So after finally getting a built motor, cams, heads, new injectors, and a fore fuel system, I decided to put my car on the rollers to see what it would make on E85. This was with a 4.25" pulley and a D1SC head unit. Today unusually hot (90 degrees F) and the DA was pretty bad (2500). Took the car for a spin after the session was over and man does it rip. Lund got it dialed in good. Also the shop owner said that his dyno reads lower than it used to due to a software update so it should be close to 850 whp on a Dynojet. Happy with the numbers nonetheless.

Very impressive power, and I can well imagine how it felt to do the first drive after the tune. The motor sings!!

Funny thing is after reviewing the logs, is before i had the built motor i was making 13 lbs of boost. After the built motor and change from a 4.5 to a 4.25 pulley i am still making 13 psi. Maybe i should go to a 4.0 pulley. Thoughts.

Not back from vaction yet but was able to find these pics on my phone. car is basically the same. Only difference is I added a UPR breather/catch can setup instead of the breather filters on the valve covers.

The 13-14 S197 is the cats ass! Car looks dope bro!
Thanks. Yea i agree. I had an 11 v6 before this car and so glad i traded up for it. Plus the features like the premium lcd dash and select shift make it worth the upgrade. Hoping to take it to the track and see what it will do next weekend

Also I'm back now so figured I'd post an up front pic of the engine bay. It's a little dirty but you get the picture

I see no reason to not go with the 4.0 or 3.88, I'm running the 4.13 on a stock longblock. Your built motor breathes better which is likely why you havent seen a boost increase.

So I ordered a 4.0 griptec pulley from lethal performance over the 4th of july weekend. Installed it and also did the roush lower grille delete to let my intercooler breathe as much as possible. Hopefully heading back to the dyno to see if I can break 850 wheel.

Great results, congratulations! Your car looks very nice, too... I am not that familiar with centrifugal blowers, but believe the coyote procharger has a dedicated supercharger belt, correct? Years ago I had a reverse rotation D1 on a car with a single belt, and it would go through belts frequently... After my last road-side belt change in the Phoenix summer heat, I told myself never again! It seems the new systems have likely solved this issue.
