I am in the process of making an intercooler kit that works with a vented hood. Someone has this idea before but it never came through. It's going to be a intercooler kit with the inlet duct and also a outlet duct that vents the hot air directly out of the vent on the hood. The spec of the intercooler will be about 13"x17"x3.5" spearco intercooler with stainless steel or aluminum piping. The ducts will be either made of aluminum or fiberglass. The cost of the intercooler kit should be around $2000-2100 with the fiberglass vented hood. Carbon fiber hood is also available. The intercooler kit will only work with the Greddy elbow. My choice of the vented hood will be the Knight Sports copy that me and my friend already made since it has the largest vents compared to all the other aftermarket hoods other than the Scoot one which costs way too much. If you guys show good interest in it, I will go ahead to work on this project. If not, I will abort it just like all the other guys. Let me know what you think of it. Any input is welcome, such as choice of hood style, choice of intercooler core, etc.

I think the fact that no one EVER comes through on these is going to kill your responce. I think if you hade a few already made up it would increase your intrest. I was going to buy one from another member but it looks like it is never going to happen so I think I'll just buy an M2 one.

I want to see what the demand out there is before I get into this project. No one came through because most people do not have all the sources to make it happen. Or it just takes too much time and effort. I have sources to make intercooler and also source to make hoods so it's easier for me to put something together like that. The thing is if they want a intercooler/hood system, they will need to buy both. A lot of people already have an intercooler or an aftermarket hood so I do not expect to sell a lot of the intercooler/hood kit. And also right now there are just too many intercooler kits out there including stock mounts and front mounts. If the demand is not there, making something new probably will only endanger my bank account with those stuff sitting there doing nothing. I have a lot of new ideas but sometimes it's hard to make it happen due to the lack of demand. Before, when I came up with a new idea, I can just go ahead and make it. If I can't sell it to others, at least I can put it on my car. Now my car is pretty much done so if there is no demand first, I can't just jump on it. I guess no one is really interested in such a thing. If you are thinking about getting an intercooler, I can do something like that for you at my cost. Maybe after your car, people will follow.

INTEREST HERE!
Especially if we're going Horizontal Mount on the IC.
Look at this thread regarding HMIC - https://www.rx7club.com/forum/showth...highlight=hmic

Vented hood with the proper duct work around a HMIC, seems perfect.
At any rate, I also emailed you with interest...

thanks for asking.

Nameless

I'd be interested, as long as I dont have to relocate my battery.....but I'd prefer an SMIC, rather than the HMIC. I was thinking about the Knightsports hood from you anyway...so why not get both? hehe.

spyfish007

gee I remember talking about making this one too ... no one had vented hoods back then because they were too expensive ... I wonder what changed?

RotaryKnight

The KnightSports V-mount kit is about 2400 and includes a ron davis radiator. It was designed for thier hood what is the benifit of this over the KS one. The KS one offers better cooling and proven performance.

I need a vented hood and an intercooler so I would be interested for $2000-$2100. The vented hood wouldn't provide better engine cooling because the ducts wouldn't allow engine heat to escape right? Also could you post a pic of the knight sport hood I can't remember what it looks like.

devojrx7

Ok I found the pic on your site so would the 2 small vents be open for engine venting? How much more for carbon fiber $300?

Flexer

I would definatly look into something like that if the proto-type looked good!!! :-)

race1

I would definately be interested in an entire package deal including the carbon fiber hood. When I say whole package i mean everything including the greddy elbow and "properly" fitted turbo piping. as long as I can fit a "small" battery in the engine compartement, I'll be fine. I was ready to buy the cwr kit but after a year of people still waitng for ducts, and the fact it is no longer offered, i've just about given up

rx7tt95

It's really a shame that Duane dropped the ball with the CWR IC's...I was lucky and actually received the duct. The whole package works very well. I was getting ready to make a rear-mounted duct for the IC when I had the little mishap in my 7. I now have one of Chuck's drop-dead-gorgeous KS carbon hoods and I'll be fabbing a rearward duct and route it to one of the vents, leaving the other open.

