Yeah, I'm debating going 4088... and selling my T66.

That was with a leaking head gasket blowing out the spark, and tuning Tps, emanage, vpc issues. It will make more power if tuned right, and no mecahanical isues. IMHO it was very responsive for a 65mm Turbo, with great top end power. The above is black devilsupra's dyno. I made a few passes on the GT4088 with the bad HG but as you can see the ignition was being blown out by the leaking HG. I still have the turbo, but I got a great deal on a gt4067r! If my cams get in in time I will dyno this by months end with my new Wolf V500 thats waiting on the floor.

I will dig up some other passes I made when we were trying to figure out the ignition problem. My 474rwhp and 449torques was at 22psi. I feel with the head gasket issue under control it woud have made over 500 at the boost level!

The a/r was .81 on both. Did you get to4 foot print or t05. T04 exhaust housing must be ordered at time of plcing order, for extra cost.

 

[MK3Brent]

Tooonyyy... you selling the 4088? want a T66? :rofl:

 

[suprahooked]

T4 footprint

With all the right stuff to support yours, you should see 600-650hp

 

[annoyingrob]

Ooooooh, now I can't wait for my GT40-88 with .81 A/R to come! It's been on backorder for a month.

 

[suprarich]

Month????????

 

[MRSUPRA]

What's wrong with the T66?

 

[annoyingrob]

Month????????

PTE said that they have a huge backorder on them from Garrett, and it would take 6-8 weeks to get to me. It's been about 4 so far. It's all good, there's too much snow on the ground right now to be doing any car work anyways.

Hey Brent,
What are the specs on your T66, ball bearing?

I run a 4088 with precision .86 housing. It hits at 4k like a semi truck rear ending you. Im 420ish @ 12psi on my 1jz

Got a dyno yo support this! I was making 430 or so at 15psi untuned in a .040 over bored 3.0 motor!

 

[Ric]

Im at 12psi tuned with perfect a/f ratios on the WB. SARD ecu, SAFC2.

Slips my stock A340e in 2nd and 3rd gear if i let it shift by itself when in boost (have to manual bump it off the throttle and its fine). Full boost in 1st gear at 4k (not bad for the WG slamming open).

Ill have charts soon to support this.
