How a Rocket Scientist Changed NASCAR: Dr. Gas X-Pipe & The 1995 Daytona 500

Watch on YouTube

What happens here

Upon receiving a request from NASCAR team owner Larry McClure in late 1994, commit to adapting the X-pipe design for a Winston Cup car. Fabricate multiple X-pipe test systems tailored to the specific dimensions and requirements of the race car. Transport these systems to a dynamometer facility. Install the systems on the race engine and conduct rigorous testing, meticulously measuring horsepower and torque output. Analyze the data to confirm a consistent performance increase, such as a 4.5 horsepower gain, demonstrating the X-pipe's effectiveness over standard H-pipe configurations.

Goal: Quantify performance improvements of X-pipe design

Tools and materials

  • Data Acquisition System — Recording and analyzing performance metrics from dyno runs
  • Dynamometer — Measuring engine horsepower and torque
  • Exhaust Tubing — Constructing test systems for the race car
  • Race Engine — Mounting and testing the exhaust systems
  • Welding Equipment — Assembling the exhaust components

What they say

1995. In December of 1994, I got a call from Larry McClure. And he says in his his Southern accent, says, "You make that I'm imitating this. Maybe I shouldn't. >> But do it. >> He says, "You make that work on a Winston Cup car?" >> [laughter] >> I says, "Of course." Two things. I was going to die trying or I was going to make it work. I made several systems for him to test, and they were around. And they dyno tested them, and they found some positive results. >> It looked different, but we didn't know what it sounded like. You couldn't tell with the dyno room. >> They never told us what they were, but I'll tell you what what we found what I saw with my own eyes. Horsepower got with the actual race car system would increase the horsepower by by 4 and 1/2 horsepower. I sent him these
