View Full Version : Rotary Extreme v-mounts 3rd gen

05-17-2009, 07:38 PM

Hey everyone,

The regular v-mount is now the small v-mount set-up that will be more then enough for any small single turbo or twin turbo set-up, good for upto 400 whp and can support Time Attack type events with ease. BNR or 99 spec turbos included.

The monster v-mount will be reclassified as the large v-mount and is best when supporting any application making more then 500 whp. The monster v-mount is best for a drag set-up.

The new medium v-mount will be the best all around. This v-mount fills the gap between the small and large v-mount kit. It will support 400 to 475 whp all day long in drift and time attack events.

These new kits are designed from years of use and feed back from Rotary Extreme v-mount customers and research in the field of autosports.

The new kits come with all new brackets and hardware, new beefy tow hooks, more space for your modified a/c lines, new oil cooler to replace the power steering cooler line, all wires and connections needed to extend the radiator fans, samco hoses, t-bolt clamps and carbon diffuser in between the radiator and Inter-cooler to reduce turbulance and aid in more straightend airflow to the cores.

All kits are very close in price and are priced as complete kits. You will need to figure out which application is best for your set-up.

The new kits will be updated on the site once fully completed with the new pricing in September 09. <--- yes pushed back. sorry.

Then I will be working on the same v-mount set-up for the 2nd gen RX-7. I will have two kits, one low power and one high power. The low power kit will be for cars making 350whp and less. The high power will be for 350 whp and more.

The low power will be more then enough for a modified stock turbo 2nd gen. If you go to a larger turbo, your gonna want the high power v-mount set-up.

Catch ya guys later, Ben

when do you expect to update the website w/ new info? or is it already up? (didn't see the medium v-mount)

07-08-2009, 08:02 AM
I will update the website as soon as the track mount is fitted on Calvin Wans car. He already has a power steering oil cooler so he will not have the one supplied in the kit. If you are going to keep your AC, you will still get the center CF vertical divider. If you are not going to use AC, I will have an optional stepped CF piece that will aid the air flow through the radiator core.

All three kits are going to be released in about 2 months with the new pricing.

Thanks, Ben

It looks like the new kits will be around 2500 for everything you will need.

I can do group buys if I see more then 5 people interested. It does not have to be 5 of the small mount or 5 of the monster mount, it can be mixed up. Just need 5 people interested then I will open a group buy.

Just an update, For anyone in the US, lower 48 states..

Who ever buys a vmount kit from me at retail price in California, talk to me first to save tax from buying it from the paypal link. Also, in Cali, the shipping is around 100.

If your in Cali, for 350 plus the retail price of the vmount I will install it on your car.

For all other states, for the right price I will come to you with the kit.

Plane fares are getting cheap...lol

Offer good until the end of 2009.

P.s. This does not apply to group buys, sorry guys.

Here are some pics of the track vmount set-up. Beefy 1/4 ss towhooks. Large garret core 20x10x3. Modified 2 pass koyo radiator. Power steering oil cooler. New front frame replacement bar that has brackets to support the back of the radiator. The kit will come with hose techniques silicone hoses for the I/C and radiator. Come with pre-drilled holes and hardware to mount your A/C condinsor.

Optional parts listed below.

Battery relocation is required and we have a kit for that.

Carbon fiber duct in between the radiator and I/C

Sard 75 degree celcius themostat.

Light Polishing of all pieces in the kit. The photos show the finish of the light polish.

These photos are early release photos so you can get an idea of what the kit looks like.

Looking good man, glad to see you working on new things for the rotaries. Impressive for sure! Keep it up, any new projects coming up?

08-27-2009, 04:32 PM
Only new project, the big one anyways, is my Eaton TVS s/c kit for the RX8. Its the s/c from the new ZR1 vette. Once its working on the RX8 I'm going to make it work for an FD. I know some poeple might think its a joke or thats it's stupid, but I want to make it work for myself and see what kind of results I will get.

08-27-2009, 04:42 PM
cool, keep us posted. Want to see the power it makes over the turbo cars.

08-27-2009, 04:53 PM
The idea behind the s/c is not to make more power then turbo, the idea is to make the car as a whole more responsive and predictable. I am targeting Time Attack and togue style racing. Tunning will be easier and the whole kit will be half the price of going single turbo with its supporting mods. There will be less heat and you will have 20b n/a performance from your s/c 13b 2 rotor. Figure that less then 10k would include the s/c, vmount and fuel system.

I originaly wanted to make a 20b n/a fc track car. But after cost assesment. An s/c 13b fd is easier to tune (more predictable) and way more affordable to support through a race season.

Just my thoughts.

08-27-2009, 04:57 PM
well, maybe I worded it wrong....I can't wait to see how the power curve differs in the SC setup vs the turbo setup. I'm under the impression the SC will make more low-end power than a turbo.

Will you be doing the SC on an REW block? Franken-motor?

Is the 20B's cost what kept you away from doing the NA FC?

