can make more power with the 467.7 seems to be the main swap people are doing
466, 467.7, 468- for what your wanting. They are all the same really.I have ran a s472 on my 08 and it did great with just efi and stock fueling. My question, would a 466 be to small with a 2nd gen swap for a 12 6.7 with mcc and 100hp inj. Towing and etc? Some threads say they wouldn't go below 467.7.
Don't always follow the norm. The 467.7 is the new "TURBO". But I have yet to see any comparison showing real hard data putting it out ahead of any other turbo. I'll keep waiting.can make more power with the 467.7 seems to be the main swap people are doing
Absolutely nothing wrong with the FMW series of turbos. Also absolutely nothing wrong with a standard 466. Both will work just fine in your instance.I Can get a great deal on the s466 just don't know if it be enough. The mcc and 100 hp injectors all I'll go till I get the s480 beside the 66.
Don't get me wrong. I have no issue with the 67.7 fmw. But for what 99.9999% of the guys out there need. (Which is well below 700 hp. not alone 800hp). They will never see the top end of even a 366.There is data available showing the difference in the 465, 466 and 467.7 fmw. There are also several dyno comparisons out there. The 467.7 will support power similar to a 472(actually more than the old 472). We have customers in the 800s on the 67.7. Its been taken farther than I ever though it could go. A 72 has a hard time reaching the 800hp mark. So yes, there is a huge difference between the 65/66mm and the 67.7 fmw. Price isn't very different either.
I went from a 366 to a 466 and there is a difference. With the same mods in my signature for my Mega cab; the only thing I changed was the turbo/manifold. I had to change the tuning. I was running a smarty with the 366 and it ran perfect, zero lag and spooled as fast as the vgt.Sorry Bignastydodge, but since we have the heavy hitters on here I need to ask this.
After winter passes and I pull my car seat hauling truck out if storage, I am going to run a 2nd gen swap. I am hung up on the 366 vs 467 too. I don't want to race, sled pull or pull any trailer for that matter. I'm probably going to put a 85 over pump on with 100-125's.
I've seen a post were a 366 owner went to a 467 and hated it. I don't want a laggy turbo, that's losses my bottom end torque. I just want something to fart around town in, that's going to break the tires easily.
I'm no turbo expert, but it's hard to see where a 366 isn't what most guys should run. There's no lag, little bark, no need for a BOV and very few of us need a 800 hp turbo, that lights at a higher RPM then the smaller turbo.
Where am I going wrong? Also, I'm defiantly going with Dave for the tunes and most likely Blacks for the swap, so I'm not looking for a big dog war.
I'm not a fan of the 366 at all on a 6.7. But at the same time to say its at its limit with no fuel or anything is completely false...A 366 is at its limit on a stock 6.7 without even a tune.
Im very familiar with the limits of the 366. We were the first to take one over 700hp several years ago on a 5.9. They are great turbos, especially the silver bullet line. I have installed several on 6.7s with basic deletes and tunes and almost every customer complains of high egts with the s300. Moving to the s400 should only change spool time by a couple hundred rpms. And the s400 is gonna keep egts much cooler. And the best part, the s400 is a beefier turbo, so your getting a stronger unit for a little more money.I'm not a fan of the 366 at all on a 6.7.

I've tuned them all the way up into the 700's before..
Here's a chart from 2 weeks ago. 75hp tips and a 366... Looks like a pretty good matchup to me for 600hp.
Its all in the tuning and leaving anything to stock tuning is throwing money out the window...
