    basically yer. even flow and the ability to take in shit loads more air. whilst the itbs are small individually. collectively they are a MUCH bigger area then a single TB bringing in alot more. and asways. more air allows for more fuel, which makes bigger "bang" which makes more power

    lol, not even the IMSA cars had bonnet vents so thats just a purist thing Rev

    this will be the 1st 4th gen with ITB's, which is awesome coz i love being different lol
    Not quite, 4th gen street maybe? - ALL the race 3S-GE's had ITB's, later motors had reversed heads as well with the ITB's over the radiator eg -

    This German hillclimb car is fitted with an ex-BTCC reverse head motor, ITB's & sequential gearbox

    TOM's F3 motors also sported ITB's but were restricted to stock heads/blocks

    Here's a 3rd gen idea, I think the runners need to be kept short or keep the injectors in the head

    Gen1's have long been a favourite with Midget racers, here you can see why nobody wants to try fit them in a roadcar

    you can get a plate on ebay for the mounting of itbs. also this will be the first street car and street motor with itbs in a 4th gen. to my knowledge anyways. most itb 3sge's use a special reversed head.

    oh rev...i do hope you have a stand alone system on order. you won't be able to use your afm unless you put a volumizer on top of the itbs

    Unfortunately i havent had alot of time to play with the throttle bodies yet. seems to be every time i start to get things happening to my car i have to fix someone else. i.e remove and fit a new radiator for a mate. fix my girlfriends sisters car after a crash etc etc anywho

    this is where im at with the throttles. I have seperated them and removed the secondary butterflys (not required nor wanted) now doing this leaves 2 holes in each TB. no big deal but just a lil morw work. have filled the holes with selleys steel reiforced kneed it (JB weld equivelant).
    Have done the same for the standard TB injector ports. on the quads the factory injector ports are directly behind the butterfly. this supposedly is for better atamozation of the fuel but to use that location would have been a PIA. custom brackets for a fuel rail and would have to bore out the injector holes. instead im going to use factory fuel rail setup and have filled these holes.

    heres some pics of my dodgy filing jobs. mind you no matter how smoothly i filled the holes i would have still had to grind away excess.

    Secondary butterfly holes

    [​IMG]

    and how the throttles are sitting ATM

    [​IMG]

    So next step is to dissasemble the butterflys and grind back and smooth the patch jobs.
    Then after that i will be adressing the trottle cable mounting. at this stage i will be welding a nut to the stock qaud throttle actuator and fitting a standard 3sge throttle actuator to it. in theory this will allow me to retain the standard throttle cable and standard pedal travel. only PIA will be making a bracket to hold tention on the factory cable, if all goes to plan anywayz lol.

    more update when i have something to update you with :)
