2021年10月8日 · But I would also probably do a bike ITB EFI conversion before trying bike carbs. The literbikes all went to EFI over 20 years ago so excellent EFI stuff is insanely cheap and carbs are starting to become 'old'.

GT3 usually runs with GT1, which is the amateur version of the SCCA Trans-Am Pro series. 800+ hp tube frame cars weighing 2700lbs come up on you very quickly when in a fully prepared GT3 car, let alone an ITB car.

2011年2月5日 · One of reasons you don't see ITB on more production cars is that you give away a free source of vacuum. The whole engine tuning, PCM tuning, etc- can all be overcome.

2023年3月1日 · I just Got my Itb's today and can live without IAC after the install. Might get around to it some time but its probably not super important. I probably wont get to putting this rebuilt engine into the car until summer.. Plan is to get it running first on the old known good carb, then swap to megasquirt. III with the EFI ITB's

2015年11月9日 · I got the car initially running and driving using Alpha-N, then switched to the ITB hybrid mode. If you have a clean MAP signal, this will work OK for low throttle openings and load. Tuning the transition to Alpha-N took a lot of logging while slowly upping engine load at …
