Not on a hub dyno;)

 

Tyre pressure wont make a lot of difference on a rolling road, how hard they strap it down does though, more powerful the car the harder they have to strap it and the more power it zaps.

 

Hubs dynos are the way forward for powerful cars but i am giving SRR another bash on monday using my drag tyres, hopefully they will grip better, i dont think i will get a true reading though.

thanks mate for advise were heading up north of ireland supra skyline meet and there is a dyno run i think its a rolling road so will go with 36/38psi in rear.

The only thing to avoid is semi slick tires like the R888, as they warm up quickly and can then spin on the rollers.

 

I don't think that tire pressure makes a huge difference on road tires.

Tyre pressure will effect the readings slightly, I would go for more rather than less. Dont over inflate them though as they will heat up alot if its strapped down tight.

if its the place im thinking of its a dynapack and you need to take your wheels off, so make sure you have your lock nut remover thingy with you

Be careful dude they will all of a sudden get hot and de-laminate, happened to a set of 888's (brand new), big chunks will just fly off.
