Trying to decide which turbo i want to run. I here numerous things of both and im having a hard time choosing. Im shooting for 650whp for now and 800whp max after the clutch goes. The car will see the street on occasions but 95% of its life will be on the track. Id like to break 9's possibly make it into the mid 9's at some point. Here's my setup. The setup is in a 2300lb 98 civic ex.

I guess the real question is what are you looking to spend? Is your manifold a dual scroll type?

 

open housing - 6765
twin scroll manifold - 366

id opt for the 6765 in any case...
that or i would hold off, and see what BEP has in store for the 66-67mm guys looking to get billet wheels..

 

i can get the s366 for 950shipped and 6765 for 1040...but to answer your question money is not of a concern. I have a open flange its not twin scroll i wish!

 

PTE 6765 all day....

 

ive been loving my 6765,highly recommend it

 

goign with the t4 6765 with the sp compressor cover and .96 v band hotside

 

How much difference between the dbb 6765 vs the journal

 

there like 1400 and supposely spool about 700rpms sooner

 

Precision can repair if something goes wrong.............+ 1 For Precision!

 

well you have it there... everyone recommended the pt6765! you can easily go 9s with it... 366 isnt a bad choice also

 

im thinking the same weather to get the BW s300 91/79 or the precision billet 6765 journal...

both looks/performs promising...

can we get some dyno figures?

 

The 6765 will support more then 850whp. the s366 will not.

 

You can get the Precision Billett stuff with divided housings just not from precision, so this should not be a determining factor.... I am selling my 67ho for one of the 2 Turbo's mentioned I am just not sure yet, if the 6765 is more responsive than the S366 in divided form I am sold.

 

what kind of gas are you gonna run?

 

^^^ that was going to be my question...

I have ran both turbo recently. I'm running on e85.. so the limiting factor was my fuel setup.

On the s366, I maxed my injectors (1600cc) out around 713hp.. midrange on the s366 compared to the 6765 is a lot higher. I would say 75-100 hp.
Right now I have the 6765 billet non ball bearing turbo. With ID2000 and at 32 psi I made 797HP/504TQ on e85 with room to go, but my Intercooler piping was having none of that. LOL

I will get a graph comparing the two setups. But with experience the s366 comes in earlier. The 6765 comes in a lil later but it comes in HARD!

 

at what psi did you make 713hp with the S366? In for that graph

 

im gonna use c16

 

38psi according to the sig. I'd love to see the graph as well

Whats up man, glad to see your build progressing well

 

Hey greg thanks bud! Im done with it once i get my turbo in, MikeFLturbo is hooking me up with my 6765. Sometime this summer im gonna get rid of the lovefab manny and have you build me a topmount and upgraded to your catchcan setup. My i/c setup you built is flawless and i cant wait to get more of your products for my vehicle.

and 38lbs for 700whp **** that i wanna be at 800 or a little over around 38lbs

 

Please post graphs of the two.

also which of the two turbos did spool sooner and has a fatter power band?

lastly, what are the specs of the two?

 

Here's a dyno of the S366.
1600cc max out

The 713HP was done at 38psi, but it went pretty lean so we had to back that down. The blue graph was a retune by Alex at Humble Performance. The goal there was to make more mid range power. As you can tell there was definately more power in the mid range. We added more fuel and a lil bit of timing and brought the psi down to about 32psi, but the power topped out at 666hp.



I haven't received the graph from Alex with the 6765, but as soon as I get that I'll post that one too. But here are the numbers I wrote down after each pull
14 psi = 494hp/311tq
20 psi = 561hp/343tq
25 psi = 706hp/444tq at 72% duty cycle
28 psi = 762hp/482tq at 76% duty cycle
31.5 psi = 797hp/501tq at 83% duty cycle

We compared the s366 vs the 6765. And the s366 came in a lot earlier, but tapped out due to the lack of fuel. With some more fuel, I'm sure we could have made more. The 6765 hands down makes crazy power as you can see. The 6765 comes in later than the s366, but when it comes in, it comes in really hard. Almost too hard for the street. I'm actually nervous to make any kind of runs with this turbo. Hope this help you guys out.

 

very nice im assuming you running t4...what ARs for both?

you made much more power with the 6765 at lower boost compared to the 713@38psi on the 366...

 

Peak numbers aren't everything.

 

yes i know

that why im asking who made a more fatter powerband...

hope he post the 6765 dyno graph...
