Video: Power vs Weight - Modded E90 335i vs E46 M3

[SeanS54]

A heavily modified, powerful E90 335i vs a heavily modified, light E46 M3. Which one is faster at Laguna Seca Raceway?

subbed to your channel, very interesting video! why not go with the best of both worlds, stripped interior 135i!

I wonder if the MHD cooling table modifications would have helped your heat situation out.

I am on all stock coolers and hit 270f oil at the highest on the 'sport' setting, with no noticeable power reduction, in 90f ambient and at similarly modded M3 pace.

The new MHD coolant table changes really do help. Been meaning to get the BMS thermostat lever to see how that affects things. Don't want to stress the WP too much TBH.

My pump is pretty new but that sits in the back of my mind- it's why I didn't do the track setting. Maybe I will flash it back to stock for the street.

Sean- Does it feel at all lazy having 275s on 9.5j? Seems a little pinched

Thanks!!!

Love it! Stripped interior 135i would be great on track, as long as you don't encounter limp mode.

I think the tune - more boost = added stress is a large part of the problem. Never tried it with stock boost, that would be no fun on track.

I've run the JB4 G5 ISO and the MHD Flash and still had issues. I'm not sure if the MHD cooling tables were available then.

I did have a custom Setrab oil cooler and custom thermostat which opened at a lower temp but still overheated.

Not sure that was avail then but good to know.

275's on a 9.5 feel great. Per Nitto's site and other tire manufacturers, 275's are acceptable and quite common on a 9.5. Some guys run 10 or 10.5 but then you start running into clearance issues with the strut or fenders and it's a bit heavier.
