Think I've got Norbs beat on this one. Blew both sides to sh!t. Appears the culprit was a faulty crank sensor. Nothing better than working in a shop with an electric overhead hoist and air conditioning.

Well done! How did the crank sensor cause that?

Wow. They're not supposed to look like that, are they? Did you blow out #3 and #4 or is that someone elses carnage?
Blew the two middle cylinders.

I was discussing it with Norbs...and our thot is because the crank sensor was bouncing around...that the timing shot to the moon. Erics chip was on the default setting...so other than the alky shutting off...then I'm at a loss to explain anything else. I started off the year with a new Racetronix fuel hangar and pump as well.

Those gaskets won;t take the abuse as cometics......time to upgrade to a fast with a JS knock box and you can put your foot into it with knock and not hurt a thing....

That my friend is not a crank sensor issue, if it was bouncing around you would have a had a very tough time starting it, if it would start at all. You made a pass before the carnage so that kinda rules that out imo. A couple things to check for:

-Check your harmonic balancer and make sure that the reluctor wheel hasn't moved
-test your alky pump by flowing it into a bucket
-check your grounds on the car
-probe the wires going to your cam sensor (verify its doing what its supposed to)
-have a look at your wastegate and make sure its functioning properly
-I would say check all your vaccum lines, but the motor is already out of the car.
-check your connections going to your fuel pump and alky pump

Almost looks as though you popped a vaccum line off and it over boosted, or your alky never turned on. I am assuming your running 20 psi.......... Can't see timing doing that at that level so early into the pass. Keep probing, something else caused that, I can assure you of that.

Please post a pic of the crank sensor, for further investigation.
Norbs it is the original one form 87 with the metal case around it.

Is there a rev limiter on your chip? ECM cuts fuel alky still sprays you know the rest.

It looks like you're drowning that thing in fuel. Lots of carbon build up.

I think you're running more boost than you think. :wink:

Drowning in fuel...no. Spark plugs are normal...and the wastegate hole has been opened up. Boost is rock steady at 20 PSI. Thanks for your input tho.

I have a shift lite to let me know what's going on.

I want to see if the bracket is bent, if not its some other issue, what did the wideband say?
The bracket that the sensor sits in is fine. Da' Bum don't need no stinkin' WB.

Heads are back from the shop: Magnafluxed...pressure tested...and a minimal skim to straighten 'em up.
