1400* on max effort tune WOT 110+mph (1/4mi)
Built trans tuning, way bigger injectors than I could possibly need (Exergy 60's) stock pump and a bunch of bolt on's to promote airflow, air density and fuel flow/fuel density
I could deal with those EGT's. What cause's some guys to have high EGT's with vgt turbos and some run cooler? Tuning? Injectors?
Biggest reason I recommend the 3794 was OP said he wanted to sled pull some. I love my twin setup. Granted I'm on a little different level.
If it were my truck S475 over stock. HSP offers a kit with that retains second battery and has a coolant temp sensor. Then throw on a oil cooler and enjoy it.
That being said for simplicity sake I like the 3794. It's drop in and you don't need to change anything you don't want to.
I will end up with a 3794 on my 05 before too long
I like the simplicity of the 3794 being a drop in replacment but I don't want to have high EGT's or be limited on the power level it's capable of. More and more I think twins due to these reasons plus the EGR delete. I'm a turbo noob
I like my s480 single. Its fun
I PM'd you on the DF the other day. Thanks for your help!
I have Marks billet 66vgt and love it. I tow a lot and turbo braking is very good. Great turbo to twin in the future. Spool up, power and low smoke are all excellent. I have dyno runs of 650+ HP. I would have gone with the 3794 if it was available at the time.
I like the idea of keeping the turbo braking. What kinda EGT's are you seeing?
Mark has some things up his sleeve with the 4094 lag. This statement might not be true much longer. He just sent me some new parts to try out.
I'm giving mark a call tomorrow. I'd be interested in this turbo
I'd do twin's or a modified VGT.
If you drive in town a good amount or lower speed roads, an S400 frame turbo is going to be doggy at any rpm below 2000rpm's if not higher unless you're doing a lot of shifting to be on top of the charger. The S366 I had was bad.
You do have extra piping with twins and can have higher oil temps but oil temps can be lowered and the power from twins is so smooth.
VGT's are nice being you can put larger wheels in them but yet still get good spool up thanks to the tuning of the vanes.
I've got a modified LLY turbo for sale if interested.
Modified LLY Turbo
This is just my option and others have different experiences/options.

This makes me think twins again. I don't think I'd like a doggy turbo. Would a S465/83/.90ar be this way? I've had someone say they run a cast S467.7/87 not sure on the ar and spool up is terrific. Would I need to upgrade my sticks to help spool up? He has 40% overs
Thank you for all the replys guys :chevy:
