Kenne bell vs. centrifugal vs. Turbo

Twin turbo V8 Mustangs are virtually untouchable.
on the Supercharger side though ever think about whimple??

Garhfer · June 15th, 2007, 04:46 PM

lol, I think you pretty much spelled what it is! lol whimple, I think you mean whipple... it's basically the same as the kb it's a twin screw

droppedbass87 · June 15th, 2007, 07:37 PM

yeah well you have to do all the kmember swapping and stuff with turbos but afterwards you will be one of the baddest guys around your neighbor hood..just imagineg going to a car meet with a bunch of ricers and then rev that sonbitch up and all they here is wssssssssssss from the bov..they will be like omg what the hell...personally im thinking a procharger d series or a kenne bell 2.2 but thats 5000 for that 2.2.....i dont know what to go with??

noob · June 15th, 2007, 07:42 PM

personally my votes for kb, you've got to love that whine

droppedbass87 · June 15th, 2007, 07:43 PM

nope the new ones dont whine anymore like the old ones...i liked it to cuz people can actually hear what you have

noob · June 15th, 2007, 07:46 PM

ohh that don't, well thats shit. so there silent now, wheres the fun in that.

SWEET2KSTANG · June 15th, 2007, 08:47 PM

they arent completly silent. just turn up the boost to see how loud they will get. the bigger units arent as loud anymore since they arent getting turning as much to make 10psi. take that same unit to 18psi and it will change.

noob · June 15th, 2007, 09:05 PM

oohh i see.

Badasstang281 · June 15th, 2007, 11:23 PM

What do you think the hp would be with stock internals and a 2.6l at 8 psi. would it be over 450hp??????

Drgnracin72 · June 16th, 2007, 12:30 AM

cantri and turbo cars make for faster cars. twin screw blower imo is just a badaid for low comrpession. have you ever driven a turbo mustang, yeah theres some lag, but from 800 rpms to 3400 rpms, how long does that take, a split second way better off with the turbos or the centri, and centris are fairly easy to install turbos being the most difficult and twin screw being the easiest. id go centri or turbo if i were you

I'll have to see if mine drops off when I up it to 14 psi. But my build still won't take me past 6,200 rpms so I still might be too low to see a drop off.

you know kb says that you should not spin past 6000 rpm with their blower. it will over spin it andwear down the bearings faster

auburntiger7231 · June 16th, 2007, 12:44 AM

you'd rather go kb than twin turbo'd are you crazy? Twin Turbos have a lot more potential

+1 on that. For shear all out balls to the wall POWAH!!!!! Go twin turbo baby!!!! I want a KB so bad I can't stand it but given the option of TT and KB(if $ was unlimited) I would, without a doubt, go TT.

SWEET2KSTANG · June 16th, 2007, 02:15 AM

and not to mention, a 2.6 at 8psi is worthless! you can utilize a 2.1 at 8psi better. it takes more power to turn a bigger blower, or turbo. the larger set ups are to make big boost at lower temps than what a little one can make at higher boost. you can go over board with set ups, and you will have to do homework to get exactly what you want. the twin screws are made to turn around 60k before drop off. if you go to small on the pulley and turn the screws more than the rated 60k or what ever they are set then there the drop off issue.

MustangMatt96GT · June 16th, 2007, 02:17 AM

I vote the centri or a turbo! It is a proven fact that they will make a slightly quicker car at the track!

That makes me want a KB even more. I love the sleeper appeal to a car. A silent SC is for me.

jivepepper · June 16th, 2007, 08:22 AM

Centrifuge Superchargers lag worse than turbos I don't see full boost until redline. Thats why turbos produce more torque than a centrifuge SC. It makes its boost and hp sooner. The sooner you make hp in the rpm band the more torque your car will produce, That's why turbo diesels make big torque because they get it done by 4k. Hp is the measurement of how much power. Torque is how quick in the rpm range the power is produced

Twin screw SC= No lag but not quite as efficient on the top end. That's compared to a equally sized turbo/centrifuge sc running the same amount boost on the same engine set up.

Turbo if the right size is used for the application= very little lag, no belt slip, and very efficient. That equals more hp per pound of boost.

Centrifuge= wait for it but makes great hp for the amount of psi used, but not as efficient as a turbo.

But with that said who races at low rpm?

A centrifuge is still a great way to make good reliable hp. Which is a lot more affordable, and that is the whole point of a mustang. Good performance at a reasonable price.

SWEET2KSTANG · June 16th, 2007, 08:57 AM

but that is also in size of the head unit. if the head unit is to big for the application the lag will be bad. if the head unit is a little smaller the lag will not be anywhere near as bad. it is the same as turbo's, the larger the head unit the more lag.

I honestly think everytime I try to spell it I spell it wrong. I'm just going to kill myself.

Well my S-trim is small and still lags more than a turbo or a twin screw of equal size. Thats with a small pulley which helps with lag.

my vote goes for the KB,if all you want is your power at wot,high rpm,then turbo is the way to go followed by centri.I love my KB on the street because you have much more power at all pedal positions other than wot.giving it half throttle at 2000 rpm in 2nd or third,you see between 2 to 5 psi and puts a smile on your face thats hard to remove.boost is addicting and why only have it at wot and high rpm were you may draw a lot of unneeded attention? this is were I think The KB is the only way to go on the street,it makes every time you drive it an experience without always having to go wot/balls out when you want that put you back in the seat feel. and btw the Kb whine is awsum and very audible when in boost.
