Maker of twin-turbo kit for Corvette claiming massive (167%) city MPG increase.

This is like that 8 second Mustain (intentional misspelling) that got 200mpg or w/e.

OMG @ the Silverado's gas mileage... it made me lol

I had the same reaction. Red Flag Alert.

Heh heh... I wonder what our Boy Wonder Doug is up to these days? Prison? On the lam?

I got it:

We drove a Silverado from Bellingham, WA to San Francisco towing a Corvette on a trailer through the mountains and averaged 19 mpg for the trip.

That bi-turboed Vette gets much better milage when being towed by a Silverado!!

I wanna play too!

Your new HP computed from your old HP of 65 at Blower Boost of 6 psi is 91.54 HP.

2000 Honda Insight | 112mpg town (stock 49mpg, a 128.5% increase) | 97.6mpg highway | 91.5 HP (stock 65hp, a 58.7% increase) | 107 ft-lbs torque (stock 68 ft-lbs, a 33% increase)

Yep, I bet I could get those kind of numbers, even with a blower. So the 'Vette was driven with a full grille block, overinflated Insight tires, 35mph P&G, all the windows closed and electrical loads off, etc. On the highway, it was 45mph. Isn't that how everyone drives their Corvette?

So to sum up:

• take one part "grain of truth" (turbocharging's ability to increase thermodynamic efficiency),

• add a large portion of unsubstantiated, unscientifically obtained fuel economy claims,

• stir in dubious (overblown? pardon the pun) horsepower claims,

• sprinkle with cringe-worthy marketing speak ("interactive hybrid!")

Et voila! A recipe for diminished credibility and massive skepticism on the part of the EcoModder membership.

What is amazing is this guy can get away with saying this crap. I've owned Turbo Charged cars since 1981 and know what you can and can't do with them to improve gas mileage.

Slapping on a Turbo with out making changes to the fuel system is a recipe for disaster. Boost means an increase in cylinder and piston temperatures.
You have two choices to cool the cylinder add more fuel or add a water/alcohol injection to cool it. Either way you are not going to get better fuel mileage. Adding fuel mean less gas mileage and adding a water/alcohol mixture means less power.

Sure adding a turbo will increase fuel mileage if you drop the cubic inches of the engine. I can't tell you the people I have told not to just slap a low pressure turbo (4-6 psi) on a stock engine. I'd say 75% had major repair bills with a year or two or the car just never ran well from that point on. One the repair bills usually involved a new head gasket or a hole through a piston due to running a lean mixture. They never increased the fuel mixture under boost to compensate for the increased heat and pressure involved with adding the turbo charger. I've never ever seen someone get better gas mileage by adding a turbocharger to any car.

I could get 40 mpg in a Corvette with a turbo charged engine. I would pull the
5.7 liter and drop in a Buick 3.8L V6 Grand National engine.

So basically theyre saying I currently drive a 1988 Ford Thunderbird Hybrid?

Oh maybe the turbo has to be rear mounted to be a 'hybrid'.

Well in that case check out this sweet Festiva Hybrid
