Boxster intercooler???....

[efahl]

PK,

Yes, Gary in BR's twin turbo install has an intercooler on the bottom of the motor where the aluminum stress plate originally resided. He has pictures here (or on sixspeed?) that show it pretty well.

The TTP installation puts the IC in the rear trunk, here's a pic:

Huh, Thats interesting, I thought about the trunk but couldn’t figure where any meaningful amount off fresh air would come from. Also, am I only seeing one pipe off that IC? ??

I’ll have to try to fin Gary’s pic.

Thanx, PK

mmmm, 390hp 3.2L twin tuuuuurbo...

*drooool*

Has anyone done a TTP turbo kit? Curious what the reliability is like.

Do you mean TPC?

No, I'm pretty sure he meant TTP. TPC is another company that makes a S/C for the boxster. Turbowerx offers a twin turbo setup that mounts the intercooler underneath the car as shown in the pic. Seems to me it would work alot better than in the trunk. I don't see how TTP can reliably crank out 390 hp out of the 3.2L unless they are lowering the compression and going to forged internals...and I don't think they are.

Ya, I have a TCP, and If he was referring to one, I could talk to it. I Googled “TTP turbo”, it’s apparently the name of some ghastly rap-something group. Google’s first page was dedicated to them, saw enough…

Don’t quite get how the air goes through the fins the Turbowerx set up.

Thanks, PK

15,500 Euro seems like a lot of money. Seems like you could spend you money more effectively either doing other things.

Here are a few pictures of my intercooler install.

Oops, forgot to point out that Gary's install is an air-air intercooler and the TTP is an air-water system, so no air goes through the trunk, just water lines.

The TTP 3.4 twin turbo does replace internals, but I don't think the 3.2 does...

It seems like water/air would is a nice solution, but I don’t get what TTP has going on in what would be the trunk. It appears to be the heat exchanger…but with only one tube??

Ideas?

Thanx PK

Hi Gary, Glad you showed up

-Is there a scoop of some sort that scoops air through that intercooler? If not, how does it have a cooling effect so close to the warm trans.

-I saw one of those pumps somewhere but not clear on what it does?

-Does the length of those tubes to the intercooler rob you of some charge flow? Or is that just “tuned in” or compensated for systemically.

Thanks,

PK

There are no scoops on the intercooler, I agree it makes sense to put scoops on it but Turbowerks did significant testing and did not see as need for the scoops.

The pump is the for the oil as Eric mentions. (thanks eric you explained it allot better than I could have.)

I am not 100% sure but I do know the system is producing 6lb of boost at the throttle body. So I would assume that if there is a pressure loss the turbos are producing enough to ensure the boost at the engine is correct.


Thanks,
