Answers vary, and since there are almost to NO as run uncorrected dyno numbers maybe we will never know. As we are talking fuel to actual HP here, not some fictional correction factor.

IMO, FI dyno runs should always be published uncorrected, as we all know the correction factor is for NA engines... right?

Bout what my SeatofthePants dyno said between all the air filters combos that I ever tested...



Now to your fuel lobe question:

Everyone advertises 32% or 38% fuel lobe FLOW where as lingenfelter Advertises 8.2mm LIFT.

stock is 5.99 or 6.0mm depending on source doc.

One of first and probably the most used source of cam and cam blanks is comp cams and they don't say 32% increase in lift, they say"32% increase in fuel FLOW" the lift goes from 6 to 7.5 or 25%

Ligenfelter on the other hand is is listing lift of 8.2mm which is a 37 to 38% increase in lift. The list the spec for flow too, don't know how much more flow, but clearly from above flow is NOT directly related to lift, Comp cams says 25% more lift is 32% more flow. if it this scales proportionately, then 38% for lift would yield 47% ish in flow.

Nut shell the fuel lobe 32% we toss around is a comp cam FLOW spec, the actual lobe is 25%.

I would been happy with an LT4 conversion, but Pray offered me a deal on a package that I could not pass up. Since I'm pure street, the question is moot for me as I can't hook now until 3rd and even then it is a bit dicey. So the rest is academic, but it does make for an interesting discussion.

Maybe it is almost like the GN vs 5.0 days.... Really the 5.0 had some huge advantages, but the GN guys kept bringing it and it did improve both band wagons as competition always does. I'll just have the popcorn.
