Getting closer !! to my pb of 11.15s on $200 19" Maxxis... I have not run the old taxi for about two years and the car feels even stronger with the latest tune with a few extra little mods but I'm not keen to take it out any more and will be installing a strong standard stall in it that will make it a nicer daily driver. Hence guys here is my 2 cents worth of wisdom that might help get you guys to a lower pb... especially on street tyres. The key is to take into account and appreciate the physics behind what yoyu are trying to do. With the autos once you get off the mark and assuming that you are not breaking traction mid-track and you are shifting at the right point then the MPH and ETs should be very close on any particular night depending on the 60' time. Now based on the 100 odd passes that I have done in the taxi and some experience in a few other cars here is the trick to getting off the mark... Whatever improvement you make at the 60' mark then you will gain about 1.5 times that gain but you might loose 1 -2 mph. Note: The track gets better towards the end of the night, the dust/dirt is blown away, some extra rubber might be laid down and the air gets colder. Hence you should see traction improved off the line and power come up a little. That is my theory ... Think physics ... you can only put so much power to the ground off the mark based on how much torque the engine makes if you get it wrong te car either fries the back tyres or bogs down off the mark. Finding the right balance will get you the best 60' time. On ET Streets with 375rwkw (on a dynapack) I did a 1.53 60' launching at about 4psi. With similar power I could only get a clean take off with a max of about 1psi of boost which resilted in a best 60' of 1.78s on the Maxxis. So what do I not do? ... I do not stall it up at my target launch boost hold the car there and then just take off abruptly. The autos do not like it and you are not using the momentum of the motor and turbo to ramp up the torque. The trick is to bring up the boost slowly and as it reaches the target boost then nail it, hold the brake a fraction of a second longer and then let go of the brake. The car takes off smoother and you get to that 60' faster!! Vevapower, based on your 60' and MPH you can run a high 10s pass with your current setup and tyres but you will need to pick a good night. I hope that makes sense and you guys get some better times ... Good Luck!!
