im trying to make 450whp with my setup any info would be great thank you.

the setup im running is a
gsr buttom end with wiseco pistons 81.5mm
eagle rods ,arp head studs , block guard
type r oil pump gsr water pump,endyn breath kit.
i beleave the comp. is 9.5.1 or 9.7.1 i'll have to check again..lol

the head is also gsr thats been p&p by endyn
with skunk2 valve train and endyn flat top valves and im running 98 itr cams with str cam gears,nrg wires

the rest of the setup is jg intake manifold with the hondata manifold gasket, 66mm throttle body with a p2r throttle body gasket,apexi fliter,diy ground kit

the turbo is an sc34 with a peakboost ver.1 manifold and there down pipe, tial 38mm wastgate,percision 880 injector's,and the 600hp percision intercooler, walbro 255. tuned with hondata s200. also the manifold,down pipe,and the intercooler piping has all been jet coated

thats just about everything i can think of so how many psi? also i couldnt find amny dyno's on the sc34.

Isn't 450 pushing it with his setup? I would think by 450hp the turbo would be at it's limits and need about 20 or so psi.

its good for more than 450.. i agree with between 15 to 18 psi should see 450 ish

are u agreeing with me? lol

d3vilishSi

on percision web site they say the sc34 is good for 545whp.

90teg

He is not going to make 450hp on 15psi with a sc34.

d3vilishSi

were are all the sc34 guys at??..lol

Schister66

545hp is a crank horsepower rating just like a 57 trim is rated at 500hp, but people are pushing them to make 420whp....it can be done, but rather than pusing something beyond its limit, why not upgrade to something that is designed for the power goal you desire?

didnt know that so your say 450 is pushing it for that turbo. i would just hate to buy a new turbo i havent even put this one on the car yet..lol

tony n.

i rather get a bigger turbo if you can
a sc34 can probably make 450 but its pushing its limits all the time
so i rather get a bigger turbo and make 450 with less stress on the turbo

Ludster

Try and get a bigger turbo

d3vilishSi

so if i then just want to make 400 or 425 whp is pushing it for this turbo ?? and if not can i make that a say 14 psi?

Schister66

you can probably hit 450whp, but you're going to be pushing into the 18-20psi range which on those turbos is getting up into the inefficient range....the exhaust wheel is just not designed to flow more than that...if you want to make more power, you need to get a turbo with a different exhaust wheel at least...

will this turbo do the job? Product Description
COMPRESSOR SPECS:T04S housing

flow: 61 lbs/min 781cfm

.70 A/R housing

60 TRIM wheel

TURBINE SPECS:T3

.63 A/R housing

HIGH FLOW 76 TRIM stg 3 wheel

oil lubricated centersection.

for use with external wastegate.

COMES STANDARD WITH 360 DEGREE THRUST BEARING!!!

supportable of 575whp!

and if so what would this be good for with out pushing it? thank you'll for the help you'll have give me.

sounds like a 60-1 , i plan on using that same spec. turbo to make the same hp your asking about. i have read threads in the past about 60-1 and people are making anywhere from 400 whp to 500 whp with it..

d3vilishSi

would 400whp or 425 be pushing it as well for the turbo i have?

when looking at the compresssor flow. just add a "0" to the end and that will give you a good estimate of what the turbo is capable of making at the flywheel.
example 61lbs/min = 610hp or about 540ish whp..

400whp would not be pushing the turbo hard at all. but it is a pretty weak turbo for your set-up, i would only reccomend that turbo for a stock block.
your set up can handle ALOT more power. sell it and get a t4 61 p-trim

i had my girl friend post this topic for me thank you everyone for all the help and info youve given me.

You have to look at this as a matter of what your bottom end can handle, not JUST "X" boost at "X" psi... Daily driven, 450whp is slightly difficult to handle under daily driven car when in boost, even when suspension is used. Whether you use the 60-1 wheel or higher, you still have to address the exhxaust wheel issue. The compressor wheel may be able to provide the power, but the turbine wheel has to have a particular flow rating so as not to perform as much "work", in order to do its job. Give me a shout... I may have a solution for you.
