Megan Header Dyno Results

wouldn't it make more sense to just buy a header that makes real power instead of trying to cover an open wound with a bandaid?

you're claiming 10hp from a pulley right?

With numbers that were inflated about 25%, the graphs only showed 2 HP and 3 ft/lb losses. Assuming peak HP numbers will drop from 105 HP to around 80 HP after the dyno is fixed, the losses will be minimal... a little more than 1 HP and about 2 ft/lbs.

I don't see that as a huge tradeoff considering...

1) This is still an N/A car, and the 2.5" diameter piping on the Megan header will probably do more for the car with forced induction.
3) After 5600 RPM I'm gaining more than what I'm losing in the rest of the powerband.

Sure, my lofty hopes got shot down a tad. Lesson learned... when dealing with low displacement econoengines, don't expect much from simple bolt-ons.

10 HP from the pulley... I'm not that dumb, haha. Judging from what I've seen from the dyno results from other cars, I think 2-3 HP is a good estimate. Considering the piece is a tad over a hundred bucks and you see that 2-3 HP from 0 to 6500 RPM, I'm happy NST decided to make it.
