Rosscos GQ Rejuvenation

Nice result ross. For reference though this turbo really comes into its own at around the 28psi mark and 180kw+ area. There is quite a bit of r&d going on up here so if I can get down for licola then I will pass some of the findings onto you and andy.

Yeah nice one. Andy did say could get some more kays on the motor then get some more boost into it down the track. Reckon I'll drive it for a bit and see how it goes but so far very happy with it and also do want to keep it safe for peace of mind and longevity.

What sort of KW would this setup be making at the engine - ie really wanting to know losses thru the drive - just curious.

Its fairly consistent with a td42 and manual box at around 25-30kw loss. So Rossco would be sitting around the 170kw area at the flywheel. Or nearly 230hp.

A bw at 180kw is for longevity. Once we start venturing beyond 200kw it starts to get a little hazier but the way the bw generates boost its much nicer on drive train. Remember you are not always using that amount. There is one up here that has been running 200rwkw+ for over 2 years now without an issue.

So took the GQ over to Cornell Diesel in Sunshine West (fair mission lol) the other day. Anyway since last tune haven't been entirely happy with it and was lacking pull from idle up to about 1200 revs. Also cold start had always been a bit rough on this pump (12mm one) and seemed to be quite a bit worse lately stalling on a couple of occasions and blowing plumes of white unburnt diesel even when it wasn't freezing cold.

Just got it in for a diagnosis at this stage and they found fuel looked very sus with most likely water contamination, said it looked like creek water. Pretty weird only thing I can think of is dodgey servo which could have been anywhere between Vic & WA. Anyway upshot is tanks need pulling out, draining and flushing, pump most likely needs a rebuild and injectors could be suspect too. Need to have a think weather is worth pursuing with this pump or just replacing with another unit such as UFI. Also obviously whole thing will not be cheap can do some stuff myself to keep costs down or look at insurance maybe. . .

Also thought oil feed was leaking on block but looks like one of the exhaust studs is leaking which needs to be fixed too. . . Ah the joys of tinkering with cars
