What intake are you running? I have 123 now, wondering if I should go bigger?
Simple I want over 1000rwhp without leaning on it. The TVS2650 is a bad unit and will easily support 1000rwhp on a built GT500.
It’s more than enough for 99% of Shelby owners. I’m confident my combo will make close to 1100rwhp with the 2650 but I know I’ll have to lean on it hard vs the bigger blower making it with less stress.
Hopefully I’m making the right call.

I think Gen 3 3.4 is better choice for your combo if 1100 is the goal. Just my .02.
3.4/4.0 same height and case just slightly longer.
Both get Gen 3 rotors, so $500 no brainer to me to go 4.0 if same fitment.
Please let me know if I'm missing something there.

That is the same logic I got from talking to the tech. at Whipple. I am just not sure as it is a street car first. 2650 or Whipple 4.0. I know the 4.0 will exceed 1000rwhp easier but I like the instant torque, reliability and hood clearance with the 2650. Life is full of hard choices!
I'm going to run the 123mm also.
I have a 127mm and 148mm. VMP is currently tuning for 148mm.
I believe you have a CJ crank so limited to ~7200. You have a good motor combo so spinning a 3.4 harder will have a broader power band with both pullied to make ~1100whp on good fuel.
Thanks man.
I talked to Whipple as did my tuner whose been a Whipple dealer for years and they recommended the 4.0L
I believe some of the Super Snakes had the 4.0 and in the future I may build the spare block/heads for more or just reliability.
For now I'll cross my fingers with the dual keyed JDM prepped CJ crank.
It's hard to spend the cash and not go $500 more for a 4.0 that fits the same physical space.
So, has anyone seen any first hand knowledge of the VMP 173 TBs?

Yea and when I talked to KB they said the same thing go 3.6 for your power/et goals. Bigger is not always better though. Anyways what pulley combo will you be running on the 4.0? Curious to see how it does as you made solid power with the 2.3.
I think some of you are going off topic about KB and high jacking this thread.
Anyone have this Gen3 blower yet or have it installed? When do they plan on putting the VMP TB on the market?

I haven’t heard of many GT500s with it yet.
Unfortunately the kits I’ve seen (Coyote and GT500) had the smaller 160 TB.
Many of the early buyers wanting big power will want the big 173mm TB

Got a Gen 3 / 173mm TB / big JLT car we’re finishing up now at the shop. Will post details / pics when finished
I started my install this past weekend, but had too many things to do, so I will finish up this weekend, and report how the 2650 does. Stay tuned.
Interested to see real world results. I'm going to finally ditch my gen I VMP this winter and go Gen 3. I've made 775/830trq through some radials on the gen I. With rods and pistons, I'm gonna be looking for 9-950 with the 2650.
For those considering the 4.0 Whipple, it takes a lot of engine power to crank that big blower. I've seen quite a few TVS cars walk away from the big blower cars on the street, if that matters to you.

Yes that would be great! very interested to see how the 173 performs.
Im interested to see flow numbers on the VMP 173mm. Ive got a Whipple 170mm oval monoblade and that ****er flows a ton of air (2000+ cfm). Its less than ideal for street driving (tip in feels doggish), but you mash that gas and she goes into boost... hold the F on! And that's with a shitty home ported M122 and off road H pipe lol.
Interested to see if the longer but thinner VMP unit has better street manners than the shorter but fatter Whipple.
