FC3S Murray's never ending build.

[FC3S Murray]

BAD NEWS.......

Went out today with Kyle(Project86) and did some WOT tuning for 3 hours straight. Did about 20 3rd/4th gear pulls and got my AFR down to 11.0:1 -11.2:1 AFR at 15psi with my 50/50 inj system working great the whole time.

IGL was 11, IGT split was 10, highest knock value logged for the day was 23 in midrange.....at 15 psi and above 5000 rpm the knock values were 3 to 8 sometimes as low as 2.

NEEDLESS to say it was a conservative tune and felt very strong.

Anyway after our 2.5 hours of WOT highway tuning we headed back home to refill the AUX inj tank. Then We decided to get some video of some WOT pulls for the forums.....

We ended up doing a 1st-2nd-3rd gear pull and I CRACKED MY FUCKING FRONT IRON !!

I actually laid off in 3rd gear at about 6000rpm and noticed a big cloud of blue smoke behind me pouring out my ass end......I glanced at my oil pressure and it was slowly lowering as I blipped the throttle. SO I cut the engine off and pulled into a parking lot that was very near.........HAD SMOKE coming out from under the hood SO I grabbed a fire extinguisher and THANK GOD no fire...just smoke. OIL WAS EVRYWHERE.......and after a quick scan of the engine bay HOPING that a turbo oil line popped off it hit like a brick and I thought to my self, "check the front iron"........sure as shit I saw the crack plain as day......



As the motor sits now.....OIL everywhere.......tried cleaning most up SHITTY!!



GOOD NEWS IS Kyle got some video of it being FAST before she broke....he will post it later tonight.


At this point I do not know what to do........I am undecided if I want to part the car out or sell it in whole. I have ZERO time for this now and really just want it gone right now. I need to sit and think for a while.......

Here is the link to the video since i couldnt figure out how to just post the vid. http://www.facebook.com/video/video....14088401944294

Damn Sean..... Sorry to hear that man. WTF caused it? Got the datalogs? PFC's are not known for fluky ign leading to cracked irons.

Buy an iron, send me the keg and the new iron and I'll put an engine together for ya before you sell that car. If you so much as mention "sale" or "part out" I will personally come out to you and stuff one of those intercooler pipes up your ass, then through a turbo at your face, and leave with your Works

Kyle - post it on youtube, some of us older gents don't bother with that teeny bopper facebook crap

ah haha you so funny Brian. FYI its a good way to keep in touch with ppl...



its on youtube now ill post the link......http://www.youtube.com/watch?v=shcOH779fVM

and i wanted to cry when that happened... it feels like someone died. i know i didnt put as much time into that car as Sean did obviously but i helped tune and build the engine and there is some emotional attachment there.

[need RX7]

Ah man, no way . Really sorry to hear about that. I hope you change your mind on selling it or parting out, but I can understand the frustration you're having with it.

I think you should take Mr. Spoolin' up on his offer. Shipping an engine isn't as expensive as you'd think . When I bought my short block, the shipping charge was $105 from SC to MI with Yellow Freight.

Thanks dude but I am at my final straw with the good old rotary. I am going to part out all the rotary components and this may sting a bit.............but I am dropping in an LSx motor. I am already looking at the LS3 crate motor through a Chev buddy BUT I have to research if it is a common swapped compared to the LS2.

A part of me is bummed BUT a new spark of interest has started with the thought of a new platform.

I have TOO much work into the body/chasis/suspension and wheels to get rid of this car that has been in my life for 8 years.

Granted this project will no doubt take 2 years or more since my family comes first and or second child on the way makes that timeline maybe even longer.

I HAVE THOUGHT about another plate but I imagine it will crack again. My logs showed low LOW knock and AFRs all 11.0-11.2:1. I have an HKS Twin Power so my IGN system was firing pretty hot. I think the shift from 2nd gear to 3rd was such an abrupt power transfer that it just caused the motor to twist. FUCK it makes me mad! You go from 20+ WOT pulls on the highway in 3rd and 4th.....all temps great..wtr 82*C AIR 22*C oil temp 180*F and the motor doesnt give BUT you do a quick burst through the gears and CRACK lol.

Sorry for not digging up the info, but...

Was that an S4 or S5 front iron?

it was a S5 front Iron Ted. I mean what else could I use that is thicker?

