Season ending 9.45@145 (added Videos) 
I had the opportunity to participate in a track rental at Woodburn dragstrip today. Below sea level air, sun, mid 50's and Excellent track prep.
I knew this thing would hook on a good track, even though it has the wrong gears, wrong converter etc.
Very fun this turbo stuff. Last year at this time I had just run 10.03@133 with the rat motor. Quite a change huh?
many thanks to all those who helped and inspired me.
Ron

Congrats!
A 60-100 shot of nitrous for 1000 rpm works wonders (or about 1.5 seconds). Will make as much boost as you'd like, and allow you to keep the tight converter. 10lb bottle would last all year. What kind of RPM do you see on the big end at 145?

Yeah, understood on the nitrous. But I don't wish to do that.
Finish line RPM is 6900 by the logs.
My plan is to switch to a 3.31 gear. And possibly a PTC converter.
I'm also out of injector, running right at 100% duty cycle. So I may up those too. Not enough pump left to up the base FP much more.
I'd like to turn the boost up closer to 20. I'm at 15lbs now.

Holley HP 12-1800
56 base.
I am not logging FP
I'm running at 11.3:1 AF ratio.
What doesn't seem to be published is where that pump looses flow. At least I have not seen that data.
Also running the matching regulator. I do not know how much pressure it can handle and still have a linear rising rate. Holley says 70 or 75 psi max depending which document you look at.

Are you running both pumps in the 1800 together, or bring in the other one on boost
I have the 1400, just mounted it yesterday, and the 848 reg-i planned on #10 to the fuel rails, 8 return (running a 4150 style intake w/90 deg adapter) as usual I would have done it diff., but it started out a diff. way, lol
Did you go in one end of the fuel rail, cross over to the other and then to the reg? I have seen it done a couple diff ways, tee in and out
less fittings, less cost, that's the mode I am in now, lol
