Damn. That's good. You have any vids by chance?

[AWD_THIS]

No vids of that run. We had an all day track rental and there was not enough people for video taking. I will be posting pics and the vids that we did get of that day soon.

[evil_2]

sweet time man..

man, a 10th off that 60 foot and youll be in the 10's

[AWD_THIS]

Here are some videos.

The funny thing is that the car was running like crap dont know why and I am good for hitting low 1.7's all the time. My best 60' was 1.68 boy did I wish I hit that one again.

[hassviper]

oh wow that's amazing, stock suspension too? that saying a lot about your driving

[AWD_THIS]

I wasnt that good at driving before this year but track time and the help of my sponsor and mnay other friends I got better. I wont accept 1.75+ 60' next year.

[slow4dr]

:thumb: Congrats! It's frustrating as hell slowing at the 60ft but gaining ET.




One thing I noticed is you only picked up 24 mph from 1/8th to 1/4. You should be picking up close to 30 mph out the back door.

[lunchbox660]

on the plus side, i'd like to help you with your stuttering problem. change your spark plug wires and i bet it will go away. that has happened to just about everyone i know at one point in time and we changed the wires ans it immediatley ceased to occur.

[lunchbox660]

also, if you are running all that on stock suspension, you can break 10's by changin out some suspension stuff. i have the full urethane bushing replacement, sways and strut tower bars all around and lowring springs. the strut and sways prolly wont help much, but then again, if your chassis is flexing side to side much, it may. the springs are nice because they help keep the weight more to the front of the car. i know you prolly could care less what a guy who runs 13.1's thinks, but i run 13.1's on street tires with less than 300 hp consistently. anyway, yeah....suspension work should def be next on your list.

if you live in socal, i can help you with your suspension work, id love to take a ride in your car!

oh, also, have you stripped the car out? im sure you have, but if not, thats another great way to help your launch and trap speed...

[sota]

That's not the best part.

Tell 'em how many runs you got in :D

[lunchbox660]

lol, well yea with a track rental i can imagine it was prolly ALOT of runs....the most ive ever run was close to 20 runs in one night at perris speedway and i showed up late and left early....if i wouldve been there the whole nite i bet i couldve got over 20 runs in a field of over 150 cars...

[sota]

Yea... and what really gets me is the guys didn't TELL anyone until like the day before practically! :yikes:

I knew I shoulda just said fuckit to all of monday's biz and gone.

fyi... I'm not really mad. but the next time you guys rent the track out, LET ME KNOW AHEAD OF TIME!

[lunchbox660]

lol....thats the way it goes...nobody ever tells me about the track rentals either....ive missed every single one. theres another one coming up soon that i found out about thru the forums, so hopefully i can make that one.

I got in 15 runs before breaking. I have energy suspension bushings. I will be swapping stock suspension for next year. I do have strut towers front and back. I am full interior no weight reduction. Its going to be scary when I finish Project IV for next season.

speak to Jay on that one. sorry man.

[StreetRaceGN]

I've seen this car go 11.5x on a street night at e-town with less than ideal weather. Atco track rentals have good prep, and the weather lately has been pretty good for racing, I can see a 10 sec slip coming soon. If you're interested I'll let you know the next time we have a couple open spots at a rental. We usually try to keep the 12 second and slower junk out of our rentals, so you won't be waiting forever to make a pass and pretty much every car there will be on a tire.

