383LT1 single turbo 8psi Baseline #s!

[Jay_rich]

OKay guys well I got some of my issues fixed on the car, i think my dsm bovs arnt holding proper bc i cant get over 8psi for some reason.

I didnt have time to really tune the car so I was running around the 11.0:1 AFR

I was bored and there was a dyno day so figured why not see what it puts down on 8psi and 91 octane!

So...

383 LT1
9.78:1comp
Garrett T6 74mm turbo
Intercooled
91 octane
8psi
Th400 to eat some power too lol

First pull
547rwhp@6170rpm
466rhtq@6100rpm

Second pull (2min after told him bring it to 6500rpm but he let out)
583rwhp@6250rpm
491rwtq@6240rpm

So as u see I gained 36rwhp from 6170-6250rpm...im sure i woulda saw 600rwhp if he brought it a bit higher

This is just a base.

The car will see 13psi and racegas soon!

Also street form will prob be around 10-11psi on meth and pump gas!

Sweet car, nice numbers. How you going to fit 15x10 on the rear? What size tire?

[Elliott87iroc]

Nice IROC!

[Kwazrollinz28]

hmmm i've seen this car before, on another site. im not entirely sure if it was you though.

first word RICE for the site name

Sweet car, nice numbers. How you going to fit 15x10 on the rear? What size tire?

15x10 with a 6.5BS and im gonna run a .5inch spacer to even it out. Most guys run a 5.5BS but they stick out a tad, so Ill go 6.5 and use a spacer to bring it out a bit.

Also I will be running 275/50 mickey thompson et radials. Prob gonna end up getting some 28x10.5s eventually tho

I ordered my moser with extended studs.
