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

[IndyRon]

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

Does anyone know where I can get this catch can assembly?

[Rocket]

Interesting thread. Totally different looks - so personal preference plays a lot in the decision. I think the polished Gen 4 intake looks a bit more aggressive - but just my opinion. Performance gains would seem to be similar to a ported Gen 4 intake, minus the weight savings. I definitely need to add some type of catch can setup.

[FLATOUT]

You also have to factor in the fact that the GEN V manifold won't retain nearly as much heat on track as the ported Gen IV. Both good options, and I agree a polished Gen IV looks better but I think the Gen V offer more performance benefits.

I pieced it together myself...I'll send you some details in a PM.

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.

It would be nice to see someone test a Gen V manifold on the track. See how it holds up on the Gen 4 motor lap after lap..

I'm also running a catch can on my ACR..

Great thread, having the Gen V intake installed in Houston this weekend on my 650R ACR. We will see what she puts down soon after, maybe hit the 600 Club? We will see.

Also very interested din the cam timing vs the Gen V cam. HAs anyone already done the in depth research/leg work on this? Don't want to do the swap and me stuck in limp mode or lose low and mid HP/TQ. Rather have mid range than top end as I drive my car more on the back roads than the track.

Are you going to dyno prior to the intake?

Ive asked that a before and after dyno be run if there is an opening. Will post it with overlapping charts.

Was as talked out of doing the cam. Too much $ per HP. Waiting to see if the rumors are true about a real programmer coming out for the Gen 4. Think I'd pick up more HP with tuning abilities than a cam swap that is very similar to my current one.

BLUE LINE : Stock with K&N panel filter

GREEN LINE : Gen V intake manifold & Mopar ECU

RED LINE : Headers, no cats, and stock 2 1/2 inch catback.

I have a set of big primary headers, and a 3 1/2 inch catback on the way to overlay on this graph as well. These pulls were on the same dyno, same car, and same SAE correction factor.

Nice power Andy. Seems the biggest gains were from freeing up exhaust. Is going with the Gen V manifold really worth 8HP? Although torque jumped 20.

[ACRucrazy]

Good good stuff!

If you're only looking at peak gains maybe not but there are some bigger gains earlier in the pull that mirror that torque gain. Look at the HP gain from 4200-5300 rpm, much larger than just 8hp.

Car idles like stock, and acts no differently than when I bought it. I would like to see a ported Gen IV manifold dyno graph overlayed against the Gen V Manifold.

Good point. Now just think what kind of power you would get with a massaged set of GG heads.

That's my next call . With Greg here in Houston it shouldn't be too tough to get a set done. Big headers, big catback, and ported heads I would think I could get to 640-650 rwhp.

Andy and I differ in this regard I think. I looked into heads before and just don't think the cost justifies the gain. Most I see is around 20 rwhp over the stock heads. I'm sure you probably know more then I do about the Gen 4 heads and know that they are pretty close to the stryker design and flow pretty good. A few Gen 4's here in Houston are running after market heads and I'm not seeing any big gains.

If that is the case, then it's only because of the limitations of the tuning capability to take advantage of the better flowing air.

Shooter, Andy you guys wanna go for a drive? It's a beautiful day. I'll meet you up north.

John

Hey John you have no idea how bad I want to go driving. I am battleing a third graders illness for the third day. I have an inner ear infection and the vertigo is non stop. My iPad is spinning in circles so if my spelling is whack I apologize . Hopping to be walking and driving again in a couple days.

Rob I'll talk to Greg and see what the pricing is if I drop the heads off at his shop.

[MtnBiker]

Sorry to hear that. Get well.

John

I appreciate the offer sir. Unfortunately I don't want to risk a drive in my car until I get Morgan to replace the leaking diff seal. Sucks because it would be fun, plus I think you and I might have some "interesting" stories to swap.

Robert

[MtnBiker]

Understood. Get it taken care of.

[IndyRon]

Andy,
Great numbers. I was hoping you'd hit ~615rw with the Gen V intake and other mods but every dyno is different anyway...get that thing to the track and lets see what kind of MPH it puts down! My 1 7/8 BBG longtubes are being made now. I'm getting set #1 from Toddy. I have my Gen V intake already and am hoping to get some back to back dyno numbers on mine when the weather warms up a bit here in Indy sometime around late march, early april. I haven't decided if I'm going to run high flow cats or not yet but will be running a Corsa 3" exhaust. I'm hoping for 625rw. It's nice to see the ACR guys modding!

[FLATOUT]

Good deal Ron looking forward to your numbers. I have a set of 1 7/8 M&M's being made also with their 3 1/2 inch catback. I am thinking this might get my numbers a bit higher, but with stock heads and cam 600 rwhp is already a plus.

Do you have a dyno graph of your car SAE corrected before adding the mods? Do me a favor and find a dyno you can go to again post mods, and get a run in now. People always say they are going to do before and afters on the same dyno but they never seem to and we miss out on some good info.

I would be very interested to see your complete gain from start to finish with your boltons.

Sorry for my asking this question, but, I am not mechanically inclined or follow a lot of this as it is all Greek to me.

From what I am gathering, for most, unless your doing this at home in your garage, you would have to spend what? Say 5K to build this or more. The power gains were only 30 Hp?
Again, I am not following this and would appreciate an update. I wouldn't mind dong this to my 08 if it is worth it, But, if the gains are even 50HP, would it justify spending all that money for that mere gain when you could get yourself into a gen 5 for mere thousands more? Just asking. I understand putting colossal amounts of money into a Gen 2 and getting a car that outperforms for a lot less, but, putting money into an 08 ACR that you could sell and for a few thousand more minus the money invested with this build you could be into a gen 5 no? I know in the end its personal preference.

Great build by the way. It must make you proud and accomplished doing this yourself. Gains you a lot of respect among us for sharing I'm sure.

[ACRucrazy]

40hp and 50 foot pounds to the tire NA in this case with simple bolt ons.

How many NA gen III or II are running around with 600 to the tire for 5k?
