Lo3 motor, 130,000 on the clock, it doesnt have all these mods yet, but will in a few months.

350 throttle body and intake, open element, shorty headers, cat delete, flowmaster 80 series catback, lb9 heads and cam, mail order tune (13hp dyno-tested guarantee)... also putting a t-5 in it, so less drivetrain loss...

anything else we should consider that doesn't require a tune, bigger injectors?

last question is do we need to upgrade the fuel pump?

 

i recon around 220-230 at the flywheel. Fuel pump
upgrade may help and will allow you to bump up the
pressure a bit...

 

thanks!!!

haha we will get her dyno tested... closest one gets a prize

 

"350 throttle body and intake" 0 hp here, 305 and 350 are the same.
"open element" a CAI will be much better.
"cat delete" maybe +1hp vs a 3" higflow cat.
"lb9 heads and cam" Well you know how much hp your particular LB9 made with much better exhaust, much better tune and better CAI, vs LO3.
"mail order tune (13hp dyno-tested guarantee)" Good luck, I suggest EBL.
"t-5" +10hp over a th700r4.

What are the cam specs of your LB9?

Because there is a prize I say, 180rwhp @ 4500rpm.

 

not sure of the specs yet, whatever cam i can use without needing a tune...

 

Ok. 170 rwhp. And no you dont need a higher flowing fuel pump in this case.

 

really, that low? i'd think the heads and cam would make at least 20hp more and from what I hear, headers are a good 15hp over the stock manifolds and restrictive factory y. we were hoping for a good 190-200 rwhp.
