Not much matters and the rest doesn't matter at all.

  As usual, problems at El Mirage. A short connector was missing from the longer connection for the F.A.S.T. EFI, so unable to communicate to engine. We decided to run anyway and hope that tune was right. FAST EFI will correct air fuel ratio 20%.
We recorded the run and will be able to see boost, rpm, blower air temp, throttle position, ECT as soon as I can locate that
connector.

 We made a run out of the 200 mile lane about 60th to run. Sounded good Troy didn't full throttle it until 3rd gear then engine
stopped short of finish line. Haven't looked at video yet to see how far, but Troy thought about 1/4 mile. Time of 147 coasting through
finish line. Troy though it felt like a broken blower belt but when we took off the hood, belt was fine. A small burst panel about the size of a quarter was blown out,[ there are 6 small burst panels on Wilson burst plate]. Took off valve covers and found broken exhaust rocker arm at #5 cyl. Hoping just from fatigue as rockers are several years old. plugs looked great but #4 looked a little oily, and compression test shows down about 20lbs.

Upgrading to Stage V top fuel rockers [ big bucks] :cry:

Car looked nice and clean before we went to El Mirage.



After we returned not so clean.  I believe the dust is worse than the salt to get off the car.










And the broken rocket arm got the worst of it!

I give up.  the folding chairs are for paying spectators, to raise spare change to buy beer?

The folding chairs are for playing "Musical Chairs" to see who gets to run the power washer next?

The folding chairs are for the rest of the parishioners who didn't show up for services at the car wash?

  The chairs get dusty along with everything else. And after washing we hang the parachute on them :-D

  Troy pussy footing it just to make it all the way thru and then a rocker arm broke :roll:
  Bought the missing pigtail for the EFI and will know throttle position when we download.

  Good pic of why it's called El Mirage at end of run.

Luckily you can leave the dust on for a week or two and the car will still be there when you get around to it.  Not so with salt.

We received our new rocker stands today, they're a nice shiny anodized blue.  Just waiting on the rocker arms and then we'll be back in business!

John,
Are you going with forged steel rockers?

 No, the JESEL forged steel exhaust rocker is $325, intake $278 each :-o made for top fuel with lots of nitro and opening into a lot of pressure. $4824 + tax and shipping almost as cost of a KB block.

Over kill on application and pocket book. Going with stage V cast stainless, top alcohol. Much more reasonable and we don't rev
nearly as high as top alcohol.

The stage 5 rocker arms have arrived.  Now it's time to start the inspection process.

  We got the GoPro in car video up on my computer Sat and Troy took a pic of video with his I-phone.
  We were busy yesterday with his daughter ''Peyton's'' 16th birthday party and 50 + guest :-o
  So hoping he'll have time to post it soon.

  If you look at the throttle on left side of hood, in the video to be posted, you can see it never goes out of site.
  You can tell when rocker arm breaks, engine quits, and it takes 10 sec. to cost thru finish line at 147 mph.
