It makes little sense to contend with a shorter powerband and slower spool, unless a larger turbo is made to do something the smaller turbo positively cannot do. Unless the larger turbo is generating significantly greater power, it is at a disadvantage when the rubber hits the road.

The HTA3586 has powered amazingly quick and fast track times, not because it's the largest turbo or delivers the greatest peak power on dyno sheets.

FYI

I've noticed that 6765 indeed makes more peak power but the power band from the 3586 is very good , hitting full boost at 4.8k is really an advantage on the other hard, the 3586 seems to die up top?

Are 157mph trap speeds indicative of something that 'dies up top'?

Hmmm.

it depends what you call UP TOP.. Over 9k Sure.. You need more compressor to keep up really at 8500+..

I personally think the hta3586 is one of the best turbos out there, the fact that you have to run 44 psi to reach 800's is too much boost it's like maxing out the turbo

40-45psi on a 3586 is not ideal is more like pushing it to it's limits IMO, 6765 or HTA3794 can make 800 runing 40 psi and that's keeping the turbo happy and leaving some room for more boost.

So are you implying that 800+whp and 9000+rpm keeps the engine 'happy'?

You are expressing concern about pushing a turbo, when at the same time you're talking about pushing the limits of an engine that costs several times as much as a turbo, and is at least as likely to suffer a failure under those conditions.

A larger turbo doesn't necessarily make the car go faster (not without more rpm potential anyway), isn't any 'safer', but does spool slower. I'm pointing this out for your benefit, not mine.

That's all I have to offer on this topic.

Id have to agree with TED on this one...

Boost is 10x easier on an engine than RPM.. Id rather run 60psi at 8k RPM than 40psi @ 9500.. Youll need to rev your car to use the 6765 and hta3794..

HTA86 still til this day is what 99.9% of anyone on here can use for t3 turbos.. I am yet to see anyone run anything close to what a 6765 can run.. which is 8.75 ..

Oh and 1 other thing.. Dont be SHOCKED to see the car struggle to break 800hp @ 40-45psi on 6765.. if the combination is not right i have watched cars struggle with 6765 to touch 800.. Dont go off the 900+ you see from our cars dyno sheets..

I wonder if I should put my car back on the dyno to break 800 at 38psi on a cooler day?
