Running a 9second pass..........
AIN'T AS EASY AS EVERYONE THINKS! For all the keyboard warriors that would rather type in " YOu have 700+hp, running 9's should be a cake walk"......Go spend the money, build your car and run 9's. Till then, zip it! lol....
As you can see I went to the track again today. I got six passes in. Tried dialing in the suspension. Turned out I have to adjust the anti-lag for less rpm as well as make the rear softer. But I got alot of good seat time. Im spinning so bad in 1st, when I hit 2nd, the car hooks up and falls out of boost totally. I'll get there. It was about 95degrees out today, so my mph was a down a couple. Last pass I hit 146mph though. Average 1/8mph was 115mph.. My mph was all over the place in part due to me trying to shift at different points to see how the car reacted. Here are the passes.... http://www.youtube.com/watch?v=IZpSKbyEPlM http://www.youtube.com/watch?v=BnrGoMv_Czo http://www.youtube.com/watch?v=h6_WZlX1OKQ http://www.youtube.com/watch?v=mbXjlBbqahQ |
Good runs Ernie, and nice MPH, what 60 ft were you pulling? I saw you were bouncing off the rev limiter in first to get your speed up so you wouldnt land too low in your rpms in 2nd gear and bog down because you were spinning bad in first gear. Watch what your mph is when maxing out first gear and if you spin next time, keep in it until you reach that speed, then hit 2nd and you will land in your power band. But by next time, I know you will have your suspension worked out so it will hook and go!! Good luck
|
Damn, your close!!! Keep at it, you'll get in the 9's.
|
Once you hit the nines it will seem easy!
When the trannie gets in there you shouldnt be dropping boost in secound gear. Good runs glad someone posted something after last weeks excitement! Go Ernie!:icon_tup: |
No breakages right?
Are you using the stock trans or the g-force? What size/type tire? Awesome job though. 10.04 is so close to 9's a slight wind at your tail could have got you there! |
Stock tranny. 26x10.5x15 et streets. Im gonna by 26x11.5's. I think that will also help. Thanks for the encouragement. And no nothing broke, knock on wood. :D
|
Maybe a "softer" compound? I got some ET drags, L8 compound at the shop and boy those suckers are sticky!
|
9s is cake, your just doing it with the wrong combo :lol: :lol: :lol:
J/K J/K, my hat goes off to you for your persistence!!! Good luck to you. The car sounds great!!! Do you have some kind of way to launch at a lower boost, you are overpowering the tires badly! |

I am just still amazed at what Ray has done with the car Ernie. You are getting much more consistant with your times. And at least you did not break anything. And Cecil Co. Dragstrip is such crap, I am surprised you got those times!
Keep it up, those 9's are right around the corner! |
tru dat ernie !!!!!! took the car out last night for sum testing also, long story short got my best 60 ft 1.44 !!! but was a pain in the ASS to drive due to the "clutch setup" ended w/ 10.69 @ 125 missing 4 th gear :wallbash: I got all kinds of issues ............... need a ball bering turbo, or spray da bitch !!!!!! anyways great job on your setup !!!!!!! keep it up " "we" will be there soon.............................................. ..................:scratch:

Thanks Lee, I sure hope so! lol.. |
Wow,don't know much of suspension tuning at all. but the dynamics of it is what Im trying to learn better, and understand. The car looks (sounds) like a monster the power is there but as posted above, there momentum of your car between shifts is the problem.Is it crazy for me to say low nines, and w/ the power ^^ to maybe skate off an 8 sec. with further tuning to suspension???? Is that reasonable to say? That through a well set-up susp. will be able to cut up times like that? Anyways much props to you for dedication,time, and money spent on the sport.
|
congrats
looks like 9's the next time you hit the track. |
good runs Ernie, you'll get there just takes trial and error....
I tried with drag radials friday night and seems I need to do a longer slower burnout 1.9 60' and then broke something clutch wise...... |
Congrats Ernie, you are consistent! Thanks for the updates and glad to see you are getting a lot of seat time. You must have been anxiouss looking at each slip before you actually knew what you ran lol !

Almost there.........
Your 9 sec pass will happen as soon as you take care of your 1st gear drama. You're overpowering your tires, hitting the rev limiter instantly and simply making no ground or speed, therefore going into 2nd early and landing too low in engine rpm/powerband. Staying on the rev limiter longer will not help, you're already doing that loosing too much time. Check your logs and see what mph when banging 2nd gear and what is the rev limiter set at (1st gear)? What diff gears are you using? What pressure are you running on the ET streets? You need to lower your power in 1st gear because right now it's useless...you need it to get you up to speed so when you hit second you will be on your powerband and not fall on its face. Try a few runs at lower boost or no anti-lag to get a good 1st gear launch with less drama and see if you pick up mph when going into 2nd gear. I bigger tire should also help, but remember if they also spin on launch then you're back with same dilemna......common with turbo engines.]' Good Luck JD

GODDAMN...... keep it up Ernie, if you could get the slugish launch down, your there...
|
From the video I can see that you have a major problem in 1st-2nd gear, it seems like the car is leaving way too hard, loosing traction then falling off of boost when shifting to 2nd. Try not to use the 2 step anymore and use nitrous instead for a smoother, more consistent and predictable launch. As soon as you launch the car and the clutch is released, hit the nitrous to keep you moving forward so that you don't bog, keeping the turbo spooled and making up distance at the same time. The nitrous will also get rid of the lag in between shifts. Set this all up within in the ECU so you can just floor and forget about it if possible. Start with a 75 shot and go up in increments slowly if need be, due to the size of your turbo you might need more nitrous but start there as a base. This had worked and it's still working for all of the people that I know of using a HUGE turbos in an independent rear suspension type of car using a 10-10.5 inch wide slick that are going single digits. Just my 2cents which aren't much, but I know this from all the of people I've been around import drag racing that have gone single digits with similar setups to yours, just trying to help.

I am ordering the 11.5 et street tomorrow. I found the anti lag comes up 10times faster than when I was using it with the Tec3. Im going to soften the rear, use the wider tires, and get off the antilag sooner and see how it goes. |
AND TAKE THE TIRE PRESSURE DOWN TO 10-11PSI YOU KNUCKLEHEAD :p

^^^^^^
I skeeerrred...:D |
How much does your car weigh Ernie?

I personally know that AEM 1800 box can run TC and have done it. It feels slower but I use it as an aid to get out of 1st gear. |

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? http://www.mickeythompsontires.com/tech.php?bulletin=s3 |

http://www.mickeythompsontires.com/tech.php?bulletin=s3 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. |

This is from the proper suspension setup thread. 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? JD |
Congrats Ernie, you sure are one persistant mofo. I top my hat off to you, i'm glad you haven't given up. You're bound to hit those single digit E.T's soon!!!

CONGRATS Enie!
Once you sort out the bugs, not only you will run a single digit pass, but it will be an IMPERSIVE one too :icon_tup: |
beautiful runs the 9's r right there,,,hopefuffuly u get everything adjusted so u get what ur looking for,,,good luck
|
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! |

just take off in 2nd gear. barring any breakage, you'll hit your 9 instantly.

Seriously is that an option? :scratch: 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! :) |

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.
Im ordering the slicks. |
Awesome, I think in your case, slicks will make a tremendous difference.
Not to get off topic, but i was reading your sig. What is the IRS RX-7 Record? |
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!! |
I remember the street class days... which car did you have that came in at 2800lbs???
