Jean, I must apolgize, I must be a very dim witted individual. I never said it was an exact science, I am merely trying to show improvement, if any, after a modification. In this case, the exhaust (Europipe II quiet). Forgive me for not calling members of NASA to make sure that the information is indisputable. If the car ran an 8.1 without the exhaust and a 7.84 with an exhaust, on the same stretch of road, in the same conditions, temp, fuel load, that's as close as I can get. In fact, I believe in this case the slope was slightly less, but negligible at best. From now on, I'll just keep the information to myself and let everyone else learn for themselves. I don't have the time or energy to justify free information.

An impact of a couple of tenths is very difficult to attribute to any modification, unless it is run consistently a few times before and after mods, on the same stretch.
I would start by overlaying both runs on top of each other on the same graph and look for shift times and long Gs during those shifts and RPMs before making any conclusions. Better still I would overlay long Gs vs. speed rather than speed vs time.
If the difference was larger, slope might not be a factor to determine this or that mod impact, but a couple of tenths is the sort of inconsistency that any of us gets during two different runs with the same exact setup.. Not saying it is not the exhaust effect, rather just that it might not be that simple.

TB, how does anyone with an AX22 know if his data is correct in regards to slope? I guess I was under the impression it could show the height. I do realize the Dbox/Pbox has some height issues although those have been resolved to my satisfaction by the tech at Vbox USA, but it is better than not having any height reference at all
How do we know ANY AX22 run is accurate. At least the Pbox can post a height line and any one viewing it can decide for themselves whether it is legit or not....

No, I really am a very friendly guy; I'll give you the shirt off my back if you need it. I just don't appreciate some of the comments and scrutiny when I'm out here doing this so we can all learn. I'm not getting paid to advertise any of this stuff; I wish someone else would try to do this crazy crap. Trying to find a flat piece of road, no cops, no traffic, and run the **** out of the car, and then pass the scrutiny test on this forum isn't worth my time, effort, risk and wear and tear on my car. I give up; I pass the baton to you all. Good luck.

I should of shifter later. I really believe that shift is the result of a slipping clutch. I bet I lost a tenth or so because of that. It's time for a new one, any suggestions? I'm still not sure if I want to go LWF or stay with the DMFW. How about some free advice for a change.

This coming from a guy who has never attempted ANYTHING in his car and provided any supporting data. Nothing, nada, zero. Take some advice Dock, do more; talk less. Dock, if you're ever in Maryland, please send me a pm, I would love to meet you, and bring your car, I've got a feeling it has never seen triple digits.

The feedback and opinions that you are being given are just like any other discussion, and to provide another point of vue simply, you are being too defensive about them, there is no reason at all. If after doing the due diligence you believe it is the exhaust impact, then that's great, could be certainly true We have all been sharing data for years here.
KPG, grow up.

Do you see any part of my post addressed to you, or to any of your specific numbers?? I was replying to TB993TT's comment made to KPG concerning the issue of determining the effects of different variables. It's that simple.
You know, I can't think of even one rational reason why anyone would ever post something like this. This is not to say I can't think of any reasons why someone would post something like this, it's just that none of them are justifiable or rational reasons...

I'll save the little blue pills for you. Actually, that may just happen sometime. I can brag about getting a new oil pump installed, new crank bearings installed, heads that were cleaned before they were installed....the things that should be done in an engine build.
