Aftermarket upper intake

How many aftermarket companies are making an upper intake manifold for the 6.5? Only one I know of is Peninsular. Has anyone ran their upper and if so what do you think of it? Thanks.

That is the only one, unless you make one yourself.

I have never seen anybody complain about the peninsular unit. One good thing about it is you can turn it in either direction.
Towards the turbo or away.
 
Thanks for the reply DC. Yeah that is pretty cool you can turn it. Reason I was wondering is there's an S&B intake sytem in the forsale section and it looks like it might have a upper intake hard to tell from the pic.

I'm currently working on something like this:

GW, that's looking pretty interesting. Is that story posted on another thread?

RD400HP, I'm running the Peninsular hooked up to the Heath/SB CAI. Works great. I made the set up work with a modifcation to allow for ECM sensors w/o drilling the Upper or lower intake manifolds; Intake Spacer.

That story is intermixed with a few other projects in this thread. http://www.thetruckstop.us/forum/sh...-Mod-other-project-or-two-and-finally-the-ATT

I run one also. I was going to fab my own, but use a lower from a van. I'll find the pic and post it also.

Thank's for the pics and the reply guys.What I'm trying to do is wake my 6.5 na up a little. It has the old style air cleaner on it like a gas motor. I thought if I got a F manifold and a Peninsular upper I could make it breath a little better. And then I could raise my fuel filter up a bit to make it easier to install the fuel lines which I couldn't do before because of the air cleaner was in the way, thanks again guys.

Two things come to mind if you want to wake it up some. First would porting/polishing and gasket matching. This will enlarge the passages to improove air flow. The second is alot more involved. Deck the block. If you shave a thousands off the block it will increase your compression ratio and that will really boost power. My former brother-in-law owns a machine shop and decked a block for a customer (due to it being out of square) and it wasnt much, but the power jump was pretty good. No info if the engine survived, but the customer was ranting and raving about how much more power it had.
 
I bought a intake off a 1 ton and checked it with my intake gaskets and it looks like the gaskets are plenty big enough so I won't have to do any cutting, thanks Scott.

Large turbo will wake it up. Otherwise you really are not going to feel it wake up as it was made for economy at around 150 HP tops. Turbo factory is 200 HP and aftermarket ATT is you can feel it over 200 HP. The round air cleaner intake really isn't a restriction NA...

What I'm basicly trying to do WW is get rid of the air cleaner so I can raise the FFM up so its easier to hook up the fuel lines and I can't do that with the aircleaner sitting there. And make it breath a little easier and move the EGR valve hose and dump it into the oil fill tube.

Just throwing it out there, but I believe what decking the block did was effectively raise the compression ratio to around 24:1 (just guessing here) but it's higher than stock, causing the jump in noticeable power.

Put the FFM on the inner fender or elsewhere.

Thought about doing that but then I'd be messing with the electrical harness I'd rather not. Mark

Not necessarily. Just extending the wiring for the heater and water in fuel sensors. You can splice in on those leads and leave the engine harness alone.
Use heat shrink butt splices to make the connections and you can put it anywhere out of that valley. Fender well may not have clearance for the newer Wix/Napa filters with the extended bleeder on them.

I finally moved mine up front after seeing Raceday's set up.

Where did you run your fuel lines Pav over top the fenderwell?
