yeh absolutly I was thinking high 3's before I picked the car up but it does feel like im in the 4's as the car is in a completly different power band.

Anyway thats what dyno's are for really so I should get it booked soon I think.

Sorry clan this is well out of my depth that kind of stuff, how would you reduce / change a compression ratio? if its engine work maybe its something I could think about later on when fine tuning.

Special Pistons with a dish in the top but it all has to be calculated to suit the engine bore and stroke and cylinder head and boost pressure you are dealing with .. This is something you do at the beginning of the process rather than the end otherwise you will have to remap it all again ... ( Or/and burn valves and holes in pistons ! )

ah yeh I see now, just had a quick look at where I got my rods and pistons from

I think the compression ration was 8.5:1, but they did mention a whole load of engine stuff at me an I glazed over a bit.

the best I know off for you want is Gartrac. its near to you. I used them plenty of times when used to race mk2 escorts and 3.2 capris in the 90s.

thanks for that, its ok I already have the car remapped now so all good. Im not sure they would touch the volvo software either though.

Get it down to Regal Autosport in Southampton, they have a rolling road and are a nice bunch of chaps.

Plus there is lots of eye candy, I work near by and quite often see Aventadors, Huracans, R8's etc driving by from there

yeh just had a look at the website, looks like a nice garage but their dyno time is £95 a session. Ive seen a few here for around £70 a session. Just looking around to see if any car clubs etc are running rolling road days as you usually get a good deal there.
