The x-flow engine position was *wink*I think dictated by the width of the existing bell housing. It cannot go back any further with out fouling the foot wells. To get the gear stick back a little further there is a 30mm spacer plate between engine and gearbox. The Vauxhall and K series bell housing were bespoke so could be made that crucial inch or two narrower which allows the engine to sit back a bit further - spacer no longer required and gear stick 50mm+ further back. Requiring a shorter propshaft no doubt. It shounds like you have the raceline exhaust - if you have their engine mounts surely that would confirm it. Nick

The reason I was thinking of the GT6 disk was a vauge plan to use a Willwood caliper on a custom bracket. Given the custom bracket can be made to any shape I was interested in oversize cheap bolt on disks that could be used instead. Does anyone know of a place to research disks - that is where they list offset and diameter and PCD rather than listing the make of car they came off? Nick
-
Ah now that would explain something that was niggling me as I wrote it. Cagey There is another disk that is a little bit bigger that would bolt in its place (for use with another caliper) can you remember where that disk is from 🤔 Nick

Which come off a Sierra XR4i 🤔 or any Sierra 🤔 either way there is no substitute for plonking an old one on the counter and asking for another one 😳 Nick
-
SWMBO clio developed a clonking from the left rear associated with coming on and off the throttle. (while I was driving 🙆🏻) The exhaust had come unhooked from the rubber hanger. - all quiet again 😬 Nick

Joe So you can explain to your mates If at the end of the power run just as you hit maximum revs you depress the clutch, the engine/gearbox/tyre/rollers will slow down. How fast they slow down will show what power was needed to speed them up. These transmition losses can now be added to the at the wheels power to give flywheel power It appears through re-flashing the ECU he had full control of fuel/spark/cams - If he had a play with the cam timing did he get a worthwhile increase in power/torque or it the design of the system more geared to getting a cleaner idle and emissions 🤔 Nick
-
Did they do a rundown test to get at the flywheel horsepower? Also I noticed that you had variable valve timing I did not realise that they did that on the zetec (same zetec as is in the focus) Do you have an ECU where you can play with that 🤔 Nick
-
Well I am feeling stupid driving to the one on the A308 😳
-
Bruce Yes, did mean paralelle to ground "Fully loaded" maybe stronger springs? seem to recall that Angus and tessa found that the great setup for the track struggled with tessas shoe collection in the boot. Do you have the progressive springs (unequal windings)? I am not sure how good these are - but may help.
-
I understood that to get best geometry on the front suspention it is best to get the lower wishbones horizontal. The rear rake can then be worked out from there. If you really need more ground clearance maybe looking at increasing wheel / tyre size may be a better way then jacking up the suspention into a Caterham CrossRoader Nick I think you have to measure the diameter of the adjustable platforms to get the corret spanner.

Jeff is the AIM listed spec of a "VDO Oil pressure sender" going to match what has been on your car for the last 15 years? I would guess possibly not. either through age or change in specification. you could try to remove a sender and put it in boiling water and see what it reads. Nick
-
I could well be Tony 😬 I would be interested in which one it is although any stack rev counter will be overkill for the car - it is just weather it will work in my car and within prezzie budget. Nick nickpcallen(at)gmail.com

The delightful Ms Doh!Nut has suggested that a new rev counter might be appropriate christmas/birthday gift. I have a rather old one 😳 that only goes up to 7K Given that the rev limit is 7500 probably explains the floppy needle I am currently getting. 😳 So X-flow Weber Alpha injection currently single coil - soon to be wasted spark distribuorless. Is there anything I really should or should not have 🤔 I fear budget will not stretch to a Stack one so something more modest. Elliot perhaps 🤔 -any opinions 🤔
-
30+mpg from injected x-flow as has been said 3D ignition will get you nearly there for much less cost. Nick
-
Dont re-use the oil that has landed in the breather catch tank. My opinion on oil is that any good semi-synth such as Magnatec is fine just change regularly. Other opinions will differ Nick
-
I did see a comment on an ebay item (unimpeachable source there then ❗ ) Some one was selling a st170 as a Duratec. A buyer commented that the Focus st170 is not an alloy block it was a "Duratec head on a zetec block" Which begs the question - would the zetec head fit the right way around on a duratec block 😬 Nick
-
Myles I dont understand why you would change the 5th gear. 1 it costs as much for a big change in ratio as a small one so the increase in performance for the change between 3.8 *arrowright*4k at 80 is minimal and you get some little extra annoyance on the motorway. 2 There are few places to use speeds that 4th cant get you. 5th therefore is a cruising gear that should be as high as possible. It will be quieter and will use less fuel. This simply makes the car more usable so you can reach further flung country roads. Nick
-
If you start thinking about really drastic mods to your manifold remember that a DCOE must be kept within 4 or 5 degrees to the horizontal or the float chambers/ needle valves wont work correctly. Nick
-
If it helps anyone the very early DeDeon had a narrow butress that was in 2 parts. The different style of A-Frame went inbetween the two butress' Without measuring I would say the base is 8 inches accross rather than a foot or more for the newer version. Nick
-
The "Two maps" bit might be a little optimistic. All you need is a spare input which adds or subtracts fuel and timing from the main map like the temperature correction does. Nick
-
The problem was originally with the drivers seat, which has now been swapped with the passenger seat, which is now out the car ready to be fixed.
-
I prefer it from above 😳 removing the air filter can help the view if not the access. My curious misfire was cured by a new dizzy cap propperly clipped and ziptyed in place. Nick As an aside my crossflow has taken to doing the same but I think it is the temp sensor adding too much fuel as it thinks the engine is cold.(not applicable to you) popping and banging was reduced by shoving some beer can segments to seal the gap at the colector which kind of worked by reducing the air for the excess fuel to burn but not a complete solution. but could your choke be adding too much fuel 🤔
-
Stronger and maybe a little lighter. It depends also on the spec of the rest of your engine, If it is just a supersprint rebuild and you are sticking to 6000 rev limit then they are maybe not worth it but if you are thinking of building something more exiting and thinking of 7000+ then they are increasingly worth it / compulsary. Nick
-
the seat runners move more than 5 inches so even if the difference in your heights was all in the legs (bit freaky 😳) then you really should have a problem. However I suspect it will not be perfect for either of you. Nick ps sewing a MOMO label onto a cusion increases its acceptability 😬

I am getting the feeling that the absolute cooling capacity of a system is independant of the SHC of the cooling medium Low SHC high temperature gradients High SHC low temperature gradients but (within reason) the net effect is the same. The higher SHC just acts as a buffer to dampen the temperature variations. prepared to be corrected Nick
