id have to agree!...great response in every gear..no complaints.

"Engine work is recommended eventualy although if you take it wasy with the boost you can run it stock motor for quite some time."(sorry, I messed up on the quote I used quick quote and it didn't work the way I thought it would ) If and when I decide to reach hp numbers that high, I would plan to do extensive engine work, but I am mostly curious about any weak links in the driveline. Also by then I would have my wheels (the ones I am looking at would be 18x8) which would add even more stress on the driveline.

Hey Dan...is "Project Phoenix" going to be ready for the East Coast Subaru Shootout?

Compressor Turbine
A/R 0.60 0.82
Inducer 55.0 mm 56.5 mm
Exducer 76.2 mm 53.5 mm


Gods turbo I dont know... there are a whole lot of options for a gt30. What 40 to 60+ comp?

Also, since noone has a gt28 on an sti, we don't know how the responsive it will be.

I dont think its a stretch of the imagination to guess at how responsiveive the gt28 will be on a 2.5L; hell on a 2.0 even a 1.8 its very quite nice.

Dan is using a 52lb/min compressor wheel, on the "520" kit, and a 65 lb/min on the 650 kit.

Supposedly 55 lb/min compressor, or 770 cfm at 60 % efficiency. Fp green according to pdxtuning is 49 lb/min compressor. gt28? much less 35-40lbs possibly.

Are u purposely missing the point. We are comparing the responsiveness of large turbos here. Until now, the fp green was considered very responsive for a large turbo. Definitely much more responsive than the gt30 in this dyno. But as I pointed out earlier, the sr50 w/ a 55lb/min compressor outspools and out responds the green and far outspools the gt30. the gt28 is a mosquito in this comparison toto. If it didn't outspool the sr50 ( which it may not. Time will tell ) I'd be surprised. Just as I would expect the vf39 to outspool the gt28. Let's compare the big boys to the big boys. Apples to apples. And while we're at it, I'd love to see this combo on a mustang or dyno dynamics dyno which is where the serious players are. It's a known fact that taking the wheels and tires off greatly reduces reciprocating mass and artificially inflates hp. The higher the hp, the higher the margin of error. These dynos are fine for tuning, convenient because of their portability but this isn't wheel hp, it's hub hp. Big difference. Silverstipa, not knocking your combo at all. I think it's awesome. The 1/4 mile times will tell.

I couldn't have said it better myself.

Well we read a little lower than Dynojet regardless so I wouldn't say the numbers are necessarily inflated. Oddly, Cobb's Mustang dyno reads very similarly to ours. Project Phoenix will be getting the same block as the one above so hopefully Magnus will be quicker this time. We shall see. It really makes no difference in terms of the dyno type. I think it's mostly in the software on how the numbers stack up against each other.

Please....let's not get into another dyno discussion. We've gone over this over and over again.

Let's just leave it at "Those are nice dyno numbers and we are anxious for track numbers."

Could this have anything to do with Cobb's dyno being at a higher elevation?