Just adding a vented hood alone makes quite a difference. Venting it to the rear, as Chuck plans to do, would make it just as effiient as a front mount. Using Thermotech's thin heat barrier film, one could eliminate serious heat soak as well. Seal each duct (front/rear) with a bit of closed cell foam and you'd have quite the setup. Cooling problems associated with front mounts would be eliminated (although none of the tuners in Japan seem to have problems with their FD's) and it would offer lower pressure drop and "fill" time/turbo lag due to the very short piping. I'd definitely have it made out of aluminum piping for weight, and keep it 2.75" OD or under.

I'd be interested to. I started the above mentioned thread and let me tell you something I can't find hardly any info on this type of set up(hortizontal mount intercooler). I really like how it works and looks in the engiine bay. I also hear that the Japanese tuners are statting to use setups like these more and more. Also where can I get info or pics of the KnightSport V-mount kit at? I've not seen it or any pics. Pics would be really nice. Thanks.

I would possible be interested too. Do you have any kind of rough sketches or drawings that would illistrate how this whole system would work?

Gun

I'm not sure about the exact design but to give an idea, I think it would have to look something like the KS V-Mount, just with a vent on the back of the intercooler. Heres a pic I found:




Hope you don't mind rotaryextreme. Just trying to give people an idea of what it will look like.

The Knight Sports V mount is a nice set up. It comes with both the radiator and the intercooler. But I do not think you can keep your A/C with the Knight Sports setup. V mount is great. There a lot of Japanese tuners running those on their race cars but they won't run into the A/C condensor relocation problem. If you guys want to dump the A/C, I can definitely make a V mount. The intercooler will be a Spearco and the radiator I am just going to use the Koyo 2" and modified the end tanks. So now we have two options:

1. horizontal intercooler with duct that works with vented hood
2. V mount raditor and intercooler that works with vented hood but you cannt keep the A/C

I don't know if you guys want to keep the battery or you want to relocate it. It also have to work with the popular intake. If any of you is intersted, email me at rotaryextreme@aol.com with details of your car's current setup on turbo, intake, radiator, y pipe, etc and also about which kind of intercooler you want. I will just make the one that most people are interested in. Thanks.

Chris:

My setup is not even made yet. How do you know the KS one will offer better cooling? How do you compare the KS set up with something that does not exist, YET? It seems like you are here to ruin my project, not to help. I am all about proven performance. When I made the RX-7 Fashion front mount intercooler, I had hard data to back it up. I measure the inlet and outlet temperature with an aircraft quality intercooler gauge. Same thing for this one. When it's done, I will have data to show the intercooler efficiency which is (tempertuare at the inlet - temperature at the outlet / (temperature on the inlet - ambient temperature).

hey Chuck,

here's Yashio Factory's S15....just an idea you can try.

Thank you David. That's exactly what I was talking about. A picture is worth a thousand words.

RotaryKnight

I meant better cooling than what KS found in trying a frount mount on their cars

Gun

Not being able to keep the AC. Would not get the KS V-Mount then. I goota keep the AC man. I also like the HMIC set up better, something like the SR HMIC setup but with a vent, pipes were really short on that one . Especially if I can keep the AC. Battery relocation isn't a problem. Keep us updated and let us know when you have a working prototype. Here is a pic of the SR HMIC:

You can fab up a CRAZY duct if you do one other thing...

Remove power steering & AC....

Relocate your alternator to where the PS used to be...

If you have a single turbo...basically there is nothing on top of the engine...

RotaryKnight

I'll find out from the old US KS rep if the kit retains the AC or not.

Gun

I'm no racer and I thinnk most of us aren't either so I gotta keep the AC and PS. I belive SR website says that with there HMIC setup you have 2" of clearance to the hood. SO I think you could duct it pretty easily. The SR website dyno'd the above car(I believe it's the one)and got 324 RWHP. Here's the write up from SR website:

Project 93' was put on the dynojet. Our Project 93' car is a bone stock 50,000 mile 13B REW engine with all factory emissions including a catalytic converter and even a smog pump. It has our Level III system installed on it. This includes:our new SR horizontal intercooler, SR air box, SR downpipe , SR catback system, and our Power FC . At only 12 PSI boost ,it produced 323 (**corrected )Horsepower with 284 ft. pounds of torque.



What do you guys think?
