A few years ago a client of mine owned a Trans Am team. He ran a pair of Mustangs. He asked if I could come to Las Vegas to help his pit crew. Full disclosure: I was just helping.

His team leased engines from a shop. Knoxville I believe. Part of the agreement specified no member of his team could touch the engine (not sure if this applied to carburetor adjustment). Between each heat someone from the builder would come by the garage and run the valves.

W/regard to NASCAR, do the teams who have a third party build their engines purchase or lease them? If the latter are there restrictions as to what they can do yo them?

Teams that don't have an engine shop lease engines and the engine builder supplies a team that tunes the engines, changes valve springs, sets the timing etc., at the track. They cant do it themselves.

Lease. And there's even different tiers, like you can lease "A" tier engines from HMS or "C" tier.

I think they only build Chevy (top tier) engines, they dont mess around with the lower tier Toyota and Ford stuff.

Very interesting, wonder what crew was doing all this for Ross earlier this year? HMMMMM!
 
Do they still take random cars and dyno the engines as well as inspect them? I'm assuming that all three manufacturers are really close in power and NASCAR would like to keep it that way.

I know last year HMS still had the "B" level engines because spire was using them in at least the 77. You could tell when the 7 ran a "A" motor because his performance definitely picked up.

I am starting to think we may have lost a little bit of our edge here at RF on push rod lengths. We were on the cutting edge a couple of years ago on our PRTs (Push Rod Theorem's) in terms of knowing what was needed in terms of length and PRT strategy per track.
.
If we can loose our edge here at RF on anything it very obviously can and will happen at any intellectual center or enterprise in the world. I fear that is what happened to HMS verses Blaney. When they got down to the final four Blaney and his team obviously had the best PRT working for them.

It is all too clear that the teams are reading us and looking for guidance and wisdom and they forgot about their PRTs after we went silent on the topic.

They take cars pretty regularly for teardown, and a few engines each year for the dyno. Looking through Pockrass’s feed this year it looks like they dyno’d engines after the Coke 600, Michigan, and Talladega last month. All three of the championship-winning cars had the engine torn down this weekend too.
