Well for those not on .ORG who dont lurk in the diesel section i am proud to annouce that the car project has been completed....



I guess the first this to explain from the thumnail are the different runs...

teh green run was how the car was running on the MAFless map designed to reign in the wingy injectors - but with just the hybrid ones fitted.

that return a respectable 211lbsft torque and 147bhp without a single hint of smoke even on the dyno - if you consider i was only getting 22lbs-ft & 160bhp with the wingy injectors high EGT's and smoke screen i was suprised and quite impressed!

Next Matt got working his magic and we discovered that there is an additional limiter in the mapping side when switching to a MAFLess remap. Not an Issue with SDI's as they flow enough fuel to not hit this new found limiter.

So we plugged the MAF back in and got the red run..... And all i can say is result

267lbsft and 169 bhp....tho a few drops in the curves that matt wanted to smooth out, as well as we detected i was only running 23PSI of boost.

so we uppped the boost to around 24-25PSI (not 100% sure as not using a boost guage and the MAP sensor can't read above 23.5PSI) and did the final run....

end result 170bhp and 269lbs-ft - the blue on in the pic

EGT's were peaking at around 850C at 4400 so well within safe limits, and on the road there is next to no smoke - a bit of a haze but nothing worse than a particualte filter burn off from the modern cars!

So all in all i failed to create my MGSZ 180TD - but i got dammed close. Initial run up the drap strip next to matts serious impressed me, as did the quick blast from the traffic lights on the way to the cash machine.... had serious wheel spin in 1st even with the ATB, but dropped it to second floored it and quickly ran out of revs - even with it having a torque limiter!

What i find really impressive is that even at 4000 rpm i am still getting 220lbs-ft torque - which is more than you get out a standard car with a remap at peak levels!

the long schlep home was not great due to the weather, but it was still nice fun - just rying to find an excuse to take it out for a proper run now the weather is nice today

Is funny i did say that i was finished with the car, but I have just been able to get my hands on the stainless mid section by wingy to complete the whole exhuast and at a bargain price too as it is 2nd hand
