eas | e92 M3 Project - VF620 Supercharger 60-130 Times - Part Deux

Traction is still a problem as the tires are still breaking loose at top of 2nd gear. Once planted, the adrenaline rush from the combination of being pinned into the seat and hearing that awesome exhaust note is something that will never get old.

It's been an exciting couple of weeks for VF. Wiith VAC breaking into the 10s at the dragstrip and our Project M3 moving up 4 places in the 60-130 list, the VF Supercharger systems are serious business.

6s are now the new goal.

So, the 5.23 0-60 is flawed due to insufficient traction? I noted it wasn't measured in any of the other trials.

FI sure can take certain parameters beyond belief. Been there.. Makes for good, clean stupid fun!

Please PM me about costs for such a conversion. Thanks

BTW; Two shifts? 3-4-5 ?

2 shifts starting in 3rd gear, correct.

7.33 time has been beat! http://www.bimmerfest.com/forums/sho...72#post6538772
