(Max rated rpm is 2800) The screw is wound pretty much all the way "in" and has a security crimp tag on it. So i should back the limiter/stop screw off a bit and see if the rpm's rise. An extra 150 rpm will be like 8 knots so i'm pretty keen to try as it only does ~25knots now. It was built/owned by the airport rescue people who would be pretty conservitive, interestingly the hand throttle lever could only ever reach 75% of travel before being limited by the injector pump stop screw which i thought was really gammy and hard to drive so i modified the pivot point. They make the "pleasure boat" version of this motor with a different turbo that makes an extra 150hp, so if the screw doesn't make it go faster ill swap the turbo. Dunno about jet boat hulls but a normal hull has a cruising speed. you can tip double the juice down its gob and get 1/2 knot more speed. also, the pleasure boat motor will probably have different cams, fuel pumps, injectors etc. as well as turbo. I have seen same series of motor in pleasure boat and Genset application. 60l sump and 50 hr oil changes, double the horsepower, 40% duty, vs 150L sump and 750 hr oil changes making 1/2 the power at 100% duty cycle. Apples aint apples. Just filled the day tank now, 9500L for 24 hrs on the 2 stroke diesel V8. What do you think about that greta 4 Quote Link to comment Share on other sites More sharing options...

What do you think about that greta She is a planing hull, with enough power it will go faster and faster until it topples off its chine/r.i.p I had a look through the manuals and it just seems to be the turbo that’s noteworthy, bigger picture this motor needs to be replaced with something more modern and fuel efficient, being eco unfriendly is too expensive when there’s plenty of re-man mid 2000’s common rail marine engines on ebay 1 Quote Link to comment Share on other sites More sharing options...

Srstarlet Posted July 21, 2021 Share Posted July 21, 2021 So not sure if this is the right place for this, but after a bit of advice. Years back I bought a few 215/50/13 Bridgestone eager brand new cause "eagers". Fast forward 10 or 15 years still have them unused never fitted to rims and no use for them, lots of people want to own them, but I've got no idea what they are worth. Anyone got any ideas?

cletus Posted July 21, 2021 Share Posted July 21, 2021 I bought a set of new 14" ones about 10 years ago and I think they were $250 each or thereabouts But 13" ones were not remade as far as I know and are now super rare so I guess you could ask whatever you like? If someone wanted to do a period correct car with 13s they would be a key ingredient 3 Quote Link to comment Share on other sites More sharing options...

If someone wanted to do a period correct car with 13s they would be a key ingredient I asked 1 of the people what they would pay and they said "oh ah around 500 each" which really started me wondering what they are actually worth. As you said though, ya can't get them anymore, so price just comes down to how much someone wants them I guess. I think I'll just go with the highest offer between them and be done with it, someone may as well get some use from them Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted July 21, 2021 Share Posted July 21, 2021 Ove heard of people paying silly sums for worn out ones even. Maybe @Cullen might have an idea? I know he runs them on his Mazda 1 Quote Link to comment Share on other sites More sharing options...

Cullen Posted July 21, 2021 Share Posted July 21, 2021 Hens teeth now. Upwards of $2500 a set probably. I contemplated offering my set up for $2000 at one point. Maybe ask $750 each and see what the consensus is. Crap tyres. Should probably just burn them or put on the silage. 5 1 Quote Link to comment Share on other sites More sharing options...

One of the reasons mine stayed brand new was due to the fact of how bad they actually were. I'll put a high price on them and see how it all goes.

chasinthemirage Posted July 21, 2021 Share Posted July 21, 2021 Semi ling but not really worth starting a thread, has anyone mucked around with the Holden 3.8 motors? Pretty keen on another fun car but priced out of VL's, VN SS' etc. Seen a few people in Aussie with turbo 3.8's, anyone done it? Just want a fun street car that I could do the odd skid in/take to the drags occasionally. Thinking 255's, LSD and a turbo (just want it to do hektik doses tbh). Sound plausible or nah? Also inb4 V6's are yuck. 3 Quote Link to comment Share on other sites More sharing options...
87creepin Posted July 21, 2021 Share Posted July 21, 2021 Sometimes if they've been stored well, there will be no cracking to speak of. Hard yes/maybe but will appear to be mint. Quote Link to comment Share on other sites More sharing options...

chasinthemirage Posted July 21, 2021 Share Posted July 21, 2021 It's definitely getting that way, there's still the odd one around though. On the cusp of being unaffordable though too. Quote Link to comment Share on other sites More sharing options...

BA falcon with barra would be better? but in reality really better doesnt matter as long as it doses and skids to your satisfaction moo is still going to moo though also I would note you need to put as much thought into the gearbag/diff holding and putting down the power as the turbo stuff. autos can usually hold the power and put it down but may need some fettling of electronics or valvebody type stuff depending on the box. 1 Quote Link to comment Share on other sites More sharing options...
