I answered his question. I have it done on my car, and guess what, no ET difference. Dyno numbers are for tuning, showing a 6 hp gain may mean it worked, or it may not. I know that 6 hp would give you something at the track, and I have yet to see anyone gain any. I dont know how many dynos you have been around, but I have been to enough to know that a car can get on a dyno with no changes and still dyno off a few hp. It's free, so no harm in doing it, but if you are expecting some big gain, you are kidding yourself.

I've been around enough dyno's to know that a 5 hp change in back to back runs without any changes isn't unheard of. However, the gentlemen who performed the tests at ws6.com has been more carefull than most to treat the dyno as a laboratory enviornment to ensure consistent results by monitoring coolant temperature for example.
Nowhere did i say to expect some big gain. In fact I stated that there probably would NOT even be a SOTP difference. I guess i should have stated that there DEFINITLY won't be a SOTP gain, but thats IMHO, since there are people who claim to have better calibrated SOTP meters then me.
I didn't mean to attack you, but rather just give a more accurate report of the big picture. Many people are easily influenced and take statements out of context, that is especially true when there isn't any other statments complimenting a statement to give it clear meaning. The fact is that after a little more explination we agree on this subject! Maybe you should consider typing an extra sentance or two to fully explain yourself, and I'll be carefull of how I present information as well.
have a nice day

Just bear in mind that there are dyno queens out there. Cars that will put out good numbers on the dyno, but when it comes to real world testing I.E. track testing, they're a slug because of a funky TQ band or power curve. Yeah, it's nice to see some good numbers, but it's better to see those numbers backed up.

I still think the dyno is a much better way to compare gains. If your experienced at the track and take carefull notes of atmospheric conditions you can come up with DA correction factors and compare YOUR car to ITSELF. If you look at a lot of guys on here track times they aren't even consistent enough to make comparisons to their own track times. Sometimes you see poeple make posts like "headers gained me .4 ET and 2mph." What the hell was your DA on each run and more importantly your 60' which is a huge factor in determining ET.
Thats why IMHO the dyno is still the way to go.

True. I'm well aware of that. The dyno is most valuable to make a comparison of a car relative to itself. If you took a stock car and just give it 550 rwhp it won't perform close to your expectations because the suspension, weight reduction, gearing, tire, converter stall, and driver skill aren't matched to work in harmony. The car will still throw down on the dyno though because it takes most of those variables out. The 550 rwhp car relative to itself it will certainly have improved, but compared to a properly set up car with 450 rwhp it could get its *** handed to it on the track.
