Should get them installed this weekend. Got the 044 bosch inline pump installed last weekend and its working great. Got my AFR dipping into low 11's even in upper RPMs and 6+lbs of boost now. Here are some pics of the installed pump and the headers...

Looks good!....but I do have one question, do you drive your truck? You must live in a state that doesn't salt their roads in the winter. That is like "factory clean" under there.

Nice....looking good. So you keeping the chrager on then? No Raylar?

Let me know on those headers as your my guinea pig as thats what Ive been waiting on....lol

LOL...no its not a daily driver...its been in the rain about 6 times since I bought it and they were all accidents. Never in the snow even though i live in Maryland. Creeping close to 30K miles now too.......:)

Charger is staying on and I am still planning to go with the Raylar stuff...at least the heads and CAM for now....not really sure about the intake as it would mess up my whole induction tubing and intercooler mounting locations.

Trailer Queen :D

Now answer my PM...lol.

Now answer my PM...lol.

LOL...never been on a trailer either. I answered....check it!

looking good! im also interested to see how those headers work! and the bosch inline pump? would that help out power on a almost stock 496?

More for the chrager. Making more boost you need more gas.

got ya, i figured it was for the charger. so i take itd be a waste to put on a N/A 496?

Yeah, I doubt your running out of fuel with the stock pump. I was doing fine on the stock pump up to about 390 RWHP. Doubt the inline would do you any good yet.

i heard FASS fuel pumps has a pump for the 496. gota look into it though. but ill only put any kind of high-flow pump if i ever get the raylar kit and some other toys on mine.

ChevyHD, where did you get that badge ...496 allison, thats sweet i would like to get one

custom shop here in my home town. saw something similar somwhere on the net and had em made.

hey whippled, by the way what primary tube size did you go with on the stainless LTs?

2" primaries....3" collectors.

how big are the exhaust ports on the 496 heads? height and width if you know. thanks

Well, judging by the look of them when I had the exhaust manifolds off today.....I would say 1-3/4" wide x 1-3/8" tall. They are sort of shaped like the letter "D" with the flad part laying horizontal on the bottom. Sort of like how a tunnel looks driving into it. The real question is what do the Raylar exhaust ports look like......website doesnt show them.

I got the drivers side installed today....should have the passenger side done tomorrow. I will post up some PICs tomorrow.

cool. so why did you go with the 2" primaries then? i thought generally you try to match the primaries with the exhaust ports. or am i wrong??

Well they are clearly larger.....leave it to TieRod to save the day.

wow tierod! thanx, havent heard any replies from u n awhile

I got the passenger side finished up today and everything worked out really well. The passenger side was definately easier than the drivers side. No broken bolts and no clearance issues, so I am happy. I started it up after I was all done to make sure there were no problems and no codes. DAMN it was loud!! I let it run up to temp and got no codes or anything that would indicate a problem. Looks like Tuesday I will run it up to the exhaust shop and get the pipes installed. A few things I had to modify were:

-extend one of my O2 harnesses to reach the new header bung
-remove the dipstick tube to get the passenger side header in
-loosen the passenger side shock bolt low enough to get the header through the wheelwell
....everything else was pretty straight forward.

Here are some PICs of parts of the install. Its a little tough to see things but you get the idea.....

lookin good! keep us posted!

U see it it being even a more PITA to change the oil filter now with those on?

Is that strap holding your LCA in place? :D

When u started it...you have just open headers or pipes temp on?

No, looks like about the same as far as oil changes...not really any tighter there.

LOL...strap is holding the existing exhaust pipe back from the header collector. My initial thoughts were to try and hook the existing pipes up to the headers once I got them installed......I realized quickly that was going to be to much of a PITA considering i would be going up for a custom exhaust setup in a few days anyway.

Open headers only...no pipes hooked up.....and i was loud!!! LOL.

Its finished and all i can say is DAMN!! This sucker runs and sounds fantastic! I can definately tell a difference in the way it pulls up top and the way it accelerates. Feels very smooth with nice consistant power all the way through the RPM range. The sound at idle has a nice mild rumble and cruising has a nice deep tone. When you are getting on it WOT...it has a very throaty sound but not overly aggressive at all. There is absolutely no resonating in the cab at all through the entire RPM range either.....which is something I was worried about. I decided once I got there that i did not like the turn downs so we went with some slightly angled pipes in 304 polished stainless right out the passenger side. You dont even notice the CATs unless you are looking for them they blend into the pipe so well. Here are some PICs of everything complete....enjoy....

Why did you put a muffler where the turbo goes!!! LOL
Looks good! Did you lose any boost? Does the tune need to be adjusted now?

Damn...LOL...you know what? I did not even look at the boost gauge when i was flooring it...LOL. Seat of the pants says I didnt loose a darn thing as far as power goes...now whether or not I lost any boost is another question. I can check this week end when i I have more time to play around. I would assume since its breathing 40% better....a little tuning of the VE table is in order now. I also plan to take care of that this weekend as well.

So power wise what would you say? Worth the price tag?

Say goodbye to your shock boot...been there done that. Thats why I have no tail pipes now and thanks to rust...yea I drive mine on rainy days :D

Another thing, whats your thought on adding a meth kit to the truck?

Bad angle there in that PIC....its not as close to the shock as you may think. As far as power goes its tough to tell because the curve feels different now. I would say it definately picked up some HP......after I do some tuning and get a few miles under my belt i can tell more. It just feels so much smoother up top 3500+ RPM.....I used to be able to tell where the power was falling off, now it just seems to keep pulling.

Another thing, whats your thought on adding a meth kit to the truck?

I dont think I have enough boost to justify Meth yet. 6lbs-7lbs max boost doesnt seem like enough Boost for meth i dont think.

