I had a 98 prelude a couple years back, and i bypassed the coolant line to the throttle body and was impressed with the results for being such an easy and FREE mod. basically, it keeps the intake air cooler since the throttle body doesn't get heated up by the coolant. it probably feels like 3-5 hp by my butt-dyno.

you can't do it when it's cool out (72 or so and below) b/c the engine tries to compensate and it just would shake and then go into limp mode with the "check engine" light on. but here in FL, esp now, i figure it would work great....

but is it even possible on the type r?? still getting familiar with her myself.

 

It is possible but doesn''t yield enough power to warrant the work or troubles.

 

like Trey said, it's possible but I wouldn't waste my time, plus the likely hood of a hunting idle makes it not worth it. (the only car I've done this to suffered from the hunting idle problem, :shrug

you can sense 3-5hp with your butt? damn, you have a sensitive butt.

 

My ITR's TB heater is currently disconnected. I do not know what specific gains we got out of it, because the car was tested after everything was done.

As of now, we do not intend to reconnect it in the fall.

We'll see what happens.
