Arg. Not quite. This is verging on rediculous, but it is the truth. You know how the title says "Running again"? Well, not so much.

My dad blew the headgasket a couple days ago. Compression now looks like this: Cyl 1 - 0, Cyl 2 - 20, Cyl 3 - 120, Cyl 4 - 10. The head lifts a little more than the gasket can handle when you do a long pull and you're making lots of power. We will probably install a modified headgasket with more layers in order to handle high boost. I really really want it to run for more than a couple weeks after this fix. :lol:

Okay... This time, we put it back together with a custom head gasket, trailer it to the dyno shop, get a nice crisp printout (suitable for framing) from the dyno documenting the crazy power output of this thing, and then park it. That way, when we need to move it out of the way, we can at least start it up, idle it around a little bit, and shut it back off.

It's crazy.

Not yet. Too much stuff going on. The car is under a car cover in a storage unit right now. After I fix up this '98 Plymouth Neon that I'm working on as a project car to sell, we'll probably dive into the rumblebee. Eventually. I'd like to have it running by spring time.

No. I have ARP head studs.

It was detonating some too, so that combined with very high cylinder pressures can kill a gasket pretty quick. I was planning on detuning to avoid the detonation, but then I never got around to it...

And it was a Fel-Pro gasket...which are good gaskets, but not top-of-the-line. It needs a Cometic gasket when it gets replaced.

Actually I was thinking a +.010" Mopar gasket would do nicely. Cometic makes several random gasket thicknesses as well, but I have no idea where to find them. And I think mopar might be better anyway. Plus I'm not really a fan of the fluoroelastomer coating...

Yeah, that sounds good. I didn't know those were available. Where do you track that down at?

PS. We're moving your car out of the storage unit tomorrow.

I ran a TON of boost through mine with a fel-pro gasket. There's either a torque problem, a surface problem, or a tuning problem. There's nothing wrong with the fel-pro gaskets, even if the cometic ones are better.

I'm going with a combination of torque and tuning. Not enough of either. Actually, just too aggressive on the tune for that kind of driving. (the gasket blew at about 120mph). And the head probably wasn't torqued quite tight enough.


Hey Erick, what do you think about using a Crane 14 in this car? Josh and I were just talking about it today, and are probably going to try it out.

Wait... I thought that the Crane 14 was more of an "all motor" profile. And not so compatible with virtual displacement. Won't you have to do even more tuning "gymnastics" to make a Crane 14 work with the turbo...??

Yeah, I was under the assumption that the Crane 12 and Comp 400 were the most ideal boost cams due to the lack of I/E valve overlap.

The shorter exhaust duration on the 12 does help spool turbos sooner, but the combination of a small turbo and a head that flows as much as a 6-cylinder engine, quick spool is not a problem. I wouldn't mind if boost didn't come on till a bit later actually, and the 14 should do that. It should shift the powerband higher, delay boost a little, and probably increase peak power output.

I have a crane 004 I'm willing to trade for the 14! It's an older version of the crane 007, which is listed on howell's site as a high rpm/boost cam. It has the same lift as the 14 but with more duration.

UPDATE

The car is going on a road trip to Colorado. :cool: On a trailer though... along with some shiny new Wiseco pistons and other parts. Then, after it's put back together, I would like to properly use it's awesomeness by driving it to Carlisle this summer.

I'll take pictures of the trip this next weekend and post them up.

Sorry, wasn't paying attention. Good cam if you plan on revving high, like you said. How efficient is your exhaust manifold/turbo? It's a lot easier to run cams with overlap if you can keep manifold pressures down. If you're on a log with a teeny little exhaust side on the turbo, I wouldn't do it. The reversion just would take too much RPM to overcome, and it would be a dog until suddenly the reversion goes away.

I have the luxury of using lots of overlap in my car because my turbo is so huge and I'm running around 18" equal length runners. On my old setup with the log and 16g, I would have gone with probably the comp400, but if I were using the same stuff I have now on the SOHC, I wouldn't hesitate to use a much bigger cam.

where can i find a thicker mopar gasket?

You can call a Dodge dealer, or Fel-pro makes a .010" thicker head gasket. Cometic will custom make you a headgasket that is (supposedly) reuseable, and they'll do custom sized ones.

It's a stock TD04 turbo, but a ported manifold. On the verge of being too small for the 14. But i suppose we won't know until he tries it. I think we've learned from our mistakes thus far, and the engine should stay together this time. Meaning, we can get it to a track and the dyno again, and see what the numbers are. After that if we're satisfied, it's my personal feeling that it needs a bigger turbo. Something that will make 400hp. The car is just a toy now anyway....so why not make it a crazy toy. :thumbup:

Yea, I'd probably go smaller than the 14 if you plan on keeping that turbo. If you're going bigger and putting on a manifold with runners instead of a log (to keep manifold pressures down close to the head) then it would be good.
