who uses these? someone on here is telling me if i put primitive limiter straps on my drag suspension 11.7 car then i will be running low 11's like it should be easily capable of.

 

Buy a double adjustable suspension and don't worry about the limit straps.

 

What does your car sixty foot now without the limiter straps?

 

I am the one that said limiters could help his set up. I also suggested running a two stage boost controller, and to try running less than 13 lbs in his slicks. With these changes I told him he could go lower in the 11s. I will let mike fill you in on the timeslip breakdown.

i never said the limiters wouldnt help. what i was saying was they arent the reason why im not cutting lower than 1.9 60 foots.. that has been easily done a million times with no limiter straps. and yes i did agree to run less than 13psi in the slicks. i dont feel the need for a 2 stage boost controller for 400+whp. if you have driven the car you would feel it didnt need it either.

basically here is the setup for 60 foots.

-22x8x13 slicks
-pic performance drag coilover setup
-engine mounts and torque mounts
-full race traction bar
-2step and anti lag

some people say i need to burnout longer but i dont know. i burnout until i see smoke rollin. i do need to drop the psi down to at least 10psi.

and what do you guys think about 60 degree track temps? i know that plays a big role and i do get alot more traction when temps are more like 75 and up.

but its only been the 2nd time to the track for this so i know its going to take more practice.

 

sounds like u already have some good ideas on cutting the 60 down.

Lower PSI and boost control are 2 good starts.

 

Put some 24.5s on that car, you've gotta be spinning the 22s.

that was the next plan after these slicks are finished..

 

13 psi in your slicks. What are you driving on the highway with that much pressure. Lower that.

what do you suggest?

 

7-8 psi

 

6k 2 step
23" slicks with 6.5 PSI
omnipower drag coilovers
2nd gear burnout

equals..... 1.75 60' in an EJ8

this is going to be the #1 thing for you, we really cant tell you what is going to work and what wont work for you. we can give you a good starting point by telling you what we have all done. after that, its practice makes perfect. and you will have to go back to the track with these new idea's and go to town, to figure out how you can drive the car, (with XXXXX settings) to achieve the best possible finish.

i say more seat time, with more seat time comes more knowledge and experiance, it also helps to have a "good hand" at the track with you, so you can consult about what is happening, and how you can try to "fix it"

all that being said,

goodluck + post back with your results. it will pay off.

 

i ran 22's for a bit before i went to 23's....13psi is waaaay to much. i was running 7-8 psi launching at 6200 and pulling consistant 1.72-1.77 in my 2700lb 4dr....

finding the right launch rpm and slick psi will get you the most out of what you have now...i couldnt get into the 1.7's (averaged low 1.8's)at all launching at 6400...lowered it 200 rpm's and the next run went 1.72

set your slicks to 10psi, keep raising your 2step till you spin, then lower your tire pressure till you start hooking again...good luck!

x2 on 7-8 psi

13 psi you might as well be commuting on the freeway with them....

 

24.5 M&H @ 6psi, 7.2k 2-step got me 1.67

 

Limiter straps is not the problem which you already no. Your slicks are too small for the power you’re making but if that’s your only choice then drop the pressure down to 8psi and a second gear burn out and you should see a world of a difference.

I was thinking the same.. 24.5x8.5x13

 

How many of you have used limiter straps?
From personal experience I have tried no limiters at the track for two passes then put them on for two passes. My first two passes without limiters were 11.0 and a 10.9 with a mid 1.8 60ft. My next two passes with limiters were 10.6 and 10.7 with a low 1.7 60ft. I made no changes to the car at all and the track conditions remained unchanged.
Limiters are not going to be a miracle fix for you but they dont cost much and I qurantee they wont hurt performance. Just my .02 cents.

If he his having trouble staying in boost between gears with his current set up then 24.5s will not help with the rest of the track.

24.5x9x13 5.9-6.3 psi 1.55-1.57 in testing at palmdale,ca without straps.

if you like to know how its done, and are attending the las vegas nationals july 13-14 stop by the nhra urbanracer sportsman alley ill be glad to show you how its done on suspension

 

i used straps several years ago on a car that had a solid rear suspension...once the rear was solid the front started lifting...i strapped it down and had good luck...i was running low 1.7's on a 20x6x14 slick on an all motor d16a1 that was making maybe 120whp. it worked on that car, but i think its a bandaid for proper suspension....

 

I haven't used them but once I was looking into them and I contacted the company that made and they actually stopped making them because they said in their testing they were useless, and there were much better options out there. Search the archives and you should find it.

BUT if people are having good luck with them then give them a try Only after addressing the above issues, of course. I personally feel that if the front is lifting up then run a stiffer rear springrate, or a better option would be to get a coilover setup that let you adjust ride height and preload seperate for even more tweaking

Hell you need to show me how it's done

running drag supsension.. so dont really see how limiter straps will help when the front end is not lifting..

Then you would have no use for them The guys gave some good tips above for some better 60's
