  • okay i'm lookin at this video and others in here. the car sounds good. HOWEVER you can't claim 940hp cuz you HAD a 400 shot. I saw the 532 on an engine dyno in the video but NEVER saw anything with the 400 strapped to it.... 532 is great but is typical of MANY LT1 builds. I never engine dynoed mine but it put down 486 to the wheels on motor and 811 RWHP on a 300 shot. And i'm losing like 22-24% thru the drivetrain. That's 620 NA and 1000ish on spray at the flywheel... so wheres the 940 dyno?

  • my electrical for the two stages was wired in my car for the dyno you seen so i could not spray it at that time and that dyno was 92 octain not 110 or c16

  • Nice build. I have a 94 Z28 too...I have a question...why not using smaller turbos like T70's to get 1400hp...and also what crankshaft did you use in that engine? The strongest crank I know of for the lt1 is by Callies is there anything else?

  • turbonetics pick my turbos for this setup 66mm turbo would go to 1300hp peak out and i have a callis crank manley pro beam rod and dimond nitrous piston im changing the piston over right now for 8 to1 compression for the boost

  • great build. why not shaft mounted rockers?

  • that is what my engine shop put in i just put twin t72mm turbos on this motor looking for 1400 hp

see all
