Thanks for the update!

Cant wait to see hpw it goes! I bet your excited to say the least!

Out of interest, are the brakes expensive and hard to find?

second hand yes they aren't common, they're around £1600 new, AP Racing do a very similar setup and similar cost.

So a few weeks ago I borrowed a trailer,  and my BMW's alternator died on the Thursday evening just as I was loading up the ZX ready for the Friday morning trek to Launceston, cue DCC's Landrover to the rescue!!

 

this was the view at about 6.30

Bumper off and strapped down.

Dan popped down to Truscotts and got a brand new expansion tank cap, the used one I had didn't seem to be holding much pressure, though it wasn't boiling over at all.

 

big thanks to Neil, he's a bloody good teamaker, as well as Pinto building machine, I'm sure he knocks out two or three a day at least of the hotrod high power beautifully finished engines!

 

oh and Dan picked up some bits from Sandy...

After a few issues with some tricky to find wiring faults causing an injector to not fire, Sandy cracked out his wiring kit and made me a new outer injector sub loom, cleaned the plugs and got cracking, then found an issue with the lambda dropping out, seems the heater circuit was a bit iffy and the lambda kept going full lean, gave that a clean stronger live feed and it seemed to be fine thereafter, once the few niggles were nailed down the map came together very quickly.

only managed to get a few short video clips, no power figure yet but we do know we're at the limit of the GTI6 injectors at 3 bar  (running up to 85% duty IIRC), and the Clio 250cc are filling the rest as required, so its around the 240 bhp mark.

 

next jobs are to sort the clutch cable as it seems to have been cooked with the prolonged periods under load on the rollers, will need to find some material to protect it from the heat, buy some pads and fit my brakes.

Where's the dyno chart? I'm more interested in the torque curve.

no chart, old skool rollers, all it has is a Pair of Dials, wheel speed and power.
