Congratulations on your purchases. I actually thought you were just another big dreamer when you started posting here.

As for the tuning, I can understand just going with the base map that you will get from FM while running the stock engine. As long as you tell them your situation Jeremy will provide you with a good starting point and you will only need to tune fuel. As long as you are able to keep the boost levels under control and not push it you will be fine. I was in the same situation with my car awhile back and ran a tune I got from FM for quite a while without any problems on my car.

When you do get the built motor, please be smart enough to have it tuned by someone that knows what they are doing.

 

Jay, Hustler, point taken about the tuning. My reluctance for getting somone to do it for me stems from my experience with anyone ever working on my cars for what ever the reason. I get the car back and find that it has been half assed together, I'm pissed that I even let them touch it. (My job in the Army is to look for fucked up work on helicopters, point it out and make them fix it) Over the years I have only had my car serviced by a "professional" a few times, I do all my own work unless I am deployed. So when the subject comes up my first reaction is to do it myself.

If I found someone that is well known for his abilities and I can see a few cars that has been done then I don't have a problem paying for a tune.

 

Greg,
Scott Siegel at Topspeed in Alpharetta is a well respected Hydra tuner. He's popular with the Suby crowd. Call them up and get a quote. A Hydra is a Hydra. Should be easier on a Miata truthfully. I'm sure he's tuned quite a few Suby 3071s.

Not sure if they tune Hydra, but Stage6 in Jacksonville has turned out some seriously mean cars and they aren't too far from Savannah. Welcome to Stage 6 Motorsports - Automotive Performance

Sounds like the car is going to be sick.

 

Umm.. No. That is a false statement.

16psi is 16psi. 12psi is 12psi.

 

I agree that you should be ultra-carefull on selecting a tuner. I think you should ask them how they're going to tune it, and to define what they call safe. I couldn't really find anyone I liked to do my car, so I did everything I could to educate myself and I took the leap of faith.

Not tuning the car is foolish. First you'll enjoy the power, then you'll appreciate the drivability more than the rubber laying qualities.

I live out of a suitcase and although I don't have too many bullets coming at me with my job, I know what its like to do this stuff when you have very little time. I'd fly home, kiss the wife and kids, then drive the car to Colorado and have it tuned by FM.

Why not do this in September, then drive back and do "miatas at hallett?" You should have the best equipped car there, and I'd love to rape it for you. You'd have a ton of fun out there and if you've never been on the track, I'll try to help you not kill yourself.

 

oh yeah, nothing like the confounding variable game. I'm all booked up this morning with e-thugging, but if I have time later I'll jack with your bullshit.

 

You fail at understanding turbo efficiency and the ideal gas law.

 

No worries, I got this one. You can take the afternoon shift.

 

I knew I should have written a lot more for that post and shouldn't have been so brief. I apologize for that. The way I left it was certainly not 100% right and I will agree with you on that.

Let me preface this by saying I have NOT looked at the maps for these turbos.

That being said, the more efficient a turbo is in a given pressure area, the less heat it makes right? i.e. compare two turbos at the same pressure ratio, the more efficient one will produce less heat.

So, the bigger turbo, which is producing less boost, should be making less heat than the smaller turbo making more boost. This is totally based upon a blind assumption that the bigger turbo will be about the same efficiency in that pressure ratio as the smaller one.

 

hakuna matatta.

 

This should be fun.

Bah, nevermind. I'll just keep my mouth shut. You guys are used to dealing with 12-16psi, which I'm just learning. I've been used to 25-40psi with DSMs.

I just picked up a 99 miata which I'm planning on putting an FM Hydra kit onto, but that's where it'll end.

 

Well, you have a point because you could have identical pressure ratio efficiency points if the target pressure ratio is remarkably inneficient. So yeah, I suppose I could have the same efficiency at extremely high pressure on a 2554 and extremely low pressure on a gt40r or something.

 

I think that's what I was kinda getting at, however, I did a horrible job at conveying that message.

 

well, maybe when you learn how to "convey messages" you can "see a naked chick" for the first time in your life, virgin.

 

Ahh, I love the maturity level. Should we start with the mother jokes now?
