TRD Supercharger increase MPG

Does a TRD supercharger increase MPG? Ive heard yes and no. I am in the condition to posibly aquire one. Just a little worried what the MPG's will be. I know a few of you guys have them so what are you getting??? Im getting about 17-18 city and 22 highway right now but I am stock. I will be getting Camburg Coilovers and leveling my truck with 285's soon. I know that will kill my MPG just thinking maybe a TRD Supercharger would bring it up a little.

THANKS!!!

 

i seriously doubt any kind of forced induction would raise mpg. my taco is n/a and never had anything else, so im no expert, but im like 99% sure its going to drop. and probably a good bit. From my past research iirc supercharger spins off of engine power and pulls more air in through the intake. this requires some tuning to get the air/fuel ratio fixed so then your forcing in more air which requires more fuel per cylinder. but like i said im no expert i could be dead wrong lol

 

You will loose MPG's with an SC.

 

It might but even if it does you will never see it. You'll be too busy enjoying the BRAAAAAAAAAAAAAAP! Whats the point of having one if you aren't going to floor it everywhere you go

 

7/10 times you'll get a drop. But if you're good with the skinny pedal you can use the extra power to your advantage and see a bit of an improvement. That being said $2500-$5000 buys quite a lot of gas.

 

with that setup no, and not even with the supercharger. you'll be getting about 17mpg as what i've been reading.

 

IMO, if you want boost, MPG is not a concern. A SC uses your engine to turn the screw, so there's parasitic loss. Think of that kinda like an additional AC compressor. It's going to drag on your engine. That said, there's probably some efficiency of getting the increased compression. But let's just throw all that out, because if you want more power, your foot will want to play. No one buys boost to granny it around all day. You will want to hear it. And the gas will burn!

 

Other than the SC, my truck is stock, I drive the speed limit and I still average 20-21.2 mpg per tank, same as before the SC. Passing and accelerating onto the freeway doesn't last more than 5 seconds or so, so I'm not sucking down any serious fuel.

 

Ive got a supercharger on my 1st gen. I only paid 600 bones for it. But anyways my gas mileage is a tad better but only if I keep out of WOT. I avg about 22 mpg on 32's I got a litle less then that without the SC. But I also drive my truck easily as well.

 

HAAHHAHAHAHAHAHAHAHAHAHAHAHA

 

I have increased my mileage on the freeway it makes the engine more efficient and doesnt downshift going up inclines...people who says it drops considerably dont have one to tell you....in the city if i stay out of boost its the same but if im in boost it drops so its all in all how you drive it....

 

My S/c increased my fuel economy by about 1-2 mpg's, when I'm driving economically. It decreased them radically when I hit pedal to floor

 

20 mpgs on my last fill up. Mostly freeway driving. The tank before that was 19 and that was doing some test runs in the hills after adding the URD pulley. The truck never downshifts on the freeway, even on some steep grades which I like. I've been boosted since leaving the dealer, so I cant say what the mpgs would be without the s/c, but I'm extremely pleased so far.

 

Yes it will give you twice the horsepower and half the miles per gallon.

 

Most people I have talked to (including myself) loose about 1 MPG.

 

thats a big fat NO.

my 2001 had a SC and it lowered my MPGs considerably. With all things realistic....The thing is that you inevitably gas it harder and more often with the SC, you won't be be able to help it as much as you think you will, so there alone your suffer. Then when you do take it super easy, the best i saw was 19mpgs when i used to get 21, so loose even when you focus on getting the best.

 

See this is what I am talking about. I understand why it would decrease MPG but then there are some people who have it that says they now get better. That is what baffles me! Maybe the efficiency at 2k-3k rpm is better but anywhere else its worse.

 

Honestly, its going to vary from everybody you will ask. My MPG varies from 16.5-18.5. That's the same mpg's I was getting before I put the s/c on, so for me it didn't change. It basically comes down to how you drive end of story.

 

I had a slight decrease around town and my highway stayed the same.

 

Keep in mind that if you just ask people what their MPG is bone stock (non-supercharged), you'll get a range of about 10 MPG. Put a supercharger on the same field of people, the ones getting great MPG because they're driving responsibly will do even better, the more aggressive drivers will lose even more MPG.

Krazie did say it best though, if you're buying a $3,500 supercharger for better fuel economy, you're wasting your money.
