XR6 Turbo Question

[Mr. Oizo]

hey

Why does the XR6 Turbo have such a small intercooler?

is it because Ford doesnt want people to buy the cheaper XR6 Turbo, and have it with more power than the more expensive XR8?

or does it have to do more with the internals/drivetrain/gearbox not being able to handle the power?

thanks

no its due to the fact that the cooler does the job required to cool the 240kw of power without blocking the airflow for everything else, they done need to over engineer it

[redline2003]

in a way yes. those cars come out the factory running low boost(5psi??) and were slightly detuned so the xr8 would still b the 'godzilla' of the xr range, lower boost means no need for big cooler unless the customer wants it, if thats the case its up to the customer to replace with bigger cooler. most xr6 owners wouldnt want to ruin their warranty by boosting it or modding it and/or have little desire to turn it into a 13(or 12) second beast. would still prefer a r34 or s15 over it. on a side note, the internals and drivetrain are not weak, i havent heard good things about the gerabox though

They are fairly crazy on rolling starts, pulled nxt to a turbo ute presumably with atleast chiptorque etc floored it and he was just pulling slowly away.

I wasnt driving at the time tho so couldnt judge properly, Either way a 4L turbo cant be underestimated.. except for the 1600-1700 weight

Well since I'm Ford's chief designer on the XR6T Project, let me answer that........

The std cooler can't be that bad. A mate's 2002 XR6T is making 330rwkw with it still in place.

Nothing wrong with the standard cooler... If you think that's small, I take it you have never seen the R33 or 180sx side mount intercoolers?

probably due to the bigger capacity engine and lower boost there is less requirement for a bigger cooler than on a smaller capacity engine. I assume the turbo is bigger and therefore running the lower boost it doesn't build as much temperature back into the engine. Also the compression ratio is probably fairly detonation friendly for aussie conditions. Ford engines are generally pretty strong -- even the old ones. Most of the 80's falcons you can strap a turbo kit onto without massive dramas, whereas most of the commodores need more internal work.

...and probably most importantly to them: smaller = cheaper

As I understand it the XR6T is marginal on cooling as it is, so blocking the radiator with a big FMIC is a problem. This would explain why people are working on Water-Air intercoolers from them...

My friend is working on the FPV F6 Typhoon testing so I probably should ask him if that is right. I reckon they should make a Z-tune style bonnet from an XR8 bonnet
