Surrey Rolling Road Day - 27th March
Surrey Rolling Road Day - 27th March
Weighbridge address is:
Day Aggregates
Guildford Road
Woking
Surrey
GU22 7QE
It's £10 per printed weight receipt.
Have got some weighbridge info now. I've found a place in Woking which is nearer than the one Stevie and myself were originally looking at. It's open 9am - 11am and as I have to be at the rolling road at 10am with everyones deposits I'm proposing to go to the weighbridge for 9am. Of course there is nothing to stop other people making their own way there and meeting us at the rolling road later :thumbup1:

A good turnout and a nice variety of cars (not just MR2s even though most were from IMOC). Thanks for organising it toxo !
I didn't run because I still don't have my own car back yet. edeath and toxo did though, but I'll leave them to report on how they got on.
I took a load of pics. My mis-behaving camera seems to be getting worse and I really need a new one, but hopefully I still have some that aren't too bad that I can post up shortly.

Car weighed 1410kg with me in it, so for arguments sake minus me and the 2 subwoofers 1310kg.
MR2 Rev2 Turbo ECU, at flywheel:
275bhp at 5800rpm
280ft/lb at 4800rpm
231 at the wheels
ST205 ECU, at flywheel:
283.7bhp at 5800rpm
277ft/lb at 4800rpm
240 at the wheels
All done at stock boost (0.96 bar)
Pretty pleased with that. It means I get around 16% transmission loss and my power to weight ratio with the GT4 ECU is more or less 210bhp per ton at the fly. Also had a comment from Charlie that the GT4 ECU was much better at fuelling - the MR2 one was dangerously lean when coming on boost. That would explain why the GT4 one feels smoother in its power delivery.
God I love maths.
Just done some messy sums:

.186.2 Bhp at Fly
154.8 Bhp at Wheels
Was Supercharged Racing Green IS200 Sport. Now APR Stage 1 Seat Leon Cupra (220 Bhp).
Well I dyno'd at 186.2BHP so means I have somehow lost over 10BHP (Was 197.8) by fitting the Katana manifold. This has put me back to where I was before SPC sorted out my fuelling problems as that is what is causing my power loss. Running pretty lean as it's running 13:1 at top end but has lost torque across the rev range. So I'm pretty annoyed as it's cost me loads to lose 10bhp .

I've got my own dyno graph in front of me from my own (stock) run there a while back, and my fuelling is 13.1 at 4750rpm, but then a bit more fuel kicks in past then to take it to around 12.7-12.8 towards peak power (at the time Charlie from SRR thought the fuelling looked "spot on"). Though of course you have the charger and FCD.

13-02-2017, 10:25 PM #30It was a real bummer that you seem to have lost some power Ed. You weren't alone though, some people who ran were delighted with the figures, getting a bit more than they expected, but conversely some were also scratching their heads afterwards, trying to figure out where the power had gone.
