Great job! Those look like excellent times for us 6 speed guys. Do you have a lot of experience racing stick shifts or are you just naturally gifted? How about some details like what tires you were running, outside temp, and any technique, tricks or tips for the rest of us.
Tires are nitto nt555r launching at 4500 rpm and shifting at 5800 each shift
This is the first manual car I have ever owned only experience with stick was my mothers diesel truck backing out of driveway. Outside temps were closer to 70*
ummm, and how do you manager that? Ive tried this and at full throttle, the car doesnt want to come out of gear and if you manage to get it out of gear, it certainly doesnt want to go into the next gear.
I'll grab the shifter after Im moving in first and gently pull it towards second when im nearing redline. It wont come out of gear since Im flooring it. When I hit clutch- its a quick stab and release about halfway to the floor- the shifter will drop into second. Its pretty quick. Then I'll do the same to go into third and fourth.
the only problem is if you dont stab the clutch far enough. then it comes out of gear and doesnt go into the next. kind of embarrassing
I've launched my srt8 twin turbo as high as 5k on stock half shafts with no breaks. In fact over a weekend I had 20 passes with launches between 4k and 5k.
Now the real kicker is when I had minor mods and 7 day off the showroom floor I broke the stock half shafts 3times over a 60 day period...and this was at a time when upgrades for the axles were all but nonexistent. I did upgrades and broke those too.
It seems that the launches best at 4800rpms, the car hooks and I get 1.85 to 1.80 60 foots. My time slip is posted in the 12 second club best time was 12.14 the car will do 11 s but I am still tweaking tunes and suspension.
The tip or trick you are looking for is the fine line between quick slipping and side stepping the clutch. Do not side step the clutch, just let it out fast and smooth and give throttle equal to half of what your clutch release is...you will shoot out like a rocket if you don't get pushed back in your seat and the hair doesn't stand up on the back of your neck you either slipped the clutch too much or you broke an axle.:thumbsup:
Speed shifting is easy you will have a rougher time convincing your mind to not lift which is the discipline. Shit at 5500 to 5800 Rpms don't lift off the throttle. I recommend 5500 to start with as this will provide you 200 rps of error if you've increased the rev limiter to 6800 then you shift at 6000 but I don't recommend this unless you have mastered the speed shift at 5800 Rpms first. Essentially at 5500 you have to shift fast and the car will jump to 6000 Rpms before the shift is finished. At 5800 there is no room for error unless you have increase the rev limiter. Onnce the shift is complete the car will lurch forward and continent accelerate you may chirp the tires this is normal. Speed shifting in our cars is worth about .50 on the quarter mile, unless your stock then it's worth about .30 on the quarter. I've never ran an eight mile track.
The 12.14 I ran was shifting like granny. I was feeling out my turbo setup and ran a that time which was better than my days average which was 12.30 @ 11# s with a da of 1700. Last Saturday I ran 12.40 with a da of 2700 and air temps at 75+ degrees. Btw I run nt05 rs 325'sx40x20.
Your milage may vary...that's my experience with just under 100 passes on my car:redcap:
Question to 1320 owners. What's the maximum RPM achieved when footbreaking? Looking for the highest RPM that the car can be launched. 2300, 2500, 2800? Same question when using the trans brake. I have been told the 1320 has a higher stall converter than the Scats but can't find the...
I am driving a 2016 Scat Pack with CAI, catback exhaust, and 85mm ported throttle body. Haven't gotten the money up yet to get an unlocked pcm and tune. I have tried several runs at the drag strip and can not get a good 60 foot time. Running 305/45/18 Nitto NT05R's on the back. Tried everything...
I just got back from the track for the first time in 2020. The DA was pretty terrible (our elevation is 2300 fasl as is, the DA had us at 3300), but the track wasn't busy at all, so I took the time to focus on dropping my 60'. I'm running a set of nitto 555R 275s in a 20" wheel. This is my...
I use my '15 6MT R/T + Shaker for a daily driver and have had issues with notchy, clunky shifting. Many have suggested the Barton, which I love the feel of but seems to get stuck more than the stock shifter. Barton seems to think it's normal for it to be like this because there's less rubber...
