Stock/SuperStock Teardown
Although this is always a controversial subject, perhaps its time to move
forward on this, and realize it is not 1980 anymore. Presently, I have seen 3 different types of teardowns. 1) Where carbs or throttle bodies have been checked, camshafts have been checked, and the entire car has been given the once over. 2) The more traditional teardown where all the above is done, plus removing a head and having it poured, bore & stroke, etc. 3) The traditional teardown Plus pull the motor, check cranks, rods, pistons, blocks, etc. While we like when our competitors get a 2 or 3 teardown, nobody thinks it happens often enough. I don't know that we have the ability to change that. NHRA does it when they want, how they want. To make it easier on everybody physically & mentally, I think we could be a little happier, if all Class Winners, LODRS Winners, and National Event Winners had at least Teardown # 1, PLUS, an inspection with a camera of the cylinder, piston dome, valve reliefs, valves, etc. This would be followed by a P&G to get total cubic inches. Perfect? Not by a long shot. Better, I think so. At the very least, it's a thought starter that you can add to, modify, or maybe even like. J.R. |

Re: Stock/SuperStock Teardown
I think you are on to something. Borescopes have gotten very good, very small, and very cheap. It would be quick & easy to take a look at intake runners and ports, for example.

Drain oil from pan you can scope thru the drain plug and look at crank and rods.

Re: Stock/SuperStock Teardown
On my dirt motor (IMCA) we have to have site plugs on one side of our oil pan for inspection. Like the ideas mentioned above even though I do not drag race anymore. It does and will keep everyone honest.

Re: Stock/SuperStock Teardown
IMCA like Nhra lack tech people with knowledge, they both once had pre tech, not so much any more.

Re: Stock/SuperStock Teardown
Just started getting involved with dirt cars. The IMCA and street stocks take the top 3 after race and tech them what they wanted to see. One night it was all 4 shocks, go no go gauge in 2 barrel carb was used once, front spindles and heads have to have IMCA stamped on them. For a 200 to win they are getting checked pretty well.

Re: Stock/SuperStock Teardown
Running a Limited Modified and some tracks do not look at much, others look at everything, especially in big money races we can expect to take a head off, carb inspection, suspension etc...
And they also take a coupon of our Hoosier Dirt tires and test it for doping or mysterious substances on the tires (Mainly right rear) Last edited by nickh; 03-13-2024 at 11:36 AM. |

I follow all 3 drivers that had tires in violation, hate to see this but all racers have been warned many many times about this. All I can say is their tires coupons taken (3) came back with violated integrity of their tires. They tested 3 samples off of tires on 67 different racers and these 3 racers tires did not pass. Huge fan of all 3 drivers. A.J. Foyt once said "you ain't cheating till you get caught". LOL Here is video of CEO of world of outlaws address this. Last edited by nickh; 03-14-2024 at 09:13 AM. |

Re: Stock/SuperStock Teardown
Nhra doesn’t have the time or man power to tear people down
Also the 130 under is the new automatic teardown why is that So there is Less teardown of competitors There rules to live by
