if it were my money, I would get the Edelbrock kit and schedule a dyno tune.

 

ya i would go with the roush...although that edelbrock looks sexy also

if your gonna do it, then do it right. dont fleabay and get the cheap stuff.

wish i had a extra 5g layin around for this stuff, oh well a man can dream

 

there are a few reputable dealers on ebay, he might find hte Ford Racing blower on inventory "fire sale". There used to be some guys who were offering vortech options for 'stangs that allowed you to nix the stupid TREX fuel thing and EEC. That way, you could run a 255 pump which are dirt cheap and go dyno tune and/or good custom tune.

 

2.3 whipple.

 

Do your research. Don't buy one based on apperance or a name brand. The Roush is Eaton roots blower as is the Edlebrock. However the Edlebrock is updated as it is a TVS Roots. It is not proving to be anymore efficent at 8psi than the Roush. Also all the fancy crap the Edlebrock comes with on the Mustang kit is not included on F-150 kit so don't be fooled. I have spoken with reps at Edelbrock, Roush, and Whipple and I became familiar with the kits and the function of the blowers. You won't be disatisfied with any of them. The power is there, as is reliabilty. The Whipple wins my vote as it runs cooler and provides more power per pound of boost thanks to it having less parasitic loss. What this means is that it takes less power to turn a twin screw blower than a roots. The difference is 20hp at 8psi. This difference grows with increased boost. By 10psi you can be looking at a 30hp difference at the rear wheels. With this comes added fuel efficiency.

Troyer and I did some comparision between my twin screw whipple and his Roush set ups and here are the results he gave me. My Whipple charged 5.4 uses 5.18lbs of fuel per minute at Wide Open Throttle. A Roush charged 5.4 uses 6lbs of fuel per minute at WOT. The additional fuel is needed as it takes more energy to turn the roots blower. As a side note your naturally aspirated 5.4 consumes 2.8-2.9lbs of fuel per minute at WOT. In addition at 9.5psi my Whipple provides me with 149% volumetric effeciency. Not bad when you think about it. A stock truck makes 300hp and mine makes 600hp and I'm only consuming 2.38 more lbs of fuel per minute. That sir is an effecient blower. Keep in mind that the Edlebrock produces the same numbers as the Roush.

Now you make think that because the Whipple is producing the additional ponies it will be harder on the motor. Not so. Each pound of boost will provide the same amount of hp. Your crank and rods will experince the same amount of stress. However when you are not using the hp to turn a blower its going to the rear wheels and that spells performance. Do some shopping around though. You can find some great deals on any of the kits except the Edlebrock which is way way overpriced. I have seen Whipples and Roiush blowers go for $4200 on a pretty normal basis.

 

Only finding them for around $4900 right now. If you're not in a hurry keep your eyes peeled. JDM dropped them to $3400 this past winter and they went fast. Made me sick cause I bought my kit used on ebay for $3400 two years ago.

Lethal has some good deals....they are about 3 miles from my employer

BTW, good writeup on the blower compo. How is your IAT setup? The mustang and tbird guys who are running roots type blowers go with the Lightning IAT tapped into a manifold runner.

 

Might want to look in to Whipple Superchargers as well. They are pretty good from what i hear.

 

I have yet to do this. Its something I would like to do this summer as I get time. Just ordered another pulley, pyrometer, and 80mm throttle body. Shooting for mid 12's at the track. The pyrometer in addition to my A/F meter will allow me to see just how much I can lean out the fuel without problems which will help considerably.
