Not so good results: Dyno shop it is not!
Story:
I used the shop's "dyno" headers and I questioned the fit to the owner when I was putting these things on. #4 wire was so close to the header it was rediculous. So he gave me some asbestos "condom". I knew this was going to be an issue. The first day of testing we were making some good high torque readings (with the EFI tuner) and I was always questioning the smoke coming from the "condom". The dyno owner kept stating that the "condom" has some oil on it and it is burning off. Well when taking the headers off the next day I noticed this. So it was misfiring and we could not hear it under load. Hence the answer to why it lost torque the next day and it still pulled 630HP at 6100 on 7 cylinders, number 4 plug was black and smelt of raw fuel, the inside of the header was also black and sticky, the other header tubes were nice and clean. All in all the dyno tune still gained over 200HP and torque since we started.
So last year I was running pig rich with 6 lbs of boost and it was still pretty fast and threw you back in the seat as the holeshot was insane. I was only spinning a "A" cut impeller to 5200RPMs. I think with this tune it will feel like more inasane and maybe break the seat this time:D
The most important thing to note is that there is a "safe" tune and I can hammer it without wondering what is going to happen to the motor.
I want to thank Chris at EFI Logics for putting up with me as I was at the point of just calling it off and packing it up with all the issues we had at the dyno.
Thanks again Chris. You will be the first to go for a rip on this thing. Get you goggles ready cause you aint gonna see shit with your eyes watering.
