you're basing the IC effectiveness on air temp at idle vs temps seen during the 8psi pull, right? no before/after air temp guages, etc?

 

I think he's comparing the rise in temp to his older, smaller intercooler.

 

Two questions.

1. Do you have pictures of your wastegate port? I know you did it yourself.
2. What kinda CLT temp difference are you seeing and when, cruise or boost?




Probably between cruise and boost.

 

on my last car i was seeing more like 170-180 cruise, now im seeing around 190 cruise and the fans are coming on more often. i did block about 75% of the radiator, where before it was more like 40%. plus i still have my license plate in the way

based on my old logs, the IC does a better job, but as i suspected at the cost of the cooling system, hence why I'm making an extractor hood.

pics of wastegate port:







enlarged it 15%, .88" to .92" IIRC, and added a small channel to help the flow.

 

well since i know the temp just before i boost it, it's kinda like that. 82° before boost, 86° at 6k and 8.2psi....never saw such a low rise before. FWIW, I used to see a 17-20°F delta with my old IC at 12-13psi....so i just need to man up and start tuning boost and taking more logs.

 

Pretty cool. Im curious to see the delta at that boost level though.

I dont remember, but you had to sac your AC to fit that IC right?

Also, did you do the port with a die grinder on the inside? What did you drill the hole with? Press?

 

You just need to build a motor and stop worrying about blowing things up...

At least your **** is in the car though.

 

Extractor will fix that temp rise

 

Get that scoop installed already. Im curiuos as to how much a difference you see.

Nope, still have a/c. see my build thread. or check my site under new_miata/intercooler

Dremel with die grinder bit. maybe 20 minutes worth of working, checking with a digital caliper as the work progressed.

 

built motors are bandaids for not knowing how to tune.

 

May I just say again, I love that site of yours. Could use better navigation but its still pretty awesome. I couldnt find the IC in there first time around.

You got the hole that round with a die grinder, impressive.

If my **** creeps, I may just have to follow in your footsteps.

 

you don't have a coolant reroute, do you, brain? i need to do something either in that department or an extractor hood soon. cruising on the highway last weekend, after about 30min at 4krpm, my temp guage needle was sitting probably 2/3 of the way up. i wasn't logging at the time, so i don't know exactly what it was, but i didn't like seeing the guage there, since i'm used to seeing it between 1/3 and 1/2 mark, as far as sweep is concerned...

 

once the fans kick on, im fine. and yes i have an extractor hood in the works. no coolant reroute bullshit im not overheating, just normals operating temps seem higher than my previous setup, which is fine.

 

I seriously have to figure out this CLT sensor stuff on my car, im still letting it peg at 215. Thats def not gonna be good with a turbo on the engine.

 

Were you fixing boost creep with the port job? did it work? notice any difference?

 

Damn, my water temps peg 220 with turbo and thats only if im sitting still for too long. The hood deff helps but I think my fans are the weak point.

No No, you dont get it papi.

My MS reads the temp off the sensor wrong because the resistance values or bias resistance value is incorrect. There seems to be some confusion with the 96/97 cars in terms of that.

 

yeah, wastegate was hitting 10psi at 3600rpm before and rising to something like 14psi at redline. I haven't made any WOT pulls, but from what i can tell the creep is gone....EBC map will be the best test. I was dropping the 0% DC at redline

 

LOL so true... (Says the guy who is running stock management while building his MSII).

levnubhin those temps seem high...I never see above 212 on my Scangauge even when beating on it. This is with stock cooling as well, should drop even more with the oil cooler installed.
