I finally encoded the runs I taped from Friday at Cali Speedway (best run 12.254) which is the first run on the video.
The other ones range from 12.2 to 12.4 and are shot at night.
I already figured out that my burnouts are bad because I'm not revving high enough....will try 5500 to 6000 next time...

Check out my launches and help me get a grib on the initial bogging so that I can improve my 60' (my best was 1.883)

Also be warned the video is about 30 megs so please do a right click and save as so that I don't get the bandwidth police on my ***...

Any input is appreciated. Also note that Cali Speedway is about 4000 feet elavation considering the tempurate and air density factors so my 12.254 at sea level would have been a 11.65...for those of you who will state that I was too slow

Your def not heating up the slicks. Why dont you pull the brake fuse and just powerbrake your car? Thats what I do, I tried doing your rev it up and let em spin in 1st method but that doesnt do it for me.

As far as your launches, on your second run I noticed you were holding revs a little over 4000 rpm's I believe then you seemed to have started releasing the clutch without giving it gas, so your revs dropped considerably and you bogged. Try letting the clutch out a little faster while giving it gas at the same time, you seem timid coming off the line. Work on your launch technique, because if you rbogging with cold tires, dont even try to launch on hot tires your car will fall on its face after a launch ever worse. And I think your shifting could use a little work, they were ok, but again you seem timid and shifted kinda slow, believe me every little bit counts. 12.2 @ 4000 ft is impressive I believe with a mid to low 1.7 60ft and some faster shifting you could hit 11's at that track. Keep practicing

 

I have the brake fuse disabled (put a little switch in there...) that's not the issue.

 

Just cuz you have that disabled doesnt mean its not the issue, your not using it to its potential. The issue is your not heating up the tires, just spinning them before staging. Why dont you powerbrake after you drop the clutch and just sit there and burn out a few seconds? After you heat them up properly you still have to launch better and not let the revs drop, just mo, good luck.....

 

Here's what I'd like to know. How the hell are you revving past 7k. I hope you have a built motor. 4k rpms is at 12 oclock on our tachometer. If you watch. Your shifting around 7200 rpms or a lil sooner.

So here's my questions:
Do you have a built motor?
Do you have an 05 with the higher red line?
Did you just bump your red line?

My best was a 12.2 as well that damn bog kills me. I wasn't launching at 5k tho. I'll try that this wed at INfineon. Also I think you should do a burnout. Like everyone is mentioning. You kept doing a rolling burnout. I would just stay in the water box and burn the hell out of em. Good luck with 11's..

 

OK, I'm reaaaaaly trying to do the burnout but I keep on hopping out of the box....that's why I think I need to revv higher maybe. Once I get the line lock installed this will be an issue of the past but I still would love to get this working right...I believe I need to 1) rev to about 5500 or even 6000 rpm and 2) hit the break much faster after releasing the clutch...any pointers on that are deeply appreciated.

I am shifting at 6900 rpm, I have the technosquare l-spec reflash that upped the limiter to 7100 rpm...I never actually hit the limiter and no it's not a built motor.
Now the nicest thing about this is that as of yet I did not have to shift into 5th because of it.

now how can we master the Bogg issue?

 

ha i solved that one. I have 11.5 width hoosier slicks and dynoed in at 260 and i have yet to bog on them. what you gotta do is spin off the line and let the slicks do there job. When i launched i took it to 5500 rpms and dropped it hard and let them spin. WIth you having 100 more hp than me its possible you wont hook right up as you spin off the line but you will get sick 60 ft's and with that extra power you will glide right into traction without any bogging. Thats at least what i do on slicks and i hope it works when im running N20.
BTW nice job with the helmet cam and good vid altogether.

 

Wow you are revving past the stock red line without a built motor or any work on the head? Hmmm I could use a couple extra rpms like 6800.....
Although I'd be worried because when it revs that high with that much power, the stress must be exponential by that point. Hmmm researching this one!!!!

 

I see you have an 05 but its an enthusiast, does that have the 300hp 7100red line motor like the G35 for 05. Maybe thats why. I don't know what would happen if I bumped mine to 6800.

 

I have the TS flash and routinely run mine to about 6900 on stock motor, no problems. mrtomcat, nice vid, keep it up. I hope to join you on the track soon.

 

It's the standard motor but my rev limiter was stock at about 6800. I first thought that my tach was off but after I got the reflash it kicks in exactly at 7100 which means my tach wasn't off.
There are plenty of people having this mod without issues, it's not that much higher and you don't end up bouncing of the limiter which is obviously not a good thing in the long run.
i guess time will tell on how the engine holds up

ps. I am very sure that the 300 hp 7100 version is not a different motor but a different tune, ipso facto safe to hit 7100 when tuned properly...

 

thanks, yeah I love the helmet cam, I just have to find a better way to mount the recorder so that it doesn't freak out when the car shakes too much.
It's a great analyzing tool, I've already noticed so many things on what I need to improve by just watching this over and over

 

thanks

I'll be in Irwindale this Thursday again. We need more z's at the tracks

 

rev up and drop it in 2nd to heat up the slicks, 2nd is long enough to do so.

you spin em in the water in 1st to get em wet, then pull outta the waterbox and burnout in 2nd. burning out is hard on the clutch no matter what, especially with sticky tires, hope you're using a 6 puck!

nice vid too!

 

ok, I'm confused....here's what I do: I pull in the water box and stop when told to. I shift into 2nd and wait for the signal to burn out. I revv to 5000 rpm, drop the clutch and hit the break while staying on the gas.

Are you saying drop the clutch in first and then shift into second while you're already spinning? This seems even more impossible to do without jumping forward.

Please elaborate

 

no what you should do is spin your tires in the water box in 1st gear to get them wet. Then pull up a little (out of the water box) and then come to a complete stop and 2nd gear drop it (hope your slicks break loose which they should) and you will be doing a standing burnout at a much higher tire speed than you were b4 and you will also get your tires alot stickier. Once your tires are like fly paper, launch your car with the intention to spin off the line and instead of spinning you will launch without bogging.

i couldnt do this with my car because i didnt have enough horsepower to do a burnout in 2nd gear with my slicks so i just did a prolonged 1st gear burnout til i thought the tires must be hot enough.

 

reason I started doing the 2nd gear burnouts was that in 1st I kept on violantly fishtailing where in 2nd I can keep the car straight...

Well, I'll try your method out on thursday, maybe I can get it to work for me

 

good luck, I think you got the theory, the rest is execution

waiting to hear more about your results

 

Burning out on slicks in a 6MT Z without a line lock is NOT easy...believe me...I attempted it a bunch of times today (and during multiple previous trips to the track) and never got more than a little smoke before I either started moving too quickly or the brake pressure slowed the spinning so much that it was useless.

 

I've been getting a bit better but not good enough got a 1.807 60' foot with a 7.778 et (1/8 mile) on thusday

My Line Lock Solenoids arrive on Tuesday so hopefully by next week I have those up and running
