Thanks for the info (0-130 34.6 sec) I've got lots of data to show 0-100 mph takes around a 1/4 mile in around 14 seconds so if the final 3/4 mile is done at an average of 120 mph then it would take another 22.5 seconds for a total of 36.5 seconds which agrees with the 34.6 sec figure. I'm a little surprised that yours was one of the few responses that understood it's an acceleration problem, not a top speed problem. I'm glad to see that the twinturbo net is alive and well and that there are lots of people still interested in the car. It's been 5 years since I last visited. If I continue with this project, I'm sure I will be here more. Thanks again.
