hi guys

I need to know which turbos would make a high power on pump and race gas ? 6466 or 6766 ? the engine is 4G64 2.1L .

the turbo kit is twin scroll T4 MAP turbo kit

thanks

 

Both turbochargers are going to make high power on pump and race gas. What are your goals with this setup?

 

850whp on 40-45psi .. my setup is : MAP satge2 4G64 2.1L o-ring , AMS CNC head , MAP twin scroll T4 turbo kit ( 6466 or 6766 ) twin DW300s in tank , 2150cc , and alot ..

 

There hasn't been much testing that I know of with the 6466 but it does look promising. I would wait a couple of weeks to see what is released from PTE as far as who tested it and there results.

yah that why I'm still waiting , but I think the 6766 is the best for really high power .

 

Both turbos maxed out the 6766 will make more. The 6466 will be close but will not make the peak number the 6766 will but will have a better power curve

 

Both turbo's are rated for the same horsepower. I have seen 50psi on both turbo's make 950whp.

 

Wow. What is the most you have seen out of a 6266. I cant believe 6266 to 6466 people are seeing 200HP. I would think more like 100whp for the change but I have yet to see a 850whp 6266 graph.

 

Nobody said there was a 850whp 6266 graph?

 

PTE says a 6266 was 735 and the 6466 is 900.

Correct, however @50psi the 6466 has made 950whp+

 

maybe i am confused. you said the 6266 and 6466 are rated the same. or did you mean the 6766/6466

to many dam 6's in this thread.

 

he said 6466 and 6766 but in your defense, yes, alot of 6's

 

You misnterpreted what I was getting at. Sorry I should have been more clear.

If the 6466 has made a witnessed 950whp on a dynojet I would think the difference between the 6266 and 6466 would only be 100hp at best for the mechanical difference bewteen the two turbos.

I have yet to see a 850whp 6266 graph. Have you? If there is a 6466 graph at 950whp dyno jet it makes me optimistic that a 6266 could crank out 850whp dynojet on kill in a well equipped set up.

 

Ok then I am sorry. thanks for clearing that up
