Remind me again what it is about the centri you like Dave? The power has to spool up so it comes in the upper RPM band which is ok for racing but not street driving. I personally want that power right then as fast as possible...

 

Well fellas I'm turning in for the night I have to be at work at 7:00 am as usual so I otta get my beauty sleep!

 

Sorry doesnt look that heavy to me I also dont think it looks cramped... I think it looks like it was made to go there... opinion of course... lets start a Twin screw bashing thread. I could also debate on the price of the twin screw...way overpriced... and it sits on top.... dont want to run my shaker on top of a twin screw...just wouldnt look right

 

Well I have to say they are a bit cheaper. They were like 1000 cheaper a few month back but it seems that everyone has jacked up the prices lately. So now I really don't know. I figure no matter what its gonna be bad a$$ !! If money weren't a concern I would go with a whipple or saleen.

 

Each to their own man...that's the beauty of building a car...good night kids...

 

Jeff I like twin screws but love the centris better... I understand your opinion of them.. you dont like them. Now lets stop talking about the downsides to them, because there is always a different side. I like the fact that they have a turbo type action to them... staying out of boost at lower rpms is fine with me.... also most centris kick in at around 2700rpm if I am correct and run strong to redline. Its a different type of power adder that a lot of people enjoy. Yes twin screws get into boost quicker, but they are expensive... centris are cheaper and are more of what I am looking for... I dont race on the street Jeff

 

More talk later Must get sleep now........

 

So when I get my centri I expect that the centri bashing will stop... And your right to each their own. But thats kindof like saying hey thats shirt looks heavy on you and isnt flattering and makes you look fat, I like a lighter shirt makes more sense and makes me look skinny but "to each his own" no biggie just food for thought

 

Man you go to sleep early D!!

 

Hey David.. I am actually thinking of going the Turbo route as well like Paul is suggesting... I love the fact that you can control boost!! Oh and the blow off valve is pretty sweet too Plus it works with my shaker

 

I found this from Chuckles on Modfords... says the centri is actually lighter than most no more fat jokes haha

. Twin Screw pros:
a. Mild mannered, easy to drive fast, very predictable, linear power curve
b. Quieter in non-boost situations
c. Huge low end torque (400 ft-lbs at 2800RPM) no need for lower gears and lower MPG
d. More usable power on the street due to torque and linear power curve. On 90% of my "Street Races" the other person gives up in the first 100 ft because I "Frog hop" them sooooo Bad. I usually start at 2000 RPM in second gear and the race is over by 5500 in second!!! I never have to go over 75 MPH!!
e. Easy to install and maintain. ONE belt and oil change every 50K miles.

2. Twin Screw Cons:
a. Expensive 4-6K for basic setup
b. heavy. Adds 50-60 lbs to front end of car.
c. Harder on driveline components. Huge low end torque is a bit more stressful on stock components.
d. Hotter. Engine will suffer a bit from "heat Soak" due to extra metal casing from S/C
e. Less MPG. Expect 1-2mpg less overall.
f. Limited High HP potential. (There the law of diminishing returns)
g. "Seem" slower because of very smooth, linear power delivery.

Centrifugal S/C Pros
a. lighter (smaller components)
b. cooler. (also do to smaller components) Less heat sink
c. Less expensive ( about 3.5 -5.5K for good kit)
e. Higher HP potential. (Centi S/C is basically a belt driven Turbo)
f. Get a "Rush" when the power comes on

Centrifugal S/C Cons
a. very troublesome to install. (Many pieces, hoses clamps, fittings, brackets, etc) Look at some of the pics of a Twins screw kit and then look at a Centi kit.
b. higher maintance costs, and time. Lots of fitting, clamps, brackets, etc to get loose.
c. Lack low end torque. Have to "spool up" to get power.
d. Less driveable, more unpredictable power delivery. Harder to control especially in traction limited invironments. A twin screw with good tires will have better traction even though there is more torque because the power delivery is even and controlled, not "on -off" like a centi, or a turbo.
e. Noisy. (All around the loudest of all three discussed here)

Turbo Pros:

a. Cooler (turbo is not doing much when not in boost
b. better MPG (no parasitic draw when not in use)
c. Very high HP potential (U can really turn up the boost on these!)
d. Quiet, even in boost they are very quite
e. Driveability is good. They do have some of the on-off like a Centi S/C but can be controlled easier with boost controllers.
f. Not as hard on engine, driveline components.


Turbo Cons:
a. heavy. Usually as much as twin screw because of all the plumbing/piping involved
b. very troublesome/time consuming to install
c. Also more maintenance hungry. (pipes fittings, hoses etc)
d. No torque down low. (have to spool up).
e. Expensive. Good turbo kits are 6-8K
f. harder to tune

So there you have it. Basically it really boils down to what you want to use the car for. If you want a fire breating 1/4 mile beast, get a Centi S/C, you'll get the most bang for the buck, but loose streetability, and will work on it much more. If you want quiet, super High HP, best MPG, then get a turbo. If you want a "street killa" that will kick most people in the ditch and still provide good daily "Stock like" driveability, and be the most maitenance friendly, get a twinscrew!! I've owned turbo cars before, and I'll tell you, the twin screw is the best fit for all around daily street use with the occasional 1/4 mile jaunt. I wouldn't have anything else.

 

THis is all info from a non biased 3rd party... Love the pros of the twin screw and would love to have one do to all of the pros it has... but again I am stuck with my shaker hood that I absolutely wouldnt trade...well maybe if I got a sweet hood!! haha anyways... turbo would be my second choice, but they are expensive!! so it looks like the centri is my best bet... has high HP potential but is a bit unpredictable under boost, I would love to just turn a **** on a turbo and up the power

 

Jarrod i know you prolly won't ever get rid of it but if you ever wanna get rid of ur shaker hood let me know---I've been looking at them . I just need to save up some $$ but pretty freaking expensive brand new..$750 ishh

 

haha Zesy.... dont think I will let this baby go love it!! But if for some reason I ever decide to go with a KB and have to get rid of the shaker...you will be the first to know

 

Good info Jarrod. I agree 100%

I am still debating on which to go with. If the prices keep getting higher for the centi units I may go Whipple, KB or Saleen. If the price is only a couple hundred more.???

 

I'm still decided on the KB or turbo setup... just for the record... Jeff stoled my KB idea. COPY CAT!

 

I think I may just go with a KB with a centri and turbo setup with a 100 shot of giggle juice. I think that should do the trick to keep everyone happy.

 

OK, just got a second. I teach summer school in the mornings and have been doing basketball camp afternoons. What the heck was I thinking? Anyway these are my mods guys. JBA long tubes, pipes off road h pipe, pipes high flow cats, borla mufflers, steeda underdrives, c&l intake(street) sct with Curtis' tune. Did have the Brenspeed and really liked it but lost it do to Curtis'. The rest of the mods I have are cosmetic . Like shakerhood scoop, hurst shifter, louvers, billet grill, deep dish 9 inch on front 10 on back etc...

 

Oh yeah, I think it was Jarrod that was talking about the clear lenses. I have them and the side markers and love the look against the black. On that sweet Grabber Orange I think the smoke would be killer. Also David That sucks with the run around they are giving you. I dont mean to rub salt in a wound but just have to share this because for once I caught a break. I called my local Ford dealer yesterday to price and order new front 02's. After taking all my info he asked if my car was not still under warranty I told him it was but had mods done to it. He said dont say anything just take out the 02's and bring them in and he would write up a ticket. How cool is that? Anyway maybe this will be the fix i am looking for. Gotta go the basketball court is calling.

 

Kenny... are you talking about O2 sensors? If so. Cool.
