also some of these points may have been made but to be honest i didnt feel like reading every post. sooooo get over it.
1. you can go sub 2 second 60' on street tires.
here's a list of the top 1/4 mile ETs with street tires aside from #2 Z eliminator had drag radials.
MODIFIED - ALL MOTOR
1) jnaut ------------ 09 Base Sport 6MT 12.245 @ 111.81 mph 1.813 60ft street
2) Z eliminator ----- 09 Tour Sport 7AT 12.420 @ 114.37 mph 1.854 60ft DR
3) ts-c63 ----------- 12 Tour Sport 7AT 12.777 @ 108.23 mph 1.913 60ft street
4) secondnissan ----- 10 Tour ----- 7AT 12.856 @ 106.25 mph 1.944 60ft street
5) tranceformer ----- 09 Base Sport 6MT 12.860 @ 109.09 mph 1.921 60ft street
6) FPenvy ----------- 09 Tour Sport 7AT 12.899 @ 110.74 mph 1.950 60ft street
2. launching the 7AT does nothing from what i'm tested. anytime i've pre-loaded RPMs it just spins tire and costs you time. and thats with VDC off. there is really ZERO reason to do a 1/4 mile on a prepped track with it on. most times you'll get traction and the slightest slip with kick in VDC and bog the throttle to compensate. it's more effective to modulate the throttle slightly with your right foot to stay in the power and kill whatever spin you need to deal with.
3. the guy who said reaction time improves your ET someone please smack him.
4. please dont run a 1/4 in drive anyone  the ECU for the tranny shifting is awful when going balls to the walls. put it in manual mode, do some runs, learn your car ,and hit those shift points hard. you and your ET times will thank me later.
5. street tires dont need burnouts. drag radials and slicks do. i mean have i done a burnout on street tires.....yes who haasnt. and yes i have done mini one here and there at the track to clean off any debris on bad days there. no full smoking pouring waste of my expensive street tires ones.
6. use the paddles. there is no difference in their shift times but its safer and less motion for your finger to pull that than the time it takes to move the stick. everyday driving i use the stick and racing applications i use paddles.
7. on the start you want to drop the hammer before the green pretty much you're going to want to hit it on the last yellow. also this is very dependant on where you stage. if you stage deep (far up) then it will take less distance to break the lasers. shallow would be the opposite obviously. soooo depending on how well you react and how your car gets off the line (all done with practice) then you will know where is the best place for you to stage based on your car and driving.
8. shedding weight is fine but i got a very fast 1/4 with full weight (minus cats), full tank of gas, and not a single thing removed from my car.
9. i've never changed my tire pressure once when i got the track. how i drove in is how i race and drove home. probably around 32psi on PSS's. never had any wheel hop ever. you people confuse me when you say how much wheel hop you get in many situations.
any more PM me |
Thanks for the reply !!! Someone please get me some Band-Aids to help stop the bleeding !
I see where you are coming from ... I think you've listed all that you are NOT in agreement with ???
Re:
The list of sub 2.0's are the who's who of Z drivers !
And most are driving 7AT's...such as yourself...and not 6MT's
There is a reason why drag cars are automatics.
I didn't say that it was impossible to run 1.9's 60' times on street tires.
I was addressing the concerns of a new racer driving a 6MT...in a more or less stock car...
Just starting out the learning process of how the car works on the track.
I did mean to say (rather than imply), that
'around 2.0' would be more the norm to expect when you are just starting out with a 6MT at the track ... Probably should have been more specific realizing that this thread is inhabited by some serious racers ... such as yourself.
Hope that restates my post more clearly...
I arrive at the track with about 1/4 tank of gas as you do ... it does help with the traction ... I do, however, take out the spare tire and tools.
Some of the Top Z Drivers you listed also lighten their cars considerably.
Removing passenger seats and other excess weight including draining the Windshield Washer Fluid reservoir.
Their philosophy is that lighter is better...and evidently it pays off...and I do suspect that you don't get to achieve results like this without practice : practice : practice : and maybe a few other learned tricks as well.
The 1/4 tank of gas might also help with the wheel hop.
Consider yourself fortunate not to have experienced that awful situation.
I've had wheel hop with the Bridgestone Potenza's and the Michelin PSII's.
Gave up with the street tires and went with the M/T DRII's.
Problem solved.
Every situation is slightly different ... Track conditions, Temperatures, Drivng Skills, etc ... & Not every car is set up the same.
Open Forums such as this can be a learning experience for those listening in on the debates.
The debate about how the ET is determined is a good example ... someone learned somthing from that debate for sure.
I know I've learned a lot about my 'Z' as a result of participating in these Forums.
BTW ... Thanks for those who posted those Time Slips !!! AWESOME
