Here is a dyno of our new valve for twin scroll turbos that will divert all exhaust to one scroll during spool up and then open to allow both to run normally.....
Seriously..... who else innovates like we do??? Seriously?
All, we at SP are VERY pleased to announce the SP 4L80E is completed. I drove the car this morning around town and it is absolutely AMAZING!!!! Sorry, I'm getting carried away with the !!!! I'm speachless on how smooth this setup is, crisp 1-2, 2-3, and 3-4. Downshifts flawlessly, and she scoots....
Ok, so after I got the V3 updated box back, things aren't running the same. Before sending it out, it started, idled and drove perfectly. This is what I've done:
-Hooked up flex fuel sensor
-Wired electrical fan wire to an ouput to control it (except now the fans always stay on, will sort out...

Hi, if Larry or anyone else can help, I just want to make sure I'm wiring my paddle shifters correctly here. If it's wired like in this diagram I made, and going to a pull-UP AN input, it will work, right? Do I need to connect a 5v reference output with, say, a 1k resistor to a point between R1...
So why hasn't Sound Performance built one yet? I'm pretty sure it can be done.......
Are there any other gaskets that I can use in place of the original HKS gaskets for the Super Drager exhaust? It looks like 1 gasket is a 4-bolt and the other is a 2-bolt. Do you have anything in stock that will work?
I saw on ppg's website that you people are authorized dealers.

I purchased an intercooler new from SP and gave it to my fab guy to install on the car with some custom piping. It seems that the intercooler tabs need cut/ modified to make it work with the car. I was a bit concerned that an intercooler of this price point would needed modification. Can you please...
Mariano came to us with a relatively small punch list for his car. Things like an SP intercooler, new piping to match, possibly doing some powdercoating, and maybe some head work. What we ended up with is easily one of the baddest street MKIV Supra builds ever completed by Sound Performance. After...
