I have been running 45 dells on 2270 with 34mm vents. Not sure if it was the cam choice (163/86b0, but it was much easier to drive with than with the 38/39 vents.
I was going to gut my spare dells for this project, but I think they are worth more in the box. So, for street 2270 what size motorcycle from wich bike tb should I be looking at for a first build? Thanks in advance, Carlos |

Hi,
Just wanted to update this thread with what I know at the moment. I don't think there is any measurable difference in volume between a 1.8 and a 2.1 waterboxer plenum, except the throttlebody mount. waterboxer is bigger, but not big enough for my volvo TB. I am going to setup for the 2.1 waterboxer plenum. I think the overall volume is too small for 2270, but I am prepared to live with it while I cobble everything together. I always expected that I will have to do a custom plenum similar to what Mark Henry has posted on this thread. If you want to post some empirical data regarding plenum volume and performance feel free. Dont post internet heresay.I have cc'ed all of these plenums. I am willing to discuss "informed opinions". I'm trying to learn something. Carlos |
