Whats next?

[noBenz]

I've the ESS tx2 sc on the car. ltw flywheel, cerametallic clutch, TSE 3 exhaust.

What next? Headers? Will underdrive pullies help and sc system? FI spec'd cams? I'm looking at getting the header and cams from Tecknic... underdrive pullies from either eurosport, RE or UUC.

Thoughts?

[AS007]

The headers and cams will make a huge difference! The pulleys will help but not much, maybe a few hp.

Definitely headers, guaranteed 8-12 RWHP. Pullies won't help to much IMHO.

Underdrive pullies are a big no no when it comes to a S/C engine. :thumbdwn: I could give you a long explaination, but it is better for you to go to this link http://e46psi.com/forum/viewtopic.php?t=8 and look at some pics with your own eyes. If for some reason you can't open the thread, go to e46psi.com then go to the Active Autowerke forum and look for "AA SC and UDP: A big NO NO". I know you don't have an AA kit but the basics should be the same.
I would go with the headers, high flow cats. Super Sprint has a system that would be great but it is $$$$$$:omg: Another mod you might want to save your money for, is Limited Slip Diff. As you probably know by now, it is hard to put our new found power to the ground. By installing a LSD you will be able to not only take off faster, but most important you will be able to better feel what the car is doing back there.

I have the Technik headers and from there on back I have the Supersprint exhaust system. The car sounds so good and loud, but not too ridiculously loud.:thumbsup:

I don't think UDP will even fit on the car because of clearance issues with I think the compressor or compressor mount or something - can't remember. :(

If you get the Technik headers the next thing would be to get the FI profile cams or get the P&P head to make your exhaust side more breathe-able.

A LSD is a great mod too!:D

[noBenz]

dammit lol thats another 3 G's down the drain

[HighBoostin330]

Yea...SuperSprint costs an arm and a leg, but the whole system to me sounds so good! :drool:

[noBenz]

yea, all I want from supersprint is the header, cams from tecknik and LSD...
By the way who makes an LSD?

[redronin]

^actually Bimgrowl puts together a LSD with a 3.46 diff which he sells for like 2400 if i remember correctly. hit him up.

[Nico3k]

Congrats on the kit! Nice to see more blown 2.5's looking for serious power.

How does the car feel with everything now?
If you had to compare it to the feel of another car, what would it be?

Headers will be a great mod, but I would get some extra resonators installed together with the TSE3; it will sound INSANELY loud (I have heard it in real life). Sounds like an F1 car at WOT.
Also if you don't already have 3.46 gears, they will make your car feel alot faster with the SC.

[HighBoostin330]

Daniel puts together KAAZ LSD for 3.46s. If you want another differential with fully customizable locking characteristic, then I suggest you choose an LSD made by Jim Blanton from Performance Gearing.

Yes it does, but if you have a 5-speed the highway cruising RPM can get a bit annoying.

[noBenz]

Yes it does, but if you have a 5-speed the highway cruising RPM can get a bit annoying.

What do you mean by that? At what RPM do you cruise at on the highway and what speed is equivalent to that RPM range? Yea I definately guess the LSD will be next.
Then headers and cams.

Niko - I haven't driven many FI cars. A couple of turbos but its a different feel. First supercharger and its in a league of its own. Definately faster cars out there, quicker cars... But that SC just makes you grin when it kicks in :evil:

Question though... why does it take so long for boost to start building up... its similar to lag in a turbo right now. around 3500-4000 RPMs is when you can feel the boost take over the engine and the extra "go" come Any way of lowering whn boost builds? I understand the compressor is clutched at 1000-1300 RPMS so whats with it taking so long to start boosting?
Maybe you guys are the wrong people and I should be asking ESS and ASA :shrug:

[AS007]

Centrifugal superchargers are a lot like turbos as far as when boost comes in to have boost at 1300rpm you would need a root style. I think.....:dunno:

Well I have a 6-speed, so that is why I went to a 3.46. Cruising for me is about 3100 RPM at 80mph. In 5th, I am about 3500ish at 80mph.

Regarding why you don't feel the push is because the centri builds boosts linearly according to the engine's RPM. The torque curve on the ASA is pretty flat. However, if you want to start building boost faster and earlier in the RPM, then you need the twin screw. I think it allows for 80%-90% of your torque at about 2-3k RPM and max boost is obtained between those RPMs also. Thus, in a way, it is sort of like a turbo. However, if you notice, the torque number seem to meet at redline between the centri and the twin screw. That is because the boost is roughly the same at redline. I hope that helps. Remember, torque is that power that you feel pushing you.

[noBenz]

Ehh I just guess I have to raise the redline a bit more... to do that I'll go with Tecnik's stiffer valve springs and titanium retainers.
Then put in the forged kit from ESS... should help out a lot
That will be in the distant future though

If you are planning on building the motor with low compression pistons, cranc, rods, etc., you might as well increase the displacement to 3.0L. Then you can take advantage of the research going into the 330. I know Technik has a few options coming out that will involved a new low compression bottom end (turbo, higher boost centrifugal) for the 330 that look interesting and should get you to 400+RWHP. I would expect them to be coming to market in about a year.

[noBenz]

Yes the ESS kit does increase displacement to 3.0. They are at the tail end of testing I believe... Just waiting to hear from them on it.
