gen 2 intake vs gen 3?

[ARRESTmeRed04]

anyone ever see any dyno comparisons between a gen 2 intake and the gen 3? i remember a long time ago a few people saying the gen 2 was better but never saw any dyno's to back it up. it looks like the gen2 would make more lowend power to me?:dontknow: but i wonder how it'd do up top?:dontknow:

 

[VENOMOUS1 RACING]

Didn't think it would match runner and bolt hole wise? This Gen 4 deal sounds like the BOMB diggity

 

[ARRESTmeRed04]

I think the gen2 bolts up, could've sworn that guy putting a viper v10 into a durango was using gen2 heads with a gen3 manifold or vice versa. And I think I've seen a picture of an Srt ram with a gen2 manifold on it. Just been so long now I can't remember

The stock Gen II Intake manifold produces FIFTY more ft. lbs. of torque between 2800 and 4000 than the stock Gen III Intake.
A longer runner with no taper tunes harder at peak torque.
There is no increase in peak horsepower over the stock Gen III Intake.

To convert you'd need (2) TBs, proper linkage, a revision to the thermostat housing (like from a Viper car), fuel line routing, some kind of air intake system and a "custom" upper rad hose.
The Gen II also used lower capacity fuel injectors than the Gen III.

The o.e.m. Gen III Intake was a Lambo design and was more for form than function.
The Gen II is a better manifold comparing each, unmodified.

The Gen III Intake can be modified to work quite well but it takes a considerable amount of time and effort..

unless you got deep pockets boss, it really aint worth a nickle

I was thinking is keep my eyes open on eBay, never know when you can get a good deal.


Ronnie, is there any loss in peak power? And what would be better in your opinion, a ported gen 2 or ported gen3 for our trucks?

 

[Ram From Hell]

I had given that some serious thought when I built my current engine. I had ordered up a mock-up engine from Arrow Racing Engines just to try it out, in fact. In the end I opted for the cheaper solution, having Hogans build a new one.

It as Ronnie said, it bolts right up. The linkage to the twin TBs is critical, so you have to fab up something that keeps them in perfect sync with respect to blade position (no common plenum).

Between that and the extensive plumbing for supercharging with that intake, I opted to pass. Glad I did. Even though it would have looked cool, the Procharger would never have worked.

No, I haven't seen any loss in peak compared to the Gen III Intake.
The increase in TQ with the Gen II Intake during that 1200 r.p.m. window is pretty dramatic; not all that different than the ram intake manifolds used on the old Chrysler letter-series cars. Those old ram manifolds also worked in a specific r.p.m. range- In their case from 50 to 80 m.p.h. for passing and general mayhem

So, "It Depends".. to answer your question about which Intake Manifold is "better".

Mods we're doing on the Gen IIIs are producing great results so I stopped looking into the Gen IIs. The improvements are ALL in the top-end with the Gen IIIs so if you're after more low to mid-range torque you'll have to find it in other areas.

There are quite a few gen2 intakes around (due to the Roe s/c) and there will be more when Roe has the new supercharger ready. Remember that the fuel rails are internal on a gen2 so you will need side feed injectors or billet fuel rails for top feed injectors. I'm not sure that your fuel rails would line up correct but could check that if need be...I have truck rails and a gen2 intake laying in the garage.

BTW, I have gen3 heads, gen2 block and gen2 intake.....everything lines up fine. Initially the gen3 heads and Roe s/c then the gen2 intake on when the turbos went on.

$600 for 50ft-ibs seems like a steal to me. Wish I was closer to you, I would be very tempted to try this.

now why did you go and post that, i might have to hold off on the billet clutch master and slave cylinders now.....wonder how hard it'd really be since all the wiring and throttle linkage is on there. and how much injectors would cost?

 

[caveman]

Tempting, isn't it? I say do it and let me know how it goes.

wouldn't really be able to tell you since i can't powershift my truck right now because of a faulty slave cylinder

 

[RAMDUDE]

50 lbs extra of TQ is alot. seems something to look into.

 

[ARRESTmeRed04]

Hmmm looks like someone already bought it....:itsme:

Wonder who it could've been?:dontknow:

 

[caveman]

Don't look at me. It is extremely tempting, but I don't know enough about the conversion to feel comfortable yet.

So if you wanted to do this swap, besides the throttle linkage, throttle bodies, what exactly do you need to do for the fuel plumbing? Is there a limit on how much power you can make based on the built in fuel rail design or will it support a lot of power as well (i.e. 800whp+)? I think it would be easy enough to plumb up a 2 into 1 split intake system if you wanted to add forced induction later on down the road (turbo or centri) but again, I know guys that are good at that stuff. Also, has anyone that has done this swap actually dyno'd and documented back to back results?

If one stuck with the Gen III intake, what mods are people doing to get more power out of it? If I am going to pull the one off the engine going into the van to polish and/or paint it, I may as well do some tinkering at that time I would think. Thanks for any info!

 

[ARRESTmeRed04]

Not sure on the power limitations, from what I've read the internal fuel rail is 1/2". Roe racing sells an external fuel rail kit for about 500 bucks, but you would need new injectors with it too. The factory fuel line hooks up on the passenger side rear of the gen 2 intake. The TPS was on the wrong side of the gen 2 intake but I was able to just put it on the other side. I'm still thinkin on the throttle linkage, and tryin to find out if the factory gen 2 injectors can feed a gen 3 engine or not

 

[FATJACK]

You guys need to listen to Stinker. You are about to piss away a ton of money.

 

[yellowfever#154]

Jack is right, put your $ into porting the gen III with either Ron or Tony. The troubles of making the dual throttle bodies work will be a pain in the ars.
