My RA1 are 245's and i thought they would stick with anything pretty much, but man i was wrong. i am about to throw in my 750cc injectors and crank this bitch up. I figure it will drive the same as it does now and have enough room to beat that C6 Z06 in my neighborhood that the guy keeps laughing at my "cute little 4 banger".

he has a walbro 255 upgraded fuel pump in the car. this man has been working on his turbo miata for over a year. when i first met him he was stock now he has all the right parts to make good power. i helped him most of the time including the 6 speed swap and other fun turbo stuff. i would agree maybe he needs bigger injectors and a new intake manifold to make more power even an external wastegate would help but on 91 pump gas he made great power...

I another person who would love to see the maps Shawn came up with for your setup. As they will never be plug and play for any bodies setup but yours... its more of a reference from a well known quality tuner.

Post up the maps puhleaze.

Yea, cast mani.

Hey Nick, if you can please post up my maps for me...i do not know how to post it up..LOL! if anyone wants my ms files hit me up with an email...i send them to you.

thanks tony.... its because of you...you got me addicted to boost!!!!!:crx:

I use to have this crappy white miata with red rims before I met this guy..:giggle:

I'd like to see them :). Didn't see an email link included in your profile.

splitime@gmail.com is mine :)

email sent

Want me to post them up here for you?

please!

Here you go :)

Why did your dyno operator input 5.10 as your final gear ratio? If you have the 6-speed and the 3.90/3.91 rear gear your available ratios are "14.7:1 8.87:1 6.43:1 4.91:1 3.91:1 3.30:1." A 5.10 doesn't make the list.

That will render the data useless and inaccurate, except for tuning from one run to the next for the net changes.

You could be making more or less power than the chart says depending on what gear the operator was in during the pulls.

That sucks. I hate people who don't follow procedure when that's what you pay them for.

Maybe you can get him to redo it correctly.

That might explain the high torque # in relation to hp.

This seems like a good chance for me to be educated. If you are measuring torque and hp at the wheel and plotting whp and wtq what does it matter what gear ratio you are assuming?
(I am still relatively new to all this so please point out what I am missing here. It seems like he is directly measuring the figure of merit he is plotting, namely performance at the wheel, does the gear ratio play a role?)

The Dynapack measures torque and calculates acceleration, I believe (unlike an inertia Dynojet, which measure horsepower and calculates torque). The torque measured at the wheel is a huge number, since there's a 4.10:1 reduction at the rear end. You divide the wheel torque measured by the rear end ratio (and dyno in the 1:1 gear) to get the torque measured at the end of the driveshaft. If the 5.10 number was used, his numbers would actually be artificially low.

wow, we got some smart people here...good thing i posted this thing up...so what am i really pushing in hp?

I had assumed that they were just measuring/plotting hub torque and using the hub rpm to get wHP (and plotting it against engine RPM). I gotta do some reading.

It could be done that way. The hub RPM would be lower than expected, which would make the power numbers low. I wish they would plot the damn torque and HP curves on the same chart.

fucking afr graph, please.
