Recap of the English F1 fleet - Take 2...

Cool, so is it the loudest allowed? I seem to remember there being different stages of exhaust you could do for customers?....

[Peloton25]

I'm sure I have given credit to Quicksilver for these systems more than one time in the past - I'll stop doing that.

Cool! Right exhaust looks much more shiny then the left...

[M.S.O]

We were halfway through polishing them up before first startup. If you leave fingerprints on the titanium when the exhaust first starts up they are burnt onto the surface and stay there!
This is almost the loudest we do, the 'Goodwood' option is to modify the standard box and is a level below.

HOw much different is the LM's exhaust compared to this #028 currently added exhaust system?

[webslinger283]

Does anything in particular need to be done since this is a road car that no longer has the rear crumple zone (i.e. no huge silencer to absorb the blow) to keep it's crash test certification? I know people can do modifications like this on their own, but since it is a McLaren installed system i figured it had to at least have been thought about.

[M.S.O]

The exhaust is very similar to the LM system. The LMs were homologated with this type of exhaust so no problems there with crash certification etc.

[Peloton25]

Any idea why the catalytic convertors on chassis 024 have been altered? They're quite a bit fatter and somewhat shorter than the standard ones. Possibly part of someone's US EPA conversion methods was my thought, but certainly there are other cars here that preserved the originals.

The siamese pipes are non standard as well and a heatshield missing. It will almost certainly be EPA fiddling, there has been weirdness on other cars as well that we have seen including air pumps and additional whole vehicle wiring looms on some occasions!!

[Peloton25]

Yes - here's an example of the air pump that was fitted to chassis 068 when it was Federalized.



I believe the efforts here on this car were what finally convinced the DOT/EPA to expand the eligible model year range on F1s under "Show or Display" from 1993 thru 1995 up to 1998, to include all the cars. This car was done by JK Technologies with final signoff from the EPA on Sept 25th, 2003.

So silly they have to even waste the time and money for this - the 'Show or Display' exemption should have been written to overlook all EPA requirements as well for the incredibly small numbers of cars that were going to be qualified under it. Just a few more years though and we'll be at the 21 year mark where I am fairly certain emissions devices won't need to be fussed with any longer with new arrivals.
