Default 12.5 psi 1.6 230rwhp

I finally "finished" my miata. Thank you to all the guys here who have really gone out of their way to help a total stranger. Especially to Brain for doing so much for my MS piggyback. I have owned this car for six and a half years and it is finally bad ***. I have no regrets having to sell my 94 rx7, I might not have gotten this far on the miata.

The dyno is crappy (and not steady state ) but we have used it on a variety of cars and it gives a decent number. It gave my downpipe only 45K mile perfect running extremely well maintained FD rx7 197whp which is probably about 15 less than other similar cars.

I went from the dyno to the 1/8 mile dragstrip and ran a 8.7 with bouncing off the rev limiter in first gear. I am not quite used to the new power. The stock vsld hasn't exploded yet after 8K turbo miles and over a hundred launches at the strip, many with BF drag radials. I am going to drain the fluid again soon and do some chunk checking.

At 12.5 psi: (I was at 208whp at 10psi.)

Post your slip from the 1/8 mile. Nice numbers.

Will do, need to figure out my scanner at work tomorrow. Those damn students need to just leave me alone. Annoying adolescences. Just ask a smart kid.

The turbo was new, $500, and sitting on the shelf. Otherwise, I would have chosen yours for spool.

Tune is very conservative, I insisted because I don't like change. Change of the inside my engine kind.

Conservative? I am running a smaller turbo and making 190whp at 5.5psi. I am still tuned very conservatively as well. The more I see outputs from MS cars, the less I like it.

Or the more dyno plots you see.. you'll wake up and realize they don't read exactly the same.

You sound like FM and how the Hydra can provide a gazillion more HP just by swapping from the Link to it.

The MS is extremely capable... and I'll use it a thousand times before an AEM due to the cost. Just not worth going to such an expensive EMS. (yah yah, go ahead and cry again about the MS fanboys and blah blah this and blah blah that)

Oh, and the car was heat soaked and is running a smooth flowing but quiet 2.25 inch exhaust. (which I thought was a 2.5 inch for a while, but I am still happy with it)

I am unable to scan the timeslip, the software just errors when I push the scan button.

60 ft 1.921
1/8 8.771
mph 77.799

This dragstrip is really low quality. There is an EVO that has a best of 8.9 and an 08 Mustang GT that runs 9.3 with a good launch. But its $5. And its local. I still think my mph should be higher, but I don't power shift.

This is on an American Iron certified dyno, with standard (lowest reading) correction factor.
Stock 1.6l motor.
Running wastegate on the Greddy kit.

I already had it posted up here in it's own thread.

You are right, they don't read the same. Alot of the dynos out there let you fudge the numbers by adjusting conditions to change the calculated hp. Those are the ones that can't get certified for use in the American Iron Series.

I don't have any experience with Hydra, so I'm not gonna bring it in to this discussion.

http://www.google.com/products?q=AEM+30-1710&scoring=p

You can get a AEM EMS for about $1600 shipped. A MS PnP is $720, that's a difference of $880. That doesn't seem like much of a difference when you are talking about building a car. I'm not gonna waste my time trying to argue MS vs AEM, since I can't prove my point without using dyno plots from customers. I don't even know if I could do it that way, since the only direct comparision I have is between the Haltec E11v2 and a MS on 2 basicly identical 280ZX Turbos. I can say that there really is no comparision between them, cause it wasn't even close.

i....never seen a greddy perform so well before. If you said 7-8psi I'd believe you...5.5psi is pretty hard to believe, what boost level was the 146rwhp run at? no boost How did you even run less than 5.5psi without the spool suffering from the wastegate being opened slightly at idle?

Granted I made 170rwhp at 6psi, probably more power ot be had with a better exhaust and spark, but i dunno about another 20.

I dont doubt the car pulled 190rwhp. i just doubt the boost level it happened at. looks like more than one helper spring was used too...doesn't have the dreaded torque drop after 5.2K like every other greddy setup...

The one where I made 146whp was at 7psi the same day we installed the FMIC. That was with all my band-aids and the stock ECU. I remember being told it was running .45BAR, which is actually 6.5psi. I don't have access to the logs, so I'll find out later if that was correct.

No helper springs.

We are actually gonna play with the cam gears and see if we can get 200whp. They haven't been touched yet.
