[Irace86.2.0]

I was searching, and I couldn't find a single dyno for someone running an Ace 150 or 250, except for RHD cars, which was 250, and it seemed to leave some of the torque dip in place.

I get that removing the torque dip is the utmost concern for NA applications, and low end torque is desirable for many people running superchargers too, especially centrifugal superchargers, but I was surprised to see nothing on the comparison between these difference overpipes. I would assume some people are doing track sessions and would want more power up top.

Does anyone have a dyno graph comparing these different overpipes? I am especially interested in any graphs comparing these overpipes with forced induction. I have a Harrop supercharger, and all I have seen are numbers and dyno graphs from the Ace350 with the Harrop/Edelbrock.

The other thing is that the Ace150 is essentially a slightly longer JDL 4-2-1, but the JDL header seems to fill the torque dips on every dyno I've seen posted, so shouldn't all the overpipes fill the torque dip?
