RE: LS1
american engines suck. the s2000 has a 2.0 liter 240 horsepower engine, thats the most productive engine ever made. if it was a 4.6 liter it would have twice the horsepower of a gt. lol just wanted to say that. but its still a 2 liter so thiers no torque! honda needs to make v8 lol

thats 120 hp per liter a NA dohc 4.6L with the right tune si making nearly those numbers. a yamaha r1 is putting down 185hp per liter.

Thats becasue the S2000 makes very little torque down low. The High HP number comes from high RPM Torque X RPM/5250 = HP.

All of that power and the S2000 is still slow.
Not to mention that to even chirp the tires taking off you need to drop the clutch at like 6000rpm.

My Suzuki RG500 1986 had 230hp per liter with few mods, with full mods you can get 320hp per liter for a street bike, and a full race bike 500cc had 200hp= 400hp per liter, a smaller engin gets more hp per liter, RC car engin, if thay had the same HP to liter, lets say, 7 liter it woudl have 5000HP

The LS1 is simply a great engine for hot rodding. It is very light (pushrods have some advantages and one of them is avoiding all the weight of OHC heads) and the engine is quite low with a good center of gravity. The stock heads breath nicely and take to porting extremely well. The engine has no oil circulation or cooling vices like some other engines around. You can stroke it 1/2 inch without any machining of the block and the engine will take cams with lifts up to 700 thousands without breaking anything or needing special machining (although I would not go over .550 without installing aftermarket shaft mounted rocker arms). It can rev to 6500 stock and 7250+ with aftermarket parts. Vices or problems? The deck height on the heads is marginal (AFR and other aftermarket heads fix this), there is no completely satisfactory heavy duty oil pump available, and the engine is very tempermental about combustion chamber shape and piston top spacing, so special care is needed there.
Headers, cam, and catback exhaust alone with get an LS1 to about 370 RWHP, add good aftermarket heads and you have about 425 RWHP and a very broad torque curve.
My experience is that the limit for durable HP on the LS1, 2, and 6 with stock internals is about 500 RWHP, at least if you use that HP. I had one come apart at about 550 RWHP during a drag. We were abusing it and pushing our luck and we knew it - can't blame the engine. The LS7 (427) in the new ZO6 is a different matter. I imagine it is good to 650 RWHP.
Earlier (98-2004) LS1s do take Supercharging well enough, as they have only around 10.5 compression and can run about 7-8 lbs, at which they put down around 520 RWHP with intercoolers and 8 lbs. 2005 and onward LS2s with their 11+ compression take it less well but people still run 4-5 pounds no problem and some run. The stock engines can take 125-150 NOS dry systems well - within the bandwidth of the stock computer although it sure pays to retune.
