Beta VX engine tuning!
Posted: September 8th, 2009, 9:07 pm
My X1/9 Dallara replica project has now come to engine fitting and i am done making space for the VX engine and gearbox,i am fitting the last custom engine mounts this week.
That means that i am very close to start stripping down the engine and rebuilding it with some power increase, i am fitting it with custom electronic fuel injection and ignition control with a coil for each cylinder thats mostly decided.
All GC preparations of the cylinder block and head will be done to have a strong base, the lubrication will be kept in shape wit a dry-sump system.
I am thinking of raising the boost pressure 1-2 psi, what i need some help deciding is what compression ratio i should go for i am thinking of increasing it to 8:1 but i need some input from some with experience on VX tuning.
Is it possible to get performance pistons that are around 8:1 CR and maybe 85 mm bore, is there any possibility to get hold of the new type three layer thin head gaskets that you can get to a lot of engines now for the TC engines or is it only the standard and reinforced old type that is still available.
Putting fuel injectors at the inlet manifold should make a much happier engine than the originally carb system fitted, does the VX supercharger need fuel running trough it for lubrication if it does i'll probably just use a set of injectors before the VX also.
