Cut transmission 1 to 5 , 35mm pj carbs , cool head with 19cc domes to fit 4mil , 792 66mm pistons dune cut porting in the cylinders. WILL AN 18x10x8 HOOSIER JR DRAG SLICK BE TOO SMALL ? Or what would you recommend? Quote Link to comment Share on other sites More sharing options...
Toybreaker Posted May 19, 2020 Report Share Posted May 19, 2020 18" diameter is tiny, smaller tire = more rpms..... you will top out at what? 80 mph? doing 300 ft? 1/8 mile? Quote Link to comment Share on other sites More sharing options...

Toybreaker Posted May 19, 2020 Report Share Posted May 19, 2020 definitely too small. kenda K547 or quarter midget tires are a better option. get your diameter (rollout) up, can get a higher top speed and not be on the rev limiter by 300 feet....

JasonBourne.Qc Posted May 19, 2020 Report Share Posted May 19, 2020 18" and 19" slicks are what we run on the 1/8. Longer than that, American Racer is better. You could also play with your gearing. We run 18-19 front sprocket and small rear (36-37-38). If your motor can pull a 19 front, play with the rear one because it's faster to change it. Bigger front sprocket does put less stress on the output shaft, so it's a win/win. 1 Quote Link to comment Share on other sites More sharing options...
