Briggs & Stratton V8 part6

A little update on the project. Oil pressure release valve added. I have made an adjustable main jet for the carburettor and of course TESTRUNS!
Next step will be new pulleys. Changing the gear ratio.
And I'm working on a transistor ignition

[@171apples171]

Kinda sounds like it might have a flat plane crank in it. This is so badass. I see you have a distributor too. If wasted spark is easy to do on this design, I've adapted more than a few Chevy HEI modules to different engines. You can use an ABS sensor for the pickup on the crank. I hope to be even half the engineer you are before i die hahaha merry Chistmas

[@Skwisgar2322]

You can see in other videos that it is flat plane. Makes sense as that is the easier way to make one.

[@Bustedkuhnuckles]

Abs sensor works for pickup on hei distributors? I’m assuming you have to weld a magnet too

[@policerKJO]

Sounds like an old flathead ford

[@dukecraig2402]

@@Bustedkuhnuckles No, the magnet is in the end of the sensor, all it needs is something made out of a ferrous metal with teeth sweeping past the end of the sensor for it to work. The ABS sensor for the back brakes of a Ford Ranger pickup truck I had mounted in the rear end housing and used the teeth of the ring gear to sense rotation, if the ring gear stopped the ABS system knew and took over the pressure to the rear brakes, some GM cars have the sensor built into the front wheel bearings, they're the ball bearing type and as they rotate past the built in magnet sensor it knows the wheel is spinning. Electronic speedometers in some vehicles work the same way, the sensor mounts in the tranny case and uses the teeth of the main drive gear sweeping past it to know how fast the driveshaft is spinning so it can display the road speed.

[@oantech4252]

Nice job.. keep going with the fine-tuning.. Sounds a little flat on the throttle. If it were a small block Chevy, I would say check the accelerator pump linkage position. Try another hole. Also advance the timing until it pings at accel, then back it off slightly from there.

[@Desmouffe]

My Weber carb don't have any accelerator pump ( Fiat 600 196?) But the timing is an issue. No vaccum clock on distributor. And the centrifugal weights dont seem to work. So when it runs nice on idle 10 dgr adw it does not change when I try to rev it up, so I need to look on that.

[@plap.]

This popped up and is my cup of tea. Very cool, great work. Haven't seen other videos on the build yet and not sure of the displacement just guessing starting with the smaller motors for parts its over a liter and from the carb issues and the sound i'm thinking it needs more carb, more cfm. It is starving. It will keep you bouncing back and forth between idling, throttle response and top end runability. It is awesome and once dialed in it should boogie

[@Desmouffe]

8 x 150cc 3 hp lawnmower engines

[@plap.]

@@Desmouffe 1200cc and with more carb it will be better than the sum of its parts. Their ratings are at low rpm, I believe 3200 or so. Revved up to 5 or 6k she should make some good power, way better than 24hp. Just an awesome job, too much fun

[@Desmouffe]

@@plap. The carb is from a Fiat 600 196?. 600cc and revs about 5-6000rpm. My motor is 1200cc and revs about 3000 rpm. So I hope it will run nice when it's adjusted. My problem right now is the distributor. When I adjust the ignition timing to 10dgr at idle I want it to be 25-30 dgr when I rev it but that doesn't happen. Have to check the springs and weights.

[@plap.]

@@Desmouffe can see the ignition to be fun dialing in too. I think you are underestimating the rpm a bit. Those engines will do well beyond their governed setting without issue. That's just for operational speed hp ratings and guarantee the 3000 hour average service life on equipment. Did tractor pulls years ago and we all removed governing all together and added foot throttles. They would easily do 6k rpms all day long to get some wheel speed up pulling 3000lbs. Never saw one blow. Hearing them spun up higher than normal takes a minute to get use to but they take it. In your case because of all the time invested and being one off I would have a rev limiter to be safe. They will rev to the moon if you let them

[@C-M-E]

This is a rather fascinating project I most certainly will have to go back to the beginning to see where you started. There's a few suggestions I'd offer for optimization, but I'm sure you know where the weak spots are that need a tweak. The easiest to handle would be to open up (read 'stretch' your wall diameter) your exhaust runners to get a more aggressive sound and better flow that one might expect out of an essentially flathead V8, especially the exit pipe section. Back pressure is essential for these engines, But, balancing between bp and getting good flow has more potential than just sounding good.

[@Cougracer67]

Why is back pressure "essential"??

[@C-M-E]

@@Cougracer67 It has to do with how the valve system works versus in an over head cam engine. With the flathead valve arrangement, backpressure helps keep the intake charge in cycle longer rather than blowing out of the chamber as soon as the valve opens. TLDR version: more efficient, more power.

[@jonathoncouchey7151]

Just, a tip if you ever wanted to make some more power on this. The Intake and exhaust can be tuned to sonic ram the next charge of fuel depending on rpm. By changing the length of the intake runners. And the scavenging effect of the exhaust as well. Set yourself up for a torque cam grind for about 2500 rpm and you could have yourself a torque monster.

'Old School' problem.. usually solved by dual carburetors. Middle cylinders are richer than outer cylinders..of course tuning dual carb/s need accurate fuel flow gauges (meters) and even vacuum gauges. I would suggest a longer manifold with some baffling to break up the straight flow. Of curse there is the option of individual port injectors (and a turbo) and then here is the cooling problem .
