    had the same idea with my setup. Seeing as how my engine doesnt really rev high, I dont understand the point of having those huge laggy turbos that only make power all the way at the top of the rev band.

    Well will see how it goes after new motor and inter cooler are in.

    Dyno numbers and bragging right.
    My s600 put a lot of hurt with 460whp/600wtq on cars with similar whp at times with half the weight.
    That car hits full boost at around 2.5k rpm and then boost falls down near redline

    exactly, never understood the whole dyno queen and huge power scene. Why would you spend so much money to have something basically undriveable on the street or even tracks.

    M6x engines are not fragile. For over a year I had a a nasty engine cut out so bad the whole engine would shut off. I lost some compression in the suspected cylinder but the engine still running strong at 7.5 psi, t66, 10/1 cp, and recently found out I been accidently over revving to 7300 + rpm for I dont know how long.

    BTW. Problem turned out to be a bum coil. So I replaced all of them for security

    Because bigger turbos are easier on stock, pump gas engines....

    Well all those huge power builds I see end up going through 3-4 motors in a span of just a year or two so whats the point?

    That is an often overlooked, or maybe just not understood, benefit of the bigger turbos. All of that fat torque band from a nice responsive small turbo comes at a price of being closer to the detonation threshold. Gotta pick your poison.

    Damn, sorry to hear about the timing issue and resultant motor death. Post up those ringland pics when you gut it. That is not a lot of boost, but the 38 degrees of timing must have done it. Could you hear the detonation, or was your exhaust fully open?

    That's what electronic boost control is for. Let's say I don't want more boost than 5psi at 3krpm, no problem, open the wastegate with 0 duty cycle on the boost solenoid. But from 4k and up I want a lot more power, turn up the boost solenoid duty cycle at which ever rpm you want.
    Easy to ramp up the boost or turn it down, if you have twin 44mm wastegate and a good ecu/boost controller.

    Engine sound really smooth, not a hiccup or any detonation sound at all. Open dump tubes and semi loud exhaust tend to not make it easier.
    Don't think I even want to waste the time to pull the motor apart to find the carnage, just throw it away and keep going with a new one. I would never spend the money to do piston/rod/sleeves on an M60 anyways, so if I blow another one, no big deal. Just a couple hundred $$$.

    For shits and giggles two my friends have s54 powered cars (one is a z3m and the other e36 swapped) both have just bolt-on mods, tune etc.

    & they've blown 5 motors between the two of them compared to me having built just two motors in my 6 years being boosted....heh

    My v8 friends can't even comprehend how stock my motor is, how much power it makes, and how I never blow it up.

    very interesting build, im surprised you fit the 3'' down pipe, i might have tried to re rout the ac lines cause im a little bitch and hate shvetty balls. have you thought about an air too water intercooler. if i were to boost my 540 id go with one cause of the space savings, regardless every cool to see someone boosting m60s, appreciate the documentation

    I could probably fit a 3.5" and maybe only have to put a dent or two in it to clear the pass side head.
    I could care less for A/C, our summers aren't crazy hot here at all and I don't commute in this car. It will only see weekend cruises, track event and lots of night action. For hot days, my S600 and SL65 AMG both have A/C cooled seat, so I don't even sweat a bit while driving those even in 90+ temps.
    There is not much room for air to water, air to air will work just fine.
    My SL65 AMG has air to water, and by the time you set it all up with the plumbing/pumps/exchanger/adding ice all the time etc. I don't think it's really worth it for the street unless your car already had it. For the track and dyno it works great.
