R7 380 vs 430 - any hands on?

[AsLan7]

380 vs. 430..blah, blah, blah..
As the Dire Straits song goes, “money for nuthin’“..

If a person is going to spend a rip off amount of 11K+ for an ECU made 50 horses to make a 430..for what amounts to being no difference in engines at all, I personally would spend twice that for a set of 350s or 380s...
Now, we are talking about a power difference someone will notice.

Then, I would have the horses to add a Captains Call!

Hey t
You are still planning on asking about this at one of the manufacturer shows, correct??

I’m with ya. I just don’t see any internal differences listed anywhere between the 380 & 430 HP for the new 2017 6.2 liter Volvo Penta engines. I (like you) believe it’s an ECU software upgrade only—for $8-10k more!!

To bad we couldn't get some ecu's from some of the irma totals.

The engines are confirmed to be exactly the same. Same internals, heads, pistons, compression, everything. SMH to think an 11K upgrade for basically nothing except a tuning tweak and different props that yield slower plane times.

I’m hoping to go to the Toronto show, but I’m not 100% sure yet.

I'm pretty sure as GM 6.2 and 6.0 have different cam profiles and mods done .The marine versions should be similar... Your not essentially detuning a 430 hp motor to be less efficient to 380 hp..
Has to be more than just a remapped ECU..


My Escalade uses the same 6.2 VVT 403hp that the GM Yukon used 6.2 vvt 365 hp . Different cam. Compression. Ecm.

Noticeable idle differences too..

Take a merc 496 mag..vs 496 mag HO.. totally different idle from cam profile and component s.
Same with Volvo 8.1 GI vs GXI..

I may be wrong on the new marine versions of small blocks.. but that would just be mean to have them de tuned for a discount via ecu..

6.2l. Same exact engine Matt. Confirmed from everyone I’ve talked to at VP USA.
The old 6.0L engines 380/430 were different
The 6.0L ran 9.5: 1. The 6.2L engine’s run 11.5:1, making horsepower much easier to make.

To quote you above, I think they r being mean, Matt—or maybe deceptive/sneaky/ exploiting is a better word.

All the VP engines prior to the 2017 6.2 Volvo Penta’s have the internal changes as well to boost HP.

Now that VP was able to squeak out 430hp from a small block (quite a feat btw leaving the heavier Merc Big blocks in the dust), I think they just detuned the 430 horse to 380 to fit a HP niche and charge for the extra—in other words, $8-10k for a software flash!

Please say it ain’t so!

The Mercs have a fixed cam. Very archaic compared to the Volvo. The new VP’s have the ability to tune cam timing into the mix, (VVT) which would allow more fine tuning the upper RPM range.l 11K basically 3-4 MPH and less hole shot?

Again, double the upgrade premium and add another engine. Now I’m impressed.

Matt I've had both of those 8.1 's
Yes there is a huge diff at idle and off and performance. But I would like to change the props on the gi to the f6 the gxi has and see what it does. See if it hits the rev limiter.

The vvt in a merc isn't too far away.

Geeze.. that would be a captains call deal killer.. id miss the rumpta boggaty idle..

Figures technology takes over.. yep mean!!

Since they all depend on GM, It will be the end of the big block as well.

[AsLan7]

Exactly.
BbP will now be Sbp.

Except in hp racing I think. Also everything will be 4 valve per cyl.
I know the issues we have in the cars I just hope they don't follow in the marine engines. I would run a Bg Moa oil additive to prevent oil ring issues and carbon in any of the new Volvo engines.

Mabey twin blue scorpions!!

Exactly.

That might be a long way off till I can afford one of these newer bad boy Dreamsickels.
I kind of happy with my little 425hp 220.
