Gotta agree with Ron on this one.

Just got back from Dyno week and came up with some new questions.

Tony Oddo finished up the "refresh/repair" of the Mustang motor. Dyno sheet is just maybe half a horsepower lower than before. I'll take that!

Since you granny shift at 4800, what's the peak power matter to you?

Yeah.... Charley told me that things last longer and are less expensive if I don't wind it out every shift. Obviously he lied! I only drove the car 3 times and I'm having the motor rebuilt - the tranny is worn out... and needs dog gears and something else... and I've blown through 2 sets of tires. WTF -- from now on I'm going to start to drive it hard!

BTW -- I only pick up 10 ft lbs of TQ from 4800 to 5800 so WTF why rev up the motor for a lousy 10 ft lbs!

because the rpm drop upon shifting puts you down around idle.

Yeah -- that whole shifting thing is an issue....

McGee just called ----

Turns out that I also have cracks in my shifting forks! So it's a good thing I asked them to tear into the tranny. Lose one of those and we'd have a major issue! The dog rings not so much - but pieces breaking and going into the tranny (meat grinder) wouldn't be a good thing. So $1500+ in tranny parts can be added to this little excursion. The motor refresh was actually cheap IMHO @ 6 grand. Funny -- the ONE valve -- $130 bucks!
