Production intrest: Bolt-up topmount upgrade kit

Hi,

sence i'm not a vendor, mod, donator, etc... i didnt think i should post in the actual product interst section of the fourm.

i've been wondering now for a while why this doesnt exist already?

If there is enough intrest i feel that i could be resoursful enough to get a quality product out for you.

It will be slightly overall bigger surface area (with the core being the same suface area as the whole in the hood and tanks hang off the end a little), have a thicker core, and can be made to have 2" to 2.5" inlet/outlets. the kit will come with all the nessisary couplers, clamps, etc.... you may posibly need a length of hose for the BAC feed.

it could have provisions (flange) for an aftermarket BOV and make use of the greedy thrust tube if nessisary. I plan on having nipples for the BAC but NOT the AWS (BAC if you want to run your AWS you can "T" into the line). I'll keep a tally of these on the OP. Notice!, the less facny stuff on it the CHEAPER it will be.

Honistly if i had to do my car again from stock i would've much rather gone top mount replacement/upgrade rather then making a FMIC setup like i did that took forever to get right (its still not perfect) and the cost even for some one to make it by them selves is still $250+

Pros:

easy to install. (VS front and V mount)

I would guess it would work well with stock and mildly built cars (stock to 350hp+ range).

Cheap to manufacture and distubuit VS frontmount kit

keep very good turbo response. (least amount of piping)

keep the stock scoop functuonal. (no need to spend 600+ on a vented D1 style CF hood when the stocker is aluminium)

Cons:

not good for huge power building (400+)

heat soak @ low speeds

doesnt have the "WOW" factor of a front mount/vmount


I feel i could probly get a quality product like this out for 150-300 bucks depending on what you want.


BOV flange:

Thrust tube compadible:

other provisions/suggestions?:

HKS and ARC made bolt up intercooler upgrades a long time ago. Why don't you do a serious cost estimate first?

Adding to the pro:
Nothing blocking ur radiator.

And fyi, some of us running a larger alternator (commonly use is fd alternator). With stock tmic, I don't see much room left when using fd alt, just be sure urs isn't hitting it.

Once I finish my paint/body work and interior restoration, I'll be doing my upgrades/mods. An upgraded TMIC is on my list of things to do. I don't know if one person constitutes "serious interest", however. Plus, I think I already know how I'm going to go about it and sometimes I enjoy legwork and piecing stuff together.

a other posible part needed may be hood spacers depending on how thick the intercooler core might be, or how thick whoever is buying it may want it.

I would def be interested once I get my car up and running again, and I'm in Michigan so if you need a TII to mock stuff up on I'd gladly let you use my car for a discounted tmic...haha

Sounds like a pretty good idea for those not looking for big numbers & +1 on not blocking the radiator.

+1
My FD alternator barely fits under the OEM TMIC

Another Pro:

Keeping P/S and A/C

Personally I don't care about P/S, but I do like my A/C when it gets to the humid end of summer.

The stock top mount is fine. the problem is the outlet is shitty and the TB elbow is shitty. fix these two things by modifieing the stock unit, and then your god to go by mass producing this.

what about the core thickness limiting it to about 10psi? and if the fins have more suface area it can more effictivly cool the intake charge

i dont know if its limited to 10 psi, but i can say the s5 version vs the s4 version is better. change the outlet and the compression tube and you got a good flowing intercooler that cools when the car is moving.

Where did you get that number at? I've run a stock TMIC well past 10psi. Stupid? Yeah probably, but that was years ago when I wasn't as wise as I am now.

well i've heard that it had vertualy no more efficency over ~10psi(g) ish

a thicker core will help flow and cooling, along with adaptation to use the greedy compresion tube.

And this shouldn't be in the Technical section either...

Post up some of your ideas and designs, maybe... Do a little R&D... But the minute you start talking about this being a "Product" and mass producing and selling things, your thread starts to become advertising.

That's part of starting up a business. You use your free time...

In fact, a cost/benefit analysis is one of the FIRST things you should be doing.

Originally Posted by gear_grinder

So who's car gets to be the guinea pig?
Anyone willing to risk their engine because some welding slag or other debris got left in an intercooler core?


I am involved in TWO separate product/service opportunities involving second gen RX-7's... One addresses a common problem that needs repair on these cars. The other involves building standalone ECUs...

In BOTH cases, the cost/benefit analysis had been done prior to selling or even getting a reading of interest on the forum.

In BOTH cases, money came out of MY (and business partners in the ECU venture) pocket to purchase test cars and to get tools and supplies for the business venture.

And also in BOTH cases, everything was set up BEFORE advertising on the forum.

At the moment, neither is advertised on the forum. The ECU venture is on hiatus due to a supply issue. However the repair venture is ongoing. I don't really need to advertise it, as most already know what that is. Plus, I rely on my customers to advertise.


Here's a suggestion, if I may make one:
Build your product... Get it on YOUR car, running and all...
-Compare it to the stock Top Mount Interwarmer
-Compare with a couple popular aftermarket FMICs.
-Get good hard numbers of inlet and outlet air temps.
-Get good pics of the install process.
-Dyno proof would be a bonus.

Then register for one month of vendor access to gauge your interest. If it flops, go back to your regular account status... You only lost $75 and whatever it took to develop your product.

If successful, however, you could be the next CorkSport or something...


Right now, without an R&D, your claims don't mean much...
How do you know you'll get better turbo response just due to the shorter piping? What if your passages through the core are too small? What if the design of your end tanks introduces turbulence? How do you know you can meet that $350 price tag?
