Feedback request: JDM front DC2/DBM Circuit race tucked radiator options?
 

Does anybody run a tucked radiator in there turbo road race application? I have been looking at the rywire tucked radiators and just wondering if the are any good. I have a Koyo half size in the integra and it just is not going to cut it. Im leaning towards the tucked radiator because I really don't want to change my turbo set up around to fit a regular full size in it. And If you were able to put a tuck radiator in there did you have to cut the hood latch support? I have a JDM front integra. Thanks

Re: tucked radiator
 

It's difficult to use a tucked radiator on a road race application, due to the clearance of about 4" needed between the radiator and intercooler, to prevent over heating (unless thou have aero underneath that supplements it)

The only examples that might really work other than that are a 1990 VW Scirocco,/Corrado (sp?). Or one from CSF.
I've never experienced a setup where the hood latch required removal.

There is another person (screename "powerless" with his JDM DC2 that was close to using one for his events, but his exhaust manifold (mini-me EQ) allows for it.. I'll see if I can find a link for you.

I plan to use a Griffin 3/4 radiator for my mini-we, single back door Garrett I/C.

That's no surprise. Time to break out the measuring tape, cardboard, and box-cutters to start your mock-up :thumbup:

Re: tucked radiator
 

Just do a full cardboard design. Cardboard end tanks, corrugated cardboard core, full duct tape "welds" =)

An under body air dam may help scoop air to the radiator if you haven't already played with that idea, if clearance becomes an issue in the front to the FMIC. Shouldn't be too hard to mock one up and then cut it out of plastic from Home Depot.

so the radiator has to be 4" from the intercooler? if thats correct a tucked radiator will not wpork

Re: Feedback request: JDM front DC2/DBM Circuit race tucked radiator options?
 

About 2"-4" distance. An air dam will also be beneficial.

so has anybody actually done this with this type of application with success? If so you have any pointers? what worked, what didn't? what did you use for your setup up and any pics so i can get some idea's? Thanks in advance!

Umm. Yeah, no, it is difficult to do.

I suggest finding "powerneedy's" circuit setup. Check h-t via honda-tech.com for details.

boosted94gsr has something similar I'm going to copy when I do mine. He cut out the core support on the bottom (which is hollow) and replaced the cutout section with a piece of (1.5"?) angle to be able to fit the radiator under the rad support.

Re: Feedback request: JDM front DC2/DBM Circuit race tucked radiator options?
 

But Boosted94GS-R is drag racing. You'll easily upset balance of the front end and will need other means to compensate for the change of mass balance when cornering and cone dodging.
I could see that being possible, but I'd avoid it if the purpose is simply for a tucked radiator.

Re: Feedback request: JDM front DC2/DBM Circuit race tucked radiator options?
 

I see. that's not how most people did that when removing the lower support. you simply modified the existing support to work with the Scirocco.. In that case, I think that would be ok to do as an option. So, I recant my previous statement. ;)

Re: Feedback request: JDM front DC2/DBM Circuit race tucked radiator options?
 

Thats the last thing I'd be worried about. Upsetting the front end? I've removed power steering, A/C etc, added on a turbo and all the required accessorizes etc. Moving the radiator back 2-3" is the least of my worries in that sector. I've been fighting cooling issues with my Integra since I first put a Greddy kit on it in 2008 lol. Been through about half a dozen radiators, wrapped everything, propped hood, heat shields, great fan, triple core rad etc. Just not enough capacity with a half size and the airflow is insufficient through the bumper. We're talking 2-3" here right?

Re: Feedback request: JDM front DC2/DBM Circuit race tucked radiator options?
 

Hmm. I've never had that issue entirely with my Koyo/SPAL half-rad combination. I could circuit race with that combination, but I just couldn't stay out as long. So, I wouldn't call the half-rad so much as a problem, as it is a limitation, on what you can do. But highway kills is a bit different than being on the circuit, although in this case, changing the system entirely is the best idea in both racing applications/scenarios. Being a USDM front-end doesn't help things either.

Myself, I'm going to a custom 3 1/4 sized system to work with my 12" high back door Garrett intercooler.

Has anyone ran a chasebay or speed factory tucked radiator with their JDM Front?

Re: Feedback request: JDM front DC2/DBM Circuit race tucked radiator options?
 

you NA or Turbo?

Re: Feedback request: JDM front DC2/DBM Circuit race tucked radiator options?
 

Turbo, inline pro manifold and no space up front to run a proper cooling system the traditional way. I've explored the idea of half radiator but I'm afraid it won't be able to keep up in the summer

Re: Feedback request: JDM front DC2/DBM Circuit race tucked radiator options?
 

I don't have a JDM front but, I used a Mishimoto full size (dual core) and titled it forward under the core support. Chopped/capped the filler neck and added a swirl pot with filler neck. Works great with little to no modification to the chassis.

Do you have any pictures of how you mounted it? Did you relocate the bottom mounting tabs?

Re: Feedback request: JDM front DC2/DBM Circuit race tucked radiator options?
 

interesting. I've run similar with both front ends. I have a JDM front end now , and now changed to a full Koyo radiator with twin SpAL fans. but I did change manifolds too.

the inline pro manifold can easily support a JDM front end

Re: Feedback request: JDM front DC2/DBM Circuit race tucked radiator options?
 

The bottom tabs are factory, the top you can see around the hood latch area (oem hood latch still fits, I just use hood pins) I have a 'C' bracket from the core support to the radiator to mount it up top.

Re: Feedback request: JDM front DC2/DBM Circuit race tucked radiator options?
 

I'll post some pics my dumptube runs in front of the manifold and not offset to the side which kills much needed space. I could get a full radiator to fit but no space for a puller fan.

Is that a heat shield under the inlinepro? Just curious because I'm about to install same manifold soon and never saw a heat shield for one.
