Donít know if its significant but in most of these threads it looks like the most enthusiastic ďbuy M3Ē guys are driving older 328/335ís. I also think that a lot of the fully optioned 335is buyer could have bought an M3 instead but like me donít believe itís a useful street car.

Also like me I bet a lot of new 335is buyers will be moving to the F series M3 turbo when it comes out with bottom end torque.



Its also interesting how the little Burger Motorsports decal attracts M3 like a moth to a flame. Other then the decal itís a pretty good sleeper.

Many factors involved in that comparison.... Driver,Temp, track conditions, play a major roll in that....I would say 9 out 10 races the better e
Suspension,tranny,cooling, and power of the Is will prevail over a stock N54 or N55

Better suspension? where's the stock LSD?, better tranny? It doesn't seem to be able to hold more power than the 6AT without a rebuild. The DCT also has cooling issues, as I'm almost 100% sure it lacks a DCT cooler, like the M3 and goes into limp mode when pushed. more power? take a look at the dynos, it's just a tad bit more low end torque. Without the abusive launch control, you're in the mid 13's.

Enough talk though. I just got back from gingerman raceway yesterday, where I had no trouble keeping up with a modded E90 M3, who is a friend of mine. I'll be there again in may, and will be in Mid america motorplex in July. If you, or any other 335is in the chicago area, want to show me this big difference in person at the race, please PM me.

Thanks.

Changes since then New 335IS specific custom Map 6 no charge, FMIC $750 delivered current power has increased but how much is unknown.
So, would JB4 be OK for a lease car, and be able to return it to stock later?
For a stock 335is, would Map 2 be fine on pump gas? Map 5 if I mix in 100 octane?
Lastly, do you do any track days or just drag racing? I am signed up for Kershaw in May. But will likely do stock as a base-line, although Kershaw can make use of more power.

Some answers.

I don't use launch control & car will run in the 12's with a 2nd gear start as recommended by Terry at Burger Motor Sports. Map 2 & 6 is good on 93 pump, Map1 & 5 for 91. My pure stock baseline dyno was 314whp. 335i generally run 277/280whp & as low as 265whp on 91 octane. The stock IS as opposed to "a little more torque" has about 80ftlbs more then the 335i.

One of the other 335IS guys with a German developed tune he is testing for them & who has an FMIC & does use launch control is running 12.0 with 1.8 60 foot times also with no transmission problems. Expect if he adds down pipes it will drop nicely into the 11's with no heat or trans problems.

Drag race on occasion at Rockingham, NC but have not done any track days in it yet. I will go to VIR when the NC BMW club goes up there. Not serious about either just looking for a little extra on the street.

Way back when had a number of sponsored rides & hold both NHRA & SCCA licenses

On I6 & V8 M3's I can/have just driven away from them both from a standing start & a roll. Compared to the V8 I have about 10 more BHP & 105ftlbs more torque which comes in about 2100RPM sooner. The V8 M3 should be better at a track day due to suspension. Not bad for $500.

I have not run the new JB4 IS specific Maps against the clocks yet. Someone else with the same car less the FMIC I just added (my only mod outside of the JB4) + a DCI has posted IIRC 12.5 @ 114mph from 12.8 @ 110 with the new Map6. Not sure what tires he was running but I have Conti DW 265/30/19’s on the back & 235’s on the front.

BTW this is a pure stock 335IS first drag strip run, best et 13.1 with run flats. Watching this guy trying to stage you can tell he is not a track rat.



The JB4 can be unplugged when you want to turn in the car also a good plane for warranty claims. Will take about 15/20 minutes mostly to remove/install the underhood plastic panels.

Some EDITS

A JB4 135I N55 7DCT made some 12.0 - 12.2 runs today
