1.8 bar I believe. I'll have another dyno run this Saturday with a wideband O2 reading as well. It'll be done on a Dynojet this time.

Ah, I didn't see that it was a mustang. Thats a really good # for a mustang dyno.

I will be ordering a turbo when I get back from vacation on the 4th, can you tell me what other mods the car has? IC, LW flywheel, UD pully, cams, etc?

Thanks

I never got the sheet scanned but it will have to wait regardless.

I did 604 WHP corrected (624 uncorrected) at 1.8 bar but I was missing badly at about 4500 RPMS (i'm probably going to replace coil packs and plugs). To top it off, I'm now having problems holding boost above 1.3-1.4 bar so I'm replacing my POS HKS Racing BOV with a Racing BOV II. We'll see if that fixes the problem. I'll post when I have a solid dyno run.

Why is it that HKS themselves said that the part of the RPS Turbo kit called HKS Racing BOV isn't a true BOV and in fact shouldn't be used for anything boosting more than 18 PSI? They said I was wasting my time using the part I have.

I'm also going to see if my wastegate has some issues as well.

Just curious what you guys are using for wastegates? I just ordered a Dual BB T66 P-Trim with 82 A/R from Innovative.

Thanks :D

turbonetics racegate is probably the most popular. Mine was acting very inconsistent after installation, so I bought an HKS GT, which is considered the best. But now my racegate is behaving itself for the time being.

My Greddy Type R wastegate holds boost great along with my Profec B. This was their big one, but now they make a TYpe C, which I believe is their largest, similar to the HKS GT.

TTA89: let us know the spooling characteristics and power of your new turbo. Thanks

Well its for my Turbo T/A so I dont think the power or spool will really relate to a Supra but if you want to know I'll still share with ya :D I'm planning on running a 2800-3000 stall so it should spool awesome in my car, I hope ;)

Im not looking to go crazy, I want 128mph trap speeds so I think I need 602hp at the motor. That shouldnt be a big deal with this turbo.

It better pull like crazy on the top for the price this thing costs :eek: My last turbo cost $675 bucks lol
