New 90% rule spin (1 Viewer)

[Buddy]

I have heard Paul Page at least twice say how "everyone" is happy about the new 90% rule, and how much money it will save everyone... They are completely spinning it to that direction without mentioning the teams that think its not good and it will cost them more...

If I remember correctly there were a number of teams that didn't like the idea, and thought that it will end up costing them more money at the end of the season... Am I the only one who had that stick out in the commentary?

Could you tell us which teams believe a higher nitro percentage will cost them more money? Teams will need to invest in new parts to go back to lower compression, but they probably still have a lot of parts that will allow adjustments (for example) to blower overdrive, and of course timing is not an issue. Reported parts life (especially cranks) on 85% was a disaster.
Let us know . . .

Jim, I'm not saying its going to cost them more/less money... I don't own a team nor see how they spend their money... As for who has said they don't think it will save them parts, there are a few teams that come to mind but I'll wait until I can make sure before I name them...

As for our team we are pleased with the return to 90%. With 85% you end up spinning the blower faster and the blowers have to be FLAWLESS, meaning more frequent rebuilds. you have to push more fuel through the motor also= bigger pump, more ignition advance etc, etc, added up it is very hard on parts and parts cost money.

What are you doing on the internet when you are supposed to be packing your car up to come to Phoenix right now? Yeah, and what the heck is that belly pan we picked up yesterday? Did you have a hand in making that thing? How are we supposed to copy that? We'll figure it out somehow. Looking forward to seeing you smile again!

p.s. Lots of teams are reluctant to jump back to 90% all at once. Many are moving slowly up the percentage or staying with their 85% tune-up hoping to catch others in their experiments on the way up.

I second what Curtis just said, plus the cost of the extra fuel you push through just to make it all work on 85

Did you hear Alan in the final still on 85 in Tonys car. Sounds like they still need some more laps to get the fuel system right for the 90

Connie said it would save him millions on his cars if they went back to 90. Some people think that when the crew chiefs say 85 in hard on them there not really blowing up every run but beating the parts up. Rods, cranks wrist pins and pistons. High compression and blower and timimg.

Doug Herbert had an interesting comment at the event at the museum on Friday night. He said that the best thing about it was that it made nitro a tuning variable again. Even when the limit was well above 90% they never ran it all the way, they used it as a variable -- run a little more in some situations, less in others. Now with it back to 90% teams can again consider it a tuning variable.

 

[Jay]

with out a dought it will be a tuning deal a few % is big should be good to see what happens.

a thicker head gasket is all that is needed to lower the compression

Bruce Mullins:
A thicker head gasket is all that is needed to lower the compression
Question: If a head gasket is changed, either thicker or thinner, is the valve train geometry changed also? And if so, are there any adjustments necessary to maintain the proper function, such as changing the length of the pushrod or changing the rocker arms?

No, they just reset the valve lash every time they put the motor together or after it is run.


I don't what the effect is on the cost, but it sure is better on the ears at 90%.

Buzzz is laying up carbon fiber as we speak so you'll have something else to install. Don't you just love it?

I just hope we get it finished in time. Oh, and that it fits. (I guess that would be important also).
