Stroker build dyno result

Had the car back for few weeks now but haven't really had a chance to properly drive it yet. However, it went back to Race Torque today for a re-tune after I found the metal cat had melted and collapsed inside. The guys fixed the problem for me and re-tuned it yielding 227kw and 440Nm @approx 1.2bar in 40 degree heat.
So a nice round figure of 300hp with lowish boost, more importantly plenty of torque where it counts, quite happy with the result, now let's see if this translates to better times on the track.

Few typos on the printout with my name and should read 2.3 as capacity

2.3L Stroker build

RaceTorque is currently rebuilding the engine with a Manley 2.3L stroker kit. Took photos of bits and pieces before it all got assembled.

Machined block. Had to bore out slightly larger than anticipated as the bore didn't come out clean. Sounds like previous builder didn't clean them up properly after some detonation damage.

HKS 274/278 CAMS are in as part of the build

So my 1st ever sprinting season is over. Managed 9th outright and 5th in 4WD Open class. Also managed to get into 55secs at Barbagallo short track. Quite satisfied with the result considering I'm still on a steep learning curve. The Evo has been amazing all season so I'm rewarding it with a fresh stroker build for next year. It's previous forged build did start to show signs of wear anyway.
