TitaniumTT's I hope I make it to DGRR '09 Build

[TitaniumTT]

So motor number 3 is coming out and being cracked open. A not so brief summary of the last 40 hours

Woke up early yesterday morning, went to work, came home late, paid some bills, reserved a hotel in Bethleham PA, spent an hour on the phone with a good friend discussion paint, spent an hour on the phone with a woman, got into the car around 10 ish..... I think. Dropped the fuel tank, changed the sock, for the third time, cleaned the main filter, swapped tanks, got everything inspected, double checked, running great, took all the old gas and dumped it in my boat, ran to the gas station and put 5oz premix in a 5 gallon jug, added 3 gals gas, put that in the car, drove the car to the gas station, picked Roen up in Queens around 3 in the morning, drove to PA and got to the hotel @ 5:30ish..... Roen PASSED THE FUCK OUT soon after the PA border and it was all I could do to keep the hysterics down as I watched this bobblehead in the seat next to me bounce around, snore and drool for the better part of an hour. The bastards canceled my room. So we had breakfast, grabbed a LOT of coffee, a few Red Bulls and headed for KDR - early for once. So we hung out until 10:30 until we strapped the car down. I asked Dave if we could do a compression test before we started on the dyno just so we knew. I was heartbroken. Front rotor is screwed with 3 bouces of unevenness with the low being 101 and the high around 113 and one in the middle. The rear was PERFECTLY even but low at 115 I think. I haven't slept in 40 hours incase you didn't realize.

Now, after the motor had some idle time I compression tested the motor and it was ~125F & ~130R. The compression should have gone up. The only thing that we can think happened was the seals warped or something bad happened during th high 13 AFR 20 PSI spike. The 15 PSI spike made 346 @ 4800.

Dave and I spent HOURS UPON HOURS today combing through a bunch of different datalogs and the map itself and there is NOTHING in EITHER that would cause the motor to be damaged, save those two pulls last week.

Inspecting the plugs showed really nice rich running evenness and the results of a healthy amount of premix becuase I was over oiling her. 8OZ in the tank plus the OMP.

What we think happened was the epoxy coating in the tank that claimed 3 socks and 3 filters made its' way past the filter and into the injectors. Pinning one of them and allowing a lean run condition. The Closed Loop Lambda is set to allow for 20% enrichment and 5% enleanment. During the dyno pulls last week we were seeing high 13's. This was really becuase of a lack of fuel pressure. What might have happened was the front was way lean and the rear dead on giving the average of 13.9. Not to mention for the last 1100 miles when the L was pig rich, the front could've been lean and the rear WAY rick. We'll find out soon enough as the injectors are going to Tim Marren tomorrow morning so hopefully by Friday I'll have an answer on the injectors. They are being sent labled so if his says serial #whatever of fucked, and can say, yeah, that was #1 secondary, that killed the motor.

With luck I'll have the motor apart this weekend and we'll be able to see what happened and what needs replacing. I'm so depressed, 4 motors in 4 months WTF?!?! I think Dave is almost equally dissapointed. He said again today if there ever was a car that could make 400RWHP sequentially, it's this one. Again, Dave is a fricken saint and a joy to work with, even under these circumstances, I can't say enough good things about him.

On that note, good night and sig changed.

[TitaniumTT]

Oh yeah, for Bill. A few maps/datalogs

that are apparently way to big even when zipped to be uploaded. PM me an email addy pal and I'll shoot them off to you

If I read this sooner, I would have gone to KDR to see your car. I guess you'll be going back to KDR again, so maybe I'll get another chance to see you. I've been following your build from the beginning, and it is truly impressive and makes me want to build my car up to your level. I'm on my 4th engine too, so don't feel bad. I probably had the same mileage between builds as you, but you had it in a much much shorter time period. I finally got everything sorted out on the last one, so don't give up.

[TitaniumTT]

Thanks for the compliments. I'll actually be @ KDR on Saturday. I'm going to rock an allnighter on Friday and toss the keg in my truck and head out there so Dave and I can tear the thing down to see what the EFF happened. With any luck by the end of the holiday weekend I'll be breaking in engine #4. I'll be going back for a dyno soon, hopefully in time to make an Auto-x on the 12th, skeptical, but definately in time for Pocono on the 20th. Keep checking back man, I'll be back to KDR @ least 3 more times in the next 4 weeks. Dave is just the man, that is all.

Good gawd!

4th will be the charm, I'm going to lay down Masin's law on you now - " you're not allowed to blow anymore engines!"

This one must be exceedingly frustrating because of the fact that its not dead - just weak and you know it. If the thing idled on one rotor you'd likely be much happy about pulling it apart!

Keep it up B - the car will find its chee.

"and on the fourth day he made another rebuild. And he said it would be good. And it was good."

[need RX7]

Good luck man.

I should hire a minister to sprinkle some holly water on the block as I'm assembling it. So a good friend of mine ( who's Jewish) dropped by today to lend a hand pulling the engine, breaking it down to a keg and getting it in the back of my truck. We're wrenching away and I said, "There's gotta be some bad joo joo in this shop." He replied with, "what, another racist crack!"

Thanks, I'm in good spirits though. Picked some sludgy shit outta the #1 primary injector and 2 of the three studs on the primary turbine either gauled or stripped on the way out. So I PRAY that the housings/irons/rotors survived.

[TitaniumTT]

So I gotta toss out a HUGE thanks to a close friend of mine, Sunshine on a few forums. We might be putting an LSx in his TII but he still has love for the rotary. It took us four hours from the time I drove her in till the time the engine was in the back of my Jeep. Full damage assesment on Saturday.

[MaczPayne]

Perfection is fighting against you! You're no stranger to challenges though

[TitaniumTT]

No I'm not. I have a defeat complex. I don't know what it is, therefore I do not know how to accept it.

I ordered a second TCA today from my Motec guru so I can see F vs R egt's. I don't think it would've saved this engine but I'll be logging them from now on. I told him what happened, how long it took us to get the thing out. His comment, "You're getting too good at this. You don't need anymore practice so stop it."

Le sigh, you're all right. Lets hope this is the last one. Lets pray, lets sacrifice a few virgins..... maybe. Does anyone do the pube thing? Maybe I will this time.

[vex]

Pube thing?... Good Luck B, I'll be tearing out my rear end tomorrow and putting it all back together later on that day. Hopefully that will solve my vibration problem. We'll see though. GL

[TitaniumTT]

Yeah, drop a pube in each housing when assembling for good luck. I've never done it, wondering if I should.

[classicauto]

I actually kissed my rotors during my last assembly. Its holding up well, maybe give that a shot

I am gonna fucking MAKE OUT with this engine build. Tongue in everything!

Damage assesment - warped Apex seals

DAMN! You warped RA Super Seals? You definately went lean then. Those injectors were the problem right?

[TitaniumTT]

Sounds good to me. So I'm at KDR right now waiting to see a 500WRHP 500R run.

Damage assesment - warped Apex seals. Everything else is PERFECT. Already ordered new seals and will be ordering new side seals on Monday. I'm leaving the e-shaft, irons, bearings, stat gears, and rotors here for Dave to Cryo. Hopefully pick up before the holiday weekend and start my own fireworks on Monday. Lets hope.
