Running a 9second pass..........
Here are some guidelines. I would start around 12 PSI. My car seemed to work best around 11 psi, below that and it skated around on the big end. Are your rear shocks adjustable?

Thanks! I have 32 way adj. coilovers. I have the front almost full hard. I was playing with the rear Saturday. I started at 14 which is too hard, i know.
Im going to start out at full soft next time and work my way harder if it bottoms out.
I don't know a tremendous amount about IRS cars but i would imagine you would want the front as soft as possible (rebound) and the rear stiff (dampen) to plant the tires and transfer the weight of the car onto the tires. I am sure someone will chime in and confirm or debunk this.
This is from the proper suspension setup thread.

Dan: With the Supra's we had to gradually stiffen the rear as we made more power. We didn't change the setting at all from 800-900rwhp but at 1000rwhp we were in big trouble. We switched to a stiff sidewall slick and set the rear up really stiff. That was fine until 1200rwhp.....at that point we lightened the car up a little and corner weighted it. Then put ballasts back in and slowly started stiffening it up. Our car weighs 1000 lbs more than yours and makes more power but it's all relative.
Have you corner weighted your car? Do you know the front to rear ratio? You could either try and lighten the rear of your car or add some stiffness. If you lighten the rear with a hatch or something you could then ballast it back where you need it and adjust the shocks accordingly.
You might already know all this so sorry if i'm outta line. It's late and i just got in from hanging out.

Need to allow the front end to go up transfering that weight over to the rear helping with traction.
How much boost are you getting with anti-lag in 1st gear?

Depends on how long Im on it. Usually around 14psi. If I on it less it will build less.
I know this may sound like blasphemy in this section, but have you thought about turning the power down a bit to get your launching sorted out? You've got the MPH for a mid-low 9s pass, so if you turn it down a bit, get it sorted out at that power, and then turn it up slowly it may yield better results.
Also, I can't remember what EMS you are running, but does it allow for any boost-by-gear, or boost-by-time settings?

Ernie your probley getting tired of getting advice from guys like me that dont run as fast but were pulling for you and trying to help!
The 11.5 et slowed down my 60 becouse i dont have the torque you have so they should help, soften up the front to get the transfer and i would keep the rear about 3/4 stiff to start, and if you can stage the wastegate and bring all that power on latter in the run then it would be more manageable.
From there its seat time and what the setup tells you it wants!
You will get there becouse your determined and not quitting which is probley why you can afford to keep trying!
Anyway good luck and have fun!

I'm sure with the anti-lag you get boost instantly and possibly getting higher boost in 1st gear over no anti-lag.

Seriously is that an option?
I did highly recommend it to a customer with a 450 hp SSR that has ridiculously unnecessary 4.56 gears and consistently running crap times.Congrats Ernie, you're already there for all intents and purposes. But your camera man SUCKS!

ET streets in my opinion don't belong on a car at that level in my opinion.
Put some slicks on it and figure out how much power it needs to launch safely without bogging or breaking. I don't know anyone with a true 7-9sec rotary that needs antilag to leave the line. On a proper setup you can make more boost than the tires could handle just on the two step.
The rest have to do wth the driver's right but more so left foot clutch control!

ernie iam just curious what did you change between this video http://youtube.com/watch?v=HZ3HTrQ-WEo
till now??? because your launch and 1-2shift on the old video looks alot better then your present situation.. u still spun some, but it looked like you were doing much better out the hole then where you are right now, if you paired that launch with the way your car is running now you'd be in the 9s for sure! goodluck hopefully you knock down that 9sec barrier soon, u deserve it

Thanks for the help guys. That last vid posted, Ray let me borrow his Koni drag shocks that Peter had made, but they are getting re-valved for his Time Attack car. Im considering the the HKS Drag Coilovers. Right now I have the HKS Hipermax coilovers.

dont put the slicks on with the fd tranny, carnige will follow.. not to mention you will get used to how the car drives on slicks then when yor competing with the et streets you will have to re-learn how to drive the car ...when i used to run the et streets(reqd for the street class) i would launch on 10 psi with the tires @ 12 psi.. it netted in the foot time range.the car weighed in @ 2,800 with driver ..
your getting there i think your right around carl's times arent you? anyways nice #'s T-DAWG

Hey Ernie.
I don't get on the forum as much as I should... Congratulation on the weekend, I'm sure you'll make it happen next time out. I can already see it, you and lee going back and forth... hahahah funny!
And by the way everyone's signatures are looking...
IRS record is coming to a new home!!
