Supercharger AND Headers?
The folks at Lingenfelter do not recommend Headers when I have my supercharger package installed on my 05 convertable. I understand backpressure, but in this case, I need a little more info. I'd assume I'll need more flow with the increase of air induction. Can anyone explain this to me?

Headers will work great on a supercharged car. However, it's my understanding that Lingenfelter can NOT legally put on long tube headers because it changes the location of the Cat. They could put on a set of shorties, but they wouldn't do that because the OEM manifolds are just as good as shorties.

They're responce
Lingenfelter's responce to my mod request was that headers would not make any performance gains with their supercharger package. They are installing a Corsa Sport cat back only. I'll have to give them a call and get their reasoning.

Engine hp 101... The basic priciple to making more power, get more air and fuel in, and get more exhaust out. If you add a blower to an engine you are forcing air into the engine and through factory headers that were not designed to handle that much flow. Headers are a MUST for a well flowing engine. Your biggest enemy when going S/C is detonation and if you keep the factory headers they do not dispurse heat well plus you have the factory cats butted right up behind them which spells disaster when it comes to detonation. Go with a set of headers!

I'm betting that since legally all they can install are shorties, that's why they are telling you there is no gain. This is true, shorties will not give you hardly any gain in power. On the other hand, I'm betting you pick up over 30 hp with long tubes.

21st Century Muscle Cars (Dallas/Ft Worth) does not have a problem installing headers with the LPE SC Package. I have heard that Lingenfelter (the Headquarters shop) is very reluctant to make any changes to their packages. That's one of the reasons I went with 21st CMC.

sc long tubes yes
turbo long tubes no
The only 2 reason I can think of to go with shorties are lack of space on a build and for legal CA reasons but "the OEM manifolds are just as good as shorties" Not true at all

I have clarified this before, but I will explain once again.
The 112 blower from Magnuson is an excellent street blower to start with, and is designed to work with the stock engine. With the addition of a free flowing long tube header, you will lose a bit of backpressure which in turn will result in a slight loss of boost. Yes it is true, you can spin the supercharger a little faster and exceed the superchargers limitations and peak efficiency with a pulley swap, but this will
void the Magnuson Supercharger warranty, and only show you a very minimal gain in hp.
We do not recommend adding long tube headers to the Magnuson 112 package for the very minimal amount of power gained, while turning the charger harder, creating more heat, making it less efficient, and reducing the superchargers life. This is also a fact with our package while giving you a 3yr/36000 mile warranty on the engine as well as the supercharger. We can talk and explain why we don't recommend this, but this is the package we offer, and why we don't recommend the addition of the LT headers on THIS package. We can talk about the 122 or the Kenne Belle, they are different, and have a different approach.
