I *think* SG also offers a 3.5 inch intercooler unrelated to the RS Tuning product (and MUCH less expensive). Its not on their obsolete website.

here is a pic of the 3.5" Blownsix Design intercoolers which i have been waiting for, i will have these installed next week!! The tanks are polished on the inside too for air-flow. Cheers.

 

How much? and are they compatible with the evo boost kit?

 

Honestly I dont like the end tanks....so small and narrow at the ends.... those are as narrow as the stock plastic ones.... mine are not the prettiest but definatelly potent.
not to say mine are better.. but honestly look and compare.... and these are proven and approved by Todd Knighton.
they will be pushing 2 garrett gt35r on on TT.
the last one is my custom evo IC tahst doing low 10s at the track.

 

I agree with Markski. Those end tanks appear to suffer from the same design shortcomings as the stock end tanks. In particular, significant portions of the intercooler cores are obstructed by the end tank. IMHO, the folliwing is a much better design:

Looks like urs came out nice craig

 

the ones in the pic are the prototype and further impovement may be made; the price is usd1985/pr. Cheers.

 

if your talking facyory gt2 intercoolers the offer only 10% more surface area. i have them only because i am in a hot weather area..no performance dif for me wait for the larger ones to come out a real difference imo

 

I agree steve... I upgraded as well at one time to the GT2s... if u want to be in the real world u need good cooling... and stock ICs are not good for 6000 HP... we make ICs and intake plenums at the evo shop and when my tuner saw the stock Ics... he couldnt stop laughing.... and he builds 9 second 2 liter cars regularly... so I assume he knows his sh@t. tube and fin design is inferior to bar and plate... and the stock endtanks are very restrictive.

 

The Cargraphics/RS-Tuning intercoolers are the same SECAN intercoolers used on the Jurgen Alzen 996 Turbo racecar. So obviously, they work well, and are proven to work under endurance race conditions at 700bhp. And I'm talking a REAL 700hp, not Dynojet 700 horse.

Todd K/Protomotive ICs work extremely well. They offer something like 98% efficiency... can YOUR intercooler do that?

 

I would just like to add briefly (intercooler discussions often turn sour!)..

One has to think that if there are some intercoolers that are being used by one of the most reputable builders in the world for their >640HP cars, having the most extensive racing palmares in the world, one must consider at least that they know something better than their lousy customer service.

I don't understand honestly why all this focus on the dimensions and design of end tanks and core and how they look etc? It is not about the dimensions (only) it is obviously about the quality of the core and how it is built , which materials, what size of fins, plates, tubes, bars, how they flow internally, what are the expansion rates of the components, what is the pressure drop resulting from its design, front to back or side to side etc...

I can tell you that Secan intercooler core design takes an immense amount of time and extremely expensive equipment, used by some of the best thermodynamics engineers in the world, who are nothing less than aerospace engineers (the same ones who build the european and US space shuttles, do components for Boeing, Airbus, Jet fighters, helicopters etc..), and as a matter of fact, this French aerospace company is a subsidiary of the Honeywell Aerospace group.

RS Tuning has a very special relationship with Secan and can get them to build these cores for them, the same that Posrche Motorsport used on all its GT racing cars. Try to get your hands on a Secan from the french factory, regardless of how much you are willing to pay, you can't.

For a quartermile run you might not need them, but for anything more than 1 lap on a track, or sustained high boost run (>1.3 Bar or so on the watercooled cars) expect to see your HP drop by 20-30% easily. If you run 1.5 Bar, your drops can be 40% easily on the race track.

There is a reason Spearco, Bell, Higgins and many others cost 1/10th or less of Secan, it is not the Euro, nor that they are thiefs, and I would assume that the best racing companies in the world (even Caddillac used them on their race cars!) know why they are paying so much for them.

I wanted to be brief, I apologize for not doing so. I have an aircooled engine, and spend A LOT of time analyzing the impact of heat on its performance, I have track datalogs that show it, intercooler efficiency is my biggest ennemy, you guys can get away with a bit less than me, but not at anything above 1.2-1.3 Bar...No can be!

The Alzen car was readjusted to run 0.9 Bar in endurance FWIW. Nurburgring 24 hours is in a few days, that is the real test.

 

If Secan is part of Honeywell, I wonder if my friends working for Honeywell can get me the employee discount?

 

Having an intercooler with 98% efficiency would be great, however i don't think those numbers are scientifically possible.

 

A racing team here in Belgium used Secan in the past but now they use Blizzard intercoolers on the 996 turbo (running 700hp at 0.9bar of boost) maximum temperature difference between intake and ambient is 11°C during the race!!
