Cams? Chips?

[89BMW535i]

What kind of cam and chip is the the best with out killing to much of my MPG?

[zubbie]

forget a cam upgrade. $$$$ for modest increases in power. EAT (Mark desylva) is generally recommended for a chip upgrade.

I love Clams and chips

Agreed 100%. Cams are spendy for not a lot of powah. Chip tuning on M30 motors goes a LONG way. That, and a nice muffler will produce more than any cam out there. (not to mention that you will loose a ton of weight if you ditch the muffler.....E34 mufflers weigh 6000lbs.)

I have cam and chip (and other stuff) with no tuning and I'm at 200/212 to the wheels. Best bang for the buck would be Miller MAF instead.

Hey just curious as to what gains are seen from cams?

[E34ührer]

A schrick cam MIGHT get you 15-20......but that is a very, VERY generous estimate.

A cam alone won't get you much ($1000). Add a better flowing head, valves, exhaust, intake etc and you now have a the equivalent of a Hartge H2 SP or an Alpina B10 3.5 if you are lucky which max out @ 250 hp at the crank. Some serious money is involved for that.

Take Hari's advice. If you want power out of an M30 you can get @ 10-15 hp out of a Miller MAF and chip ($500) or spend $2 - $8K on FI turbo system (depending on how resourceful you are ) and get 250 - 3xx hp.

It's no small block chevy with loads of potential for modding. At 3.5 lires (213 cu inches) the M30 is already at 1 hp / cubic inch stock. You are already way up the $/hp increase curve before you start.

turbo on a 3.5 should yield way more than 300's range shouldnt it? Unless a daily driver and therefore low psi is desired.

True, but I kinda like to keep things conservative. Anything over 350 hp to me would likely mean strengthened internals in the bottom end which will put the financial issues out of reach. I am starting to talk out of my ass now though. We need Jon K to spout more on this one based on his experience with the M50 and the mega bucks he has expended.

Go to the Miller site http://www.millerperformancecars.com/articles/informatory/42-miller-ms-engine-system.html and look at what a stage 2 M30 kit will run ($12 to $25K) for a whopping 331Hp 397 TQ http://www.millerperformancecars.com/images/Documents/MS%202%20Price%20list.pdf

TCD kits http://www.turbochargingdynamics.com/category-6-Turbo_Kits.php are less expensive but still in the same ball park as millers for performance.

that looks tasty

Just have 5mall5nail5 build you a clone of his setup. It'll only cost you what a good replacement kidney would to have installed.

Ha ha, deal (kidneys are free up here ;))

[E34ührer]

I have a spare kidney anyhoo........it's going on eBay if no one here is interested.

Fixed.

Won't need a TMS chip with the Miller MAF, it comes with its own, ans soon, one will be able to get one of the new chips with a USB port on it to do some future tuning with.

ah didnt know that

[Antrieb325]

If you already have the Turner chip, can you use the miller maf with it and not use the miller chip???

you can prolly get away with it but it'll run like shit
the one from miller is included with the MAF(i think) so just use that

[zubbie]

sorry, you can't use any other chip other than the miller one. Remember you are now feeding the DME MAF signals rather than AFM signals which are two completely different beasts. I'd be surprised if it ran at all.

[89BMW535i]

.....so I guess I'm gonna go with the Triflo and the MAF.Thats like about 1200$ and then maybe some new valves.It's gonna be awile.

You don't have to get a Triflo, you can alternatively, have a good muffler shop fab you something with a Magnaflow or similar.

I had a Magnaflow on my '95 540i/6 sounded great and was relatively cheap. The only real expense was fabricating the pipes from the cats to the Magnaflow muffler, as I had the resonators removed as well.

Exactly.

When one installs the Miller MAF, you also need to swap some pins around in the ECU connector (they send you a pin-out tool) as well as add the IAT wires to the MAF plug at the intake side.

So it would be highly doubtful if it would run at all with another chip. That chip would be expecting German from the AFM instead of Canadian from the MAF.

It would be like "WTF?? &$*&$%$ Idle. &$&*$ Power."

Hahah...aren't people getting higher gains from the Turner chip than just the miller maf and chip? Turner's website said something like 43 hp and 21 ft. lb torque in gains? What is your redline with the miller chip? Are there any other maf conversions available?

Naw, m30s can take about 500 whp before things start to break. I would never get up there stock but I think 450 whp is a safe bet. I guess we'll see what happens :evil2:redspot

That is a big NO. Those quoted gains are not at max HP and TQ. They are somewhere in the curve. If you need further explanation I can break it down further, but it's just a little late to be typing something that was cleared up years ago. :)

[Antrieb325]

Link to thread?? Well since it's not so late, you can tell me now! haha just messing.

I'll explain it. The claims of 43 more hp may be true but it's not 43 more maximum hp. Say they say maximum hp is at 6000rpm or something and that it is 220hp (so that's like a 12hp gain). Well lets say with the stock chip that at 4000rpm you're making 140hp but maybe the Turner chip produces 183 hp at 4000rpm. So, the curve has been adjusted and it does make 43 more hp at a certain rpm but it's not a 43 maximum hp gain. These are all hypothetical numbers but if they're saying a huge gain like that, it is definitely at the actual peak hp.
