Take it to the track and get numbers that don't lie. My 5.3 put down 486rwhp consistently in 4th gear on a mustang dyno. If I want to see 500 I can just drive down the street and throw it on a dynojet.

 

That is true. Plus if you did it last thursday it wasn't the best day for dyno #'s. The DA was right around 2000.

 

Empire is open. Get over there

 

I'm not to sure why they would tell you to go with 1 3/4 headers for a blown 6.2? I have 1 7/8 on a N/A 6.2, but plan on pro charging it soon. They numbers look good. Take her to te track.

 

they said it would help the sc.
Im useing the stock ait box and the tube Magunson supplys in there kits. Im using a Amzoil EA123 Nano fiber filter.
I was wondering what caused that dip in the hp ant tq between 4000-5000rpm.
Maby I should get a muffler and ditch the stock box?

 

I don't see how it would help the super charger? Nonetheless, that's no turd. Post up track times ASAP

 

I'm running the stock airbox and tube that Lysholm supplies as well as the stock 87mm throttle body, for the longest time I ran the stock cat back too. Seriously, go take it to the track because you might be pleasantly surprised.

 

I'm willing to bet it scratches a high 12

 

What is Your IDC on the stock injectors

 

12.79 is my guess
