Dyno Sheet - HP and Torque Question

[fastd]

Native1,
Can you go into a little more detail regarding the pleats on the top air filter? Did you say you picked up 9 hp just by adding the pleated top?

I wish more people would provide the kind of data that you are providing; i.e. one specific change resulted in X hp and Y torque on the dyno. I am actually changing my exhaust and moving from a Holley 750 cfm with vacuum secondaries to a 600 cfm double pumper. I will post my dyno results in a day or two on a different thread (look for a thread titled "A little more horsepower").

The first dyno sheet pic was back to back pulls. Just a swap in air filter. You will notice this filter made a little HP (9) at the very top end. I still dont like the way it looks compared to the roush filter though.

The dyno tag on my 427 srtw said 510 hp and 528 tq from roush. After all the modifications the RWHP is a consistent 460+ and RWTQ is 440+. Pulls like freight train all the way to 6500 rpm.

I believe that the carb and side pipes were the biggest improvement in overall HP gains. Many carb "experts" have told me that fords like alot of carb cfm compared to the chevys. I am very happy with the 950 cfm carb...
I see 351's with 950 cfm carbs a the drag srip all the time. So a 427 has no problem swallowing all that air.

BTW. The car is very "streatable"... Here is the air filter.
