Paolo,
I had a look on your kit on the other thread.
It is just unbelievable, it is really a nice kit.

How do you handle this 1500rwtq ?
<font color="blue">Unfortunately, I never got to run the car on the street with that kind of power because the motor detonated on the dyno due to too hot of a spark plug. The datalog showed there was a range of 10.8 to 11:1 air fuel ratios on that pull. I initially thought it was a minor head gasket that was blown that would be easy to fix. I found out differently when we took it apart. The guy tuning the car tried to make me feel better by pointing out the fact that just about every other tuner out there had blown a motor before making that kind of power and that even though it was not cool to have blown the motor, I was still waaay ahead of the curve. I am having a real motor built by the best engine builder I could think of who, coincidentally, is the first person to run 300+ MPH in a stock bodied car at Bonneville.
I can tell you I ran the car on the street with 10 PSI for about a week before we upped the boost. At 10 PSI, the car made 900 RWHP and almost 1100 RWTQ.
I can tell you that this 900 rwhp was much, much faster than another 522 CI TT Viper also making 900 RWHP I drove produced by another tuner.
Here are a couple of interesting stories:
1.I remember coming back from the dyno after the 9 PSI tuning session and rolling into the throttle in OD with the converter locked. I remember the car started pulling so hard I was sliding back into the seat(the tuner had left the seat all the way back)that my foot was coming away from the gas pedal and I was holding onto the steering wheel for dear life pushing on the accelerator pedal to stay balanced only realizing the car was going faster and faster.... I flexed my foot to get it off the gas pedal and the car started to decelerate releasing me from the back of the seat to be able to reach the pedals again. I am sure I would have noticed the seat was too far back had I still had the 6-speed in there!
2.I was going along the highway at 50 MPH in 1:1(auto tranny) in the middle lane==> a 450 RWHP/510 RWTQ GTS(far left lane) and a supercharged Mustang Cobra(far right lane) with some upgrades blew past me going 100 MPH. I hit it the instant they went by.... I could have smashed into their rear bumpers by the time they were going 150 MPH. No squirrely rear end, just fast as hell!
3. I was rolling into the throttle at 60 MPH in .69 overdrive(slightly taller than viper 5th). I was full throttle by 80 MPH. According to the AEM datalog, I was at full throttle a little over six seconds and the RPM at that point was equivalent to 194 MPH. I did not believe that could be possible, but the RPM gearing charts show it to be the case.</font>
Can you hold this beast down the road under full throttle ?
<font color="blue"> I am sure the boost controller ramping in the boost will allow for the power to be put down in a more useable fashion.
You would be amazed on how much easier and smoother the power comes on with a properly sized exhaust housing and how stable the car is going 200+

You could get easily into the 300mph club at Bonneville but on a regular highway you would scare to dead people.
<font color="blue"> There is a lot more to going 300MPH than just making the power to do so. The build of the engine, size of the turbos, tuning, weight distribution, aerodynamics, tires, wheels, safety equipment and so-on are very important in the car staying on the ground and the engine staying together!</font>
What fuel did you run on ?
<font color="blue">I ran on a mix of C-16 and 110.</font>
And what was the average temperature under your hood ?
<font color="blue"> I did not measure the under the hood temperature, but do remember the coolant temperature was about 213 degrees after the 10 second loaded Mustang dyno pull in overdrive that produced the 1278 RWHP and 1448 RWTQ. The coolant temp went back down to 190 in a matter of a couple of minutes</font>
