Stage ratings for Engine Mods.??
Just an idea.
Maybe we could refer Stage ratings to our Bonne engines based on hp.
This is what I mean.
240 - 280 hp --- Stage 1 - cold air, pulley
280 - 320 hp --- Stage 2 - Stage 1 + exhaust, pulley and PCM
320 - 360 hp --- Stage 3 - Stage 2 + cam, pulley, intercooler
360 - 400 hp --- Stage 4 - Stage 3 + heads, engine work, pulley
400+ ------------ Stage 5 ...........????

I doesn't mean that we couldn't have Stage ratings for your N/A 3800 engine too.
170 - 190 hp - Stage 1
190 - 240 - Stage 2
240 - 280 - Stage 3
280 - 320 - Stage 4
320 + ----- Stage 5
That'* just a 5 second initial stab at it but you know what I mean and could probably fill in the required mods for each Stage better than I can.

ahh...like the intense website? We could do a separate techinfo article for L27 and L36. L67 already has one at the intense website (could be ZZP im not sure).
Well lets start this out:
L36
Stage 1 - 15-20 HP
-CAI
-Free flow muffler, hi-flow cat
-180 T-Stat
Stage 2 - 20-30 HP
-Rockers
-PCM
Stage 3 - ???
-Stage 1 TB from ZZP??? (don't know if the GPGT TB works for us)
Stage 4 - ???
-Maybe TOG headers or Ported Exhaust manifolds

Good Idea silver. For us 3800sc owners, i think you need to change your stage 1 info. Dosen't a 3.4 pulley add 25hp and 50tq? Just pointing out your TQ numbers are a little low.
Gotta thow headers in there too.
