E46 330i supercharger questions

Im new to the forums so be easy on me lol ive also been a mechanic for 12 years and i do all the work on my cars. I have a 2001 330i with a vortech supercharger(VF engineering stage 1 kit). I'm looking to upgrade the pulley, put bigger injectors, and intercooler. Any suggestions? I'm also looking for a tune/tuner for that. I have a hex flash which I used to upload the VF tune into my ecu. Is there a way to load another tune once I'm done with the upgrades?

Read through the links. I run an ESS TS and have raised boost by 5 psi, installed larger injectors, larger fuel pump and used the software supplied in those threads to tune

I would first recommend a phone call or Email with "Nik" Saran the owner of VF Engineering, he of course knows what can & can't be done to their VFK 17-01 kit.

Having said that, I'd recommend:

1) A rebuild of your Vortech unit with High Speed bearings & an improved CNC'd High Performance billet impeller. The high speed bearings allow your Vortech to safely spin much faster with your newly installed smaller pulley, and the billet impeller will add 10 to 15% more boost in ALL RPM ranges.

Standard rebuild ~$429
Premium rebuild, with upgraded mechanical seal for the impeller shaft, and ceramic high-speed bearings ~$695
Premium Rebuild with upgraded mechanical seal for the impeller shaft, ceramic high-speed bearings, & CNC'd High Performance Billet Impeller ~$1229

2) Use a water/meth injection kit which will do two very important things:

A) Cooling, running a Before & After W/M nozzle placement will cool the S/C unit plus cool the incoming air charge.

B) Supply an Extra High Octane Fuel supply, this will aid in knock suppression & may allow you to KEEP your current fuel injectors.

3) Smaller pulley for more boost with a granular coating that is applied into the vees of the pulleys, this special coating will prevent belt slippage.

4) Tune: It is possible that the original VF Tune will adapt to these new changes, Nik from VF will can comment on this more.

Thanks for the info man, those are definitely somethings I'll look into. As for VF I contacted them about the upgrades I'm doing and they said they didn't have a tune for the things I'm doing to it. I don't recall talking to Nik but Davew sent those threads and that will probably help me finish everything up. I will try VF again and see if I can get a hold of Nik but i honestly think those threads will help me with the tune. I really appreciate it the helpful tips though!

Did you tune it yourself or did you use the software to have someone else tune it? I'm still trying to understand how the software works.

As far as i know, he did it himself. But hes probably chiming in in short period of time.

What exact problems do you have?

Did you already watch my instructional video on youtube on how to work with TunerPro?

My car/ tuning experience goes back to carbureted V8's and 6's to be completely honest. So tuning a charged E46 was pretty daunting to start with. I first started playing with the software and interfaces (galletto and Inpa cables) until I was confident I had a good grasp of it. I then just made a few smaller changes to get a bit of confidence.

I asked a lot of questions, and the people I asked were very helpful. I first managed to tune the car on the road with datalogging good enough to drive to a local dyno.

I was selective on which dyno I used, I told the operator that I knew the software, but would need a lot of help analysing the data and making finer changes. After a few hours, the car was tuned.

After that first tune, I upgraded the fuel pump, but have now just road tuned it till the next upgrade (fuel pump I tuned it on was too small for injectors, or defective). The next upgrade will be well above my comfort level, so I will be asking for some help remote tuning it.
