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

[FLATOUT]

I'm definitely torn on this one...ported Gen 4 intake vs. the Gen 5. I like the looks of the Gen 4, but it looks like the Gen 5 produces the same power (at least I think) that a ported Gen 4 will give you, minus the weight and heat transfer. Anyone else have plans to do this swap?

Installing one on Shooters ACR this weekend and I know a guy on the Alley bought one from ACRucrazy. I also know of another ACR owner doing the swap here in Houston.

Those were some nice gains, 570 on motor is no joke.

All of the gains (power, weight, heat) made this a must do mod for me. Hard to argue with something that has so many improvements for a reasonable price. A ported intake wasn't even on my radar. I happen to prefer the looks of this one as well. Ill have the one i bought installed as soon as I can get around to it.

Any planning to do before/after dynos?

Oh, and one more question...was the trip to the dealership more related to getting the Mopar PCM in line, or will this be a required for all Gen 5 manifold swaps regardless of whether or not a Mopar PCM was previously installed?

Well, make that two questions: is the Mopar PCM a requirement?

I'll let Andy answer about the drive he did after, but I can answer your other questions.

I did the "before" dyno about a month ago. After an hour of driving through morning traffic and a 15 min cool down..2 pulls back to back were 547, then 548 at the wheels. After a 45 min cool down, 2 pulls back to back produced 562, then 562 again. So, stock, my 09 ACR did a best of 562 rwhp SAE. It has a little over 1700 miles on it.

We are going to find out about the Mopar PCM as I want to do it without. I really don't want to drop a grand on the PCM if it doesn't need it. The Viper tech at Tomball Dodge thinks there is a good chance we will only need an "idle" re-learn. Plus, I'd really rather wait and see if Dan @Viper Specialty will have something priced reasonably enough that it is a viable alternative for us smalltime N/A guys. I'm on my 2nd Gen IV, it's not like I'm not used to the mediocre throttle response.

Hope this helped,

Robert

Next question: what's involved with the idle relearn?

I don't have a local dealership that can handle this (that I'm aware of), so if it's a requirement, that could also be a limiting factor for me...well, at least installing it myself that is.

[ACRucrazy]

As someone who has driven with and without the Mopar PCM, I though the improvement in driveability was worth it alone. Getting rid of the 02 sensor CEL, skip shift crap and any HP improvements I consider a bonus.

[FLATOUT]

I had already had the dealership do an idle relearn with the Mopar PCM. I them went home and installed the intake, and after a 5 minute drive it started throwing an idle relearn code. It got worse as I drove to the dealer, so I would say that a trip to the dealer is definetly something you will have to do, to run this manifold.

I will see what Shooters car does tomorrow but I expect the same thing.


As for the back to back dyno pulls I am interested to see what Shooters makes if we dyno it in the same manner that we dyno'ed the cars the first time. I am wondering if we leave if at the shop and make multiple pulls while it cools to see if we get that big number again (the stock numbers we saw).

We'll give you guys an update on Robs car this weekend.

Any and all info is MUCH appreciated!

So just an update. It took Andy and I about 3 hrs to do the swap. The difference between Andy's and mine is I do not have the Mopar PCM. After letting the car cool down from the drive over to the FLATOUT residence, we disconnected the battery. After the swap, reconnected the batt and fired it up. Not a hiccup or nothing. Car sounded a little throatier and idled better then stock. Had an uneventful drive to Tomball Dodge and had Morgan ( the Viper tech) look at it. He said by us disconnecting the battery, we basically did the idle relearn. So on the drive home, I brought it up to redline in 4th a couple of times...you can definitely feel the difference from around 4k to 6k. Pulls like a freight train. And the best thing is....the Mopar PCM is not a requirement for this mod to work.

I'd put that in the good news column...thanks for the update!

Looks damn good dude! So my ACRX headers are shipping out this week, time to show you how to install a set of headers on these cars

Hopefully you got a chance to drive the car again today and enjoy it. I took mine out yesterday after we installed your intake and smoked'em at 70mph on the way up to 130mph lol. Car runs good

I did a couple of 30 to 160 pulls. I can really feel the difference. Thanks for the help and install lesson.

Next for me is HF cats and a Corsa. I'll see what deals JonB has coming up.

[ACRucrazy]

I have hf cats and corsa FS. Less than 3000 miles on them.
That intake and red smooth tubes look awesome on your car.

Thanks. I think it looks great too.

Ya, I looked at your post but truthfully I'm thinking brand new, shipped to my door I can get pretty close to your price. Plus, I might be able to work a deal for my stock intake which is probably good for another $700-$750 off.

[ACRucrazy]

Oh really? Sweet. I checked around and thought hf cats added 500-700 bringing the corsa with HF cats to over $2200. Maybe I need to look again.

Jegs has HF 3" cats for less than $100 ea. shipped and NIB.

[SSGNRDZ_28]

Shooter - Looks great! Thanks for the information about the battery disconnect...

[ACRucrazy]

Yea, I was talking more the midpipe with the cats, bungs etc all welded up such as:

These from ROE for $750

And these from Parts Rack for $600

Wow! That engine bay looks great!

[Victxv10]

Looks great!! I have ported stock one currently. I may have to try this out.

Would LOVE to see a dyno comparison to a ported vs this.
Who ported yours?

[slowhatch]

Gen 5 intake looks so throwback to the gen 2s.

[Black Pearl]

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