Upgrade To The GP Intercooler

[-=gRay rAvEn=-]

Picking up all the parts needed to swap out my current set up this week (GP parts are being shipped direct from Germany).

Was wondering if anyone here is running this set up (Obviously, besides GP owners) and had any opinion on it.

BTW: If you have intercooler post air temp figures from your Scan Guage II...that would be great too.

I'd be interested to hear of your results to be honest.

I have read a few post....said it was awesome on the dino...very light, and recovered very quickly, and miniumal back pressure!! Mynes said it was the best he has seen on a post on MA. I'm interested to see how much it helps....I bet it will negate the effect of the extra heat from the pulley....and make the awesome!!

[Dr Obnxs]

and I'm running one. When I did some pressure drop tests, the GP didn't really do that much better. In fact the one I had did worse than the stock unit!

Also, the extra two rows require the air flow to bend a lot, the mass of the air and it's inertia would tend to make the air flow through the paths in front of the port, so the benefit would be less than the increased capacity would first suggest. One way to deal with this is baffles in the end-tank, but the GP doesn't use them.

There is no complete data set comparing the GP to the stock.

I ran the GP IC on my car for several months and while only going on scanguage data the improvements over the stock unit were only slight (if any).
Ended up selling it and put the money towards a head...

Here is some good info from K-huveo

If you want to reduce IAT's get a meth kit

[ZippyNH]

Oh well....I always been a pessimist....but I'll try to stay optimistic!! If anything else it will be some $$ bling for under the hood!! I'm still optimistic that the combo of a 17% reduction making more heat and volume will benefit more than a 15%...Maybe porting and polishing the supercharger outlet duct...then a ported head would be next!! I love spending other people money!! Heck....I keep on reading mods, and spending my own!!

Got my fingers crossed.

I have a DFIC Scoop I can use which to a degree concentrates and directs the air flow somewhat, I was hoping it would aid in pushing the air to the back rows more efficiently ? Or maybe the one from Volatge Products....any chance that would help ?

We've done the Meth kit, and they do work well. But we have something else at the shop along the same lines which will hopefully go in this week. Will post some pics when it's all installed and we gather some data. Kudos to K-huveo, some nice work there, thanks for the link D-Man.

Hopefully if all goes well, and Jan comes to CT in the Spring, we will have additional dyno runs done to check on how these mods pan out.

[bahawton]

I have one with the M7 scoop for a little more air flow.

I wish I could tell you I noticed a difference, but I didn't.

I'm running this set up because I plan on installing a slightly smaller (15%) pulley than my current JCW pulley.

My hope is less ignition timing retardation when hammering it on a hot summer's day ; )

[Helix13mini]

I ran one on the Helix Shop MINI, after testing all sorts of intercoolers. Our IAT's were still sky high at 7200 rpm with a 17% pulley, but the recovery rates were so much better than the alternatives. My findings were that big, heavy aftermarket intercoolers would heat soak in real-world conditions. We made one intercooler (which I still have on the shelf) that was good for one hail-Mary dyno run, producing good power with less-than-stock pressure drop. After that run, we would have to soak the cooler with water and put a carpet drying fan on it for 10 minutes to get it back to reasonable temperatures. This is the case with all of the aftermarket cooler that I've looked at: they're a good heat sink for a single run, but in real world conditions, they are doing a nice job pre-heating the intake charge.

I can't speak for the water to air offerings, since I haven't tested them. The DOS cooler with the Laminova core looks interesting to me. If I had burnin' money, I'd buy one just to dyno.

This kind of brings me to something that I've been chewing on lately: do people think that there is a market for a thin core like the GP? One that is not a huge heat sink, has a quick recovery rate, has excellent efficiency, and doesn't cost a mint? We could improve on a couple of things (like Dr. O's comment on the extra rows being out of the natural flow path). I've bounced a couple of napkin sketches to our cooling guy (who vetoed my first one ) but he likes the direction. I'm interested to see if there's enough interest to continue the pursuit.

[daflake]

I would be interested....

What with all of the posts, tests, first hand accounts this is a waste of money that could be better spent in other mods.

I like it

I would add material to the core's intake area which would direct the air flow more evenly across the cooling area yet not disrupt the natural flow to prevent pressure loss. Then fabricate the surface fins like a set of stairs progressing with the tallest step at the back of the intercooler to capture the intake air more evenly as well. At that point a IC cover with vents is moot.

But, but, but.....bigshot ? I have done most other mods already. At least those that will not take away from my MINI as being a reliable daily driver....

You really need to know GR to understand GR. He really should start his own BLOG on parts that he has tried over the time.

[newbs49]

I think there will always be interest in a intercooler that really works, especially on cars that see track time. Also a hood scoop that was designed in conjuction with the intercooler to maximize air flow.

[Bigshot]

So a fool and his money are............

[-=gRay rAvEn=-]

LOL, and it's a good thing there is a market for these used non wearable parts too.

Keeps me from running out of cabinet space........

Not a fool BS.....just having fun and I document results.

And no pun on the BS there either big guy.

[daflake]

He does what many are afraid to do, he tries it and then posts the results. Nothing wrong with that if you ask me.

[Bigshot]

Just not sure why GR would go down this path when so many have done it before and posted their results.

But when he asks for opinions on it, it looks like he hasn't really done any research on the product.

Have fun playing with the new IC GR.

[-=gRay rAvEn=-]

Actually, MC2 has more data on it there BS......at least that which was written. Was not able to locate much on a search here. Some data was even somewhat conflicting. And not all modders even bother to post their stuff so in an attempt to be thorough, I felt ASKING was the best recourse and may even glean unreported undocumented data.

But if you must know with respect to the IC......I am going back to semi-stock to enable a device to be attached to the IC for lower IC temps. Hopefully with drops up to 50/60 degrees.

And my methods may seem bit unorthodox to you, but you didnt write the book on it. And since retiring early at the ripe age of 47, after working my butt off since I was 17, I just figured it was finally time to have some FUN in my life...

Looks can be deceiving.....

[Bigshot]

Like I said have fun with it. And keep us informed of the "new" product you are working on. Love to see new things brought to light.

[-=gRay rAvEn=-]

[newbs49]

Keep us informed.
Congrats on early retirement.
