New Intercooler, 56K Death
Picked up a larger intercooler from M2CupCar. With help from Atl93LE it was installed yesterday evening/night. I think we had 4 hours in the endevour.
Original intercooler was a Blackstone Saab 900 unit with the entry and exit on the same side. Pipes were JIM B under the radiator. New intercooler is a 17x6x3 core with great big sand cast end tanks, and pipes now go around the radiator. What I brought to the party: * the intercooler itself * (2) 2.5" 90° couplers * (2) bolts and assorted washers * (2) zip ties cost: $85 What we reused: Original pipes, clamps, couplers, mounting straps We didn't even clean up the old pipes, even though we had access to a blast cabinet :o I have a little work to do still to make the intercooler level (need to take 1" off of 2 different pipes on the cold side). Pics below. Sorry was not smart enough to take pics of the around the radiator pipes when the car was in the air yesterday. http://img151.imageshack.us/img151/9853/39936684be7.jpg http://img252.imageshack.us/img252/4551/91244220zg1.jpg http://img151.imageshack.us/img151/88/29633390hc4.jpg http://img247.imageshack.us/img247/9853/93651675tk6.jpg http://img260.imageshack.us/img260/2684/52238196oz3.jpg http://img260.imageshack.us/img260/8140/30051796qb4.jpg |
Sorry for the big pics, but I wanted anyone who was interested in converting JIM to around the radiator to have a road map. It was really pretty easy, we literally reused all the old stuff, just oriented it differently. The only added coupers were the pair of 90s. We shortened 2 pipes on the hot side, and I still need to shorten 2 pipes on the cold side. So overall, there is probably less volume and less restriction in going around the rad.
The instant Ben & I got the intercooler installed and washed our hands, it started to pour. So we started to put the tools up and the rain stopped. As soon as all the tools were away, it poured again. The drive from my dad's (where we did the work) to my house sucked. It was raining hard, and I had a tough time keeping the nose of the car pointed in the direction I wanted it to go in. It's still wet out today. Hopefully I can get some IAT numbers tomorrow. We also got some tuning time in Ben's 93LE/16G/MS car. I was really impressed at how smooth his 16G brings on power. It felt much more linear than my car. My car is on/off, his was "supercharger-like". |
OK, went out and took (3) complete runs all the way from 1 to 4. They were nearly back to back. Forgot to hit the datalog button until the 3rd run though. Here's what I saw from the computer screen from the 3rd run, comparing to a 1st run with my old intercooler. IAT is down 5-10F. CLT is up 5F. The car pulls harder up top. I got squirrely at the top of 3rd twice. There is no undertray, ducting, or shrouding in place right now.
I am happy, and surprised, at how much better she pulls up top. I assume it is due mainly to less restriction from the turbo to the throttle, but won't discount the fact that less hot air made its way to the motor. |
i bet the cooler air makes a pretty big difference up top, maybe more than you are willing to admit. When that greddy turbo is pushing 14psi at 6-7k rpm i bet its starting to blow a lot of hot air ... anyway, looks pretty nice, but no straight on front grille shots?

I'm betting the higher CLT is 100% due to lack of undertray, nose funnel, or shrouding. |

Looks crooked as shit in the pic, but in reality the pass side is only ~1" lower than the driver side. We didn't have a proper saw to cut the pipes down, plus we just reused the original mounting straps, and it was getting late. So we rolled with it. I don't think a casual passer by would notice that it's crooked. Looks ok in person.
It is definately off center because of the a/c can. Nothing to do about that. And if you think you know the obvious solution--don't go there. |

