888's pressure.

What pressure do you 888 guys start out with cold and what do you aim for hot ?

Guinness - 14/4/08 at 07:03 PM

18 psi from cold for me.

Tried 16 but got too much sidewall flex.

Forgot to check the pressures when I first got them. The tyre fitter had put 30 psi in there! Wayyyy too hard.

What sort of pressure pick up do you see at that ?

I have just emailed Toyo tech asking them what optimum hot pressure they would recommend on a sub 600kg car including driver, see what they come back with.

Don't know TBH.

I have the NE7ER's trackday on Monday, so will take some before & after pressures then!

hicost, was just looking in your archive. Your car looks like a serious bit of kit!

PAUL FISHER - 15/4/08 at 02:27 AM

I don't no what size your running Jon,but in 195 50 15 on my Indy I ran 16psi cold front and rear,once up to temperature the rears on average went up to 20psi,the fronts up to 18 psi,but if it a real cold track day,I put a extra 2 psi in the rears.

Welll we will just have to see, I have a electronic dual stage boost, with a switch on the steering wheel, 15psi Low 30psi Hi

If it rains then the switch stays at 15 and the diff lock and LSD do the rest. Once in 2nd / 3rd switch goes hi wet or dry.

I am filming the event as well as taking part so I need as much video footage as possible, so please slow down for me


I have a switch on the steering wheel too, when I press it the horn goes off........

Talking of filming is any obscure satellite TV company taking it up at all.

You trying to get me to under inflate my tyres, most are saying more than 15psi cold..............

See ya both soon, make sure you leave us plenty of room for transporter and hospitality set up. Read enough room for a instant bbq.........
