And now you showed that we do.......
Thanks for posting that.

So, our gain @ 5500 RPM is app. 20HP____What is our torque gain @ the RPM he is using for his gain ?


BTW...Was that dyno of your MRT #1 or #2 system ?
Did you do a dyno of the two systems, if so what was it torque & HP difference ?

Thing is there are way to many variables to say the Flowmaster seen more gains... Just repositioning a car on the dyno can really affect the numbers. SAE correction tries to equalize things for changes in the weather but it's not perfect... During my 100% stock baseline dyno session my HP # varied from 241 to 248.... All of my comparison dyno sheets use the 248 run but I could have easily picked the 241 sheet to show more of gain...

So really dyno numbers are just a good ballpark number... I know that dyno numbers are not precise... they give me a good idea if a mod is helping... I then head to the track to see if I can see an improvement there! So dyno tested and track proven! LOL!

Ok... here's the Ver 1.0 vs 2.0 dyno sheet... Ver 2.0 actually shows that it made MORE HP/TQ than ver 1.0!




Now I don't think Ver 2.0 made more than Ver 1.0... I think they are basically identical when it comes to HP/TQ gain... After I dynoed Ver. 2.0 I went straight to the track and ran a 14.33 vs the 14.32 I got with Ver 1.0 (similar weather conditions...)

That is why I don't get really all that hung up on dyno numbers...

But if a manufacturer claims 20 RWHP gain, I better see SOME THING on the dyno! And then of course I head to the track and try to back it up there too! It maybe cliche but... dyno tested and track proven!
