Clean car man, still looks odd to me to see such a big turbo breathing through an AFM. I wonder how much is being left on the table by having that there?

Bigturbo,

Let me know what kinda RPM you are hitting full boost with the GT3076R at roughly 20 psi. I am curious as I plan to run a similar turbocharger in the near future and would like to map its performance on my engine. :D Fourth gear pulls would be preferred... :D Thanks for the assistance!

On another note, awesome car!

Hey nice work. What are you running for a rear end? Got any more pics of tranny install.

IIRC... He took the bellhousing from the FD and Miata, cut them in two, and welded to two pieces together to make a single make-shift bellhousing to mate the FD tranny.

Wow that's clean. Show quality clean.

Can you show off how exactly the 8 injectors and how the fuel rails are situated on/in the intake mani?

Just for the story, my cars updates is

New built 1.6 motor
Wiseco pistons,eagle rods,full arp bolts,cometic,acl race bearings, and a new fully port and polish head with my old HKS 264 cams.I pushed the CR at 9,5/1. The old motor that I had 5 years had oil consumption its last days,and one day at 2,1 bar burn a valve at second cyl. Everything was ok but just for mass reasons I built a new motor.
And I sold my JE and PAUTER to a friend and they still works great to his motor.

I also put with reverant an MS2 ecu, running still 8 injectors.

Dyno not avaliable yet, but we expecting about 400-420 at full boost at my 3076.

Or 550 at another reach dyno:giggle:

Dynoed today. Not too shabby.

328hp at 15psi

407hp at 26psi

The MS2 was pulling massive timing as the intercooler was overwhelmed and couldn't cope with the heat on the dyno - hitting 130*F at 15psi and 170*F at 26psi. We reckon we could have made another 30 or so if the timing wasn't retarded as much - about 4-5*.

AF was 11.5-11.8 at 15psi and 11-11.4 at 26psi, mostly due to retarding so much (we were shooting for 11.3-11.5).

Jim, what does a stock Miata do on the same dyno?

Reverant 11-22-2010 06:03 PM

Stock 01-05 w/VVT, 129hp (instead of say, 146hp), on the same dyno.

And for the kicks, a 1.6 on a Garret 2560, 12psi, MS2. 220bhp (NOT whp!), and 200tq, again, NOT wtq.

Jim is this Mass's dyno? Did he cum on the paper cause of his joy or did he cry for the low numbers? :fawk:

Reverant 11-23-2010 04:54 AM

Yes, its Mass' dyno. He liked it.