[lunchbox660]

well, i dunno where atco even is, so i assume it is not even near me, and i dont run slicks, so i am still in the high 12/low 13 area, which means i wouldnt be invited to your party...lol

AWDTHIS, you said it was on stock suspension...lol....the engine mounts and bushings are what makes the biggest difference with the launch....lol...swapping to some adjustable coilovers will definitely give the advantage, but the cost is retarded considering that bushings and sway bars alone provide the same performance nearly in almost every aspect other then drag racing...ive never even seen anyone use aftermarket coilovers with a truuly FAST srt4, so i cant speak from experience or visuals. im tellin you bro, strip that beast out and youll be amazed the difference. the rear seat and front seat together are easliy good for nearly 80 pounds combined, the carpet, sound deadening and panels all make up another EASY 20 pounds combined, tire and tools and gas make up another 50-80 pounds depending on how much gas you use/dont use. it is totally feasible to strip about 200 pounds out of one of these cars for a track event and still be able to put it all back in and drive it around the rest of the week. i have gotten so good at it that i can do it in under an hour, go race, and have my car all back together before i go to bed when i get home....

anoteher cheap, easy, but effective way you can afford some extra traction would be to block your rear springs. jack the vehicle up a little bit, stick spring blocks in there and lower it down. this will put the ass end up in the air more, give the front end more rake and put more weigth on the front for better traction. of course, there is a fine line for going too much. get the front end too low and it wont do very well on the top end of the track....

ive done all the cheap stuff to my car that i can to get the numbers i have. i dont need big power or anything. the first time i ran a 13.1 was when the car was still making UNDER 250 hp....since then i still havent broken into the 12's cus traction is limited with street tires, but ive seen my tap speeds increase from 104 to 110 over the past year with the addition of a little more boost and nothign else really. i have quite a few mods, but none of them are really big power adders, just complements to the other little things i have....im confident that if i can get a new clutch and some slicks i can put this car in the low 12's, and with a little more power im sure high 11's wouldtn be too much to ask.

with a car setup like youve got, why are you just now coming around to posting? i mean, welcome to the forums, but dang! where the heck you been? lol....almost into the 10's and just now introducing yourself....lol

nice to meet you!

I hear what you saying. My car is one of the shop cars and we are running numbers with interior. My car is a street driven srt so dont want anyone thinking we are removing anything to hit a number. As for suspension we will be running coil overs.

Thanks for the props. I have been around for a while now just not this forum ( screen name on srtforums REDLINER ) This set up was completed in september of 06 so from that time till now we had tunning and driver mod to correct. We will hit the 10 early next season and all without nitrous.

[lunchbox660]

sweet!

just for the record, my car is daily street driven too, but i still have the gutted interior...lol its fun raping camaros and stangs with less than 300 hp....every jag off with a flowmaster system on their V8 thinks theyre sooooo fast....lol

[AWD_THIS]

lmao :thumb:

[MChat]

Good numbers.

I agree with your decision to go with coil-overs; that's the direction I went. I went with Mopar Stage 3R's (the dual adjustable ones) with 350lb springs in the rear and 450lb springs in the front. I also use the "helper springs" which really help keep the ride bearable on the street (actually the ride is quite nice on the street).

I only got one pass in with the S3R's before I blew the engine, but the 60' was really good and the suspension didn't allow the car to "flop around" like the stock suspension. I set the compression damping to the hardest setting (well one click from the hardest) and the rebound damping to the softest in the front; in the rear I did the opposite (soft compression, stiff rebound).

Here's a post I made on "the other site" over a year ago:

So there are a number of cars out there putting down the HP for a high 10 second (or even lower) 1/4 mile pass, the problem is traction. Even with 26x8" slicks 1.8 60's seem to be the lowest we can manage.

Here's an article that does a good job of explaining WHAT we need to do, the question is HOW do we go about doing it:

http://www.overboost.com/story.asp?id=1319

So here's the main items from the article:

Get Your Car Stiff
The article talks about increasing the rear spring rate to help keep weight transfer to a minimum. The problem is, most of us (I'm assuming) want to keep their cars streetable... swapping out coil-over springs at the track isn't a viable option, so what can we do to stiffen up the rear at the track only?

