Nice! Sounds like all the tunes will be represented. You guys can all take turns getting stomped by Shiv's big single turbo. Are any RB turbo cars going? A big turbo show down would be very interesting.

I know it's been sent out to their alpha group, including yours truly, so I imagine they will post it after they get the thumbs up from everyone.

Is skinrock going to be running Cobb + meth? From what I know Jeef doesnt plan to have Meth..just FBO + Cobb..

Just curious...Im on the waitlist but fat chance they will open it up to any more 335s...Oh well crossing my fingers

He is running FBO Cobb only he had issues with his BMS Meth setup thus he switched to Cobb no Meth.

Damn, these forums need @ mentions, lol. No meth here. I will be running a mix of 100 octane to get it around 93-95 and run Stage 2+FMIC Aggressive.

@ 395rw give or take you might not be competitive with the cars running meth there in the 430-440rw range. Maybe Cobb can get you a race gas/meth map so it's a fair comparison? I've sold a few non-integrated WW meth kits to Cobb owners and while you don't get the full benefit you would with a piggyback it's much better than pump gas alone. It comes with a basic boost switch which you set at around 10psi. Also on the JB4 + meth if the need strikes I'm sure BMS can help you figure out whatever isn't working right with it. There are hundreds of those setups out now running strong.

Maybe, maybe not. But if everyone just ran piggy + meth, it wouldn't be much of a competition imo For me, it's about having a chance to legally do a high speed run. If Jeef doesn't run meth, we should be pretty similar depending on skill.

As far as going back to meth, it's unlikely at this point. I don't doubt it's a great mod for 99% of the people, but I just seemed to have a bout of bad luck. It just wasn't practical for me to do the things necessary to debug it, plus having an Injen intake required a custom install, and it just kept bugging me how it turned out. But now I'm going off topic, I look forward to seeing how the pump vs. meth race progresses. I mean the JB4 numbers are awesome - nearly 500 rwtq. My original goal was to hit 400, just a magic number I wanted to be able to hit, but now it seems like 500-600 is becoming easier and easier every day with everyone's hard work.

406 w/o meth? What boost are you running? Even though you're basically on race gas settings.
