emailed you the logs. If you can figure out how to post them here, go for it. \

We had a high today around 70*F. Tomorrow is our last day of warm for a while I'm afraid. :(

Why is it everyone who complains they think turbos will be laggy goes out and buys a huge one? :-)

At least run yourself an extra 5 psi of boost over what you are, you'll be fine. I'm running ~14 right now and the only problem is keeping the driveline together. :-)

MBC's are awesome, no? Don't feel bad about them being touchy, it's how they are. But they are set-and-forget (though keep an eye on how weather effects boost levels), so once you get it, it's not a problem.

My car's sputtered to a stop for gas leaks or at least gone very lean so many times I can't even count it. It's more scary having a low tire on just one side of your LSD. :-P Well, let's say you get jaded to it. The only time I've had any issues was an oil leak which at least got me smoke. But like you, I ran out and bought an extinguisher, and a second for the garage. It's probably a bit bigger than what you got (but half the size of a typical "household" one).... I think everyone does this, buy one AFTER the first close call, and everyone should get a fire extinguisher if they don't already have one!

Now you're scaring me and have got me looking at Halon extinguishers to mount in my street car.

Be afraid, be very afraid!

I remember the first time, was at an autocross, and there was a puddle coming out from under the car when I got my timeslip. The guy sounded very very worried.

Most (all the major ones) leaks were from the FM secondary fuel rail. Installing the TwinCooler they advised me to pull the manifold support brace, and as best I can gather from the folks I've talked to, people who remove this AND have the secondary rail keep losing the rail. I've been through so many iterations with that thing.... Thank god for MS and huge injectors. :-)

Congrats Pat. At least I have started my install now. Hope to have it together in a couple of weeks.

what miata?

thanks for the email... intresting looking at your logs...
man u got to tune part throttle and under boost a lil u prob drinking gas like crazy.. and the intake temps look good... prob cuz the turbo is big... and man u got some serious lag going on...

also what wide band are using cuz mabye im seeing the wrong afr. but i tryied all of them and the lc1 looked about right.

when u get some full throttle to redline send to my email agian..... intrested to see...

anyways gongrats on the boost agian.......

Yeah, I run my car on the rich side. It likes its' fuel. Runs smoother. Still gets 20-22 city before turboing it.

Yeah, the lag kinda sucks. Hard to say. The power is nice though. I think I'll improve spool up a bit with tuning. I hope. And the wideband reading is bouncy from noise. Gotta fix that.

EDIT: And I'm running an LC-1

patsmx5

iTrader: (16)

Yeah, I beat you! Get to work Stein, boost is awesome.

You get used to the big turbo and drive it accordingly. It's not laggy above 4k is it? I know that mine wasn't and my turbo was even bigger.

Retard the timing a bit around atmospheric to try and get a little better spool.

Get an automatic, it will make everything better.

iTrader: (16)

Well I don't get full boost till after 4500 right now.... So yeah, kinda laggy. But these are second gear pulls, not 4th and 5th. It does make some boost down low though. Even at 2K I get a couple pounds. It just takes forever to get up to full boost of 10.7 right now.

And yeah, I need an auto bad.

that is so true....not to mention he is not even tuned yet. with good tuning spool will only get better

On a side note, I have been posting alot more then usual lately. Wierd.

Less words and more pictures of your setup.

Nothing scarier than boiling fuel on a hot piece of metal under your hood. I had a bad fuel leak on my old TII RX7. Popped the hood to find a puddle on the intake manifold. Just under it... the turbo down pipe...

So...

Spool still sucks. Here's the timing map I was running before:


And now:


The first one is stupid retarded. The second is what I'd call "conservative", as it still has less total advance that what most here run by 1-4 degrees on average.

I can't say spool improved any yet as I still don't get full boost in second till 4500, but it does pull harder on the new timing map. Like when boost came on in second I was like HOLY ****! But yeah, it definitely liked the timing. I didn't get to rev it out as traffic is terrible. I'll try to get on the highway tonight and do a few boosted pulls and see how it pulls up top now. I don't think I'm gonna try to add any more timing in until I get a knocksensor and KnockSenseMS hooked up and going.

AbeFM

iTrader: (3)

Oh! No knocksense, that explains the map a lot more. :-)

I'll be dead honest, I can't hear knock for ****. I can pull broken pistons and bent rod all day, though. :-P But I see the light, feel the timing pull, and have no idea what happened. Get it and bump the timing for days.

AbeFM

iTrader: (3)

On CA gas, SOMETIMES I'll get knock but not much. I think it depends where I shop. Also, I'm pretty sure there's more timing to be found if I richen things up a bit in the 130 kpa+ range.

Pat, was wondering if you had any issues with the mani. Everything work out ok? I spose I would have heard from you if it hadn't.

patsmx5

iTrader: (16)

Yeah, it's working great. Of course when I bought it it was a T2 FM manifold with damaged/stripped threads. But I knew that. I ended up drilling and retaping the threads, locktiting bolts in them, cutting and grinding them flat, and then redrilling and tapping 3/8-16 holes in a T3 bolt pattern. And then cut a hole in the bottom and added an external wastegate port. I have quite a few hours in that manifold to say the least... But so far, it works perfect.
