I hope you didn't mean 6k continuous for few minutes? Coz that would be ridiculous...

Depends on what he means by a "few".

Looking at some data from my lap timer, I'm above 4K 95% of the time, above 5K probably 75% of the time, and above 6K maybe 30% of the time on the track.

6K might be overkill but he ran continuously at 5k or 5.5K that would be a good estimation of track load. Ideally he'd cycle up/down between 5K and 7K.

Why bypass the TB coolant lines?

Surely they wouldn't over-engineer the TB to include a coolant loop if it wasn't needed.

The throttle body coolant lines are there more for heating the TB on super cold mornings than for cooling anything.

Unless you live where it gets super duper cold, removing those lines from the TB won't hurt anything.

Is this basically the same thing shown in this thread? http://www.ft86club.com/forums/showthread.php?t=50427

Just a different way of installing the coolant hoses?

Good info & observations. I'll certainly be look at this cooling route my self, certainly more elegant than the Laminova air/water intercoolers I've used in the past.

Ahh yes! I forget not everywhere is as mild as Australia! :)

interesting when can we get some WOT/track analysis? :)

Would like to know too? Seem identical to the other one but double the price?
