Hey Joe, running a type-k thermocoupler that is mounted dead center in the stock exhaust mani. I've got to check my setup as those egt's seem rather cold meaning that the timing is advanced which I don't think it is. I guess it's possible that the L is cooling it but I'm not sure about that much..... we'll see on Wednesday when I'm back on the dyno.

BTW - I'm happy with the fuel curve for now. It's good and safe. I did some pretty light sequential tuning. The transition needs alot of work as the pattern is like 7-5-7 but holy shite do they spool and FAST. Wednesday should be fun.

I LOVE the software. I'm a very visual person and the datalogs are a dream for me to use. Can't say enough good things about the Motec stuff

Damn, makes me want to move to a Motec!

Mmmm... RA1's. Those will surely put a smile on your face.

I know, after using the V3 stuff, nothing compares. I really think it's JUST the cost that keeps more people out of Motec's

We can only hope:driving: Depending on what class they stick me in next week will determine if they go on or not. If they stick me in the Novice class, I'll run the Azenis, if they put me in Street Mod, the RA1's will make their debut. I was the ONLY person in SM that wasn't on race rubber and while I didn't throroughly get my ass handed to me, lets just say it was gentle placed on my lap :rofl:

Brian the car is incredible, I hope to see it someday... Also I don't get the plate... O Pistons do you orgasm for pistons or something?

TitaniumTT 06-22-2009 10:44 PM

Holy Bejeezus it's Kevin! How they hell are ya man? Haven't heard from you in a while. Thanks for the compliments man. You may get a chance to see her yet as I am planning a trip at somepoint to Rochester NY for some corner balancing and alinging. You'll definately have to hop the border if we're that close, damnit.

As for the "O"..... check the sig foo! It's a "ZERO," not an "Oh" :banghead: I really don't understand why people don't get that. Even my buddies Fiance asked, "why is it "Oh-Pistons?" Maybe becuase we're dropping an LS in his TII? Dunno, maybe I should pimp slap both of them? Dunno. I don't orgasm over pistons, they generally wet themselves when I'm around............ the ladies too ;) Mr. Spoolin, panty wetter extradinaire :rofl:

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 06-24-2009 11:22 PM

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 06-25-2009 10:50 AM

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."
:lol:

:rofl: 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!" :lol:

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.

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.

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

TitaniumTT 06-26-2009 09:43 PM

:rofl: 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." :lol:

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.
