second thoughts
I am having second thoughts on what turbo to get. The choice is between a 57trim t3/t4 60/40 and a 57 trim 60/63. My Motor is a stock LS (keeping stock rev limit 7200rpm). Since ive never ridden or owned a boosted car, i don't quite understand what people are talking about when they say a .48 turbo will "fall off" up top. I know i will have push more boost to see the same power level on the .48, but are the charastics of these two turbos soooo different that i will notice a change at different rpms. since im keeping my 7200rpm will it even matter? I want a .48 turbo b/c of tq numbers it just makes more sense b/c it is a more usuable power band for a stock LS with a stock rev limit. what do you guys think? max power is 300whp. Thanks for understanding my beautiful delema.

ok, since no body is responding let me make this a lil bit easier.
Two identical tegs are in a race from 0-150mph. Both tegs are rated at 300whp!!!!! Same wheels, same tires, same interior.... exact same setup except one of the tegs has a .48 t3/t4 57 trim while the other has a .63 t3.t4 57 trim.
Who comes out on top. please keep in mind that the only difference in the two cars is their respective turbos and of coarse boost levels. Tuning, and everything else is the same.
Oh and btw, they are both the same color

Hey guys, if this question is too hard for you "super tecs" to handle, just come clean and say so. No need for the super fustrating comments. And dont tell me to read a compressor map b/c this is not "theoritical"...this is real life. So tell me which setup will go from point A-B the fastest.

Re: (Whiteintegra)
look man, if the two cars are the same with the same hp then it would be a tie. that is a no brainer. now the bigger the hot side the more top end it will have. also keep in mind the bigger the hot side the more lag too. but between those two turbos, the lag will not be that much so get the .63 and not the .48.

Heard of area under the curve? Why do you think a turbo car at 300 WHP is so much smaller than a centrifugal blower at 300 WHP?

Also, the .63 turbos tend to to have as much tq as the .48s
But the .48 will have more area under the whp AND tq side b/c it spools up faster and tends to hold boost until 7800rpm. Since im keeping my stock redline, wouldnt a .48 be faster than a .63!?!?!?
where are the turbo gods when you need them!!!

yes I have, but like i said before there is not much difference between these two turbos. a centrifugal sc and turbo are way different stories that are irrelavent in this situation. so befoore you go and try your hardest to prove somebody wrong, watch what you are trying to say. ok? thanks for making me respond back.
by the way, good choice with the .63. You will be pleased.

This part is right. Its all in the math. The smaller turbine housing should allow for faster spool which means more power earlier and equal power when all is said and done means greater total are under the curve. It does seem for this hp level that the .48 a/r housing would be the better choice as niether housings would likely choke the turbine at ~300whp. He is looking for response. Many will go with the larger housing because they don't want to be cruizing around town under boost, because they may want help with traction or because they do not want to limit the top end hp of the turbo. He has already stated that he wanted "usable power" at a max of 300whp. The .48 a/r would be the better choice imho. That being said, the .63 a/r housing probably isn't gonna be horrible either. But he did ask for the best housing for his situation.
To answer the og question................
If the turbine housing is the only variable, then my guess would be that the .48 a/r housing would do a bit better. But then again this is like I said......a best guess based on my likely flawed logic. GL.

Im sure you'll be fine with that one. It also gives you more breathing room later if you decide to turn up the boost. And you probably will.