Here's a couple of pictures of something I came up with, but didn't work. Yes, it make the car stiff, but without the dampening control needed to keep the car from hopping around. Which, once the front tires lost traction, is exactly what the car did:

http://www.azchatfield.net/miscpics/_private/RearSusp1.jpg
http://www.azchatfield.net/miscpics/_private/RearSusp2.jpg

The polyurethane was just too stiff. The concept may work, if instead of polyurethane, I can figure out some way of adding a bolt on helper spring that could be installed easily at the track and then removed to go back out on the street.

Another idea may be to use straps to preload the rear suspension, effectively making it a bit stiffer. Or perhaps some of those rubber spring inserts designed to give "new life" to old worn out coil springs.


Shocks Have Valves Too
Here the article talks about needing have the correct Compression and Rebound dampening. Most aftermarket coil-overs control both compression and rebound dampening together. What we need is a list of coil-overs that will allow us to control compression and rebound separately. Anyone know of coil-overs available for the SRT-4 that allow sepaparate control over the compression and rebound?

Also, some of us may already have coil-overs, which adjust both compression and rebound together. If this is the case, which way should they be adjusted front and rear? Stiff as possible in the rear and soft as possible in the front? The other way around? Something in the middle?


Baby's Got Back Doesn't Help in FWD Drag Racing
Next the article speaks to weight distribution. For street cars there isn't alot we can do. Make sure the trunk is empty, maybe pull out the rear seats. Every pound you can take out from behind the driver's seat increases the weight distribution on the front wheels.

The more adventurous of us may do things like remove the rear exhaust section (either permanently w/ a side exit, or only at the track). Maybe cut the steel floor out under the rear seat & where the spare tire depression is and replace it with .035" sheet aluminum. This mod would only be visible in the trunk and when the rear seat was pulled out.


Flex Your Way to Traction
The idea here is to remove as much flex in the rear suspension as possible. About the only thing we can do without too much modification is to add Polyurethane bushings.

For anyone that's done this, it's a PITA because all of the manufacturers require you to re-use the metal "cups" that house the stock bushings, unfortunately the stock bushings are molded into place. So cleaning these cups out so that the polyurethane ones fit is a chore. The best way seems to be to pry out most of the rubber bushing then use a torch to "burn out" all of the remaining rubber... a very smoky process. If anyone has a better way, please speak up!


Point Your Toes Out
Lastly, the article speakes to Tire Alignment. While a slight tow-out for the front tires is recommended in the article, I would not recommend this for a street car, unless you are comfortable driving it like that. With a slight tow-out, the car will be more apt to wander and it will affect the cornering characteristics of the car. Even if you are comfortable with it, think of anyone that you *might* loan your car to.

Other things can be done with the front end though, particularly if you don't autocross the car. The camber can be set to near 0 which will keep the tires flat to the ground, rather than slightly tilted.


So what are your thoughts and ideas. What have you tried and how did it work out? What are some other things we may think about? Anyone else have any "traction tips"?

[punkrokdood]

awesome post Mike... i'll be trying some of this stuff in the not too distant future. i have just about everything a suspension can have on this car, but there is ALWAYS room for improvement. :thumb:

[psi chick]

if you can't pull better than a 1.8 on slicks you've got bigger problems than a set of coilovers

and vic you're still slow

[punkrokdood]

problems like 491hp, and stock suspension? :lol:

[psi chick]

no more like you're the suck at driving then and should learn how to launch before putting 491hp out

[MChat]

At the time I wrote that almost nobody had ran a sub 1.8 60'.

Another thing is the clutch. Originally I had the centerforce clutch, which I finally figured out was slipping on the launch. When I changed to the CM FX700, my 60' times immediately dropped into the 1.7's.

My best 60' was a mid 1.7, on the stock suspension, with crappy, balling-up Hoosier 26x8" slicks. My goal with the coilovers was to get into the 1.6's.

Now I'll have an autotrans, a decent suspension and 26x10 M&H slicks (the M&H slicks seem to work MUCH better than the Hoosiers) I certainly hope I'll manage better than a 1.8 60' ;)

whats that awful squealing noise like a bad belt? and you need some susp. work.
