Hey guys just got me a 735i the other day with the 3.5 v6. Was just wondering if any mods are available for a little more power. Its got a ram air box and an aftermarket exhaust already, just wondering if there some type of cheap tricks to gain a couple of ponies. Just curious
thanks
A chip would be a good place for a little more power. Hope you enjoy your new car, btw these are inline 6's.
yeah its pretty badass
i figured outside of a chip there isnt really much else
why is the inline 6 relevant? im confused lol
because there is no V6 ;-)
Chip: What is the Bosch Motronic number of your car? It is on a sticker outside on the Motronic hosuing in the e-box in engine room passenger side. (under the black cover)got me a 735i the other day with the 3.5 v6
The last 3 digits are important, 150 or 178 or 179.

oh i guess v6 is a regional thing then
we call anything a v6,12,8
and shogun i'll have to get back to you on that car is currently being worked on by a friend of mine
do you say V4 too?
do you know what the V refers too when u say v6?
its not a regional thing, it just shows that you don't know much about cars... but stick around here and you should learn pretty quick

I have a Mark D'sylva (E.A.T.) chip specifically tailored for the m30b35 e32 735i; for sale if you are interested.
I'm not ready to make any moves yet
just trying to see whats available because i wasnt able to find much
what type of gains could i expect from this chip? just curious
and as far as not knowing about cars
yeah im more of a moped guy
A chip like turner motorsport would give you
Horsepower Gain, 1988-92
+ 43 @ 6250 RPM
Torque Gain, 1988-92
+ 21 @ 2000 RPM
New Rev Limit, 1988-92
6800 RPM
I heard shogun's chip is very good also.
I would think are are many more important things to worry about than adding more power out the gate. How many miles are on the car? What kind of service records do you have? When was a tune-up done (plugs, wires, distributor etc...), when was the transmission last serviced (fluid, pan, filter), fuel filter etc... Have you checked to see if all the vacuum lines are connected? How do the CV joints look (all gummed up, rubber torn? Before you start adding torque to the engine and everything behind it I would make sure any deferred maintenance is taken care of and drive it a couple thousand miles. This engine is really sufficient and there is always more. Bugatti just added more power to the Veyron. Did it really need it?

lol yes 1200hp >1000hp
Glare shielding www.justoffroad.org
I do not believe in that number:
That would be >20% based on even the higher HP EURO standard versionHorsepower Gain, 1988-92
+ 43 @ 6250 RPM
http://en.wikipedia.org/wiki/BMW_7_Series_(E32)
standard EURO 735:
211 PS/HP (155 kW; 208 hp) @ 5700
but the max power already comes at lower RPM
305 N·m (225 lb·ft) @ 4000
here the curves

A chip does not make wonders, I always tell people
up to 10% more HP
up to 10 % more NM.
And avenolpey is right, there are more important things to do for him now: maintenance, inspection. buying replacement parts and also>>>>>
saving some bucks for future repairs which will come for sure.

Shogun & avenolpey are both right. Those Turner motorsport advertised HP/Torque gain numbers are definitely not going to be achieved in the real world with a chip alone.
I've tried 1/2 doz different performance chips and they all have their pros & cons so I've learned not to chase advertised numbers anymore.
BUT, a reputable/quality chip will produce noticeable gains in idle quality, part & full throttle power + response. The best part of a performance chip is the improvement in the way the car drives by being behind the drivers seat, which is not always measurable on paper.
well said, that is the most important, how it drives. The people in Germany which buy most of my chips just confirm this, more NM in lower RPM ranges, part+full throttle power + reponse, the higher max speed is just a by-product, no one actually needs it today anymore in such dense traffic and most of the countries have a speed limit anyway. More and more people buy now from me the chip for another reason, to save fuel. Some reported a fuel saving of 1-2 liters per 100 km in Germany and over the whole year that is quite some bucks. And also this fuel saving debate is basically in theory, because no one drives the same route every day at same speed and throttle at the same outside temperature and humidity.

I don't think the chip will give that much power, I just copy and pastes from Turner's website.
who makes the best chips for each engine?
im sure one chip maker doesn't make the best chips for the 730, and the 735,and the 740, and the 750

probably no one knows, that is word of mouth. If someone is happy, he tells it and others buy, but there are only a few people which have tested various chips.
It already starts with the M30 engine, there you have the M1.1 and M1.3 Motronic.
What does the customer want from a chip? And so on...
My ones are not the real hot stuff for racing or whatever you call it, it is better performance in daily driving, just taking out some of the reserves from the original factory setting. Factory setting is considering worldwide conditions such as high(est) altitude (M30 and M70 do not have knock sensors), fuel conditions in various parts of the world and so on. Just see what we have in the world ROM, MON, AKI and whatever that is called [ame]http://en.wikipedia.org/wiki/Octane_rating[/ame]
The best chip maker asks you to come to your shop, they test the car/engine on a test stand for power, you tell them what you want, they set up the requested performance for the engine as much as is possible, make another test on the stand and then you pay about $1000 at least.
I have another M1.3 M30 chip under test run with various people in Europe for more than 12 months now, that is a hotter version than what they buy usually, you need high octane, feedback so far: good idle, a very good response, also from lower RPMs on the throttle and no RPM limiter, higher top speed, disadvantage for the daily driver: quite high fuel consumption. But if they like the extreme, they pay for it with higher fuel cost.
A real power boost is only possible with turbo charging etc.
But we also have to consider the age of these engines, many of them habe in excess of 150 k miles, and no one asks his 80 year old grandmother to run the 100 meter dash in 10 seconds. There are limits.

Shogun,can you give me a lowdown on your chip,I have read it before ,but can you refresh me?735i 88
This is a V6:
This is an inline 6:
There's nothing regonal about that. BMW has never made, and hopefully never will make, a V6.
Best mod for a 735 is to sell it and buy a 740. Instant 80hp gain for no cost. The 735 engine is very good though, and can make huge power if you want to turbocharge it.

i had the turners chip in my 735i before the turbo setup and it helped out incredibly. I also had a billy boat catback with no cat and an intake already. Mass air conversions and put it on a diet and get rid of some of that weight in the beast. This is the nest bang for your buck. You can do an adjustable fuel pressure regulator, intake, exhaust, bigger plug wires, msd coil, headers, and alot of suspension work. You can turbo it like i did with a 745i setup and with a few tweaks it will be the m7 they never made. You just need to figure out what you want to do with the car. The sky's the limit and if the don't sell it make it

all depends on what you want to do with the car and how long you want to keep it and how much you want to invest.
If it would be my daily driver and the only car, I would leave it stock and invest in maintenance, in case it is a fun car, the wallet is the limit

wow took a while for someone to actually give me some new ideas
thanks fast!
like the flat black btw
Great looking ride! I have recently gotten an 88 735i and am looking for some nice wheels for her. What do you have on your car? VERY NICE!
Miller has a real nice MAF kit that comes with a chip for about $400 shipped last I checked, really a great deal all things considered. http://millerperformancecars.com/cat...&category_id=6
How many miles on your motor? 120-140k, I would roll in a new timing chain and replace the guides. Camshaft being out of time is losing 10-15hp too. The rest of the top end... head/cam/intake/etc is all matched well to the stock exhaust. The OE cat leaves some flow to be desired but the manifolds flow well as does the resonator/rear muffler.
The 735i also is already geared low so a high stall torque converter will help it get out of the hole. Aside from that you are about maxed out... it is around a 4000lb car with about 200hp stock.
I make E23 parts.

Ford, MB, and GM round out the pack.
