For those running the G50 gearbox, which/whose clutches do you like (or dislike)? push/pull type? organic/metallic/ceramic/kevlar linings? full face, puck, single disc or multi? conventional slave & fork, or hydraulic release bearing?

Dave how about some more info on the flywheel & clutch? Is the flywheel setup for the 1UZ, or the LS motor? Is that the full KEP clutch setup or part Sachs, part KEP? Metallic lined puck type disc, or full face organic? Pressure plate specs, etc.?

Tim, if Enzo were still around, I don't think he'd buy into your description that one of his V12 works of engineering art is "just an air pump". :laugh: For me, the engine is the heart & soul of the car. HP and top speed are just numbers, and IMO it's about how it all sounds, feels, and works...

Tim, you have a cam in block engine, with 2 valves per cylinder, actuated by pushrod technology, which is basically a descendant of the 50 year old SBC, and you're calling a DOHC V8 with 4 valves per cylinder "old tech"? If that's not the pot calling the kettle black I don't know what is? The...

They're not the cheapest motors to mod :sad: and you can't go to Jegs or Summit to buy the parts (most gofast stuff has to be built) But they do sound nice way up there. Since the firing order is the same as the chebbie, they sound somewhat like a SBC up to around 4K; after that they...

Terry if your LS is in at 400lbs, fully clothed, then you certainly have one light motor, and I stand corrected about the weight. And your point about the aftermarket support for the LS is very valid. Just not my cup of tea, however.

As compared to what? An LS or SBF? Too big? It and its sump and accessories will fit in a 700mm cube, making it smaller than a SBF except in width. Too heavy? It's all aluminum, so is one of the lightest V8's around, weighing less than 440lbs with all accessories. Lighter than either the...

Yes, I feel that was the problem. Since then, I understand others have wired them in series and fired them OK. I would question if there's enough dwell time at high RPM to do this, but no one has reported running out of ignition at high RPM with them in series. Another interesting setup might...

I would be a bit wary of the Total Seal rings; if you speak with them, they require a specific cylinder boring & honing procedure, plus a certain surface profile when finished, and they have some specific requirements for ring tension, and engine breakin. At least that's how they were when I...

Something I have never quite understood with the political process is that you can make "contributions" to a politician's "reelection" campaign in order to influence his vote. People do it all the time, and think nothing of it. But in the business world, if you give someone money to influence...

Aren't those the guys (Revolution) that make Fran's gauges? That GPS speedo is way cool.

Jack, the simplified heat transfer formula is Btu/hr = 500*GPM*deltaT, so a lower volume pump can transfer as much heat as a high volume, but with a higher deltaT. However, for engine cooling, we don't want a high deltaT between the top & bottom of the engine or the radiator, in order to...

Cherry Corp make very high quality speed & direction sensors that are ruggedised, have Delphi Metri-pack connections and are good up to 12kHz.

This BMW/McLaren motor really gets my juices going:

I don't know the car in the photos, but Jay Esterer up in Canada built an Ultima years ago and powered it with the BMW V12. Here's a link to his site: Untitled Document He really went above & beyond in his search for lightness in his build. Caveat emptor: these motors are a dime a dozen on...

Ron, the conventional blowers that you mention just don't "package" well for an inline six cylinder engine. Trying to fit a single blower on an inline six requires some very tricky manifolding, and then of course, everything starts growing sideways, and you soon run out of room in the engine...

Ron, the blowers are made by Aisin of Japan, their model number is AMR500, and each one displaces 500cc's. They also make a smaller one called the AMR300, which is a 300cc blower, and a slightly larger one called the EK10, which is 750cc. Max RPM is 15K for all. These were originally packaged...

Thanks Wyoming; your first schematic is actually how I'd planned to drive them, however the drive shaft would have one split in the middle. I understand this method has already been done successfully in Australia on either a 4 or inline 6 cylinder motor. I haven't investigated trying to run...

Ryan at the risk of incurring Ron's wrath for posting about engines in the transaxle area, I'm building a triple supercharger setup for an inline six cylinder engine. To drive these superchargers, I need a jackshaft, and in order to change the cogged drive belts in the future, the jackshaft has...

Thanks Scott, found one that is "almost" right, and will be contacting them today to see if it's adaptable. John
