Kind of behind on this post, but here we go.....Spencer has been reporting the 8 team capacity at TRD for some time. Eight stretches the resources of the company, but is doable. I believe that 6 is the preferred number. Why is Spencer reporting 8? Because TRD will support MWR and JGR if they both were to go to the maximum 4 cars per team. In essence, they wouldn't say "No" to Coach and "Yes" to Mikey. In reality, JGR will always have room for expansion with TRD to 4 cars--that is priority 1. MWR's role is negotiable as they rely heavily on Toyota for support.
As for the idea of bringing Petty Motorsports into the fold? There is no question that Toyota would want the biggest name in NASCAR as part of the family. We saw that this was crucial with DW, and would bring cartwheels to both upper management in North America and Japan as well. For reasons other than team strength, there would be no question that Toyota would welcome The King. Having said that, I feel that JGR would have to be okay with the move as well. TRD does not want to do anything to piss Coach off. The other thing to note is that with a smaller number of teams, JGR has a degree of exclusivity with TRD. Kind of like an Engine/Engineering Shop that they don't have to pay for (or pay much for). It is common knowledge that communications between JGR and MWR had to be fostered, and had never been automatic. JGR likes to keep their stuff in-house as does any big player. Toyota/TRD has to be careful here--they do not want to jump at the temptation of landing the biggest name in NASCAR, and lose a big dog in the Championship. They will not sacrifice Coach for The King IMO.
Another crucial thing to note is that performance of late will play into this in my mind. TRD would need to show Coach that performance wouldn't drop off with more teams. Performance has sucked lately. This has the potential of flipping the question....Instead of "Will the performance suffer with more teams?", the question might turn to "How can RPM help make all of the teams better?" Tough questions to think about.
Sliced--In terms of building capacity.....TRD pretty much siphons money from Toyota NA, and Toyota NA and Toyota Japan pretty much leave TRD alone. All NA asks for in return is some evidence that participation in NASCAR sells cars. It does. Thirty percent of all Toyota buyers note the NASCAR participation as at least a partial influence in their buying decisions. Toyota NA is happy with that. Toyota Japan is more interested in image. Are we winning? They want a Championship very badly, and they have taken it hard that they don't have one yet. There is pressure. So, TRD pockets are not as deep as guys like Jack Roush think given that TRD and Toyota are really two separate entities. This limits the number of teams that can be supported in addition to the fact that you are looking at a staff of 200-250 in Costa Mesa, and I believe a smaller staff in TRD NC. Do not forget that TRD doesn't just build motors. They also assist teams in chassis building, engineering, race support, etc. That staff of roughly 400 or so is pretty small with all of those responsibilities. The other piece to consider in taking on RPM is TRD's ability to respond to problems such as the massive ones this year in a timely fashion. More teams--longer turn arounds. Again, JGR is crucial here. Any depreciation in the quality of support would be devastating for TRD and Toyota in terms of its relationship with JGR. Once again, in the context of the subpar performance this year, it would be a hard sell to convince Coach that all will be okay unless RPM is bringing something to the table. One last note in terms of what teams are charged for their engines, etc......That question needs to be answered with another question...."How much is it worth to TRD/Toyota to have JGR in the fold?" Words can't express the significance. So, in a nutshell, I'm betting that Coach doesn't worry too much about the engine bill. Mikey probably worries a little more.
So, there it is folks.......
