Default 300 to 320 WHP?

Ok I would like to get to this in my 01 SSEi. I have been purchasing misc. products and most of them will not add HP. Most of them have been maint. items. However I would rather not have to change my cam at this point, I am looking more for bolt ons that would help me achive my goal. If I am in wonderland please let me know what I can do to get as close to my goal as possible.

well first of all you dont have 300WHP, most 3800 SC dyno about 190-200 at the wheel..so that is about 230-240 crank

you should do:
PCM
pulley
intake
1.9 rockers
Ls6 springs
OR pushrods
either PEM'* or headers
3"DP
highflow cat

that should give you a good start

Rogue will chime in too

Most L67'* dyno higher than stock. He'* probably sitting on 250 crank, and I think the 300-320 is his Goal. A pulley with mild supporting mods should gain you around 25hp, which gets you half way there.

When you say intake, are you talking CAI, FWI, or Manifold?

cold air intake or fender well intake. they both help performance.

Thats correct Will. So what would you consider as mild supporting mods. Is the list above concidered mild? Rockers, OR push rods seems a bit more than mild.

go to www.intense-racing.com and click 'Performance Packages' on the left-hand side of the screen. that should give you a better idea on what route you'd want to go.

I've purchased a couple of items from them already. However I am trying to get more of an idea on requirements. I would rather not just buy a package but purchase by item. So I can pick and choose what I want to goto first.

Thanks though, I have looked at those packages. I go to there site at least 2 or 3 times a week.

For the Pulley, do a 180 thermostat, CAI or FWI, and a high-flow cat. Going to an INTENSE standard PCM at the same time would be good. With a pulley on the SC and these mild mods, you should be in the 25-30 gain range for hp, and perhaps 40 ft/lbs of torque.
