2014 Silverado E85 vs gasoline acceleration testing
 

Given the fairly significant increase in power for the L83 on E85, we thought it would be worthwhile to go back and retest the acceleration performance on E85 fuel.

As expected from the chassis dynamometer data, the performance did improve.

Impressive performance numbers for a stock 5300+ lbs truck (200+ driver and a full tank of fuel so we were over 5600 lbs).

I did two runs on E85. They were virtually identical in performance so I didn't do any more runs since the data was so repeatable.

0-60 mph was a best of 6.96 seconds (6.97 on the run displayed in the attached graph). This was an improvement of 0.5 seconds over the best gasoline run.

1/4 elapsed time dropped to 15.51 seconds at 93.5 mph, for an improvement of 0.4 seconds and 2.7 mph.

Saw this on LS1tech :) Can't wait until we see more and more!

Thanks for the great information! It all sounds very similar to the LFX V6. Flat torque curve, high pressure fuel pump ran off of cam lobe, and great E85 gains are all the benefits of cam phasing and DI.

This engine on E85 in the Camaro would give the current L99/LS3 a run for the money. The 6.2 should be a real killer.

Thanks so much for doing this ! I really like the numbers for this engine.

very interesting.

Looking forward to the LT1 making it into the Camaro.

Like a bit of gas ever stopped a seasoned wine-o. :bonk:



(appreciate the info BTW!)

Too bad this engine didn't help GM in the grand scheme of things as the 2014 Truck Tests are out. That and I don't see whyt people are so excited for the 6.2 as it's damn near 100% carry over from 2013.

No one is overly excited about the 2014 6.2... this pertains to the future inclusion of the LT1 in the Camaro line and in the new '14 'Vette which is absolutely NOT 100% carryover.

this is pretty interesting! thanks for posting!

The new di 6.2 only shares 2 or 3 things with the old pfi 6.2.

I just picked up my new 2014 Sierra this week. 2WD crew cab 3.42 rear gear. Best truck I've ever driven and yes I drove the Dodge and Ford before I got the Sierra. I'm looking forward to what LPE can do with these trucks.

Congrats FrankT,

It's good to see that you're enjoying your new Sierra! We hope everything remains that way :thumbup:.
