In my personal experience of years racing both an auto and stick..... wheel spin coming out of the hole does not have a big effect on mph provided you hook it up in 1st gear and you are able to pull through the top of 1st gear hooked-up..... but if I would spin through 1st gear and into 2nd, MPH came down very hard. Reason being, you are wasting precious acceleration feet.... the same applies for a bog, you jump out and have a bog 20 ft out for example, car actually decelerates for a moment before re-accelerating.... this is wasted track. You now have 1300 ft instead of 1320 of track to accelerate to whatever that MPH is. So that would hurt both tests if you were doing it on both. Something else that is important is crisp, clean and fast shifting.... this will effect MPH.... whenever that clutch is engaged, you are not accelerating, and the longer it is engaged, the less amount of ashpalt you have to accelerate to your MPH when you understand you were basically coasting for a percentage of the track instead of accelerating. I think Manual racing is fun and I did a lot of once upon a time.... but definitely more of a challenge. Josh, at MPH's around 120 MPH and running on ET Streets, you should have et's around 11.5-11.6 even with a manual..... 1.6x 60 fts should be the norm. I think you definitely need to slip that clutch on a 5000 rpm dump.....or in otherwords, take it up to 5000 rpm, dump the clutch 1/2 way, and slip it the rest for the next 30 ft..... do anything to avoid that bog, you'll see your 60 fts and that et rocket down if you can. A friend of mine used to have a 2002 Z06, mild mods, we got it down to a best of 11.5x @ 118 mph by doing the above. good luck ! |
