Don't forget, nitrodann has to run his car upside down on the dyno too!

Agreed, dyno number competitions are silly. I see it all the time with local subaru guys, all using different dynos and claiming their 800whp wrx is the new record, etc. I've learned to go more by 1/4 mile ET or trap speed then by the dyno numbers.

Not that it isn't impressive. It's just silly to make these comparisons unless it is at LEAST on the same dyno.

so long if he used any other dynojet, it would be okay to directly compare.

Fireindc

Unless it's at a drastically different altitude. There are a ton of other factors of course, but it would still be "close" unless high altitude comes into play.

dynojets are pretty universal, alt. ***** everything up, but tit for tat two different dynojets are going to read very close to one another.

who cares. he wont break the record anyway

nitrodann

hahahahaha, I love you 18.

Of course it doesnt prove anything, its a catchy thread title though.
The goal is quickest mx5 in the country with number plates (hopefully outright). Would you guys even click the thread if it said "Australias quickest mx5 attempt". We have a population 7% of america, who cares haha.

This car has done a few 1000m runway drag events and will do more, we will try to get it to the strip also.

Do trap speeds count if the car is babied off the line (within reason).

I'm not trying to poop on your thread and I think the work you've done is outstanding. The fabrication is beautiful.

You keep bringing up the fact that this car made 297whp on a shitty log manifold with a 2" dp, etc. etc. Seems like that number might be a little high, that is all.

Keep up the good work, and I'm curious to see the results after you switch to EFR

Trap speeds count, but not in a competition for "quickest." That's what ETs are for.

18psi

iTrader: (76)

Yup, trap speed will not lie: If this car hits even 350whp but traps 115 or less we will all know what it REALLY made. (under 300)

cannot wait for results

nitrodann

what does it need to trap to prove it making over 300?

It trapped a kilometre at 235 on a slippery surface (gravel on top) previously.

115-120MPH is about right for a miata in the 300whp neighborhood
Someone correct me if I'm wrong.

nitrodann

Here is the exhaust.

It has 2 braces and a V band.

Its tucked as high as I could get it, a flat floor and diffuser will fit with ease and clearance.









It also has an extra piece of SS rod on each of the hangers to make sure it never moves.

I would think anything under 115 and you don't have much of an argument that a miata is making 300hp. 115-120 is a good range to expect.

18psi

iTrader: (76)

I like that exhaust. Good job.

Except for that tab to the transmission. It will rip off after a while. Ask me how I know.

What you should do is a ring/band/whatever you call it around the pipe, attached to a bracket. Kinda like soviet did. Kinda like FM (I think) does.

Otherwise nice exhaust

nitrodann

I'll take a better photo of that bracket today. Thanks.

Dann

iTrader: (25)

Yeah, a welded bracket like that has been known to rip a section of the exhaust pipe out. Do something more like this:

Flyin' Miata : Turbochargers : Parts and upgrades : 1990-97 2.5" FM exhaust brace

another vote for doing it the way 18psi suggests. Nice looking so far!

EDIT: That is, if you feel you must run a bracket there. I haven't since my GReddy kit 10 years ago.
