Dragging the 6-port turbo tonight
Well, in about 5 hours I'll be drag racing my '87 Sport 6-port (n/a block) turbo at Kaukana, WI. Any suggestions/thoughts/bets as to what's going to break first? Here's the setup:
starion fmic
walbro 255
turboxs mbc @ 12psi
clutchnet 6puck clutch
3000GT rims on the rear w/kumho's
550 primaries, 720 secondaries
S-AFC
wideband with gauge right infront of the tach
Car weighs in about 2600-2700lbs with driver (me)

I never actually broke anything due to boost, but when I was NA I managed to shatter a front U-joint at the strip...Back in the day, I was at the track nearly every week. Nowadays I go less often (since I'm driving the Insight right now).
I think that the input or cluster shaft of your transmission are the main concerns, but as I said, I never actually broke a transmission due to boost. I destroyed two due to lack of fluid (broke an input shaft on the first, totalled the bearings and input shaft on the 2nd). NA transmission is stronger then people think. I would air down my tires to around 10 PSI, do a burnout, then launch at around 8-10 PSI @ 6K.

I plan on taking the launch pretty easy (4-5k feather), as that's the most stress time, if it holds up after a few runs like that, then I'll take it down on an abusive launch.

well, at 10psi I never see over 10.5:1 on the a/f ratio, so I don't expect much from the engine as far as damage goes, i'm just more worried about what else I'm going to murder.

Just got back, good news is, I didn't break anything! Bad news is, my intercooler hoses blew off on every run! I do however have 1/8 mile times & 60 foot, so I guess you can use those. Lemme post them after I take a ****.

Here are the time slips that I've got. The 2nd run was started by a flagman instead of the tree, so no R/T. Pretty much, shortly after shifting into 3rd, and the turbo spooling up to about 13-14psi, the intercooler hoses just kept blowing off, couldn't keep the bastards on for the life of me. I ran against a lightened awd dsm, and had him by about 3-4 car lenghts by the time we hit 3rd (his car was running low 14's), then I raced a GTP with a pulley/header/couple of other unmentioned mods. And he got the jump on me (he ran the flag, took off as soon as the guy raised it instead of dropped it), and was probably at about 20-25mph by the time I took off after, shot ahead, started pulling pretty hard, then boom, blew it off again. Finished the runs in 23 seconds @ 32mph WOT to keep the damn turbo sucking air in so the AFM wouldn't stall my car.
