My sexy new project!
 

Well, as most of you know, the turbo project got killed, but now a NEW project lives!! HAHAHAHAHAHAHAHAHAA

So, whata think? I'm still getting the spacing right, so that's what the plastic spacers are for. once i get it set, i'm pulling those and haveing aluminium ones made, and a steel bar welded across the bottom. My biggest problem now, is i need an intake manifold with straight runner, or i need to find someone to make me a blank intake flange (like the exhuast flanges that they where selling in the classifies for making exhaust manifolds.

Re:My sexy new project!
 

How much was that setup? Is that off a newer bike?

Re:My sexy new project!
 

what?? a newer bike?? what are you talking about?

Re:My sexy new project!
 

i'm in about $200 right now, for the FPR, fuel rail, and the TB's. They are off a '01 Suzuki GSXR 1000cc bike. It's going to end up costing me more in the long run than a turbo, but i can't run in my class (SCCA) if i change the induction, but the rule book says intake/tb's/and injectors are "FREE" (i can atest that none of this has been free so far, but i'll keep you up to date)

;D

Re:My sexy new project!
 

Sweet. If you can get a Cadd drawing of the flange you need I can get it cut out. It will probably be around $20 or so. I can get the throttle body flanges also. Looks like a pretty neat setup and should do well if you decide to turbocharge it also.

*rumages through his list of software titles*

A-HA!! i have autocad 2001, and my father in law uses it all the time, i'll load him up at home and see if he can do one up.

Re:My sexy new project!
 

thought about throttle control at all?? Imagine turbo a quad TB setup.. insane.

Re:My sexy new project!
 

What ECU would you run with that? My guess is that a stock system would be a tad difficult to tune..

Re:My sexy new project!
 

yeah, right now i'm work on getting the TPS sensor hook up. all the vacuum dependant sensors/parts are going to be run off a vacuum box (just need to figure out one to use). right behind all the TB's theres 2 lines for vacuum, so i'm going to tie all them together, then into one box. i'm going to have to fabricate a throttle cable since the one is 90 degrees to what stock tb's are (this wo't be to had at all, jsut a round pull that spins very free). i've found most of the spacing parts i need at mcmaster (yeah them!). a little bending of the TB plate arms is going to be need since they are about 1/2 inch farther apart then what they used to be. i'm anxious to see what kind power i am going to be able to pull out these. should be fun to run these in the NA bracket at the strip too.

;D

Re:My sexy new project!
 

I still dont see how you are going to tune the thing with those. Are you getting something like hondata/zdyne/EMS?

Re:My sexy new project!
 

tuning is stage 2, i'm only in stage 1 (manufacuring). i'm hoping that i can get a decent tune with a stock ecu and a ghettodyne chip. i'll have to get the injectors balanced so they all match flow rates. i'm going to tune it with the stock manifold (so the O2 sensor is reading from all cylinders, since my headers have the O2 sensor on just 1 runner). since i'm sure the engine is going to be done before these are, i'm goign to run a Y8 intake on that for a while, then switch to the ITB's once they are read.

Re:My sexy new project!
 

Mind taking a picture of the flange side? so we can see how they look? what size are the throttle bodys? (per each)

I really like the idea, but it might be a ---- to get everything working... ;)

Re:My sexy new project!
 

wont a MAP system work Jeff?

Re:My sexy new project!
 

the second pic down is the "head" side of the set-up. the throttle plates about about 2/3 the way back in the runners. i was thinking about that after i posted them here at work, i KNEW someone would ask me the diameter of the runners. i'm not positive (but i'm abot 85%), they are just under 2 inches each. i was looking at some 2 inch K&N cones the other day, so i'm pretty sure that's the size. so you can figure i'll be running the equvilant of abot a 7.5 inch throttle plate.

;D

as for being a "----" to tune, well, if it was easy, then there won't be any fun in doing it.

Re:My sexy new project!
 

nonono. I wanna see pics of what the runners look like (off the throttle bodys), where they are at, what is the shape etc...

Just get a factory intake manifold gasket, take it to a CNC machine shop and have them make you a flange, or use a facotry manifold, chop the fucker and weld some runners on that. (kinda like my ZC intake manifold)

what size are the TB's? in mm's?

Jeff

Re:My sexy new project!
 

i'll measure them better when i get home. i haven't made the runners to the flange yet, that's what i'm looking up today, see if i can find someone to make me one. good idea on the gasket though. i need one with-out the "injector bump" in it though, since the injectors sit right behind the TB plates. i'm guessing about 2 inch runner (from the flange to where the will meet the tb's). that'll give me a little over 4 inches of total runner (about and inch more than you HAVE to have). the runne will come straight out of the head (parallel to the ground) and be cut at a slight angle (up) where a plate will be welded to it. that's where the TB's will bolt to. i'll draw it all up tonight and scan it in, to get some feed back.

