Intercooler advise plz....

[mike 850]

is this comparing the old do88 to the new one? so the original is only marginally better than factory so definitely worth checking on the 2nd hand market for the revised version? quite a difference

yes it is mike.
as I mentioned the whole intention of the original was to stop the problem of them cracking under high boost.
now they have more technology and experience the result speaks for itself.
I think the original intercooler was one of the first things they ever made.

I doubt you'll find a second hand one, it hasn't been out a year yet.
the revised version has the do88 logo on the end tank. the original was plain.

ref universal intercoolers, all of the discussions I have had with do88 about how they make significant improvements indicate the design of the end tank is critical for good flow over the whole width of the intercooler.
when they redeveloped the 850 intercooler they redesigned the end tanks again using cad, and got massive gains over their previous first version which was made in alloy specifically to stop the problem of the original ones splitting with high boost.

That graph is interesting, the IAT actually goes down during gear change by looks of it?

it probably goes down because the air flow amount would drop during gearchange, making the intercooler more effective.

they hire a runway for the day to do their testing.
their demo car is a 850 t5 with 400 bhp garret turbo and full data logging , that has the intercooler pipes through the headlights and a front mounted frame. this way they can fit the original intercooler, run, then swap easily for the uprated one and take readings in exactly the same conditions.
they cheat though because it runs on E85, I have told them this!

we recently discussed options upgrading their brakes, because apparently there is a concrete wall at the end of the runway and they still had standard oe brakes fitted......... brown trousers

So not really true results for a road going average T5. They should have bolted their ic to a standard T5 then tested to see what the results were over a stock car.
