Megabusa nearly done, few questions
Hi All,
Thanks to Danny & Steve at MK I now have a working wiring loom for my GEN 2 Busa engine fitted to a westfield Megabusa. I got it started for the
first time last week and now have a few question I hope you guys can help with:
1. I had to trim the rubber air inlet trumpets slightly to get the air filter (sausage type) to fit over them. How fussy are these engines about even
air inlet flow? If it's a big issue, SBD motorsport do a taller filter and I could source some new rubber trumpets.
2. I have currently tied off the IAP sensor beside the air filter, Am I best drilling a small hole and fitting it to the backplate so it gets a
genuine reading?
3. The pair control valve air intake pipe is sucking air constantly, I've heard some people blank it off but it will help with emissions so I
may do that after the SVA. Would this constant air into the exhaust be the cause of the cat glowing red hot after a short run? I'm not using the
HO2 (lambda) sensor. The Idle speed control air intake pipe is also constantly sucking, is this normal?
Thanks in advance,
Neil
