PP vs. Non PP?

[AJP turbo]

I'd say there is no difference whatsoever ...just lower fuel economy so it's a lose lose if you ask me

[SHO-Time]

Ok guys, let's try to stay on topic. ;- )

My question again: Is there a measurable performance advantage in 1/4 mile times between a PP and non PP car.

Since comparisons become futile once we begin throwing in mods, let's keep it to 100% bumper-to-bumper bone stock cars.

Go!

P.S. I'll try to get times for my own ride when time permits.

(Going back to your first post) Even though the SHO is AWD, it's a reactive AWD system and will still spin the front tires. So better sticky summer tires can only help in the traction department. I can't speak for stock vs stock, but my brother in-law owns a PP and I own a non-PP. When we both had JUST a LMS V8 tune and raced from stop light to stop light, he was consistently 3/4 to 1 length ahead of me each and every time. This is where the difference in gearing comes to light. Click the link below if you would like to see our 1/4 mile times from this past weekend. Once again we're not stock, but you can gauge the difference between the two SHOs...They're close, but there is a difference.

I just wanted to clarify this one more time,the PP due to the 3;16 drive ratio will only have a very slight lead or edge from 0-60,its simple as thats.Z

Exactly. They're close, but there is a difference and it comes down to the hole shot. With all things being equal, the PP will beat the non-PP from a dig by roughly 3/4 to 1 car length every time. It's an undeniable fact that the gearing makes a difference.

Z the lead will continue or stay the same..not like the pp will be slower after 60

AJP i'm a bit confused based from your last post saying theres no difference whatsoever,has your opinion changed (whatsoever) .Z

2.76 gears will get you 140 mph with 20" tires at 6500 rpm.
3.16 gears will get you 122 mph with 20" tires at 6500 rpm.

It's about torque to the ground!

Please disregard my statement about there being no difference my head temporarily exploded then I regained my logic.

I was thinking it made perfect sense for a hardware change to have no change whatsoever and even make the car slower but then I regained consciousness and realized how idiotic that would be so I apologize.

  At the end of the day, we strapped on the old VBox and grabbed some acceleration and braking numbers on the long flat straight and were impressed. Acceleration-wise, it's a testament to repeatability, overlaying almost exactly on our 2010 Performance-Package SHO with a 5.2-second blast to 60 mph and a 13.7-second quarter mile at 103.2 mph (0.2 mph faster than the last one). Braking, however, was a big improvement at 106 feet versus 112. There was no chance to get figure eight numbers, but you can expect lap times to drop and overall g level to rise with the improved braking

So the PP is 0.2 faster in a quarter mile.Z

Great responses everyone, that's the kind of back and forth discussion I like seeing!

If I read the article correctly, MT was comparing the 2013 SHO PP to their original test of a 2010 SHO PP:

"Acceleration-wise, it's a testament to repeatability, overlaying almost exactly on our 2010 Performance-Package SHO with a 5.2-second blast to 60 mph and a 13.7-second quarter mile at 103.2 mph (0.2 mph faster than the last one)."

So the 2013 SHO PP they tested was .2 mph faster in the quarter (not .2 sec faster) than the 2010 PP. Mags rarely test the "base" version of a performance car, everyone I can find of the 2010-present SHO's are all PP.

You can argue about acceleration until you're blue in the face.

But you're overlooking the two features found on PP, which makes the upgrade well worthwhile - ability to completely defeat AdvanceTrac and the additional cooling. The front transfer unit already has a humorously small fill of oil, which seems to turn to peanut butter rather quickly, from overheating. The aux water cooling will most certainly prolong the life of that oil.

[SHOnUup]

The cooling features of the PTU and oil cooler are the 2 things I drool over being a non PP owner.

Checked my PTU fluid before heading to the track last weekend, and after a short 12-13k interval I already had a decent sludge build up on the plug again.

Do you have powertrain warranty remaining, Rich?  Hopefully your rigorous maintenance will keep the PTU out of the replacement hospital, but need to work up a longterm strategy

Power train is 60k right? At 48 right now, and we have the FoMoCo 100k bumper to bumper.

Fluid still looks pretty good though. It was full and had a light colored tone to it. Used a zip-tie taped to a garden stick to check the level. Pic, looks darker than the fluid was.
