What Bolt On Mods Make Power!?!? E90 M3

[kerkiraios00]

Hi everybody, I have an E90 M3 and I'm looking to get a lil more power out of it excluding s/c and turbos bc that's obvious, my question is would cat less headers, cams,intake and a remapped ecu do the trick? Looking to get like 30-40HP(more would be nice also ) lol more out of it. I did a search and couldn't find anything specific sorry if I made a thread for no reason.. Thanks in advance

And pulley and you are good to go

And I'm looking at about 40hp? Is that wheel or crank?

I put down close to 400 whp with tune,pulley,intake,axle back and sec cat delete xpipe !

[benzy89]

Tune, Full Exhaust (Test Pipes or X-Pipe + Rear Section), Intake, Pulleys

Cams (and/or aftermarket Headers) are expensive, require a lot of labor & don't give you gains that justify their cost

They are correct. A catless x-pipe will get you the best gains for the buck. Tuning it will get you additional gains and rid of that SES light.

Now I could also get an additional 40-50 hp by moving to the east coast down to sea level and running 93 OCT.

How is that meth kit along with the procede. Any issues? Would the longevity of the motor be compromised running meth? I'm trading my FBO+Meth 135 and since i'll have shiv's PWM kit laying around i figured why not try it on the M along with the tune. I was very happy with it on the N54, thing was a monster.

I suggest going with our drop in filter, cat-less xpipe and tune to start.

X-pipe alone is good for 20 whp.

Here is a dyno with filter,pulley,tune and rear section only. (stock X-pipe)

Save your money
And get the vf 540 kit

The only downsides of running meth is that you have to keep buying it. Since you've already had this installed on your 135i, you know how the Procede and Meth are integrated in the CANBUS, making it very convenient, safe, and applicable only when necessary. You won't see the big gains out of the M3 that you saw in your turbo'd 135i, but it is a significant improvement. The guys running stock M3s around here can't keep up with my or JA///MES' M3 with catless exhausts, Procede, and meth.

The only issues I had were during the beta testing when we were figuring out the differences in the N54 and S65 fault codes. The SES kept coming on even though we had what we thought were the right fault codes built in the Canclear function. Shiv made corrections and they are built in and working as advertised in the latest firmware (which firmware and map updates are always free by the way). Shiv also sent out upgraded, larger nozzles to us, also free. The older ones had a different spray pattern that was getting the filter soaked. The new nozzles work a lot better.

I think the Procede uses a different harness for the M3's ECU.

skip the cams, not worth it

[m3buckeye]

What about this combo:

Dinan 3.62 LSD
Dinan pulley
Dinan intake
MRF Velaforza exhaust
MRF tune


My calcs show this setup to be 489hp (crank) and 396 ft/lbs of torque for those mods.

Anyone have any thoughts on these additions?

High flow cats and a pulley. Axle back does not ad any power.

Don't forget probably the easiest way-if you don't do meth, than add race gas or e85 to get to 95 octane atleast. That is good for up to 20 hp alone. So if you do high flow cats, pulley and race gas even without a tune you are at 30-40hp more.

That was back in 08, I'll try to dig out that dyno for you. And BTW you ain't raining on my parade in any way

The underdrive pulley, catless or high flow cat or primary cat delete x-pipe and tune are all generally agreed to be power adders. Whether one brand adds more or less than the others seems entirely up for debate. Just use a shop or shops that you like to buy the parts the shop sells and recommends.

Obviously, of these, a catless x-pipe has less restriction than a high flow cat x-pipe or a primary cat delete x-pipe and most of the reported dynos show the catless pipes making more power. There do not seem to be many dynos showing gains from changing the rear exhaust.

The intake is a subject of debate. There are claims for power gains, but the claims have been disputed. Certainly on an older car with charcoal filter, there will be gains, but much or all of those gains might be there just from changing to a high flow filter alone.

I don't see 489 crank hp or 396 lbs torque being made from those mods. The 3.62 diff adds no engine torque. It just multiples what the engine makes. Its effect will not be reflected on an engine or chassis dyno (except perhaps as minimally greater drag on a chassis dyno).

489 crank hp would be over 400 rwhp. Search around and you will find the cars that cracked 400 rwhp SAE to be exceptionally rare. However, there are plenty of cars with the mods in your list making around 390 rwhp SAE and I don't think that works out to 489 crank hp using any realistic drivetrain loss multiplier.

Thanks for all the input everyone I've gotten a lot of good info but still have to do some more research. All I have as of right now is a miesterschaft exhaust, I def wanna do the x pipe just not sure how crazy loud it will get. I dont understand why you would need meth without running any kind of forced induction system? (sorry ive had subarus all my life) lol That VF 620 s/c def looks sick thought, I wonder if there would be any issues with it after you install it like any future problems motor,tranny or diff?

[pbonsalb]

These engines run very high compression and seem to be octane sensitive. The meth gives you the equivalent of higher octane than any normal pump gas. This allows higher ignition timing than you can run on pump gas, and more timing makes more power. I bought the Vishnu procede piggyback with meth injection for this reason. I think it will outperform any tune running 91 or 93 octane pump gas.

You should just do as I did last week, skip the bolt-ons and just get a entry level s/c kit, the car wont sound unreasonably loud, will have a lot more power then any FBOs M3 and wont cost that much more then a X-pipe+exhaust+tune+pulley+CAI+meth and at least you're sure to be satisfied with the performance. Ususally I would be more concervative with the mods on a expensive engine like this but it seems like ESS has sold a couple of hundreds of their kits without a single engine failure so that's enough to put me in confidence!

I bought it, have it, but have not installed it. After looking at the standard "quickie" install, I decided I would rather trunk mount the tank and pump so I had to order more parts. I installed an Aquamist HFS4 tank and pump in the trunk of my turbo E36M3, so I am familiar with how to do it.

To see the "quickie" install, go to the Vishnu website and review the pictorial.

I will post my thoughts after it is in and I have driven it a bit. Hopefully that will be within a couple of weeks. I'd like to install it this weekend.

Im running it without ANY issues at all. The car runs strong all day anyday. Install took about 2 hours. If you decide to go trunk mount may be a little longer. Just know, the M3 has a different wire harness for the REV3. With just removed secondary cats, magnaflow exhaust and Proceed with Meth i made 400 whp on the same dyno that other cars needed full bolt ons and a tune to make 400whp.
