It was one of those portable dyno and it was outside hood was also down. I'm not sure why its in MPH not RPM


Next mods are gonna be Exhintake cam and MS2.
yes yes one day I'll go turbo!

seems a bit low... 120hp? Thats practically stock, I wonder why. plus mph? wtf is that.

You'll never see "stock" power from a stock engine. 1.6s supposedly have 116hp, you have an INCREDIBLY healthy motor if you get anywhere above 100hp. Which begs the question of why SM 1.6 motors can have 120 hp.

^sure I get it, but I am saying I have seen bone stock motors dyno that. I guess I could look for a dyno to compare, but I am not sure it matters since dynos aren't so easily compared. different day, different temp, humidity, hell even different settings on the dyno.

why the ---- did yours not come with a tq graph? You can't tell ----. This is like the ---- who came into the MS3 forum and posted a dyno that w/ tq and hp intersecting at 5500+ rpms. We had to tell him to go back to the shop and get them to change their silly settings. wtf?

Needs tuning.

When throwing a CEL on an NB your AFRs are likely in the 11s. There will be gains from leaning it out to 13.0-13.5 and giving it some timing.

Also, I wouldnt bother with the exh-intake cam trick.
A mild cam regrind will be way better. I suggest contacting Delta to see if they offer a BP cam grind (I bet they do).

Then, perhaps Honda intake manifold?

After going through a lot of this http://forum.miata.net/vb/archive/index.php/f-73.html 120hp is a good number.

It was a dyno at a car show for $40. The first run was in 3rd gear then the rest were in 4th. I didn't notice until I got home that it was in MPH. I'll get a hold of them.

I want the exhintake cam because its very cheap and I was impressed with doing it on my brothers 97. I think I'm gonna cut my manifold and my MAF screen. I hope that puts me closer to 130hp. Though I don't think I will break 130 without some tuning.

You can pick up a msm cam from mazdaspeed motorsports for $90. no cutting, no issues.

You can look at my cold air intake if you want to get those 2 ponies from the intake.

It is in MPH when they don't have a tach sensor to put on your #1 plug wire. Many dynos are set up that way, especially if you are at an event where they are cramming people in and out like a dyno day. It's just the lazy way of doing it.

As for the numbers that is a pretty reasonable one. Wheel horsepower will aways be much lower than rated engine horsepower in your car brochure because of the drag of the trans, diff, wheel bearings, tire sidewall flex, accessories, etc, etc. A 1.6 with miles on it will often make 90-95 whp and a 94-97 1.8 will make 100-105 whp stock. That's just what they do. Hitting 120whp is pretty reasonable with his setup. The dyno can be fooled to read a little higher with lighter wheels and a lightweight flywheel because the dyno itself will spool slightly faster.

You ready to install some new rings in the mazda?
 
So here is a video can someone give me an idea what happened at :23
http://www.facebook.com/video/video....29524740488476
the shop where the dyno was said I need new rings.

At the time I might have added to much oil due to the location not having any flat land.
