Hi guys,

I am interestet in your opinion:

Walked U and me asked already why you expect to increase the 335i engine performance output using a tune like PROcede V2 without supporting this tune by additional, supporting hardware. Also German tuners are selling V2 output tunes together with FMIC's and catted Downpipes ( e.g. Noelle ).

We can talk about priorities, IMO a better FMIC's priority is high.

A more efficient FMIC would directly impact the engine's working environment for a tune like PROcede V2 and behaves like an octane-booster ( beside some other useful improvements ) . Less IAT's = less octane needed.

I am interested in your discussions and feedbacks.

Cheers
Eugen

I am with you. FMIC is on my mind even for V1.47. Or at least something that can take care of the IC heat soak issue. I might try to band aid the problem with a water sprayer or co2 sprayer for the I.C. next spring. But with the added boost More cooling area is definetly needed. Space seems limited for something really aggressive.

The first 20 minutes of a drive the car pulls so much harder before IC heat soak takes place. Its annoying but I guess the nature of the game with Turbo
cars.

did you ever get your spearco FMIC?

[stressdoc]

Folks in the mod business can market performance "packages" for more profit than simple ECU flashes/piggybacks. That said, FMIC seems like a good idea, but forged pistons, etc. might be wise as well.

I did, it's damaged due to the transport, I guess. A high quality device. Will get a replacement soon.

Water/Meth is a better option. The stock cooler is pretty efficient. Complement that with water & your IATS's are in check & dett is a non-issue.

I dont think I have really experience heat soak in my 335i yet but I guess if your on a autobahn doing top speed most of the time that engine is going to need every bit of cooling it can get.

Just curious wouldnt downpipes also help to ride the turbos of excess heat? Also the car feels heat soak by its sensors couldnt that be corrected by a Piggyback. I remember reading about the GTO guys having to move their heat sensors so that their cars wouldnt get heat soaked so fast.

[e.n335]

I think, FMIC and DP's are the key. When time will come, I let you know what I experience. IMO, heat is all about the N54, maybe in other ( all ) turbo applications as well.

+1 so did you ever do that top speed thing? what about going faster then just 155?

[DrDomer]

Heat is the number one enemy of forced induction... At least I've read that many times. Ugh... If only I could put on an FMIC in a leased E92.

PROcede V2 is wired & set up for high speed. I have to wait for the chance . I want to see the this V2 335i running 300 km/h ...

I think you can use a true bolt on kit, not requiring to make any cut's or the parts you have to cut have to be cheap, easy to exchange and require no painting ...

Heat soak of the engine and heat soak of the Intercooler are two differennt beasts. Related but also seperate.

I agree with M&M, water/alcohol/methanol injection is cheaper and more efective, it yields the most power and torque.

Don't get me wrong, a proper well designed IC could generate some power but the stock turbos might not benefit with a huge IC.

I rather do a full exhaust before I do a intercooler. If you already have the exhaust then yes, the intercooler could be the next option but keep in mind that the front cooling area on the bumper is a limited factor.

I gained 21whp/64lb/tq increase on a Mustang dyno to all 4 wheels on my Eclipse by just engaging the methanol and doing a retune. I was able to increase the boost from 17psi to 24psi. My gains would be similar to 40hp and 100lb/tq to the engine with the methanol.

The stock intercooler should be good for now.

Can someone please explain what this meth injection is? and how much does it cost?

Damn, Your so lucky you live in europe I wish I was out there simply for that reason. I have a euro deliver on a 135i with everything on it so hopefully my procede can just swap in without any mods and I can see how that feels. I have to wait till April or so to get it though.

[3thirty5]

I'm having my Spearco IC installed as we speak, I'll post my feedbacks after I pick up the car this afternoon.

[3thirty5]

oh, and I'm currently running Procede V1.47 (V2 on the way), so we'll see what kinda of gains I get.

[sambonator]

Is there a water/meth injection kit available for the 335i?

[BaLLzZz]

A FMIC is crucial for this engine when modding. I have told many people this and no one seems to listen. Without the FMIC you are wasting money on all these other mods combined. The V2,DPS,Exhaust... will be consistant for only 2-3 runs consistantly losing power. With the FMIC you will retain whatever power you car is dynoed at threwout the powerband. FMIC FTW LOL

[2ABRUPT]

Some of you guys are jumping the gun and not really knowing what you're getting into.

Please listen to us folk who've had turbocharged cars for years.

EVO8MR is correct, you really shouldn't focus on an intercooler as your first mod to the 335i.

The main problem with the cooling and high temps of the 335i has to do with the turbos themselves. They are very small and BMW probably decided on those turbos to keep the drivability of instant torque a high priority. But the downside to that is that modding the car will lead to some problems on the stock turbo.

If I had a 335i, here's what I'd concentrate on. Ask yourself these questions knowing that the stock turbos will produce a LOT of heat and will in turn make the oil system hot as well (not to mention the intake temps).

1) How much more safe power do I want out of the car?

2) Do I want to focus on reliablity?

3) Do I just want more power regardless of reliablity?

4) How much am I willing to spend?

The upgraded exhaust is a good first mod because the tiny size of the turbine wheels is surely producing a lot of backpressure on the engine which would create heat and lose volumetric efficiency of the motor. It will also be SAFE and allow for better gas mileage as well as some power.

I wouldn't jump on the intercooler just yet because most intercoolers are designed well for the turbo that's on the car stock. When you start pushing the stock turbos to the limits, then you are talking about making the stock intercooler less efficient which would require an upgrade at that point.

This is true, in theory. But if you don't increase boost pressure, then it would take a lot longer to heat soak your intercooler. I'm assuming that everyone's not buying a 335i just to take it on a road course. I'd get the exhaust first. The intercooler isn't going to buy you THAT much temperature drop. Runs may be more consistent but there is no guarantee that it won't cause the ECU to go into limp mode anyway.
