The 75mm compressor wheel isn't being driven by a stock turbine wheel
Never said it was..
Is there a reason to make a 66, 71 or 75.. maybe.. but the turbine housing isn't designed to have a turbine larger than stock let alone a 73mm exducer turbine that it needs to run a 75mm wheel.
If you are going to run a 75mm compressor, the stock turbine or 71mm isn't going to cut it.. You don't run s475 wheels on less than 73mm exducer turbines do ya? Then why would it be kosher in a hybrid (compromise) turbo like the LB7 offerings?
I am not arguing with you Brayden, lol, I am simply stating that it is being done and its working well and these turbos are going to be very competitive in 2.6 and stock appearing charger classes this year. David's intent is not to offer something that the every day driver would buy here.....his intent with these turbos is to win, that's it. Anyone can ask him, when he told me about them I was like " that's insane, the turbo frame won't handle it." His response was "they are holding up so far and putting down number higher than I even expected, so who cares?"
I am living proof of displaying that what something does on paper and in theory is not always indicative of what it does in reality

This is all some great info guys, but like I said, I'm trying to build my own setup, not purchase this company's charger or that company's compressor wheel. Would love to test something new. Like I said to Tim earlier, already have a wheel design in mind.
Thanks Brayden, that's some great info I was interested in. And Kspen, thanks for the link.

Theoretically, a 96mm turbine in a 1.32 housing shouldn't spool an 80mm compressor wheel faster than an 87mm turbine wheel and a .90 housing....but they are.
Only when Dmitri is standing in front of you with MY nitrous bottle helping you "get it up"
I mean we can go big. Really interested in two options:
1. A drop in wheel design and a port and polish, with a possible upgrade in wastegate for better response
2. Then an all out, bore the crap out of the compressor, port the heck out of the turbine, and stuff a 75 with a 73 like Brayden mentioned

I know right! In every sense that picture should be used in at least one Blue Pill add haha. Thanks again by the way. That NX controller is gone now....
Alex,
We make decisions on what the truck is used for and how it will drive. Our billet 63mm covers 90 percent of the people out there, and at the end of the day it's all about selling turbo's. Can we make a 68,71,75 stock appearing? Yep we were the first back in 07 to do an IHI stock appearing hybrid 4094R 68mm. It worked well, but there wasn't much call for them so we redesigned and used the S300 frame and it's cheaper, stronger and more configurable.
For anything that isn't stock appearing though, we push towards a pedestal turbo because there is no compromise there. It'll make more hp for dollar and give you room to grow.
Hope this helps answer your questions.

Thanks Brayden, some very valuable info. That is why I was leaning more towards a drop in design for the compressor wheel or at least one that doesnt requiring much modification. The blade configuration I am pondering should flow very well and then I will port out the turbine housing. Want to go for a custom, done on my own, type charger. Will have to see if Tim thinks it's something his sponsor shop would be interested in making.
Just bring it out one of these days, they are good friends of mine and live on the other side of town
I think Trent did one also a while back but not on a stock charger and if I remember right there was some good info on why you should not go to big on the porting of it.
On mine I only ported the exhaust inlet to be the exact diameter of the up pipes and polished it out the rest of the way up to the turbine housing and smoothed out the casting in there as well. On the compressor side polished the entire inside and outside of the compressor housing and cover. I can't really give an honest "difference" that it made on my truck since the compressor wheel was so destroyed before, but in comparison to other lb7s I notice a major difference in mine.
Ok guys lots of great info in this thread. I have some questions of my own to add adn hope someone could give me some good thought process.
Since I was on a budget when I built my motor a few months ago, I didnt ugrade my charger setup. I have a batmo in the IHI now (not sure if I ever gained anything) but I'm looking for more air. Before Trent went away, we had many conmversations about upgrading my setup, but due to cost, I never tore my kit off to have him change the pipes around and drop a S366 or 71 in its place. So here's my question.....Would a 'cheetah' or DTS or Danville IHI modded charger work well and get me to over 1000hp? I'd love to hear thoughts on this.
As it stands now, I LOVE how fast the charger lights. Its actually wicked. I don't really want to sacrafice that as its downright fun on the street, so I'm hesitant to put a 366 in the mix and loose some low end spool. How would a modded IHI be? I'd be ahead of the game as I wouldnt need to change anything in my setup excepet pull and send my charger off to be "worked". Anyone feel free to comment. I have no time slips on this setup yet. It going to run it as is, and then I start my quest for more air, and four digit horsepower numbers :cool2:
On Edit: I know I can reach this goal with a simple charger swap...but I DONT WANT TO. I want to be a little different and say I made 1000hp with a stock charger. I like to break things in my spare time so this project is no different
