Tell us a little about you. What cars you are interested, where you are from and why you are interested in learning to tune.
Been watching the hpacademy for quite some time now.Today I completed my registration and hope to learn and solve everything that it's involved with engine tuning.

The head is ported and polished.At this time i have given my cylinder head to my machinery shop because the lifter bosses do contact the camshaft lobes.We went from 8mm lift to 12mm lift.There is still work to do.Alot...We gave extra attention to the engine tolerances from crank because extra revving demands different approach than a standard engine.He is a well known machinist ,friend and i thrust him completelly.
The post is a copy paste from our local forum.The car has undergone many upgrades from the brakes,chassis,transmission etc.It's a track project but it will be daily driven also.The ECU is a Vipec i88.I am still playing with the ECU layout to try sort and figure things out.We will be in touch.Last thing the car will be Rotrex equipped with a C30/74 kit.It's a Kraftwerks kit that i had on the car when it was on completelly stock internals engine and produced 217hp on the crank.After 25000 kms(Not being Intercooled) the cylinder head melted between Cyl1 and Cyl2(during a Track Day session,my bad) so i started this project.I am planning to break the engine in in N/A mode so to see the gains from the theory and afterwards i will add the Rotrex.
