[Fot] 89MM piston question

[Paul Ricco]

FOT,

Large companies in the US have put so much focus on having their employees compete against each other internally that most employees have forgotten who the true competition is… the people that represent other companies.

It would be great if the TR community continues to openly help each other keep the TRs completive against the Volvos, the 356s that sound like formula cars when they rip past (guessing none of them have a single compliant parts on them), MGs, etc.

It would be great if FOT could remain a forum where people could ask questions, get honest answers from those who know, and people did not get smacked by someone who does not agree with them.

It would great if we stayed focused as group to kick ass over the marques that we race against, instead of kicking each others' asses every time a question comes up.

Even in the highly completive world of professional motorsports, the factory works teams that care about their marque's success do a tremendous amount to support privateers on and off the track.   They focus on beating the other marques first.  I have personally witnessed the Porsche factory team hand parts to a privateer at an IMSA race.  All done that so the privateer would start and finish the race successfully.  All done to promote the marques over other marques.  We have a lot of fun at the track when the TRs are all doing great in their respective classes over the other marques in the group.

Have a great labor day weekend and I look forward to seeing a group of fast TRs at RA in a few weeks.

I blew a head gasket last time out, compression into the cooling system and blew off the bottom hose. I guess it wasn't tight enough, and scuffed two pistons before I could shut it down.
