Guys

As mentioned before I have had a trying time with the S3 from Begi which involved lots of problems. We can discuss that later.

The car is currently in the hands of Ken Hill (Flying Miata fame) at Oracle Tuning near Reading PA.
For those of you who don't know, Ken is an electrical engineer and Miata enthuziast who spent 5 years at FM as electronics/tuning specialist.
He is also a really nice guy. When I brought him the car I spent over an hour talking and looking at his car. Very nice visit.
I also had the pleasure of taking him for a speed run in my buddy's 03 SVT Cobra running 19psi. He liked it.

I cannot say enough good things about Ken.

 

A true gentleman!

 

Good numbers. I live near Reading...where is Oracle Tuning?
Are you from the area?

 

I just realized you still have a stock MAF and IAT sensor...then I saw Xede. Wow, those are great numbers!

 

I'd like to see the spark table if you wouldn't mind

 

From the Xede? sure when I get it from Ken.

Too much power for injectors that sizs

 

I live in Yardley Bucks Co.

Yeah, my numbers are scary. I seem to need a stoker kit with hardened rods etc before even racing it

 

What do you mean?

 

The boost gauge is so cool.
He put in an led idiot light to replace the idiot light shaped like a gauge. Thanks Mazda.

I guess I had better think twice about leaving it at 12psi.
The lower curve was at 10psi by the way.

 

I am just shocked to see that much power on 12 psi on just a 2560. That is sooo impressive. Stock msm exhaust? What is diameter? Anyother trick aside from xede and 2560??

 

Yeah, isn't it cool?

All mods were listed in my post.
Expanation: Ken Hill is a genius.

I have the DP but stock catback. BTW with just the DP it has a very very nice growl. No drone or buzz.

Unless the injectors are serioisly underrated, they are too small for that much HP.

 

Dyno jet don't lie.

 

They're 450's Min...supposedly rx8 425's are good for 260-280 at 60lbs fuel pressure...
What is the most anybody ever dyno'd with rx7 460's?

 

I know the fuel pressure thing seems iffy, then again so does that much hp on 12lbs with a gt2560 pulling through a MAF...
I'm not calling BS, but something just really seems odd...
Perhaps MSM head/ cams are that much better at making power than older 1.8's?

 

Assuming a BSFC of .65 and 270HP, the estimated fuel demand comes out to around 43-44 lb/hr of fuel per injector which is roughly 450cc/min. They are most definitely maxxed out at that power, but workable. If we got a log of the duty cycle we could know for sure.

Of course if it overboosted, the ECU will not be able to compensate with more fuel and it will go lean quick.

Awesome numbers.

 

Nice. Very nice.

You can pull the xede tables yourself. Install xmap off the Begi cd (or grab it from Chiptorque), connect to the serial port, and turn the key on. Download maps. Show all maps. Screenshot for win. We want to see the MAF and the Timing table. And the TPS table if it's used, this is an MSM right?

 

Yeah 270hp at the crank.

Crank.

Look OP, I am not being a hater. Your car is obviously fast and probably drives fantastically. I am just talking about the numbers, not the tuning job or your setup.
