You'd need to be using like 3.5 L/100 km or less to come out ahead the speedos in older cars can be pretty worn out and not keep up with the actual wheel speed.... 3 1 Quote Link to comment Share on other sites More sharing options...
Alfashark Posted May 8, 2018 Share Posted May 8, 2018 And? Once a year you go out and spunk a wad on RUC and forget about it. Then you just kick back and enjoy the $4-$5/100km. Quote Link to comment Share on other sites More sharing options...

Seedy Al Posted May 8, 2018 Share Posted May 8, 2018 However my issue with lpg is having to know pretty much where ever gas station with lpg is in the country. Unless its duel fuel. Then sunglasses.jpg Quote Link to comment Share on other sites More sharing options...
kws Posted May 21, 2018 Share Posted May 21, 2018 I know its a shitty pic, but would anyone have a clue what the bellhousing on my spare LT77 gearbox is? Looks to have an adaptor plate and no obvious markings. The biggest give away for me would be the hole in the top, and the two studs which i presume are for the slave cylinder. Its not RV8 or 2600/2300. My google-foo isnt working on this one. Quote Link to comment Share on other sites More sharing options...
Transom Posted May 21, 2018 Share Posted May 21, 2018 Show us a photo of the bolt pattern side ? Quote Link to comment Share on other sites More sharing options...
kws Posted May 22, 2018 Share Posted May 22, 2018 Can do. The adaptor plates are very home made. Quote Link to comment Share on other sites More sharing options...
kws Posted May 22, 2018 Share Posted May 22, 2018 Looks similar to some rotary/13b ones? Quote Link to comment Share on other sites More sharing options...
Transom Posted May 22, 2018 Share Posted May 22, 2018 Yes that's what I was thinking maybe earlier 12a/ 10a ??? clutch fork and starter hole looks similar to mine but I'm not an expert just thought bolt location and clutch slave location looked rotary Quote Link to comment Share on other sites More sharing options...
kws Posted May 22, 2018 Share Posted May 22, 2018 ding ding ding, early rotary of some sort. This is an RX-5/121 gearbox Now, what sort of saddo whacks a Vitesse V8 LT77 box behind a rotary?! 1 Quote Link to comment Share on other sites More sharing options...
Alfashark Posted May 22, 2018 Share Posted May 22, 2018 Maybe some saddo slotted a rotary into a Vitesse at some point, creating the British equivalent of the Roadpacer in the process. Behold the Roadleisurelystroller! Quote Link to comment Share on other sites More sharing options...
Transom Posted May 22, 2018 Share Posted May 22, 2018 Or if it has an adapter in front of that maybe the Rotang part was just the right length and easy to adapt between the 2 and has starter and clutch mount made easy ??? Quote Link to comment Share on other sites More sharing options...
HighLUX Posted May 24, 2018 Share Posted May 24, 2018 Paging @RUNAMUCK supercharger barry Pickapart has a kompressor merc in the yard at the moment. 5 seconds of google says its an eaton m45. Your thoughts on such a device of crank driven forced induction please? Quote Link to comment Share on other sites More sharing options...
Yowzer Posted May 24, 2018 Share Posted May 24, 2018 2.3? If so I'm pretty sure it's a M62, about 1000cc/rev. But then maybe not. I have a m45 off a mini that I was tempted to put on something silly. They have some coating on the rotors which don't like drawthrough carby setups, but they are lots more efficient than the Toyota two lobe jobbers. I think ya can spin them up to about 14k if ya want to. 1 Quote Link to comment Share on other sites More sharing options...

HighLUX Posted May 24, 2018 Share Posted May 24, 2018 C230 sedan. Yeah I was thinking they would be more efficient than an SC14 so can make boosts with less heat/more boosts. Getting it off the Merc looks real fun Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted May 24, 2018 Share Posted May 24, 2018 The Eaton chargers have helical.rotors so they don't pulse as much. It was my understanding that the size is their displacement in cubic inches. They're more efficient too or something. I've got an Eaton m62 which was factory fitted to a 3.3ltr. Quote Link to comment Share on other sites More sharing options...

RUNAMUCK Posted May 24, 2018 Share Posted May 24, 2018 If it's a m45, drive it at 2:1. Your motors swept volume per Rev is 1000. Spinning 2:1 (assuming 45 cubic inches swept volume on the pump) you'd see 1500cc per Rev. So you'd be jamming half as much air again in as the motor can breathe at atmospheric pressure. Which shouldn't be crazy psi. Other factors include how efficient (or how worn the coating on the blower rotors are/ it might not achieve its original rated displacement) and the VE of your engine. That is the intake tract restriction. Say 2zz when it's tec'n (or whatever Toyota call it) will allow the incoming air into the cylinders much free-er than some other asthmatic engine with tiny ports/little valves/restrictive intake design. Same goes for the camshaft profile. A bigger cam (monster cams for everyone!) Also helps allow more of that charge get into the cylinder too. It's not just jamming more air into a smaller space, but it's getting it into that space too. Due to the zero lag with a blower monster port size/very free breathing heads aren't so shot as on an NA motor. Because instead of relying on the motors suck to draw in the charge (14.7psi at.sea level) the blower is forcing it in. So the low port velocity often yielded by high rpm compatible/big cam engines is quickly.overcome. Soz if.I'm. Repeating myself. What flavor of 2ltr you gonna make.awesome?
