I don't see why the Turbo kit wouldn't be more reliable and more friendly at the Pump if you didn't turn up the wick. Whats your thoughts since you plunged into the unknown?
thanks for the info 
I think a turbo equipped truck will be as reliable, if not more reliable, than a KB equipped truck - given the same boost level.
Why?
1. Less Heat = Less chance of Detonation
The turbo creates less IAT2 temps than an Eaton or KB. KB's are great. They definitely make power, but at a cost, heat. Frank5L ran the 1/4 mile and saw 109* IAT2 temps through the stock intercooler. Those temps are fantastic. For me, I could run the 1/4 and I see 151*+ temps at the end. A 42* temp drop means less chance of detonation and more power.
2. Less drag on the motor = More power
Superchargers are great. I'm not knocking them. I've had 5 supercharged vehicles before the HD. But it takes power to run it - and a lot of it - driven off your crank. Although a supercharger makes more hp than it robs, by switching over, you're freeing 60-100 power robbing ponies.
3. Gas Mileage
Hmmm... consider this.
You're driving on the freeway at 70 mph and turning 1900 rpm.
In a supercharged vehicle, you're also turning the supercharger which saps a certain amount of hp and hence fuel.
In a turbo equipped vehicle, exhaust heat turns the turbo. My guess is that I'm going to gain gas mileage (IF... and this is a BIG IF.... IF I can keep my foot out of it).
That doesn't mean everything is all roses. There are some negatives.
1. I think the torque curve is flatter with the KB or Eaton.
- However, the is a chance for greater overall torque and more area under the curve with the turbo. That's why the Powerstroke Diesels run turbos and those things haul.
2. Boost lag
- If you don't run the right turbo, you'll have lag. Modern turbos and better understanding of pairings make this a rare thing however. Also you can run a higher stall converter so you make more torque when you launch. However, those with stock converters have said they only feel a half a sec delay and its OMG hold on! So, I'm hopeful this won't be a big issue.
3. No turbo kit which is 50-state legal.
4. Supercharger doesn't have all the tubing that a turbo requires. Which makes it easier to package.
5. More underhood heat.
- Okay, big deal. What really matters here is your IAT2 temps.
Stay tuned,
- phil
