2 60degreeV6's mated = V12!

[9c1cruiser]

Hey all....long time no talk. Im trying to figure out this new crazy website...not as much colors and pics as the old aol gpxs site. But anywho, I was at another one of my forum site where the topic of mating V6's came up. Anyway, I think the GM 60degree is the best V6 designs for balance and space...the two biggest issues of V12.
I was just wondering if anyone here knows of anyone who has done this? People mate 350-V8's all the time. If you know of any web sites of crazies who have done it, post it.

I personally think it is waste of time in regards of performance...but it would kick for show and noise, plus being a whole lot cheaper than buying a V12.

Pasta.

(2) 60V6s mated = (2) 60V6s

I modded my GTP to run (2) V6s instead of (1) V12 .. I have the front engine run the front wheels and I fabricated to fit another engine in the trunk .. Im running on an AWD setup with each set of pedals connected to one universal place. A write up is in progress ..

Whee!
But what would you stick that in?

Can't answer your question, but IMHO, I think if GM ever wanted to put a V12 in a Vette the 60 degree V12 based on a V660 is the economical way to go. The tooling is mostly there and get this, two 3.4L v660= 409ci. An echo of the past. The marketing people would have too much fun with this. Two 3.5L v660=427ci and two 3.9L v660=473ci.

GM used to have a V12 made based on a V6 design. The GMC 702ci V12. It was a 60degree design as well. They also made an 8cyl based on this too.

I doubt GM ill ever put anything other than a small block Chevy in a new Vette. There is no reason to really, a SBC can make more than 1100hp N/A. And since so far we are only looking at 500, they still have room left.

[bszopi]

GM has already put a V12 in a Vette. Or was it a V16? I dunno, there is one at the Corvette museum.

[RidgeRunner]

But was that done by GM, or by some aftermarket company? I thought it was aftermarket. (Falconer V12, I believe it was)

I think they should put a turbo'd 4 cylinder in the vette to appeal to the younger audiences. . . .. .

And don't forget, a 4 cylinder with 400hp is much more fuel efficent than a V8 with 400hp *Roll eyes* I hate how stupid my generation is. Just like my Z34 revs at 2300 at 120km/h on the highway whereas my friends GTS revs at 3200 at 100km/h... i wonder which will get better fuel economy, plus with that big fartcan on there its really a nice car for long trips, that drone that drowns out his 2000 dollar stereo doesnt get annoying at all.... sorry, im in a bad mood right now...

But ya, I say they make a V12 out of two 3.4DOHC's, it'd be easy...ish. Thats around 420hp doing ricer math. The engine wouldn't fit in anything short of a 25 foot car, but hey, go for it.

You are right and wrong. A forced induction 400hp 4 cylinder willg et better gas mileage than a n/a 400hp small block, becuz at cruizing speeds you are generally under low, if any, boost.

And IIRC, the GTS were turbocharged. Therefore, at 3200 rpm, at cruising speed/throttle, he is probably under very low boost(1-5psi). I bet that his turbo 4, under real low boost, would get better milegae than the 3.4. Also remember the 3.4 isn't making much tq at 2300rpm. Enough to accelerate sure, but you have to get on it in order to accel, therefore to cruise you will need to have a bit of throttle in it, unlike my dads LT1 where you can idle at 60mph in 5th, and it will hold itself at 60mph.

*EDIT* Also, I do not really believe that many Corvette owners/drivers buy their Vette for the gas mileage.

LMAO is this thread for real!!!!!!!!!!!

[PlatinumZ34]

well its a celica GTS and no its not turbo'd, i helped him rebuild it. It's a 2.0L DOHC. Naturally aspirated, only the AWD Celica's got stock turbos. Both our cars have the same size fuel tanks (maybe 1 liter differance) and i use 1/8th of a tank going to my cabin and back and he uses 5/8's of a tank.

My car will hold itself in 5th at 60km/h so thats close... ....

EDIT* i probably should have told you what kind of GTS it was haha.

GMC had two 60* V6's mated together in the 1960's... If you don't believe me, check out this link.

Check out the torque that big bastard produced at that low rpm.

BTW, I used to own a 1963 GMC 1/2 ton Custom shortbed pickup with one of those 60* 305ci V6's in it, couldn't beat it for reliability(never really had any problems out of it in the five years I owned it).

EDIT:
err, smilingguy already posted something about this..but at least I included a link..

This is an Allison V-3420 24 cylinder. It is basically two V-1710s (mounted on a single crankcase, with dual drive shafts that are linked by a gear-box), which powered the Curtiss P-40, Lockheed P-38, etc. About 150 were made. They powered the xp-58, xp-75 and some other experimental bombers. Displacement of 3420 cubic inches. Almost 3000 hp and a red-line of 3000 rpm. Weighed about 2500 lbs. Has both a supercharger and turbocharger that are really fuckin huge. I know that this is an aircraft engine, but I thought you guys might enjoy it.

Edit: Sorry those are so big, i'll try to find a way to make them smaller. Also, to cite my sources, some of that info is from the dayton air museum. Pictures are mine.

Edit: Fixed size, I think.

Edit: Yep.

could it be because of the way he and you drive differently?

[PlatinumZ34]

Well... I DO get nearly 400kms to a tank (250 miles) in the city and he gets about 700-800 to a tank (in the city), im a much more violent driver than him. Im pretty sure somethings broken that i get such bad mileage... but hey, you win some and you lose some.

so would that V24 be a 120* engine?

[Gemmer]

looks like 2 60* engines with maybe 20*s between them...but since they have two seprate drive shafts, I dont think it matters the overall degrees =P
