The original intent was a discussion about heads. My car is not strictly a drag car it's a street car I like to take to the strip. I don't even think most people responding to this are reading the whole thread. Seems like you are just arguing with each other and making assumptions about driving ability. As I stated before it's been down the 1/4 at one event where I made maybe 9 passes. The track we had in town shut down but I raced there for 4 seasons and made 150 or more passes on a 330' track. Even though it's a short track you still get to practice launches. That was before I got radial drag slicks and nitrous. Now I am hoping to get a bit more power out of it. I am aware that I can get my 60' better but rather than starting to high and breaking things and working down to the right launch rpm I am starting low and working my way up. This season is coming up soon and hopefully I'll get to the track 3 or 4 times. I haven't started slipping the clutch on launch yet because I need to raise the rpm more on launch before that will realistically help. At the old 330' track with bfg radials I couldn't launch more than 1800 without spinning the tires badly. So I started there and kept increasing it a little bit at a time, haven't found that upper limit of suspension or tire grip yet. Then I'll start to slip the clutch on launch. I am getting good ideas from reading some of the comments but it seems like a lot of assumptions are being made that could be cleared up if people were reading the whole thread.
