Anyone going to the B&T Dyno day/BBQ
if the gear ratio changed then the output rpm would no longer be 5250. If the torque went down then the rpm would go up and hp would still be 125. Assuming this is the same car with a simple change in gear ratio. Get a good mechanical system design book and this will all be explained.
110TQ @ 3,000 rpms =62.8HP
100TQ @ 6,000 rpms=114.2HP
As you can see the different TQ reading will equals to a different HP, which accordance to you the different gear ratio= lower tq reading...
I like to hear your opinion on this, as most of the people that know you can vouch for your car knowledge, I think we can both learn from each other...
Wow, you are like those little annoying kids crying for attention, making every single attemp.. Also I really dont know how great your reading comprehension is, but as you can see its Udumkid... ps, are you ever going to grow a pair and post what type of vehicle you drive my hoe?
you must be mad, your posting on two different SN's
i drive a short bus for fairfax county, where were you this morning did you make it to school?? only person crying here is you because your 1.6L of fury is a shit box
WOWZERS!!!

How exactly were everyone's numbers jacked up? I am assuming you are saying this because your friends Civic didn't make what you guys thought it would? I do not believe you dynoed a car that day if I am correct. Please let me know how everyone's numbers were jacked up so I can understand.
If it is what I am assuming and you are saying the dyno is wrong because your guess at the horsepower was wrong then I can do nothing for that. 99% of the time we have found that the Dynapak reads 10% less horsepower than a standard dynojet roller dyno. The dynapak is a a tool strictly for tuning and eliminates any error by attaching the hubs to the car. If my assumption is wrong and you have another reason please let me know.
The way the Dynapak gets its horsepower is far more accurate than any roller dyno out there. Horsepower numbers can change depending on how a car is strapped down or what tires are used on a roller. Dynapak eliminates any of these issues by attaching the hubs to the car.
A different FD ratio would not make the HP read higher or lower. It would throw the RPM's off but it would not change the output. The only way it would change is if the gear ratio was so far off that the car wasn't in sync with the dyno. An example of this being.... The dyno sees 7k but the car only goes to 5k because the ratio was way off. If that were the case it would show a lower HP number and you would clearly notice this mistake on the graph. I hope that makes sense, if not I will try to make it more clear.

Im sorry but you are very immature and arrogant. You think you know everything, but you wont admit when your wrong. And because your car dyno'd less than you thought, you bash the vendor and dyno. If you wanted a higher HP number from a mustang dyno, then you should have gone there to get dyno'd. Instead you say the dyno is fucked up, which makes other ppl think b&t has a bad dyno, when in reality they DON'T. Its you that is fucked up...

Ok, so lets put this as an exampleusing the hp tq equation..
if the tq is 125 at 5250 then the hp would be 124...yada,yada,yada...
but then if the torque changes due to the gear ratio(ramber you said tq changes if the fd is incorrect) for example to 115 at 5250, then the hp would be 114...wich is a 10hp loss..
