(ENGINE) 12A (Extend) Streetport Dyno result.
 
Hi guys, I got this done in Late april. I only posted it in the ms-efi forum, thought some people here might like to see it too.

I'm pretty happy with that result.

114.7rwhp = 86rwkw

Out of interest, that rise in the power around 134kph was well off the 8000rpm racho. Just for note the run was done in 3rd gear

Was running 28BTDC timing with 0 split after 5000rpm

The motor is a fresh rebuild ~7000kms

Mods done are

85 12A rotors clearanced
New 82 Housings exhaust ported
3 window rear stationary gear
82 N "Grey" Tallport plates, extend (street) ported
New bearings, seals and springs throughout

Tuned Nikki carby (running 12.8:1 under load as graph shows)
Megasquirt Controlling ignition Coil/plug

The exhaust is a race style header that collects about the gearbox into 2.5" piping. 2 1.5ft hotdogs, and then a stupid centre offset muffler under the bum. The over the diff section is press bent which I'm looking at changing soon

Lightweight Flywheel
Daiken HD clutch
4.44s in differential
Jspec 12AT gearbox

nice to see more numbers from the 12a, you should be able to squeeze more out of that though. If its a SP ... this is mine:
