Blackbird222 Posted June 30, 2009 Share Posted June 30, 2009 I've been following a long discussion in the locost community about forming a racing class for homebuilt cars (for all the cheap bastards who like fabricating stuff themselves ). Without boring you guys with too much of the specifics, is there any interest within NASA to form a (s)lower ST/STR class with power to weight ratio of 12-15:1 or whatever you guys find reasonable?

Trevor57 Posted June 30, 2009 Share Posted June 30, 2009 Can homebuilt cars run in PT? Quote Link to comment Share on other sites More sharing options...
Blackbird222 Posted June 30, 2009 Author Share Posted June 30, 2009 Some can, my homebuilt locost (Lotus super 7 replica) is legal. I'm building mine for ST2. I believe the STR classes are open to any homebuilt cars (given that they comply with safety rules etc..). Moti Quote Link to comment Share on other sites More sharing options...
National Staff Greg G. Posted June 30, 2009 National Staff Share Posted June 30, 2009 Can homebuilt cars run in PT? No, well yes. The Factory Five cars are for the most part home built, and they can run in PTA. I think that is the only exception. Any home built car can run in STR or SU depending on the Adjusted Wt/Hp ratio. There would not be enough demand for an STR (or ST) class with a higher Adjusted Wt/Hp ratio at this time. Quote Link to comment Share on other sites More sharing options...
richard migliori Posted July 1, 2009 Share Posted July 1, 2009 Who wants to build a car that goes slower? I thought this was called racing? You can spend money on exactly what you want or think you need.However, The class that you are describing is SU. There are no rules only safety compliances. I run a car that is generally 300 HP less than the competition. I found that, honestly, SU is the funnest, most challenging group of deversity that I have ever raced in 20 years. Two things come to mind why it is so exciting and fun! 1. I get to make my parts and experiment, and don't spend a ton of money to go slow. 2. the competition is REAL and doesn't depend on an "even playing field" what ever that is? Surprisingly, I have spent 40% less this season than I previiously did in a spec class. ( currently running in three divisions) Quote Link to comment Share on other sites More sharing options...
kbrew8991 Posted July 1, 2009 Share Posted July 1, 2009 in sprint racing I'd rather out drive someone vs out spend them... guess thats why I run the slowest class possible I can see where there *could* be a market for a ST3 class, just not sure if its there yet like Greg said Quote Link to comment Share on other sites More sharing options...

richard migliori Posted July 1, 2009 Share Posted July 1, 2009 Example of infineon: SU 6-27. Mazda Miata finishes second in SU on Saturday and third on Sunday. Here is one that the guy drove a great, consistant race and out drove some faster cars. Quote Link to comment Share on other sites More sharing options...
richard migliori Posted July 1, 2009 Share Posted July 1, 2009 Moti. Getting back to your question of a new class. I think that would be the last thing NASA would do right now is start a new class when some classes are consistanly running one or two cars throughout the season. If your current car is the slowest in the designated class, then maybe you chose a car that cannot compete within its category. Some cars as classified by NASA don't ever have a snowballs chance of winning...EVER! Those are the ones you don't campaign. Quote Link to comment Share on other sites More sharing options...
National Staff Greg G. Posted July 1, 2009 National Staff Share Posted July 1, 2009 Greg,ARE YOU SAYING THAT MY CAR CAN RUN STA? Richard http://www.pdg4.com" Richard, depending on the maximum hp on a Dynojet model dynamometer and the minimum competition weight with driver, it is possible that your car would be legal in STR1 (there is no STA). You need to calculate the Adjusted Wt/Hp ratio using the Super Touring formula to find out. Quote Link to comment Share on other sites More sharing options...
mrc24x Posted July 1, 2009 Share Posted July 1, 2009 (edited) We have a few guys in the Great Lakes Region that are running STR2 w/ their Thunder Roadsters against a Diasio. The class is still pretty new but they're having fun. STR2 should be the cheapest class for a tube frame car. Good Luck. FWIW, I would rather see fewer classes instead of adding new ones.

richard migliori Posted July 1, 2009 Share Posted July 1, 2009 Here are the numbers of my car if yo cold verify that. thanks. and then tell me how effective the car would be because I don't know much about that class or who runs it. 381 at the rear wheels 358 torque 2740 weight thanks, richard Quote Link to comment Share on other sites More sharing options...

You would most likely be in be in STR1 (STR1 = 5.5- 8.69 STR2 = 8.7 or higher).

kbrew8991 Posted July 1, 2009 Share Posted July 1, 2009 need to know type & width of tires.... as well as if it has any give-aways or take-backs for the oddball stuff like the transmission or whatever Quote Link to comment Share on other sites More sharing options...
