look very very good buddy
I so have no idea what all this turbo larky all means. Looks nice tho! I thought you weren't worried about bufty?
when it's probaly free who gives a **** lol
Technically i got paid for doing it :dQuote:

Looks top notch!
Yeah, a smaller turbine wheel (compared to the full audi unit/the comp wheel) is effectively geared more like 1st gear than 3rd, so for a set amount of exhaust flow it will spin up quicker, so less lag at x amount of boost. From what I understand the upper limit of the pressure the turbo can deliver on that engine will be slightly lower than a standard vxr turbo, because a smaller wheel is effectively less leverage? But it will spool up quicker for anything below it's max boost.Quote:

Cheers Adam, yer i'm using a standard corsa vxr turbine wheel with a 225bhp audi TT comp wheel.Quote:

As i'm using the standard vxr turbine wheel with an enlarged comp wheel it can't deliver less pressure than the standard vxr turbo.
I figured it would deliver more flow (and earlier too, which is the reason for doing it, to reduce any turbo lag?) but at a lower max pressure? I.E if you closed the wastegate on the vxr turbo and let it just go up to whatever pressure it could manage, it would be higher than your hybrid, as you're turning a larger wheel compressor wheel with the standard size turbine wheel on the hybrid, effectively giving the pressure side of the turbo more leverage to slow the turbine down? Unless i'm overthinking it and it just delivers more air meaning more maximum pressure within the limits of the engine.Quote:

Point, I'm probably thinking about it a bit backwards, as I was thinking of it being a smaller turbine wheel on the audi unit than a larger comp wheel on the VXR unit. Probably why my previous posts only sort of make sense lolQuote:
