Im sure this has been asked before but, How much WHP or HP can stock internals handle?

 

550..ive seen more though..but semi reliably 550

 

For a daily driver I would keep it under 550...

 

hey you guys- 550 WHP?or HP?

 

WHP
and for a DD 450~500 is pretty safe!

 

There is no set limit. It depends on how hard the car was previously beat on and will be in the future, type of fuel used/being used, the tune, mileage of stock components, random failures due to other parts (oil pump, timing belt, etccc) and on and on. Assuming the motor is in good shape before hand it should be able to handle 550 whp on a dynojet assuming you only drive it on the street and rarely see boost/full boost. If your trying to drag/road race with 550 whp that sucker won't last long. If you feel like your going to be pushing the limits, either scale the power back a bit or fork up the money for a built motor. Keep the other factors in mind though.

 

450 i think

 

I do 500 + Awhp. On stock botom end internals on c16. But thats only for a drag pass against my oponents who give me money..

Other wise I roll on 14 pounds and make 350 Awhp on 91.

 

in my case, having my motor blow out on me only at 18k miles after a fresh tune, i'd keep it in the 450 range. yeah i've only made 394 whp but the fact that something's gotta/gonna give, and the moment you see it for yourself.....oh boy

but 550 is what ive seen so far with stock internals...wont last long (if you drive like you stole the car) .....if you drive like a grandma (but have the urge of a speed racer here and there...not often though) then your good for a while

 

Wow I thought it was closer to the lower 400 range. Good to know!

 

well the FQ350 and up uses upgraded turbo and Omega pistons and rods.
So i say 350 is the max you should go on stock. People saying 400-500 seems crazy.

 

550

 

gotta love the 4g63...500+ to the wheels is amazing for stock internals...especially for a 35k car

 

lemmonhead, bud you need to research you post. the FQs all use stock internals, and the model name is not the actual whp, if you notice the number they release is bhp, which is the output at the flywheel on a engine dyno with corrections applied to show the loss of power due to normal accesories, alt., water pump, etc.. my opinion is just tune for the simple bolt-ons, and save your pennies to build the motor to be reliable as well as a high output power plant.

 

Yup my boy Juan's car is making 550...gt35r...meth ..cosworth cams ...the basic ****. he is hoping to crack in the 10's tomorrow. Ivey is tuning it tonight.
