As the title says, I'm looking for a website or something that has intercooler parts. The reason being that my current IC end tanks are not efficient and I want to make a new one. Take a look at the pic to see for yourself...



I'd like to have some end takes similar to this...



...but I'd like to see what else is out there before I commit myself to these, and actually if they could flow a bit smoother than these I'd like that too, maybe have more of an angle where the air enters and exits. If I can't find anything closer to what I need then I'll definitely get these though because they're already leaps and bounds better than what I have now.

I've done google searches and so far I haven't seen anything like what I need, and until I do, it leads me to believe I need to have it made.

Also, I think I read something within the last couple months or so about a new IC core design, has anyone heard anything about that? Supposedly it's better than bar and plate. I could be mistaken, it's been a while since I read it and I'm probably just "remembering" things that don't actually exist haha.

 

you've looked at ATP? http://www.atpturbo.com/mm5/merchant...egory_Code=INT

 

I think that site came up during my search before but I didn't see anything, and I just checked again now and didn't see what I need either, other than maybe a new core to get for the project. Thanks for the link though!

i can definitely recommend bell, they are well priced, precise with all measurements and very good with shipping.

another option is rhdjapan have a full listing of all the greddy endtanks i believe. these are cast units.

 

I was on their website during my search too and I noted that they made custom end tanks but I was looking for ones that are already made, which I hadn't seen on their site. I forgot all about their site though, thanks for reminding me!

I'll check out RHDJapan if I don't find anything at Bell IC. Thanks guys!

If anyone has any other options too, please post up.

 

bell all the way!

 

Well I might be outta luck if I'm looking for something that flows all the CFMs.

IIRC, Howard Coleman said the 500R (I believe the SP model but I don't remember for sure) flows around 1156 CFM. Sean from A-Spec told me he wouldn't go any longer than 18" and when I asked him about the thickness he said it didn't matter as much but I could try dropping down to 3.5" if I wanted. Yeah, that's not gonna happen. And that's fine, since maybe my IC core is about the right size as is. I still don't like those end tanks though.

My current IC, according to my gf who measured it for me since I am away right now, is 25.5x11x4.5. Looking at what Bell has to offer in the 3.5 category first, a core that is 18x11x3.5 only flows 578 CFM, not even close to 1156. So I looked at the next one up, 24x11x3.5, a little more similar to my IC...516 CFM, even less.

Then I looked at 4.5" IC cores, 18x11x4.5 flows 742 CFM. To what I need with a 4.5" I look at 18x17.3x4.5, which flows 1168 CFM. Of course I guess the next size down would be better because I don't want to lose pressure by going to high.

It makes me wonder if they're measurements aren't mixed up. Because it seems like B and C are switched on their site. Am I missing something here? Should I not be looking to go as high as the turbo will flow? It just seems odd.

 

Disregard, Sean told me what size I need to get to maximize response and flow. Now I just need to find some end tanks, I'd like to maybe find some without having to have them specially made if I can.

 

Try getting aholda of Jesse at AFI.

They are located in AZ.

Awesome to deal with and Im sure he will make something up for you.

 

For a horizontal setup like yours, the most efficient end tank is like A and E in the below link:
http://www.bellintercoolers.com/pages/AATank.html

Both Bell and Spearco will make you a custom end tank if they don't already have one that will fit. Use a band saw to remove your old tanks.

Spearco WAVE maybe?

Ok cool, I'll give them a shout. Do they have a website too?

I agree, that would be the most efficient setup and I'd love to be able to use that. Unfortunately with an 18" core it will be testing my limits on width, so I don't think I'll be able to have them coming out the side like that. I'd kinda like to do something like afgmoto did on his, but have them angled up just a bit more because I think my IC is angled down a little more than his. The hard thing for me right now is that I'm deployed again so I can't even look at the car and measure stuff when I need to. My gf measured the IC for me and she said the core alone was 25.5 inches, and even though I think she measured the end tanks and core together, I can't even double check for myself lol. Either way, I'd like to go with a little less height/width for better response and so I can fit a proper size air filter in there finally. Along with a reservoir for an OMP adapter too.

That Spearco might be what I was thinking of, but I'll have to see some pics to be sure. I think the one I was thinking of wasn't quite as advanced as that haha. IIRC all the long, thin plates were curved so air would travel around them and into the fins rather than hitting a flat plate. Does that make sense? It's hard to explain without a pic.

Thanks guys!

Oh btw Evil, I never did get any farther on going Army WO last year. I figured I'd end up hating life so I just stayed where I am haha. Not to mention that I'm getting married when I get back to the US and neither of us want to be away from each other for a year, we can do 4 months though haha.

 

I think I might have found some stuff that should work.

Some of it is kinda expensive and it's in Australia, but some of them are dead on for size.

 

Have you actually tested the pressure drop? While your current end tanks are not the most efficient design, I don't think the other ones you are considering would be much better. Just taking a SWAG, they may gain 0.2 psi @ 14.7 psi boost or somewhere around that amount, but I wouldn't expect a significant difference.

It looks like your main problem is the pulley, not the intercooler width. Pardon my FD ignorance, but can you move it to another location?


Yes, I remember some manufacturers doing that, but the problem is that less turbulence means less cooling. Therefore, you may get more airflow, but at the cost of heat transfer, and I don't recall any documentation showing a significant advantage either way. Therefore, given the greater cost and weight of the curved plate, I think that gives a good indication why you don't see it used very often.

