Nasty Boy Art

[Randy Forbes]

Yeah, I took the page down a week or two ago while doing some clean up on the Austin-Healey prints. If folks are interested, I'll bring it up to snuff with the other pages and let you know when it's available again (I'm thinking the end of this week).

David, it's always a treat to look at your work__I'm confidently speaking for everyone here__even when we're not looking at our own cars! Just look at how this thread wondered on to the subject of Webers

Here's an updated version of the Nasty Boy I drew for Randy. If anyone is interested in a print of their very own Nasty Boy, you can order any of the Austin-Healey 100, 100-6, or 3000 prints and just specify your modifications in the Special Instructions box. It's also useful to send pictures. I can accommodate most any Ford or Chevy configuration as well as a variety of gearbox combinations (including automatics), wheels and tires, etc. There is no upcharge to modify the prints. https://sportscarart.com

Gorgeous! But DO read up on what David Vizard has proven (with flow-bench & dynamometer testing) about those screens across the velocity stacks.

Just watching Netflix documentary on Jackie Stewart at 1971 Monaco Grand Prix, he had screens over his velocity stacks too. Guess the didn't know either?

I expect they were rebuilding his engine(s) with greater frequency than what would be considered acceptable for a road car too...

I expect the only thing they were concerned about was preventing birds from getting sucked into the engine, but technology, namely in the area of flow-bench testing has gained prominence over the suck it and see mentality of those days.

I'm just stating documented facts, but I'd prefer you not take my word for it, and follow some of David Vizard's work; there's a lot to be learned, even if we can only absorb a fraction of it. He's likely worn a groove in the pavement moving between his flow-bench, dynamometer and keyboard!

Having an A series motor, I' spent a lot of time reading Vizard when putting my motor together (and yes, it has velocity stacks with K&N filters) and just looked to see if I could find anything on air filters. Start the video below at 4:25 to see an excellent discussion on filtration. The statement that an hour's worth of racing produced a teaspoonful of grit in the engine might make you rethink running unfiltered.

Wow, two (2) hours. I'm going to have to set aside a block of time to watch the whole thing (probably should sit on a stool though, and not in my recliner!).

As you may have guessed, my comments above are based on his Tuning the A Series Engine; I'd only recently purchased the book, and I'm still in the cylinder head section now, so not quite halfway through reading it (exceeds 500 pages, but a good read for anyone into building/tuning engines, regardless of origin).

There's a project I want to do in the future, and it involves the Spridget platform, and a fastback body...

Rick,
Thank you for posting the Vizard video, I have not seen it before but I have read and re-read his "Yellow Book" (Theory and Practice of Cylinder Head Modification) like a mechanics 'Bible' for years. Hard to think there is anyone with more useful info out there.
Now, after 2 hours of sitting, I am inspired again.
