£150 quid for a nicer drive and better throttle
response doesn't sound too bad a deal? I was originally quoted £300 for a chip and rolling road tune which seems steep although I need to look into it further. |

These older cars dont see much true feel of extra power but the smoother delivery of power is a nice touch. I charge lower for this work even though the job is harder because i feel the gains simply dont justify a price tag of £300+ Maybe if you had a 530d then the gains in my opnion are worth as much as you care to pay and are vastly different to original but on these cars the gains are less prominent so the price reflects this. I did dave`s who went on the dyno day and from what i gathered, his gave very good results? |

Andy As you rightly says a bhp here or there who cares the cars are not going to produce the factory standard Ross's had done over 160k,Ivan's had 165k there was a black one with over 220k on the clock. Mine had 167k on the clock.
I dont know if anyone played with Fuel, Mine was achieved with Sainsburys finest unleaded 95 RON Three things really impressed on the day an early Red 635 with a Fritz manifold ...it sounded terrific. James Sohls induction kit- it looks good but I also think it delivers and as a wise man said " Power corrupts, absolute power corrupts absolutely!" The nitrious Kit on Tony Crane's car , what fun he must have with that Regards Rob |

A rise from 220bhp (or 218bhp for the "lesser" cars ) to 230bhp is nice to bring up at the bar over a pint but that's peak power at high revs. In other words, only 0.009% of the time. The drivabilty aspect is more important more of the time.
A chip is on the cards for me when circumstances permit. I think a new AFM will be needed first & there's an insp 2 heading my way. |

That was a misprint. It should have read 156k. |

Playing with engines in the 150k miles plus bracket is really a waste of time in my opinon. You have already lost wads of power due to poor compression with worn rings and bores. Drive ability may have improved with a chip which is always great news but the power will never be there. Depends what you are looking for really. I'm still modifying my M635 which is pushing probably way over 300bhp now but it has cost loads of money. Been down the cam route which completely changes the engine characteristics. Really really addictive above 4500rpm to redline at 7000 but the loss in low down torque is an irratation on the road. Mines heading towards a track car now but that's my choice. Save your money and invest in some desent oil to prevent bombing of the engine or....... get the chip get the cam get the cold air induction then rip that engine apart, new light weight pistons, rebore, port and polish etc etc. It's great fun, but add in the brake upgrade, uprated and fully adjustable suspension, proper wheels and tyres and things start to become a bit of a finanical joke. Just don't tell the misses. PS Horsetan - fitted that M6 suspension yet!!!!!! Afterthought. M635 - 1986 Je Pistons with Total Seal rings, 2*272 schrick cams,ported and polished head,bespoke k&n cone filter,fully adjustable front and rear suspension,dinan stage 3 suspension set up, e34 al control arms, goodrige hoses, red stuff all round, 8*18 BMW alloys, e28 M5 25mm front ARB, dinan rear 19mm arb, 750 bush mod, UUC short shift, 25mm 750 brake master cylinder, Sparco front strut, BMW rear strut, K-mac front strut mounts (on route) - Scottieturbos MAF conversion (next year) See- told you it becomes a joke! But fun. Have fun.

Cheers for that Ian you've made me and my car feel insignificant.
Seriously though I understand what your saying I've already spent plenty of money on the car since I bought it a year a go. It's all about making small mods and improvements to my car as and when time and finance allow. I'm not going performance mental because there's no point if I wanted to do that I'd start with an M635. I didn't know anything about cars or engines a year ago but I'm starting to get my head round things now. My 6 had 85,000 on the clock which I've no idea if it's legit as the service history is only stamped up to 60,000. I think the engines had a new head on it but I (or somebody that knows what there doing) need to take it a part to find out what state it's in. Your list of mods is impressive and would be even more impressive if I could understand what half of them are. I really need to get myself to an event and speak to some of you fella's face to face. Although that could be the beginning of the end to financial ruin! Cheers |

All in good time, Ian, all in good time . I've got the MoT in a couple of weeks, so let's see whether my local station spots the almost bald 225/60/15s
His work on the car makes everyone feel insignificant
Ah, you're in very very good company
Nobody knows what they're doing where a Six is concerned! That's the fun of it.....I think.....errm..... |

Ah ha. 85k miles with history (ish) and new head. Good starting point. Learning fast I see as well. Any consolation - mines all self taught over 20 years of tinkering about. You are in safe hands here on this board. There is loads of experience and loads of mods to do. Just take your time as your budget allows, do the sensible things first then build on that. Gaydon would be a good meet up Ian

ah yes, that'd be my car. In fact this is a misquote though (even though this went into Total BMW too)- my car has a full Fritz's system, manifold, down pipes, both boxes, one-off clamps etc all in stainless, lovely... Best of all its not too noisy with the windows shut; I drive my aged mother around in it sometimes and she doesn't feel embarrassed until we have the windows open and I clog it in a built-up area; then she does... oh yes... cheers

Brucey, is yours manual? It seemed that the manual cars faired better on the rollers power wise..? Also, from the article it seems so much better to fit a decent manifold/system and a proper cold air feed if you're re chipping - together they seem to do quite a lot for the overall power. It is interesting to see just what these cars make at this age. I noticed James' car making 222hp with (am I right?) a chip and manifold and custom cold air feed. So have these mods only released 4hp (from 218) or could the figures have been higher with a newer motor.. ? Edited by dog man |

Went to see a chap on Saturday who seemed uber
knowledgable about chip tuning he also came recommended by a few people. He was telling me about all kinds of horror stories concerning so called experts who perform the tuning without a rolling road which he claims is an absolute no no. He's calling me today with a price which I have a feeling is going to be around £250-£300. He's not promising more than 14hp and has confirmed the smoother throttle response etc... Getting my exhaust system tweaked on Tuesday - Cutom stainless rear and new manifold gasket which is blowing. The rest of the exhaust system is in good shape so I'm going leave it for now. I may get the fritz manifold next year. The same company have also come up with a neat solution for my new air filter which is currently being held on with cable ties. I'll post pictures as soon as all the work is done as there are cheaper solutions to the set up that James Sohl had made. |

-back to back dyno testing and temperature correction are required for accurate comparisons. I'm not sure the latter was carried out properly on the dyno day, so comparisons with DIN or SAE standards (or any previous results, even from the same dyno) are not easy. The dyno was an inertial type with a relatively light roller; this tends to accentuate auto vs manual differences. see; http://bigcoupe.com/phpBB2/viewtopic.php?t=2283&start=45 for further comments. I don't think they even used a pickup for measuring engine rpm, so they just went on the tacho reading (very dodgy). So the dyno day was all good fun but not a lot more. My own 150000 miler is a little worn, no doubt. But the compression is still absolutely fine, and it uses very little oil. Also note that the engine has probably turned fewer times than (say) an M635CSi at 110000 miles, because of the very tall gearing. Is tuning a waste of time? Well it would have been when I first got the car because about half of the senders that instruct the fuel injection system were faulty. Now they are OK and tuning is no longer a waste of time. Note that Dave's intergalactic highline (chipped) showed healthy power even with a slightly noisy bottom end. My own car goes 0-60 (indicated, so more like 0~55 truly) in 7.0 seconds dead, not too bad for an auto allegedly ~15bhp down on stock, eh? cheers
