Christ no, you give me far too much credit, I had no idea they lived in Kalgoorlie now. I meant the one and only -

My engine is stock remember,no mods done.It was done in fourth,one to one and the tyre size would make a difference.On the air ratio sheet the air flow is a bit low so the air filter is restricting it a bit or the turbo is tired or a bit of both.It does drive very well though. Pat

And that's the answer.... all else doesn't matter :arms::twobeers::BigThumb:

Thats right,believe me the gas totally changes the engine,it still has lag off idle but once it starts to spool up it revs alot cleaner right throughout the rev range.It makes it far more driveable.I would like to do something about the low air reading. Pat

Tyre size doesn't matter. The gear selected doesn't matter. The dyno will compute the load against the revs of the drum.

Actually it does make a difference, unless ALL the data is inputted, which is still just mythical as tyre drag alone can make a huge difference, i.e. A/T vs Simex

At the end of the day, the figures ARE INACCURATE, especially compared to any other Dynometer, but the back to back comparison figures are accurate and precisely what you want to know, in regards to %gained

I really struggle with this concept, as you don;t think the gas and increase in HP is precisely what upping the fuel would do?:confused:

Thanks for posting the results:)

Exactly joes dyno round the corner would give a different reading again. As long as you're happy that's all that matters.

How much did the kit cost all up fitted ?

The same dyno for that matter will give different readings on different days, depending on temp & humidity. But tyre size is allowed for.

For a dynp owner to say 255/85/16 tyres will hurt output, as in the first post, just isn't correct.

Yes it is:p, most operators will tune in shootout mode, not calibrating eveything in, otherwise you HAVE to pump in, tyre size, diff ratio, gear ratio, then still it means lick, then the dyno must be cal'ed to Australian standards etc

Have you ever run back to back with different size tyres?
