How many of you are trapping over 120? What is your setup and how much weight reduction is done? I've taken out the rear seats, seat belts, cd changer, jack/tire, and a few other small things. I am looking to go deep into the 11s. Hoping for 11.00 - 11.40. Previous times in sig is with a 10 bolt and slipping the clutch.

I will be ordering a 9" on Monday so I will be able to actually launch the car. 4.11s w/ spool. How are you guys launching the car as well? Rev it up to where you make the most torque or just high enough to where you don't bog down.

My suspension setup is in my sig. I will not have the money this year to buy a different shock\spring setup.

Any kind of input is appreciated.

 

Get a bias ply, put it on the limiter and let er go.

 

Agreed, you gotta have the will and desire to let it fly off the limiter.

Also you should be looking into adj. shocks as the car will try to xfer weight back to the nose.

 

I've run 11.23@122 with a 1.53 60'. I'm running a Speed Inc SI5 cam with full UMI front and rear suspension, built 6spd, McLeod RST twindisk, 9" rear w/4.30s, and some weight reduction. I haven't weighed the car yet but I would imagine it weight around 3300-3400 last year with me in it.

 

Iv had better luck with radials vs bias plys. My 60fts are A LOT better with the bias plys but I cant keep the car from bogging and slowing my ET Down. Iv been low 1.6s all day but Im still searching for the perfect air pressure to run in the tires. My best on radials was 11.71 at 118 and bias plys were 11.80 at 115 with a 1.62 60ft. Now I havent run in cool air also, with the bias plys the air has sucked and been well over 85 even at night with HIGH humidity! Fall temps and air will be exiting for me!

Iv been leaving off the 2 step at 6500 with bias plys. Side Stepping it and letting it go! Im thinking 6800 is what it needs with the tire pressure. Its a challenge and I like it. Im only 21 and learning every track pass! Mine is full weight as you can get, only thing missing is spare tire/jack. Shes 3620 with me all day! I run mid high 11s and then I can drive it home with the AC blowing nice and cold!

 

What exactly is a 2 step? I'm 21 as well and have been to the track just a handful of times. I have only slipped the clutch on my launches. Well, I take that back... I launched at 4500 without slipping it and twisted an axle in half. Once the 9" comes in i'll be heading back to launch this thing. I'm ordering a pst 3.5 chromoly drive shaft so I won't break that either.

This might be a dumb question but here it goes. Does slipping the clutch and coming out easy to not blow up the rear end and getting 1.98-2.2 60' times make your trap speed any lower? I say that because my best trap speed is 116 and most of you guys have 118-123 or so. I've been thinking about possible switching cams. But I will see how it goes at the track. I have a custom cam from Pat G. It was made for a 100 shot to be used with. Not sure how much I am losing because of that. I've been thinking about the StreetSweeper. A lot of people make good power with it.

 

A 2 step is basically a self controlled rev-limiter. A few companies make then, I have the Lengthfilter. MSD makes them also. Its a box that you can set, adjust whatever RPMs you want to leave at. There are a few ways to wire one into your car. It picks up signal from you factory clutch switch, so when you push the clutch to the floor, it activates. Then you would push the gas pedal to the floor and its going to blounce off of your set RPM just like your normal Rev Limiter. Its very very cool to have and when I was on Radials it make my car deadly conistant! No watching the tack just dumping the clutch and going!

Heres a vid to show you what it does!

You can make all the power you want and it still not do you any good. My cam is the MS4, Great Dyno Numbers but has NOTHING down low. Dyno numbers..thats all I feel this cam is good for. Get your rear and then leave off the limiter and see what happens!!

 

That's the plan. The 2 step is cool but I'm gonna hold off on it for a little bit. I think I'm gonna have to move my seat up so when I dump the clutch my foot doesn't back off the gas pedal.

My cam is awesome under the curve. I shift normally around 6300-6500. It's just a 226/232.

 

you will need 4.56 gear and a 2 step. And get the weight out of the car front rear bumpers and all little things. Pm me i am close and can help Alot

Ive trapped as high as 122 but have been having problems with the car launching, hoping to be around 123-124 once I get everything figured out. Cam only setup of course around 3200-3300 lb. with me in it.

 

another cam only setup in chicago crazy

 

Yep 01 stock long block,SI5 cam and full bolt ons. Hoping to squeeze a little more out of it with a 100mm tsp maf=ftp 104 lid and EWP.

 

I like some of the guys on here are on the right track. The more you look into the faster cam only cars, the 6sp for sure. The more same parts you see, and you don't have to have top $$ stuff.


I get sick is the PM "I want to go 10's cam only" .....I have 420whp XXX big dick cam + full bolt ons. Fully adjustable shocks, and so-so "street/strip" heavy suspention parts. Here is vid, (1st vid in search)
http://www.youtube.com/watch?v=bPxmvWD1Tvc
what do I do with the shocks, and tire psi. it spins or it bogs........
PS-But must keep 3:73 gears 26" et streets. Its a street car and my friends, brothers, neightors uncle said thats the best gear for a street/strip car, he has a 71 chevelle
PPS- I'm scard to launch over 5K



Good luck, but guess what the 1.6s are not gona do it. And you not going to "dail it in" and crack off some low 1.5s 1.4's on thosue tires and gears. Even with the 120 traps. high 11's all day, even in the fall air. sorry no 10's cam only. Put some more gear and tires on the car, then work on setting the car up to use them and the 60's can get a lot better. And it makes it even more streetable with a 6speed.

The big cam factor, with some 27-28 tall street tires, 4:30-4:56 drives smoother, cruises better, less clutch chatter, less surging. lots of little things.



Sence you got 4:11s your gona what to run a 26 slick tire NA. you should get some shocks too, over stocks, and rear swaybar. But you can do it cheap, and works great. This is what I have, super buget. 1.43 best track wheels, 1.57 on stock z28 rims and DRs

front-
$149 strange singles on the front with stock coils, upper moutns, and spring cups modded to work, posted that in my build thread. BMR front Kemeber, No front swaybar, bumper brace,washer,other free mods. Stock brakes,spindles,upper/lower arms s

summit 3 way rear shocks @ 50/50 (free with trade for stock fronts) But there like $25 the pair new and work great. Stock coils cut 1.5 (car is light) no insolater, no bumpstops, BFH mod to wheel wells. PHR brace removed, S60 spool 4:30s, adj. LCA, and PHR, sphon 1inch stock style rear swaybar. wolfe point 4130, no SFC. used RT TA (full lenght, cracked I welded and braced) BMR trans Xover with TA mount. (great all around mod. driving, and shifting)

 

^^ This guy knows his stuff..

I know a Silver SS thats on here a lot that has a little under the curve Cam and hes car runs good. Him and I would go back and forth about our set ups but his car runs great and he has factory shocks!! Hes not a 10second beast but it does run. We have very similar times and totally different cars.

I really need to loss some weight in my car to go any faster. Iv got about 30 track passes on my car (most on radials) and Im still searching for a good 60ft. Im stil searching for the right tire pressure and Rpms! My best ET todate is on Radials with a 1.77 60ft. Putting ONLY bias plys has dropped it to a 1.62 with just tire change. I have only ran 1/8 mile with these tire..well I made 4 passes at Pinks All Out in 110* air and spinning like crazy on a hot track. But 1/8 mile I have droped almost .2 tenths from just the Bias Ply. Radials were more fun and felt better top end but to get the ET..Bias Plys the way you got to go!

It takes time,a good track, and adj. 1 thing at a time. You cant make a pass, bog like crazy from a 6200 launch with 14lbs of air in the tire, come back up tire pressure to 15, launch at 6700 and change front and rear shocks. One thing at a time. Every pass I make on the back of my slip, I right what my front/rear shocks were set on, tire psi, and launch RPM. See what worked and what doesnt.

I would rethink your 4:11 gear..I can daily drive mine with 4:56s and a 28in tire down the highway at 70+ MPH. When I had 4:11s with a 315/35/17 (prob close to a 26in tire) The RPMs driving down the highway and crossing the traps is Almost exactly the same. 4:56s all the way and then cruz with the AC Blowing Ice Cold!!

 

damn you guys have to do alot to get these m6 cars to get down...

stock rear shocks, stock rear springs with isolators(no hose mod)

1.35 60ft 230/230 cam only...

I definitely give the guys who can get down with m6s props

 

I'm pretty dead set on the 4:11s. I honestly don't want to buy new tires. If I buy new tires i'll end up buying 15x10s. Never ends. Just gonna stick with my 15x8 275/50s. What is the best psi to run in the MT radials? 17 or so?

 

we went 10.33 @ 127 with a 1.33 60 on that pass we spun a rod bearing the pass befor we traped 131 but a **** 60 killed the run.... we have something for the record ..

 

^^ The radials wont hold the shock of 6000 Rs..I tryed it and doesnt happen...

M6 takes some practice but once you got it better watch out these things get down.

 

Have fun running 11.40's at best then. i say sell your gear and buy a 4.56 or 4.30 i mean you have a ford nine to swap the gear its cake. And trust me i drive my car every day its nice and once you drive with a 4.56 and 28 tire on the street you will wish you never dicked around with the 4.11.And no matter what tire psi or any of that you try you will bog. the key to a m6 good 60 is a little bit of tire spin. if you cant do that you better off doing a fast slip out of the hole because you will have to rev your motor past 6300 on up to get good wheel spin and speed and also keep it going with out a bog.

This was the best i did with 3.89 gears 26x10x15 slicks and a 2 step set at 6800rpm.I say save your for a gear and tire setup and dont waste any more time and money with the 4.11's Trust Me and stud we have been working at this for some time now we know.
