i recently got into a debate with my buddy over s/c vs. n/a

this is what it boiled down to:

s/c pros (centrifugal, i.e. procharger, vortech)
-great drivability
-more hp per dollar spent ratio
-choose to add more hp with a pulley and tune
-cool sound (intimidator factor)
-available self contained oil system (no tapping oil pan, procharger)

s/c cons
-boost on a stock bottom end
-boost with a high compression engine not the best way
-chicks ask what is wrong with the engine

n/a pros
-sounds badass with cam and full exhaust
-increase rpms
-your defeated opponent cant throw the "you only won because you have a supercharger" excuse
-more torque (than cetrifugal not roots style)
-h/c/i packages is what vettes were made for
-chicks dig it

n/a cons
-drivability goes down with gas mileage (depending how big of cam of course)
-putting the power to the ground can be a pain in the ass

here are a dyno of one LS2 w/ a supercharger and one n/a



help us out with any pros or cons you guys have for either

i personally am going the n/a route even though it will be more expensive and less hp.

You can still have a sweet sounding cam AND a supercharger. Best of both worlds. :D I'm struggling with the same dilema. :lookinup:

Build a solid\reliable N/A motor with high HP and slap a SC (low PSI) on it and forget about it.

Best of both worlds - I think...??

While my car is not in the Super High HP class it is very drivable. Around town milage dropped by 3mpg after adding almost 200hp. Amazing I am still getting between 28 and 29 mpg on the road.

I think what you are going to use your car for will determine your path. If you are a drag racer SC/Turbo has the most potential. If you are a road racer SC is problematic and few SC cars perfrom well at the track from my observation. They deal with more heatm, a narrower power band and power surges. If you want FI and road race, turbos are a better option, IMO. If you are a Cruiser/Show person the SC has more bling and post great dyno numbers. My 500rwhp pales next the numbers I have seen from a Forged 403 with a Maggie. Go with a "blower" cam to get the most out of your SC motor.

I like the responsivness of the NA motor. I was considering a Maggie when I went for the 403.

:cheers:

like i said i know that i what i am doing (going n/a) .....i also have a feeling that the n/a dyno car would beat the s/c dyno car or be neck and neck. which would not be bad considering the 25 rwhp he will have

and yes i could do both but as i stated in another thread...i come from mustangs and everyone i owned was supercharged, mainly because it is a pain in the ass on mod motors to go n/a

i feel with 500 + at the wheels i will be more than satisfied and beat about 95% of the cars i come across at the same time running 11's which is plenty fast for me

One Man's Reason For Both

My goal was to get into the 9's shifting through the gears ,that's why I went with both.
To do 9's with a N/A motor it would have to be pretty radical, (ex high compression, huge cam, 3.73 or higher gears), a big sacrifice in drivability ( high idle, very lumpy cam ). It's power band would need to be about 4000 - 7500 rpm. Gas mileage would go out the window, especially if you have an automatic trans because you would need a high stall.

With 720 RWHP and almost 700 RWTQ on tap I get 24-28 mpg on the highway. A N/A car with 720 RWHP would get about 8-10 mpg if your lucky.
With what I have , if I can hook it up ,9's should not be a problem.
I'm waiting for the billet Alum or cast steel differential case to come out to make the rear bullet proof when I launch hard with full slicks. Now it's just R6's for traction.

:cheers:

Yep, After I get my S/C installed the rear will be my worry also. :agree:

well you definitely wont be wasting anyones time going 9's but the sad thing is there will still someone you will come across that will be faster....and as i said earlier i will be plenty happy beating 95% of what i come across while saving $10k

but i also wont have the privilege to say i run 9's

best of luck of hitting your goal

Thanks POACHR

I know there will always be a faster car. You can take that to the bank.
I'm not trying to be the fastest nor do I street race for money, I'm just like you but I want to beat 99% of the cars that F with me. :D

What year Vette do you have. Do you have any pics.
