I've seen a few guys on here saying that they are getting 5-7 mpg gains with twins. If twins cost around $3,000, they would pay themselves off in just over a year. (quick figuring and maybe not accurate) How many are running twins and can you verify these gains?

 

I've never heard of the kind of mileage gain by just adding twins. I'm gonna say that those are inaccurate numbers. If they are correct, sign me up!

 

That's kinda what I thought, but I just have my stocker, and I want to hear from those that do have twins to see what they say.

 

there is NO way that is accurate

 

Serious...

 

I'm gonna say that is innacurate. I could see maybe 1-2 mpg increase if you can keep your foot out of it, but I would bet it would be just about the same. My mileage has definitely gone down cuz now it's just way too much fun to drive...not to mention that turbo whistle is music to my ears!

 

X2, no way my mileage increased.

 

No increase in mileage here.... on my 02. Just more boosted air for a heavily fueled truck.

I daily drive mine at around 425 hp. Often go a full tank without increasing hp. No gain there either.

I remember myself in one thread mentioning pretty nominal but decent gains with my mods and some dude claimed an easy 5-7 mpg gain with twins. Riiiiiight.. but I didn't say nothin

 

I've not seen any hard data indicating that twins offer a large gain in MPG numbers over the stock turbo.

I think the MPG gain comes from having a large, slow-spooling single, and then transitioning to twins. But even then, the increase is usually 1 - 1.5 MPG.

no gain...more like loss unless you are overfueled.

it takes energy to spin turbo number 2...nothing is free in the world of thermo dynamics...

 

What he said above...

I saw no change at all in MPG, better or worse, with mine.

 

mine got slightly worse, cause i cannot resist hearing the different tones of the two of them

 

Yeah... and you have "special" twins too..

 

No mpg's, but lot's of power I bet!
