inark Posted July 7, 2004 Share Posted July 7, 2004 My mates in the process of building an RB20DET powered boat I thought that was pretty cool for something different. Hes already got the engine and is working on it now.. Hes puting a rebuilt and hiflowed T04E on it with bigger injectors and a huge FMIC. I pissed myself when he first told me and thought he was playing around... but hes serious cause i went round and he had the boat there and the engine pulled apart.... should be fun when its done Link to comment https://www.sau.com.au/forums/topic/45384-rb20det-powered-boat/ Share on other sites More sharing options...

Abo Bob Posted July 8, 2004 Share Posted July 8, 2004 Wouldn't you use a water to air cooler rather than air to air? Link to comment https://www.sau.com.au/forums/topic/45384-rb20det-powered-boat/#findComment-924540 Share on other sites More sharing options...

Bax Posted July 8, 2004 Share Posted July 8, 2004 What kinda boat? On ebay a while ago there was an rb30 (carby) all three of em. plus alot of work, i think the figure was around 180hp or kw at the propellor:p on one of those little single person racing things.. the Y shaped ones. That thing would hook Link to comment https://www.sau.com.au/forums/topic/45384-rb20det-powered-boat/#findComment-925617 Share on other sites More sharing options...
Bozz Posted July 8, 2004 Share Posted July 8, 2004 Yeah, what sort of boat? If its a ski boat, it will effectively ruin the boat and make it drive like crap. You need instant and enormous amounts of torque in a boat, from standstill, thats how you pull skiiers up. Thats why almost all boats using inboards are V8's - Mine uses a Holden 308 and it can sure boogie. I couldn't imagine being pulled up by something that took 3 seconds to get any power, it would also be a piece of crap to try control while trying to pull a skiier up. On the other hand, if its a rear mount speedboat with no intention of skiing, wakeboarding or other related water activities, it could be a very interesting job. I'm planning on twin turbo'ing my boat, just imagine the sound of a 5 litre V8 with no muffling, basically straight through 3" pipes from each V, while spooling up two turbo's - you'd be in two heavens Link to comment https://www.sau.com.au/forums/topic/45384-rb20det-powered-boat/#findComment-925746 Share on other sites More sharing options...
Revhead Posted July 8, 2004 Share Posted July 8, 2004 Imagine? There was a twin turbo 454 with open pipes that turned up at one of the dams we used to frequent. It was a friggen unit, had a 3 speed auto behind it too... boogied reeeeeal hard pulling skiiers up (I have no idea how they didn't have their arms torn out of their sockets), then you'd see it almost idling along at like 50 knots next lap around. I think from memory it was called Far Canal or Far Kme or something along those lines... whatever it was, I remember thinking "how appropriate" Link to comment https://www.sau.com.au/forums/topic/45384-rb20det-powered-boat/#findComment-925776 Share on other sites More sharing options...
Bozz Posted July 8, 2004 Share Posted July 8, 2004 Revhead, we have an event down here called the Southern 80 where the whole competition is which team can pull a skiier along an 80km distance up the Murray River. Most of the boats end up having things like twin T88's and bigger on monster 454 and bigger blocks. I think the record was in the mid 30 minutes to complete the entire lap, with a skiier behind you! If I'm wrong someone please correct me here... But man..... words can't describe it, I've got a handful of pictures of these monsters from this year here: www.fullysikmate.com/bozz/southern80 Link to comment https://www.sau.com.au/forums/topic/45384-rb20det-powered-boat/#findComment-926305 Share on other sites More sharing options...

But it was a twin turbo 350 chev pulling close to 1000hp. Looked like the guy had spent all his $$ on the boat coz he a a shitty old xf tow car.
