[hades]

are you tearing down the motor again?

Yup, the one I'm looking at accomplishes the same thing, but goes about it in a very different way. One that I think will work better given the rotaries heat. So we'll see. I'd love to have it in for DGRRXI, but time will probably be against me.

Someone from handuhtech... bdc can't weld at all last I heard. That is probably one of the worst welding jobs I've EVER seen though.

[helghast7]

see what drives me nuts about turbos is i once read about a turbo being developed similar to what your looking into except they designed it more like the way a fighter jet vectors its thrusters, but ever since then i cant find any information about it, it literally had moving plates that channeled the exhaust gases in the dp

i wish i new what happened to it, it seemed like a very promising idea

I've got to pull it to do some touch up paint work in the engine bay. And I've got to pull the turbo's to port the wastegate. When I do that I'll take the mani off and see what kind of shape the sleeve is in. If the sleeve is solid, I won't. If the sleeve seems loose or if it shifted at all, or if there are signs of an exhaust leak, they yes, motor comes apart again. I've got one good REW housing, so if the sleeve is in bad shape I'll either need to find a comparable REW housing, a comparable RE housing, or take 2 of my n/a housings to Goopy for that resurfacing treatment.

As of right now though, the only things that I need to do to the engine are re-work the harness slightly to add a fuel temp sensor, and change out the intake mani gaskets. Mazdatrix didn't have them in stock so I had to re-use the old ones.... it bothers me.

[TitaniumTT]

Curious more than anything. Plus there is a seperate comp table that I can use to compensate for high fuel temps. Thought being hot fuel expands, less actual molecules, potential to run lean etc etc. Not a big deal unless you're on the ragged edge of the tune, which I'm not, but still I'm curious to see where it goes.

Oh yeah, forgot to add, when I pull the exhaust mani, I've got to add in an EGT probe.

Soooooooo... We finally got that CUCV up and running and I was finally able to start on the FC. First thing.... put the list up on the wall



If anybody uses an Optima battery, they know that they like to die, and die fast when left to thier own demise. I've got a batter cut off switch so that when the switch is turned off, the only circuits with power are the alarm, horn, PW, PDL, and the radio memory. If she sits for a few weeks, the battery is stone dead. Sooooooo, after getting one replaced on warranty I picked up this little gem and mounted it on the wall.



Now, how to connect it to the car? Well, the little kit comes with an adapter that has a pair of aligator clips on them. Ok, maybe.... but that means I need to put the passenger seat forward, pull the lid off the storage bin lid, lean in, clamp them on, hope they don't fall off etc etc etc. Royal PITA. luckily, they have a little adapter that you can hardwire to the battery. Cool shit, it even has a little fuse there. 15A, interesting but I'm not going to argue or try to reinvent it.



I've got my battery mounted in the passenger side bin, and mounted rather snugly. I've got a powerpost in plain view for the various grounds, to bat, to chassis, to jumper, to amp, to fuel pump, and now to charger... cool. Coming off the battery I've got a 2ga cable that runs right to that main breaker. From there it goes to the remote bat switch and splits from there to go to a bunch of different places. So, seeing as how this is already fused, the best place to wire it up is going to be on the line side of the main breaker. One of my BIGGEST complaints about other peoples wiring is when they stack shit on battery terminals. I fucking hate it. I've seen boats sink becuase of it, fires almost start etc etc etc.... One of my rules is one cable per terminal. So it's going on the breaker



And here is the connector mounted on a little bracket that I threw together.

[TitaniumTT]

I mounted it near the battery on the fiberglass uprights. If that fuse blows, it's going to be a royal PITA to change it. I'd much rather be able to easiy get to it rather than take the battery out, maybe even the fiberglass.... so were going to mount up a 15A marine breaker that I happened to have kicking around. I would've rather used a push-button breaker but I didn't have one, and the chandlery store was closed, waytek, terminal supply, delcity etc etc would've been a few days out so I said fuck it and used the breaker. If the carpet trips it I'll either get a shield for it or swap it out. I don't see it being a problem when the connector is plugged it.





and there it is plugged in.... weeeeeee I finally got something done

[TitaniumTT]

Just for fun.... we were supposed to get 5-8" of snow. Finally tally that I measured was 17".... way to go guys. Regardless.... 3 hours of shoveling so I could get the FC out to make it to the dyno on Saturday... hint hint hint.....

