Hey everyone, I have a 2013 LML and am at the point with it where its time to look at turbos to take it any further. I have bugged Jason Wehrli likely to the point of insanity about different options but am curious to hear from some guys on the tuning side. I am looking to have a fun street truck in the 600-650 hp range. I am looking for something with crazy low end response and smokeless ( I know they will all smoke a little at WOT until the turbo catches up) since this is my daily. I know a Twin or VGT set up are likely the best options, and Mark has some stuff coming out for the LMLs now. But I don't really want the added complexity and potential issues of a twin set up and I really hate the way VGT chargers sound. So I have been looking at either the S364.5sxe or S366sxe chargers with a pretty tight .83 AR T4 divided turbine housing. My question is, is it realistic that either of these turbos could be tuned reasonably smokeless while still retaining great low end response and being fun on the street? Any insight anyone has will be greatly appreciated!
Can a Fixed Single be Fun and Clean on the street?

fast spool on the lml with 650hp worth of air. Can be tuned clean easily and you have the durability of a s400, not a small s300 being pushed in it's power capability range.

Yup, I had been running a 468 single and I just picked up a 463 from a member on here a little while ago to try out and so far I've been really impressed with how it spools.. I switched tuning also and it's not near as smokey as before (still trying to work out a couple little kinks with my cp3 pressure though)..
But like you know, it won't spool like a compound setup with a stock turbo will of course..

There's no complexity or issues with twins. From what you described you're looking for its actually the way you should go or with a bigger VGT. Like everyone has already said...what you're asking for really isn't feasible. You're going to loose the bottom end and the bigger the turbo the slower the spool and lag. On top of it you want no smoke so its going to be even worse. Smokeless tune and good low end response don't go hand-in-hand unless you're shooting some nitrous. Plenty of big singles out there that will spool fairly quick and be "fun on the street" but smokeless and good low end response they will not have. If you're dead set on a single the S369SX-E is another good one to consider but with what you're wanting a VGT is your best option.

Im.pulling off the s369sxe and fitting marks 68mm stg2r on my built engine setup in my sig. For what i do the s369 is no good to sluggish down low and towing
This would be a good option but he don't sell them for the lml, unless that's changed recently..
Thank you all. Like I said, I know VGT or twins are likely the best option for me, I just prefer the sound of a fixed charger. I see guys all the time on here that talk about how their s472 "spools just like stock" and are basically smokeless. I kind of figured it was mostly BS but was wondering if I was missing something and could have my cake and eat it too so to speak. I am currently planning on built trans w/ goerend R and getting the truck live tuned in the spring. Then I will go from there on figuring out if I really need more. Realistically, I just want a fun DD street truck and don't really care about top end numbers, the 600-650 hp goal would be just for bragging rights, so maybe I can get what I want out of the stock charger and just forget about bragging rights and dyno racing.
Kiwi, talk to Mark if you want to go back to VGT, he has some options for the LML now.

The single s472 i ran for a long time was a blast. Even with stock injectors and a stock cp3. Plus, large singles may save your bottom end compared to equal power from a compound setup.
Im running a s468/83 1.0 a/r with a cast wheel from Danville with stock fuel on my LMM. On my lower tunes it still spools great and does not smoke much. Mine is tuned by PPEI, with good tuning/trans tuning I wouldnt hesitate to go with a smaller fixed vein on your LML.
I hear you sounds good but I don't reckon I'll go back anymore.. If I do anything more it'll be bigger injectors and adding a 480 or something like that..
But I will say if I was to do it over again right now with the more options available, I'd go with a bigger vgt.. I think anyway lol.. I do love the sound of the single fixed vane.
