390 rwhp WS6 dissapointing 12.8@111
02 ws6 m6 with 125k miles
Current power mods:
222/226 cam
BBK LT headers with hf cats
Lid
Catback
I did the cam/ header swap around 95k miles. Did the LS7 clutch a few months ago
Had it retuned and it put down 390/365 SAE corrected.
My best run after about 25 passes is 12.8 @ 111 with a 1.9 60 ft.
Is something wrong with my car or maybe a happy dyno???

It's called heavy *** car + M6 transmission + Incorrect tire + not enough Launch RPM = Sub optimal MPH and ET.
So now you need to invest in a rear end, gearing and suspension as well as a drag rim/tire package. Maybe a 2 step and go back. That should be by the time your done with your own labor 3-4 grand. Maybe more depending on parts and what work you dont do.
I can tell you I may like 5-10 rwhp less and managed a 12.3 @ 113 and that considered not even good. I Am very heavy and the car heavy as well , only weight reduction we a fiber glass hood (stock t/a steel to WS.9 Fiberglass), and took the rear seats out. BMR LCA w/ Relocations, BMR TQ arm, Moser 12 bolt 4.10's on Convo Pro's and M/T ET Drags (26" tall small *** slicks).
The car hit so hard that the body bounced off the rear and did the 3 wheel gangsta so long story short, I need to go back but not until I did SFC's Drag bar in the rear, and shocks. ALso weight reduction and maybe more gearing (4.30's or more.
Gearing and the proper tire/rpm speed is going to make a huge difference and may put you in an 11's so as long as you can drive.

The car cought bout 1.5 ft on the left and 1 ft on the front. Nice pop but getting stiffer shocks to control is what is needed. I have 10 Way QA1 which is probably not enough but gotta work in the budget....

not being an *** but the DRIVER MOD would be your best mod.... get more time in launching the car and get those shifts quicker.
I've seen multiple bolt-on 6 speed cars run 12.3s-12.4s with no suspension and the stock rear end.

drag wheel & tires=$1500-$2k
2 step=$200
Some suspension stuff like crossmember mounted torque arm, PHB, LCAs & SFCs= $1k. Then if you want drag shocks more$$$ on top of that. It adds up quick.

on the stock 10 bolt. 1.9 60s but didnt break.

I forgot to mention my car is lowered with a koni shocks/strano spring combo. I do have subframes and adjustable LCAs set for the best angle for drag racing.
I am also running on nitto 555r drag radials set at 18 psi when im at the track. Is 1.7xx gonna be the best 60 ft with my power level/ tire?
One of the rear KONIS adjustable **** is stuck on full stiff and they are sending me a new one.
Would it be ideal to set the rear shocks to full soft???
I have a feeling being lowered is hurting me.
What i fail to understand is the mph of 111??? Thats why im thinking its a happy dynojet. Im running at Sacramento Raceway, i dont think the DA is that horrible.
Thank you all for the input so far.

Don't feel too bad. My best in my cam only 2000 SS (heavy car with leather, no weight reduction and aftermarket ZR1 rims) was a 12.8 @ 113 on Sumitomo's. My car put down 387/384. Other cars on the same dyno ran about what the numbers said as well.
I was disappointed in the car, but sold it before I could install 4.10's and get a decent tire out back. I do know that car did well against others from a roll, so the power had to be there. I just lacked getting the car out of the hole at the track without spinning too much. Plus the DA wasn't the greatest when I ran.
I am willing to bet your car has more in it.

Just throwing it out there, when you add a cam almost all DR cars turn into a "on/off" switch when it comes to launching at the track. Stock cars (with bolt ons) can get away with a drag radial since they dont make any real power. But add a cam and a tune and its a different story.

DA has nothing do to with how suspension works, if anything the power it will not make will only help the situation. Take a car that can barely get off the line in 5000 da and throw same car on same track with -2000 and it likely will just be worse.
M6 cars, as a general statement never live up to the expectation when it comes to drag strip performance. You can spend ALOT of money, putting a bulletproof driveline and the best suspension under it but the trans, the non existant ability to be consistant and the fact that you will be breaking them, whether it be going thru clutches, breaking the trans, or some other driveline part are just a lost cause.
If, you want to drag race with a stick car, a gforce or liberty trans, and a slipper style clutch is the only way to go. Be ready to spend some money, and you won't be driving it on the street with said clutch, as that will eat it up FAST.
Is what it is, that's the truth of it. Accept it, and live with what the car's doing, or spend the money to change it. Really the only options.

I get that about building up for the track for optimal results.
A guy i know has an 01 m6 ws6 with headers and boltons untuned and he traps 112 and has gone a best of 12.4 witha 60 ft of 1.8 i believe.

While i do agree with the above statement somewhat, i think you are failing to understand that he isnt looking to break into the 10s or anything like that. He is looking for low 12s or a high 11. And yes there are PLENTY of 6 speed cars running those times. And some even in the tens. This is WITHOUT spending thousands on a transmission. Just need to buy a better clutch. His car does have the ability to run great times without switching to an auto trans. Im sure that he enjoys driving his car on the streets just like many others.

And there's nothing wrong with driving it on the street and enjoying it.. that's what the cars are meant for.
BUt, if you want a time slip, you have to drive it like you hate it, stole it and don't care about it. Just powershifting the car will up the mph into the 115 mph range I'd bet.

But, 125K on a stock tranny, kiss it goodbye. It's going to break. Don't be fooled..... most if not all the cars you see that are running the #'s that you are aiming for, are driving the cars in a way that is going to do damage. 10 bolt, it's done for sure driving it like you have to in order to get the timeslips you're after. Those fail at stock power with any kind of tire on it. put 390 rw to it and it's 100% done.
Transmissions won't like it either.. power shifting the car is going to really put a beating on the driveline... I'd guess that one power shifted 1/4 mile pass is like 10 thousland miles of driving normally.
OP, drive it like you are trying to break it. Leave at 5000 rpm, ride the clutch out if you have to, you will get that one hail mary pass if that's what your'e after. Just be ready to call a tow truck.

First , get some line lock or let me drive your car with you in the passenger seat to show you how to do a proper foot brake burn out cuz you ask like 10 different people every time your out there " how do I do a burn out ?" Lol
Second , get some tires and a rearend that can hold up better than the 10 bolt and drive it like you stole it!!! Launch thay ****** and shift it at 6700 on your tack to account for human reaction with shifting a six speed.
Your 60 foot and you driving is killing your time.
Third, get a beater to drive everyday and stop putting miles and that nice bird. Will allow you drive it like you stole it and not have to worry about how you will get to work the next morning
you know where to find me if you need more of the same advice hahaha
