Default Twin Engine Coupling (How Do You Get Two V8's In-Line?)

I know one of you's is building a twin engine inline V8 dragster or hot rod. My question is how did you connect up the motors? How did the old guys connect up the motors? Any pictures? Any build pictures?

For two in line, I'm told by someone who ran one in the '60s (two injected flatheads) that he used two large gears of the same size. One at the back of the crank on the front engine, and one at the front of the crank on the rear engine. He brought them together and wrapped it with double roller chain just long enough to go around. This secured the two gears together face to face and linked the cranks together.


Edit:
Ha! I think the owner is here on the hamb, here is his page:
http://www.norbsplace.com/page3.html
with the info. I traded some email with him a few years back.

Goes to show you everything is already here on the hamb.

Double row chain and a couple of sprockets is one way, ive collected up the stuff to do it with for a "future" project.

I think the # 1 cylinders on both motors would fire @ 45 degrees apart..... Or something like that...

Alignment is the most important thing. The engine mounts need to be adjustable and allow the engines to be move sideways and up and down. Shims and feeler gauges will be required and a lot of time and patience. There are all types of couplers for motors and pumps. McMaster Carr is a good source for couplers.

I have used a rubber hose and hose clamps on some small applications.

When we were kids, some of the toys used ball point pen ink tubes.

I am building an inline twin, at first I was going to go with the two sprockets and double chain route but when looking for the box to rearend coupler I found that I could get male and female blank rings, these are as I write this, being fitted to flanges that will bolt crank to crank so the front engine will slide in, it will now be far easier to take apart and timeing between the two can be ajusted by ether the moveing the coupler round a tooth (18 degrees per tooth) or if it needs more we can offset drill the flanges, heres a pic of the rear coupler, Ill post a pic of the middle one when I get it back from my machinest frend trevor,

What kind of adapter is that? Looks like a couple of transmission bearing collars. This link was posted on another thread: http://www.dodge-pt.com/pdf/brochure...nts/BR4000.pdf Does this coupler look like a better fit?

The engines do not need to be timed together.

As stated above... They are timed to fire @ 45 degrees from each other on the # 1 cylinders...

It's not necessary. It will run just as well at 5 degrees, or 40 degrees. It may sound different, but the output is the same. The engines do not have to be the same size, or the same make, or the same number of cylinders.

Now I'm confused...

There would be alot of stress if my engines were blown but sadly their not, so we have just hardend the key, we can add more keys or bolts if anything shears but should be ok with mine, I wanted the engines as close a possible so we are useing these couplers from mark williams,

45* is not really the best.It's hard on cranks and bearings. I always recommend going with 10*. What your looking for is 8 long burns instead of 16 short ones. It's really all about the harmonics between both engines. Look up Toymakers thread he set his engines up @ 10* check his video of his engines running.

Actually 296moon, you're coupler idea is a pretty good one. You say that Mark Williams makes those? Does he have a website?
