turbochargers for 500hp

[Jaswan]

gearbox, clutch, drive shafts ect.

X2

plus rods and crank shaft.

If you have 600Nm from 4000 to 7500 rpm it is good enouth. You have to use gerbox some times

500Nm at 7500 gives over 500HP

[S2central.net]

Agreed... something like 600-650Nm from 2500-7500 would be amazing, but probably bends some laws of physics to achieve that !

What sort of problems other than clutch slip. I want over 500 ft lb....

My opinion is that the car should have flat torque line. Some cars are tuned that they have diesel line with neck braking power first and "nothing" at the end of the revs.

a responsive turbo is a good think, but too much boost/torque low down will break something.

yes ! over 600Nm problems start, specially on low revs

You get what you pay for

You kann get a Holset for 700€ from Turbozentrum-Berlin

This EFR 7163 has a 57/71mm compressor and turbine with a large diameter of 63 or 64. Cant find the small diameter though. This turbo is HX35 range. Not super not fancy hybrid.

Appart from the above not only KKD sell Holsets. I never bought a Holset for 800 Euros. There are also other sellers....

Nice price! And you get same result as with an tractor turbo. [emoji481]

The HX35S is 800 euros and add the shipping cost that's going to be around 900 euros.

Buying a garrett is in the region of 1500-1600 euros and as they are more readily available you can pick them up on most turbo shops.

The efr I don't know. But if you were to order it from the USA then I'd expect 2000$ or 1550euros with shipping included.

So the price difference is there but it's not 350euros for a holset as it's been repeatedly mentioned on several occasions.

Full boost (20psi) at 3500 rpm with EFR 7163 with 0.85AR turbine housing on 2.5 lt Subaru engine.

Those borg warner seem to spool up very well ans give good torque. But they do come with internal wg and dump valve built in. Can these be removed easily enough to run ext wg etc.

diesel-des has a variant of the EFR6758 that runs external WG and DV... dunno how much of the external WG is off the shelf option vs 'desmods'
