Wow guys, settle down...
Again, it's not a matter of "low horsepower," but rather "reliable and repeatable horsepower." .... Plus, the assumption is that once a spec car gets sorted, the owner would put a bigger motor and go for a record. So the challenge is really for the car builder.
Finally, I'll confess that I have a self interest in the challenge. Two years ago, I converted my daily driver into a salt racer as a bucket list project for three friends to go 200 mph. After we all got our "A" licenses, I started sneaking the rev limiter up and got to within 1-1/2% of the class record before I got too scared of breaking parts. The plan was to return this year with a higher gear and get the record. Then, since "that would have been so easy," I'd take the NASCAR motor out of the current car and go back next year to check off the 300MPH box in a new special construction car. We all know what happened this year. Now, since I only have so many seasons left, I'm thinking about taking two cars next year. A spec challenge means I don't have to buy another big motor, but keeps a little friendly competition.
Flame on.
Tom, Not planning a flame, but did you read that post...
What makes you think most people don't build a car, get it sorted, and then get serious to go after a record...
While I always shoot for a reliable engine, the difference between records and participants is the edge... and how close you are willing to run your motor to it.... where you are hoping you have a 10 mile motor, not an 8 mile motor....
If breaking the record is going to be that easy with your current car, get your red hats for you and your buddys and start building that 300 MPH car so you can get your blue hat next. If you worry about breaking parts you are in the wrong type of racing.
What if the spec motor is a honda 2 liter.... now your screwed
Just go out and race, be safe, have fun, go fast
