I can vouch for that. What I used to do anytime I was waiting to turn left was to keep my left foot on the brake and the right on the throttle to keep the engine rpm up. When I got a break in traffic it would go and not fall flat on its face.

 

I disagree....

A positive displacement supercharger, particularly a twin screw( read not a centrifugal) will have nearly instant power gains felt through normal driving. Many of them will create useable boost from 2500-3000 rpms and up. There is a reason many bracket racers do not use these types of chargers, the power comes on too strong too fast and makes hooking up that much harder. Many of them prefer a centrifugal or turbo because it takes load and rpms to build boost. HOWEVER...for a street application, especially where towing or hauling, and bottom end power is Very necessary, a turbo charger is not the way to go-UNLESS you are going to pull the motor, rebuild it with a balanced and forged rotating assembly, slap twins on it and call it a day...then my friend...turbo all the way.....but who has the money for that? That's enough to buy another vehicle! I have personal experience with superchargers, and one installation I did was on my truck which I towed with regularly, and it made all the difference in the world.


Here are some fun projects Hennessey has done. I talked to them a while back to see if they had a blower kit for my 6.2, and they said they have had several customers use the Raptor kit with success on their Super Duty trucks, so I should think it wouldn't be too hard.

Just my 2cents.

 

This sums it up perfectly, I couldn't agree more. Also, diesels in general are designed from the start not have that instant power response that gas engines do. While both SC and turbos do the same thing in theory, the two power adders are very different and for a gas engine it's an SC all the way for the day to day real life work we want and need these trucks to be.

 

Anyone hear if the SD 6.2's will have a performance increase or other changes in the next model year?

 

Based on Fords (gas engine) history, I would say eventually, but who knows when and how much.

 

The F150 Eco Boost puts out more torque than the flex fueled SD 6.2. I'd get the HD F150 put I'll be very close to the max payload.

I would say that 4v heads are in the SD 6.2L future. As for the eb HD... we have one and plan on maybe taking it to the next OH meet , that is if they would let me show up and play

 

I currently have a very low mileage 2002 Ford XLT 2WD CRW SRW LB F350 7.3PSD. Need a 4WD and short bed. You have some interesting products, but I don't want to have any problems with warranty issues. I travel and tow. If I have a problem on the road, I don't need to get into a pissing contest with an out of town Ford dealer over add ons Also looking at a Ram Laramine with Cummins. I'm in no rush.
Maybe there will be a few extra foot pounds of torque in 2013.

I've been searching for a supercharger since I got my 250 last June. I am definitely interested if the price is right.

 

posted twice accidentally

 

as I only tow an enclosed trailer with a few dirt bikes and ATVs ... Im looking to run my super duty into the 13 second range with this puppy ! and a heavy promotion on the way out of the military ... Im GAME.... with a warranty

 

I doubt you could keep a factory warranty with this thing.

 

If they could come up with a SC kit, that could be installed by an "authorized installation shop" in order to keep the factory warranty, and 5 Star could come up with a tune to deal with the fuel, shifting, and everything else required, I'd drop 6k right now. But that would have to include installation, and programmer. But that is just me.

 

considering the basic kit for the F-150 is $6200 just to reach your mailbox, I highly doubt dealers could get the system to be discounted enough to have install + Supercharge = $6000. Installation alone would likely cost $1000-$2000.

 

How about a 4 inch stroke 4 inch bore motor from the factory
Instead that would help help the low end torque