This must be because I have no undertray or shrouding. |
What's CLT again?
|
coolant temp
|
thanks
|
That's similar to the air temp rise I was seeing (>25c thru multiple gears). I've cut that in half by doubling the IC size. Doesn't this IC have better frontal exposure than the prior? Is the gap behind it to the condenser the same as prior? That coolant temp rise is very minor... perhaps it's the big gap behind it? I followed the school of thought to keep everything sandwiched and sealed up... but I think that also encourages heat soak from the rad when the air isn't flowing through, but helps at speed.
What's the air temp compensation regimen for MS? I know the Link is fairly aggressive as it comes from FM, but nobody every messes with - they just upgrade the IC. |
This IC is has more surface area and more volume than the old. It's wider too. And the runners are taller, considering that my last was 8" tall but the entry and exit were single sided, so that's like 2 x 4" channels.
The last was right against the condensor. This one is a couple inches forward of the condensor. Nothing else was touched. I think just getting an undertray and radiator top plate installed will control temps better. The MS does have compensations for intake temp. It can reduce timing advance and/or reduce boost through active control of the boost solenoid. The user has full control over these features, including the point where they activate and how agressively they cut. But with this bigger IC alone my AIT has gone down 40% through boosted runs. So I'll re install my radiator top plate since that's simple, and deal with the undertray situation after I clean up the install some. |
I really need to get my setup running and my shrouds/undertray together. I'd love to contribute some IAT data to all of this. I'm wondering if mine will show more(or not) on a roadcourse though, since its designed for more aggressive boosting and abuse.
Looks good btw :) |
Off topic but why the bra? My friend ended up getting his front end very scratched by dirt that would catch under it.
|
car was owned previously by a woman who couldn't drive to save her life. so she brought it to maaco for a cheap spray job, and it doesn't look like they did any body or prep work. suffice to say the car looks better with the bra on than without. I don't care if the bra screws up the bumper any further. I have a spare in good shape, and one day the whole thing will get a real repaint.

i spray painted mine.

lol I have rock chips and I dont care.
R-compounds + cars + gravel at the track= battle scars on the nose and bonnet:skid: |
Those pics just helped me alot, thanx Ben

Your top tank looks pretty sick. :(
|
naw it's ok. My last radiator cap started leaking a little because the gasket inside rotted. I replaced the cap and sprayed the rad off with a hose, but didn't scrub it down or anything.
|
This and Joe Perez's thread are very helpful but my install is kicking my ass.
I removed the facia support thingy - had to cut some of the plastic fasteners but I don't expect that piece to ever fit back on. I have no way right now to make a support frame for the IC so I'm going to try to locate it approximately supported by a floor jack and then make the metal support. My car has AC so between that and the lower radiator hose plus the turbo drain hose its hard to figure where/ how to tun the hoses.... Tips, tricks and magic spells are greatly appreciated. |
Three year old thread.

There's no magic to it. I had a bunch of random bends and couplers. Cut to fit and assemble. I did have to remove the stock greddy oil drain pipe when I clocked the compressor down. Replaced it with a tunertoys drain kit and tapped the pan. Not sure if they're still around.

Thanks fellas :)
I think I'll also borrow a chop saw or a large pipe cutter to make things easier. It also looks that as much as I hate to do it the nose needs to come off - no ? |
BTW. This is what I have http://cgi.ebay.com/ebaymotors/CXRac...Q5fAccessories

Taking the front bumper on or off a miata sucks.

I have my IC all plumbed up. My next door neighbor if a freaking genius!!!! He visualized cuts angles and stuff really well so while he called where to cut I used a chop saw to cut the pipes. It went very fast !!!
I still need to find a way to secure the IC. We had the IC up on a floor jack while we set up the pipes. Where is a good place to buy two couplers and T clamps ? Need a 2&1/2 to 2 inch to connect the pipe to the turbo and a 2&1/2 to 2&1/4 coupler to slap a Cone to the turbo. |

Were you guys able to get the nose support and tray under the engine back on after the IC went on ? I jacked up the receiver dryer with my jack to make romm for the IC :giggle: |
Nose support, no, tray yes. I could fit both on if I was more aggressive with the trimming.

I still have a lot of work to do - still :cry: |

Thanks. I'm running out of $ so I might have to go with flebay couplers..

Just intercoolers on E-gay tried to screw me $6.00 for a 2 inch T clamp!!!
I bought my couplers from another E-gay vendors and found great prices on clamps on just couplers...oredered. |
