[Cochyn]

Brill Dave, must be a fun handful

[SHaDoWLanDZ]

Great spec. Nice work Mark (and Dave)

How are you making so much torque down low with such a large turbo?!? That's awesome...!

[Sunnysidebb]

Esso 97

I think we all missed the Gasp.......97 ron fuel is where its at these days. You cant get 99 everywhere especially in Scotland. Hopefully Mark will have some figures for 95 on my engine some time soon.
Its this development with fuel in mind that's really ground cutting stuff. I cant wait.

Engine spec boost and our fuel even though it's 97 must be good. And the guy behind the key board has done a few cars lol.

Selling yourself short, a lot more than just keyboard though isn't it Mark?

Mixture prep, fast burn, mach numbers, lengths and timings?

[cossiedavid]

Mark knows his stuff and he knows it

Yeah I'm not that fortunate to have someone of Mark's talents and expertise with these cars here in the states. My tuner is considered one of the best but has never tuned a YB before mine.

[Fizziani]

Get it done by mark when he goes over for his annual drink up at Sema/las vegas

haha

I do fly abroad for mapping cars.
A yb is no diff than most 4cyl turbo engines of its type.
