I know I am not too familiar to you guys as I have mostly been lurking around for a while, but I work for a local shop here in Pensacola FL part time and have been envolved in quite a few supercharger builds on various Mustangs. The last Mustang we did was a 2008 that we put an Edlebrock E-force on, and I will tell you that less power or not, more expensive or not, that would be the Kit that my money would be put on unless I just ran across some stupid crazy deal on anything else. The Edlebrock kit was straight forward and very easy to install. All of the wiring extensions and hoses are pre-made to just the right lengths and ultimately made for a cleaner setup as well as easier install. The manual was very detailed and easy to work from. To be honest with you, the added price is worth it all day long in my book.

 

FWIW the Whipple kit was the same way. 60 pages of detailed instructions with color pictures with captions and arrows. I haven't dealt with a Roush kit but having used some of there other products they to were an easy install with excellent directions. It was more of a pain and took longer to install my headers than it did the Whipple. Mind you I bought my Whipple used so all the parts were in one box and one bag so I had to sort through which screws were which. It was truly a bolt on part. But even if there was some uncut or unclear areas I can't see it being worth a $3000 difference in cost.

 

Let us know what you decide I am right there with you looking at the Banks for 2010, just waiting to build some other things out first. Hope to have it on by the summer.

 

Update from Banks:
Called and spoke to Chuck at Banks today. According to him they don't currently have any SC's for an F-150. They used to offer one, but sales just weren't there. He said there may have been some NOS stuff being sold in the past, but its all cleared out now. He said they might consider it for 09-10 F-150's in the future.

The Whipple is a good setup I just don't think it's best for me. I really am considering all options.

Here are my reasons for thinking e-force best fits my needs:
1. I don't want a hot rod truck. I've got a 73 firebird 455 4spd for that. Well when it's done it will be anyway

2. I prefer not to push the bottom end or tranny more than necessary to get the extra power I want for towing so 40 extra rwhp at 10psi is in my thoughts a risk to "me".

3. Right or wrong I believe the fact the e-force gets its power at 4-6psi is safer for the engine than other higher psi models.

4. To take full advantage of the 10psi I'd also need long tube headers, high flow cats, true duals, etc.

5. The long intake runners on the e-force allow a large amount of the trq very early in RPM range which is what is best for towing. Over 450 ft lb at 2500 rpm. Diesels are good for towing cause they make trq early. I need low end off the line power and not so much topend power. A lot of the others make more trq & hp, but don't make it until higher rpm ranges.

Anyway hope this clears up why I think e-force is better for my needs. I might be wrong and time & my wallet will tell I guess.

Oh Yeah "bankrpt" I'll be down your way for the "Petit Jean Swap Meet" maybe I'll see you then for a ride.

Thank you for all the suggestions & comments.

I'm going to call BC auto about there valve body. It's $50 more than Troyer so I want to understand from their prospective how they believe it's better. Summit has some pretty good "derale" brand coolers for a good price so probably going that route.

 

Ok.sounds good also might want to throw in a tranny temp gauge

 

Wondering where the 10psi comparision is coming from? All of the kits out there start at 8psi. Edlebrock like Roush likes to wow folks with flywheel hp numbers. Not knocking them just saying. Its also note worthy that the Whipple kit for the trucks was intended for towing. It just so happens that its a great kit for building up and hot rodding to. No doubt the Edlebrock is a great blower and also good for higher hp. But bottom end grunt is there with any positive displacement blower. Its the nature of them. And don't be fooled 4, 6, 8, or 10 psi is only going to make so much power. Edlebrock nor Whipple nor any other company has magically found a way to make 6psi more than it was before. At what rpm the blower is able to make the boost and how much energy it takes to turn the blower is really the only key factor there. For example the Roush 6psi non intercooled kit puts down 300ft lbs to the rear tires at just 1700rpms and makes peak torque of 370+ at 3500rpm. Below is a Whipple 8psi kit which like all blowers in the real world makes 7psi and you will notice it putting down just over 350rwtq at only 5psi and 2600rpm. At 5.5psi its laying down 400lbft at 2950rpms. I'll let you make additional comparisons. I would ask Edlebrock for some rear wheel numbers before I ever spent $6-7k.

