Yet another turbo build...

I believe that for sure. From that stand point its a total sweetheart to drive on the street. I love tight converters. I was really referring to a slower spool time.
I mean something in the ball park of a 220/220 114+5 should be able to give you more RPM while not hurting your spool time that bad.

Decided to go top off the tank with E ($1.40/gal !!) and go for a little ride just to settle everything in.
Well, I said screw it and decided to romp on it. Not the smartest as I wasn't logging but whatever. Anyways, thing is an absolute ******* monster. Eboost was showing 20.5 and 20.8 psi on 2 3rd gear pulls from 80. Never felt this truck pull that hard. 20-21 psi should be right at 900 whp. Same WG spring that gave 17 psi on the last turbo. Boost controller is at zero. I'm actually scared to open up the DP dump pipe and that will probably up the boost a couple PSI. Should be nasty at the track.
Oh, and I forgot to add, the spool up on this turbo isn't much different than the old one at all. I can already tell the restalled converter is working much better so I'm sure that's part of it.

Tune is setup conservative already for those boost levels, but I do need to check and see what the AFRs were, so good point. Also, the E gives extra margin for error....the way I've run this motor in the past I'm certain on gasoline it would have been in pieces long ago.

Some of those useless gauges would have been handy right about then
sure beats the hell out of having to go back and dig thru logs every time you want to see what something is actually doing.

Atomic was correct (as usual). Fueling needed some loving but got it in line and man, this thing pulls like a beast on the highway on 21 psi.
Injectors went from 86% IDC on the 130 trap run to 104% now. My IATs are only rising 5-7 degrees over the course of a pull, so this turbo is much happier than the last one in its efficiency range.
One thing I noticed about the new converter....my 80e shifts are softer. Shouldn't the shifts be more pronounced with a tighter converter?
Also got this turbo blanket on. Thing is HUGE. Seems to be made for a full frame thumper turbo.
