Hi!
Gona get straight to it, I have 4 bravo 80 cable throttle bodies, I can get a diesel alternator for the vaccum servo, I can make the plate for them to sit on (I'm planning to use the metal part of the intake and make a scoop in the bonnet :D) link them all up etc, can i run them on my car without too much hassle? In terms of will I have to go down the route of a new ecm? Remapping is not a problem. I don't want to run the car without the sensors in the manifold if I can help it...
Any help is appreciated!!(y)
 
if this crazy plan works please make it a shaker hood :) shaker intakes are cheap

what engine?
1.2 16v, cable throttle.

I hope it all works, those 3 tb's wern't cheap!! :cry: I chose not to go down the route of jenveys or bike tbs due to the absence of where to put the stepper motor... This way i can keep the stock ecu!

That might be a better idea then what i originally thought up.... I was going to butcher up my bonnet (its fairly crappy) and an old BMW bonnet (same cond) weld the raised centre of the bm bonnet to the bravo bonnet and fit a ram scoop.... Ill keep the shaker hood idea in mind tho! (y)

For the moment, the car has to be sorted for its nct, then when it has it ill start on the itb's :D

That idea of mine isnt going to work. 4 stepper motors is messy and the cable is under pressure :mad:

I'm going to save up instead and buy a microsquirt ecu and go from there. But for the moment that other idea is out the window.... Anyone need throttle bodies or stepper motors? I have 2 of each to sell on!

Someday i'll put another post up on this thread!! ;)
 
it wouldn't have worked anyway. you're trying to fit 4 tb's, each designed to fed air to 4 cylinders. they would be too big and you'd just lose power and torque. if u look at a set of proper ITB's, ie weber, jenvey, oem fitments, etc you'll notice they're much smaller in diameter. the diameter, and length, is crucial and needs to be calculated to specific engine perameters. fitting bike tb's isn't the best solution for this reason, as they're not the correct diameter for the new application, how length can easily be adjusted by changing the inlet trumpets.

on a road car you would be far better off [slightly] increasing the diameter of your existing single tb to allow it to flow a little more air and team it up with revised induction, exhaust and a suitable remap.
 
It did, just not very well :mad:

I'm going to fully research a megasquirt or microsquirt setup then go from there (y)

my point exactly. either it works well or it doesn't.

there's alot of reading up to do for the megasquirt, have fun. i'm planning on fitting one to the hgt
