but also, the acutall track plays a big role. Almost all strips are slightly down hill however some are more then others. Over on a Michigan import website, all the west siders were getting amazing times but around here, most of ours were just slightly lower then stock rating. Were talking sub 15's from basicly STOCK LS's. A kid from around here went over there did a 15.6 here in his GSR, went over there and ran a 14.9 We finally figured out that Martin drag way has 3 things going for it. It is right by the water so it gets that cool air from Lake Michigan. Next, It is built that It always has a tail wind. Last thing, it has a higher slope then what is legal for (what ever the big Drag leauge is) compotions. Check that out too. Look at Dohc_accord, he says that Type R's over in colorado run consistant 16's. Over at sea level, the same car could probally do a 14.5.
