Performance comparison between MK4 and the 33 Hot Rod

[flynntuna]

Has there been any performance numbers ( 0 to 60, stopping distances, lap times ect.) comparisons done between the MK4 and the 33 hot rod?

[OCCPete]

There's sooooo many variables in building these cars that any comparison of two particular cars would be pretty meaningless overall. Really depends on the engine, transmission, suspension, brakes, tires, etc that the builder chose.

I guess what I'm really asking is whether the differences in wheelbase and track, all else being equal, has an advantage in overall performance.

Heck, I can answer this question..................

Seriously, after owning a Challenge Series car and the '33 in this photo I'll say that there is a difference, and a friendly one, between the '33 and the '65 Roadster. The '33 with its longer wheelbase has a much slower moment of rotation so is therefore more gradual when the back end starts to get loose. Think of Figure Skaters spinning. The '65 Roadster can spin like a skater with the arms pulled in tight. The '33 can spin like that same skater with arms fully extended.

Other than that, they both weigh about the same, have essentially the same weight distribution Front/Rear. It's possible that the Center of Gravity of the '33 is lower than the '65 Roadster because of the frame/suspension design, but we'd have to ask FFR about that.

The performance specs on the roadster are from a real life test (FFR website) and the ones on the 33 are estimated but they are very similar. I don't know if the guys who build the 33s use a single donor as often as the roadster guys but if all is equal, the braking shouldn't be too much different, either. Pete's right: there are so many variables such as high performance brakes vs donor brakes, etc that it would be hard to do a fair comparison. I would like to see a side by side build where the components were as close to identical as possible and then see how the two matched up. That would be fun! WEK.

Yeah but Tom, the Roadster is getting ready to LAP YOU!! HAHAHA

I couldn't resist taking the shot!

Build what makes you happy, and the performance will be what you want it to be, in my opinion... for whatever that is worth.

Hi Steve, The roadster never got past.....

.....my passenger kept lobbing water balloons at him!!!!

Thats a totally cool picture!

That's fantastic!! Water balloons--- man I needed that laugh Tom!!

Thanks for the picture as well as the sense of humor!

Hi RT, It's interesting to see in the photos how the front rocker-arm suspension works on the '33. Note how the lower A arms relative angles to the pavement are quite different in a hard turn.

Hi Steve, Here's the Cousins back in 2010 before I sold the Pumpkin Racer to a good friend, Terry W.

On Street Tires, both cars are really quite similar to drive. I've never driven the '33 on race rubber, but expect it would not be too much different either.

Of course there's RideTech's "Juvenile Delinquent" that would be tough competition almost anywhere!
