Question Rx7 Store V Mount Opinions

I have been searching around all the post here about it and no one has posted back with their opinions and performance after they bought the kit . Everyone was interested in it and few bought it but have yet to hear much about it. I am looking to get one soon and was wonder how fitment was and how cool you intake temps and coolant temps(with a/c) are? Looking to hear from people that actually have it and if you like it or not. Thanks alot

To be honest I have only sold a few of them and that is because of short supply on parts that we use. We were converting a Greddy front mount to a vmount but they have discontinued the one we were using so I have had to source other options. I should be able to supply a couple per month.
The nice thing about converting the front mount kit was that it came with all the piping, radiator relocation and power steering cooler relocation. Very simple install as long as you are not running the A/C. Another advantage is its large enough to where you dont need any ducting.

Man i am going to be needing a intercooler kit within the the next month or so i have the money just looking for the right one.

I love to drive my car mainly in the summer(MD gets a little hot in the summer need a/c) but also take it to the track often and want to get into road racing. Your V mount kit looks good but was looking for just a bit smaller so i could fit a small battery and not hack up my car while keeping the a/c. Might go stock mount but asp is trying to find a source for cores and want something better than a hks or greddy stock mount so i might talk to PFS about a kit when i go up there for my build in November. I dont think a fmic is right for me since my car is not always a straight line car and i like to drive it alot so traffic is common and want to keep coolant temps low.

i have this kit and am pleased overall. on my fd, ducting is definately required because of my front bumper. the stock bumper probably would not.

with no ducting and the fans on high, my water temps are perfect. 85c with the fans off, not so good. inake temps stay around 50c cruising non ducted. i do like to drive my fd pretty hard so that is why i say i need ducting for my application.

i will say that the intakes were tough to figure out for the stock twins. this is my custom intakes above. i'm not sure which kits would fit.

here is a shot why i said i need ductingfor my setup.

Cool

Cool. I was seeing like 100c or a little more with the stock set up and when i had the fans on it would be around 89c or so(turned the a/c on so the fan would run but the compressor fuse was out). I have the stock bumper for now but also have a/c i want to keep. anybody with temps with a/c by any chance? Any more opinions?

Uh.. that's REALLY high for what I'd expect from a v-mount. My Greddy SMIC (with stock ducting) kept me at about 35 while cruising this past summer. Boosting pushed up to 45ish (at 12 psi). The only time I'd peak over 50/60 was when I'd run 16-17psi (pre- aquamist).


To the OP: Have you looked into the Pettit Coolcharge SMIC's yet? I hyperlinked the page that has them.

Just a thought.

Yes i actually have looked into them. Prices are a little high which is why when i take my car to PFS i am going to ask about their SMIC's since their prices are good and they have helped me out alot in the past. And heard PFS and the ASP SMIC's where very close performance wise. They also do alot of their own fab work so might have something done. I dont have alot of tools and a place i can make my own setup(wish i could). Like the v mount concept though.

this is also with a non vented hood which i consider a requirement on a v mount setup so it is on my to do list.

as well as these are summer temps in southern california, after all it is an air to air intercooler. what do you want?...the i/c to cool the charger cooler than the ambient air? not possible. c'mon guys, use your heads. so at this stage of my current setup, i am pleased.

Here is a pic of the vmount with the stock bumper. Its a perfect fit.



On the local car here that is running this vmount intake temps are in the low 30's

This is true, a vented hood would help a good deal.

You *do* realize that 50 celcius is about 130(+/-) F, right? With a good V-mount you should have intake temps of a couple degree's over ambient temp while cruising.

That really shouldn't change too much under quick boost either. And it's entirely possible to have lower than ambient intake temps with a V-mount (Water/Meth injection). It all depends on how far you're willing to go to support your setup.

SilverTRD's problem is the fitment of the radiator with his bumper. To much air is going around the radiator and not making it to the intercooler. For a bumper like that you need some sort of ducting which would make a big difference in intake temps.

Jason when will you have more kits in stock? Still looking around and waiting for some more feedback.

actually it's 122 degrees farenheit, so for a non ducted v-mount on a 100+ degree day, im doing pretty good i must say. not to worry though, my ducting is being fabricated already.

Yeah, not to split hairs (easy conversion is to double temp and add 30, or add 15 than double it). If those were the temps from a 35-40 degree day than it's not too shabby =)

I'm getting a v-mount from Re:worx, in the UK, here within the next month. It's big enough that there is no ducting required and claimed track temps are just a couple degree's above ambient. I'm stoked!

i think if i still had the stock bumper, it would be much better as jason stated. but once my ducting is complete, it should be better than the stock as well. plus the use of a vented hood is ideal in a v mount setup. i personally wouldnt go vmic without a vented hood.

make sure you post pics of your re:worx setup when its all finished. thanks

Hello,

I have the Vmount kit from the RX-7store and they installed it (that is my car in the pic Jason posted).

The kit really does cover the whole front opening and then some, so I do not feel the need for ducting - although they did add a little bit of foam at the top of the IC, where it is closest to the front of the car and highest.

The kit really does the job of what I feel a good Vmount design is. Giving rougly equal parts of the intake to the radiator and intercooler. Throughout the summer, I typically saw intake temps of around 30-35 C on the highway in around 80-85 F weather, and I have typically stayed under 30 C when the weather is a bit chillier, say 50-60s. My coolant temps stay very consistent at 85 C or thereabouts. I have not noticed a significant change for coolant temps when I switched from my SMIC and same radiator vs. the new Vmount with the same radiator, but obviously mounted much different.

overall, the RX-7store has the best price on the kit, use quality parts, such as the Koyo radiator and the Greddy IC. The IC is very large for a Vmount, I dont think you could go any larger up front.

It looks to me that it retains the AC? Is this so? Or is that a custom job?
