a6t8vw Posted February 14, 2008 Share Posted February 14, 2008 Hey guys im wondering what the biggest front mount intercooler you can fit in front of the S30? Seems the 24"x12"x3" style is the biggest and easyer one to install? What size is the one your running ? thanks, Andy Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted February 15, 2008 Share Posted February 15, 2008 umm... biggest isn't really best. You have to count pressure loss and what you are willing to take in return for cool air. I suggest getting the book "Maximum boost" if you already haven't. Quote Link to comment Share on other sites More sharing options...
Sparky Posted February 15, 2008 Share Posted February 15, 2008 The biggest you could fit is around 26" x 16" x ? core 36" wide with end tanks. now this would be sitting past the very ends of the front frame rails so you would have to lose the hood hinge torsion springs. it would also sit below your standard air damn opening. The thickness is a ? because that all just depends...you could probably fit a 5" core with those other dimensions. but why? it was already mentioned that biggest isn't the best. over all efficiency and pressure loss across the core should be calculated as well as your HP goals and the type of driving you will be doing/ what the car is going to be used for. The first 12" or so of the intercooler is where you see the most efficiency*, anything after that is just more cooling tubes before you cram the air into the intake manifold = pressure/flow loss. *IIRC if you want a giant intercooler just because, I will sell you mine.

a6t8vw Posted February 16, 2008 Author Share Posted February 16, 2008 im going for 600 crank HP, what size do you recomend? Quote Link to comment Share on other sites More sharing options...

The core size looks big but it is split and a dual pass. It would have a pretty high pressure drop compared to a single pass of the same size. This would have the least pressure drop. I would of run one if they were 4" thick. http://cgi.ebay.com/ebaymotors/1-Side-Turbo-Intercooler-Grand-National-GN-Mustang_W0QQitemZ370024566558QQcmdZViewItem?hash=item370024566558 I run a 24x12x4, car doesn't get hot when it's over 100* and the a/c is on. Bigger is better as far as cooling. Quote Link to comment Share on other sites More sharing options...

Bigger is better as far as cooling. oh well, I got one at a good price. I asked around about the XSPOWER one and people didn't seem to recommend it at the time. Ad claims .2-.5psi pressure drop @15psi which is all i would be running so i couldnt imagine it could be that bad. Quote Link to comment Share on other sites More sharing options...
Clifton Posted February 23, 2008 Share Posted February 23, 2008 Ad claims .2-.5psi pressure drop @15psi which is all i would be running so i couldnt imagine it could be that bad. This could be true assuming they tested which I doubt. They also don't say at what cfm the results are at, to just say 15 psi is very misleading. A 250 hp engine running 15 psi doesn't use nearly as much air as a 600 hp engine running 15 psi. Quote Link to comment Share on other sites More sharing options...
myplasticegg Posted February 23, 2008 Share Posted February 23, 2008 stay with the vertical core side by side end tanks. Very little pressure drop and the plumbing tends to stay shorter. Treadstone makes some affordable ones in 3 sizes... The medium one fits in the Z without any issues, the large one is about as big as you can get for a Z.

I guess only way to see is to test it and find out Quote Link to comment Share on other sites More sharing options...
a6t8vw Posted February 23, 2008 Author Share Posted February 23, 2008 Thanks for all the info guys but im going to use the 24x12x3" crossflow, seems to make for an ez install... like big phil! but i will have mine against the core support. Does anyone have any pic's of a intercooler behind a type-3 airdamn? $100 shipped ebay Quote Link to comment Share on other sites More sharing options...
ktm Posted February 23, 2008 Share Posted February 23, 2008 24x12x3 also with Kaminari airdam, which the Type 3 is based on. Quote Link to comment Share on other sites More sharing options...

I think so, 3.5" thick bar and plate design, 1 psi pressure drop at 76.5 lb/min (1000 CFM). I just don't think it would fit that easy. Just the core is 26" long and it is only 10.5" high. Sparky said 26" is about the max length including end-tanks. I'd keep looking for something narrower with a 14" or 16" height. [Edit: In general, height is more important than length for a horizontal core IC, and vice-versa for a vertical core. It's a balancing act of efficiency versus pressure drop.] Quote Link to comment Share on other sites More sharing options...

This would have half the pressure drop. I don't know if a lower pressure drop or longer tubes makes more power though. http://cgi.ebay.com/ebaymotors/TURBO-INTERCOOLER-22x6x3-Supra-7MGTE-1JZGTE-Mustang_W0QQitemZ270217548469QQcmdZViewItem?hash=item270217548469 Quote Link to comment Share on other sites More sharing options...
hughdogz Posted March 9, 2008 Share Posted March 9, 2008 It would be cool to see a convective heat transfer CFD on one like Clifton linked compared to a horizontal. If it isn't internally baffled the flow is really low for the first half of the tubes compared to the second half. Flow exponentially increases along the core length. I like the vertical core with long end-tanks design for our Z's. Shorter length charge-pipe tubing to run, and less pressure drop for sure. I just don't know if it has comparable efficiency, or if it is more easily heat-soaked than a horizontal core. Consider that a 24x12" horizontal core has 288 in^2 frontal area wheras the vertical core one posted has ~152 in^2 (22.5x6.75"). That's 90% more frontal area for the horizontal.

a6t8vw Posted March 12, 2008 Author Share Posted March 12, 2008 ^^ nice man, soon as i finish my T-56 install i can start the turbo stuff. of course its costing more $$ and taking longer as always... Quote Link to comment Share on other sites More sharing options...
jc052685 Posted March 16, 2008 Share Posted March 16, 2008 mine is a little overboard Quote Link to comment Share on other sites More sharing options...
