For those with superchargers
 

How bad is ur gas mileage? mines was never great, but now it's terrible lol

Re: For those with superchargers
 

I get anywhere in-between 220-240 miles around town and about 290-300 on the highway.

Re: For those with superchargers
 

if your constantly "in boost" you will lose gas mileage...just nature of it. MORE power means MORE fuel used....

Re: For those with superchargers
 

if you keep your foot of it, have a properly functioning bypass valve and a good tune the difference should be pretty minimal. Once you start laying into it though its game over

Better than stock here. Got 18mpg 100% city last tank.

Re: For those with superchargers
 

once I went to a bigger SC...I never really measured MPG anymore....I kinda just knew...lol

Re: For those with superchargers
 

Sorry, I just saw that you were asking about gas mileage in boosted cars, mine is not.

Re: For those with superchargers
 

I would guess I'm around 13ish move now. Going on a mini cruise tomorrow, gonna see exactly how much I get out of a tank

Re: For those with superchargers
 

With Whipple and T56 see about 230 for a tank with 3.73 gear, helped alot going to a Cobra baffled tank, would let it get below 1/2.

Re: For those with superchargers
 

E85 all the time and when I'm driving it, I am regularly in boost and at WOT. So I usually get about 11.

Re: For those with superchargers
 

I accelerate pretty heavy and do about 75/80 on the freeway. I'm lucky to get 16mpg.

32VALVR & Mach828 I noticed that both of you have auto transmissions. My Mach 1 is an auto and I plan on installing a Procharger blower later on this year. What did you guys do to help strengthen the auto transmission to handle the added HP & TQ?

Aftermarket torque converter
Forged shafts
Race clutch packs and steels
J mod
Sonnax valve body and seal kit
Forged clutch drums
Aftermarket trans cooler

Re: For those with superchargers
 

I'm on e85 and also get about 11-13 mpg

Re: For those with superchargers
 

Mach828 thanks for the feedback!

Re: For those with superchargers
 

my question is on the automatic machs I know ford went way cheap on the internals,what will the stock internals hold safely.....my 99cobra made 432 on 8lbs with a novi 1000rr....if I can't do this safely I'll just go full bolt ons...
