Superchargers, which are better?

energiesource · April 25th, 2007, 12:52 AM

Is there a difference between the ones that bolt directly onto the manifold compared to the centrifugal ones that basically mount to the throttle body
ex a kb over a paxton novi

White99stang · April 25th, 2007, 12:56 AM

KB great for the street, centrifical great for the track.

energiesource · April 25th, 2007, 12:57 AM

This may seem stupid but do you need an intercooler for all supercharger setups, or just after a certain psi or what?

White99stang · April 25th, 2007, 12:59 AM

a intercooler is good for any supercharger, its not needed really for something with low boost but it just helps you make more power of course cause lower intake temps mean you can add more timing and make more power.

ChrisJ · April 25th, 2007, 01:21 AM

I really like my Vortech T-trim...

I have an intercooler for it but it is sitting in my bedroom...

Paxton is the best Centri though...Thats an opinion though...

KB's rock as well...They are insane...

I hope this thread doesn't go like the other ones on this subject. LOL

DrHolliday · April 25th, 2007, 01:29 AM

I just installed a KB on my car. I love the hell out of it. The power really is from idle up. But I need to start looking for a dyno soon....

Why are Paxtons better in your opinion?

jivepepper · April 25th, 2007, 03:39 AM

I'm bias, but I think the Vortech S series is the best bang for the buck.

Will support from 340-600 rwhp on a pi 4.6l. Lowest start up cost, with good reliability.

matrixpuba · April 25th, 2007, 04:48 AM

PROCHARGER FTW lol
an intercooler lowers intake temps which will alow you to run more timing.

Build your own intercooler for 400 dollars. Show me one p1sc on a 2v making 600rwhp. Hell its hard to find a p1sc breaking 500 on a 2v. My first SC set up was less than 3200 dollars on the car and running, Thats all new parts.

zkid01 · April 25th, 2007, 07:51 AM

And here we go again...

SWEET2KSTANG · April 25th, 2007, 08:11 AM

i am a procharger fan. lowest boost temps, self contained, very very efficient, and etc. the dead units are great but you will have to get the one that will suit your needs.

just go with a d series
they are closer to the same cfm of the paxton 2000

My thoughts exactly. (See my post above

I have been looking into this as well, and have found that the kb isn't good for the 1/4 might be a little out dated. There seem to be quit a few guys running sub 9 sec 1/4 miles with them now and some of the centi guys are switching over to them without regret.

Here is a link to a 27 page post on the subject, and in the end it seems the kb cars using the new design (non autorotor) are able to run the 1/4 just as well as the centri style chargers and are doing it with stable air charge temps

n8sv8 · April 25th, 2007, 01:33 PM

The superchargers that bolt directly to the manifold are "positive displacement" superchargers and are either Roots (paddle style) or a twin screw type (self explanitory). The positive dis placement blowers move a specific amount of air per revolution (ie a KB 1.7 will move 1700cfm per full rotation) and allow for instant "full" boost from ~2000 rpm. These type of blowers make driving your car fun and it truely behaves like a big block.

The centrifugal type have an impeller much like a turbo and rely on engine RPM to gradually build boost over the full range of RPM's. It makes for smooth power delivery with emphasis on the top end. Generally centrifugal cars will have a higher peak hp number with lower torque numbers.

As far as which is faster in the 1/4... I'd say it depends heavily on the car setup and driver capability. IMO turbo's PWN all on the track!

Baneful · April 25th, 2007, 02:29 PM

Just curious, but how many cenrifugal 2v cars here are pushing 900+ hp to the rear wheels?

White99stang · April 25th, 2007, 02:51 PM

the question is how many centrifical cars that are making less power are running faster than the kb cars, answer is almost all of them.

Baneful · April 25th, 2007, 03:05 PM

So the 2v cars mph is putting the 2.8 kb and running low 9s wouldn't hold their own vs say a novi 2k or pc f1 using the same block?

Not trying to start any kind of argument. I'm mainly asking because when I get a sc next year I want toget the one that will work the best.
