im glad you all liked the video, roland asked me to edit it for promo 2008 Death Race, l had a great time at the race and should be doing a rally hopefully in the fall. top speed for me on a stingray was 38mph with a 36t sprocket. Boring out the intake port to match the exhuast is key for winning races. l was passing all them going uphill,while pedaling backwards, very very kewl experience.................later
