well done Gunni! as always. What kind of fuel are you running?

Gunni, good job bro. your setup is close to my setup except I have top mount.
I noticed you have good torque in between 3500-5500 rpm, my torque at that rpm is lower. Can you share me your tables please?

I've got 637torque and 581 hp on 20 psi.

[gunni]

The torque is this way because I timed the intake advanced and the 56mm compressor.

[VemsedE36]

Gunni, how many degrees you advanced the intake timing?

[gunni]

It was at least 12° crank angle, that and the intake cam on the exhaust side adjusted to regular exhaust timing gives more overlap then just advancing the intake side cam 12°

Are your 1700 cc injectors the ones that can handle MTBE and hot fuel without loosing flow ?

[gunni]

I have not had any problems so far with them, done at least 3000miles so far, short drives and long drives.

[mattias]

Hot fuel may never be a problem with one in-tank fuel pump. Most setups that use these injectors make more power and have more pumps and have a catch/surge tank for the fuel. This is what I've had problems with.

The MTBE problem is a constant one and I haven't really seen it happen over time.

When I have time I'll check the Bosch numbers, there is not much information but around where I live everyone avoids "1700 cc" Bosch fuel injectors.
