1Quik7 Posted September 15, 2007 Report Share Posted September 15, 2007 what kind of power can an LS1 make N/A on the 'stock displacement'....prior to boring, stroking, honing, waxing, shaving, lubing or whatever? driveability aside, a car that can barely find it's idle, what kind of numbers can be seen, and ET's? after NAWS? after FI? i know it can prolly make 1000+hp with enough money, i'm talking about realistic parts that come from everyday manufacturers. just trying to get an idea where the stock displacement starts falling behind...and you need to stroke it or upgrade to a BBC. please ignore if this post sounds retarded....because i'm 'rotarded' i have no knowledge when it comes to V8 engines.

V8 Beast Posted September 15, 2007 Report Share Posted September 15, 2007 With the right precautions you can throw the kitchen sink into an LS1. Most Ls1's with full bolt ons make about 380 - 500whp. The ones I have seen close to 500 have big cams and no torque. Most people would say you can safely spray a 100 shot on it without worry. I sprayed a 150 shot and had no issues.

Since you have a post of your dyno right now, why not elaborate for those interested in what it took to put down those numbers? Quote Link to comment Share on other sites More sharing options...

V8 Beast Posted September 15, 2007 Report Share Posted September 15, 2007 Because his isn't a representation of what a maxed stock block can handle. True story. I sacrificed a lot in power so that it was still somewhat comfortable to drive on the street. I personally wouldnt run more than 700hp through a stock block, but its been done.

I am not speaking from experience, but have asked the same question to many NA guys. Heads, cam , intake, long tubes, injectors, on a stock shortblock will give you that figure. I would assume that you ca ngo higher with shelf parts, but you may just as well go bigger cubes and get 500WHP at that point. Hopefully Linn will reply, as he has amassed a lot of knowledge in this area. Is this going in the RX7? Quote Link to comment Share on other sites More sharing options...

Of course you can put all the good parts in it and make 850WHP turbo and it would probably live a decent life. Quote Link to comment Share on other sites More sharing options...

MrMeanGreen Posted September 15, 2007 Report Share Posted September 15, 2007 I've been at 550rwhp on FI for years now, but it IS getting a worked over 347 next year. No doubt about it. Quote Link to comment Share on other sites More sharing options...

You can find people that have cracked the block with 750whp through FI, but then youll find some guy with huge turbos who has been running 750 for 3 years. I say dont risk it. Stay below the 550.

V8 Beast Posted September 15, 2007 Report Share Posted September 15, 2007 With Ray, Linn, Sam, John, Anthony, and like 5 million other LS1 guys on this site you'll be able to build a complete engine and know what it will put out and run before you even have it in.
