So far this is what I’ve gone to my “project” 07’ 335i I picked up a few months ago. BMS DCI, BMS chargepipe w/ Tail BOV, ARM Downpipes, MHD stage 2 tune (91 oct), Bilstein B12 suspension kit….and lots of maintenance.

I’m guessing the car is in the 400-425 hp range? What should my next mods be if I’m shooting for that magic 500hp goal? Better exhaust system? 7” FMIC? Other?

I don’t have access to e85 in my area…so that’s really not an option. I’d like to stay with the stock turbos right now also.

What do I need to hit the 500hp mark?

You're not going to get there on stock turbos without E85. But yes, you need a FMIC. Since you don't have any E85 that makes an upgraded LPFP unnecessary.

You would also need a custom tune to push the turboidz over 20psi but still. You're gonna come up short.

Get the FMIC and be done with it imo

Higher octane and a custom tune + methanol. Stock turbos you're limited. If you think you're at 400-425 on a OTS map without e85 guess again.

Nitrous is all you need, there is a stock turbo N54 on spray that ran 10's. Not sure what his dynos numbers were but what matters is being fast, not a dyno number.

With the FMIC.....and going up to the MHD stage 2 + tune, what kind of numbers would it make?

And yes....after the FMIC...I think I'm pretty much done with adding power.

I'm not wanting a drag only car....I'm just looking for a fun daily driver. I've had nitrous cars before.....and they are great for the track, but not for a daily driver. Filling the bottle all the time is a pain.

It was just a guess ...I really have no idea.

I guess all those " Easy 500hp 335i with just bolt-ons" type articles you see online are BS....

If I do the FMIC and step up to the 2+ tune....what kind of numbers would that add?

Those articles are BS for sure, usually they're accompanied by links to purchase those same items.

I forgot about meth as somebody mentioned above, maybe it's more reliable on this platform but I won't touch the stuff.

Edit: As for what HP you're going to get on Stage 2+, are you talking crank or whp? Even with Stage 2+ I think they dyno between 380 and 400ish hp at the wheels. So you're probably less than that right now. Don't get caught up in numbers

You might be making 400 crank hp with your current setup but not 400 wheel hp. Add inlets, the FMIC and stage 2+ MHD tune and you might see 400 whp. Certainly a custom tune will put you there with those mods. You're not going to make 500 of any kind of hp with the constrains you've outlined.

Download "virtual dyno" - it's suprizingly accurate

[iqraceworks]

Thanks for the info guys! I think I will just install a 7" FMIC.....and go with that.

Set of decent turbos and 93 will get you to 500-550 without much issue

Suggestions on a good set of turbos? Do you need to run a custom tune with new turbos, or will the MHD OFS tunes work?

I would argue that they are not bs (entirely) for the 500hp mark. (Based on my personal experience.)

So first we need to remember that we are talking crank hp on a car that is running top notch at stock. Plus the articles I've seen usually have e85 figured in, netting another 4psi(?). So figure that 500hp is maybe ~440whp with my slush box. I am at 360whp (392 ftlb). So 80whp gap. And the dyno was definitely not prime conditions, I was heat soaked with no air blowing over the intercooler. Maybe I could have seen 390whp with cooler air and intercooler. I was having ignition problems as well, so maybe 15whp lost.

My point being that with a 50k mi car (I'm 3x that), an extra 4psi, a BEF, and maybe outlets the 35whp missing isn't unrealistic.

Ugh, I have doubts about this

[Silent9n54]

500 crank is very easy with E85, since you dont have access to it the next best "cheap " mod would be meth since upgraded turbos are a lot more expensive then a meth kit.

Pure Turbos stage 2 or Vargas Turbos. Yes you would need a custom tune.

If you get inlets and a custom tune from a tuner, you might be up there in the 425-475 range without e85, and to be honest that's plenty fast.

FBO w/o inlets and stage 2+ MHD OTS is a good daily IMO. Obviously that wasn't enough for me....

You need a custom tune with inlets. The OTS maps are tuned specifically without inlets. Correct me if I'm wrong but I heard the car runs worse with inlets and the OTS maps.

I did find a few places in town that have 93 octane, and one place that does have e85.

Is it worth it going to the stage 2 93-oct tune? I'm assuming it might run a little more boost and timing vs the 91 tune? It might be better to just keep the 91 tune....a little bit more of a safety factor?

As for as running e85......all of the mhd tunes require a FMIC.....so I probably won't mess with e85 until I do that upgrade.

FMIC only helps with heat soak over multiple pulls to keep your IAT's down. You're at a point where Stage 2+ whatever octane you need a FMIC if you are doing multiple pulls.
