The weakest part in most smaller ford engines have always been the rods. The 7AE's are pretty weak, The FBOCA's are ok.. ( there was a third rod used and it wasn't much better ) but none are as strong or as good as a treated small block rod. All the rods ( stock ones ) are so out of balanced as well. Goin for RPM's with an unbalanced bottom end.. wouldn't last too long.



Theres a lot of fast trucks.



Theres some of it... What you want and what others will give are 2 different things. Come to a meet sometime, I'll let ya drive it.

hey...GO DISCUSS THIS **** ELSEWHERE!! IM TRYING TO DO SOME RESEARCH AND YOU ARE NOT HELPING!!

now, are centrifugal superchargers universal or do they need to have a specific application? i know all the right people that can help me with the install of the supercharger, possible new bracketry fabbed up, and plumbing of intake and inter/aftercooler.

can someone tell me the difference between and intercooler and aftercooler? is there any?

A centrifugal and roots are the same idea just in different designs but they do both achieve the same things. A roots type (as you can tell from this thread) can fit on a variety of engines if you know someone who can not only tune it but do the engineering side of everything. If one of your buddy's is willing to do it for free it will save you big money. I recommend trying Vortec superchargers if you're going to try a centrifugal.

Oh and by the way, whoa there turbo.. its called a discussion forum for a reason.. if you want a site where you're required to abide by the strictest rules around and cannot talk about anything remotely off topic in a post without it being locked go to Generation-Edge.

i didnt know research involved yelling at people to give you the answer

research -- Scholarly or scientific investigation.

i know ur not yelling at me! also like stated above if u know the right ppl for the install then they would tell u to buy an ATI or Procharger yes they are made by the same company, Centrif blower would be the best thing as u can do more to it(that was told to me by a very close friend who owns a funny car nd yes he does race it!) but roots is old school nd some say are stronger.

i said i knew the people that could install it or get me a deal on having it installed. when someone is going on about their motor upgrades and replying to everything said about their truck being or not being fast then thats wut gets on my nerves. those of you keeping on topic and asking questions that can pertain to this topic i dont care about that cuz you may be helping me. and those people i know, like myself at times, can look at something and the directions and put it on better then the manufacturer suggested (just an expression, no need to flame about the factory comment). they dont always know how stuff works and wut can go on something.

now about this roots thing, is that a full blower setup or wut? i cant tell if this has been answered in a roundabout way or not, but are centrifugal chargers universal pretty much?

A "Roots" type charger is a full blown charger. All of those big *** engine you see with the scoops sticking out of the hood with the 3 circular intake ports with butterfly flaps, well if you look below that you will generally see a very large pulley and belt running down to the crank pulley.

Centrifugals are not fully universal. You definitely need friends in high places for that. I'm talkin fab-shops, hose houses, and speed shops. You'll need parts and service from all of those places if you're gonna fabricate your own kit.

As far as Doug goes, i'm sure he can design a supercharger system program. All he has to do is dial in new numbers for timing, fuel tables, and a few other areas, that i'm not too familiar with. But for that matter, with the right interface software you could do that yourself.

This statement goes with anything you put on your vehicle that is going to affect performance. If you change anything, you are testing/pushing the structural integrity of the factory parts. If you go with a supercharger setup *I* highly suggest looking into the manufacturing specs of the supercharger. D could tell you more about this kind of thing in specifics, as i have never boosted a Ranger. My knowledge is still limited on the Ranger, as i just came from Cavalier. But as an example, I had 11.75:1 compression on the cavy before i boosted it, i dropped down to 9:1 because i though this would be low enough to handle 10lbs...WRONG....

I got lucky and it just blew out a few gaskets when i revved it the first time...During that rebuild I called around and got some specs from a few companies and my suggested compression was anywhere from 7.5:1 to 8.25:1. BIG Difference from what i WAS running. Granted this was a turbocharger, you will basically get the same kind of problem that i did if you don't do your research.

I got really lucky with my screw-up. I know guys who have had much worse happen to them for smaller screw-ups. Dropped rods, blown and cracked heads, you name it.

You can make a centrifugal work for your app. You would have to custom fab one because at the time there is nothing for truck. Vortech sells the unit apart form a kit.

to nickster: you can head into details here...hehehe

extreme: i usually dont run with kits, i think more can be done with a custom set up and even if something i buy was a kit in the beginning, it never stays that way for long.

a completely different thing but good example, the hitch i just installed. didnt read the directions and it wasnt made to fit a dualed out ranger so i had to mod the brackets and mount them backwards, then adjust the hitch to a different reccomended width then suggested for my truck (i went with the reese adjustable) ive already pulled some weighty trailers and alls well.

wut all do i need to do to get my engine to be able to withstand a supercharger with, say, 8 lbs of boost. would new heads do it?

find the body and head of a 4.0 supercharger on a blown motor and buy it for 500 cash from the owner...there's a beginning of a cheap kit

This kit will run about 5.5-6 psi factory and right now im makin about 9.5-10psi with my kit. very efficiently and the fuel mileage is around 17-19mpg

^^^wut all have you done to it and if you dont mind my asking, how much more money has been put into it? i dont think 4 grand on a supercharger alone is worth it. especially when its only rated at 74 horses.

persuade me as to why this would be better then buying a centrifical 'charger and intercooler set up?

HOw did U manage to intercool the EE kit? IN talking to them, etc. they said that there wasn't enough underhood room to run a setup similar to the Lightnings and the Cobras. I mean I know they use an intercooler as part of the intake manifold (directly under the S/C) and a heat exchanger in the lower valance. An intercooler setup on a Roots/Lysholm/Twin screw setup is much different in the way it is routed than on a centrifigal (Paxton, etc.) setup.

I know that I want to intercool mine once I drop the kit on it, but I haven't figured out how.

You can IM me the details if you don't want to tell everyone your secrets. j/k

Not trying to jack the thread but if you guys are looking for a centrifugal type supercharger, I have a custom kit for sale. Its intercooled.
