bullseye gt30r...what A/R ?

[dan2288]

you can either get it in a .48 or .63 turbine housing. What would the differnece between the two be ? Which would you recomend for a dd ?

.48 will spool sooner and have less top end.

.63 will spool a little later and have a little more top end.

There are even more variables. This is a very broad question but thats the general idea.

 

[dan2288]

what other variables are there ? Do you think a .48 is good in a gt30r ?

"Bullseye's turbine housing is a .58 to .63 A/R Turbine Housing depending on what turbine wheel you put it in, i'm not totally sure which one it would be with a GT30R turbine wheel, but it's right around there."

Info ^^^ from Cragger who used to work at SBR.

You can look into PTE's GT3076RLE which is offered in 0.48 turbine A/R for fast spool but with cams, etc you might make the turbo suffocate.

I suggest the bullseye since it has a ~.60 A/R turbine housing, SBRs GT3076 turbo or FP3052.

Check out a thread called "Turbo Education thread" it has a lot of good info in it. It should be under FAQ. EDIT: Here's the link. http://www.dsmtuners.com/forums/showthread.php?t=199534

My next turbo I think will be a bullseye gt30r.
