Just bought a VF-620

Beyond excited! What do I need to know about having a supercharged M3?

haha, great tip! Already on it... My Pilot's are worn out. I have 285's, really hoping I can fit at least 295's...

Be aware of wheel hop. It becomes a big problem when boosted. A combination of subframe and diff bushings seem to eliminate the problem however there is a level of NVH that accompanies this mod. It seems to be more prevalent with DCT vehicles and more geared toward the diff bushings.

Good Luck!

Noise, Vibration, Harshness.

All, for the most part, are subjective so it really depends on your sensitivity level.

Ah, yeah those can be good. Car jumping everywhere when launched is bad though. I'll have to look more into that then...

Congrats on your purchase OP. Let us know if you need anything.

I love my VF620. Just upgraded the pulley to a 650, and use a BPM tune. Insanity. Add an ice chiller and some race gas/E85 and you will be smoking a lot of fast cars.

Does the car need to be tuned for the E85? What ratio are you using it in? Did you not like the VF tune? haha, sorry for all the questions

Also what engine oil do you guys recommend? I was going to go to 0w-40 for the Utah winter...

I think "insanity" is an amazing term that you've chosen. The 650 kit is pure butt in the seat excitement for sure! Glad you like your kit!

No issues with the VF tune, but the BPM tune has launch control and was recommended to me by several friends. For the E85, I just use 3 gallons and top off the rest with 93. Or get some 109 race gas. I use 0W40 all year. Look into 295 tires with a low profile sidewall.
