The spring that holds the thermal pellet was also installed...  It is not needed.  In itself that would not be a too much of a problem, unfortunately it was installed on the bolt side of the pellet replacement holding it against the opening of the eshaft, restricting flow. Lesson learned...

Really? Damn... :(

It was already ported, side plates had some wear as I had lapped them but not re-nitrided them,  they are paper weights now, I knew that was going to be an issue but was interested to see what the wear rate was as this engine was always a test mule.  I have a new engine I have been building up that I have re surface treated the side plates so that should avoid that problem next time around.  Rotors are good (new bearings needed), rotor housings are fine as well (plenty of oil for them!).

I'm not too bothered a simple mistake that I wont make again, this is how progress is made.

Manged to pick up a cheap bosch 413 (It's the bosch motorsport version of a 044) from a motorsport team sale and a new one way valve to see if I can keep the fuel system pressurised pump off.  Apparently it was part of a fuel system for a Saleen GT car, not sure I'm going to be using it to it's full potential #overkill !!!

Got the extension on my steering wheel to move the wheel a little closer to make it a little more comfortable...  Need to see if I can work out a way of moving the gear stick another 20mm towards me.  How did you handle the gear stick?  I seem to remember that you engine is alot further fwd than mine.

Ordered all the pre-requisite number backgrounds, novice sticker and so on to meet blue book.  Need to make my detachable timing strut this weekend so I can switch between sprint and circuit mode.  Had a chat to the local scrutineer (turns out he lived just over a mile away!) he is poping down to take a look over the car from me, also found the car has a MSA log book already so just need to send that of for a number of ahem small updates.

Most of the loom stuff has arrived, so I will have to start that job at some point (not looking forward to that) but it will solve the electrical gremlins.

Oh and I need to get the diff out so it can go get its new CWP,  that is a Feb job though.

Might sneak off for another test at the end of the month once the new fuel bits are in to see if we have solved the top end splutters!

Oh and I need to order two sets of slicks, one super soft for sprinting and one not quite so super soft for circuit work (ouch).  What size, compound did you go for?  I'm assuming you went radial slicks?  I know some of the light stuff still sticks with crossply for compliance, seems a bit old school to me?

1. gear stick i put a Set in it. ( right bend straight then left bend). soz just incase you dont know what a set is...got a gearstick extender from ebay with correct thread and heated it up and bent...got 2 i done happy now. slightly longer throw but closer to steering wheel.

2. Tyre yes radials Yokohama a005. 200/580/13   meduim if my memeory serves me correct. mine have had little use nearing 2 years old now...immense grip when warm.....and oil surge! between centre iron and plastic filler pipe there is a flange... put a penny washer in there...makes filling up a pig but stops the oil washing out of the sump on right handers.

The gear stick make sense, I really don't need much as it is only 3rd that is a little bit of a push, maybe I will try for a bend in the end of the standard lever and then a small extension to bring it back a little...  I'll take a look at that.

I'm running 13" compo-motive minilite's...  13x10 at the back 13x8 up front IIRC...  I don't have any caliper issues, M16 front calipers and Westfield (HiSpec) rears.  What are you running that is so tight?  Do you use vented disks?

Thanks for the heads up on the slicks.

Solid discs all round. 7j team dynamics all round...rear was issue with hand brake lever on the sierra rear calipers. Wilwoods on front...braking no fade plenty of bite. Ill be going wide on rear. compomotive had changed chinese foundry supplier and had zero stock so i had to buy the team dynamics as a compromise.

Ah, I have no handbrake so that is probably the difference.

Yes that was a pig as well to sort..whole cars been a pig tbh! Lol its gotta mot so great for sunny afternoon blast.
Fast pig though!
Serious about the oil surge though. Fast right handers on slicks it will come up oil filling spout. Ive know got an rx8performance sump from the states its gated for antisurge. Oil surge took my engine out.

So in the centre plate the is the oil fill hole (a short round pipe with two threaded holes either side), that bolts to a (in the case of the RX8) plastic filler tube that puts the oil fill in a (not so) handy place to aid getting oil into the engine (it also has a breather).  Put a washer between the two parts to restrict the oil travelling up the fill tube by restricting the size of the orifice.

Does that help?