 

Something I remember reading about the edelbrock kit was the numbers they publish are if you take your truck to their facility, they install the blower, and do their own custom tune...

Honestly the long intake runner design sounds real good in theroy, but on these blower motors I really don't know if it makes that much of a difference. Nothing your butt-o-meter will tell most likely. It's one of the reasons I bought my Saleen, but in the long run I wish I had the whipple.

Do yourself and your wallet a favor. Buy the whipple with 39# injectors and a JDM tune and save $2000-4000. Spend that extra money on a built transmission from BC Auto and some long tube headers(lowers cylinder head temps aka engine last longer when towing). So for the same amount of money you were about to spend on that edelbrock blower, you will be more reliable and have more power then the edelbrock setup will give you.

 

And if the Edelbrock blower is a roots blower the Whipple twin screw will give you a lot color charge temps at the same PSI as the roots!
Thus being more efficient and essayer on the motor.
You could probably make the same power with the Whipple running 2# LESS boost.

Well it is the new TVS(2.3L??) blower design, which is better cooling properties then the older 1.8L roots design like the Roush. The edelbrock honestly is the best designed sysyem for a stock shortblock truck, but it is no where near worth the extra $3-4k over a whipple/roush/saleen setup.

 

Oh,
so the TVS is better then the old roots but still not as good as a twin-screw?

Phil

 

Damn right!!! Bottom line its still a Eaton just tweaked a little. I'm sure they will sale a lot of them because of the name just like Roush did. When they do some actual head to comparisons and post some RW numbers then I'll be impressed.

 

I think he should get the Edelbrock kit and be the Ginni pig for us on this site.

We need someone to get some numbers for us...lol

So I called Edlebrock today and waited on hold for there tech dept. Only about 5mins no biggie. I started asking questions about the Eforce. He told me the kit you see online is 5-6psi. They did not have rwhp numbers but he said from there experince its generally a 25-30% loss. So that would put rwhp between 334-350 and torque in the 350-380 range.
By comparision these are the same numbers the Roush non intercooled kit provides for $2500. I also ask about fuel consumption. He gave me mpg figures of 10mpg towing and they saw a drop of 2-3mpg from stock with no load. (Wow I dropped .8 mpg and more than doubled my rwhp.) I said no this is not what I am asking. I want to know how much fuel the truck burned at WOT on the dyno. I waited on hold for about a minute and he said they didn't have that data. What? How can you develop a kit and tune it without knowing this? Anyway I told him I was comparision shopping and just trying to figure out which blower took less energy to operate. Again he said they had no data. So I thought I would put my numbers out there and we can at least compare if anyone can obtain this info.

At WOT my engine consumes 5.18lbs of fuel per minute and produces 419rwhp with a volumetric efficency of 149%. (A bone stock truck consumes an average of 2.7lbs and produces around 205rwhp) A Roush blower on the same boost same setup consumes 6lbs per minute. This of course is a testimate to the efficiency of the Whipple. My thinking is that if this Edlebrock at the same boost levels produces the same numbers as the Roush then its not anymore efficient. Perhaps at higher boost levels it runs cooler than the Roush. I'm just wondering if this TVS technology is all it's cracked up to be and is it worth the $3k difference in cost?

 

I can't find install instructions for the whipple. *Anyone have a link? *I assume folks are buying these from JDM? *Theirs is 3400k. *I assume the take notes about my mods and create a tune. *So I'd need to tell them It I install a valve body. *Not saying I'm going that way, but I'll look into it.*

The roush kit makes you buy plugs, injectors, and possibly a new motor drive pulley. *I'm assuming whipple is the same plus the cost of a tuner?

The e-force comes with tuner, injectors, plugs, and a larger throttle body.

What are the extras required for whipple? *Need to minus those from e-foce cost and add to whipple for a true compare. *

 

The roush comes with 39# injectors
