Bond on this forum made a little over 380 on the 4088 on leading only. Thats around 420hp with trailing ignition.

I have a "custom" 4088. I have a .94 hot side as opposed to the .96 hot side it comes with standard. Originally it was a 4082 and I upgraded to the 88mm compressor wheel. It's a dry CHRA, oil only, and I'd love to convert it to wet dual BB. I've had no issues with oil temps running this setup but I have two Mocal 25-row coolers and an extra special, secret sauce cooling system. If I remember, I made 390ish on the 4082. Car is currently in pieces going through some changes so no recent numbers. They should be right around 500rwhp at 20-22psi, pump.

That's why I purchase all of my stuff from Sean and A-spec. You get what you pay for

You should elaborate a bit more on your circumstances.

All I can say is wow after reading that. I've lost a lot of respect for more than a few forum members. Tough cookie to chew there signofinfinity. I'm sort of going through something similar now so I can relate. I have a friend from Malta btw...lives here in SW Florida.

Looks like we have pretty similar turbos . I got a GT4088 from A-spec, but with a machined out 0.94 (GT4082) exhaust housing. Havn't dyno'd it yet though.

now why can't i have that compressor with the turbine options of the 4088r?

You can . Talk to Sean at A-Spec. He'll should be able to put a different sized housing on there than what's offered by Garrett.

Hey guys, i have a GT4088 on my car it has a 1.34 A/R hot side, i am on a run in tune at the moment, so i have a 4K limiter, but in third gear it starts making boost at 2200, and has full boost only 11psi buy 3500, even in 1st gear it makes 5-6 psi before the 4 grand limiter, the motor is a S5 13bt is clearanced, dowelled, SCR race port ( i think its just a lardge extend) modded oil galleries etc, i will post up a pic of the dyno sheet when it gets tuned, at the moment it has hardly ne timing and is running relitavly rich, so i think it may even come on boost earlier
