Nope, not at 124 MPH, there is some HP missing. Needs a bigger carb and jetted accordingly. You might be surprised how big of jet I have in an 1150 dominator to give it what it needs.

First calculation I assumed the 3220 lbs was race weight. It should dip in the nines if everything is playing nice.

Little more weight...

Your ET / MPH computed from your vehicle weight of 3480 pounds and HP of 660 is 10.14 seconds and MPH of 133.30 MPH.


Give it fuel and air and let it eat.



Well I know the carb is fine. That is the carb off the Duster and its been in the 9.70's already with a quickest pass of 6.14 in the 1/8th.

I am half tempted to put this engine on a dyno and see WTH is wrong with it. I will check the cam first as I had trouble with #8 intake most of the summer until I replaced the adjuster...Since then it has been good.
