Xflow to R1, a couple of questions for starters
Starting to plan my swap for the end of the season and have the following questions so far, I know there will be more as I start but I want to plan as
much / do as much / get as much as I can before I start to make it go as smoothly as possible.
Any advice gratefully received.
Headers / link pipe:
Will want some stainless ones and a link pipe to my existing can making, who makes them, can you get them of the shelf or is it a matter of taking the
car to them, roughly how much?
Prop:
I have a fixed diff so I presume I don't need a sliding joint, are one piece or two piece best? Is it best to have a rubber donut thingy in
there somewhere? Who makes them, roughly how much?
Reverse:
I need a reverse to stay in my class when sprinting, electric would seem the way to go, I'm not that bothered about it been that effective just
as long as I can prove it works. I've seen some on the net at ~£350 seems a bit pricey for a starter motor and a gear, has anyone seen any or
made any good cheaper options? Who / How / how much?
Diff:
My existing (english) diff is a 3.9, I run 185/60/13" at the moment, I can appreciate I may need to go up on the width but want to stay with
13" what diff ratio will be best? (don't spend ages on motorway)
Gear shift:
I've read that the position of the shift on the R1 makes paddles an easy option, I can appreciate every application is different but has anyone
got photo's
Air Filter:
I'd prefer to keep it all under my bonnet but I doubt this will be possible, i've seen some cars in pics which have, how is it done, what
options are available? If I go for a foam filter what effect will it have, will it need re jetting? Do bike installations need jetting anyway?
Power Commander:
What are the Pro's, con's, cost of these?
Fingers are sore so i'll leave it at that for now.
(I've tried some searches and found bits of info but nothing conclusive so far)
TIA

Hi,
Headers:
There are a few companies out there that may be able to make them to suit (you haven't put the model of your car down to know for sure!) MK
Engineering is one name immediately springs to mind.
If I was to recommend anyhing about exhausts, I would say that this is one area that's worthy of spending good money on.
Prop:
Sorry for a question as a reply, but if you have an english diff, doesn't that mean you have a Live axle?
If it does, that would mean that your diff isn't fixed so you would need the Slide joint at the back.
If it is fixed like a sierra one, then the Slide joint will be at the front.
Reverse:
Just make your own - not done it myself, but a cage to hold a started motor with a slide action to engage a large cog in between your prop and diff
shouldn't be too difficult.
Diff:
Your 185 tyres won't be too bad for grip.
Your 3.9 ratio diff will be wrong for most bikes. A 3.6 is next best, but less than 3.5 would be preferable.
GearShift:
Just because the gear spigot is where it is, does not mean that you need to go for paddle, I'm about to make a conventional gearshift for
someone's R1 engined car and I think it will be quite a nice system.
Air filter:
Stuff your bonnet line and stick the existing bike airbox on - it'll save you money and it will ensure you'll get on track for noise.
May need jetting, but can only answer that with a few more details!
Power commander:
What engine are you fitting? Or more to the point - is it injected or carb'd?
Anymore Q's - ask away!!!
Steve

cheers steve, car is a narrow bodied westfield, the diff is fixed, its an english diff in an aluminum casing, similar principal to the sierra. had a
bit of a look at cwp's and looks like best i'm going to get it 3.54:1
re gearshift, i quite fancy a paddle shift but its not the most important thing if its a ballache
i'm planning on fitting an injected motor, 04-06 iirc
Thanks
Andy
