turbochargers for 500hp

[bartolomeus]

I didn't put the car on the dyno but I was told by PRJ it can do 430 HP.
But this turbo won't be boosting hard by 3000 RPM.
Here is a video with the car accelerating, but it's was with the first map which wasn't the best, this is my first flat out of the car after the 1000km break-in period

Ok thanks. What sort of power can you achieve. I only throw the holset into the mix as you can get a brand new one for about half the cost of the other options. I would prefer a turbo that will be boosting hard by 3000 rpm ish and supply 500bhp approx.

Cheers

Nick I had Holset Hx35 but it can't do 500 hp. Maybe HX35 Super will reach that figure.
It built spool at 4000 RPM and it was a bit laggy imho.

Was looking at gtx3076r. But also thought about holset hx35?

Also been offered used gt3582r and gt3082r

thoughts on all these turbos. Looking for around the 500bhp mark on an aan engine with rods.

Thanks
