Some dyno numbers on my project TT Cobra

**Twin01cobra** · 08-18-2007, 03:26 PM

Car was on the dyno last night for a couple pulls, at 14#'s of boost and 14* of timing the car made 580rwhp, 606rwtq, these numbers were made being very conservative. It's not done and will go back on the dyno again tomorrow for more tuning with timing and boost being increased. I'll have some more numbers tomorrow night.

Good Luck. What's your max boost gonna be?

Not sure what the max boost is going to be but we are going to get as much out of the car and still be safe. Also while on the dyno on a 4th gear pull it went 173mph

Just got off the phone with Terry and it's now at 634rwhp 659rwtq at 17#'s of boost and 16* of timing on pump gas. He is going to turn up the boost a little and do a 50/50 mix so I will have some final#'s. Things are going well and the car should be ready to hit the streets this week.

Car just made 700rwhp 764rwtq at 4800rpm's but due to the stock fuel rails he had to stop the run, so he found the limit of the rails. I guess my next buy is fuel rails.

I here ya Bob, I see a tranny in my future as well. I will not run that power level all the time as it will do more harm than good on the street, but it is a nice option to have

. These turbos really impress me.

**Twin01cobra** · 08-19-2007, 10:14 PM

Final #'s are in, 670rwhp 700rwtq at 20#'s of boost

**gmkillr** · 08-20-2007, 12:16 AM

Twin 61mm turbos
44mm wastegates
50mm blowoff valve
Dual GT pumps with upgraded fuel line
83# high impedance injectors
SCT big air 3000
Forged shortblock
31 spline mosers with spool and 3:27's
AJ k-member with coilovers
Spec stage 3 clutch
Plus a lot more that I can't think of right now

Once the fuel rais and ignition are upgraded we will turn the boost up and see what it can really do.

**Rio94gt** · 08-20-2007, 04:05 AM

That is insane. Awsome numbers. Turbos really are the shit.

**SonofaBish** · 08-20-2007, 07:54 AM

wow very nice!!! i fully expect to be right there with you.... my car was supposed to dyno today or tomorrow, but it looks like the weather is going to ruin my plans for a couple days

**9secmach1** · 08-20-2007, 06:11 PM

John, let me be the first to tell you your trunk is not very comfortable.:D Hard to believe a lil ol mod motor with stock heads, cams, intake, and 281 cubes can make so much horsepower and tq on such lil boost.
