3L forged and a T76 turbo. I need to hurt his feelings at the drag strip Once the car is done there will be a lot of videos to come!
