Well guys I figured I'd share a little review of my current truck set up in case some of you out there are thinking about going this route. I got a 16 LML that I decided to put a Wehrli S366 SXE kit, 10mm CP3 w/ Wehrli Race conversion, & Pro Fab Manifold and Up-pipes. I did not do the install on these components so i have no feedback on that as i trust my abilities to wrench to a certain extent, but the Fleece youtube video of the CP3 conversion gave me nightmares so I decided to let a local shop do the install where the owner is running the same set up above but with a S484 compounded over the S366.
My first impressions when picking the truck up was that it finally had that deep rumble sound like a diesel is supposed to sound. The truck sounded amazing at idle all they to WOT. The only downfall was drone since i was straight piped at the time. Holy wow was it bad, not even a comparison to the stock turbo. I installed a 17" FTE resonator a week later so i no longer have that issue thank god.
Turbo spool of the S366 SXE is pretty dang good compared to the stock turbo. I can tell it spools slightly slower than the stock turbo, but it is not much at all. The truck does smoke a fair amount until the turbo spools when getting on it from a stop or rolling into it, but clears up well once it lights. Power wise the set up is pretty stout for a daily driver/budget street truck compared to some kits on the market. I plan on compounding the S366 down the road, which is why I went with the 66 over the 69 and a little quicker spool. If you are looking for a S300 single application and not really worried about towing heavily and just want a fun street set up with $$$ in mind i wouldn't be scared to go the S369 route with the way the 66 spools.
Temperature wise at WOT i see the EGT gauge on the Edge max out just over 1400-1450 ish, Cruising EGTs around 60-65 are around 750ish with 1-2lbs of boost. Overall I am very impressed with the way this set up performs and the quality of all the products and powder coating involved. The plan for the truck is to have the trans built and 60% injectors then if im still wanting more put the big brotha S484 in the mix then start buying motor aprts
. If anyone is wanting anymore information i didnt touch on let me know and i can try and get some videos or answer any questions you have.
