Well, MM&FF was realistic with the information they provided. They had teething problems at the outset. They did not get the car into the 11s on the first try. The 2-row intercooler was insufficient and detonation was an issue. On the second or third pass, the stock clutch got smoked. In the next issue, the they installed a 3-row intercooler and clutch. That's where they nailed a string of 11s. Yes they did.
As for the stock 19 lb. injectors in the project car, they were at an outrageous amount of pressure and maxxed out...I did the math to verify. The BSFC had to have been pretty low...too low for comfort if you ask me...but they did run the number.
I've been modifying cars for 18 years, and I generally don't believe anything manufacturers or magazines claim regardless if they're for blower kits OR turbo kits. But in my general experience with the Procharger, MM&FF was not far from the truth.
The underlying issue, and I think you'll agree, is that you can't bolt on a kit and expect to run the number. Tuning must be performed. The infrastructure must be evaluated. Can the short block hold up? Will the radiator be adequate? Is the ignition up to the task? Will the stock clutch hold ? How about hardened axles? A 6-point bar, a scattershield, a driveshaft loop...all needed to pass tech? How about strengthening the torque boxes, or installing subframes? Are the basic skills even there to pilot a car into the 10s or 11s?
I have a hard time believing that anyone can install a turbo kit on a 5.0 and expect to run low 11s without needing additional parts. If what you're saying is true then I bought the wrong kit.

I don't doubt MM&FF got their car into the 11's, but I still find it very hard to believe it was with the stock injectors. Too bad you can't find the article so we could see exactly what it said. I've seen the duty cycle ratings on the different injectors and it takes alot more injector to make the same power going forced induction that it does NA. I've seen a couple of cars in my day run high 11's NA with 19 lb injectors, but boy were they leaning out on the big end. No way would I try that, even on a bet with a blown car.
I do agree that tuning is the most important thing when it comes to blown cars. It dosen't matter how much you have in it, if it isn't tuned right, you can either end up with a boat anchor or a high priced, slow car.
I, nor would anyone else I hope would believe you can just add one of these kits and expect to run those kind of times. An automatic can eliminate the driver skill needed to pilot a car too those times. Yes other things like suspension, safety equipment, and a better cooling system have to be addressed before those times can be achieved.
With the ability to turn up and down the boost when I want and the fact I don't have to turn my motor to high rpm's to make boost, is just a big plus in my book. As I said both have pros and cons, it all up to the person to decide.
