.90 vs 1.0 housing

[mike diesel]

Decided to snag an 87mm turbine wheel and am now trying to decide between a .90 housing or a 1.0 housing.

My end goal is to make 1000 horse on fuel with this turbo, but if the 1.0 housing will be considerably laggier than the .90 housing then i would rather sacrifice some horsepower to gain spool up...

Mark said the 1.0 housing will meet my goals no problem, but i am worried about spool up, my 1055 converter might be a hair tight for the 1.0 housing. What do you guys think? Anyone gone from a .90 housing to a 1.0 housing with an 87 turbine? I also have a 46mm precision wastegate, so if the .90 housing with the gate will get me there or relatively close then i will go that route..

I run a 1.0 housing in my triples with a 1055 and it worked fine.

I have no first hand/seat experience with your setup Mike but if you're going to daily drive it much I would go to a 0.90 for driveability. Again just my option, I'm sure others that have ran one will chime in.

What size are the triples? My turbo is a billet s480, if that makes a difference.

This is my main concern. I don't neccesarily daily drive it, but I will be on the street more than the track so keeping spool up as quick as possible is important.

I went from a 72/83/.90 to a 72/87/1.10 and I don't feel that I lost much driveability

Well this pretty much seals the deal. I'm sticking with the 1.0 housing since I will have plenty of fuel to push it. .90 might choke it trying to push 1000 horse through it.

If you were on stock injectors or cp3 I would recommend the .90 AR but with the amount of fuel you will be burning the 1.0 will do well for you.

wtf??? mike, you have a damn s480!! :rofl:.

Yes that is true but if you hoped in my truck and started driving, you'd never know it was an s480. It drives very nice! I'd like to keep it that way for the most part :spit:

I want my cake and i want to eat it too.

Go with the 1.0. The fuel you have on tap, driving around town won't be bad at all. You probably won't notice a difference in spool up from the old setup and the new 87/1.0

87/1.0 is in the mail

Mark, if your reading, thank you very much!

Well spool up is all personal preference. I'd know it was for sure a large single, that's for sure lol.

That 87 wheel in either housing will be a noticeable difference either way

HI Mike, sorry I didn't get to harass you on the phone but your welcome sir! If you find it too big(you won't) then I'll swap you out of it for the housing of your choice.:thumb:

I appreciate it! That's some customer service right there.

Mark is the man, I have his 2.5 s400 with a 87mm and 1.0 housing. It drives awesome on the street, really like it!
