Soooo what how does the HFSB compare? That's what im running

Good question, but no one will ever know unless somebody takes a turbo apart and starts measuring wheel sizes and such.
Pius at bell keeps his turbos top secret, just goes by hp ratings.

The hf has a bigger hp rating then the ba so could be a bigger a/r on the exaust or bigger turbine or bigger compressor. Who knows. Trying to get actual specs is like winning the lottery.
My guess it's probley a 66mm variant of the ba.

My 364.5 fmw I ordered thru works turbochargers.
It started out a box 362 fmw, they machined the comp housing and put the 64.5 wheel in it.
It's got the 68mm turbine with the 1.00 a/r housing.

I'm having same results as most on this forum who are running the basb from bell.
It spools fast and I can lug the truck on a hard pull down to 1500 rpm and still stay under 1200 egts. Couldn't do that before with my s366.
I can cruise pulling 10,000 lbs nicely at 10 psi boost 1800 rpm with egts around 1000.
My 366 would be at 1200 almost all the time.

Overall it cost me about the same as a bell turbo but I got it built in a week.

Very old thread, but curious as to how everyone's setups are doing. Mism my ole 96
Doing fine....use the OBS for light towing and day trips. Use the dually for the heavy towing from a safety stand point but the OBS does come out of retirement if need be 💪.
