Modded M3 vs Modded 335i Data

M&M · 10-13-2009, 02:33 PM

1st the dyno's, up here at my elevation. 5500ft at sea-level so the M3 loses 17% power. M3 on dyno, Chip + Xhaust, pump fuel, 331hp. Makes 385rwhp at sea-level.

My old 335i on the same dyno up at 5500ft. Chip, intake, full Xhaust with catless downpipes, Spearco cooler, Aquamist meth injection, Forge DV's, pump fuel, 375hp:

I have many logs at sea-level & at altitude. I think the most meaningful would be to compare times from the same test "track". Lucky I have a few logs at the infamous Toll which is at sea-level. The test track is totally flat. Drops like 5-6m in the course of 900m. So the gradient is flatter than most drag strips around the world. After 900m it drops a bit, but that's the same for both cars. Comparing times from different "tracks" is meaningless as the gradient & even the elevation will be slightly different & skew the results

So here are the best runs of my 335 & M3 at the Toll "track". Both times with pump fuel & in pretty warm ambients, between 27-32deg C. So the cars weren't properly prepped both times. No racefuel, no cooling of the manifold, street tyres with normal pressures. So basically as they run on the street. I'm sure in race trim one could drop significantly in Et & both cars (Expecially the 335) would gain quite a bit with racefuel. The 335 is the blue line in all the pics.

And here's the 60-130 comparison at sea-level:

And here is the M3's best 1/4 mile, street trim, street tyres, unprepped street:

And the 335 at the same "track":

hey I have one question..it might sound like I'm poorly informed, but howcome the e92 M3 always gives around 350-380 on dynos when its supposed to have 420?

Yeah that and altitude losses.

Good stuff, Thanks for all the data and info.

Great post. I appreciate the attention to detail. What flash and exhaust do/did the M3 and the 335 each have?

MrHarris · 10-13-2009, 11:17 PM

Very nice. Give details on mods

DLSJ5 · 10-13-2009, 11:32 PM

Love your posts Bro, do you plan on going FI in the future?

isugoo · 10-14-2009, 12:06 AM

how much dollar amount did you spend to mod your 335i?

bigjae1976 · 10-14-2009, 02:45 AM

An M3 will always have an advantage over the 335 since the M3 is geared so much shorter.

Eugene-TAIWAN · 10-14-2009, 03:08 AM

335i 's are fast!!! small mods. Big results!! but driven one don't really like the chassis set up.

Nice post!

e36jakeo · 10-15-2009, 10:50 PM

Had a 335i with a tune. Seat of the pants seemed faster than the M3 due to the mountain of torque right at tip-in. M3 just keeps pulling, and finally pulls ahead.

mixja · 10-16-2009, 02:02 AM

Nice comparison - does the M3 have a full exhaust or just catback?

A-Man · 10-16-2009, 05:05 AM

KWY91 · 10-16-2009, 06:13 AM
