I know you are all probably against gas guzzling trucks and racing but thats why this is hypothetical  |
It's one of those 'it depends' kind of situation.
Power-to-weight ratio tends to dominate in drag racing unless you're talking about Top-Fuel,where 300 mph is obviously impacted by drag reduction.
The 'aero' kit on my T-100 added 820-pounds over curb weight, and allowing for the weight addition and stops along the trip route,worked out as 40% mpg benefit.So your cap it certainly going to help your mileage.
As to drag racing,even though I was 300-pounds heavier than stock,I out-accelerated the stock pickup and reached a higher velocity as well,and this was on damp salt which was costing other normally-aspirated cars 13% in top speed.
So I think,that if you have the power,even in a 1/4-mile,that you'd probably outrun your present truck.