Re:My sexy new project!
 

As long as you only use one tps and its calabrated the same as stock why would you have tuning problems?

Re:My sexy new project!
 

it'll be one TPS, but you now have 4 throttle bodies (which aren't all linked with one solid bar. also, the subtle differences in your cylinders will cause different amount of air flow/fuel mixture. i think the hardest part is going to be here to start with the fuel map. at least witha turbo, you have maps you can start with that are close, then tuen from there, i'll have to jus guess a few times, then adjust it from there.

Re:My sexy new project!
 

could you use a AFC to trick the ecu? Like.. the extra 3 tbs will get more air into the cyl. So get the AFC to dump in extra fuel ?

Re:My sexy new project!
 

I really think the stock computer will do ok. I mean your talking about the need to tune individual cylnders.. Thats going to take a pretty complex ecu with egt probes in each exhaust runner.

Re:My sexy new project!
 

Why don't you just put some small k&n's on the TB's? why do you need an intake manifold(with a vaccum box)?. I've heard individual TB's totally change the sound of the engine.

Re:My sexy new project!
 

i will have K&N's on each on the TB's, but you still need a vacuum box to run the FPR, MAP, and other vac dependant items. i'm jsut going to mount a small box on the firewall, and use that. but i will have 4 K&N filters on the intakes. i have been told that ITB's (individual throttle bodies) do make a big change in engine sound, since you not have to pull through a vaccum as much, that's also where the extra power comes in.

Re:My sexy new project!
 

Most of the ITB setups use TPS as a signal for load rather than MAP. The MAP signal can be too eratic to provide good info to the ECU.

You really will need to be able to tune the fuel as well, once the initial idle is balanced on each one. The air provided by a properly sized system will far exceed what a stock ECU will be expecting.

Also, this will need to run at very high RPM to realize the potential of the ITB, with cams and proper cam timing as well. Great project, what size are those?

Here is Jim Hills setup...... whats ETA on that now? 2006 ;)

Re:My sexy new project!
 

damn, i need that flange and runner setup. exactly liek what i'm looking for, except for the tb side to have a slight up angle on it.

Re:My sexy new project!
 

that flange might be hard to get cnc'd , you need to have the injector bosses cut into it. mani's i have seen are cast from a mold and then the injector bosses machined out. let me know how you end up making it, i am trying to get some of those flanges made. i will make a drawing later i'm too tired now.

Re:My sexy new project!
 

I'm not too knowledgable about bikes. Do all bikes have individual throttle bodies?

Re:My sexy new project!
 

yes pretty all that ive ever seen have seprate tb's... :) and ive seen alot of bikes..

Re:My sexy new project!
 

;D Neat huh? I hear they do all kinds of crazy stuff to the 86 Corollas with bike parts.

Re:My sexy new project!
 

I think TODA sells ITB's for AE86 Crapola. I never understood how bike engines work. Are they like lawnmower engines, or car engines? I want a bike now. I have a lawnmower and a pedal bike. Help me out here.

Re:My sexy new project!
 

since the wife and i just bought a new mower, my cousin and i are building a go-cart with a 4.5hp briggs motor... and yes, are thinking SCed or Turboed.

Re:My sexy new project!
 

toda sells em for b engines.. the funiest thing is that their higest respected race program running the fastest NA civc doesnt utilize the itb or what they call sport injection..

Re:My sexy new project!
 

Thats what mine is, 4.5 hp briggs and straton. Hardcore.

Re:My sexy new project!
 

IF you are serious, and you dont know what a bike engine is then here ya go.

Usually a bike engine is a small car engine. (Honda, Civic, 1.6l. Honda Bike CBR600F4i = 600cc, .6l)

difference is that the bike revs to 15,000RPM.

Re:My sexy new project!
 

SO if i get the throttle bodys off of the jeksr 1000, toda has a programable ecu for a bout 600, are u sure they came of a bike, i heard that they are only good for take off and not mush tourqe, but you can turbo those also

Re:My sexy new project!
 

gixxer ;)

Re:My sexy new project!
 

He sounds a bit drunk.

Re:My sexy new project!
 

yes, they are off a GSXR 1000. they won't make much of a difference (if any), in the torgue curve, but i'm not really to concerned with that. i'm building them for a "cone racer", sos throttle response is my biggest concern (but x-tra HP is never a bad thing)

;D
