I just saw the dyno graphs of yesterday!! The 6466 turbo is unreal. It spools SO much quicker. With the stage 2.5 in pump gas mode it hits FULL BOOST (15psi) at 4,200rpm!! The top end also kicks the older 6776S's butt in pump gas mode. We will have the methanol maps and race fuel maps done shortly. As long as it can flow the air at the higher boost levels the 6466 will be an amazing turbo to have with our kits.

I will have comparison dyno graphs and videos early next week

I need to see what this thing does at 18psi pump...and 23psi with meth For a direct comparison of course

needs new fuel pumps apparently. FICs are in but they thought the inline failed. after replacing it the car was still too lean up top. intank is next on monday...hopefully then they can bring the boost up to 18/19 on pump

I wonder if the turbo will show any more appreciable gains(over 23psi) at 30psi. I dont know if this car wants to be the guinea pig for that experiment...or if it will be able to flow enough fuel at that level either.

I'd like to see if it runs out of steam or not at 30psi.

Why would u arbitrarily push a 64mm to 30psi?
John is going to push it til it starts to fall off and that's it... Whatever psi that ends up being on each map.
What I'm eagerly waiting for is one of u 71mm guys to step up to a qsv setup!!!

Need a new divided turbo for that I thought...

30 psi is not an arbritary number. It does seem to be the max boost that many shops choose not to exceed.

But you are absolutely correct in pointing out correct procedural issues. One must be careful around here. LOL. You will be brought to task for not posting correct procedures. I am Guilty as charged for omitting procedure.

Boost should always be increased slowly and in steps.....taking time to analyze data from each pull. NOT, just choose a max psi number and run with that.

The gradual way will indicate when more boost is not giving any more increases in power. You should be able to see the drop off when ever that happens.

What i should have said. "I wonder at what psi the turbo will run out of steam. I wonder if it will continue to make power all the way to 30psi which most shops dont exceed."


I know HPF likes to use 23psi as a max setting, but they will exceed that depending on a number of reasons including a discussion with the owner.

I remember Jason running some higher(than 23psi) max boost settings up to 30psi. I dont recall many builds that ran higher than 30. I am sure there were a few. Some/many (not sure) shops use 30psi as a cap. That is also the cap on my build. Thats not saying we will automatically run 30psi.

I am not sure what's so special about 30psi, or what can happen beyond that figure. I notice it being used as a max setting more than a few times. Maybe knock starts to be an issue. Perhaps head gasket issues can arise..or 30psi is a spot where diminishing returns take over. It just seems to be figure that many dont wish to exceed.

Who cares how much boost you are running if you have the proper fuel and engine internals to handle it? Why stop at 30 if the turbo will make more HP at 40? Why stop at 40 if it will make more at 50? On pure E85 I have no limit to the boost level as long as the turbo is making more HP. The problem I see with the M3 motor however is that above 900 RWHP there is some sort of bottle neck which we are initially assuming is the steedspeed manifold. If that was not there I would certainly run Tom's car above 40 psi with his 7675. If HPF is stopping at 23 there has to be a reason such as octane.

It's situations like this where I like to say...

TOM FOR THE LOVE OF ALL BOOSTAHOLICS...LET THE MAN BUILD YOU A MANIFOLD!!!

Fly down for a visit...scare yourself shitless and return wanting more

I have been talking to Larry recently about this and that. A HECK of a nice guy, BTW!.
Well, He certainly opened my eyes about boost. I want to learn more. We take it for granted but many of us dont really understand it as good as we think we do.
I hope you (Larry) might take this discussion even further. I started a Boost Basics thread. Everyone is invited to post.



Whoops, sorry. That's my man scaping channel!

A tubular manifold will be next I have been told. It should make a redunkulous difference. Tom's car will likely shatter all records. And yeah, it'll be REAL scary, Freddy Kruger eating someone's liver scary!

I heard Tom was getting a sign made up for his car's interior. "Warning! Cork and tape all unsealed human orifices in order to retain internal organs.(and feces.)"

Agreed. I'm chill just boosting smaller turbos into the mid 20s ....
4k powerband w/a sensitive throttle ftw
