I made a point of capturing many data points. The 128+ mph trap speed is good data to corroborate the other numbers. Nothing more, or less. It will look good on the drag standing at 6speed though! Toby... relax, just kidding Kevin
By time, I meant ET, not trap speed. I agree that the trap speed is a better indicator....HOWEVER, (please dont' think I am disputing how good the numbers are at all!) only when you extract the launch impact!
What I mean is that if you do a 60ft in 1.9 seconds, it means you achieved a 0-60mph in about 3.15 seconds, this on its own will give you better trap speed, since you will have more "road" to accelerate from 60mph to whatever the final trap speed is. ET and trap speed are indeed interelated to a point.
The right measurement, would be to take your speed at 330ft and then your ending speed at 1320ft, and compare speed vs. distance in similarily geared cars..
I know I am pulling hair here, but if it is HP we want to calculate from a quartermile run, this is how to do it IMO.
A quick comment about the max. speed mentioned earlier.. If the engine gets to the rev limiter in 6th gear, and if you have 315s in the back, then you will reach 200mph, the problem is in hitting the rev lmiter in 6th.!

Can you share the technique for doing 0-60 in 3.15s ?
My lame attempts seem to result in rampant wheelspin and or severe tramping and a pathetic ~4s 0-60 leaving me riddled with guilt about abusing my poor drivetrain

My question about the technique was genuine, be it 3.15 or 3.6s - Standing starts are not something I have practiced and I am struggling to get below 4.
Autocar mag tested the first 408hp 993tt at 3.7s so I know how cr&p my attempts are - just after some advice

Well,the dyno is going to have to wait. I have postponed it until Mon Oct 23rd. I am sure many on this board are self-employed,as am I, and realize that there are times when work comes before pleasure. Unfortunately. something has come up that I cannot put off, and I will be out of town next week. The dyno tech was understanding, and is willing to try and fit me in before Oct23 if my schedule and his allows. Hopefully this will get done sooner rather than later. Kevin

Reading launch problems here and on 6 speed that is a universal problem - I keep wondering if anybody has any experience with traction and or launch control . Racelogic or others??

I as well as many APPRECIATE all of Kevin1's (and Kevin2's) work!!
this takes time, hell, it took me months before I figured out how to hook
up my AX-22, and then find a "Mexican Road" at the right time when it wasnt raining, etc, etc.
I am also self-employed and was "insanely busy" this summer, Oh well,
I believe the Winter is storing some power for me!
