what can our stock internals handle as far as whp? Also what clutch should i get if i am looking at around 400whp?

 

dont know exactly but its been posted alot. plenty of people above 400whp on stock internals, its all in the tune, and supporting mods. also clutches are usually based on tq, so whne you figure your tq out we can let you know which clutch to get.

 

Every thing I've ever read from GM is around 300 to 315 at the flywheel.
I hear alot about people doing alot more though. The GM #'s I imagine are
conservative.

 

you dont want to push much past 300 whp on an SC upgrade or turbo upgrade.

On the stock SC, dont push much past 260 whp.

 

What about the stock turbo?

 

Are you kidding? there's alot of people with 350whp + turbo set ups on stock internals just fine.

 

theyre time bombs. Hahn recommends keeping it below 350 without forged internals on their turbo setups for a reason.

300 is safe ( ish ). Honestly, pushing the engine past 300 whp on stock internals is asking for trouble.

you can make higher numbers "safely" on a turbo setup than an upgraded SC. If you want to blow your **** up, try running an undersized pulley on the stock SC.

 

86k miles on mine.
350+ to the tire.
300+ ft lbs t the tire.

has been over 300whp for roughly 50k miles.

jussayin.

 

there are plenty of people who have blown their **** up, and plenty who havent. Is it worth the risk to me? Hell no.

if youre going to do an entire build, you should always start with the engine and work your way up. This is just good practice.

 

people blow them up due to stupidity. not power.

 

they're doing it wrong .. stock internals can easily handle 350+ if tuned correctly with the right mods

 

but why half ass ur build? Why not do it right the first time with pistons? Why not build it and push 400 whp instead?

You guys really make me wonder sometimes.

 

why crack open the motor when you don't need to ? these damn things can handle 400 whp WHEN TUNED RIGHT is the key

 

x2 !!!!

 

done right with right mods... what are you referring to when you say right mods. i get the tune part but not sure what you mean about mods.
