Well SVT-SiNiSTER what is it going to be?

 

Crash!

Put me down for one of those, when I get my Mustang.

 

Dave,

Do you ever respond to someone without being a smartass about it?

That being said, I did not know there was a restriction on the size and type of supercharger. I know the engines are limited to 500 cubic inches, so perhaps I should have realized there would be a limit on the SC.

Here's a better question for you:
If the centrifugal supercharger were superior in every way, why would anyone keep making roots and screw type superchargers?

I really do not care what your answer is. I don't think there is a single thread in this forum that doesn't end being "my supercharger is better than your supercharger so phbbbbt!"

In this thread (and in fact every time it comes up) I try to present a balanced overview of the advantadges and disadvantadges of each type of supercharger. If someone is really pushing the advantadges of one unit, I will sometimes offer reasons to use another unit.

The goal here should be to provide people with as much information as possible so that they can make their own decisions.

There are a couple of people who are leaning towards the KB.

How about this-

KB or Magnacharger (now Allen Engine Development kit)

My vote goes to the AED-

A. smaller blower(1.5L) uses smaller rotors

1. less parasitic loss
2. full boost sooner
3. better throttle response

B. intercooled

C. safer fuel delivery with intank pump

The kit is limited on the 5.4L


KB use to supply a smaller 1.5L compressor, but customers wanted more boost so the increase was to the 2.2L for the 5.4L and 2.0L for the 4.6L.

A chip is included and apparently larger injectors are included rather than the FMU. A step in the right direction.

 

Crash,

I installed a second IAT sensor in the manifold to measure the charge temp under max boost - very easy mod. Drilled a hole with interference fit with the sensor. Under 10# boost on an 85 degree day, the highest the temperature went was 122 degrees. Where did you get the 160-180 deg. temps from?

 

Crash,


What about the turbo kit, any updates? that is where the serious power will be at. If need be it can be set to spool up quick for any towing needs.

 

sorry you took it that way Don, when i found out a while back that that was the rule i was blown away, i thought top fuel was run what ya brung.


i dont think anyone said they are superior in every way, i think the idea was not to be close minded about the different types meeting your needs. which i still think that either profide a nice gain over stock.

i have answered all your questions and i even provided a quick vortec truck that you may or may not have seen and i showed you why certain blowered are not allowed in top fuel. did i have a little attitude, yes, didnt start out that way.

i actually own a s/c and i have been very honest of my likes and dislikes,
i still think IRONHORSE gave the best advice anyone here has provided about people being very pro whatever they have.
my biggest pros of
my vortec is this, extremely quiet, reliable, low maintenance, and i know i am not going to blow out my trans and rear end with of the line tire shreading torque. passing someone at 30 or 60 moph is an absolute kick in the a$$. if i wanted to tow then i would get a set of 4.10's. good reputation for reliabilty and customer service.

biggest cons, affected by the weather, lowend could be better
(see add 4.10's) pings in above 90 weather. (no chip)

 

That is exactly what it comes across as. Every time this topic comes up, someone starts off on how they should be running a centrifugal supercharger. It does not matter what the application is, it does not matter what truck or what engine.
I have run turbos, centrifugal, roots, and screw type superchargers. Each has its nice points. I have always provided an overview of the pros and cons of each one. If someone were asking for all out top-end, I would recommend a centrifugal supercharger in a heart beat.

I have never seen you or Crash recommend _anything_ but a centrifugal supercharger. I have recommended all of them.
I have said this in _every_ post I have made about superchargers. I have always said that there are pros and cons to each type. I have said the people should look at their needs and decide what works best for them. I have no idea how you could come to the conclusion that I was being close-minded about this.

As an aside, you are basically limited to a 14-71 in top-fuel competition. The containment methods for these superchargers has gotten insane. Ballistic nylon bags around the supercharger, metal straps, serious bolts all hold the supercharger on. When they blow, it is spectacular.

 

i think that if you use the search feature, you will find that the above is an incorrect statement.

keep in mind that few people have owned both.

 

The only cent I would recommed is the ATI. The others(cents) don't compare. The Powerdyne on my old 4.6L was way too peaky, due to it's curved impeller. Vortech/Paxton use the same type of impeller and of course, as always, no intercooler with their kits.

 

BIGGER!? Not the D-1SC? Which one?
