You may have seen this car on my Youtube channel on it's previous trip to Atco go 11.50 on the brakes (99 to the 1/8th ). The owner, like many others, wanted a chance to finally spin the rollers since it's only been road tuned.

First spin off the street... 538hp @27-26psi (Straight wastegate)



Got afr's in check, installed the boost controller, and set peak boost to 31.8psi...






At these power levels, it just makes sense to run real gas or at least meth. We took the time to have a team meeting and let him hit the streets with 28psi and 568hp.... Took a 4th gear run to make sure everything was on par...






On a side note, for safety precautions, we have a boost cut set around 33psi. While adjusting the boost controller, we hit the boost cut, and I wanted to share just how fast this combo hits 33psi on a 'soft' pump gas map in 3rd gear!!

You can see the blue and burgundy lines on the graph end around 5750 rpm.



Turbo lag is overrated. Good things come to those who wait!!!
