Practice makes perfect.

It's amazing what a dozen or so trips to the track can do for your ET (especially with a 6M car), even with no additional mods to the car.

 

With 4 trips to the track in a year I went from 11.9 to 11.5 with the exact same amount of power. Practice does help a lot.

 

You running stock axles??Slicks?DR?Tire pressure??
We find the Micky Thomson DR's with 17 psi of air give a good 60 ft.We pulled a 1.60 last week..

 

I ran stock axles with an 18in BFG DR at 23psi in the spring to a 11.68@120mph with a 1.70 60'

This time I had my ET Street 26x10.5x15's at 16psi and DSS axles and still pulled a 1.70 60' but it was only 38 degrees outside vs. low 80's last time. My best 60' of the day was 1.65 and no doubt with warmer weather I could launch it harder and easily pull off a low 1.6 to high 1.5.

 

If the track is sticky, you can do it in the cooler weather also.Are you doing your burnouts in 2nd gear?If not do so, it makes a huge difference on heating them up...Just get out of it if you experience wheel hop..Drive it like you stole it man!!

 

Yes...I do second gear burnouts and I heat them up plenty. It wasn't "cooler" it was friggen freezing out. I never get any wheel hop. I wasn't able to fully launch the $hit out of the car without wheelspin. With a warmer track it will stick.

 

Very nice showing Brian, on DeatschWerks injectors no less. Sorry I couldn't be there to see it. Was Neal there?

 

congrats! one of these days i will head to the track with you. Guess next year now.

Brian how much does your car weigh?

 

3325 without me in it.


Thanks Neal wasn't there. I'll be needing some bigger DeatschWerks injectors soon....

 

I weighed mine Saturday-3240 without me of course...

 

Our cars are pigs with turbo kits on them Imagine if we were around 3000lbs with the turbos...

 

Awsome times man! Thats impressive

 

I think he has hit your problems right on the head here, if your shifting 4 times to get down the track your wasting atleast 7 tenths of s second possibly more per run, has anyone tried starting in second? i will bet you can shave 4-7 tenths off your time if you launch hard and have the torque to carry the car at that gear ratio..
Remember the 4 second cars dont shift at all and most of the fastest one who do use glides (two speeds for those of you who arent around the drags much)
Since the Z's suspension isnt made for drag racing your gojng to have to compensate some how air bags and good slicks will drop you another 2-4 tenths and well what do ya know your in the tenths, lol watch for flying axels and drive shafts now!!!

 

I was 3125lbs with the TN kit and stock battery, with the Braille I run now that would have been 30XXlbs! But with lower peak power and a so so power curve up top. I hear ya though, I may do seats soon-Ive found some cheaply priced 12.5lb bucket seats but Im hesitant to buy seats I cant sit in before purchase...

 

Launching in 2nd in a Z would be retarded. You couldnt pull the 60ft times people like Brian are cutting, and would therefore be much slower down the 1/4. While 4 shifts isnt "ideal" it isnt a problem for some people...I have yet to even hear of 1 person damaging the Z's drive shaft in any form of racing.

 

Have you tried it? I believe with that gear ratio and the torque you are putting down if you launched at 3500+ rpm you 60 foot time would be better, and your top end speed would be about the same.
Alberto I will admit I dont have as much z experiance as you do however I have owned several sub eleven and ten second cars two with two speeds and one with a turbo 400 all your doing is spinning through first anyway, think about it a little bit more then give me an answer or better yet jump in your car and try it....................
The reason no one has broken much in the way of drive shafts and axels is you guys arent hooking, you spin through first and most of second, the key would be hitting the traps in third tached out ..Top speed would be lower but et i believe would be reduced also..

 

I disagree on that 2nd gear launch, you'd have to ride your clutch HARD and you won't get that leap forward you get from a good chirp and hook first gear launch.

 

I also completely disagree with a 2nd gear launch. I get full traction in first. NO SPIN WHATSOEVER and my 1-2 shift happens AFTER the 60', so I don't know how a higher gear ratio out of the hole would help me at all.

I've pulled a 1.65 60' in mid 30 degree weather on a manual transmission, indepentent rear suspension car with very little weight transfer. I'd say that's pretty damn good.

A second gear launch would send the clutch up in smoke on the first pass, not to metion it would bog REALLY bad if you just dropped it.

 

But alberto and the other guys are putting down over 500 hp they dont chirp the tire they fry it!! That why a 2 gear start makes sense with 500-600 hp 10 seconds should be easy if you have the right diameter tires and gear set up. The fact most of you are using 18" wheels says you have no clue about drag racing tire diameter and gear ratios..
But hey the the z wasnt made to drag race in i tuned my suspensin for conering same with the tires and wheels and im loving every minute of it i regulaly own much higher hp cars through the canyon where i live..
