hummer h2 with sts turbo , need help
hi there,
i have h2 hummer 2004 with sts turbo kit and a cam with 220 durasion 560 lift 112 lsa
first question ,
is this cam good for my setup ? specially that i need to decrease the sound of the car i dont need loud sound . i need some cam that is slightly better than the stock and has a low sound as the stock or higher a bit
also the sound of the turbo is very loud cos as you know the turbo is on the rear and they took the muffler out . i heared ppl are using magna flow 40 series after the turbo to decrease the sound is this ok ?
any other recommendation i will be happy to know them .
if the magnaflow muffler is just fine whats the model number and specifications .
thanks in advance

the lsa on the cam is to little....other than that its not gonna be "bad"
and yes people have put mufflers after their turbo
would you mind posting pics of the kit on the hummer just curious

I have an H2 company car. The engine bay is huge, what made you decide to go with an STS vs Front Mount (no packaging constaints). Considering how slow this thing is off the line, i would think a front mount turbo/twin screw blower would be ideal...no need to rev high in a 6K+ lb SUV.

That cam is onyl slightly larger then a stocker. The LSA on it is not desireable as u want a longer LSA. I think that since the cam is so small u prolly wont have any issues but im not sure. The issue it could have is that since the cam lobes are seperated by so little space u might end up haveing a exhaust valve open at the beginnin of the compresion stroke which would cause the boost to blow by. But like i said i think the cam u have is small enough that the LSA wont effect anything horribly. GL man

i contact lengenfelter they have a cam that is ,
208/230 .554/.546 121CL
they mention that this cam will not vibrate the car it will give good performance and will act almost as a stock cam but with better performance ,
what do you think guys

U cant go wrong with Lingenfelter. They do **** right. And as u are lookin for stock sounding then that might be teh cam for u. Im assuming CL is LSA? If so i never seen a cam with that much LSA. Not that thats bad jsut sayin that far lol.
It should definatly help ya. GL man

1. int. duration + exhaust duration = A
2. A/4 = B
3. B - LSA = C
4. C x 2 = overlap