08-27-2009, 10:20 PM
whoa dude, how the hell did I just get control of your post.....WTFeathers????

ok, fixed it...lol

08-27-2009, 11:13 PM
haha, you're a Mod in your section so you hit "edit" instead of "quote" that's an invasion of privacy!!! :rofl:

Sounds like a good project! 10K for a whole setup sounds pretty reasonable too, you'd spend almost that much to mod a rotary for 300-350hp anyways.

The Eaton TVS will make power all the way to redline. I am also curious at the same psi the comparision to the two. A T-78 at 11psi makes about 330whp and 250lbtq. Atleast mine did. For the fd I'm going with a ported rew motor and the S/C. No crazy switching of parts between motors. I'm doing it to see a realistic cost assesment for racing on a acceptable budget.

Is the 20B's cost what kept you away from doing the NA FC?

NOPE. For buying an FD with a blown motor, then rebuilding the motor and throwing on the s/c kit and sespension pieces. Its about the same as buying a cheap fc and 20b, then rebuilding the 20b for n/a and getting suspension pieces. Both set-ups will run about 20k when done for everything. The difference is the FD set-up is way easier to maintain and its a better starting point.

I still want a nice anniversary fc to cruise around, even if its stock on some sweet rims.

Well, only time will tell. It will be nice to just do it and see the results.

haha, i think we're both messing with it now. :lol: fun times.

Oh man, I can totally see how you can put someone in boiling water with this feature.

I can feel the horns growing out of my head already...lol

08-28-2009, 01:28 PM
haha, it takes some getting used to but just remember that "Edit" is where "Quote" normally is. We seriously derailed this thread. Feel free to delete all these commentary posts afterwards too.


08-28-2009, 07:23 PM
LOL, I like it, it shows character.

08-30-2009, 04:52 PM
So an update.

Drag vmount for cars with 500+whp upto 785 rated is $2500.

Time Attack / Togue vmount for cars with 350 up to 500 max whp (for track use) is $2400.

Twin Turbo vmount is good for any twin turbo set-up including 99 twins and BNR stage 3 twin turbos. Good for cars up to 375whp in track use. $2200.

Basic ducting for all three kits is 100 extra for the drag and track kits. 150 extra for the twin turbo kit.

Carbon fiber ducting for all three kits is 250 extra for the drag and track kits. 300 extra for the twin turbo kit.

All the ratings are for constant whp in Track use. The vmounts will support more in drag style 1/4 mile racing.

The twin turbo vmount will support 500 to 600 whp
The time attack / togue vmount will support 600 to 700 whp
The drag vmount will support 785 to 1000 whp

Group buy on these vmounts right now.


09-23-2009, 01:07 PM
i like how you set up your GB. Very cool.

09-25-2009, 07:25 PM
Thanks!!! The FC vmounts should be out 1st quarter next year.

10-18-2009, 07:44 PM
We are closing in on the GB deadline date for the FD vmount kits. Anyone else interested.


10-18-2009, 09:07 PM
Hey Ben,

I've already got the older small VMIC kit, but I want that FUSE BOX mounting tab things! How much for those things?

10-18-2009, 11:04 PM
Thanks!!! The FC vmounts should be out 1st quarter next year.

Im very curious to see these V-mount kits for the FC.... been talking to some funky bastard about them :suspect: and I must say, I'm impressed with the FD kit and want to see your take on the FC

10-22-2009, 06:50 AM

TitaniumTT, nice car and congrats on the car of the month. I can only say I will make the kit so that it will be the last kit you will ever buy. I already know the fan shroud and factory fan set-up will be ditched with a replacement radiator fan combo. I will also use a temp sensor to set the fan on. Hopefully I can find an adjustable one.

I will use garret I/C cores because they are more dense and are more stable because they resist rapid temp changes. True they might have a slight bit more of a presure drop .5lb at most, but the stability at the track more then makes up for this.

I will do research on what radiator, but koyo makes a good one.

I will know more once I dive into it head first next year.

10-24-2009, 03:57 PM
Oh you misunderstood me, I already built my own (more of an HMIC though) I was just complementing you on the FD kit and wanting to see how you tackled the FC. I cut out my support bar, the lower one where the factory oil cooler mounts and built a frame out of AL to mount the rad and the intercooler. Entirely too labor intensive to make it feasible for mass production mainly becuase the support directly replaced the support bar so measuring and building in place is rather critical.

here is a good shot of what I mean

10-26-2009, 05:31 PM

When I said "the last kit you" I meant the last kit "someone"...lol my bad.

Yeah, your kit is way custom, looks tuff. Looks good.

I have not staterd the FC yet, I have looked at it and have my set-up done on paper. But I will be doing the prototype on another memebers car because I do not own an FC, I don't even own an FD anymore :( I will have different IC cores for different power applications.

But what I do know is that I have the resources to get it done and to make it a complete bolt on kit. The fun part in the design, the completed project is so rewarding.
