The oil level wont affect pressure, unless its got none. Most cars can hold more oil than what the dipstick says without any drama. When I rebuilt mine I cheeked it out and it was something like 10-15mm over the full line. In the HQ we run 1" over.
Oil catch can has nothing to do with it, its for catching blow by

In terms of insurance value
Your car wouldn't be much more then. 7.5k

Whether you can get 10k is a different story.

But
I would put money into oil cooling and a catch can.

Also in terms of a sway bar
One reason a car hndersteers is that your tyres are not on the ground properly so it under steers
And bigger away bar up front will help stick your tyres to the road harder rather then let them come unstuck in hard cornering
Many people have confirmed a lot better traction and less hndersteers with a larger front bar

White line do a good. 3 way adjustable one

Each to there own however :)
Good luck with the baffling be interesting to see how it goes.

@MCT cool many thanks for the data log. Not sure if I'm reading it right but it looks like the oil pressure is dipping to 0 kpa (grey line) that can't be good
 
@ Gates: Pretty sure most of the understeer was due to stock suspension on semi's. And alignment needs to be more err...personalised. Changing driving style also makes quite a difference since I had a habit of late braking. With RE002 and same stock sussy I actually had a much more balanced setup since the tyres and sussy was "better" matched.
You are half right about the front sway bar. "By the book" front sway will increase understeer since it stiffens front thus increase rear grip. The ones who exp less understeer was cos they had too much body roll so the front sway helps that. But since the sway bars connect one axle to another it reduces wheel independence. The point of modern suspensions is to increase wheel patch as you say which is why they did away with live axle for MacPhers and double wish, no? So instead I will try to run higher spring rates which keeps 4 wheel independence but keeping the stock sways for now. If you remember Ken's car (FZero) he actually runs no sway bars lol
The good thing about the sway bar however is that it doesn't compromise ride comfort as much as spring rate.
 
Anyways before I delve into sways I should really try my rsr/koni combo first as I would have a better idea on where to go. Still waiting on the rsrs to arrive but thanks for the tip mate. I'll be curious to see what u run down the road and how it compares. I don't have the time and money to track the car soon but next trackway I'll definitely know if I need an oil cooler from the oil temp/press gauge :)
 
Thanks for the FYI Trav but don't race teams rebuild engines after each race hehe (i really have no idea)
 
Oh and since we are on topic about engine wear, in addition to pre-oilers, what about block heaters? Then switching to 0W-40 oil I think engine wear will be a distant memory LOL

^Precisely, the semis were just too grippy for the stock suspension.

Yeah i think your getting to ahead of yourself Tri, an engine pre warmer would not be required, altho I would be lying if I said I never wanted to have it on my car ha ha but not required for a stockish motor as 1. your engine was designed to start cold, i has done so very well every day for 20 years and 2. your not required to have your car turned off at the track, then start it up and be racing within a few seconds, you can idle for a few mins.
 
If your a F1 car, v8 supercar ect then thats different, as especially with F1 engines the tolerances are very tight, at room temp the motor might not turn over or cause alot of friction on parts and damage. A v8 supercar needs to sit there, then start the car and go do practice or qualifying runs ect.
 
I dont know about F1, but V8s and alot others use off car coolant heaters, 2 dry break fittings on the coolant system, connect up, recirculates coolant and heats it up, heating up the motor, oil ect as it goes.
 
Now if you had a dry sump........ you would be silly not to wrap a nos bottle heater blanket around the large oil tank in the boot, and have a power supply off the car to warm it up :)

Re Upgraded sway bar
Tree - I run Pro Kits with Konis and also use 595 RS-Rs and a Whiteline H/D front sway bar.
Before fitting the sway bar, if I went too hot into a corner I would feel the back would want to "come out" and just a general scary feeling. After I fitted the bar, there was no noticeable increase in understeer but just a feeling of a more planted and stable car overall with much less roll - the front end felt much more "connected". Only if I really yank the steering wheel hard into a very tight turn will it understeer but so will most cars. I'll have to point out that it's only set on the 'soft' setting so I can't comment on what it's like on 'normal' or 'hard' which would probably induce more understeer.
Now I'm willing to upgrade the rear bar and see what that does.  

there is an accusump I just got in for a customers car, just for reference tree.
this one is a monster 3l model.

I find it odd that everyone is so quick to dismiss oil surge on a mid engined car. the most common mod you will find on a lotus elise/exige that gets tracked is an accusump.

oh and tree, your correct, the engine ran for 3 seconds with no oil pressure whatsoever on that one corner.
