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

[J TNT]

Nice Mod ! Keep us posted On my list of possible upgrades .

[ACRucrazy]

I just weighed both the stock Gen IV and Stock Gen V.

Gen V - 12.6 pounds
Gen IV - 24.4 pounds
Gen IV lower - 16.2 pounds

[DARKNHT]

I knew that would be a P90X diet between the two lol

Damn that's a bigger difference than I thought. Drove my car breifly this morning and I will be taking it by Tomball Dodge in the Morning to do a trottle position relearn and then on to work. I'll put about 120 miles on it tomorrow during the commute so hopefully the bugs are worked out lol.

So almost 12 lbs savings? Very impressive. Much more than the 7 quoted.

When are the before and after Dyno numbers coming ? I can't wait to see the difference.

We have a dyno day this Sunday. When I made the baseline pulls the car had an extensive cool down period and we made 6 pulls. On Sunday I'll get two quick pulls so we'll see how the numbers compare.

Can't wait to see the results. might consider going this route with my 08 than TT my 96 B/W. I was looking at 700Hp as my goal for either. I'm trying to put together pros and cons on going either way.

***** Morning Update***** LOL

Drove the car 30 miles into Tomball Dodge this morning to do an idle relearn, fuel adaptives, and to see what was going on with the throttle bodies.

Drive started fine enough, but about 10 miles away from the dealership I started seeing an intermitten (Z) (lightning bolt) light. It would come on in the lower rpms and around idle even though the idle seemed just fine. It progressivly got worse until it threw a check engine light and went into limp mode. I pulled over and restarted the car and all was fine. Mile down the road same thing. I eventually realized that as ling as I kept the rpms a little higher 1,500-1,800 that would keep it from going into limp mode so I could get it to the dealer.

Pulled in and discussed it with Morgan, we reflashed/relearned everything and the problem was gone. Went out and made 4 second gear pulls up to 60mph and let it coast back down. Pointed it straight and said F it. Car took off and pulled much better, much more mid range torque. It's pretty cool out so it was making more power anyway but I could tell a difference.

Drove the car another 30 miles into work and no problems. The only think I don't like right now is that there seem to be slightly less throttle response off idle than with the Gen 4 Manifold. Maybe this will change as I put more miles on it but I feel like the throttle has a little more lag than before. I'll play around with some things and see if I can get it improved a little.

So if you are doing this mod, you will most likely need the dealer to do a throttle relearn as well as reflash the adaptives before you can get everything to run properly. I'll be stuck in a bunch of traffic on the way home today so I will report back how it does in 60 miles of stop and go lol.

That is pretty much exactly why I made the gen 4 600+whp thread. Deciding what viper I want to get into next, a TT gen 2 or a full bolt on gen 4. I already owned a 06, so I don't have much interest in getting another.

DIY bolt on gen 4 (with a tune) at 650-700whp would be pretty attractive compared to a full out TT kit for an earlier model.

Exactly, so far we have seen full bolton Gen 4's trap 135mph in the quarter in good but not great DA. I think a bolton Gen 4 Viper will see 137-8 no problem. Thats a pretty user friendly drive anywhere build right there. I want a car that can make that kind of power and live for 80k-100K miles.

Thanks for the update! Can't wait to hear about the dyno, should we start taking guesses?

[SSGNRDZ_28]

Are there any GenIV throttle body upgrades / mods so long as we have to do the calibration? Or are the throttle bodies not a bottleneck?

[FLATOUT]

Not a bottle neck as far as I know. I saw some wilsons that ACRucrazy posted on the other site.

[FLATOUT]

My Dyno graph from today overlayed another Gen 4 on the dyno today. His car was stock other than Roe high flow cats, mine was stock + the Mopar ECU, Smooth tubes, K&N Filter, and Gen V intake manifold. Stock exhaust from manifolds to tip. Car is making great gains through the mid range with the manifold and ECU.

[ACRucrazy]

Good stuff! Happen to overlay it over your previous dyno by chance?
(BTW I've been checking back all day for updates! LOL)


So 570/552 with stock exhaust?! Not bad, get some headers and open up that exhaust!! 600+ hear ya come!

[FLATOUT]

Yeh I thought it might make a tad higher peak numbers based on how much faster the car felt, but after looking at what it gained under the curve I can see where it gained the most.

I think it will hit 600rwhp with headers, high flow cats, and cat back.

I'll try to get my previous dyno graph overlayed. My car stock made 4 pulls 548RWHP then 552RWHP then 562RWHP. 562 seemed like a lot that day for a stock car so I wasn't sure if he accidentally left it in STD numbers or forgot to correct them.

If I compare run 2 from stock and after manifold it is 552RWHP to 570RWHP.

[donk_316]

Jeeebus.... 20whp through out the rpm range just from a manifold swap...

Yeah I agree. G4 with full proper exhaust, mopar bandaid ECU and G5 intake manifold would over 600 at the wheels... then retime your cam the 4 degrees as mentioned by SRT and BOOM! Instant giggles.

[ACRucrazy]

Who is going to be the first to put in a Gen V cam?

Id think they would be able to email you the graph of the 552/570 overlay.

[donk_316]

Right from SRT:

The Gen V camshaft has the same exhaust profile and timings as the Gen IV cam however the intake profile has been change to improve top end breathing with a very slight loss of low and mid-range. The lifted area under the curve is greater and the intake centerline is retarded four degrees. This change alone would result in an 8 to 10 horsepower improvement compared to the gen IV profile. The cam change would be a direct swap; the intake centerline should be checked and set to 122 ATDC. Although some calibration changes were required for Gen V, our guess is that the Mopar controller would provide acceptable fuel and spark and since many of the OBD monitors are desensitized there should not be any issues with check engine lights. All bets are off with a production controller.

Its worth 8-10hp. Is it worth the hassle of a cam change though.

Yes should be easy, of course I called them 4 times about the pulls we made a week ago and never got the files.

The way I read it is that retarding the Gen IV camshaft 4 degrees would net 8-10HP...here's what Dan Lesser said about the Gen IV cam on the other forum:

I think that many people will be surprised with what just cam be done with a Gen-4 cam... both in the sound and the power department. Its no small cam already. Just some positioning adjustments alone will net some nice changes, and altering the installed centerline can change things further. Many doors open long before needing to change the cam itself. Just to give you some idea, the lobe profile of the cam in your engine is nearly identical to a Gen-4, just timed entirely differently.

Steve, thanks so much for posting that other part. I had read it and came to the same conclusion as you. Id much rather time the cam thats in the engine then go through the hassle and price of a cam change.

Sounds like besides just changing the centerline there is a "positioning adjustment" that can be done?
Looks like the stock timing of the VVT leaves a TON of room for improvement just by reading the tech stuff on the Mechadyne website

YOU could literally run an "eco" tune for cruising and switch to "all balls" mode for goofing off. You could have lumpy idle at the push of a button!

[Disturbed]

Anyone notice the company that makes the cam also has a verible lift setup. Things that make you go hummmmmm.

[Steve M]

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?
