i have built engine and went to dyno. i boost 14-15psi and get 450hp and 281 torque. do you think torque is low?

 

holy crap that is alot of power for 15 lbs of boost what do you have done and can you put the dyno chart on we have a turbo car that ran about 430 with 290 torque so that sounds right just low boost

 

what kind of engine do you have, what turbo , all that info would help

 

ya. post setup PLZ. I want to know...good numbers too btw. ****, tq is not always a good thing when it comes to street. Tq=wheelspin.

 

gsr sleeve
83mm je 9:1
crower rod
balance crank
head port by myself
crower turbo cam, spring, retainer, valve
venon intake manifold with 70mmT/B
garret t4s
2.5" intercooler pipe
720cc injector
hodata
this dyno is with full exhuast system 3" this is main setup.
i do not know how to post picture. anyone can help me to post pic !!!!

 

Horsepower=(Torque*RPM)/(63000)

Substitue your horsepower, rpm into the equation and find what your torque should be approximately.

 

sorry i did not understand your equation. i got 449hp and 281 torque at 8600rpm.

 

depends on your motor setup. but either way be happy your car made it off the dyno go out and race and have some fun!!

 

nice numbers! my setup will be similar minus turbo cams. Who dyno your car?

 

DSR dyno my car.

 

most the time big turbine housing make you run short on TQ

what size turbine is on your turbo

 

it say a/r 70 on turbine

 

Your rpm and torque essentially create your horsepower. The physical relationship between both the torque and horsepower is almost dead accurate. So your torque is around what it should be for the given horsepower and rpm.

so where did u get 63000 from? it has always been 5252 i thought.

280tq is pretty high for 14lbs of boost. usually tq stays pretty consistant w. boost levels. 14lbs usually yields 240tq or so unless u run a real big turbo. Reason ur able to make so much hp with such little torque is because of the high rpm's in the hp equation.
