I think it was more helpful than your answer.

If you got no experience with 20B's, why you sticking your nose in this thread?

Did you remove the sleeves from the rotor housings or use 13b housings?

nice hp!!!! How long will that motor last running at 16 lbs?

sillbeer 05-10-2005 11:22 AM

With good tuning it should last a long time @ 16lbs. This was with fd housings. As soon as I put it back together it'll be a little over 600. The current injector configuration was holding me back. Primary 550's and secondary 1000's. I picked up a k2rd rail and some 1600's. I'm also going to install a water injection system for it. It'll help the piss gas I have to run here in the states. I don't plan on running race gas in it.

That's one advantage of europe, we can't get anything lower then 95 octane, usually 98.. but on some stations you can get some really high octane fuel:p



Does afgas has an advantage over regular fuel when it comes to detonation prevention?

Just got word from the shipping co. that my 20b will be here tomorrow!! JR plans on doing some mild porting .....if the motor looks good inside......if we have to tear it open he will be a bit more aggressive. Planning on running just 8lbs or even just the spring most of the time. Once it's running will go from there. I'll be posting pics.....JR does sweet work so I'll post as it gets built.
