Hi, this is my first post, so please bear with me......

Just purchased a 02 HD 150 3 days ago, it rocks, but it still needs more power. My question is what mods can I do to give me more horses.

What are the best, chip and supercharger pulley combo to go with? How much HP can I realisticly expect to get? How difficult are the modifications? What are the disadvantages to them?

Thanks for the help.

 

Get chip custom tuned on dyno, FIPK intake, and 6# lower. Those are your basic mods. And from there there is a whole lot more such as electric fan, torque converter, water pump, traction bars, sway bars (handling), etc... Don't forget plugs (Densos)

 

*cough* --8 lber-- *cough*

see sig...

 

welcome to the site, and congrats on the HD...

post pics/build # when you get a chance.


anyway, i'd recommend the basic chip/filter/pulley combo to start out

 

Slingshot, what differences will a #6 make compared to an #8. Im new at this so be specific if you can.

Harley 356, which manufatures would you recommend. Can these mods be done by myself, how difficult is it to switch the pulleys. Do you need to pull alot of other stuff off to get to them. What are the negatives of adding these things.

Ricekicker, do you know anyone in the Indy area that dyno tunes?

Thanks for the help, anyone else have any great proven combos that you would recommend.

 

Hi TonyJ,

Welcome to F-150 Online!

And congratulations on the ultimate Ford truck too, by the way, the 2002 supercharged Harley SuperCrew is as nice as it gets.

There are *many* things you can do to increase power output and improve performance in these supercharged Harleys.

Perhaps the 2 most effective things to start off with are to optimize the pwoertrain programming, which you can do either with our single or dual program Superchip or the new Superchips Micro Tuner, and then open the restriction in the air intake tract with the Air Force One intake kit.

Our performance program and the Air Force One intake kit will net you about a 50 horsepower gain on the 2002 Harley, depending on exact altitude & fuel quality.

You can also raise the boost level of course, the '02 Harley has 6 PSI boost stock compared to 8 PSI stock for the Lightning. These Eaton M112 blowers can be taken all the way up to 16-17 PSI boost, given proper tuning & fuel quality, it's all a matter of just how much additional power you want to make. Keep in mind that any increase in boost level is going to require custom engine tuning as well, and a breather cap should also be used to vent the additional crankcase pressure.

The best thing to do would be to give us a call here at Performance when you get a chance, as we specialize in the performance of these trucks so we can provide any parts needed, as well as custom tuning and proper advice on what parts to do first, what will affect what else, what you will need to get to any given performance level, etc. We can easily help you map out a proper upgrade path to make sure you're getting the best bang for the buck in each of your performance modifications. With simple bolt-on parts, the performacne of that vehicle can be signficantly enhanced, gaining the first 50-100 additional horsepower isn't hard to do in these vehicles, and even more is available for those who want to make really big power.

How you use that vehicle will also be a factor, for example, if it's going to be used for towing, that needs to be taken into consideration with regard to the modifications to be done.

Give us a call when you get a chance & we'll be happy to go voer all of this with you in detail, so you can give it some thought, & we can provide any performance part you could ever want or need for that truck.

Best of luck with your truck, & we hope you'll hang out here with the rest of us here on F-150 Online in your spare time!

 

for a chip, i would say get one from one of the major tuners on this board. Same goes for the filter, and maybe do the JL ram air kit. For the pulley, you might be able to do it yourself if your good at that kind of stuff. And if you do the upper and change it to a L's upper, you need like a ASP pulley puller so you don't damage the snout.

good luck!

 

Hey Mike,

Few or so months ago when I got a truck you invited me to call you to discuss mods for it, which I did. I left you message with receptionist 3 different times over 2-3 weeks. You never returned any of my calls. Too bad cause initially I was impressed by your attitude.

Mike, does your shop do all the work there in Virginia or do you have shops throughout the country that can do the work you wrote about. I live in Indianapolis. How much more HP would the chips you wrote about get me. How about the pulley? Does the # of the pulley translate into how much boost it will provide?
I use the truck just to go back and forth to work and play. Every now and then I will put one of my bikes in the back and go somewhere, no towing. I just to increase the low rpm horsepower so it will smoke the tires off from a stop light.

Thanks for the info.

 

The # associated with the pulley roughly correlates to how much gain in boost you will gain with it on a Lightning . The HD has the larger upper pulley so you will not gain as much... with the 8 lb lower on my HD I went from 6-6.5 lbs up to 12-13 lbs (depending on weather--cooler air = more boost ). So I gained 6-6.5 lbs of boost with an 8 lb pulley. Others results may be different--I am in west Texas and the density altitude runs from 3000-6500 ft...
As far as the cold air intake? IMHO don't waste your money. Do the factory air box mod (learned this by reading the nloc board) and add a $40 K&N panel filter. Several guys have done extensive dynotuning and found that on a '99-up supercharged 5.4 that the K&N alone was worth 2-3 rwhp over stock, the filter with the air box mod was worth 10.5 rwhp and the $300 CAI was worth 12 rwhp. 1.5 hp was not worth the price difference to me!

 

Thanks Slingshot, What is the nloc board. Does it say how to do it? Will it still look stock? Do you have to pull off alot of parts to change the pulleys. Can you just change the upper or just the lower, or do you change them both together? How much time do you think it would take on average to change a/the pulleys? Thanks for the info.

I'm not sure about 16-17 psi on the Eaton, that sounds high. Roots blowers lose effeciency as you raise the boost, not to mention producing more heat. I may be wrong, but I think 16-17 psi is stretching the limits of the M112.

There was a pretty good tech article in Truckin' last month I think, does anyone have it laying around close for some numbers???

John

 

The article in Truckin' was done on an L, they stopped with the Eaton at 14.7. Higher than I thought.

Anyone read that article? I'd like to know how the Ken Bell does with 93 oct. fuel at higher boost levels.

What's the highest running here on pump gas?

John

 

Tony, contact me at our shop if your interested in modding your truck we've done a few L's and my boss has a 03 Cobra and I do 2other 03 Cobra's that come to the shop every other week to test and tune on our dyno jet then we go the the drag strip about 5 miles away to check 1/4 mile times E-mail me at dlfine1@juno.com
