Dyno Comparo: 2SS Auto vs. 1LE

aka Reckless · 03-03-2017, 12:48 PM

Just for viewing interest. My 2016 2SS with A8 auto and David's 2017 1LE MN6, both bone stock

should title this "yet another reason to choose a manual"

TransAmx2 · 03-03-2017, 01:21 PM

Just a random thought, could this have anything to do with the fact that the 1LE gets the upgraded ZL1 fuel pump?

I would expect auto to manual drive train losses to be across the board, not just at high end as the graph depicts.

A 20 or so HP loss on an automatic is 4 or 5% is typical and represents the additional driveline loss of an automatic.

Just curious, were these runs on 91 or 93 octane and how many miles were on the 1LE?

I had the same thought

Both on 93 octane. 1LE had 1500 miles versus my 3800 miles. I thought it odd they were identical up until about 4800rpm

Fuel pump as in the cam pump or in tank? But stock power levels it shouldn't be an issue there is plenty of fuel.

I would love to know if the 1LE uses either or both the LP or HP fuel pumps of the ZL1. I do believe it has been discussed on these forums that they are the same as the SS though. Would love that to be wrong though.

ULTRAZLS1 · 03-03-2017, 02:40 PM

Was the auto in 6th gear? Running 5th ~20 hp down from 6th

oneredry · 03-03-2017, 02:49 PM

Correct me if I'm wrong, but everything about the power train, even the fuel pump are the same. I don't' think its like the 5th gen 1LE where all the fuel components are upgraded.

Dirty air filter maybe

different days, I'm not a expert but the manual run was on a much cooler day, maybe that helped. Now take them to a drag strip and see who wins

13vertss · 03-03-2017, 03:09 PM

I know there sae corrected, but the 1le looks like the temps were in the 50's while yours was in the 80's. could that do it?

jdasnt3 · 03-03-2017, 03:30 PM

Looks normal and thank you for sharing. Both are great platforms. If you want to go fast in the 1/4 mile, choose the A8. If you want to have a fun car that you have complete control over, M6.
