World's Fastest R/C Car, anyone?

I'm glad you like it. I was going to put an interior of sort but I could not find properly scaled seats and didn't have the expertise to make them. It was based on Losi XXT.

As for this world's fastest challenge, I took a look around the Tower Hobbies website and here's what I came up with. The HPI Proceed looks like a very suitable platform for such a high speed car. I found that the Trinity Novarossi and Sirio racing engines have a claimed maximum RPM of an astonishing 44,000 and around 3 hp. With one of those engines and the optional gear set, the Proceed would have a theoretical top speed of around 134 mph. Now, in realityit would probably be considerably lower, more near the record of 111 mph. If there is some way to get another engine into a Proceed or make it use a 3 speed (like from the Kyosho Mad Force), it is possible to make a potentially wining car. Or maybe there's even a way to get two two speeds in series for four but I have a feeling for such a large space three would be sufficient. One disadvantage of the Proceed is that the engine is mounted transverselly, making it difficult to run a twin setup. Maybe something more like an 1/8 scal off road buggy chassis where the engine is inline and it would be easier to add a second one. Ofna has a car called the Ultra GTP that is like this but made for on road. I think Ofna even has a monster truck with two engines called the Twin Titan. Perhaps the engines could be swapped out and it modified for on-road racing?

The only bad thing about this contest is that RC cars cost so dang much and I haven't even heard of any sort of monetary prize. (Of corse having an RC car that goes over 100 mph would be a prize in itself)
