Let's all get on the bandwagon (circus wagon?) and pitch in to get a new class in the Gas Roadster category -- Roadster Sidecar classes. Maybe even more useful than the recently-new Compressed AiR Roadster class (C/AIR).
See illustration herewith . . .
Oh well -- it won't post. Says it's too large, but it isn't. I'll send it to the good doctor and maybe he can post it.

I haven't seen the picture, but if a side car will help keep a roadster pointed in the right direction . . .
well . . . that might take some of the fun out of it.

Stan, I would think one of the class requirements should be the sidecar roadster must use a motorcycle motor... and the largest class would then be F not C.... The big problem is those smaller classes... can you imagine how long it will take a 50cc sidecar roadster to get to the traps :-o
Open another box of wine...and we will talk about this more :cheers:

Time that it takes to get through the lights shouldn't be a problem, Stainless. The new class is designed specifically to run on the Course #7, which is the perimeter road between the salt flats and the interstate. The lights will start with one 300 yards from the start line, followed by another (making the first timing trap) at 325 yards. The final light (there'll only be one "real" timed section will be from the 325 all the way down to the 500. That'll make conversion from time to MPH pretty easy. All the timer will need to do is relate the distance of 175 yards to miles, which is simply multiplying time by .00994318 or something.
Got it?

Stan you aren't you 107 days correction 106 days early??
-
I'm trying -- I'm not lion!

A Turbo Hayabusa powered sidecar/roadster sounds great! :-D

Right down your alley... I'm sure the Noonan Moreland team could have one together by April 1st :-D
-
I would like to see a trailer addition to every class. Like AA/BFS-T.
Ok.... I know what you're thinkin!! The chutes will get tangled in the trailer so they could go "on" the trailer. :-D :-D

Would that trailer have its own engine and "driver train"?

Only Streamliner & Unlimited Diesel Truck can use more than one engine. Rule 2.A.

Let me diverge from the roadster discussion and ask about the Ultd. truck class and the engine Carl Heap had in the Phoenix, and I think the Joint Venture Freightliner has one, too. It was billed as a "16V72" Detroit Diesel. To my knowledge that engine is a real single engine -- that's comprised of a pair of 8V72 engines back-to-back. It was relatively common to use the big 16-cylinder engine for stuff like go-karts and mini bikes and - - what? You're kidding -- that isn't what the engines were in? :roll: Sorry. I've been led astray.
Back to the 16V72. Since it was a pair of 8's bolted into one, and since it was available from the factory as a 16 cylinder -- is it considered one or two engines? Obviously I don't have a reason to ask other than just for the sake of knowledge. Any certain knowledge on this? Thanks. :? :-) :-D
-
I thought the 16-71 and 16-92 engine was a true 16 cylinder block and crank with 4 of the 8 cylinder heads and two intakes and what not.
-
Rich, I yield to your greater knowledge of the engines. Now that you remind me -- I think that indeed, I should have said 16V92. Maye the "2" in that label is what caused me to modify the 71 into a 72. Whatever, I'll go with your idea 'til someone comes along with definitive proof. Thanks.
Maybe I'll go Bing-ing and find out what I find out. :?
I've found some stuff. The 16V92 is the biggest model available in the 72 cu in/cylinder size, which runs from 4 through 16. Taking a look at the engine's line drawing I see what might have got me going in the wrong direction, though - - there are four heads, just like Rich said, bolted onto one block. The two heads end-to-end threw me off track, into thinking that a pair of engines was tied together.
Interesting is that the 1472 cu. in. engine is rated at 1350 hp at the shaft at "maximum" and 1254 hp at "intermittent-maximum". But neither of those numbers is enough to power the Phoenix or Joint Venture to well over 200. Anyone remember if there were/are estimates of the horsepower output of either of the engines? We can go back to sidecar roadsters if you'd like, by the way. :cheers:
-
It gets a little confusing if you're not a Detroit guy.
6-71 is an inline 6 with 71 cubes per cylinder. A 6V-71 is a V6 with 71 cubes per hole.
There is both a 12V-71 that is one block/crank combo & one that is two V6's together.
71 series engines were available in 1-2-3-4 & 6cyl's as inline.
The 92's come in V6 & V8 & the The 12V & 16V engines are doubles from the factory.
The 12V-149 & the 16V-149 are single block single crank.
In fact the turbo's on my liner came off a 12V-149.

GMC also had an unblown gas version in the 60's called a 702. A pair of 351 V-6's that were used in the pickup trucks hooked together and used in larger applications. I think one of the uses was to burn a lot of excess gasoline. :-D
Doug :cheers: :cheers: :cheers:

Having helped threads stray from subject by the hundreds I feel compelled to help this one get back to subject.... so anyone have any ideas how fast a sidecar roadster might go with one of those 16V92 diesels is it... lets start with stock... 1350HP and let our imaginations run from there...
Hey Stan, pass the wine box will ya, I feel like you are trying to drink all of it without FeRd's or my help :roll:
-
Did you look closely at the specs for the 16V92? It'll take a long course -- a very loooonngg course -- to allow the car that's powered by a 5900# engine -- to get up to speed with only 1300 hp.
-
If the engine can be set over the drive wheels by using a V-drive traction problems should be eliminated. :-D :-D :-D
Pete
-
Can the engine go in the sidecar? :-D
-
SSS there are a lot of really heavy cars out there running with that kind of HP...
Weight = Traction same formula applies for bikes and cars...
So Stan... what engine classes are you going to allow in this new roadster class
-
I looked it up and the parts book shows a front and rear block as well as crank. Plenty of used 16-92 engines for sale on line
-
Let's open it to all Fuel and Gas classes.
With the C/AIR formula around for a year, it's apparent that no one wants to resurrect an old one or build a new one. Every one I've seen or heard of has been a currently-run roadster modified for fruit gathering (cherry-picking).
-
I like that new term "fruit gathering". It's so much more refined. :-D :-D :cheers:
Pete
-
How else is one to get a record with out the aforementioned "fruit gathering"?
I like Stan's idea. Maybe I'll shelf ole Hank in favor of a side car roadster. I'll go one further and actually use compressed air to power it! :evil:
-
Nope - it's been done already (compressed air power, that is). A French team tried it a few years ago - on a bike, wasn't it? It didn't work all that well, especially since they seemed to be spending a lot of time at the line "warming" their motor. I thought of that warming as a big waste of their air reserve, especially since they didn't have the vehicle hooked to a compressor in the support truck - or anything.
So if you're going to build for the new roadster sidecar class -- look elsewhere for your power source - unless you're willing to be just another Joe giving old technology a try. :evil:
-
Now Slim, that is funny!! :-D :-D :-D :-D
