[QUOTE="ANGREY, post: 16120952, member: 188865"] Nearly "full bolt on" (hate that term) I've seen guys yank 500-510 on 93. That's intake, tune, longtubes and no cats. Depending on whether it's stock wheels or not, it'll pull in that range. I've seen the same with E-85 in the 520-530 rwhp range. Setting aside the CJ intake (because apples to apples he didn't use one) you're basically talking about a 35 rwhp bump (on 93) for P/P heads. Locking the phasers and plates doesn't get you more power. It just makes the tuning more simple and in fact, robs you of power at other points in the curve. So the only thing I saw that would make MORE power in his build (over other modded cars) was the P/P job. Oil Pump gears, cam sprocket, rotating components and sleeves, all that stuff is awesome, but doesn't do anything for power. Again, a lot depends on if these are SAE corrected or Standard. I've seen some pretty ridiculous dyno sheets that forgot to mention it's STD and not corrected. The only TRUE evaluation (as I said earlier) is a baseline (SAE corrected) and the after on the same dyno, with similar conditions (the whole point of SAE is to normalize the temp and DA, but it helps if one wasn't at -1000 DA and the other at +2000. Even SAE correction has limitations). There are multiple reasons for this and not just because the calibrations for the dyno are unique. The way that the car is strapped down for instance, CAN have affects on the numbers. How much the tires did or didn't slip, whether or not there was so much tension that it caused the tires to bulge as if underinflated. Whether or not the tech installed the temp sensor for the dyno near the engine or far away in good/clean/cold air, etc, etc, etc. [/QUOTE]