OH believe me Ransom......I am very discouraged

Ah man, no way . Really sorry to hear about that. I hope you change your mind on selling it or parting out, but I can understand the frustration you're having with it.

[Flash]

Man, that sucks. I've been following your project for a while and I never expected this. At least you can say you went for the gusto. Most people just live with 140hp corollas having never ridden in a car with super-car speeds, let alone build one. I know the out come sucks but I can definitely appreciate you sharing your experiences with the rest of us, 'cause I know I learned something.

I'm sure you'll be able to find a good motor that'll be as fun or more than what you have.

PS, I can't remember if you had installed your new coilovers... review vs your shocks/springs?

[Rotary Inspired]

Dont sweat it man. I have been there. Good news is you only need a new plate. Just take your time and rebuild it.

Are you running any ignition amplifiers? I can look it up but which ECU? Just curious.

Last time I broke my plate was due to a misfire (overly rich due to someone --me-- forgetting to set the rev limiter back.)

Do you have the run logged?

[FC3S Murray]

Thanks for your words Flash, you are the 3rd person to say that to me in regards to going big. Haha the only part that blows is I never got to bear fruit for long .

Man my head is spinning with what to do.

Lets hear it guys............

Pricey, but interesting nonetheless: http://www.h1v8.com/

I'e been (silently) following your build over here. I can truly say you have one of my favorite RX-7's and that's saying a lot because I usually don't like S4's. It really is too bad about your luck.

Fuck that noise. Anyone that I want to be able to get in touch with me knows how to, and I like it that way.

Dude, I will kill you. That is all

With as clean as you've got your car now, it'll take you YEARS to get it to that level with any type of piston engine swap. Having just been thoroughly involved in an LS1 swap I can tell you that to get a clean engine bay and a good cooling system, it's going to take a TON of fabrication and you're going to need to re-spray your bay...... Kyle so that may not be that big a deal actually.

Fuck that noise man, seriously, lets work something out so you can drive the fucking beast this year.

Something else is amiss and I'm not sure what it is

What's your oil pump feel like? What are your oil PSI's? Your AFR's are toooooo rich for my likings and the twin fire might have done some funky things. Is that a re-spark system? If so that could've been your problem right there. I'm a big fan of inductive sparks.

What kind of HP/Tq are you expecting? I don't think you're at the level where pinning is really even thought of as needed. I think something else is going on. Cryo may be the answer for you.

I don't think you need something thicker, I think there's some other wierd shit going on.

Dude, if you set the engine up right, me rebuilding wouldn't take very long at all AND I can get it cryo'ed. Seriously Sean, I'll be able to get your engine here and back to you in a matter of days depending on the cryo stuff. I would without a doubt tell you to rebuild this engine, swap the ignition, lean it out a little, maybe swap out some mounts and maybe a clutch and run it. You've got too much into making a CLEAN as hell engine bay to ditch it all and start all over and not enjoy the car for a few years.... fuck that.

You went big and something strange went wrong. That shouldn't have happened I'm telling ya man, I don't think you're at the plate cracking tq levels yet. Lets get her back

I told you what to do, PM me if you wanna work something out.

Fuck that, 245ft/lbs of torque? That's laughable. High revs and weight yeah, but no real power to brag about.

[RETed]

Did I miss the part about the EGT (gauge)?


-Ted

[TitaniumTT]

No, we're still wainting on the logs

[FC3S Murray]

In regards to the EGT's: They are not linked to my Dtadlogit....they will not interface with the damn thing. They are simply stand alones units. Kyle witnessed the EGt temps on earlier 2/3rd gear puls and they were in the high 1600*F/1720* F range.

As for my logs when we did the pull in the video, my laptop died 15 mins before that. I did some last minute AFR corrections and logged those before we lost computer power.

So unfortunately I have no data from that specific pull......just 2nd gear and 3rd gears pulls from maybe 30 minutes earlier with that map being unchanged up to the front plate cracking.

The recorded data in the previous logs are what posted earlier. ALL safe parameters.

Brian.....dude you are a hard headed MoFo lol!! YOu are tempting me BUT I have two months until baby comes and I HAVE SOOOO much more shit to finish on the home it is sickening.

PM me with what my cost for this to be done by you will be please.
