garrett equivilant to S91??? I was curious if garrett makes a turbo that is the same size physically as the S91. I have an OFI kit and may have a hook up to get a garrett but want to make sure it will fit.

yes...
Forced inductions posted this pic several months ago
the turbo on the left is the S91, The turbo on the right is supposed to be identical in size to the GT55

That is correct. The GT55 and GT47 are much larger units. The S88 and S91 are very close to the GT42 and GT45 frame. As for power the S91 and GT55 will be very similar with the S91 spooling faster.

Who cares about the 91... LOL 
When will the 98 be ready???
I should have some input on this with the 91mm unit...
I have the center FI-9155 and will be using it with my new 410ci motor.....
after that...... who knows

I don't see 1500-1600rwhp #'s be far off. The FI-X units flow stupid amounts of air from all the testing done and some of our beta guys out there, and they spool ALOT faster then the conventional thumper.
How about a precision 114 billet wheel unit? Fastest single on the planet by FAR!!

I have heard of the cast wheels having problems and they say that you need to run dual BOV's with that turbo also. I think the billett wheel ones have been pretty reliable. Looks like precision is doing a decent job with their stuff. Kolivas with his mod motor with an 88 has supposedly already gone in the 7's on BFG's.
Spooling with a smaller engine may be a little harder but i think more tuning can help that out.I think the tradeoff is worth it. No other single has even come close so far.

I have seen two 114's break locally in the last few weeks...and they both broke on the first pass or two. One was a billet wheel, one was a cast wheel. The car I installed the cast wheel 114 on, I also installed a second BOV. Didn't seem to help 
As for 91's, Our shop car has went 7.79 @ 181-184 on radials with a box stock GT55-91.

Impressive on the GT55-91. Which car is your shop car and what series does it race in?
Looks like they still have work to do on the 114 unit. Wonder if T-Netics has their 114 out yet and how reliable it is? I havent heard much about them.

I hate to say it but, you are wrong with that statement,my buddy Andy Jensen has what i believe the fastest single turbo car in the world at a 6.22 240 in his vette,it has a single turbonetics 106 on it
