Meet the Little Enchilada.

[miatamanone]

Keith    Has anyone documented a 0 to 60 time and quarter mile time with Little Enchilada Installed on an MSM? I love numbers.

[cDc_Geo]

My guess is that it would be something similar to this:

In my opinion, there are just too many factors to get straight results.

Nobody has documented it as far as I know.

Did you know that the big three car magazines don't calculate 0-60 the same way? C&D and R&T subtract approx. 0.3 seconds for rollout - basically, they ignore the first foot. Automobile doesn't. So, the same car, tested by the same driver, on the same day, etc, etc would give different numbers depending on which magazine is publishing the test.

So yeah, it's a hard one to duplicate with any real accuracy.

A good article by Dan Edmunds (a Miata racer, he's one of us) about this sort of thing: http://www.insideline.com/features/how-we-test-cars-and-trucks.html

Thanks Keith for the link to the article on 0-60 timing of cars.

Flyin Miata is the only aftermarket company I deal with and I have 3 Miatas. All parts are superb.

Keep up the great Research and Development Work. It is your lifeblood.

I use a GTimer, which I realize isn't Perfect, but I did run 0-60 and quarter mile times before and after LE installation. I used the exact same road for the times, but runs before LE were done on a 70 degree day, whereas times after LE were run on an 85 degree day. I also probably came out of the hole a little harder with the first times. I have gotten where I don't particularly enjoy abusing my car.

Before LE install:
0-60=5.92 sec.
1/4 mile=14.62@93 mph

After LE instal:
0-60=5.55 sec.
1/4 mile=14.30 sec.@93mph

I really think that if I had made a few more runs with the LE as I did before the LE, that I could probably shave a couple of tenths off the times. A cold day might produce some really great times.
In all, I am very satisfied with performance with the Little Enchilada. Throttle response is so much better. I am not into drag racing anyway.

Any idea of how loud this kit makes the MSM? Track has 90dB limit. There are work arounds but just wondering.

[SilverMiataRacer]

Wow, 90???  Really???  That's pretty quiet.  The exhaust isn't too loud but I'm not sure it will pass 90.  Where do they measure and how??

Our track has a stationary meter about 30' off the edge of the track about 2/3's of the way down the straight.  Joe and I never had any issues on DB but our limit is much higher at 103.

I run at Laguna Seca with my full FM exhaust without issue. I think the limit was 91 or 92 my last time out but you should be okay.

I'm assuming he is speaking about Laguna Seca. Thanks to the rich neighbors and the growth of Monterey toward the track, the sound is limited to 90dB for most private track days. Sound is measured on the run out of turn 5.

[SilverMiataRacer]

One of the "tricks" used at our track is to use a turn down pipe on the exhaust tip and aim the sound away from the meter.  Even though this seems like cheating in reality it's not since the meter is on the outboard side of the track and so are the people affected by the sound.  If the sound is aimed inboard you are bothering them less too.

[Laguna1]

Cool thanks Magnus, info I needed! From my understanding it cost $$ to go above 90dB

Copy that SilverMiataRacer, is the work around I was speaking of.

[millsj]

Or make the sound meter a "shift" point.

Here is the calculator I use for 0-60 times. Saves wear and tear, tickets and other things.

I would be interested to hear from Keith what the flywheel hp is on a LE. That is the number to put in first. Weight = 2500, RWD, Manual.

[twobone]

I made the decision to keep the rear muffler and get the FM downpipe for the exhaust part of the MSM upgrade.  I still get the wonderful boost sounds but without worrying about exhaust noise.  It makes my car a bit a Q-ship  

From what I've read I probably didnt give up any measurable HP as the major gains are from the DP.

We have never done any flywheel testing. A conservative estimate would be around 225 at the flywheel based on the change in wheel hp and Mazda's rating. Those who are looking to inflate their claims will come up with a higher number by using percentages of drivetrain loss.

Twobone, you will have given up measurable hp, probably mostly at lower RPM as the turbo works to overcome that greater restriction. But you're right, the downpipe has a bigger effect.
