On the subject of R package and SE cars having better internals it's quite feasable they picked the rods cranks blocks etc. that were closest to the blueprint and used them

Let's end this retardation right now. The origins of this myth go back to a magazine test of an R back in 94 or 95. The R ran .1 sec quicker 0-60 than the M of the same year. M.net morons then take that to mean that the R car must have a hotter mill.

Let's examine that a little. The stripper (read: base) R-pack with stiffer suspension runs a little quicker to 60 than a fully optioned up pig with crap suspension. Hmm.

You can thank our friend Don on m.net for coming up with this, as well as other gems such as shocks don't effect ride quality.

I would not be surprised if the manufacturer's test car they send out to the magazines were more carefully assembled than standard production models, but Mazda doesn't have the resources to expand that to production cars. This is not Mercedes AMG here.
The only car I'd believe might have a chance of having a tighter than standard motor would be the Club Spec cars, and even then I doubt it.

^^^ I agree with your assessment; I was about to write something similar.

I believe it. Clearly this guy is capable of some very serious builds. I am really impressed with that motor. Built from scratch, and designed specifically for drag racing.

wow this thread reminds me of how easily i bent my rod thsi summer. 200 rwhp and uneven compression across the cylinders is all it took for me.

Another reason not to believe the R-Package crap, my car is an R-Package and did that. Just saying.

not that i have much weight here... but i agree, another naaay. A robot drops that motor in. I believe there are some that are better than others... but its luck of the draw

I think its def power, not det... a yay.

Maybe the reduced rod length lowered the compression ratio... therefore reducing cylinder pressure... lowering the forces the rod sees.

I know some "old school" engine builders that have seen it all... Im going to ask them if they have seen motors run strong like that.

Not heard the rumour until this thread just know that it wouldnt be hard to do from a manufacturing point of view cost effective is another story.
Totally agree with test cars fully blueprinted engines/ higher boost leaves the press raving
