thanks!

My piggy back system is an SMT-6 from Perfect Power in South Africa. Have a look at http://www.perfectpower.com

I didn't see if the SMT-6 had an input for that... It would be nice to have a mechanical reading of that just in case.

I am running without a knock sensor. Windows up and everything off when tuning. I could well be missing some very light detonation, but, generally it is dead easy to hear and get your foot out. I expect it easier to tune withOUT the SMT-6 and you would get into detonation less frequently than I have during tuning...regardless our engines are pretty solid. My car has 270,000km on it.

Comfortable with my tuning at 7 psi, I put the 10 psi spring in the waste gate this morning before driving to the office. The re-tuning (slight adjustments) are not yet complete but I can report that there is zero lag, combined simply with great thrust and it's quiet!

Todd, has been telling me that when dialed in at 10 psi I will have added 100 hp at the wheels. I believe him!

I am now focused on getting the car ready for a driving school at Shannonville Friday the 20th and won't get to the dyno until after that.

Curious about your set up...you mentioned you installed the necessary MAF...why is adding a MAF versus stock AFM necessary for a turbo install...aside from its programability? Second, you mentioned that you are playing with your A/F and timing retard. What kind of device have you added to the motor that gives you the lattitude to supercede both A/F and ignition timing of your Motronic engine management...aside from changing your EPROM?
Congrats.

Hi,

can i just ask a blunt question?

why fix something that isnt broken?

i dont know of a better sports sedan EVER manufactured ...

i may sound bias but, is there really?

agreed age is catching up on the E34's but as we all know there are thousands of great examples around..... BMW have never made a better model or am i just biased?

i believe the model is a motoring icon... in years to come the e34 will be regarded as one of the classic motorcars along with (in my opinion) the T model ford, the E type Jag, the 911 carrrera etc etc, and lets not forget mercs...

the only thing i have found (my opinion) that is a worthy "performance" upgrade to E34's is a perfromance chip...(lets face it computer technology is far beyond E34 manufacturing dates) and greater flow air intake valve...... ( we all like a good suck

E34's are a motoring icon

Steve, if I might jump in...if the 535i was 'perfect' and not to be improved upon, why did BMW build the 540? Or, an even better question, the M5?

I guess all I'm saying is that I am of the camp that feels there's always a tweak to make, always a weak spot to address, always one area that can be improved on, even in a great car like the ones we drive. A turbo is a neat way to enhance the power output of the 535i, a car that has now been surpassed from a power/acceleration standpoint by modern minivans and Accords.

Is power everything? No, of course not! But if you can enhance that area, and are willing to spend the time and $$ needed to do so, why not? Seems like a great way to keep a classic in the ballgame against modern competition, and it gives people that like to tinker something to tinker with. We all know some of us would be bored to tears with a 'perfect' car that didn't need our attention once in a while.

I agree with you on the fact that these are some of the best all-round cars ever made, and for that reason, plenty of E34 owners keep their cars in pristine stock condition. This is my choice too (well, I try), but that doesn't mean I wouldn't enjoy driving a blown 535.

As long as there are cars, there will be people to alter them in ways the manufacturer did not intend.

Good to see that we are all different....I happen to love having the car stand up on it's hind legs and whoosh off to the rev limiter. Safely! And, the E34 chassis is absolutely ready.

hi , you are right i do have 300hp already and i take your point... i wouldnt mind driving one either (heavily modified E34), but owning would be another story... i had a 525 and a 535 before and wanted a bit more power so hunted down a good example of a stock 540. i dont think we have the scope for "improvements" like the owners do in the states...

and yes many vehicles get altered in ways the makers didnt intend...
