OK he threw it on the Dyno tonight. He is having serious boost creep.
I guess the Turbonetic wastegates are too small 38 mm. It comes up to 17 psi pretty quick, tried removing the wastegate pipes to see if that would help, same thing.
He did see 750 RWHP@5500 with 12* of timing with 17 psi but shut it down, anyone have some input here???

If its a Turbonetics Deltagate, you are probably right, they have been known to boost spike! Are you running a boost controller to keep it from spiking? If so where is reference signal plumbed to (intake, post IC, pre IC, etc.)? What size spring are you running? (It should be the smallest you have if you are running a boost controller) |

Pretty solid power. It looks like you might have a bottleneck somewhere though. What does your VE graph look like after 6k?

The only problem with twins are that you have to buy double everything and its real hard to work on the car especially plug changes.
Also you are creating twice the heat with 2 turbos. I would prefer on a car like yours a single 88mm that would get the job done.My buddy had an incon twin setup and sold it.He now has a single 76mm and the car is much more reliabe and runs cooler and its a hell of a lot easier to work on. 5.89@123 1/8th mile times with a stick, like 1.60 60ft car is awesome. I have a mp T70 single and made 540rwhp 548rwtq at 9 psi stock blocker 11.1 a/f good luck though if you have any ? pm us thanks. My friend owns Cowl Guage Concepts you should check out his car in there site hell might as well get one of there cowl guages there awesome.

Badass Cobra!
Side question...which front wheel/tire combo are you using? I just put 15x6 Telstars on the front of my 1994 GT, with the most backspacing possible (still the same "frontspacing" as a 15x4 Telstar), with 5/16" spacers to clear the brakes, and they stick out a little past the front fenders. Did you keep your stock SN95 spindles and A-arms, or switch to something else?

Yes it was a custom kit. Flipped TFS-R shorty headers and all stainless piping. I bought it off a local guy and sold it to XJHEAD shortly after.

What intake are you using ? Drop mounts ?
Thanks

Thanks for the pics, sorry about the threadjack.
I still would like the sn-95 fit questions answered though.
Thanks.

I used Energy Suspension Fox mounts for the vert. if I remember correctly. They were the exact same height compared to my factory Vert mounts for a 95' The Hood is a Cervini's Part 111. I am running a Vic JR. The 90' bend was milled on the bottom maybe 3/16 of an inch. Right now it is Very tight with the hood. I did do the Fox Throttle body conversion pre turbo (old set-up). The throttle cable cam just barely clears the valve covers now.. By the way I just made my maiden voyage with the car today. 1/2 tank of E-85 in one hour so I guess I get 2 HPT (hours per tank) The thing is friggen scary 3'rd gear on Interstate at 80 and hammer it spins to 120 in about 1 1/2 seconds. Glad I do not have turbo lag..... That was on regular Nitto's though and it is also chilly here 38* that is about 2* for you Rick..... |

I think I am just out of turbo that is why there is no more power after 5,000 rpm.. |

Twin T61's shouldn't have any trouble making 1100 to the ground even through a T400 man.
