That doesn't suck.

Keep in mind that this picture is an old school CARB picture. CARBs can't infer load based off throttle angle as venturi effect requires a pressure differential aka vacuum. It's also from the day where hp per liter sucked, so the numbers are pretty low. All in all, it's a great chart if you figure it'll direct you to ITBs that are way too small for your engine... which is still larger than some of you asshats are trying to run.

So how much does one of your B-series itb sets go for Chris? My buddy with the 92gsr's been going on non-stop about how he wants itb's in the worst way. I swear to god if I hear "Toda" one more time... :7

just got a set of hayabusa 1300's. Kids dont ever get involved in all motor stuff its crack and not that great.

Re: The ITB info thread.
 

Haha...tell me about it, I've been looking over my all-motor budget and the small amount of parts that I've bought with it just to try and squeeze a few extra ponies out. I found a set of gsxr 1000's TB setup on ebay, I'm gonna try and get them just for a mid-month project. Even if I don't make any extra power (which I highly doubt it'll do, but you never know) it'll be a learning experience. I'd rather say I tried it and learned from it than just read about it and just repeat it like the H-T assclowns. :1

Re: The ITB info thread.
 

well the busa's are suppose to be 46mm at the plate which will support plenty of power. I was always doing some researching and there are bike companies that bore them over to 48mm which is well more than enough volume for a typical 200-220 whp ls/vtec



The ae101 itb's are also a route I have thought about trying since they are flanged. This is the platform toda uses for their set ups.



48mm busa's would be very nice on a mild compression b20vtec

Re: The ITB info thread.
 

04-05 cbr 1000rr ITB just measured them ;)

velocity stack < 50mm tapered down to 44mm at the plates, then tapered back up to 50mm > injector side.

Re: The ITB info thread.
 

04-05 cbr 1000rr
upper and lower injectors are they same part number 16450-mel-003

Contacted factory pro today with some results the injectors flow 98ml every 20 seconds at 43 psi

So, that makes them 294cc/min injectors at 43 psi
So, that makes them 315cc/min injectors at 50 psi

you knwo i never thought about it but it would be kind of nice to see an itb'ed 4dr ek.. i had thought about the S2 mani but i dont know now.. i know it would be a big pain in the ass but could it be worth trying on a bone stock y8 probably not but humor me anyway
