Fun @ Mason Dixon today with the 4.0
Well, couldn't find a test and tune this weekend so RB6 and I decided to run at the points race at Mason Dixon today. We entered trophy class, which was like 4 cars. LOL. We were really there for time trials from noon to 4pm, and we only managed 2 runs.
Doing what I did at Old Dominion just over a week ago, I lauched the car the same way and got a really good 60ft. As follows:
RB6 (Tony)/Me
On the second run, we didn't get to run each other. He went first and clocked a 12.5 with a 1.9x 60ft. WOW! That is with 331 gears! That car is running real strong.
As for my run. I got a good burn out, started to pre stage adn noticed the car next to me did not prestage yet. So I waited for him and prestaged. I start power braking the car.....
...waiting for the amber lights...no lights. I mean this is after 4 seconds easy, and the car is building boost like crazy.....I look over...he still has not staged. Ugggg. Annoying....so I drop the rpms down, but the car is still building boost....a lot of it. Ambers hit....I launch.
This is probably the hardest launch I ever got off with this car. And it scared the living **** out of me. The car fishtailed like crazy, I thought I would have to get out of it...but recovered and clocked the following:
All in all it was a great time. Tony's car ran real strong! We saw a Z06 there....running low to flat 13's. There was a Cobalt SS. I asked the owner what he ran...he hesitated and said 16's. I was like "shes got more left on the table for sure" and he was like, its not supercharged. We looked at the SS emblems all over the car...and just said ok. Tony and I did compliment him on the interior.
It was a great time. I want to see what I can get out of the car with better air/conditions....but I'm feeling impatient. I think its time to visit PH again and unleash hell. Not sure yet. I know there is more left at this power level despite not besting my 11.75 prior, but that was in 60 degree air. Will have to wait and see. Time slips to follow.
Cheers.

Nice Job Rygen!!
So in general it looks like 13psi is pretty close to 11.7ET pretty much!
How much more boost do you think you need to shave off that .7?
I think you should try a solid 15psi for awhile.. This way its just adding 35-45 more RWHP to your setup and wont take long to master.. What do you think?

Thanks. Actually the car went 11.75 with 13 psi in really good air and track prep at FWC10. That was one of the early am runs, 60 degree air I think.
I already have it dialed in at 15psi right now, though both my 13 and 15psi tunes are detuned a bit due to preserving the transmission. But I talked to Mike yesterday and we are both ready to add the timing back in and risk the stock transmission.
But I know I can get more out of it with the 15psi, but I don't know if I want to wait. I really want 10's, and if I'm going to break this transmission, I want to do it pursuing 10's.
