I finally popped one of my new VMP TVS blowers onto my personal 2007 Red/Silver GT500 and got it on my Dynojet 224xLC. I wanted to swap on a new 15% OD Innovators West lower but did not have time.

My car has a VMP TVS with 2.5" upper, CNC port matched VMP high-flow inlet elbow, VMP 72 TB, 123mm maf, 80lb injectors, 1 7/8 Dynatech LTs, and comp stage 2 cams. Bottom end and heads are stock. I'm running C16 but only going to 24deg on the timing.

We're having some coolish Florida weather this week but nothing like the 50* days from a few weeks ago.

I was expecting over 800, just not this far over 800.





The little 2.3L TVS keeps on going and going to 6500RPM with no sign of HP or boost drop off. My car is down 2-3psi at high RPM due to the cams, you can see it peaks around 21psi in the mid range and drops off to 18psi up top. I'm not making all this power with brute force and boost like some of the big blowers, but rather airflow and efficiency. When we did the cam swap for the December issue of MM&FF the car picked up around 40rwhp peak when compared to similar conditions. I would expect a car with the VMP TVS and similar mods to mine (lower, TB, LTs, race gas) except the cams to still make high side of 700RWHP.

This graph shows downstream air temp during a loaded dyno pull, there is not more than a 10deg spread.



I can't wait to install the 15% OD lower.

I ran the FRPP TVS for 3 years before having my own TVS manufactured. I'm mainly showing the below graph to demonstrate that the TVS keeps on going when pullied for more more boost (VMP TVS exclusively has 2.5 pulley, FRPP TVS is limited to a 2.6 pulley). The main point is the shape of the graph (it's higher at all points, even above 6k), not necessarily the difference since the FRPP TVS run was done back in the summer when it was very hot.

Extremely impressive results Justin!!! WOW...!
I can't do anything with mine until the spring thaw. When I install my VMP TVS I will post my impressions/results.

Nice. I had read rave reviews of that blower when in the Grand Prix world. Everyone was trying to figure out how to mod one to work on the 3.8s. I left before anyone had done it, but I see what all the hype was for.

Wow justin that is hugely impressive, how much power can the stock parts handle?

what is the difference between the vmp tvs and the ford racing tvs besides the pulley difference?

The blower outlet is ported and the unit comes with a ported elbow. The snout is also machined to accept a 2.50 pulley.

I see all the info you've loaded and i've been looking it over. My question is one if the you had continued to pull to 7k would it flatten out or would it still be rising? Also i take it you're still at stock compression.So if your car had a 10 flat CPR with that same setup wouldn't you be able to squeeze more out of it seeing you were already using c16 and this would allow you to run lower boost to reach it not to mention increase overal power? what does the normal VMP TVS gt500 Peak rwhp rpm occur at?
Thanks
Joel and sorry for asking so many questions

This, and also, what would your 'kit' cost, versus a Kenne Belle 3.6 or 4L? I just picked up an '07 GT500, and will be looking to upgrade it with a bigger, more efficient blower. I'd prefer to keep the stock hood, but wouldn't say I'm against that change if need be.
