How is the idling on the MS vs the Adaptronic?

a lot better. more consistency and it stays within 14.0-14.7 whereas the adaptronic best I could do was mid 12's to low 13's.

I don't really know though if its the unit itself or the fact that there's so much help/support out there and searching for info/answers brings up TONSSSS of threads many of which are useful, and I have a much better understanding of what to tune/adjust/fiddle with to get the results I want. If the adaptronic had this much help/support/info I think I might have been able to dial it in much better too.

Your build is absolutely awesome, pushing the boundaries of what people are so "accustomed" to using and trying.

May I PM you and just get some base ideas/answers on some questions about it?

No.

Actually, there are a few people 9+??? on this forum doing what 18psi is doing- building a motor and going with a medium size turbo instead of a small turbo.

3 years ago and especially 4 years ago, this was definitely pushing the envelope of what turbo miatas do. A few things changed though- I would say the introduction of inexpensive rods and pistons- belfab, supertech, and an inexpensive and community supported ECU- megasquirt allowed for overall build prices to drop by over $1000. Other things like relatively inexpensive and available billet oil pump gears (the stock one dies with too much HP or RPM), and the rise of the china-fueled tuner aftermarket helped as well.

Now 18psi is the wussiest of the lot becauseausagee he has lovely e85 to spew through his motor but he is only at.. 18psi. With a real GT3076 and e85, another miata owner hit 500hp within the past year. Someone needs to get him some dyno time for xmas.

Well I retract my statement partially but I have seen 20-30+ using small frames (just in what I have looked at) vs the 9+ using mid frame turbos, I guess thats why I worded it that way. I am assuming the other guys dont have E85 at their disposal like him?

Not many have the access to e85 that I do. I think there's only a handful of us on this whole board running e85. Not 100% sure but I know its not common.
e85 is AWESOME though

Threw the mbc back on today and dialed it in.

WOW

Look at that pressure rise at 4500




FEELS GOOD MAN
The turbo is just finally (over 15psi) starting to get into the "sweet spot" IMO.

The lean blip at 6200 is taken care of btw lol

I am very happy with the car. Finally the tune is not giving me any problems, the new wga and mbc are getting along, and everything is just as I want it *knock on wood*
For now I'm just going to smooth out the fuel map and get it nice and purdy and enjoy the car the way it is.

Have a few little cosmetic things here and there I want to do, but nothing major.


So here's a question for those here that have seen their fair share of dyno charts and setups and all that jazz:
What power level do you guys think I'm currently at?

The above posted log shows my boost (16.7psi peak), my afr (11.5-11.7 in boost) for those that haven't followed the thread car has a godspeed 3076r and running e85, 3" exhaust.


I've looked around and did a bit of searching, comparing others setup vs pressure level vs timing and fuel maps, and my guess would be either 300 or very close to it.

I know this is ricer bench racer **** and definitely will hit a dyno in the near future.
Just trying to figure out what I should be expecting (or hoping for) when I do.

Of course if results are not satisfactory I'll be buying some additional dyno time to work on the spark map


Anyways, shoot your guesstimates.

I'd say you're still under 300, but it would depend on which dyno you go to.

More than 300 for sure. Bigturbo's 1.6 with the 3076 made 328 at 15psi and very conservative timing. I would say 310-320. That turbo WANTS a lot of boost.

Bigturbo's numbers sound high to me for [email protected] I say over 300- probably around 330, less or more depending on timing? At 17psi your turbo should be pretty efficient. My car is at the same psi now and it is pretty fast when it is not having some stupid problem and sitting there disabled.

I see zero knock retard on your graph and that is great. I say take that 15psi fuel row, multiply it by two, and scale your map up to 30psi and just start turning up the MBC. Timing makes a big difference but if you want to save money, since you are running e85 you have so much less risk than gas cars with twisting the ****, doing a pull, and taking a log.

Interesting.
So I should be expecting anywhere between 280-320 depending on dyno?
That doesnt' sound bad to me at all

If I'm not at 300whp when I dyno it I'll turn it up to 18psi (that is the limit I've set for myself NO MATTER WHAT), and massage some more timing into it.

Well yeah I forgot that 1.6 motors make more power than 1.8s. crank HP? OK then that makes sense.
