    New round Icelert for NADA P6 models

    Not to be rude, but this is a post from 2019.

    Race/Rally car project car?

    I run the four cylinder. It’s not a bad old mill, from what I understand weight is about the same as the all ally V8. Piper used to do a performance cam for the 2000TC back in the day, but they are all gone as far as I can tell. I am looking at getting a regains on a hood used or NOS cam for my...

    Race/Rally car project car?

    The big problem is that the 2000 and 3500 body shells are quite different in front of the A pillar. If you want to go down the V8 route you might be better served by finding a donor 3500 shell. I have a 2000TC that I use on the track for fun. The big thing that can help these cars are: Stiffer...

    Etha-guard classic E5 E10 petrol.

    It’s a possibility. I did notice that rubber swells and goes gummy when exposed to E10 fuel.

    Etha-guard classic E5 E10 petrol.

    I believe it’s a stabiliser. Used to stop ethanol forming varnish if left in a tank over winter. Ethanol based fuels have a tendency to absorb water which causes them to break down over time. This is meant to reduce that. The other issues of ethanol is that it attacks old rubber fuel lines and...

    Dash repair

    Very nicely done. I used a crack repair kit on mine a few years ago. It’s looked great until a couple of months ago and it’s cracked again. I think the vinyl from Woolies would be the next step.

    Going a little in depth with the front suspension

    If you wanted a collet style clamp I would rotate the hex 90° (as it was originally) and put a slot on one side so you can still use it as a clamp. That would optimise surface area and structure equally.

    Going a little in depth with the front suspension

    Two thoughts on the shape of the mount. (1) Having the points of the next top and bottom creates a large stress riser. (2)Unless you plan to weld or heat shrink it onto the bar ends it’ll be rattle city and will wear loose quite quickly. I’ve used a slightly higher spec than original torque...

    Going a little in depth with the front suspension

    Which is pretty close to the standard setup. I believe it’s in the region of 2x the diameter. I’m using grade 8 UNFs as per original threads.

    Going a little in depth with the front suspension

    The ARB I made has 17mm hex ends as per the original bar. That ensures a good amount of clamping surface area between the clamps and bar. The exposed center section of the bolts isn’t really any different than if the clamps and bar were perfectly aligned without gaps. The screws would still be...

    Going a little in depth with the front suspension

    Class 12.9 is a metric spec. These are UNF bolts. Grade 8 are good, but can crack in a failure mode due to hardness. Grade 5 actually might be better for this application as the have a small amount of give in them that allow for a small amount of preloading when torqued to spec.

    Going a little in depth with the front suspension

    That sounds about right. Next step will be stiffer springs on the car. This will add support which will most likely reduce torsional loading by reducing suspension travel relative to both sides. I like the idea of stepping up the thread size next. I’ll most likely do that at the same time as I...

    Going a little in depth with the front suspension

    Dyslexia got the better of me. 4340 was used on my car. I did get it flame hardened to (I think) 65 Brinnell to add to stiffness. It been in the car for around six years now. Certainly helps with body control. I would say that going stiffer might be a problem. I used loctite on grade 8 bolts for...

    Coolant Temp Gauge Stays In White Area

    I would ground the temp sender wire first. Just to ensure the gauge goes full hot. Want to be sure the gauge is accurate.

    Going a little in depth with the front suspension

    Yep, this is exactly why I’m doing this to accurately ascertain the wheel rates. Bear in mind that the arrangement with the front suspension means that the increase in load has a lower impact on creased spring rate under deflection. So, 160lbsf/in should scale to an extra 160 lbs of 1” spring...

    Cam locking pin

    You can reajust the valve timing to spec using this method. Rover design the cam sprocket to allow for just this sort of thing. Here's a guide to how: Valve timing fine adjustment

    Going a little in depth with the front suspension

    Yep, I need a few each hours a day to reverse engineer the scan and set it up in an assembly. I'll post an update as soon as I have!

    Going a little in depth with the front suspension

    @Gargo Really interesting reading on your spreadsheet. what material were you referencing for the ARB? I'm running 4043 steel 1" Hex bar flame hardened to 65 brinnell (IIRC, made it a good few years ago. The spring vs wheel displacement is very helpful. How did you calculate the front spring...

    Going a little in depth with the front suspension

    Thanks for this @Gargo I was familiar with the concept of having a slightly higher frequency spring for the rears to deal with follow through on bumps. But this adds some very helpful details. When I get a chance to use my laptop I’ll grab your data and take an in-depth look.

    Going a little in depth with the front suspension

    That makes sense. The springs measured were used 50 year old ones. So the 10-20lbs lower rate would make sense.

    Going a little in depth with the front suspension

    The standard rears I measured at 240lbs/inch. Need to take some measurements to work out the wheel rate next (Not to mention compression when at rest vs free length)

    Going a little in depth with the front suspension

    Good point on the unsprung weights. I did calculate those before with estimated weights for the unsprung components. Here's the estimated weights I put together a while ago and forgot until you mentioned this :) To your notes on ARB's etc. Beryl already has a 1in Hex 4043 flame hardened...

    Boom Boom! Me too! If you decide to do more in the future let me know. Hapy to play with this more.

    Going a little in depth with the front suspension

    As some of you know I'm playing with making adjustable spring seats for Beryl. I've already made the ones for the front, and will need to make the rear ones soon so I can fit them all. I've been chatting with @cobraboy about his findings when he built his Group 2 replica. This got me thinking...

    Getting back on the road

    Finally had a bit of time to give Beryl some attention this weekend (more on the suspension stuff I’m playing with at the moment later). I’ve been very happy with the HIF6s and the 2200TC airbox on Beryl. However, the internal edge of the intakes from the airbox to the carb mouths has a sharp...
