After 1100km....

Currently done about 1100km and engine is feeling looser....torque is very good at mid range, esp 3500 rpm onwards. Noise on full throttle is also quite menacing, but still needs a lot of tuning and setting up. Need to calibrate my knock sensor properly and activate the water injection. Water injection mapping will also take a lot of time, sigh, SP will need to have some proper work out session on dyno soon. Planning to get the ECU to activate the water injection based on 3D mapping ( load, tps and rpm input ) and to further fine tune max and min flow rate using the water injection controller fitted in the dash. Also need to fiddle around with the water/methanol ratio and may consider AV Gas for track days to reduce any chances of pre ignition (knock) and also to boost on the power figures. Lets see how it goes. Anyway heres some pictures of SP in its current state.

SP is back home!

Collected SP on Saturday from GT and to date have clocked about 450km, heck even took it to work today. Car feels good, accelerates well, and have the rev limiter set at about 5k rpm. Car behaves and drives very well, even at low rpms, totally different to the previous setup I had. On the dyno car made about 18kg of torque and 141 whp at 5k rpm with 14month old fuel and old plugs. This was obtained when we were doing the initial tuning for running in the car. Water injection also not activated, so its looking good, and I look forward to hit the 1000 km mark before we progress further. Pictures hopefully on the next update.
