5.7 w/Automatic - supercharger?

[GSMC]

I've never seen anything like it. It seems you can get about any brand you want for the 6.1, but according to the ads, in order to supercharge a 5.7 it needs to be a six speed? - Why?

I see Vortech kits for the 5.7 six speed, the KB's are for 6.1's, the Magnuson is for 6.1's. Only kit I see for the 5.7 auto is a Procharger kit?....am I missing something here? I tried searching and couldn't find out anything.

That's about right. The only supercharger kit for the 5.7 is Procharger. I am talking about kits with tunes. And even their tune is PISS POOR. I have seen several prochargers that ran like **** with the box tune from procharger. They rushed theirs to market while the rest of the vendors are trying to get it right.


Let me tell you it's the tune that's important. Every tuner will tell you that they can tune an RT without a problem. I'll bet you that at least 90% of them can't. The computer programing is much differant in the 2009 5.7 than the others. Hell I will bet you most tuners will tell you that they have even done several just to get you in the door. Then after a few days find themselfves in way over their heads. That's what happened to me.

If you have a good tuner then you can probably get any of the 5.7 kits and get it custom tuned and be fine. There are a lot of tuners that have learned what #'s to put in what table to get a desired result. The problem with the 5.7 is it doesn't work that way. That's why no one is putting out the kits for the 5.7.

Thanks a lot for the reply HemiOrange_RT.

Makes sense to me. I know a little bit about blowers since I have a Magnacharger on a SBC 400 already. So my interest is mainly in the new Magnacharger or KB for the Challenger.

With the 400, I didn't have a computer to try and tune around. It's an old school pre-computer setup. It still took time on the dyno to get it set right.

So -I couldn't agree with you more - the tune will make it, or break it - literally.

Guess I just didn't realize and find it suprising that no one has dialed these 5.7 automatics in yet, since they've been in Chargers and Rams for years, and paying for someone to "custom tune" the car sounds a bit pricey to me since the kits already cost over 4-5K as it is. And what happens if I lose the tune for some reason? Now I have to pay someone again? Guess I'll wait and see what the market will bring.

Your wrong about the 5.7 being around for years. The 2009 5.7 is a completely new engine with the VVT and all. The ECM (computer) has adaptive programing (fuzzy Logic) and is also completely new. They are anything but your old 5.7.

Ahhhh....I forgot about it having VVT. I see where that would make a difference. But the six speed 5.7's have VVT do they not? If they can create a "fuzzy logic" program for that ECM, then one for the auto can't be far behind. Then again, MDS is unique to the automatics....

I have faith though. Someone is going to sort it all out and produce a reliable blower and tune for the auto cars...and whoever does it first will corner the market.

There is also a Whipple kit and there is one on an auto 5.7 right now. Made 545rwhp/591rwtq with 11psi on a stock bottom end.

He also has a custom tune.... The tune that came with the 5.7 whipple kit also sucked and the kit needed mechcanical modifications to even work.

Only one company has a tune for the 5.7 period. auto or 6 spd and thats the Procharger. Like I said in the a previous thread, their tune works ok on some cars but on others it sucks.

Right now if you want a supercharger for a 5.7 you will not only need a custom tune, you will need to find the rare tuner that can do it.

Another example of people talking about stuff they dont know the facts about. The only thing we mechanically modified was the idler pulley bracket, it took about 15 minutes worth of work.

The kit in that video was tuned by me, there was never a tune included that "sucked".

Anyone wanting a Whipple for an auto 5.7, I can send a tune that will work no problem.

Sorry Andy I'm talking about a differant car. The point is there are no good canned supercharger tunes for the 5.7. One vender was offering a tune with the whipple. But the tune was just to get the car started and to a tuner. Therefore a crummy tune. My thought if the tune that came with the SC can't be left in, it is ****.

HORT you need to get off the high horse buddy! You beat your chest like you made the atom bomb!!Andy made way more power then your mild 480rwhp. I am not trying to hurt your feelings but ever since you went to the dyno you post like you wrote the book of knowledge on tuning.
