I have enough top end for what I need...Our back straight is 200 some feet long...I get pulled by a couple buggy lengths by some guys running $300+ engines but it doesn make much difference..I make it up and then some on the infield section.I`m running a 13cb...I`m geared really really low and most everyone else is geared tall for the back straight..It works out great for me because I have a tight track and this big track that I race..The less set up changes I have to make going back and forth from each track the better
