I can't drive time slip
 

Well last night it was T&T at the local track, so I thought i'd go out and see if I could drive...Well the end result is I CAN'T or it's just the fact that I get no traction. It just sucks knowing your car is so much faster than these other cars yet you put on a poor performance, oh well here is the run down on what I ran. Granted my car is tuned to 28 pounds of boost, but all I could run last night was 20-21 pounds due to spinning at the top of 4th gear at over 110 MPH.


15 PSI run I make about 270 whp at 15 psi

Reaction: .7828
60 foot: 2.6032 <-LOL
330 ft: 6.3774
1/8 ET: 9.234
1/8 MPH: 88.18
1/4 ET: 13.6693 <-Sucks
1/4 MPH: 108.44


20-21 PSI run, even worse performance

Reaction: .6549
60 foot: 2.5700
330 ft: 6.2981
1/8 ET: 9.1602
1/8 MPH: 88.05
1/4 ET: 13.4990
1/4 MPH: 115.9

I think I should have trapped over 120 MPH at that boost level but it felt like I was on ice the whole track, I was on 205/50/15 Falken Azienez about 30 pounds of pressure. :vash:

I need to set up my 2 step launch control, and get some slicks...

Yeah, your conclusion is correct. You cant drive. Keep it up, you will get faster.

work on those launches man, a 2.5+ '60 is horrible for a FWD let alone a RWD. your car definitely has some better times in it. trap speeds of 115+ are very impressive in my book

What track in IL?

It was Coastal Plains Drag Way in NC, it's where i'm stationed now. The launch is killing me though it seems any higher rpm launch the tires light up, any lower I bog out.

What sort of clutch? You need grippier tires with fewer psi in them.

PS - You said "stationed". What branch?

Marine Corps, getting out in about a month :-D

I have a Spec stage 3+

I was told radal street tires don't really do much when they have less air in them because the sidewalls being so stiff, I really didn't care to find out either.

IIRC Azenis aren't known for having stiff sidewalls. Lowering the psi is worth a shot though, it's free, and you definitely need more traction.

Good luck when you get out, you have a job lined up right?

damn that moves

Good info, it will be worth a shot. What PSI do you recommend?


As far as jobs, I have applied to a few places. You offering a job? lol but i'll be medically retired, it will give me 50% base pay income plus medical and that good stuff and I can pocket the GI bill going to school in IL. So it's a win win situation.

Nope I don't have a job for you, I'm in the Army myself.

I'm no drag expert, I just know that 30 seems a bit high.

Nice trap speed.

FWIW, try lowering the pressures to 28 or 26, I haven't dragged on Azenis in two years but I am pretty sure I was in the high 20s when I did. Although they have a reputation for getting "slimy" when they are hot, definately put some heat in them, but they have 1.8sec 60ft potential if you can slip the clutch a bit.

I just think I need to work on my launches, after the 60' im good with the exception of me spinning at the top of 4th gear but I really can't do much about that other than get better tires. I would love to be able to cut 1.8X 60's though with them, can you explain how you did that...launch RPM, clutch anything that could help? Thanks!

I don't remember exactly what I was holding the RPM at, but I believe it was between 4K and 5K, slipping the clutch off the line (1/2 sec max). You'll just have to play with it to see what exactly works for you, I spent some time out on a county road in the middle of nowhere practicing slipping the clutch- it feels horribly wrong at first. I didn't have any issues with wheel hop launching on those tires, but my spring rates are pretty stiff if that even matters any.

need more rubber no doubt, i mean 205's and 300whp dont mix.

Power and no way to put it down = time to go back to the drawing board;)

Koto, that may have been a typo, because azenis, DO have a stiff sidewall, that's what makes them good for auto-x. lowering the pressure anymore that 30 may make things worse.

A few things that may help with the launch:

better tires, obviously. I'd try dr's before jumping to slicks
soft rear suspension
removing front sway

Since you have an ems, you can also mess with speed/gear based boost control.

+1 all the driving skill in the world isn't gonna put that kinda power to the ground with those tires. Nice times though, pretty quick miata you got there. :giggle:
