Fat-Tony Member 5,364 Member For: 18y 8m 11d Posted 25/04/08 11:20 AM Share Posted 25/04/08 11:20 AM (edited) Every manual I race with the auto I beat during the change. I flat shifted the arse out of my ute when I had it and couldn't even get the tyres to chirp, and on a flat change there was a moment of LAG that was pronounced during the 2nd to 3rd change. F6 ute I had the same guy tune my ute as you did and I still had this issue, perhaps your senses are just too dull to notice the lag old man Edited 25/04/08 11:20 AM by Fatsex Link to comment Share on other sites More sharing options...
youngy Member 293 Member For: 19y 2m 29d Posted 25/04/08 01:00 PM Share Posted 25/04/08 01:00 PM weve had alot of debate over this BOV issue, it wasnt clear from the people on here who have changed their BOV, or run no bov at all, whether it reduced thier lag or not?I think simon from nispro, said it was no help. I always believed that it might be but never tried it because of what ive read on here...anyone know of somone running a big BOV that has improved their lag between shifts???the top 4 manual guys use no blow off valve including myself. flat changing is the key!

groper Member 611 Member For: 17y 10m 1d Posted 26/04/08 02:25 AM Share Posted 26/04/08 02:25 AM (edited) well I blocked off the BOV and I must say, I can hardly tell the difference in lag between shifts, just a lot more tut tut tut tut tut tut tut tut tut... im betting the difference is fairly marginal.Also practiced some flat changing, scary at first, but not so hard afterall... preload the gearstick in the direction of the next gear, hold the throttle flat, stab the clutch, and straight into the next gear she goes...My 'testing' did net me a $250 speeding fine just as I was almost back at the speed limittho... thank god he didnt get me 200m further back up the road Edited 26/04/08 02:28 AM by groper Link to comment Share on other sites More sharing options...

Your clutch needs to be upto the task of flat shifting too. My stock T56 clutch loved it into 2nd and 3rd with 250rwkw's even though it would slip on boost in 4th. Youngy had a Mal Wood Opt 6, F6 UTE has a Stock F6 (AP) unit. Link to comment Share on other sites More sharing options...

The black line is the linear average.All transmissions:mphvsrwkwall.bmpZF Automatic 6 speed:mphvsrwkwA6.bmpAutomatic 4 speed:mphvsrwkwA4.bmpManual 6 speed:mphvsrwkwM6.bmpPretty interesting eh! ... The Auto 6 speed figures are the most consistent while the Manual 6 speed is all over the place.I think that this should provide a handy reference for both experienced and first time drag racers.What do you guys think?
