No. If you re-read what he wrote:

You'll see that the 16 hp is from the header, intake, and exhaust.

ok... the 16whp they are going to be of the ZPI exhaust / MMW Intake & Cold Air Box / MMW Ignition Equalizer / MMW Engine Damper, not the header... if you add the header would be near of 30whp.

ok... no where says that the header was include in the 16whp... it says that the ZPI exhaust / MMW Intake & Cold Air Box / MMW Ignition Equalizer / MMW Engine Damper were include, but not the header.

We GAINED about 15HP and 30lbs of torque from the HEADER.

We let the owner drive the car around tonight so the ecu can learn, because the more we ran it on the dyno the more it gained Hp and Tq. On some runs the car leans out and or richens up and we loose some torque at the very low end but gain alot at starting 4500rpms. So we decided to let the ecu do it;s thing and learn.

So were going to re-dyno tommorrow.

only the header and intake of WR are making 19whp gain...



it is imposible that adding exhaust, ignition eq, engine damper, and the cold air box make less than the header and the intake together

If you look at the dyno sheet you posted that is from a dynojet roller type dyno which you will see Different hp numbers compared to the dyno which was used . A dynapak hub type dyno. Weapon-R is showing the gains from a stock header to our race header. If a dyno jet was used then the number would be different but gains will be similair. 2 different dyno's 2 different set of numbers. Also that dyno sheet shows 19hp and 9 tq. i would trade -3 hp differencein HP anyday for an additional +21 ft tq. Wouldnt you? AND rember the ECU is still learning. Stay tuned =)

I want to clarify - The preliminary dyno was of stock header with MMW intake, ZPI exhaust, et al sans header and then a second run was with the header added onto the other stuff right?

Without the rest I doubt you could just gain 16 hp on an entirely stock set up with this header. That sounds a little like doubting your work but 16 hp gain is still a huge amount. Good job guys. I'm am thoroughly impressed.

I believe ToastBox asked my question but I'm not sure.

Torque gain is amazing. No CEL is amazing. HP gain is amazing. Product is amazing.
