After reading about a potential issue following a rolling road tune, I thought id ask this as I am going to SRE this Friday - I trust that Neil will do a very good intelligent tune.

With that CR and cam I'd say running 24 deg advance on boost will be safe. Not sure what boost you are looking at but 15psi will be fine.

We stuck 25psi+ into the van's engine on 8:1. It took it all day long. Gasket, bores and pistons where perfect when we took it apart. On 11th Feb, 2015 robert said:

The 173 was achieved on 17psi. Fuck knows what it was doing on 25psi apart ruining my underwear on the way to MITP. If something is worth doing, it's worth doing half of. |

25 psi is a bit scary on the road, but good fun on the strip... On 11th Feb, 2015 robert said:

Hahaha!! Well it's interesting at 10psi - rather a lot of torque steer, can't imagine what 25 would be like! Fun though I'm guessing!

We had a valve on the bleed line. Wheel mounted switch flicked between 7psi and 25... We needed that to get it of the line without masses of wheel spin. On 11th Feb, 2015 robert said:

With it set up well on 8:1 20-22psi is fine, iirc nick on here runs around that boost on 8.7:1 Audi s4 b5 - 470bhp & 486ft lbs

Yep. My next engine will be higher compression. Something around the 8.7:1 marker. If something is worth doing, it's worth doing half of. |

Yeah i'm running 20psi on 8.7:1, my advance is 22 degree's across every slot when on boost. I did bump it up and down a bit when on the rollers before but it didn't make any difference so have just left it as is. On 20th Oct, 2015 Tom Fenton said:
