It was time to change out the air filter that was on the 05 when I bought it. Never really liked this type of air filter system.

I'm thinking QA must be a problem with the Sniper product line. I was questioned about fit when I bought a pair of Sniper valve covers. Mine are fine, but it's possible others are not. If I bought a intake manifold whether be a Sniper or other brand and it didn't fit properly I would simply return it and get a replacement or refund...

I think some of the QA issues with the Sniper is that one guy who gets one that's bad and thrashes it EVERY WHERE, I know when the Valve covers 1st came out. There was a lot of fitment issues complaints , but those post were from the same 2 people over 6 different forums , every covers I've been involved with has fit nicely , 1 had was warped ,it got sent back and holley was on it fast.
STU in that LSTech thread Keep in mind that Martin Smallwood works with CID (competition induction design) he's one of those guys who bitches about everything, same with Steve turbo....
I've had 5 of of the sniper intakes not including the ones we tested @ work in the last 2 month, 2 of the PART# 837262 both on Challengers, one was modified the front inlet was plated over and the top changed over to a flat plate with twin 4500 style carb mounting , the other was stock.
the other 3 were the cheaper 837032, 1 on a 2012 ram the others were a charger and a challenger, one of the 3 had a warped flange. and didn't line up on the p-side, sent it back, holley got us a new one in a week...that one had bad threads for the TB, sent it back and he went with a Edelbrock.

That might be trick to mount cooling coils in the plenum to circulate intercooler fluid. Would have to experiment with it to keep it from being too restrictive. Or cut the runners and insulate the plenum using rubber hoses and maybe cool the top plate externally?

Going to drive the truck around town one more time to get some spark plug readings. Been running it at 50psif and it's running ok. Still same a/f raio and rpm surging at/around 1500rpm and idle while in gear with the a/c on. But, a little better since lowering the fuel pressure. Then will pull the Ritter intake manifold to see if it can be ported & polished on number 1, 7, 2 & 8 port runners. Want to try and see if the port work will make the spark plugs look more even firing. The spark plugs that got replaced, do look to be running richer on number 1, 7, 2, & 8 off of the main coil spark plugs for those cylinders. Even though dropping the fuel pressure down has made the spark plugs look better. Those cylinders do look to be running richer. All I can do is try. If it works, cool. If not, will be installing a different intake manifold.
PS. I'm assuming that the 80lbs injectors were scaled correctly in the present tune...

The ATS trans and Copilot are working good at least. :thumb:

When the 392 was in the 03. It didn't have this problem with the spark plugs running richer on # 1, 7, 2, & 8 cylinders when running the KRC 390 tune... It did have the Ritter intake manifold on the engine with the 6.1 heads. The only difference from the 392 in the 03 to what it is now in the 05 is the stage 4 turbo cam, BBK 90mm throttle body and 80lbs injectors. The stage 4 turbo cam has also dropped the cr down to around 9:1.

Did a dead stop, roll into full throttle with 6psi boost test run while driving the truck around town today. Only up to the 65mph speed limit. At 6psi boost, the a/f ratio was 10.0. That was with the fuel pressure dropped down to 50psi with the boost port plugged into the intercooler. The fuel pressure was at 56psi @ 6psi boost. Looks like it wont need the boost port hooked up... Just wanted to make sure it didn't run lean after lowering the fuel pressure.
Actually thinking of dropping the fuel pressure down a little more just to see what it does.

Also wanted to see how fast the turbo boosted up. Didn't want it to boost up too fast. It has a steady boost up and that's what I wanted. Need to get the manual boost controller off the 03.

Did find out from HHP that the stage 4 turbo cam was developed using a ported 6.1 intake manifold.
They did say that the Holley sniper fabricated intake manifolds looks promising.

Did some more research on the Ritter intake manifold. Jason(HHP) has only seen them used on race cars. Jason has a Ritter on his race car with a single turbo. They haven't had any problems with them on a race car application. For what I want the 05 to be able to do. Looks like it will have to have a different intake manifold.

The 6.1 is the best over all intake up to about 800hp
Any more than that you should run the Ritter

in that case all you need is a stock Eagle 5.7 with a 518 behind it. that'll hit 350Hp , with a 65RFE they hit 310-325. with an A833 they hit 365.
this Week I did a 358Ci Eagle(3.9185X3.72) Stock, (I mean went to the dealer and picked them up) Eagle heads, SRT392 Non-MDS cam, Edelbrock intake, 90mmTB, made 498hp @ 6100 ,510 Tq @ 4300......that should net you about 410-450rwhp depending on trans and drive accessories
