FC3S Murray's never ending build.

[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?

[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.

Damn right, that's good to hear

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

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.

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.

[RETed]

1600F - 1700F is way too high for 2nd / 3rd gear + aux injection...
Unless you were boosting like 20psi+?

I would think it would be more in the 700C / 1300F range, especially with the aux injection kicking in?

What kinda spark plugs are you running?

My mistake Ted that was in first gear and AUX injection kicks on for a split second(around 5K or so).

I was boosting 15 psi

Sean i got your back 100% You deserve some fun dammit!!!!

[FC3S Murray]

Thanks homie!

[Rotary Inspired]

Ted I know you are big on tuning w/ the EGT gauge and one of the few I know of that are brave enough to use only the EGT to tune. What are you looking for in the logs of the EGT for the cause of this?

What are your thoughts on the cracking of plates. Everything I have seen points to a misfire which causes more strain on the block. I am wondering if the addition of the aux injection could have a cause on this. IMO there is not a huge need for aux injection at the 400 hp level. If you proceed upwards getting close to 500 is where it would be good investment.

Always willing to listen. Thanks in advance.

[project86]

I believe he chose aux injection because of the octane rating in the gas here... at least that was part of the reason.

[FC3S Murray]

Yeah...91 octane here.

Plus I really just wanted the knock deterrant when I started to push 18 psi.

[Rotary Inspired]

I understand completely. I run 91 here on 17 psi on the street w/ no A/I but everyone has a little different thought on it. That is why I was asking w/ Ted thought. I like to hear others opinions and compare to what I have seen. I don't know another way to learn more.
