JB2 vs Procede 1.47 tonight...
Sorry we don't have a vid, our camera man had to leave early...but here are the results...
Met up with Vq325K We tried from a roll 4 times...3rd gear, 60mph...3 honks...floored it...dead even! no one could pull away from the other...despite the dyno differences, both cars were dead even...we're both stock except for the JB2 and PROcede...oh, but i have a BOV, but i don't think that does anything...next time we'll have a vid up, but expect the same result....

yup, everything he said is true, we went out tonight to do a few runs, i expected to pull a few CL's on him.. could not get him by an inch.. every run was exactly teh same...our cars had the same gas in it, no heat soaking, we tried our best to keep the two cars the same..well, there you have it. $350 for this kind of performance vs $1,430.. what more could you ask for??? and JB2 runs at a lower PSI 11.5 right???

K before you anti-street racers start bashing...i'm posting this at 3:30 in the morning...we didnt see a single car in sight for like 10 miles...
anyways VQ35K...it was fun man, we'll do it again next time with the camera man...to tell you the truth, from my butt dyno i wasn't surprised at the results...JB2 vs procede is a driver's race...

3rd gear, 60mph, so what ever that equals to...4K RPM? Please don't get me wrong, i'm not here to favor JB2 or Bash Procede...i am just there to do comparison runs...

I think it's a bit higher than 4000rpm. Might I suggest doing a 4th gear run, starting at 3000rpm? Starting earlier and using a taller gear will slow things down (longer pull) and better show the difference in area under the power curve. You'll be going quite a bit faster but the test will be more revealing. Judging by 1/4 results, there's a 1-2mph difference in trap speeds between the two which isn't going to be revealed by a 3rd gear pull. Go faster or use a taller gear. Just don't get caught by the fuzz
Doing the test that you guys did (3rd gear, from 4500rpm and up), the PROcede doesn't even reach max boost. This is one of the limitations of the factory vacuum actuated boost control system. On the dyno (starting from a lower rpm) or tested in a higher gear, there is enough loading to coax the system to achieve max desired boost. This is the main reason we rely on direct solenoid control with v2. To get the boost to the desired level, quickly as possible, in every single gear. -shiv |

Not surprising at all. The procede driver that I tested against stated we were exactly even. And we also tried about 3x in a row. Same results. Quite frankly, I was kind of upset I wasn't pulling on him on the roll ons with my JB2 sedan. The instrumented testing showed the fastest times by about .5mph in the qtr mile were from my JB2 sedan, no the Procede coupe. The procede being 1-2mph faster in the trap? Didn't happen in our head to head comparison. So I think from the launch, I am probably quicker. In regards to starting so slow that you are at the lower part of the rpm range, that hardly happens in a racing encounter. Especially with a steptronic, if you stomp on the throttle, you are in the upper rpm ranges instantly.

What's hard to believe, maybe my car is a ringer? I doubt it, and we can rule driver's error out of the equation cause we did it from a roll. Only factor is if Vq35 has a dead hooker in the trunk he's not telling me about... But everything will be clear when i hit the track in november...we rented out the drag strip for the day....
