Your abundance of knowledge on the LS platform is astounding. Any other pearls of wisdom you can share?

So far:

Some intakes are the best for some applications but not others
MSD = LOL

FAST LSXR 102mm
Peak Power: 591 hp at 6,900 rpm
Peak Torque: 505 lb-ft at 5,700 rpm
Ave HP (3,000–7,000): 450.0 hp
Ave TQ (3,000–7,000): 468.4 lb-ft
TQ at 4,000 RPM: 466.4 lb-ft

MSD Atomic Airforce
Peak Power: 592 hp at 7,100 rpm
Peak Torque: 493 lb-ft at 5,400 rpm
Ave HP (3,000–7,000): 442.4 hp
Ave TQ (3,000–7,000): 460.0 lb-ft
TQ at 4,000 RPM: 454.7 lb-ft

FAST LSXRT 102mm
Peak Power: 592 hp at 7,000 rpm
Peak Torque: 502 lb-ft at 5,700 rpm
Ave HP (3,000–7,000): 447.8 hp
Ave TQ (3,000–7,000): 466.0 lb-ft
TQ at 4,000 RPM: 464.3 lb-ft

Looks like the Fast LSXR smokes the MSD in area under the curve and only gives up a negligible 1hp at peak and
The Fast LSXRT ties the MSD at peak and bests it in area under the curve almost as bad as the LSXR.
I'm not going to write "LOL", but I am struggling to find how the MSD is the best.

Were these dyno #'s on the same motor and same dyno? (ie taking variables out) Assuming yes, 7/8hp, 6/8tq on the avg power would not really tell me smoked. (~1%) Any quarter mile times you are aware of? A 10* change in temp or humidity could account for a <10HP/TQ difference as could dyno variability. (ie run the same set up for 3 pulls and you will get 3 different results) I don't really care about peak numbers on the dyno since you spend so little time at 7k.

Numbers appear to come from a HotRod.com article from some years ago:

I've literally just been copy pasting from the hotrod article that was posted already lol. Why are you talking about peak? I was specifically highlighting area under the curve.... i.e. the average torque figures....

I've been following this thread for a long time. It is the mother load of intake manifold information for LS engines.

Where did I talk about peak other than it does not really matter what the peak number is? The genesis of my question was do you consider a 7.6 avg hp gain and 8.4 avg tq gain smoked???
