Cycle World tested a 1968 Cobra in their December 1967 issue and recored 0-60 in 5.2 sec and 1/4 mile in 14.1 sec at 94mph.

"Bike" magazine in the UK tested a '74 T500 and got the following.

Top speed (rider prone in race leathers): 110.7mph

Standing 1/4: 14.4sec (no terminal speed given)

The acceleration figures obtained by UK magazines are typically a little slower than those in US mags, because the UK mags did not use super-sticky dragstrips for their performance testing.

Also they were often done with hand-held stopwatches rather than timing beams, etc, so they are not super-accurate

From past experience, I think you will need about 70 RWHP to get into the twelve second zone. Getting that from a T500 is probably do-able, but not very rideable. Custom pipes are most likely required as well. How much money are you prepared to pay? Some decisions to make, and investigating to do, but thats half the fun. Cheers.

I actually work at a bike shop and we are fabricating everything for little or no cost. The porting and polishing work is being done for free, the swingarm is free, the tire is free and the hydraulic system is free...

so i dont know really haha

Boy oh boy. You are living the situation most of can only dream of. I wish you nothing but good fortune and success in your quest, for you will have nothing but self gratification when you pull off your first 12. It will be glorious. Keep us posted, and some pictures would be cool. Cheers.

I think that some of teh giuys are trying ever so gently to point out that it isn't easy to get a lot of power and it isn't easy to make the bike rideable and that doing both at the same time takes a lot of time an patience and working with people who really know what they are doing and are working with you to achieve a specific goal.

None of this stuff is rocket science, well not much at least, but it sure ain't easy, or we'd all be doing it.

In the US there are a lot of people trying to make pipes and port cylinders, but the number who really know what they are doing is very small and most of them keep themselves to themselves.

The really great guys like Kel Carruthers or the guys working for Kenny Roberts or maybe Stuart Toomey or Kevin Murray come to mind. There are good guys on this board and a lot more that got lucky and didn't do more damage

We have guys here who have spent years in the Empirical school of trying things and learning from the failures and successes. There are others among us who are good with the latest software tools and couple of guys who do both with greater or lesser results.

Most of us have read A Graham Bell and Gordon Jennings and John Robinson and maybe even Dr Gordon Blair from QUB and we are all still learning what works and what doesn't.

Horsepower costs time and materials and the more you learn the more return you will get on those investments. Welcome to our world.

the great thing is I am working with older people who know the 2stoke world and the guy who is going to port and polish does all the motors around here for the races...

im real excited and will definitely keep you all posted
