RX1 s/c at 10lbs lean questions

[rxboost05]

Guys

Got to do some testing. Iam seeing 15.5 at idle with 127.5 mains, clips dropped 1 notch, and pilots turned in 1/4 from stock. I am seeing 13.5 on a/f on about a 1000 ft run across field, rpm about 9000 to 9500. no air leaks and very good fuel. Stopped testing as to do no dammage.Any ideas were i can go from here????

I'm just going thru a similar thing with my turbo. From what you have said 130's will likely put you in the 12's at WOT and 132.5 will get you into the 11's. I was at high 13's low 14's with 127.5 and went to 135's. My new WOT a/f is 11.33 pinned at 8 lbs. As for the idle mine is usally in the 10's. Are you still at 17.5 pilots?

Yes pilots are still stock 17.5s. I will try 130s and the next size larger pilots. As soon as we get snow again i will try and let you know. Thanks for the info, i think this thing is going to be an interesting ride

This is where I wound up- 130 mains 17.5 pilots 15m floats @ 10-12 boost
I showed 10.5-10.7 WOT 11-12 cruising 13-14 at idle this was with 110
VP leaded straight-this year 104 sunoco unleaded-will keep you posted!

No ice anywhere, just 14" of fresh snow with no base.
