    windscreen rake?

    Assuming FW rear body work, then 970 sounds about right, see here...... http://forum.wscc.co.uk/forum/topic/116627-ste-hs-mega-s2000-build-thread/?do=findComment&comment=1313967

    North West Convoy to Stoneleigh Sunday 6th May

    Not really had chance to get out on the Westfield since IVA in October, only 250 miles on the clock! But planning to join the Convoy at Knutsford in the morning. Looking forward to meeting some new faces, just hope I’ve bolted it together ok! See you in the morning!

    Perhaps offer the exhaust up and see what clearance is left. If you’ve got the gearbox mount aready bolted down, then it’s not really going to move forward at all. You could take the gearbox mount bobbins out and see if will go any further forward on the engine mounts and if it does, slot the gearbox bobbin mount holes. Of course there could be some “tolerance” in the manufacture of the manifold which isn’t helping. The engine is pretty solid on the mounts though so probably not a major issue.

    I suspect those measurements were given as a guide before the chassis had mounting holes pre-cut. Measuring those dimensions accurately is difficult and to get it mm perfect also very difficult. I don’t think mine would actually move around much on the mounts even though the holes are slotted. Best bet is just to manoeuvre it as best you can to get as much all round clearance as possible. If you can move it forward at all, it will also help clearance round the bell housing.

    It is quite tight there but I was able to make a heat shield which wraps round the diagonal with enough space for the exhaust to still fit. Best photo I’ve got to hand.... Will the engine slide forward at all on the mounts? Even a couple of mm might give a bit more clearance.

    Ste H's Mega S2000 build thread

    So spent a bit of time figuring out what’s going on with the S2000 gearbox speed sensor setup. There were a couple of possibilities: 1. The RT pulse divider device couldn’t cope with the frequency of the signal coming off the sensor. I looked at this on the bench with a signal generator and a scope. Putting a signal in at 6.2khz which would be the equivalent of doing about 150mph, the signal came out of the divider perfectly indicating that wasn’t the problem. 2. Something was happening to the signal from the sensor as speed increases. To test this (with a bit of help from my gurus at work) we setup a dual channel scope, one channel looking at the signal coming off the sensor and the other looking at the signal going into the dash. Then went for a drive to see what happens. It turns out that as speed increases, the voltage output of the sensor gradually decreases from above 3v at 15mph to below 1.2v above about 45mph. The pulse divider needs a signal input of at least 1.8v, hence the output to the dash just stops above about 45mph. No idea why this happens, possibly something to do with capacitance apparently, but I dont understand that - and don’t need to! So to fix the problem I consulted my gurus again to come up with a little circuit to pull the signal up so that there is always a strong signal regardless of speed. The first circuit didn’t work but the second one using a transistor, couple of resistors and a capacitor does. Tested to the highest legalish speeds I could and it works perfectly. Here’s the circuit used: In hindsight doing it again I would design, or rather get my gurus to design, a circuit to do the pulse dividing and pulling up of the sensor signal. This would probably cost less than a couple of quid in components rather than the £100 pulse divider from RT. Anyway, hope this helps anyone else looking at going down this route.

    I agree! I need to work out where the issue lies, it can't be that difficult!

    Hi Rich Yes, I guess it would but..... I currently have a problem with it, in that once the speed gets above about 65mph, the speedo stops working. My guess is that at that speed, the pulse divider isn't able to interpret the signal from the sensor and is seeing it as a flat line rather than pulses. Race Technology believe the pulse divider can cope with the frequency so are blaming the signal from the sensor. For the time being I have reverted to the wheel sensor so that I can drive it. I need to revisit this and look at the signals with a scope to figure out what's going on and then come up with a fix, just haven't had the time. I will get to it eventually though, because as you say the standard sensor isn't the best. I'll let you know if I come up with anything. What's the maximum pulses per mile the standard speedo can be set to? I doubt it will go this high, but if it can be set to >150,000 then it could work without the pulse divider.

    Excellent, well done

    The tube on the passenger side is smaller than on the driver side. This is to accommodate the Mazda diff which sticks further forward on the passenger side. So it is normal. What WF haven’t done is change the design of the tunnel side panel. I had to trim the panel a little to fit round the diff, but you would be better to just trim the panel flush with the tube. If you are going to drill and rivet the panels into those rear tubes you will need to fit them before you fit the diff. I had already fitted the diff when I came to fit the panels, so just bonded them along those edges. Tightening the diff to prop bolts was difficult enough with no tunnel panels fitted, don’t know what it’s like with them fitted.

    Is that not the rear tunnel top panel? I had small blanks which were just the shape of the holes for the left hand end panel.

    Does the battery voltage drop if it’s not connected to the car? Might be worth checking overnight with it disconnected. It will run down quicker with some load, but if it’s dropping when not connected then it’s knackered.

    Dash 2 purchase

    I enquired about getting battery voltage displayed on the dash and setting alarms with RT. They confirmed that the only way without Ecu interface is by using up an analog channel. As I’ve used all 4 inputs already they offered me their ANALOG8 at £222 which provides 8 additional inputs. I’d be tempted but can’t think of anything else to put in the other 7 inputs!

    Great, glad it’s sorted. Best of luck for Monday!
