My observations and opinions of current street/strip turbo LS trends.

Sometimes its not all about all out power and drag racing. I chose a PT76 for the quicker spool for road course and auto x events. A big BW would have added more weight to the front of the car and spooled slower even with the same size compressor and turbine wheels.

well that i know that. i shouldve quoted the post about the twin turbo setup with GN turbos. clarifying my question is, are there turbine and compressor wheels out there that can be put in those smaller housings but flow a little more and still have the same insane spool? i mean the GN turbos are 80's tech and turbo compressor/turbine wheels have come quite a long way or is it the housing itself that becomes the issue more than the hunk of spinning metal no matter the design?

Anyone seen the batmo wheels offered in the Bullseye Power line of turbo's?
If you take a look at Honeywell's website the design is directly related to their jet turbines they use. Trickle down effect in regards to technology.
Intimd8 would be a better person to ask about the different designs on the smaller turbine stuff as I have no where near the amount of knowledge he does on those applications.
I am a single turbo kinda guy, but really enjoy a well matched set of twins when the budget allows, which the majority seem to be able to afford a single set-up easier.

Yes there are better designed wheels out there for sure now.

the fact that the blade tech is progressing to a point that they are miniaturizing (basically) Turbofan jet engine blades is a phenomenal (and seemingly obvious) thing. i believe phil is using something similar on his renegade car.
if one could just get those turbines to flow more without sacrificing much spool, if any, would be killer on that gn twin setup.

im sure he'll weigh in when he posts again.

Axel flow turbines should offer a significant drop in wheel weight as there is no need for the backing plate part of the wheel. The turbines will run at higher rpm and thus the use of smaller twin sided compressor wheels. Should mean higher efficiencies as the speeds are higher.

Right, and no disrespect intended. Im referring to the fact that a lot of people are misguided and the little info that would steer them on the right path isnt going to hurt you at all....that is what was talked about in the original post.. right? The recipes you guys use for your faster and custom cars by all means I wouldnt and no one should expect you to just dish that info out. Im just saying if you are on here all the time, you obviously has some time to spare. And helping out the smaller guy only makes you look good.
I was more referring to Reckless and his post about not giving out tech here.. on a tech site. He stated that
But he has time to be a moderator? This makes perfect sense.

It's like the little retailing I've done with wheels as I'm a Weld and Billet Specialties dealer. I'm happy to give folks some thoughts, but asking me what part number to order and then not ordering it from me even though I shot a competitive price is no good.
Shops make money on parts, and labor (building stuff) as we all know. Asking for part numbers on fitments is very appropriate on boards, but when you get into stuff like setting up the shortblock, etc., specing the whole combo shops will go broke being a tech hotline.
I was hanging out with Kurt at Milan this weekend and we were talking about converters and he was happy to chat for a bit. But if someone came up and said what longblock setup would you run, he'd say great let's chat and get something going.

Keep you eye on the exotic market and when they arrive add another 5years before you see them in the aftermarket scene! Its a bit like vnt. It's going to be a while before you can buy a turbo off the shelf with this tech.
