I am bored of my alu painted exhaust manifold and want to get the heat away from the bay a little better. I always loved the wraps but never really thought it would work on anything but the artwork that is the 16v manifold. Does anyone here have exhaust tape on a 8v or better still 12v 190 ? Or a pic of someone that does ? I guess a pic of something similar will give me an idea of how it handles the cast corners and seams. |

I doubt it is very effective on a cast manifold. Cheers Bri |

Its got to be effective at stopping it look like a twiglet  seriously though, if it insulates the outside of the metal from the engine bay its got to help transfer the heat downwards to beyond the tape ? ie, the down pipes and the bits that get better ariflow. Hasnt it ? Its obviously not gonna look that good and wont work as well as it would on a free flowing system but I still feel it may help ? Slightly ? possibly ?  Brian do you happen to know any tubular options for the m103 other than custom made ? |

I've had a few quotes for a tubular manifold... Scary, to the point of completely forgetting the idea. |

Couldnt philj fabricate one up? The 16v ones are around £1500 from mb

I wll speak/type to phil I guess, I need new downpipes anyway may as well go for the twin pipe, twin box 4 pipe system Can anyone remember the user with a white car and twin rear box (4 pipes), it was at retro but my pics didnt come out. |

I'm looking into making A small batch run of mandrel bent stainless steel 4-2-1 tubular headers (with or without sports cat) for RHD M102's shortly, unsure of the inline 6 but im sure its not impossible. Richy. Edited by Richy190E, Sat Aug 1, 2009 10:01 pm.

cheers hiten, I want to dig out some pics..... richy, do you have a very rough idea of cost ? perhaps initially of the m102 version ? The m103 would be a 6-2 as it would run down the car as 2 pipes. |

It would be 2x 3-1 then :p, im not sure on costs yet as mine will be used to build the jigs up (the expensive bit!!) not much longer though, if I get a set of exhaust gaskets for a 103 i can work with that and modify my 102 jig to suit, and work around the steering box. Rest assured they will be top quality as the guy who is making them with me has built formula 1 manifolds in the past. |

early stages mate, certainly dont go to any significant effort, the chances are my gyp factor will kick in and I will just repaint mine At some point I will actually get around to fitting the supercharger so at that point it will become more urgent. And yes, 2 x 3-1s

Due to the space, getting the tuned length may result in one big, long, 16v style bunch of bananas! Im currently accumulating data based on cylinder heads on the m102&3. And i'd rather go to the effort and produce something useful than cobble something together and pass it off as the real thing. Besides my mate wont entertain it as its his reputation on the line also. Plenty of noise will be made come launch time lol, I may need somebody to evaluate the m103 version for me once its made. |

Will it be tuned to the stock m103 ? Remember I have the 3.0 and it wont be long before the supercharger is fitted so it may not be much use in terms of developing the ideal 2.6 manifold. |

Forced induction IIRC requires free flowing so yes it should be suitable. I will however look into that for you. I may need compression ratios and boost pressure figures from you but I think it will b fine. |

Is the 3.0 an overbored & stroked 2.6? If so I can look at the difference in terms of bores etc because not much will change in terms of cam timing etc just cylinder capacity, unless the valves are different sizes to the 2.6. |

As far as I know the valves are the same, its certainly the same rocker assembly although I guess thats not a guarantee. I think its just bored and stroked, I can find that out. Its a stock , m103 from a 300e (the higher bhp version of course ). As I say, dont go nuts with a calculator, if a cheap easy option arrives I will take that Remember this started out with advice on £15 tape from ebay Boost figures will be hard to get hold of but its a pretty low boost, I can get a rough figure when the charger arrives, the head has been skimmed too so figures are not easy for me to get hold of but I guess you dont need it that accurate ? |

Ok well I will see what I can come up with and let you know somebody's bound to want one sooner or later and it would be nice to roll out a range of manifolds.

id be interested in a 6 branch extractor manifold for a m103 2.6 if theres any gains to be had in torque or bhp thanks |

Kenny Have done some research, and this company seem pretty good. Prices for a cast manifold are very reasonable. http://www.camcoat.u-net.com/Exhtprices2002.htm |

Hi, @ bri957, that link is the prices only for 'Coating' not for the prices of a 'Manifold' or am I reading it wrong ? |

Longest build time in history?

I think you are reading it wrong, obviously you supply your own manifold. Thank you for the link by the way, i'm definitely going to get mine done i think. Any opinions on whether you should use heat wrap too? Heat wrap degrades over a few years so you'd have to do it again, this should last a lifetime. |

After adding the heatwrap you can coat it yourself in silicone hi temp spray. It makes it last far longer. I have only just done mine so cant be sure how long it will last but it seems pretty good so far. There are pics in the 'what have you been up to on you 190 thread' |
