Re: home brew quarter sprint

A little update on what's happening here. I'm actively shopping for the right engine at the right price for this thing. The plan is for independent suspension front & rear. Set up to run on asphalt & to turn both right & left. Been reviewing this book which I've owned for 20 yrs, at leas...

Re: Ferrari 330 P4

When looking at a full screen blow-up of your diagram, the bellhousing/clutch can/scattershield between the engine & trans (what ever the proper Ferrari term may be) seems quite long. I assume that there's no way to shorten it to help correct the alignment of the axle?

Re: home brew quarter sprint

Little more shop development. Boxed in around the mill to help with chip containment. I broke down all of my benches & shelves when I moved & I've still got some odd sized pieces for stuff like this. I build with screws rather than nails, so it all came apart very cleanly & easily. Plus,...

Re: Ferrari 330 P4

Re: home brew quarter sprint

Getting settled into the new-to-me house & finally some time to start setting up the shop.

8' of new bench space, a build table in the center with access from four sides & a table for my benchtop mill.

And, my buddy & administrative assistant, Lou thu DAWG.

Re: home brew quarter sprint

Thanks CAL.
Haven't been around much lately.
In the process of moving.
New shop will have 5X space of where I've been working. :) !!

You do really nice work.
Are you replacing the green one with this?

Re: Ferrari 330 P4

I'm an old school guy who builds stuff out of my head & with simple dimensional drawings.
Very interested in how design & engineering is executed at the next level.
Any thing that you would find yourself willing to share would be appreciated.

Re: Ferrari 330 P4

Have been admiring your chassis design.
Are you calculating roll center, cg, polar moment of inertia etc in it's design?
Really dig your machine work.

Re: home brew quarter sprint

Yes, quite a bit of power. I'm overbuilding it structurally to accommodate the power. For comparison...a 410 winged sprint weighs around 1400 lb wet, with driver & is powered by 800+ hp engines. This gives a power to weight ratio of 1.75 lbs per hp. If my build weighs 150 lbs & has 35 hp, th...

Re: home brew quarter sprint

Over the weekend, I looked at a nice 750 inline Honda 4 with 5 speed. Price was very attractive. If it had been a few inches smaller, dimensionally, I would have probably brought it home with me. After quite a bit of research, what I think I'd like to use is a ninja 250 twin by Kawasaki. 4 stroke, o...

Re: home brew quarter sprint

I'm adding an inner set of rails to manage the engine, driveline weight & torque. Will be lightened to match the sides of the cage. What I have shown here is 14 lbs. Not sure what driveline weight will be. I'd like to see a total vehicle weight of around 100 lbs, with at least 20 hp in power...c...
