For those that have gone from stock S65 to supercharged..

[Rat3d ///M]

..what kit did you go with, and how would you describe the upgrade?

The S65 is an amazing performing machine, but IMHO it would benefit greatly from 100-150 more torque and 150 more hp. Having owned it for almost a year, it's the fastest car I have ever owned, but I am used to the power and would love an upgrade.

I have watched videos of supercharged M3's but it is hard to capture the actual experience of driving one in a video. You can't really get a good idea of how much more powerful they are. Just how much of an upgrade is the VT-595 kit over stock S65? Reason I use that as an example, is on my budget and setup (DCT) that is probably the kit I would go with. Is the difference between stock and VT-595 greater than the difference between 595 and say, 625 (i.e. is it worth it to spend the extra money on the 625 as it's a huge jump or is the 595 good enough?)

How about comparing the 595 setup to much faster stock cars than a stock M3? How does it compare in power delivery and performance to say, the GTR, 911 GT3, Gallardo, C63 AMG?
Anything you can give me on your experience is appreciated.

You didn't want to try a tune and better airflow first? Or do you just want to get a serious kick and not play around with 30-40 more HP?

The jump from stock to a 595 kit is much larger than the jump from 595 to 625. Think about the 595 to 625 jump more like going from:
A: Stock M3
To a -
B: Catless/hfc M3 with a tune

So for $500 (595 compared to 625) it's a small difference in price and decent jump in HP so there isn't any reason really to get a 595 over the 625 since they are both intercooled anyways.

The thrill of revving the car past 5k gets even more intense all the way to redline with a supercharger. I can only describe it as gradually hitting warp speed as you keep climbing.

You have owned your car for about 3 years if I am not correct. Are you still happy with stock power + BPM Stg 2?

It's the BPM/Dev-Tune stage-1 that I have .
Because here in Belgium it's not possible to have the test pipes with the stage 2 , because we need to go to the yearly car inspection and they look also under the car for about 10 minutes and everything not stock is a red card and the car is no longer allowed on public roads !
Also the smoke test would be a fail with test pipes , and actually Belgium really sucks for car mods .
But I need to say that I'm really happy with my BPM-Dev stage 1 tune , power is really good and I had also the BPM-DCT software upgrade , this makes that my car shifts are really fast and smooth .
I've done the DCT software upgrade because I had the second gear lag and my BMW/Dealer was not able to fix it .
But with BPM all this is fixed , and of course the knowledge and customer service of Mike-Benvo is outstanding .
For me personal stock software really sucks and I will keep my BPM/Tune forever .
Thank you .

I went with vf620. They gave me a phenomenal deal, and their kits are easily upgradeable. I absolutely love it, but I had to get a new clutch as well. The stock one did not like the extra power...

I've driven supercharged m3s, had jb4 f80 and I chose a NA catless 2013 m3 and personally don't miss the power. I'm probably a,rarity but I realized I enjoy ringing out the NA,car more than the supercharged or f80 since you get less time to enjoy the experience as your up to speeds that are,crazy too fast. The sheer kick in the pack is fun but gets old and then I was left with less overall enjoyment. Go figure

I sorta feel where you're coming from too

I thought about doing test pipes and tune, and seeing where I am at, but I think I kind of want to go all out and get a no joke power upgrade.

[Bavarian Beast]

I hear the test pipes and exhaust mod are too loud for here anyway.

I'm in the same boat but looking at a 550 kit. If you want an intercooled kit you may as well spend the little bit extra to get the 625 kit IMO.

I'm not looking to be faster than every car on the road or to get the best possible dyno numbers. Just want a MUCH bigger kick in the seat when I stomp on it. The relatively low amount of torque makes this car really lack in the "push you into your seat" department... Hopefully a 550 kit is sufficient for this goal because the ease of installation/removal over a 625 appeals to me and I'd prefer to run low boost anyway to keep reliability as high as possible.

I did step by step on an old E36 with DINAN upgrades...should have just gone all in.

boost is addictive. Might as well go all in

Speaking as someone who did the intake, exhaust, tune route with a NA engine (VR6) and then added a blower after that, there's just no comparison. 30-40 hp isn't all that great in a car that already makes 400 hp, especially for the price. If you're going for power, just go FI right off the bat.

If I didn't get my blower I would have probably sold my car by now. It was the only thing it was lacking in my opinion, and it still behaves like an NA car.

I don't have the 595 kit - I had an ESS 625 and then upgraded to the ESS 650. The power delivery is phenominal. Totally different than a turbocharged car like a GTR or a big torque car like a C63. The power delivery is more appropriately compared to a smaller displacement high revving Ferrari v8 from their 458 Italia. Very similar powerband with torque increasing as revs increase and revs are stratospheric particularly if you get the 8,600 rpm tune ESS offers with their SC kits. I believe it requires good tires known for cold and warm grip like PSS, AD08's, NT05's, R888s or RE11's and solid subframe bushings to be able to effectively get the power to the ground to enjoy it to its full potential.

Can having a supercharger potentially hurt the engine any way in a long run say if it's only driven on street ?

if you have to ask, don't boost the car.

Your basically increasing the stress of all components of the engine and drive train. You will go through spark pugs/ coil packs faster, you put more stress on fuel injectors and pump, vanos sytem. You would most definitely need to upgrade the rod bearings as a precaution if the car has a decent amount of miles on it. The Transmission and differential will have more torque applied to it creating more stress and possibility of failure, not that it definitely will but its a possibility. When I put a JB4 tune on my brother's 335i we had to swap out spark plugs every 15-20k miles as apposed to every 30-35k stock. You might have to change oil more often or at the very least add oil more often if yor M3 consumes oil as it is. On my GTR we pushed it from stock 480hp to 700hp FBO E85 at the crank. While the engine was able to accept that amount of power I was always concerned with destroying the transmission as it was the weakest link in my setup, so I never used launch control. As a bit of insurance I changed swapped all the fluids, brakes, coolant, engine, trans, diff oil. The biggest advice when adding big power is don't be reckless afterwards and not keep up with maintenance. Same rules apply to the M3 and any vehicle that you add any considerable amount to power to over stock, but you can run into similar problems if you track a stock M3 often as you are keeping higher stress levels for longer period of time. Street driving is not a death sentence to a vehicle as it is not always producing max power, though I only street drove my GTR, it was my daily driver and never had any fatal issues. Do some research on what you want to do, and learn how to do some of this work yourself to reduce cost as you are asking your engine to do more than originally designed. When I think about adding power I try not to worry about what could go wrong, as the answer is anything. Just be prepared.
