I would like to hear some first hand experience with a v-mount VS. front mount with relocated koyo/fluidyne.

I am looking at either the RX7Store vmount or the GReddy FMIC with relocating the rad vertical and going to a Koyo.

Now what am I going to use my car for? Daily driving and track days. Single turbo (obviously) and approx 380whp. I will be running Evans NPG and our ambients go from 0-5*c in the winter to 30-38*c in the summer (but I don't drive it when it's that hot).

What kind of AIT's and water temps were you seeing on a v-mount and a FMIC setup?

Stock 93 bumper BTW.

Thanks.

 

If you will be tracking the car stay away from a front mount. Its tough to keep the temps down with a FMIC.

 

Anyone else out there (preferably someone who does not sell the kit I'm asking about, no offense Jason ).

Many people here run FMIC's on their track cars without temp issues. I live in a cold climate and want to know if it's really worth the extra coin to get a V-mount I just want to know how much of a temp difference there will be between the two.

 

Vmount ... nuff said..

 

^ I agree. It is alot easier to keep engine temps down with a v mount because it will not sit right in front of the radiator.

 

w/ a vmount your coolant temps will be lower plus youll have the benefit of shorter, simpler, more direct piping (less lag). plus, v mounts are ultra badass haha

 

ya, ya... guys I know the whole "V-mount is better because it just it" explanation.

I don't think you quite understand what I am looking for here. I want to HEAR is temps from the two setups. FROM people who track their cars with them. Not your personal opinion.

I know in the end, a vmount will be better. I want to see first hand difference between the two so I can make the decision if I can personally justify the extra cost for my car. Unlike a lot of people here I'm not exactly rolling in dough and need to make decisions based on cost and effectiveness.

 

Keep in mind the rest of the car wold has been using FMIC's for a long time without fail. Hell my GTR had a tiny hole n the bumper for airflow, but I had a FMIC, flogged the car on the track and never had issues with water temps.

 

exactly what i was gonna say..... now have you looked into the banzai style FMIC its on thier 20b car i copied it. personally i like it although i have a total of 15 min on it thus far (deployed).

most of the "its hard to keep temps down" talk comes from people running the crappy designed greddy styled setup haveing the piping running over the radiator opening up a massive air leak for your cooling air. a properly ducted setup will cool just fine..... the same as a v-mount not ducted properly will not work any better that an improperly ducted FMIC.

i have not ran a v-mount although to put this issue to rest im tempted to pick up a intercooler core and koyo n-flow to make one just to compare the two.....hmmmmm that wont be till i get back though next year

Hey man......i forgot where I saw it but I saw it somewhere online the contrasting numbers with heat. Vmount vs Front mount when correctly ducted.....V-mount won...first off because shorter piping equals quicker response and spool time. Secondly your not blocking your radiator and heat differed from 4-12 degrees c' at times. And thirdly.... they are easier to keep clean especially when Daily driving. I'd say go with the vmount...it's worth keeping this heated time bombs cool man!. A running motor is worth the extra money in my opinion. Good luck with your decision.

 

To the claim that other cars use of FMIC's is a good indicator that they work just as well....

Other cars do not have the heat sensitivity of the rotary. Other cars do not have the engine bay/oven design that the fd does.

 

^+1

 

v mount ftw. it makes a real statement when u see a v mount set up.

 

who in this thread actually tracks their car? I had a front mount on my FC, never had issues. I have a border racing FMIC on my FD, but I haven't hit the track with it yet, and am now curious if it is going to be an issue. So, and I'll repeat this as it seems to be getting glossed over.

WHO ACTUALLY TRACKS THEIR CARS?

I am wondering if track rats like Fritz Flynn or Howard Coleman find Vmounts so superior on their cars, or if they even bother.

 

Go take a look at the Touge battles over in japan and c what they use....

 

I'm pretty sure those are generally shop built cars that showcase expensive parts in order to convince people to buy them. That said, i did look it up and it appears that the FEED rx7 (which appears to be some sort of champion car) is running a front mount. Another thing to consider is these "touge battles" have more lower speed sections than a track in the US. The video i saw they were barely if ever out of 2nd gear.

so to follow up, i will repeat my previous question:

Who actually tracks their car and has an issue with running a front mount? If so, does even a properly ducted front mount always mean low efficiency?

 

just dont hot lap the **** out of it and you would be fine if you relocated the radiator and ran a fmic. if not just go with a vmount set. not that complicated.

 

Well I plan to run the car in Solo1 (time trials) up in Canada and Timeattack down in the states so it will get the **** hot lapped out of it.

 

I had the Greddy FMIC. I now have a custom V-Mount. I track my car a lot. Search for my experiences with both setups on track in the 3rd gen section in the V-Mount threads. V-Mount rocks and I explained exactly why in my posts.

Even w/o ducting the V-Mount will work much better than a FMIC. Especially the Greddy.

 

Really when it comes down to it, it is all just preference there is advantages and disadvantages and there is alot of mixed information about both. not everyone who has a v-mount set up tracks their car but its more for a statement being said when you pop that hood. in my opinion i would say that if someone was givin a fd with either of the two set-up on it that their would not be much complaining about either.

 

I track my car EXTENSIVELY, basically every other week in the summer. To give you an idea I went through THREE sets of Hoosier R6 tires this year. I'm running over 450 rwhp and I do not turn down the boost at the track. I run a v-mount and it was the best thing I ever did to my car for the track. Intake temps are always below 40*C (a little cooler now that I'm running AI), water temps are always below 99*C even after a full 30 minute session at Mosport. There are also no downsides to running it on the street, AIT's are always cool.

If your going to spend the money, go vmount but it doesn't mean you need to buy a kit. Build something custom to suit your application. That way it looks the way you want it.

I track my 400HP front mount and have never seen temps go above 210. You must have proper ducting to stop air from spilling out and missing the radiator

 

ok, so this is what i'm working with, shown with and without the duct plate thinger

is that "enough" ducting? i am running the stock undertray as well. I'm pretty sure it counts as a front mount still even though it is not at the extreme leading edge.

 

I'm gonna have to check out your car at mosport next time I'm up at powell's place. Car looks good man.




Haven't had a chance to track my car yet with the FMIC (car came with it). But from the floggings I've handed out on the street, it still runs pretty damn cool (koyo n-flow rad).
