Greddy I/C question

[paul s]

I running the Greddy 24 (big) intercooler and was just wondering if you guys think that its too small for my set up. I was running 31psi on a 3065 turbo and had the boost controller maxed out and it would not make more power. Max timing at 14deg and A/F at 11.5 on 100oct fuel. It made 405 awhp on mustang dyno. Any suggestions would be great.

You can always go with a larger Sparco IC if you so choose. Have you done anything in terms of ducting?

 

[paul s]

My I/C is flush with the bumper, the air has nowhere to go but through the i/c and then the rad. All the temps were normal..

If you don't have ducting between the intercooler and the radiator, the air can escape.

If you run too much boost on your intercooler and it heat soaks the intercooler you'll see knock especially in higher gears. You could always sell your Greddy FMIC and pick up a XS/SSAC for under $350 shipped.

True and yes. Exactly what I went through. After just a few runs, the IC heat soaked, and I would get knock. Sold the big greddy 24r, got the SSAC kit for the 2g (made a profit selling the brand name junkie fmic), and the ic heat soaking has never been an issue with my 50trim setup.

Paul isn't heat-soaking his IC, it simply doesn't flow enough for his HP goals. Greddy themselves even said so.

I will put the greddy on my wifes talon and get a 3.5/10/25 from ETS..On the dyno we were spraying the I/C with water. The ducting will help to keep the coolant temps. On the dyno everything was pretty cool oil/water was at 187deg F..

Sparco makes seats. Spearco makes intercoolers.

The only thing I can think of to add is also the pipe routing. Greddy's piping is a lot longer than most others. I've got a few friends with Slowboy race FMIC's with Buschur style piping and they are having no problems what so ever. Hell, Dan's even flirting with 10's.

Paul, I would think at those kind of boost levels, the Greddy setup has to be a restriction, not to mention their great long route pipe. The tube & fin core is less then ideal & it uses the smaller 2.25" pipes. I think you have the right idea, step up to a nice bar & plate ETS setup with the short route, larger diameter pipes.

It would defently be interesting to do some back to back testing to get some before & after logs, to see if you noitce gains. I know its not the same but when I went from the large HRC bar & plate SMIC to my VP FMIC setup, I picked up over 2 lb/min on average with no other changes. Add the additional cooling of the FMIC setup & it turned out to be a nice bump in power, actually more so then I expected without changing anything else on my setup.

Yeah, that's what I meant. Stupid me.

 

[paul s]

I will change the I/C in the near future, I do hace 2.5 inch piping now.

Well if you read the specs on the Greddy IC, the piping that comes with it if you buy it as a kit is designed to fit a stock T25 turbo. Granted it can flow more than what you would do with a T25, Pushing 400+ hp I can imagine you would run into some issues.

I dont know what 404hp on a mustang dyno campares to a dynojet but i just got dynoing a 2.0 3065 car at AMS and it only made 505hp at 28psi. I have to say i was not impressed by the power but AMS would not go any higher with the boost even though we were on 100 octane.

 

[paul s]

I had the boost controller at 100% so the boost would not go any higher, on one run the boost got up to 33psi but the car would not make more power. here is vid of one pull.

What are you doing? Trying to make us jealous?

Have you checked for boost leaks anywhere?

 

[Boosted98gsx]

at 35 psi on a 3065, you only made 406whp?

21 psi on an evo3 16g got me 386 tq and 362 hp (also on a mustang, mine was however, very uncalibrated). There's something seriously wrong with your setup.

 

[paul s]

I don't know whelse could be wrong with it. It runs good idles ok and I have pressure tested to 35psi..I get 60-90mph around 2.75 sec in 3rd.

Time for a new FMIC with some better engineered piping.

 

[paul s]

I will be getting ETS race core with some meth for the spring..

You're in a 2g, I would recommend the DV/DT fab core, I run it and the thing is ####ing awesome. Going to be difficult to get Albert to fab one up for you though. I think he's only making the actual intercooler and no piping at this point.

http://dvdtfab.com/2g_intercooler_kit.htm

I stand corrected. He will make piping, but I don't know what it will cost. Core available for $800 though.

 

[1bad92awd]

Let us know if the new IC helps your situation. I would be interested in seeing what the verdict is

 

[paul s]

I will do my homework before buying it, I will post the results once everything is set up. I have made logs now at few boost levels so I can compare results.
