Wasn't SP57 replaced by SP58? Here is the SP58 description from www.sound-performance.com:
Would you say it's pretty close to this description? Hahaha!
SP58GT, SP61GT ($849) - Utilizing NEW 61mm GT compressor wheels, the SP58GT and SP61GT are designed to spool amazingly fast without sacrificing top end. Created specifically with the stock fuel system of the 4th generation Supra Turbo in mind, the SP58GT/SP61GT can push between 480-660 RWHP depending on exhaust ratio and boost being run. The SP58GT is the slightly smaller and faster spooling of the two due to a reduced exhaust turbine wheel, a perfect match for an automatic Supra, while the SP61GT will make a slight amount more power and is suitable for a 6 Spd.

Jon....thanks for that great write-up. Couldnt wait to get you behind the wheel and get your opinion
I have to say that it has been a few days since that drive and I am still a little disturbed by it. I have never been that fast in a car. That drive was a complete blur....all I can remember with that high speed run was looking at the guages...then looking up at the road wondering why the cars up ahead were stopped.....hey look at the speedo(never seen it there before) looked to me to be over 140....(Jon knows the real speed but he's keeping it hush hush) I couldnt look anymore
Good Luck keeping your license when you get your whip back
Lex400sc.....he wasnt impressed at all in our previous ride. Was have turbo problems then. Dont know if you remember me mentioning the strange vibration and unstable boost. I was only running 12psi then.
Next update when I receive my tranny cooler.

Gazi, the A/F ratios are pretty solid at around 11.1 - 11.5 on the fjo display. I havent received the data logging setup yet. The last story was that they were going with another supplier and they are also backlogged
It will show-up the day after I dyno
The fuel ratios have been solid with the new turbo, but I still want to be sure.

My tranny cooler is in. Its a bit larger than I expected.....better cooling I hope. I still have to get a relay a fuse setup and some fittings before I do the install. I'll try to take some good pics.
On another note...I did a little more fuel tuning on the lower rpm's....3500 - 4000. Leaning it out a couple more percent on the safc helped to speed-up spooling. Now I'm loosing traction in first gear at just above 5krpm InstaSpool

Nice cooler, should have the relay, fuse, and wire you need...i'll try to bring them over to you tomorrow. I assume you'll be using a standard Bosch-style SPDT relay. Instaspool would be a very accurate term...
