Tire doing work

[Martin0660]

Still to be determined ....i need to make up my mind soon

I can't believe those don't spin on the rims. Hopefully no warped head. Is that an issue with the 2.3?

[Martin0660]

If mounted properly, they won't spin, these moved about an inch over 30 passes.

what happens is the boost pressure lifts the head, sometimes it seals back up, sometimes it pushes the fire ring like this time. Head and block are dead flat. A 2.3 head to s like 4" thick so warping isn't our biggest issue

Mason Dixon ate the engine in my Cobra. Sounds like you got out way cheaper then I did.

I was using my gopro in the same way to get the Cobra to hook up at the FLDs. I did learn one thing on the placement, you may want to move it up just a bit so you can watch the fender gap.

Indeed good air will test your tune up. This was the 7th pass of the day and the DA had swung back to where it was much earlier (~600')

I have other videos and pictures that I knew what was going on there. I also knew it was crushing the tire on the line, but wanted to see what it was doing out at the 1-2 shift and a little further. I changed over to my wheels with tubes now ... the car was just starting to get traction when I shift 1-2 and it upset the tires again. Thinking the tubes will stiffen them enough to help that since it is all before the 60' block (3.22 1st gear, 4.30 rear gear). We will probably get to see Saturday at TnT.

IF the head warping isn't the issue, why is the head lifting not uniformly?

(semantics :) )

So you think clamping force needs increased? Can you drill and tap the block for a larger head bolt?

[Martin0660]

If you love the k at the gasket, I propose it is lifting uniformly (not warped or bent) but from back to front . The rear of #4 is the first failure and the fire ring is pushed back. That allows cylinder pressure to the coolant passage. That pressure pushed coolant through the cap and out my overflow, but also pushed in on the fire ring on #3. The head lifted at #4 and lost clamp load across all 4 holes, but more at the rear 2 holes ... Hard to type, but it lifted on an angle from rear to front.

The last time it did this it did the same to #4 but less, and there was only slight chatter on the #3 fire ring that didn't fail.

I measure the the thickness of the fire ring 8 places each hole every time I have one off. Clamp is very uniform until it rattles and does this and that area of #4 is the weak point ... This is a race gasket with a pre flattened hard fire ring ...

previous gasket failure 2 years ago (I ran out of gas at 1,0000' and sneezed it).



there are a number of things that can be done with fasteners, but they are generally the wrong thing with these engines .... I can add a lot better / bigger / stiffer fastener but then the deck distorts. I am running a TTA bolt like ford did with the later 2.3's ... Indeed it will let the magic out, but a 2 hour gasket change an it's running again. Make it stiffer and it hurts hard parts .... I just need to stay on top of the tune up. As cool as it was, ALL the timing was in (no MAT retard on top end) and it didn't like that ... That ok 2 degrees out from 5600 up now and it should be happy.

[RUTHLESS]

If it only takes 2 hours to change ahead gasket I say leave it alone. Heck it takes me a day to get my turbo kit off and another to get the engine out even before I can pull a head. lol

I'm guessing that's another reason Bob likes the 2.3

[Martin0660]

This one actually took 3 hours ... Added helicoils to 2 hot side bolts that was "soft" (holding but couldn't be cranked down) and my F'ing crank pulley was stuck and we screwed around for 45 minutes getting it off. Normally I can work around that but needed it off this time to try a new style timing belt ... We bumped into another application Gates Kevlar race belt that will work with the late model round tooth set up ...

Lol, I have to say that I'm pretty well over the 2.3 platform ... The issue is, I'm too far in to get out without fire saying everything for pennies on the dollar ... When the right oportunity, or very bad mood comes along, I'm moving to another platform

[JeffreyCole]

Track rental?

I am going to go to the regular test and tune Saturday.

I would say you should build a fiero, but you launch so hard it would probably flip over backwards and put the oem fire out.

[Martin0660]

I should of said I'm over unique / different / non mainstream builds, lol ... There seems to be a reason the " path less traveled" isn't a highway, lol. I respect anyone doing it their own way, but there sure as hell are easier ways.

regarding the fire joke .... I run a microsquirt EMS on my junk. When I first started with it, a number of the hard core guys laughed and said the injector drivers would over heat and burst into flames ... So in the 2.3 circle, a number of us joke about running a flammable EMS, and I usually close any discussion about mine doing a new trick with it being a good day that my microsquirt didn't burst into flames.
