DAW turbos questions

[Mayday]

I have 2023 MT and my goal to is 500+ whp with 91 octane (95 RON). I'm planning to get DAW turbo but I'm in between those options, DAW 6466 / DAW 6769 / DAW ULTRA FLOW-X ( 6 PORT ).
My current mods:
Catless downpipe
Full exhaust
Cold air intake filter
Charge pipe
Bootmod3
91 octane
intake manifold (soon), thinking to get project gamma

which DAW turbo I should go with? ULTRA FLOW-X ( 6 PORT ) or 6466 or 6769?

i know that DAW ultra flow-x spools instant compared to 6466 and 6769
let say I went with 6769, does that mean I can squeeze more power and get more WHP than 6466 & ULTRA FLOW-X with my current mods?

I know that 6769 is laggier than the others but, larger turbo benefit is making boost with less exhaust pressure. So, less heat being build with boost I’m making. So, giving up spool time for less heating maybe?

and how many WHP I would gain with replacing OEM turbo with DAW turbos + 91 octane with my current mods?

I’m not thinking of port injections , Meth kits, E blend or methanol
ONLY 91 octane

I read all the thread here, but I can’t find an answer for what I’m planning to do.

following, also had the same question and came across your post while researching

Bump this thread as I also had the same question.

It’s better to have power across a larger rpm range than going for peak power especially for the street. Don’t get so hung up over peak hp numbers.

A larger turbo will make more power on the same boost level or make the same power at a lower boost level like you stated but at the cost of slower spool.

I think for 91 octane the 6769 might be a little too big. (I’m running a 68mm turbo on 94octane and feels like it’s big). Perhaps the 6466 would be a great balance between spool and power for the street on 91 octane.

We have the project gamma intake manifold available by the way if you are looking to order:

You can always counter boost lag by brake boosting and should never be hitting boost under 3k rpms.

thanks for your reply,
let’s say if we are comparing spool time and power between these two
DAW 6466 & DAW Ultra Flow-X
is the spool response are similar?
how many psi I can push with Ultra Flow-X before the turbo blowing a hot air?
as you know, the OEM is blowing a hot air at the maximum boost which is 23.2 psi in OTS map.

so speaking on project gamma intake manifold, I’m really interested in this. but, any results on that manifold?
I’m planning to get an Intake Manifold and DAW turbo at the same time. I would be appreciative if you could give me some feedback about project gamma intake manifold.

at the end, my car is daily and i will track it soon so my goal is 500 whp, safety psi with 91 octane.

DAW claims on their website the Ultra Flow X will make 730+whp and the 6466 800+whp. Of course those numbers are on ethanol but it will tell you that the 6466 is a larger turbo with more power potential and slower spool time.

From what I have seen the Ultra Flow X made 524whp on 93 octane at 24psi. On 91 octane you would probably make just under 500whp, but it also depends on the conditions and the quality or your 91 octane fuel. I haven’t seen anyone dyno a 6466 on pump gas yet, but it should make slightly more power and I’m guessing the spool should be around 500rpm slower.

To be honest either the Ultra Flow X or 6466 should be a good choice for you, but I would not go with a 6769.

As for the project gamma manifold I haven’t seen any 3rd party testing yet.

If the 500 range is your current power goal, on 91-93 octane, then I would suggest the X. The 64 is a great turbo, one of the most popular that people have ran for many years on MKIV's. The spool I would think would be around 500rpm slower as compared to the X. The 64 would provide more mid to top end, but if you want room to grow with adding meth, PI, LPFP, etc., then I wouldn't even consider the X, AND your power goals are above the 700 wheel mark. The 64 or 67 would be a better option. As everyone has stated the larger the turbo, the slower to spool, but the tuner can always add antilag on the tune for you.

I personally have the X, and I can vouch the way it spools and the way it responds with E. I love the quick spool of my X as compared to the stock. It pulls all the way to redline and can easily push the stock tranny to its limits, if you have the other supporting mods. The choice is yours honestly.

I only wanted to comment on my personal experience with the X. I love it and everyone who runs it, does also.

You can't compare a DAW oem frame style design to a full frame 64 EWG turbo.

Just the back pressure differences alone...
