Pentastar performance upgrades

[loveracing1988]

Actually, that's a value judgment. And you don't get to make it for my truck.

I might prefer the supercharged Pentastar to a Hemi, whereas you might not. That has value to me that you haven't accounted for in your math. It's just just about the bucks sometimes.

And again, nobody in this thread asked "should we"; it's all about "how" here.


Knowing the origin of the tick, and that actual Chrysler techs have stated in no uncertain terms that these engines have a design flaw involving low oil pressure under loaded idle (idle in D), getting less oil up to those overcomplicated MDS lifters than is needed to lubricate them properly, is troubling.

I don't HAVE to know a hundred people who have crashed doing 1/4 mile drag passes on a 5/16-mile long track in order to figure out it's probably a bad idea.

All we're asking is that you keep your "get a Hemi" out of a performance thread dedicated to our Penatstars. We'll be the ones to make that judgment, thank you very much.

You know the sad thing is ripp came onto a jeep forum I'm on offering their kit for the v6 grand cherokee and people said the same line "get a hemi" I defended the people who wanted to run the supercharger because in order to upgrade to the hemi in the grand cherokee you have to step up trim levels. I defended those people because I saw a value to not getting a Hemi in that platform if you wanted the base model.
In the ram the hemi can be had in any trim level but the hfe.
So if you want to spend $5700 to get V8 horsepower out of your V6 ruining any advantage to having the v6 go for it, I honestly don't care, it is your money, but when you blow up that weak 845rfe transmission or melt a piston good luck.

We're not saying your wrong, in fact you are probably right. It's just not the information we are looking for...

Fair enough?

I traded with another member on here. He got my single exhaust and bumper and I got his dual exhaust and bumper. It's the Dual sport from a 2015 Hemi R/T. The sound is awesome!

Its a exact swap. took about 30-40 min to swap them both out.

Here are some pics of the before and after..

Sweet looking. Why did he want to get rid of it? Lucky you

I don't know why I didn't mention this earlier but there is a member looking to swap in the WTB section of the forum right now...maybe even two.

WTB? not sure where to find that. Can you point me in the right direction? Thanks

Exactly. Well said. Sorry if my version was a bit incendiary, but it gets a bit old seeing "not worth it; get a Hemi" when that's not what we're asking.

Argh! And I'm not in a position right now. Bad timing. Thanks for the heads up, though!

He didn't like the cutouts in the bumper and wanted the exhaust tucked away. So the trade worked out to us both getting what we wanted.

Throw twin turbos on it and call it the pentaboost!

But seriously though I really like the penta star and enjoy driving them (200, charger, grand cherokee I have driven) but boosting it would negate all its best qualities. Which are fuel economy and reliability. Assuming you bought your truck for those two qualities why the hell would you sacrifice them?

Thanks for that, too bad he's so far away. Arkansa and I'm in eastern Canada

Sorry, I forgot about that...You could always post a "Want to trade" (WTT) for yourself and see if there are any Canadian takers.

That's a great idea. I just returned from a 700 km run and I calculated my milage, I got 10.7 litres per hundred kms. My truck just turned up 10,000 kms and this trip I really drove a bit more aggressive. When you put the peddle down this truck really wants to go. When I passed 3 cars in a row yesterday my wife looked over and said I was crazy, lol.

Just wondering if anybody with the Pentastar has tried premium fuel as oppose to regular with ethanol added. If so, were there any improvements?

There will never be any improvements unless you are tuned for it. If you go from 87 to a 90 or 91 with no ethanol you might pick up a little mileage but you are also burning more octane than needed which will cause carbon buildup.

Our engines are built to run e85 so this may not be as much of an issue for Pentastars. I noticed with e85 it feels more sporty and holds gears longer. I've never tried 91...

No, they are built to run 87 with programming to run e85, hence the mileage loss when running it. I have ran e85 in my wife grand cherokee and noticed a slight increase in power and a 30% drop in fuel economy. It knows to advance timing because of an alcohol sensor, running premium won't trigger it to advance the timing because it won't have over 10% alcohol.

Actually, both my buddy and I have tried midrange (89 here vs. 87) and found a small improvement in power and mileage, especially in the summers here. Probably a lot of that is the extra octane offsetting the tendency to knock with our extreme heat (EDIT: try to knock anyway; the knock sensor pulls it back of course), but even in the winter it seems to make a little difference.

Haven't tried premium (91/92 here) yet, but my buddy has, and he said he saw no improvement. But it was just the one tankful, and it might have been during cooler weather.

A friend of mine just told me he tried stabilizer with ethanol neutralizer additive. He says it was a little better on fuel getting an extra 80kms on a tank. Why bother with so little improvement.

Yeah. Truck runs fine on 87, runs a little better on 89. Dunno about 91/92, but I'm not spending the money to find out right now.
