Well Thank you but I wouldnt say blindly.
I already had the kit done on paper and all my R&D done. I was just going to build it when I had the time. But since ZumSpeedRX7 was willing to take the risk and be the first one to test it I built it for him. The turbo side piping was going to be a little different but when he said he wanted to keep his HKS filters, that was the real hard part. Luckily I have a HKS laying around. I redesigned the turbo side just for those filters. But it was a blessing in disguise, I like how it sits now and my intake kit is the same as the HKS, just with K&N's on the end. I do have an RX7 so that was my jig.
I built the kit on my car, then cleaned it up and shipped it off to him.
But putting the concept of the kit into a working product was the tricky part.
Also I retained all emissions and vacuum line set-up. It is an intensive install, but worth it.
I am at that point to where I fee comfortable in my work with VM kits.
After all, I have 3 for the FC and 4 for the FD... hahahaha
I have a kit for what ever your goal is.

Ben,
I've been looking at your vmount for a year now and think I'm ready to finally get one. Which one do you recommend for me? Right now I have a 12x12x3.5 SMIC with a GT3574 turbo and aquamist water injection. I'm putting out 422 RWHP @ 15psi. I'm planning on upgrading my fuel pump(Denso RP) to a Bosch 044 and tuning for 22psi so that should probably put me in the high 4's low 500 RWHP range. I'm pretty sure my current SMIC won't hack it at 22psi, and am leaning towards your monster VMIC setup, but I'd be interested to hear your recommendation.

I love the aqua mist set-up since Ive watched xlr-8 do his. I will be running this vmount with bnrs since the core is solid.
For you, if your car is going to spend most of its life on the track at 500whp consistently "after" being warmed up and on the go you can go monster.
Alot of people dyno the car from a cool point, but this is not reality at the track. I rate my vm to support a warmed up / hot car already running at the track. So naturally the car will make less power when its hot or the IC is heat soaked.
For this reason If your going to dyno high 4's to 500whp and your car is a street car and weekend warrior for fun and not competition the track vmount is better.
My track vmount is rated at around 600hp normal operating conditions from garrett and they have a note saying that under certain conditions it will support more as in a 1/4 mile drag race.
Anyways, this thread should show you that the single turbo track vmount should be good to go for your goal.

It sounds like your set-up will be very similar to XLR-8
foot note
500 + whp full time track car = monster
500whp max street car/occasional track = track
when I say 500 max, that is 500 max at a safe level, NOT the max capability of the core.
I just like to be on the safe side and I usually recommend a vmount to be used at 70 to 80 percent capability.
Sorry if I sound a little jittered. I work graveyard and Im at the end of my shift, kinda tired…lol

Thanks for the quick response, that is indicative of your customer service. XLR8 does seem to be running a very similar setup. Our turbos are a little different with his being a ball bearing GT35R and mine being a larger hotside GT3574. I have also got a stage 3 IRP ported motor. It will be interesting to see how both these turbos will perform at 20+psi. I do like the larger surface area of the Track Kit which should provide great heat exchange properties while minimizing turbo lag. However, the Monster Kit allows more of a factor of safety at high boost. A little more laggy, but definitely breaths easier.
Since the Track kit is wider (20vs18in), can you still maintain the battery in the engine compartment?

I wanted to throw in my 2 cents.
Well put together kit, great fitment great cooling. Still getting the car back together and on the road but I can already tell a difference over my old SMIC and stock radiator. If you want to keep the stock twins and up the boost this is a great solution.
Also Ben was a pleasure to work with and produces great products.
Edit: Also you can see the intakes that come with the kit as I couldn't re-use my old ones.

Boost response seems damn near instantaneous but I did the V-mount, synaptic DV, and the upgraded solenoids at the same time, so its like a perfect storm of responsiveness mods.
Just remembered, the only fitment issue was that my current strut tower bar didn't clear the new secondary turbo intake pipe, but considering that the kit wasn't built on my car everything else went together great.
