Edelbrock SC vs Whipple?

That is the dumbest reason I've ever heard for not buying the Whipple, but it's also freaking hilarious!

Not even close.

The lower the intake charge temp, the denser it will be, and make considerably more power at the same boost.

You also need to understand that the Eforce and Magna are not "PD" blowers.

The Whipple, KB and Lysholm are PD blowers.

just ordered my WHIPPLE. will i need a IAT relocation? has anyone been having problems blowing fuses on the MSD? also will a CAI fit without any modifications on my whipple blower setup?
Thanks for all the help C5

LOL! I know but the mere mention of the name Whipple makes my sphincter tighten.

You do realize that "PD" stands for "positive displacement" and, yes, roots blowers such as Edelbrock's E-Force and Magnuson Products' Magnacharger are, in fact, "PD" superchargers.

You need to do your homework before making a comment like that.
All Roots/Magna blowers are NOT Positive Displacement blowers.

[Good2go]

So, what defines a PD blower?

Inquiring noobs (like me) want to know...

How about following your own advice. Please show me ONE, JUST ONE roots / Magnacharger that is NOT positive displacement.

From Magnuson, makers of the roots-style Magnacharger,

"This is because the hybrid-roots style supercharger is a Positive Displacement Blower and moves its volume in air with each revolution – no matter what speed it spins at."

http://magnacharger.wordpress.com/20...finitive-test/

"A Magna Charger, Inc./Eaton supercharger is a hybrid roots design and a positive displacement pump."

http://www.magnacharger.com/faq.htm

From Eaton,

"Eaton manufactures highly engineered, roots-type positive displacement superchargers."

http://www.eaton.com/EatonCom/Produc...Superchargers/

"Eaton designs and manufactures precision Roots-type positive displacement superchargers for highly specific automotive applications."

http://www.eaton.com/Eaton/ProductsS...gers/index.htm

This pretty much sums up why twin-screw compressors and roots "blowers" are, by definition, positive displacement superchargers:

"This is because the hybrid-roots style supercharger is a Positive Displacement Blower and moves its volume in air with each revolution – no matter what speed it spins at. Centrifugals, on the other hand, have to “spool up” like a turbo and have an output that increases with rotational speed giving the centrifugal its “peaky” powerband."

Is that enough "homework" for ya?

Apologies

The distinction I was trying to make was between the Roots crowd (Magna/Eforce) and a Twin Screw. (Whipple/KB/Lysholm)
The Roots are "merely" air pumps (no pressure/boost inside the case housing the rotors)
The twin screw compresses the air (boost - my definition of PD) between the rotors (inside the case) which results in higher efficency
Which is why I refuted the statement which said that boost for boost "All PD blowers would make the same HP"

Really? The whine is the sexiest sound of all ... and VERY intimidating to other drivers who are thinking of taking you on ... especially those hiroshima screamers with their stupid "ppppfffffffffffttttttttttt" sound between gear changes.

[QUOTE=10aSSee D;2940321]All the PD blowers are going to have close to the same horsepower and torque granted they are running the same boost. This statement is 100% not true and if it was we would all just buy whatever blower is the cheapest. A bigger or more effecient blower makes more power per lb of boost because of many reasons. 1 is the blower is turning at a lower RPM. A blower that turns slower doesnt generate as much heat thus decreasing IAT's creating more power through tuning. 2 The bigger blower is moving more air. More air means more power potential. All of these aspects are if the cooling systems are equal and If the cooling system is better and more effecient than another then it too will make more power. Then there is the debate of roots TVS vs twin screw. I will not get into that one but it is of my opinion that a twin screw blower is more effecient than a roots and as a result make more power per lb of boost. If all superchargers and turbos were equal and made the same hp per lb of boost then there would be no market for them and we would not have such a hard time choosing 1.

Anyone who is still a skeptical noob can just do a search and you will find mounds of data on this issue. KB for instance makes bigger more effecient blowers constantly and test them against their old ones which reveal that the bigger blower is making more power per lb of boost. Case in point closer to home is in GMHTP MAY 11 issue. Redline Motorsports added a KB 2.8 to a 10 SS. Its pre KB combination was a Magnuson powered and built LS3 7.0 producing 14-15psi and it made 712RWHP. After bolting the KB on and getting the boost to the same psi it pumped out 796RWHP and 750lbs tq. Are you going to see 84RWHP difference between the TVS 2300 and KB 2.8 or Whipple 2.9 at the same boost level on a stock motor? no, but 40+RWHP is totally possible.

Granted this has been a thread about which is better than the other. This has been the most informative thread i've read so far between the two SC's. I'm been in a dilemma trying to figure out which direction to go when and if i purchase a SS. The plan in itself is to SC it right off the bat, well... maybe enjoy it for a bit stock and then later SC it. I have the cash now to purchase the SC and small supporting mods to give the car ~530whp. But i think if i was smart i would just put that cash down on the car to get lower principle value and lower payments, lol. Any who seems like the E-force will be more than plenty for me and keep me quite happy for the weekend warrior street car. Keep posting guys, this has been very interesting read.

idk if its true or not but a friend of mine at hennesey adviced me not to go w the whipple since its to powerful for the stock engine and could be inconsistent at times if you want to go with the whipple your going to have to build it quite a bit for it to be a consistent and keep your engine safe ipaintbridges did the right thing and got the custom blower cam which makes more power at the crank securing it more... i personally on the hunt for a supercharger myself and so far im thinking bout the either the whipple or the tvs
