Hey 2THEXTRM,
I see you also have that Airaid box on your 4.7.
What did you do, get rid of the "hat" and make up your own plumbing to the throttle body?
Did you notice any improvement with that Poweraid spacer?
Thanx,
John

Yeah I dumped the factory air hat and ran a rubber 90 off from TB into 4" piece of PVC into factory accordian. I will probably be replacing the accordian with one length of PVC as I have heard I should benefit with less restriction for incoming air.
The TB spacer has been reported to do nothing for 3.9/5.2/5.9 engines but mixed reports on the 4.7. I have not been able to check mpg change up or down but throttle response has been improved and my exhaust is suprisingly much deeper and throatier. If I find any improvement in mpg that will be a freebie since I am happy with what I have gotten so far anyway. Their is a noticeable whistle when first accelerating and it either goes away after about 1,500 rpm or gets drowned out by my Flowmaster, I am not sure. The sound isn't annoying enough to want to take it off with the better throttle response and better sounding exhaust though so it's staying until I upgrade to 70mm TB that you can't use TB spacer with.

Bob,
Yeah I agree with you on getting rid of that accordian, restriction city, IMO. I wish Airaid made their filter box out of composite because the metal conducts heat.
Good to hear that the spacer works for you. I'm thinking about opening up the TB with the dremel when spring gets here and maybe I'll install one when I do that mod. That 70mm sure is tempting though...
What series Flowmaster did you go with?
Was it a whole stainless cat-back kit?
single or dual exhaust?
Did you install it yourself?
How do those splitfire plugs work for you?
I had them in my Chevy p'up and the smallblock ran well with 'em.
Must have been fun changing these coiltop plugs, huh?
Have to find out the O-ring size and keep some on hand. Do you know if they lube those rings with silicone-dielectric compound?
Use never-seize on the plugs because of steel-aluminum oxidation, correct?
Do the ceramic pads stay cooler to reduce warpage of the rotors?
Sorry about picking your brain with all these questions but these mods seem to be pretty good ones in my never-ending quest to upgrade the quality of my new truck.
Thanks again,
John

Whoa, reminds of Mcaulay Caulkin asking questions to John Candy in the movie "Uncle Buck"!... After a round of questions, John Candy asks, "What's your record for most consecutive questions asked in one breath?", LOL. I enjoy answering questions that I have an answer or opinion for, I am always trying to help out in the different forums(much to my wifes dismay):)
With the body lift installed I noticed that the underhood heat has decreased, must be because there is more space for the heat to dissipate around the motor with body up higher. The powder coated frame for the CAD never really seemed to get hot or conduct heat like I would have thought, I think it is in part to not having a hood-liner, that really traps the heat into the engine compartment.
I am very happy with the peformance gained from the AirRaid, especially since it allowed the Flowmaster(my first mod) to really improve low to mid power band and the sound increase really makes me grin everytime I hit the throttle. It is a FORCE II stainless catback system(Part# 17278) with a single in/single out 40 series muffler that exits in stock location and it rocks IMO. Installed it myself, the factory exhaust is a POA to get off(same problem with my 99 RC that I added Flowmaster), you either need a torch to heat it up at the cat(beat away with a rubber mallet till your arms fall off:) or a side cutter(Preferred method) to make a 1-2" cut on each side of pipe(running length ways) to allow the pipe to slide off from cat. This whole effort is caused from DC overtightening the u-clamps so much it makes an indent all the way around pipe so deep you can't just pull it off. Once the factory exhaust is off, the Flowmaster lines up better than factory and you tighten bolts. As I recommend to avoid wasted time and smashed knuckles, the cutting method is preferred and the exhaust would still be re-usable with a small line of weld over each cut.
The splitfires work awesome, my idle is now almost perfect, no difference in mpg though. I actually cheated and paid my dealer $50 to install plugs cause I started to take out old plugs and figured I could use my time for more productive things, LOL. They do use dielectric grease and never-seize, I made sure of that by watching take the old ones out and put the Splitfires in. After watching the tech, glad I let them do it, another POA IMO:)
Guess my listing of mods is smowehat misleading in that I have everything, but it's not all installed. The powerslot/ceramic pad combo is supposed to be the best for our Daks talking with different mechanics, I actually have them sitting in my shed waiting for winter to get done with, don't like the idea of slapping on $250 worth of front brake parts in the middle of winter to break them in. I will let you know once they are in though. I have wanted to put them in since I have had the parts in my shed since before xmas. Same with my truspeed computer, that is sitting on my desk waiting for the time to put it in. Stinks working 40+ hrs/week and going to school nights/weekends for another 15+ hrs/week. I have to wait for breaks from school to do anything that takes more than a couple hours. Oh well, nicer weather and it will get dark later so I will have more usable outdoors time for installing the toys.
I know everyone has been wanting to know the results from my Truspeed so want to get that in ASAP so I can share my findings and if it was worth the $$. I suspect it will be, if it does what Superlift says they will do.
Man this has to be the longest run-on response I have posted, oh well gotta go, the wife is calling me to dinner:)

Hehehe! Uncle Buck - good movie!
Yeah, that Flowmaster SS cat-back sounds like the way to go. I got an air compressor in the garage with quick-connect plumbing out the front that I can hook up a die grinder to make quick work of the stock system. Thanks for the part #.
Yeah those plugs look tough, might be worth it to let a "Grant" go.
Good luck with the rest of your mods and thanks for answering all the "consecutive" questions! LOL
