[PICS] Gen V intake on my Gen IV ACR [PICS]

[FLATOUT]

Where can you get a good price on these Gen5 Manifolds?

Jon B gets them at a great price, I'm sure a high volume Viper dealer like Tomball can get you a competitive price also.

Some pics of the installed intake

Wow that looks great Shooter! It's also good to know about the extra power..

[commandomatt]

That looks great.

Having said that...I would like to see that intake polished with the ribs color matched to the valve covers

Polishing plastic might prove to be difficult.

Maybe I missed it so if someone could tell me the info I'd appreciate it or point me in the right direction. What was the cost of the GEN V intake? Anything special that needs to be done to install it on the car or is it a simple swap? I've heard that the bolts are different?

I'm in the same boat as Steve M I guess. I like the look of my stock intake but if the cost to have the lower portion ported is comparable to just getting a GEN V manifold instead then I may go that route.

From what I've gathered, the Gen 5 intake is around $1,000, which is about the same cost as porting a Gen 4 lower (edit: looks like Gen 4 porting prices range from about $600 to nearly $1300, depending on the vendor).

The install isn't a straight swap due to the torque limiters that have been incorporated into this intake (the metal sleeves that can be seen in some of the pics posted)...the torque limiters were put there to keep the intake from being cracked during install. The Gen 5 heads have been machined to accept these limiters, so that leaves you with two choices: machine your Gen 4 heads to also accept them, or modify the limiters by cutting them flush on an angle, essentially eliminating them at your own risk. Obviously, these guys have been very careful during their installs, but there's the slight risk that they could be over or under-tightening the intake manifold to head fasteners, which could potentially lead to leaks. If you crack the manifold, I'd assume that it wouldn't be the easiest thing to fix...it's likely made out of Nylon-66 (or something similar), so you'd either be using epoxy or some sort of plastic welding technique to fix it. Or, you'd have a very expensive paper weight.

The "correct" way to install it would be to have your heads machined. These guys have obviously had success using the intake without these limiters, so it can clearly be done a different way, but at risk.

[FLATOUT]

Yes cut the torque limiters and use a torque wrench during install. There really isn't much to it, just don't be a meathead and overtighten everything. I did the install on both Shooters, and my car and didn't have any problem.

You also have to trim/fab the EGR line as the 2013 line connects to the center of the passenger valve cover and the 2008 connects to the front of the valve cover. You have to buy the 2013 line when you buy the new manifold and then trim it to fit the 2008 mounting location.

You do need to buy a micro torque wrench though as most torque wrenchs don't read that low. Good luck guys and if anyone needs any help with the install shoot me an email.

Is the PCV inlet size smaller on the Gen 5 intake manifold? I know the Gen 4 intake takes a -10AN (5/8" ID) hose...

Not sure the actual size just buy the 2013 PCV hose/line. It connects to the center, under side of the new manifold and then you cut it so that it will slip into the rubber boot coming out of the front of the passenger side valve cover. You can see it in the pictures on both installs in this thread. Pretty simple task.

Well, I'd have to figure something else out since I'm running a catch can:

[FLATOUT]

Hey Steve ok forgot you were running that can. Only thing you would have to change is the rubber line exiting the can and connecting to the manifold. You would just have to run a longer line that would go under and to the center of the new manifold.

So you are running your PVC line back into your intake/engine?

If so, there are a lot of threads on this very subject that talk about the problems this can cause.

A catch can will eliminate this....image.jpg

I have a Gen 5 intake on the way too.
I also use BBG ported heads and intake, Mopar Race ECU, MM headers, no cats and ACRX type mufflers with 3" custom SS turnouts.

Unfortunately I haven't had the car on the dyno with these mods and the '08 ported intake.
The engine is coming out on Monday so I won't have a chance to do so.

I WILL have a dyno number and report back after the new engine install (with the above mods plus a few...) and the Gen 5 intake.
Should be about 3 weeks...

LOL yes fully aware of the blow by issue and the problem these motors have with oil contaminating the intake charge. I am switching over to a seperator shortly. I was illustrating how to install the new manifold if someone wanted to retain the stock PCV routing.

[ACRucrazy]

Would there be a benefit to running the Gen V valve covers as far as oil consumption goes?

Not sure we would have to pull a Gen V throttle body off and see if the back of the TB was coated in oil similar to the Gen IV's. They obviously changed something. The inlet for the blow by is now routed under and to the center of the manifold I would think for a more even distribution of the oil. Not sure how much of a difference it makes but I still don't want any getting in there period.

If you have ever had your manifold off you can see that the front cylinders see more of the oil than the rears. Anytime cylinders are seeing contaminants in an uneven fashion I get concerned. I just want it out of there so I don't have to worry about it when I am beating on the car.

No kidding ..... here I was thinking it was alloy.

Well goes to show you learn something every day

Looks nice with some light tire shine though

Gotcha...

Kinda' figured you knew better...

[Timnineside]

Whew what a read. I to was thinking about porting my gen 4 intake and 01SapphireBob and I have been chatting.

So what I have learned from this thread:

Gen V intake is about $1000 from JonB
Relatively easy install (3hrs and trimming mounts)
Micro Torq wrench needed
No relearn if battery is disconnected during install
Adds HP around the 20whp range
Lighter (around 12lbs)
Car runs better and pulls harder at higher RPMs
PCV line needs to be extended

Anything else? Anyone know what a stock gen 4 intake is worth ?

Looking forward to shooters after numbers (hope I didn't is them in this thread)

Great thread FLATOUT!

Oh and you can't polish plastic!

[FLATOUT]

Tim good post but I will add that my car made 30rwhp under the curve and additional 32ftlbs of torque under the curve. Peak numbers weren't indicative of the over all gain we saw on the dyno.

And the 2013 PCV line needs to be shortened to work with the 2008-2010 valve cover. If you have any questions about the install shoot me a PM.

[Shooter]

If the dyno shop is open between Xmas and New Years, I'll be able to get some #'s with the new intake. If not, it will have to wait till mid Jan.

Yeah I am going to take you up this. I think this is the route I would like to go. Did you plan to do a detailed write up? I would like to do this in my home garage and I don't have gobs of tools like I do at my shop so I would like to have everything handy and get it done at once.

Thanks again! Looking forward to the numbers Shooter!

I also would like to add I took my air box off today and found oil residue outside of the throttle bodies. I'm sure that's not a good thing. It makes me wonder if the gen V intake would reduce the chances of that and reduce the need for a catch can.

[FLATOUT]

Yes I do plan on doing a detailed write up I have all the pictures just need to organize them and get the thread up. Might have time over the holidays.

Great info , keep us posted !
