on pump gas no meth?

 

I doubt it. With meth, maybe....

 

How do you know it's the highest HP one in the country?

 

I see. You didn't say another guy. You just said "he". None the less, spinning off the line will affect ET but isn't going to make much of a difference as far as trap.

 

+100

 

for people who dont drag that often, dyno numbers are nice to know..... not everything can be told by a drag run..... so many variables in play.

such as running an 11.9 with cams meth and bolts ons

 

Yes, but trap speed is a reflection of REAL WORLD horsepower

 

is it ? i've trapped the same night 119.7 and i ran an 11.8 at 116. I realize you can calculate a rough HP by 1/4 mile traps, but that too is a direct reflection of the driver. i can trap my car at 120, give it to you and only trap it at 115, which if im not mistaken is a pretty decent HP difference. I know all dyno's are not equal, even the same manufacturer arent equal either, just making the point that trap speeds are about as telling as 1/4 mile times and dyno numbers. They are all ball park figures

 

If your traps are varied that much then something is going on with the car (heat soak, pulled timing, whatever). I've never seen traps vary that much between pulls on the same night. Maybe 1-2mph is the norm. Nobody said it's perfect. It shows what the car is TRULY capable of though. Take a car that dyno'd 350 and traps 117. Then take a car that dyno'd 380 but only traps 114. Who's your money going to be on running the cars againts each other from a roll? (evening out driver error). Mine's going on the higher trap.

 

again a lot of variables, tire pressure, tune could be setup different, different setups. nothing was wrong with the car that night, it was running strong, both of those runs were done within an hour of each other, the highest trap coming earlier, reason being, i didnt launch, i rolled it off the line and hauled ***. decreased my et, but gave me more of a run in first gear i guess and a longer distance with traction.

if we were to race a car that is even in everyway, from a roll, higher et vs higher 1/4, then they probably arent even .... the driver mod is still involved. shift points make a world of difference as well. i do see your point, just as im sure you see mine.... ideally, higher trap = higher power, but the driver is always the world of difference

 

There will always be variables. I guess we'll agree to disagree. For me, I use the dyno as a tuning tool. Nothing more. I'll use the track as my gauge as to what the car will do on the real world. Everyone has there own thing.

 

Not trying to flame but for everyone's info and clearing confusion, dynopack reads very high numbers. I don't know the exact formula but I know on stock S2000s, they tend to read numbers that are between manufacturer's claimed crank hp and dynojet numbers. A generalized example that has been close to what people have been getting:
Stock claimed s2000 crank hp - 240
dynopack - 225
dynojet - 210
mustang/dyno dynamics - 190-195

 

the awd dynapacks i believe read differnt then what you are claiming...

 

no need to disagree, i agree totally .... just that variables are what they are.... and trap speeds just like dyno's are tuning tools as well. just one for sure is what you are putting to the ground, we will just say this, trap speeds are what you are putting to the ground while YOU drive. Dyno numbers are just a ball park figure of what your car puts down while everyone drives it, neither of the 2 being the absolute correct answer

 

It always bothers me when people start to complain about dynos reading too high or too low....who the heck knows which one is right? Just because it reads "high" relative to other dynos doesn't make it any worse or any better. A dyno is a tool...nothing more. All people should care about are gains on the same type of dyno. Heck, even the same type of dyno might read differently at different shops. Nick what did you put down on this dyno before? Bishop Motorsports FTMFW
