Projects Toymaker's Twin Engine Dragster Build

I guess I was optimistic about having both intakes tacked but I couldn't lay my ears back and get after it. My Aussie friend would NOT wear his safety glasses and was uder foot all night, here he is doing what he does best................








NOTHING!
But I did get one all cleaned up.......

Log cut-out................

Fitted, tacked and ready to weld.................

The fit turned out pretty well, hmmmmmmmm maybe a call to Lee is in order
And yes the COLD weather has slowed me down but fear not, we are shooting for MAY

 

Hey Rocky...torch brazed our intake and it went very well. Just take your time, (yeah, right) and you'll do fine.

 

Look'in good Roc, great looking fit, take your time.......you'll make it I'm sure of that!

 

Manifolds look cool, are you going to divide the runners? It will make a huge difference to how it runs.

 

Thanks Guy's, I'm gonna run it without dividers at first then add them making individual runners if I feel it needs them.

 

It may not make a differnece undivided. I often though of makng an intake with undivided runners. Now I wont have to. I can just wait for the Rocky Report.
An interesting comparsion is the Chevy six cylinder. Maybe not an exact comparision but similar. Despite all the talk contrary experience shows this design gives up nothing at the race track against conventional twelve ports. I read a lot years ago about bi-factured ports and siamesed joined ports. Even then no one was quite brave enough to step right out and declare anything. Length is right. Port will definatley not be a restriction. It might work better than one thinks. We will see. I find that intriging.

I'm with you Don, I'm trying it first before any changes. My son who is a pretty good welder and damn handy with a TIG but hasn't TIG welded with silicon bronze rod, is there any thing he should know that is different?.

 

After tacking the intake together I tried it on the engines, Damn I'm happy!

 

Damn Roc that looks great!!!. It doesn't look too high. It just will make a good sight picture as you are going down the strip, and "Keep it between the 97's"............

I may not make it to Turlock as I have to go in for shoulder sugery on the 26th and I may not be up to it.......

Course if it don't rain tomorrow its off to test n tune gotta get a try on third gear before I get messed up for a coupl'a months..........

 

Hi Roseville Carl....I really want to go to Eagle Field, Kathy is too young to ever leave on a Flag start. I sure did tho, at Cal Neva Timing Assn. (The northern California predesesor to N.H.R.A.) events at Half Moon Bay, Cotati, and Vaca Valley Raceway. During my high school years. I think it will be a lot of fun to teach her the FLAG. She is pretty good on a four tenths tree. Please introduce yourself in the pits. Tony Lloyd

 

Yea Tony well I guess we need to have a Flathead section set up for us at Eagle, how about it Rocky? A bent eight section! hummm

Crap Roc I just realized there was test and tune today not tomorrow so I guess we have to wait till next sat.......the beat goes on.......

 

You bet Carl, we'll put all the Dragsters together like last time. Take care of that shoulder, we'll be racing soon!

 

Great Car Rocky, Guess i'll have to come down in May to see it run! Keep up the good work.

 

will you not have to seperate the two ends of the log a bit like a tunnel ram has to sometimes have to compensate for not enough compresion?

 

Look forward to having you come down in May motorgod'. There are proven theories I'm sure that my manifold would benefit from but this is 1960 and I don't know them yet
Seriously I'm gonna run it and see what the outcome is, I would like and plan on more compression (currently around 9 and 10 to 1) but it will run pretty much a WOT and driveability (I can't even spell it) is not a consideration plus the Carb CFM is really small. We'll find out. Rocky

 

theories I'm sure that my manifold would benefit from but this is 1960 and I don't know them yet
Thomas Edison once told a group "Experts" that Inventions are made by people too dumb to know they wont work"
I have that as one of my rules to live by.
Smokey Yunick said, "One good experiment beats 1000 expert opinions."
I have found that to also be true as I can tell you have as well.
My German cousin's husband who was a Formula 1 Engine designer for BMV one told me in his accented english
'Don. A leedle beet mehr is always posseebull. "
I have that posted on my shop wall. It was immediatley obvious to me why he had his job!
I am really interested in your design. Keep on truckin.

FYI I thought I'd mention the cam specs on my reground OE REV Engine rotation cam I had ground by Clay Smith. George ground the cam to 231* @ .050 with .480 lift, not much bigger than a mild street cam but I'm not trying to set any records and it is close to the cam in the other engine.

 

Yep, I like that Don!

 

And you can always say they were designed by BYD Engineering (back yard dummies), need to see the second one tacked up and in place with the carbs on it, that also would make my day, or weekend, or whatever...........
as I have been repairing plumbing and sheetrock this weekend and I'm tired of this sh and need an auto fix.......

 

I really wanted to get the other one tacked but a cold has me down

 

I may have to post that on my wall as well. I like it!

 

Question, How do you dial in 3 97's on one motor and 3 on another when they're tied together? If one motor is spittin' and sputterin' how does that affect the other while you're trying to tweek it? Or are we all going to learn together?

Like I don't have my own problems (both mental and physical)!

 

Hi Katuna....Pull one flywheel get it tuned up , then do the other one. I presume Toymaker can put a starter on each engine. . The way I did it on the FH/J car was, initially, separately tuned on a stand then assembled togeather. Once we got the car running, tune up changes were done, while connected. When one engine craps out for some reason, during a pass, the driver has to be aware enough to shut it down, NOW!!

No one ever worried about hooking two horses together and making sure they work exactly the same. Same goes for a lot of things . As long as one is not dragging its feet the combined strength works fine. Far too much worry about making sure they are exactly the same. Any one have a pic of the old dragster "The Odd Couple"?

don

 

Makes sense. Not like you're connecting two Rolexs together.

 

The tuning on this monstracity will have to be all at once shouldn't be a problem as long as I get all the basics dialed in to begin with.
I spread all my stromberg pieces out and between what I had and Carl's 3 I wont need much but man thats alot of small pieces to clean.
Hopefully I'll tack the LH manifold together tomorrow night as I had to cut the RH manifold apart and changed the angle a couple degrees due to being unable to see.
I've been posting on BangShift.com and Brian posted a bit of the build on the main page and recieved some pretty good interest, now it's gotta be done by May No looking back NOW

 

...or ex-wifes...

 

hope this works-if not don pm me i will send it to via email

 

Thanks for the photo PC', I'm hoping to put on a show simular to the near lane not the far lane

 

yeah i think the other dragster was tommy ivo