Very nice! For the entire setup,can you give any rough estimates on the cost?I'm interested in knowing if you lost any boost? I would think you would lose a little.

Entire setup including headers and custom exhaust, muffler, and CATs ran me about $2k. I will know this weekend how much boost was lost....I can tell you there feels like a pretty nice SOTP gain in power though.

Daaaaamn! For $2K Id save and get some heads or a cam!

Daaaaamn! For $2K Id save and get some heads or a cam!

Cant make everyone happy.

I think thats pretty good considering the headers were like $750 + custom mandrel bent dual 3" exhaust + muffler + 2 CATs

But what Im saying though for us non forced injected people do you think you got enuff power to justify spending that or would you suggest adding heads and/or cam for slightly more and gain more power?

RELAX! Im not bashing your decision. I like seeing people doing shit to these motors as its pretty non existent and especially since they dont make em anymore it helps others decide what they want to do. :hug: :p:

No. no biggie...thats not how I meant it, just saying everyone has their own ways of getting where they want to be. My goal with this truck is to get it as fast as I can and keep it as reliable as possible. For me, that meant not tearing into the engine. Hell, I still take this truck camping all the time. So i added the blower and all the other stuff and knocked 4 seconds (maybe more now) off my 1/4 mile time. I am still considering heads and CAM, but that will inevitably mean upgrading the tranny too. At that point i will have to look into another truck for my reliable camping vehicle most likely.

Was it worth the money? Right now I would say yes because I am still drooling over the sound and look of the setup. Once I get time to get the tune dialed in and drive it some more...I hope it feels even more worth it. From just the one ride home with no tuning for the new exhaust....it felt really good.....much healthier than it used to feel post 3500 RPM.

I dont think I have enough boost to justify Meth yet. 6lbs-7lbs max boost doesnt seem like enough Boost for meth i dont think.

Well unless your AIT are under ambient temperature. I think it would eliminate the use of race gas. Maybe you could add a deg of timing. Just a thought! :D

Yea, maybe. AITs run about 25* above ambient most of the time. I never use race gas unless I go to the track....then i use 3 gallons mixed with 10 gallons of 93 octane. This thing runs at 15.3* of timing @ 6.5lbs of boost. I occasionally get a degree of KR, but most of the time its knock free.

Damn wouldnt that be nice. I cant get under4-5* KR. How you tune it out? My AIT are also around 117* when its maybe 75-80* outside.

Damn wouldnt that be nice. I cant get under4-5* KR. How you tune it out?

Lots of timing adjustments and VE tuning. Got to get that VE table spot on!

Well lucky you as I dont have VE ;)

Well lucky you as I dont have VE ;)

If you dont have a VE table...your truck ain't gonna start :)

See how retarded I am on this now? :D

I meant I didnt have that other table you told me about other day for the WB O2 sensor. Or maybe I mis-understood what you were saying. Im retarded when it comes to tuning as my A D D tends to override sitting down and figuring all those numbers out. Thanks God for Nick huh? Lol. I CAN however gain interest if someone knew how to lower my KR to oh say 0 or where to start.

You need to get a good tuner to do some AutoVe'ing on your truck. It will cost you a few hundred bucks, but unless your interested in learning how to tune...thats the best thing you can do to eliminate your KR.

I got a good tuner. PM me on exactly how that works again. I deleted it...my bad.

Who do you use?

At least I'm not the only one that has this problem!!! LOL :o:

I wanted to give an update on the tuning side of things here. Got the WBO2 hooked back up and went cruising today. First thing i noticed is the headers made my AFR pretty lean. I had it dialed in to 14.6 with about a 1% swing before the LTs went on. New AFR after headers and before tuning was around 15.4-15.6. It makes sense i suppose now that I have more air flowing through the pipes. I did a few hours of AutoVE'ing and got the AFR back where it should be. BoostVE is still a little rich (10.90 - 11.25) because I pulled that whole table down a few percent not knowing how the headers were going to effect it.

Now here is the really odd part of what i noticed. I lost absolutely no boost at all!! I dont understand it. I am still between 140-144kPa at WOT and if anything....it seems more consistant. I know its breathing better as seen by the lean readings before tuning....but it hasen't effected the manifold pressure at all http://www.performancetrucks.net/forums/images/smilies/hmm.gif. This leads me to think there is something else with this setup that has me governed at the 6-7psi level and I dont know what it is. Thats another topic though. As for the truck....running great! Feels great! Can't wait to see if it picked up any time at the track next month

I got a good tuner. PM me on exactly how that works again. I deleted it...my bad.

Who do you use?

Your tuner should know exactly how to AutoVE your truck...its one of the first things thats done when begining to tune a vehicle. If he doesnt know how....slowly back away while smiling and tell him you will be right back.....THEN RUN AWAY! VE tuning gives you a good base to start with before tuning the timing, MAF, and other stuff before returning back to closed loop. I will find a good write up on it that will explain it better than I can and post it up. Either that or you could head over to PT.net and read about it all day long :). As far as my truck is concerned....I have EFILive and do all my own tuning.

Dude your awesome. Im sure Nick used auto VE then. Maybe I just dont know. Like I said I get the jist of things but not really the details. Im trying though. If you could PM that info or post it that would be great.

I did however load another tune that Ive had for awhile today and DAAAAAMN I can tell a difference. It had a few seemingly minor changes to it but its sick off the line now. Logged it and seems better but still pulling that 5* out around 4100-4200 rpm. It was 12.6 AFR at that moment when it pulled it out so would I be wrong if I assumed that was the problem? Running too lean or what? Suggestions. I got the log just dont know how to post the damn thing here as it doesnt support the format.
