Is it worth it

I currently have a vmp gen1 with a 2.6 pulley. L&m 77 throttle body with a jlt 127mm cold air intake with a 10% overdrive pulley making 644 to the rear 639 foot pounds. Thinking of buying a gen11r and installing headers to try and vet over 700. What do you guys think? Alot of money for maybe addition 50-70 to the rear.

Those are pretty healthy numbers as is. What fuel are you running?

Im in so cal so 91 0ctane is all i can go without going to e85.

that will be a stretch on 91

Unless you're using octane booster with each tank, I'd say you're stretching the limits of your fuel as it is. Have you data logged your set up? What year vehicle.

Just remember man, come smog time, long tubes will be a big no no. Unless you are one of the lucky few that live in a part of CA where you only have to smog once.

Not sure if they offer it anymore, but VMP used to offer a case swap for TVS superchargers to their Gen 2 standard (non R). Contact BJ and see if they have an extra case laying around. I think the cases alone were like $1500 new. The TVS rotor package is unchanged and a straight swap over.

Its a 07. My boss has a 15 gt with a atage 2 whipple set up. Just trying to give him a run for his money.

I think i could probably sell my gen1 for around 1500 then add the 1500 for the case i could just buy a new one. If im going to buy one, i figure i should just spend the extra 400 to get the r
