ITBs for my half bridge. Yes, this post has pics

-xlr8planet- · 09-14-2008, 12:09 AM

This are ITBs from a CBR600RR

Surprise, they came with

- TPS
- MAP
- WAX ROD (for cold idle)
- Manual Adjustment knob, for idle.
- 8 denso 12 holes injectors (I believe they are 190cc each)

This babies are the shitza!

I´ve read they are 40mm, but at the top they are 45, and at the bottom 42....

I dont understand how you measure this stuff

those 4 TBs have around as much surface area as two 56s actually.

Whizbang · 09-24-2008, 09:12 PM

but being how air flows, two 40mm openings with flow worse than one 60mm opening

Interested to see how much power is possible with those T.B's
Just for reference EFI hardware 50mm T.B's flow around 650-700cfm max per throat. I've had good experiences with these T.B's on both bridgeport and PP motors
