i have a question about the AA sc kit. i know that the rotrex sc is pretty much maxed out at 5.5 psi, but in the future is there gonna be a way to upgrade the sc to something with more boost. i know someone is running i think around 7.5psi. is he using a completely different sc unit? is there a way to get more boost?

i know rennsport is working on an SC kit and I was told that it will be a lot cheaper than most kits out there. if theyre using an ASA sc, then are those upgradeable by the use of a pulley?

i just want to know what my options are for the forced induction. thanks everyone.

your options right now are to go with a rotrex C unit that currently is reaching its max CFM/PSI limitations. The Vortech units that i believe evosport is using and Discovery auto are going to use are good depending on the build up of the engine to around 20psi.

As for ASA and ESS...dont know

AA's kit is running 6.5 psi. You can get higher boost if you want, but they won't warranty it.

I believe you can up boost on the AA kit to 7.5 - 8.0 psi safely. Beyond that with this kit, it's just asking for trouble.

sorry to hijack the thread..but the stock s/c's in the E55/S55 AMg, does anyone know what PSI they run on stock?

According to MB, boost is set at 11.6 psi max.

The SLK32 AMG I owned pushed out 14.5psi stock.

Isn't the Evo-sport kit using a Pro-charger instead of Vortech. Ess is using a Vortech V2SQ. I don't know about ASA. I've seen some of their SC's on ESS Tuned cars though.

^^ correct, they are using a procharger.

MB can run higher psi because their cars such as the E55 is running a compression ration of 9.0 versus the M3's 11.5. Lower compression=Higher boost. I wouldn’t mess with a SC higher than 7.5 psi in the M3 engine. Maybe a little higher with some water injection but that is still asking for a problem.

Ok... When going FI lowering the compression is the easiest thing to do... Just get a thicker gasket and its done.

I doubt there will be any Supercharger options in the market place that are much cheaper than the AA if for no other reason then people will pay. The Rotrex unit AA uses is notorious for producing excessive amounts of heat and that doesn't fit well with longevity.

from what i know of the rotrex unit, its not that it produces that much heat but its the ability of the casing to get rid of heat soak from being in the engine bay as well as its own produced heat that causes some issues with track work for it.

Dinan S/C with aftercooler 475 hp. It's around 10k...

Last I heard, the 420 HP version would be in the $12K range before installation..and the 475 version closer to $18-20k before installation.

8500.00 for the 420 non aftercooled.

10k for the 475 hp aftercooled. About 6 labor hours to install. Kit should be available by now.

You should try out the Dinan.

RMS was the expensive one.

Hello 04tytaniumsylvr,

I am really waiting for the Dinan SC for my 04 M3.You have any idea when this thing will be released? Was the price range you mentioned just a rough idea or concrete? I heard the release date would be in June 2005 sometime?

Thanks in advance!

Would you be able to put a head gasket on to lower compression? I know some other cars do that such as the IS300 kits. Has anyone put the head gasket on?

How sure are you about those dinan prices?

Strangely enough I haven't ever heard this option discussed for our cars. There might be clearance or complexity issues with that type of *cheap* compression mod.

The last I heard both versions of the Dinan S/C were going to be available in either Jan. or Feb. 2005, but I was told that in late Nov. I was also told $9k for the 420hp and $12k for 475hp. I guess we wont know until the actual release what the final price or hp is going to be. The Dinan website says that the performance numbers they list are preliminary and may change before it is released. I was thinking of contacting Eric at Dinan on Monday.

Who ever asked about the MB E55/S55 superchargers, you must also remember they are bi-supercharghed.

the prob with sipmly changing the girth of the headgasket is the the decrease in CR will not drop significantly. to take the CR from 11.5 to 9 by simply using a thicker head gasket is ridiculous. thet woul become the weakponit in the motor and you woud start blowing them.

i now evosprt is overpriced, but if you really think about it, it is the best deal out there. you get what you pay for.
