Your HM vacume log is a work of art.

what do you do with the coolant lines, IACV and all that, just loop them??

SkunT

the IACV just hang that ****** somewhere, zip tie it off. NO COOLANT GOES THROUGH IT! -NOTHING THAT WILL SPILL OUT OR ANYTHING!

To get peak hp with the ITB's you have to tune it, yes it will run off a stock ecu but not nearly at its fullest potential. Steve's right I'd go with a set of ITR cams and the itb's would probably work out pretty good for a budget build.

So EGYSOL, have we chaunged our mind and no longer going turbo after that long *** thread about what t3 turbo you want to get? A HM-ITB setup is going to require a custom intake head flange (or modified stock one) a set of ITB's, and something to tune it with.

Good luck,

Jeff

I love it when people make a thread and never come back to it.

LOL...thats a pet peeve of mine too, especially when you go to lengths trying to explain something.

are there any dynos or good sites yall know of showing the gains or advantages to ITBs on Hondas?

So I gotta question...

How is it that 4 TBs off of an 1100cc motorcycle, can flow enough to provide sufficient air to a 1600cc car? Just doesn't seem like it will work to maximum efficiency.

I guess you'd have to compare the square area of the stock TB, to the combined square area of the four individual TBs. Does that sound right?

the motorcycle's revving twice as fast also. so you figure the air intake for an 1100cc motorcycle at 12000 rpm vs the air intake of a 1600cc car at 7000 rpm. that and 4 40-45mm throttle bodies are larger then one 60 mm one. it's like useing 16 smaller valves in a head versus 8 large ones. most motorcycle itb's have secondary butterflys also, which compensate for the larger TB area at low rpms

the surface area of a 62mm throttle body is appx 97mm2 whereas the surface area of 4 40mm throttle bodies add up to 251mm2 (equating to the surface area of a 160mm throttlebody)