When I was on active duty, one of my neighbors was thinking about putting in for WO flight. I offered to take him to work and show him the job to see if he may like it, but before I had a chance his wife pointed out how often I was gone and that there was no way she was letting him do that, LOL. Normally I would argue, but I had to give her that one. I was stationed with one WO pilot who hadn't been stationed with his family for 5 years. I don't think that is a good life for married people... unless their wife is a bitch and their kids are little hellions, and it worked out great for those guys. It would be nice to retire with a WO's pay, but I know a lot of guys who retired as an E7 and I have never heard any of them complain about their pay.

 

No I haven't tested it, I don't really have the tools for that. I am interested in testing it, but even if I did have the tools I don't think I'm smart enough to break down the information I get. My girl tells me all the time that I'm smart because of the things I do to and for my car, but I keep telling her all I do is read a bunch of threads on here from engineers and ****, they are the smart ones LOL. I have a few ideas here and there but nothing to the extent of their ideas haha. My main concern with swapping the end tanks and going to a smaller core is just getting the quickest response possible from my turbo setup. I guess it would help to get the car tuned on more boost but I figured I'd cover this issue first before getting it tuned. So far I've just been driving the car pretty light, not really getting into boost much. And I started seeing things about more efficient end tanks and figured I'd do some research. Oh, which pulley are you talking about? The crank pulley or what? Got me confused there haha. Oh, are you talking about the idler pulley or the power steering pulley perhaps? I'm not really into moving the PS pulley/system, it's not really worth the work in my eyes haha. I had thought about routing the pipe between the PS pulley and the firewall, but I'd have to move that fuse/relay box, and although I've seen people do this, I'm not sure what they did with that box. That's a thought though, that PS pulley might end up being in the way if I get the other tanks, at least for that side. Did you post the FC engine bay as a good example or bad? Is that yours? That is some incredibly straight piping haha.

I hear you on the IC, I'll stick with the normal design then. Good point. I was probably going to just get the normal design anyway, but I figured I'd ask about that one anyway.

The girl I was talking to last year when I was over here and asking you about being a WO, we ended up getting together and she is the most amazing person I've ever met. And I don't mean to sound all mushy or anything either, she truly is awesome. She's into RX-7s now, she never wants me to miss a meet or any rotary/car event...I can basically do everything I did as a single person but I'm with someone I have fun with too. It's great. And that isn't even getting into all the other reasons she's great. But she is the kind of person that if I wanted to fly and it took me away for that long, she'd want me to do it because it would make me happy and we'd just work through it. I've gone through quite a few a girlfriends and most of them were shitty, and she definitely isn't one. So yeah, I don't think I'd like to do more than a few months at a time away haha. Thanks for your advice last year though!

Oh yeah, we're getting married in St Louis in October when I get back. Maybe we could meet up with you or something.

 

The procedure is to place a pressure sensor (boost gauge) at the intercooler inlet and outlet, and then measure the difference. This will give you the total pressure drop of the end tanks and the core. Your current intercooler core should have about 0.5 psi drop at 10psi boost, and end tanks usually have 0.1 to 0.3 psi drop each. Therefore, you should measure about 0.7 to 1.1psi total drop. Given the typical pressure drop range of end tanks, I don't think yours are going to make a lot of difference. Bends incur about 0.2psi drop per 90deg, so the straighter you can get the plumbing the better.

Your girl is right. It is smart to read up on a subject in order to make a good decision. A stupid person would completely ignore predecessors, physics, and education.

A reduction in the internal volume of the plumbing system will reduce lag due to lessening the area that needs to be pressurized. However, reducing the size of the intercooler core usually also increases the pressure drop, which requires the turbo to spool up more to produce the same amount of manifold pressure, which increases lag. Choose your poison.

It looks like the power steering pulley is blocking the area where most people route the intercooler pipe.

That is a good example, and the car is owned by BLUE TII. Yes, the main advantage of mounting the intercooler in that position is to reduce the plumbing bends. There is also a slight advantage due to natural convection, but it is less of a factor.

Sure, send me PM when we get closer to that date and I will see if I am in town during that time. I usually have at least 3 weeks notice if I am going out of town.

 

That looks like it would be really responsive.... What turbo? sorry if I missed it above...

 

I would really like to do that but I'll have to pick up some tools to do it. I just want to know. In addition to researching it here on the forum I've found some good info on google searches too and gotten some ideas on how to have the best flow possible, I think anyway haha. I was planning on having the piping basically coming out the back like BLUE TIIs, but make the pipe mold into the entire back of the end tank instead of having an instant drop off from the pipe to the tank. Know what I mean? Actually looking at the pic again, I think he has his pretty much the same way I was thinking, I just need to angle mine a little more as it comes off the IC. I really would like to have no drastic angles as it goes from pipe to end tank though, just a smooth flow.

Well, I figure it's alot easier to read up on what others have figured out than try to act like I know HAHA.

See, I still don't understand how that's possible to reduce the size of the core and STILL increase pressure drop. I'm not saying I don't believe you, I just don't understand how that's possible. Isn't there a happy medium? lol This is why I'd love to be an engineer, but again, I'm just not sure I could grasp all that stuff haha.

Yeah I see what you mean. I have 285s up front right now so I'm not sure I could handle getting rid of my PS lol. If I go to a smaller tire again, I'll definitely think about it though.

I kinda figured you posted it as a good example. Well I'll have to have a 90 degree coming right off the turbo regardless, unless I can make the angle a little bigger, either way they won't be as straight as that but I'm definitely shooting for as straight as possible.

OK will do, as long as I can remember. I'd love to bring the FD with me too but I'm not sure that will happen. Every time I go home I want to meet up with other local 7 owners but it never happens .