That little mound over there is the 'vert under a car cover. It'll be MONTHS before that pile melts to get that car out... damn..





Last night I figured I'd do a little on the FC, then move some cars around and get my truck off the street. By the time I was in a position to get the FC out, there was already 6+" on the ground. I wasn't about to shovel that shit out, couldn't if I wanted to, was coming down to fast, so she sat on the street overnight, and of course I got plowed in. I LOVE this truck, all I did was toss her in 4-hi, rocked back once, and drove out. Then I went down to the beach to play around in some un-plowed parking lots. I tried to get the thing stuck and I couldn't.... I love my XJ.

Dude, this may sound weird coming from someone that lives in Colorado, but I'm SO glad I don't live where you live LOL!!!

[MaczPayne]

Why is 'Touch Myself' only listed once?

[blackedoutFC3S]

Maybe going through this whole thread in one night was crazy... Mmm definitely not. Your car is amazing TTT, the work and dedication are something so few owners have with FC's, glad to see there's people out there still willing to take them all the way. Great build up brotha, I'll definitely be stickin' around this thread to see what else is happening! Love the fab!

I know, that mound is still behind the 'vert, there's still lanes missing downtown... fucking blows. Oh well, what can ya do.

There will be multiple crosses on that before the build is done.

Thanks man, I appreciate it! There will be a ton of shit in the coming weeks for sho!


So I figured I'd bump this thread with what I've done to the car in the past three weeks

First was some playtime on the dyno,
Then I repainted the hood after an unfortuneate incident with an engine hoist and some rocks at high rates of speed.

Then

















I


















Washed
















It.
















And that's about it.... the RX7's vehicular nemisis is taking up too much time, I'll get some pics up of that motherfucker tomorrow. The big push is to get this done in the next 3 weeks so I can rock on the FC before we start getting really busy at work around April...... tight tight as always

Brian what ever happened to the great coil dyno off?

[TitaniumTT]

It's taking place in smaller stages. So far we've pitted the Bosch coils against a $1500 M&W ignition system and then against the Quicksilver coils.

The M&W setup gained about 3hp over the Boschs across the board, but the idle sucked balls. Regardless of what we did, including mult-stike, I couldn't get a decent idle. THe Bosch's idled the car perfectly with a 0 (Zero as in nothing) dwell time and didn't start misfiring until about 3k.

The quicksilver coils impressed the hell out of me. We we're tuning my car when we started running out of time so she was running WAY rich, which is a good comparision in one way. The Bosch's were getting a little breakup up high and still putting down 380 rwhp. Bolted the quicksilvers on and the breakup went away, and she picked up 4hp up high where we were getting the breakup. BUT, there was no difference in the low to mid ranges where there was no breakup. They are a STOUT coil. I was running those with a 3.5ms Dwell time as Chris Ludwig told me to do, he loves these coils and rightfully so, the Bosch coils where set to 2.4ms. So I'd be curious as to if increasing the dwell time would get rid of the break-up.... didn't think of that until after the fact though.... oh well. I still love my Boschs becuase they are so damn small and need such little dwell time. I would love to get the car dialed in and go back and test the Bosch vs the Quicksilver again because I think they are that close. The Quicksilvers I think would be an upgrade to the Boschs if you're running water or meth or you're like bdc and think that running .7L is safe

Now, we also had two RX8's there. One running LS2 coils, the other running the Quicksilver coils. LS2 coils put down 187, Quicksilver car put down 194. Different cars so not really a good test, but I will say I contacted BHR about 'renting' a set of LS2 coils for this test. I told them I would give them all the data I have so they can publish it on their website so they can show an increase in RWHP with the RX8 coils vs the LS2 coils. They told me flat out that they already dyno'ed them back to back and they intentionally did not post the results. That to me tells me that the difference in RWHP between the RX8 coils and the LS2 coils is little to none, so I tend to think that the LS2 coils don't make THAT much of an improvement. Glenn is going to send me a set of LS2 coils when I get my shit together and head back to the dyno. We got another 6" of snow last night so it won't be for a while
