And is actually balanced. Mark put up a vid showing i think a 4094 out of the box being well off 0, and then after he balanced it. Big difference.
halfway related to the turbo talk. Ready to take off my stock down pipe wondering whats better a wrapped pipe or a coated one? Just straight pipe and KN intake with stainless wheel nothing fancy just my daily driver not going to upgrade much on this truck.
I know you can touch the heat wrap a few minutes after a run, which makes me think that is the way to go. Highly doubt you could touch a coated downpipe for a long long time after a run... My two cents

Do you live in the rustbelt? The wrap makes things rust faster. After only making my few yearly trips up north in the winter my dp has started to have deep pits. So I rewrapped it so the bottom 6" of the dp isn't wrapped.

Yes that is it and remember you get your $300 core charge back when we receive your good core which makes the turbo only $1,400. plus shipping. This turbo is good up to 675hp range.
The 3794 with my 68mm wheel is one of my oldest builds, it was originally called my 68mm Stg2 for the last 10 years. It is good for low 700-750hp range. Garrett was a little late to the party, lol. Let me know if you guys have anymore questions and I will try to get you taken care of!
Seriously guys for $1400 just buy marks... I know with balancing, parts and shipping I had more than $1400 into mine.
Thats what im thinking. Plus that’s truly around the hp and cost im looking at.
Now mark are those numbers on stock fuel/setup with your tuning? Or just intake and exhaust with a lift pump and tuning? And does this have or need high flow vanes?

Where exactly does the 3794 over rule the 68 stg2 r then? Everything I have read, always leaning away from the 3794 but you still sell them. If the 2.5 lly based turbo you sell is faster then stock spooling and flows better, why would others just not purchase that, then if they want more, purchase the 68 stg2r?
Theres a small gap of info I am missing.
Because people always thing they need bigger but most don't have the parts to support the bigger options. You always want to chose the turbo that will be at 75-80% of it's ability at your peak goal because it will keep it fun to drive. If you go too big then it sucks everywhere. The difference between the 68mm 3794 and my stg2R is the turbine size, the Stg2R is a 2mm larger turbine which is great for topend power but not as great for lowend power. The highflow vanes are great for tuning and they flow more air at the same vane position which translates to angle of attack on the turbine. Hope this helps guys. Thanks again!
I do and as far as I know I am the only one that actually stocks them on the shelf also. They are $499.
Is the stock 3794 wheel on the tipping point already, as far as spool up? I'm surprised a hair bigger turbine on the stg2r wouldn't help out the low end. Yes there's more mass to move I suppose, but also more leverage.
Is it 2mm bigger on the inducer and the exducer? Or only one?

The problem with the stock 3794 compressor wheel is that it is a 68x94 fat hub wheel that was contoured down to 65mm and that is a big no no. This issue with running a larger turbine is yes it is more leverage but it also lets more air get past it before it forces it to work so it causes more lag especially at cruising speeds so it is a trade off. It is larger on both measurements. Turbos are a balancing act.
Mark is there a better drop in wheel for the 3794 without killing the low end or going to a 68mm?
