Front Engine Dragsters / Learners questions...
« on: April 18, 2019, 08:08:30 AM »
Well this is my second season of racing and I continue to impress myself with an exceedingly expanding lack of knowledge. I have learned that if you want to play you gotta pay so I have spent all winter doing upgrades....including a NOS system that I am still debugging but will save those problems for another thread. I do have questions about tires and exhaust pipes though. Wideopen custom made me a set of zoomies that I love. However, after my first run on nitrous I noted that they blue up pretty good about 1/3 of the way up. Is this pretty normal when running spray? I remember back from my days of working on motorcycles blue pipes meant a fuel mixture that was too lean. I pulled the plugs and they look pretty good, not white like a lean mixture. Second, how many runs should I get out of a set of slicks? The ones I have on now have got about 6 runs on them and I do not smoke the tires excessively on burnout. Someone told me that once you begin to see vertical lines on the tires they are done. Is this true? Seems to me that I should get 15-20 runs out of a set before needing replaced. Does anyone recommend a better brand than Hoosier? Please see pics. Again thanks in advance for any input...John
