Keefo, Catterall1 and myself attended a RR day on Saturday. This is the results from my 1.6 ZR, so i'll let the pictures do the talking, but i'd just like to publicly say thanks to AA Autosport and ZandF Tuning for the work they've done on the car.
Touching 150 at the fly, nice - Still only slightly more powerful than standard though
Power curve is nice too. Torque curve does look odd though, I would guess that's down to it running a custom map?
1.8.sammyp, which size engine did you have? A 1.4 or 1.8?
Well to be honest, the gears have never been the best since i originally bought the car. I have the usual trouble getting the car into 1st and reverse, but they are pretty shocking throughout. Have to give it quite a bit of revs from a standing start to get away smoothly, so i'm wondering could it be the gearbox that is causing the loss?Thats very odd how its "lost" that much power through transmission losses imo. When I had my old 1.4 16v engine on the dyno it was 103bhp ATW with minimal transmission losses and that was using the same R65 gearbox as you have fitted to your ZR. I belive your ATW figure is accurate but after seeeing 127bhp from Pandy's 1.6 metro with similar cams fitted I would be more inclined to say you had ~130ish ATF rather than nearly 150bhp.
Otherwise, good result and hopefully next meet you can show it off to everyone![]()
lol unfortunately i rent my property, and struggle to get through the month as it is without having a loan on top of all the other billsGet yourself a loan / Remortgage the house Wallsy and buy a Quaife SCCR box. Bye bye power loss through transmission, hello awesome sound and being able to bang it through the gears without a clutch
Trust me, once you've driven a car with a straight-cut box you'll be addicted to the noise and how you can quite literally lift off and "bang" it straight into gear!
I'm not good enough with Transmission to answer that! I can just about with a lot of struggling rebuild a PG1 box haha! I'm sure someone else will be able to try work it out.
Eitherway I'd advise you to go for a PG1 conversion when your box does give up to ghost, extremely easy to do![]()
Sorry to drag it up but only just seen this. Those are interering results, as you know mine is a very similar setup bar me running a standard exhaust manifold, no ZandF remap and a VVC inlet and I ran lower BHP figures with less transmission loss (although it was still a fair amount) but higher torque, which was slightly better than a stock 1.8 iirc. My torque curve is also much smoother also.
Did you come to any conclusion as to why your torque is wibbily wobbily?
At the time for my exhaust setup I was running a stock manifold, with a baffled decat and a metro GTi catback exhaust so I think I might have gained a HP or two if I had my Scorpion exhaust on, and my gearbox is, touch wood, as good as ever so that may have helped my curve.
