LQ4 408 results Dynoed my 408 the past 2 days engine is a 408 LQ4
heads TEA stage 3 318
intake Edelbrock Victor jr
carb CSU E85 750
Engine was dynoed and tuned by Darrell Makins @ UnderPressure Performance in Spartanburg SC.
First day was break-in and dynoed N/A with a dyno mule 750 on 93 pump gas it made 589 hp @ 6700 518 tq @ 5500 pretty good for a 9.9 to 1 turbo motor.
Then we put twin MP T-70 turbos on and changed to E85 it made 1068 hp @ 6700 and 12 psi 853 tq @ 5500 and 11 psi.
Didn't add any more boost because of boost creep I'll fix the wastegate piping and put about 15 psi on it and take it to the track and see what 1200 hp does.Pretty good for a truck motor and blow thru on top of that.
