right im kinda farting against thunder then really without suitable mapping hehe if top engineers say after years of experience they need setup correctly with ecu then i think a 20 year old like me has no hope haha! ill just stick to bike carbs hehe they are tunable without expensive computers lol

yes true but this doesn't mean at higher revs all cylinders get the same amount of air surely it goes against everything i know if you have to run to the shop but i have to run next door all in a millisecond before the door(valve) shuts im going to get there first

all honda b series intakes are like this most d series remember manufacturers arn't thinking performance when they design little cars with small engines. a bigger plenum surely would almost eliminate this problem anyway back to the ITB idea you think my first drawing could work on standard ecu...

ok thats good to know its a learning curve! its not fuel thats the issue its air think about it the runner furthest from the throttle body at say 7k rpm is having to scavenge from the plenum what the other cylinders havn't used as they are closer to the incoming air supply

even if i have to use small ITB's so long as they are equal to the throttle plate area of an upgraded or standard throttle body surely the cylinders will only fill the same amount of air as normal BUT have better distribution of that air ie usually the cylinder furthest from the throttle body at...

Heres my idea feel free to shoot it down haha like i say i don't have much knowledge on ITB's ooooft low rider that would require alot of money :P

you think? thats good

True frank yes! but most cars that come standard with ITB's have a plenum before the bodies with filter and MAF connected up its more also the fact that each cylinder gets equal volumes of air as apposed to how quickly it can get it in (just my educated guess as a mechanic i am in no way...

Any more advance on this situation?! I too would love the challenge of getting throttle bodies running on standard engine management ;) with use or wide band ect complete diy

well cheap as possible really how much for the complete head vs the head without the cams? cheers

Wanting to start building an all motor but need a head to start with wondering if any of you have spare head sitting about unused in working condition preferebly with all valve train and cams thanks alot!

If you have changed all this it is almost certainly a wiring, earth fault if not faulty bulb

Surely if you have a plenum before the throttle bodies with the air flow meter mounted somehow it will let ecu know airflow in relation to throttle position and the ecu should fuel in relation thinking of doing this also with no map sensor to deal with I bet you could get this running and...

That manifold must have taken you ages to make it looks very good though!! How did you cut out the initial flange shape?! Dremmel?! Also what thickness off steel was it?! 10mm?! Cheers mate

Cheers mate a man of my own heart haha I too love tinkering and kinda like it when something isn't quite 100% so I can figure it out and redo it agh a vacuum dizzy I was going to ask about this now I know haha I shall defo be looking into this as vacuum advance plays a huge roll in acceleration...

That's I'd simply awsome!! Minted job man ill read over this again after work! But thanks alot for the pics!!!

sweet cheers!

ooo sounds fancy frank enlighten me haha id love to be able to at least know a little about whats going on in there when im foot to the board lol!

that would work i assume but like skinner i live on an island also so no rolling road and the ferry cost are just insane so its down to the old school approach adjust ignition advance via dizzy test and repeat i think ive bugged skinner about his setup so hopefully he can enlighten me =] and...
