Anyone have experience with Supercharging?

Looking to get a SC kit for my 2003 330ci, preferably the ESS twin screw. Does anyone here have experience with these kits? i would like to know if the power gains are very noticeable and how your engines are holding up with the added boost.


Thanks!

You should be concerned about your subframe before sc

Also, go to the forced induction forum.

I was thinking about doing a M3 subframe/LSD swap shortly after.

How do you launch?

Superchargers are definitely noticeable, but not incredibly dramatic since the overall feel of the engine stays about the same. Still easy to drive, still pretty quiet, etc... Just a lot more torque through the same rev range.

It should be before. Not after.

Meh, do your subframe mounting points whenever. It's not like it destroys anything else if it fails. It also is completely separate from a supercharger so it's not like you you can save work or money by doing it at the same time or anything.

Ok right on. Thanks!

I have a 2003 325i with the ts1 kit and 3.46 gears 5mt. I am dead even with my buddies c5 ls1 from a freeway roll. He has pipes and the corvette is close to the same weight as our cars.

Nice! Okay that's what I need to hear. Does anyone know the stock gearing for a 2003 330ci?

I will tell you I blew up my stock clutch very quickly and I never do any dig take offs. It was brand new and lasted 3 weeks after break in. I now have an f1 racing stage 3 and am very happy with it. Ceramic is brutal to break in though.

did you have to do any other modifications along with a Stage 3 kit?

lol yeah right. unless you're running nitrous or he drives like sht.

Dead even. End of story. Also had my front stick to the rear of an audi b7 s4. I'll be swapping an m3 rear in. Nothing else done.

He must have additional work done to his 325 TS1. If both the cars are equal weight, then it has to be the driver of the Vette. At 400hp it's about 360rwhp for the Vette. I know the TS1 on a 325 isn't putting out that kind of power. But there are plenty or variables, so who knows.

Ls1 is 350 crank hp. It's an a4 as well, meaning 15-20% drivetrain loss. So any Ls1 Corvette,gto it doesn't matter, will be lucky to see 300 rwhp stock or with catback. Couple that with 2.73 gears, and the ts1 325i is dead even. The ls2 is 400 crank hp from the factory, the ls6 is 405, ls3 is 430. All crank numbers.

Everyone here is giving sound advice, and I'm not trying to influence your decision, but here's a real-world report for you to help you consider: first thing I did was have the TMS subframe reinforcement kit installed. No other significant mechanical changes (i.e. stock exhaust manifold, stock gearing (2.93?), stock clutch.
I've been running the ESS TS2 kit on my 328Ci for years, as a daily driver. I've put more than 100k miles on the car with the kit installed, and I'm almost hitting 200k miles with the car itself. Haven't done anything special except keep up with regular maintenance at normal intervals. This is the most reliable F/I kit you can buy, in my opinion. Mind you, I don't drive it like an idiot, I very rarely do launches. But I'll still have an Audi S4 or S5 driver know where to stick it if the opportunity presents itself ;-)

The most important thing that hasn't changed: after all those years it still puts a smile on my face whenever I punch it.
