not winding me up - just providing facts.

that is the book weight of mine - the weight with me and petrol in it is a lot different.

Where is that 1600 kgs from Ian?

Book figure is 1530KGS, mine will be about 1600KGS plus occupants plus fuel.

The two cars are very similar in weight, yours is quite heavy for its size, im shocked!

Which is a hell of a lot for someone like you Ian.

It does seem to hold marginally more boost higher up the rev range and spool a fraction of a fraction quicker. Not a lot in it yet but more changes to the maps and there may be a benefit after all with this turbo.

further analysis/logging and tweaking the wgdc has given a top end gain. Maybe worth it after all.

Instead of dipping down to 2.8 load at 6000 rpm it will now consistently hit 2.95+ load at that point. Quite nice 8)

hehehe

Just loaded what I think is the final piece on this and the results are pretty impressive. Will collate some dyno graphs and post on in a bit.

was (on normal fuel)

3rd gear:
30 - 50 mph = 2.1 seconds
40 - 60 mph = 1.9 seconds
50 - 70 mph = 2.0 seconds
60 - 80 mph = 2.5 seconds

now (which is actually almost the same as the methanol testing)

3rd gear:
30 - 50 mph = 2.1 seconds
40 - 60 mph = 1.8 seconds
50 - 70 mph = 1.8 seconds
60 - 80 mph = 2.1 seconds

Runs done in 3rd gear, all on the same piece of road.

Yellow line = as it was with 1/4 tank of Tesco 99 (14C ambient)
Blue & Red lines = position now with the Prodrive Boost Control Solenoid (9C ambient)

No difference on spool up but it definitely holds boost better and as such the gains in bhp are pretty huge

nb: these are wheel figures
