Here is what one of our members did:
Sparky weighs 165KG without fuel and 174kg fully fuelled-with 104rwbhp and 74ftlbs of torque.
John (JHP) reckons that when we get the adjustable ECU on her we should be able to get 110-115bhp with a similar increase in torque as she is running well rich at the moment.
The MBP testarossa cylinder heads are the real deal for the older 900 based engines, but the twinspark engines have a much better head as standard since they are based on the testastretta design with a smaller included valve angle, bigger valves and better ports......
great, forum wont accept my images so i'll be back ......
