I thought they are better cos they look good and are new

Ive found where i read it. Its in this months issue of radio race car. Page 104 i think. It says its to minimise the effects of temperature change. Have a read

It must be correct then if it's written in there.


BTW, I'm just off down the chippy for my dinner. I read in the paper once that Elvis worked down there and I'm a big fan of his! :woot::woot::woot:

And tonight I'm going to get my telescope out to look for that double decker bus on Mars! :woot::woot::woot:

Would have a read if I could get it :(

All i want to know is How Much & Part Number :thumbsup:

Will they make me faster - doubt it
Will they make me drive better - doubt it

Will they be shiney and new - absolutley :thumbsup:

Any ideas when these will be available seperatley ?

Quite possibly over 5 mins, maybe not over a single lap.

Not being an expert in thermo-fluid dynamics or anything, or not having read the article, my guess is that the temp changes you are referring to are due to friction between the oil and piston and also turbulent particle flow of the oil through the piston. Logically the increase would not be as great in the big bore shock. However, could you actually notice a difference in viscosity due to these effects between the 2 shock types over a 5 min run? Very unlikely!

Load is spread across the larger piston and oil and therefore a more consistent feel is met, yet the pitch feel can stay the same.

I'm no expert but I have been hands on with Grants car and we have tested a number of things. I rounded his pistons which helped in certain conditions.
Hi Trish,

You mention rounded pistons in certain conditions, what conditions?

I assume the starting oils for the EPR, RHR and Stofold etc. must be higher now.

Why? :confused:

I like the normal shocks as you dont need to put as much oil in them so you are saving money.:p. But I am a tight arse LOL.

Yer, just gone back to do some rallyx, bought an MP9 OMG the shocks are huge:woot:, I'm going to be getting shock oil in 5ltr cans soon:D

I thought people run thicker oil with the big bores etc.

I know there is the pistons element.

Until I get them I'm just trying to get the set-up direction in my head.

I ran 40w 3 hole drilled 40w in the front and 30w in the rear drilled again at EPR. So potentially 40w front 6 hole, 35w rear 4 hole?

with the clocks changing this weekend pending whether the Cat SX2 is released next week I'll have to do some evening testing at our local track next week and the week after..


I'm probably miles off the mark with my thoughts :( Give me computer stuff and it's easy!

Northy 26-03-2010 03:19 PM
I'd just wait until the team guys start releasing set-ups ;) But I don't think you'd have to go any thicker on oil.

mikeyscott 26-03-2010 03:21 PM
Yeah that's what I'm going to do. Just trying to figure things out for myself :( and not doing very well.

Cheers,

mickey once u get ur big bores we can put u right on the oils pistons and springs. we are running same sort of weightt oil at the mo and messing around with piston holes and sizes if any thing with the big bores u can run lighter oil and still get the pack . because with the standard shocks we ran thicker oil to try and get the pack we needed.

Cheers,

I thought I had it the wrong way round and the above makes more sense :)

Looking forward to trying them at EPR on the 11th if they are out etc.
