It appears a lot of folks upgrading chose the 2650 with few picking the 3.0L. Why? Is it reliability? Service? What?

2650 was released much sooner than the 3.0 so builders and tuners got used to working with them.

Whipple is more interested in Ford and Dodge and slept on the LT’s to where they are way behind on this platform. The 2.9 for LT’s also left a really bad taste in the mouth of many shop owners due to failures to where they won’t push the 3.0.

That makes sense. It's easiest to promote what's known.

So, the issues of the 2.9L have been worked out on the 3.0L? I really like the size of the bricks in the Whipple as I wish to run endurance events as well as simple street driving.

Imo a good portion of 2.9 issues were from install and/or user error. They don't like being over spun and they don't like a ton of belt tension. They are a 18,000 rpm max unit, not a 23k like an Eaton. They like the tensioner in the middle to 3/4 max. The 2.9 is closer to a Mag 2300 but with larger cooling bricks. The 2650 can be pushed a lot harder which is why it became the go to. The 3.0 is about 5 years late on this platform. But they have very good cooling and are fairly efficient. I have had a 2.9 for almost 6years with no problems. If I wanted more than 15-16psi, I would move to a 3.0. The 3.0 also makes more power at the same boost level. About 30-50whp more.

I didn’t have problems with my 2.9 either, but it was out of breath in the low-900’s. Perhaps some issues were due to install/use, but I’ve seen more failures reported on the 3.0 than I have on the 2650 across a few shop owners I talk with regularly, so maybe the same caution needs taken.

I’m still waiting to see someone push a 3.0 to the limits we know the 2650 has been, especially when ported. I’m definitely not surprised that it makes a little more at modest boost/RPM though.

[dreksnot]

So, am I to presume neither is better or worse than the other? There are nuisances with each. For someone like me who desires a reliable, safe 800-850whp without cracking open the motor for a cam or heads, either would work fine without breaking a sweat. Add supporting low side and PI fuel supply for full E85 and go! Would I need headers (w/ hi flow cats here)? Would a 103mm TB do fine? A 120mm sure sounds like less restriction but wouldn’t that make idle/cruise tuning more difficult?

Guess I do have to mention, I’d like actual 800-850whp hitting the pavement (not SAE sea level corrected) but I’m at altitude. If I dyno’d now I’d be around 460whp so there’s a nice stretch in numbers to get there. Still possible with what I’ve mentioned as to how I’d like to get there?

Both the 3.0 and 2650 can make 800-850 WHP without breaking a sweat… Headers and high flow cats will help keep the boost number down. 103mm TB is fine, nothing to be gained with a 112/120 TB at that level. Over 1K WHP is a different story though.

For some reason Whipple favors Ford over all else. I have heard through the grapevine that they are actually in bed with one another which is why Ford has gotten the latest tech first with every release. Whipple on Dodge has had lots of issues with their Gen5 3.0. They came out with the Gen6 as kind of a fix and tech update at the same time. Hasn’t been out long enough to get a real accurate review yet. The 3.8 whipple if ever offered for the GenV platform would be the heavyweight on the block for genV PD blowers. You can bolt a 3.8 on a 426 hemi and make 1,600whp without any secrets or tricks. The 2.9 Whipple on my Hellcat swapped Ram has been rock solid. I agree with King and say user error. Like most cases when it comes to performance modifications.

Agreed on the 3.8, they’re making 1500+ WHP on Coyotes too.

[ZL1Atlanta]

The 3.8 I’d be interested in. I’m convinced that is what it’ll take to beat an all out ported 2650. I just don’t think you’ll be able to safely spin the 3.0 to get there so the extra displacement at a lower RPM will be needed.

Out of curiosity, what is highest blower rpm you’re seeing out of the 3.0 so far (on any platform)?

I’ve seen 19,xxx on a 6th gen. Haven’t paid much attention to pulley combos on the others. I’ve just been watching the ET’s and all the low-8 to high-7 blower only combos elsewhere are the 3.8.

Yeah that 19K range is where I’m at. I know there’s a good bit more left in the blower but I need to move on from the DI-only kick I’ve been on if I want to fuel it.
