Won't be back there now anyway. Just need to find someone reputable in chester area now.


Have to wait to get home now before I can do more, not sure if I should check compression as well?

start with the easiest, simplest and most logical.

verify the dyno results first.

blink motorsport are up that way, they have had 2 similar spec cars on their hub dyno so you have comparitive results, around 172-4 at the hubs.

The graph won't cross in the rihht place as the scales on torque and power aren't the same

And no it won't be correct on std timing marks.

well spotted.

certainly not, and it will still be off on pipers figures, but timed up as standard wouldn't produce a torque curve like that, so I'd go back to vis motors as first check.

Which begs the question, what is the correct way to time the pipers for optimal performance? Mine are just on factory pulleys timed using the proper tools.

I can imagine with the engine in the car that the rear bank will be difficult to time like this!

I'll check the vis motors as soon as I can, not sure when it will be though :/

Or I could just stick some fresh ones in and be done with it and repair mine as a spare set.

Timing wise I'll be best getting it done soon and I can then see if I can get it done maybe at the blink place

Hopefully it's an easy job to get me running spot on!
I guess I'll then see a noticable improvement in performance if it can all be rectified!

How do these results stack up against staccatos (mine) dyno. Don't the cars share similar mods?

a typical torque shape, the vis at 3k & 4k clearly visible and the way the torque tails off. the usual gulps at vis opening in the afr too!
