Looking forward to trying out the LBB!
Going on a 4.8L GM engine in a retro-fit. Currently have a HE451VE slated to go on it, but also just picked up an HE561VE as well (should be a 71/102 compressor 86/80 turbine wheel).

Thanks! I'm looking forward to it. This motor is a turd N/A. I know the big one should be close to an S471, so it should be a little work for my little 4.8L to spool (if it wasn't VGT). It comes off of the big cummins ISX.

Not gonna lie I want that 561. 

I Need a reason to step up to a triple disc converter

Yeah i found it a couple of days ago (cheeeaaaap). Really anything smaller is futile on a gas V8.

My gasser already has a triple disk and it flashes to 2800 on motor (I've got a built 4L80E). I bet I can make it surge with the converter locked up  8)

I guess I'll be the guinea pig on the 561s for the lilbb. I haven't heard of anyone using it with stock cummins computers with them, I've only seen people use the 551 which has the air cylinder stock.

sweet another gasser. And big vgt. Man I looked for a HE451ve for a long. Is it the 64mm 93mm compressor?

65fpvmustang

mine has the 86 80 turbine but 73.6mm inducer and 105.8mm exducer. Off a volvo is all I know got her for $200 shipped. but no actuator. In the middle making a He351ve actuator fit my he5??ve.

I don't have the 561 in my hands yet (in the mail), so I haven't measured the wheels.

Yeah the 451 is a 64/93 compressor and 76/67 turbine.

i wanted the he451 for my 289

I have been keeping my eye open for one for awhile, I think my wife might kill me.....but it would be worth it

I think the 561 would be something else in my old Rx7... might take a little while to spool it even with the vgt, but it would be something freaky when it hit

13b will spool it they spool the hx60 around 5500
but you could always do a compound set up. Vgt widens our power band alot.
the compressor is limiting factor now.
