Well no ------- ---- shirlock. And yes "Super 60" is actual patent by Turbonetics, obviously they buy all their wheels from honeywhell but they do cast all of their housings. My point was that the "Super60" that is listed on cheapturbo is not really a Turbonetics super60 with a 64trim and 1.900 wheel. When I first saw that turbo on Cheapturbo/PT I called them and asked them about it, because I wasnt to sure what it was, and that is what they told me. It's "garrett's version of a super60" which is just basically a .60 trim. Also, how does cheapturbo put a .42a/r housing on a 60 trim? because I just tried putting my saab housing over my tbird's 60 trim wheel and it hits

Anyways, trying to stay on topic, What is going to be an advantage of putting a 45 trim or 50 trim in a .60a/r .60 trim compressor housing. Since the housing is going to have more surface area and the wheel wasnt even designed for it, will it even be efficient all?

I had a true 48/60 on my d16 crx, and when I put this housing on the 42/48 on project cheap **** integra it pulled way harder than a standard 42/48 would.

Darksol did this housing swap on his B16 del sol and I thought it felt like a 42/48 D series, but on my integra it felt as you would expect with a 48/60.

There was no more turbo lag than you would expect from a 48/60 from what I could tell either.

Any change in larger A/R is going to hook the compressor map slightly to the right but the surge lines as well as choke lines will still be same as will the max Pr. This is potential for gain and not necessarily a gain in itself, unless you use a butt-dyno like Stealth.

Thats funny, because I am the master of the ***-dyno so I would be able to tell very quick. :P

Not much especially at low boost. The reason you'll think it's a gain is because of the motor it's installed on and the butt-dyno that measures it as being "way better" or pulling "way harder". In order to figure out what the wheel is potentially doing, you need to calculate your VE at various rpm along with the boost you're running and use those figures to put you on the compressor map (which is still theory and isn't absolute)

The reason a larger wheel is put into a small A/R housing is to minimize lag, even though the compressor wheel is still the lightest part of the rotating assembly.

It won't be much different than the standard wheel int he standard housing except the map will be shifted slightly to the right. The speed lines will still be the same as will the choke and surge lines.



With a bench lathe. You guys on HMT refer to them as a Dremel

I just find that hard to beleive that they would machine all those .42 compressor housings to slap them on 60 trim turbos just for lag reasons. Thats retarded, if I was buying a garrett super60 I wouldnt want no homo ------- 42a/r housing on it.



Oh and Sixsick6, we appricate all your turbo expertise in this thread, you get 2 ***** up

^^^ buhaha .......now this thread needs a NSFW

As do I. How much would you like to bet that if 99.99% of people took the time to actually find out for sure what they had purchased, you'd no doubt find alot of 45 trim wheels in .42 A/R housings rather than 60 or "Super60" wheels. A majority of these companies, especially the ones dealing in bulk aren't taking the time nor the effort to do things properly. They're counting on their customers ignorance. A majority of these online companies are out to make a buck on an unsuspecting 16 year old who would be none the wiser.

That being said, if you happen to have a .42 A/R housing which claims to have a 60 trim, "Super60" or even a TO4B or TO4E wheel, you'd be a fool not to open it up and at least check.

Fair enough?

Nothing to say now?
