[thesoccerboy20]

im still more of a classical motor kinda guy but this motor sounds good

[thevettedude66]

supras are overrated man nelson racing engines put a tt 427 in a supra cause the 2jz keep falling apart at 1300 hp

[FastisFast]

really thats it? I mean this is a built LSx with boost and only 721 Crank HP? Hell Ive seen stock motor supra/s2000's do over 700whp with just boost... maybe its just me but I was thinking this thing would make over 1000whp. My friend Ray, his Camaro (LS1 has bolt ons and making 550whp)...

[AtlantaPerformance]

This was just the break-in on the engine dyno.

The setup made 1012 rear wheel horsepower on 18 pounds of boost.

[FastisFast]

got ya, that makes more sense. Whats its displacement? What size are the turbos?

[AtlantaPerformance]

434 cubic inches. 66mm turbos.

Customer wants to switch to 76mm turbos.

[copleygsxr]

@AtlantaPerformance wow you should be over 1200 with 76s

[InitialDirt]

With the new Tall deck LSX block, would 8.5L be made without any harm to the block? i know it can achieve 511cu but can you push it to 525?

[jimbo98z]

@FastisFast Your friend has an LS1 car that makes 550 to the wheels with bolt ons? This I have to see.

[FastisFast]

@jimbo98z Yes, Bolt ons and a small shot. That was last years setup. He went for a fully built 404? or maybe a 406? Im not good with Chevrolet motors. He made over 540whp on the motor this year and 711whp on spray. Pretty nasty.

[cakes1284]

sick motor!

[allbaugh04]

Is this like a stroked 408 or what? Pretty sweet :)

[MrChompenstein]
