Meant it more as a reference to the assumption of sand bagging, if they are purposely doing a before run they may try to take it easy off the start, causing the slower reaction time and its really hard to see but kind of looks like a 1 second difference in 60ft. If that is true I would expect they took it easy getting into the gas or spooled the turbo after and not in the before.

just saying it seems fishy

The non-tuned truck ran what appears to be a 2.33 60' time. In the best case, I would not expect a stock-tired 1/2 ton to run much quicker than a 2.0 (my Lightning and Tundra both ran right at 2.0 stock).

Not to sound rude, but I probably wouldn't have posted these results if stock EB trucks were out trapping your truck. I couldn't care less what the 1/4 time was as there was a trap speed improvement. 90whp should be getting the truck close to 100mph trap. So if the slip read, 2.5 60' 14.6@100 that would mean more than seeing 14.0 @ 96. I have a feeling this is going to be a hostile thread.

Agree 100%.......... "tuned" trap speed is weak to say the least.

Was this at the same track and same day?

We've seen untuned EB's turn those numbers. What am I missing here ?

engineermike

If you start off running 14.4 at 95 mph, then a 90 rwhp improvement should run about 13.4 at 102 mph.

Joewee3.5

If you take the 60' from the tuned run and add it to the untuned run you'd be running a 14.8. A 2mph increase in trap does not mean 90whp no matter how you slice it. Is there some data logging happening on these runs? If the tuned version is really ripping out of the hole that much harder then hp is being pulled further down the track.

engineermike

Is the factory speed limiter at 95 or 100 mph? And is it progressive? It doesn't seem like any 2011's are going over 95 in the quarter without a reprogram.
