i know lame question, but i do have a point. ive been searchin here evans-tuning and HT tryin to figure what should be something simple out but most big power dynos i see are gsr's

how much power have you guys seen out of LS motors boosted. bore, turbo, cams whatever doesnt matter. basically im having a hard time finding setups that make over 300whp. i know more than that is possible with cams/headwork maybe sleeved/bored engines but not sure how much.

 

300 is possible on a stock motor, If you're going to build the motor you might as well go for the vtec head though. The ls head is kind of a bottleneck

 

chris (xenocron) made 300whp on his stock ls motor. go to his website. ------------- for more detials

 

wich is the point of my post. i want to know how much.. ive seen dynos of stock LS's with turbo cams making 300. I dont really mean a stock motor, i was thinking maybe minumum forged internals, cams, headwork blah blah

im trying to pinpoint if its head flow or valvetrain limmitations (ie cant rev as high as vtec motors cause im thinking of ways aroudn that)

 

That head is trash unless you port the ---- out of it

 

anything else constructive maybe?

 

I would think we the appropriate bottom end along with some cams/springs and a intake manifold you could get into the 350-400whp range before you would need to look into doing some serious head work.
