#931 dragstrip result: blown turbo

So last saturday I went down to JMFabrications to do some major work on #931. Brent is a very good buddy of mine, he's the guy that makes the JMF intake manifolds, obviously an expert fabricator. So we spend about 16 hours saturday to sunday installing a 60-1 turbo, T3 tube header, fabricating an o2 housing, external mount, dumptube, as well as all new intercooler pipes and modifying the existing fmic core endtanks.

Last night I took the car over to Island dragway to make some passes hoping to hit 11's and maybe 120mph if the planets aligned. This was to be the last day with #931 for me, as Im going to take almost all of the mechanical parts out in order to rebuild a better GVR4 #139. Was really hoping to have the car go out with a bang.

Ended up making one semi decent pass: 12.30 @ 112.5 with a 1.73 60'. The other 4 passes were utter junk (13's @ 108 to 112). The car wouldn't spool up well, horrendously laggy between shifts. Even on a 6000rpm two step launch it would barely make a couple psi of boost. Barely any better than the car ran with a 16g at 23psi even though I was running upwards of 26-28 psi on this 60-1. :banghead:

Here's what I ended up with:


Notice the two cracked off blades. Grabbing the nut you can feel about 1/8" of in/out shaft play, the comp housing is full of oil, and the wheel has ground a big groove into the comp housing. Yeah, that explains the very poor performance. Guess Im going to hunt around for a 50trim t3t4 or something a bit smaller than the 60-1 to replace it.

The turbo and header came of GVR4 #828 that I parted out earlier this year. Sucks as this is about the 5th major thing that came off that car either broken or not what it was supposed to be. Oh well, buyer beware. Glad this turbo ended up failing on me instead of being sold in the partout and having a pissed of customer. :?

Anyway, not what I was hoping for on #931's last day with me. sux.
