Ohhhh I am taking her to Houston to race her Friday night... its an 88/91 turbo built by Jose and folks. We made some fun changes to her this spring (4L80 and upgraded the PT88 to an 88/91). We saw 821RWHP corrected last year and ran mid 9's (had a run or two that should have been low 9's but ran into issues)..

Currently the fastest rear-mount F-bod in the US (that I know of). We want to be in the 8's this year...

Keep in mind... completely street trip.. A/C, factory seats, Power steering, Radio, etc.

If you want to know about the build just ask... cam is a pretty mild cam (cant remember the specs but I can look them up) and its on a built 408 (by Erik Koing)

LMR can make a tincan and a rubberband go fast... so I am glad they are making mine do the same!

Hmm... hotside is 3" (or 3 1/2") all the way back... Manifolds to ORY to Turbo... all wrapped.

Cold side is something Josh (LMR) did very custom.. due to size restrictions we are running dual 2 1/4" back to a 1400HP FMIC (dual inlet single out)

umpossible! rear mounts can't spool turbos that big! Curve and spool will be a lot better in real life.

If they make a divided housing for that turbo get it + a quick spool valve watch spool time be cut in half! My 80mm comes on real fast.

That's a nasty ride.
