Hp48 work good on an ej22? Its a na motor, that I just plan on running a fmu on , when I get around to it eventually. Because 130hp won't be enough in the Ghia...

For low boost on a smaller engine like that, should be a pretty good fit. Gotta say I love all the awesome projects these are going on!

BTT

I bought one of these HP48s a couple years back and it's just sitting on a shelf. Never been used. Anyone want one for $175 shipped? Trying to drum up some spare cash for an upcoming track day cause taxes are due but I still wanna party. Help me, help you.

Bumping this to the top again in case Whiskey Business is still around, and to maybe get some others's input. I had bought the two used hp65's way back when, and am finally getting to using one on a challenge build. 

My best calculations for realistic max target HP/RPM (2.5L) put me in the 2.15 pressure range, and ~.30 Kg/S. That puts me out of both the 60% efficiency island, and past the 160k rpm's line.  Looking at the trends of the curves on the map, I think we could assume that would put the compressor speed at ~170k rpms at that point. With a 60.5mm comp wheel diameter, that would be ~540 m/s at the tips.  Is that safe to plan for as a max? 

Here's the comp map:

Definitely still around! Without having to pull a bunch of spark timing to prevent knock, that 0.3 kg/s (40 lb/min) range should land you in the 400hp range. That is definitely further than I think these turbos will like to be pushed. No guarantees on how long they would last at that power level, or if they will even flow enough on the turbine side to support that.

As a side note, I have some of these turbos left as well as some larger stuff that I bought for other projects. 

bluej, if you are still shooting for that much power I might be able to help you out.

Yeah, that's one of the things I liked, that these are sized for faster response. I'm trying to figure out what a max practical limit is, knowing I'll end up at the end of the turbo and cam happy place . Redline is going to be at, or not much past 6k. Do you have ANY other info about these you'd be able to send me?  Thanks!

Still have a number of HP48 and HP65s. Theyre in the garage, I'll check numbers if anyone is interested.

Also have the following generic China turbos, one of each. I'd like to keep these challenge friendly priced, so let me know what works if anyone is interested:

"GT"2876 Internal Wastegate

"GT"3076 Internal Wastegate

"GT"3582 Non-gated

"GT"45 Non-gated

"GT"4092 Big daddy non-gated diesel turbo

 

I think I'd like to keep the 3582 for my Sonoma project, but all are able to go.

Sorry for the slow response, turbos are stored under my desk at work. 

 

BlueJ, I'll respond with specs as soon as I verify them on the turbo.

 

Everyone else, I'll post more info tomorrow.

I need to brush up on my turbo knowledge. Know if either of the T04 flanges will play well with a Ford 300 Inline 6?

I guess I could redesign the adapter for a T3 flange.  I haven't poured it yet so I might as well of that works better.

In reply to whiskey_business :

Would the "GT"3076 Internal Wastegate turbo be a good fit for GM 3500 V6 (220hp variant) limited to 6500rpm?

The car will be relatively light (sub 2300).

How much for the 4092 for a hopeful challenge build?  Can pick up or make Angry come get it and store it.

In reply to Strike_Zero :

It's honestly a pretty good match for the 350-450hp range. . . That would be a rocketship with a light weight car.

In reply to Patrick:

I'm thinking in the ~$225 range for all of these things, will work with people if they can make a case for fitting it into the budget or onto something especially cool.

Is the v-band adapter the only difference between the 2876 and 3076? The specs look the same.
