its stays dry and the factory splash gurd is still there even when we had a flooding down here my filter was dry as could be dirty as hell but dry

91...I believe your intake was proved to you on 3800 pro as being a bad design. The Home Depot sewage line should be used for it'* intended purposes only.

You mentioned suggesting a ported rear manifold. There'* bascially nothing to port on the rear manifold. The p log needs to be skewed to work well.

actually i posted evidence about my PVC intake when we had this converstaion before i think you got what i was saying twisted i dont use the thin wall PVC i use the thick PVC intented for high pressure or what have you applications. you still havent brought me any proof or anyone else that PVC is a bad intake idea i have and there are more on the net and as far as suggesting a ported rear mani i never suggested he get one and a -log does work well when skewed so what was your point?

Alright... I'll play Moderator for a minute... let'* get this thread back on track. This is about captainmiller'* build-up.

Cap'n... any chance you have room in the budget for headers? After all the fuss I've seen about Power Logs and PEMs, I've made up my mind to hold out for headers. You get identical primary pipe diameters, and injector tuning becomes a non-issue. For this reason alone, you may want to think about some headers.

Dude, I already gave a CAI.

I think headers are a possibility down the line. The pacesetter headers seem to be the cheapest on the market right now...anybody have them?

ive seen a couple of them around ive heard of minor minor fitment issues but those were with the w-bodies a h-bodie car will be fine for the pacesetters id definanteley do the headers before anything else afterwards i assume your going to mess with the supercharger id just save and invest in getting a gen 5 blower and go from there

Pacesetters have not been tried on an H-body as far as I know. Pacesetters are made down here in Phoenix, and one of their employees is in the local Grand Prix club. Echo SSEi is first in line to be test fitted for their smaller 3800 headers with either 1-5/8 or 1-1/2" primaries (I can't remember which), so whenever that happens he'll be able to report to the rest of the club. If you want the headers with 1-3/4" primaries, you can order them and be a guinea pig.

As far as the GenV blower idea... if you want to go that far, the option is there. However, there is still a lot of performance to be had in a GenIII M90, and your budget will probably dictate what you do. If you're not looking to go all-out, the GenIII will probably suffice with a pulley change. You always have the option of porting if you so desire.

To answer some of your other questions, Autolite 104s should be appropriate after the list of mods you describe. Are you running 606s or 605s right now? You may want to experiment with plugs, as you want the hottest spark possible without knock.

For a PCM, see if you can arrange a custom tune when everything is said and done. A DHP 1.0 is proven to be a solid PCM, but nothing is as good as having the computer tuned specifically for your application. An "off-the-shelf" tune will help, but will never get you spot-on like a custom tune. See what your budget allows when the time comes.
