Homemade Acura V10

[twizt2]

Hi all
I woke up from a crazy dream last night with an idea. For a second forget about the cost constraints and let's just discuss the theory.

Is it possible to take a C32 powerplant and either configure 2 of them into a W12 formation or actually combine 4 cylinders from one C32 to the existing 6 cylinders of another?

Obviously, that is just the head and block, but most everything else is going to be available from the 2 complete donor engines.

What other issues have to be addressed? Drivetrain, chassis (additional weight), mounts, fitment, etc.,

Unfortunately, my dream was long on excitement, but painfully short on details. :biggrin:

Thanks,

Twizt

When you go night night tonight, try and shoe horn one these in there instead,

Being from the Clearwater area, I'm sure you'll have no trouble finding a 6 + 4 NSX powerplant conversion specialist that can address all of your integration concerns.

It would need custom-made cams and crank. Nice to think about but don't think the engine bay is wide enough for it to fit.

Yeah, I had similar dreams before (do we both eat too many Fruit Loops?) and went even further, but with 4 cylinder engines.
If you put your engines inline as I imagine, the first problem (besides space, but as you said we’ll overlook that) is if you transmit the power from engine one into the nose of the second engine, then the second engine will have twice the power going through it and might break at the flywheel.
So if you put them in a side by side, then the clutch gets difficult because you have 2 clutches which need to be engaged at the same time, not to mention shifting the gearboxes.
So to your W type engine. If you make new block, then you also need a new crankshaft because those extra rods won’t fit on a standard crank. So you end up making almost everything new.
Take a look at the kitcar guys in Britain, they use two 4 cylinder motorbike engines to make V-8s. Beautiful. But they end up only using the original heads. That is what would happen to you too.
Now… I have designed a way to economically mate four 4 cylinder engines together to make an H-16 and figured out the transmission too. Won’t fit in an NSX though… Next summer’s project. I can’t wait to hear what a 16 cylinder engine sounds like!

In early 70s Porsche was working on 16 cyl. I think the engines met rear to rear and some common shaft came out of that to drive things. I thik it was only at the prototype stage. Was in the 917 uber car era.

O common, you guys must have heard of this car.

Is it just me or does that car look

wow...i really thought i was going to be the lone psycho on this one. Glad to see a few of my fellow delusionals chiming in. :wink:

miami - shoot...that would be tooo easy...no challenge there....:wink: ...mmmm tasty mmmmm....

John - clearwater has more than its fair share of builders, but most are used to working on domestic engines, so i'd have to have a very strong idea of what exactly i need them to do. Are you from Clearwater?

dquarasr - If you really want it to fit....you can make it fit...i'll just have to ride on the roof that's all...

710 - You, my friend, are a true nutcase. :biggrin: But let's say that the W12 route was the path chosen. I would expect that constructing new components such as a block, crank and cams would be part of the program.

My question is would the w12 configuration fit the nsx engine bay and would the myriad issues that Honda engineers faced setting up the chassis for the c32 v6 have to be revisited to make sure the new wunderkind engine doesn't completely overpower the chassis?

Thanks for all the great replys!

You would be best off attaching 2, 2.5L 5cyl honda motors together to make a V10....while we are dreaming...that was the rumor when i worked for acura as to how they were going to build a V10 for the "new Legend"...wich turned out to be a 6cyl RL:frown:

 

[710]

Nutcase here,:wink:
I also though of the “more power” issue with my nsx.
$15,000 from SOS for a 3.8litre upgrade? Nice, but way out of my price league considering I paid €25,000 for a WHOLE nsx including motor.
Sooooo, more power needed, maybe 100hp? $9000 for a supercharger? Nope, too much again.
So I thought of putting a cheap 4 cylinder alloy 4 valve engine that produces about 125hp (cost about $100) IN the engine bay, on top of the engine. Hell, people put a supercharger up there and far from getting laughed at, everybody goes ooooooh.
Then i looked under my car and see there is a colossal amount of wasted space under the trunk. The exhaust system (stock and aftermarket) waste a truly obscene amount of space under there. Repackage the exhaust system to run only along the sides, and put the auxiliary motor under there.
A flat 4 engine would be good. Air cooled even better but then, gives less power.
I would connect the auxiliary engine to the V6 via a specially made front pulley via motorcycle chain. but packaging problems would dictate a drive shaft and 90 degree box. Hey, maybe I could use the the stock clutch that come with the 4 cyl. engine.
I think the NSX crank could take 125hp extra, anyway the aux motor would only engage a high rpm so the stresses would have less effect.
Let the aux engine idle most of the time, but when power is needed, the clutch in the special pulley closes. Say at full throttle. Vroem, 125 extra horse power, which requires NO change to the existing NSX engine! No remapping, no rebuilding with high or low compression pistons. Only a (clutch) pulley or drive shaft. And the whole thing can be taken off when/if the car is sold.
So now I’m looking for a small, light flat engine. Airplanes have that, but they don’t produce much power.
Also for those of you that want even MORE power, just turbo the aux motor. Cheap and if it blows up, get another one from the junkyard.
What about a bank of weed wacker motors? Naaw.
Yours truly,
Nutcase.:biggrin:

Put them side by side, connect them with gears and you have an H-10. Show Honda how to do it.

reminds me of the infamous Bugatti Veyron..

[twizt2]

Yeah, the W16 configuration is insane...before the add the turbos...4 of em. Yikes!

Back to my pipedream for a minute: Anyone have any thoughts as to the NSX chassis's ability to handle a v10 or v12 with a hp output of approx 550-600hp and the additional engine weight?

This isn't about just hp output. There are far less expensive, tried and true ways to have a fast nsx. This about giving the NSX the only it lacked from the factory, an exotic powerplant.

Thanks for checking out the thread and making comments.

How about a V8 Hayabusa:

http://thekneeslider.com/archives/2005/11/01/hayabusa-v8-for-the-dp1/

I like the concept here, 383 HP, and 210 lb. power plant. My CTSC 3.0 L weighs about 500 lb. and puts about 400 HP on a good day...

How about a pair of 2 L Civic top ends into a V crank case, dual turbos. the Civic tuners are getting 300-350 HP with out the motors blowing up(very often). I would take a 4 L, 700 HP V8:biggrin:, just need a custom crank and some funky block...

I checked out the busas. That is ridiculous. Insane performance potential. Check this out:

http://www.zcars.org.uk/ultima/index.htm

Not exactly what I'm trying to accomplish but cool anyway. They take a ultima, yank the chevy small block and replace it with 2 busa powerplants! 1000hp + all wheel drive. Power to weight should be impressive. Must be nice to afford to make any car you desire.

Thoughts?
