Andy, you also run a fairly low rev limiter too don't you?

Its always good to try and be smooth with all your shifting. Makes for a much happier car. Plus, 5th gear is a long shift so its not going to be quick either way. I do run a short shifter tho and it really helps.

 

I sense a little sarcasm in your critique. HPDE is to improve driving and track skills. If you read my initial thread topic story you would see that this was experimental to see how it would affect my overall speed, time, and quickness out of the bulb into the straight away and turn 1. I don't have a trailer to take my car to and from the track so a broken tranny on the track is the last thing I want when I have to drive 3 hours to head back home. If you have nothing positive to stay or constructive criticism, keep it to yourself.

 

I was doing this at the beginning and provided me with the best results. Staying in fourth through the straight away at about 7500rpm before lifting, braking and turning into turn 1 actually regressed what I was doing. Thanks for the input.

 

same here. my 4th/5th syncro got very touchy the beginning of this season. i think the 5th gear syncro is a known weakness. new trans in and all is better.

like was said, the issue comes from loading up 5th gear at low rpm's, and it leads to engine damage not trans damage.

i have also now started running a little less boost in 5th as was mentioned out of precaution.

there is no reason at all to worry about putting the car in 5th.

 

I hit 5th in a few places at all three of my local tracks. If I don't shift to 5th, I'm going to bounce off the rev limiter and just hurt my time.



If I didn't have to arrive and drive, I would almost want to do away with my 5th cruising gear and just use 5th from an MR tranny or something.

Guilty. I just started getting the crunch when going 4 -> 5 at redline. I've been shifting this way for years now so take that FWIW.

Not happy about it, starting to think about transmission rebuilds already.

 

I had the 5th gear synchro crunch when I bought the car at 30k miles. When my clutch blew at 60k, I sent the tranny to Shep for a rebuild. I shift to 5th regularly on track with no worries.

 

Nice.

What does Shep do to the synchros?

 

7800rpm. I could probably go a bit higher. But even at ACC I'd still be shifting into 5th gear between 10 and 11. At RA I was going into 5th a LOT (obviously) with an average speed of about 100mph over the 4mile track.

 

a lot of it comes down to blueprinting/detailing/properly aligning the syncros. something that i dont believe was done too well from the factory. theres a good explanation on the jacks trans website.

 

Replace them.

I thought Honda-girl didn't have stock gear ratios. He shifts to third in a lot of place I wouldn't think I could. He is a much better and experienced driver than me.

This is just silly. If you're running novice group I could this as being ok but running higher run groups with other cars (especially German car) you'd be getting your *** run over down the straight in fourth gear. You should be entering the bulb at the top of fourth then scrubbing speed to apex then shifting to fifth just before the bump before the pit entry.

Lightning is a fast track and fifth is used often.

 

Your senses are top notch. Your reasoning on the other hand...

You are tracking your car and are affraid to get into a gear because it may break, cause a guy in 300z said so.

Ive been doing hpde in north east for a few years now, and I drove to and from track in my evo pulling a small trailer with wheels and equipment. I know how you feel. But improving skills also means pushing car to its limits. And you should understand that sometimes it means sh•t breaks. If you redlining 4th in the straight you should know this is not te fastest way and you must shift to 5th no matter what you have heared. Im assuming you are improving your skills to go faster not slower. So shift away and what will happen will happen. Otherwise go for a nice cruize on belt parkway, and practice without worrying something will break

 

"Ultimate ratio" is Evo 9 1st a 2nd, and Evo 8 3rd and 4th gears,and 4.11 final drive. He doesn't have the 4.11. So the gering is no different that an Evo 8.

 

This.

I use 5th on both the Bridge straight and the Main straight.

 

I'd second that also.
