Terrible MPG on Whipple setup

[watisthis]

P1sc stage 2 w/ 95lb injectors and I'm getting a happy 9-10mpg in the city. More so worried about my creeping higher ECTs and CHTs in the single digit cold.

whipple probably cost 70hp to turn the blower and if its a whipple tune its probably a touch Fat for safety -but that being said my Hellcat gets 15-16 around town and 24-25 hwy with a bigger less efficient engine ...10-11 is a bit crappy ..Now a centrifugal blower totally different experience i got better than normal on my last mustang ...maybe this is just normal for this setup

It probably does take 70 or more hp to spin the compressor and they do run it fat to protect the cats, but both of those are only true at WOT.

I see boost and low mpg. And think that’s a good thing.

Exactly

My highway MPG increased by 1.5 MPG but my local driving went down 5 MPG. Probably because I enjoy making the blower do some work.
If I could possibly keep my foot out of it, I'm sure the MPG would increase.
Alas, that wont happen because the giggle factor comes into play when my foot gets into it.

2016 stage 2 whipple 315 gears 6r80 trans. Average 13-14 mph mostly city driving.

Something is off, I get 18 on 93 and 14 on E

Agreed

I have a 2018 PPL2 manual stage 1 Whipple I get about 12-13 just driving “normal” can get as little as 6-8 with “hold-on” driving. I usually drive in sport mode. If I switch to “wet mode” on the freeway @ 75-80 normal driving I get 27+ mpg. I’m not sure what wet mode would have done before Whipple, I didn’t use it.

i get 15-16 mpg on the hwy on E85

Probably very little change when NA.
It’s likely that wet mode slows the throttle so much that boost rarely occurs, making it drive a lot more like an NA car.

Wet mode makes the throttle sluggish on the low end. I feel like it also makes the traction control more sensitive, and the sport mode allows a little more wheel spin.

At least on my 2016 stage 2 tune, Whipple's "normal" is basically the same as sport mode. Here's a graph from HPTuners data because I'm a nerd:

That’s right on wet mode power is cut, but if your just cruising down the fwy. Why not turn it on to save some gas $$. That money can be better spent for more mods.

 

[engineermike]

While cruising, wet vs normal will not make a difference.

While cruising, wet vs normal will not make a difference.

Just where your foot is holding the pedal in relation to the floor. It can be slightly beneficial if you don't have fine motor skills on your ankles.
