12 Second Club - In the 12s, 3 mods only on M6

I did this two weeks ago, but I forgot to post. The car has only 3 performance mods which include, QTP Longtubes, TSP Duals, SLP Lid. The car also has a short shifter, 160 thermostat, and all the free mods done to it. The car is tuned as well. The car is full power with T-tops. Only the tools and spare tire were removed.

Car made 352whp\355wtq, tuned on the dyno.

Car was on 245/55/16 street tires lowered to 18psi. Temperature was 86 degrees F. Did a medium slip off the line to minimize wheel spin and nailed every short shift quickly. I made two passes that night. This is the best of the two:

R/T --------- 0.860
60' --------- 1.988
330' -------- 5.466
1/8 --------- 8.350
MPH -------- 86.92
1000' ------- 10.619
1/4 --------- 12.798
MPH -------- 113.92

This was as clean of a run as I could have hoped for. I don't think the car will go faster than this on the general bolt ons with street tires. Maybe mid 12s with drag radials, but that's it.

wow thats a lot of power for those mods....and good runs!

Not really. It's about average for a full bolt on M6 with a tune.

That's a lot more than 3 mods, haha. But a great trap speed. Nice job.

Looks/sounds like your car is damned near identical to mine. Nice run

D

nice!

Get some DR tires, w/ your trap speed you could run mid to low 12's-if the stock clutch and rear hold up.

Nope. Just 3 performance mods. The rest of the mods do nothing for engine performance, and are for the engine reliability or deleted misc. crap from the engine bay.

Rear seems to be good as I am slipping the clutch out to not cause a racket back there. The stock clutch however is starting to get mushy and mildly slips every now and then on a quick shift. Next modifications will be reliability mods (Moser 12 and some sort of aftermarket clutch).

nice runs =)
what rpm ya shifting at?

Very nice runs. I have a few questions if ya don't mind:

-What was the shift RPM, as asked above?
-What was the Track DA at the time of your runs?
-What's the year of your car?

was that on a dynojet? i got 326rwhp and 334 rwtq on a mustang dyno with headers, full exhaust, lid, free mods but no tune.

1. I was shifting right around 5600-5700RPMs. Because I'm on the stock camshaft, most of the power peaks under the RPM range. So there is no need to completely wind out the motor, as the power falls off a bit towards the end. Shifting at 5600-5700RPMs puts you smack back into the beginning part of peaking power band. Also the tachometer reads a bit slow from what I've noticed.

2. Track elevation is 70' above sea level, and the temperature was 86 degrees F. This is in Florida. It's mostly flat around here.

3. My car is a 2001 regular Z28 M6.

Mustang dyno my friend. I was a bit surprised, since I was expecting numbers around your output. A good tune goes along way.

Update, going to the track tonight with a set of drag radials that I'm borrowing from a friend. Assuming the stock clutch holds up, I should put out some impressive times.

Where are you in florida? You go to Moroso (s fl) or Speedworld (orlando)?

Very similar to my car with those same 3 power mods, QTP's/TD's/lid (tuned of course) = 12.87 @ 112 2.0 '60.

Great job man! :thumb:

Edit- We made close to the same power too! I made 355/357 haha, thats awesome!

You need to powershift, it will give you 2.-.3 , made a huge difference for me and with the stock clutch as well and less mods I went 12.6, untuned. ::engarde:

yeah the mph is good , I ran 11.9 at 113mph 1.6 60ft though with auto. So yeah the mph is great

What RPM are you launching at? Also are you power shifting? What tire pressure did you run? Thanks!

Did you read my thread opener?

I am not power shifting. I am, however, shifting very fast.

Update: Well, I went to the track last Thursday and tried my luck with the drag radials. Very first pass the clutch slipped bad on the 1st to 2nd shift, and completely gave out on the 2rd to 3rd shift. I had to let the clutch cool for over 30 minutes before I could drive it without it slipping in gear. I'm going to be getting an aftermarket clutch in, and I'm going to try again with the drag radials when I find time.

I had my clutch slipping really bad when I went to the track my first time. Thought it was done. It was just super hot and holds really well still over 1yr later. Crazy eh?

It's driving okay now, but I think I glazed the disk because it's chattering now. Oh well, I got a good deal on an LS7 clutch kit, it's going in tomorrow. I'm going to break it in going to work and leisure driving before the track this Thursday.

rt 0.8**, does that mean it took u almost a full second to start moving? Does that count towards your quarter mile time?

^ No he could sit at the light for 5 minutes and his time would be the same. Basically the clock only starts when you start moving enough to trip the staging beam.

oh ok makes sense

Do I count as I just dipped into the high 12s with just Longtubes,cutout,3000stall

Oh who am I kidding ive got a few more mods then that:bang:

I ran about the same time with similar mods, 12.80 at 113 on street tires. I just put a new clutch in, Ram Powergrip, with dr's hoping for mid 12's

Nope. Just 3 performance mods. The rest of the mods do nothing for engine performance, and are for the engine reliability or deleted misc. crap from the engine bay.

The short shifter, 160 stat, and "free mods" are all mods done to make the car perform better; therefore they are "performance" mods and it can be argued that all or any of them will help you do better at the track. Therefore, you have more than 3 mods. :D

A tune is not a performance mod? A tune can give you from 10-25 hp over a stock tune. 160 t-stat also a performance mod, lower temp=more hp.

Just th facts ma'am.

I'm talking about engine modifications: those that directly relate to adding more horsepower. The thermostat allows the engine to run at a cooler operating temperature. It however is generally not an engine performance modification. The same is to be said with the free mods and the short shifter. They are to help my drive the car and to remove useless crap from the engine bay.

As far as the standard power making modifications (i.e. I/H/E), those are what I have.

Basically, if you are unhappy with my title thread, just rest assure that it's simply a bolt ons car.

No big deal, I was just letting you know how it's going to be interpreted. It's like people who say the car is bone stock and then you find out they were running Nittos; it's not quite accurate. I think you did well for your mods, all six of them. :D

J/K :)

BTW, what track are you running at?

3 mods, but every 6spd ls1 w/ LT's and true duals should be in the 12's...good runs. not being an ass just saying its pretty common

It's just most people don't know how to shift fast or launch. Most bolt on LS1s down here run high 13s to low 14s. It appears nobody can drive their M6 car down the track properly. I get people asking all the time if I'm running a shot or something on the car. They are in disbelief when it's just bolt ons. Sorry to say, I didn't have the heart to tell them their 2 second granny shifts and or miss shifts don't help their 1/4 mile time.

It's really bad down here actually. I've yet to see a bolt ons M6 LS1 do 12s, other than myself. I mean the all motor Honda guys are whooping up on these guys running low 13s.

On a side note, the LS7 clutch is in and broken in. I'll be going to the track next week on drag radials to run mid to low 12s with just bolt ons....assuming the 10 bolt holds up.

Thats not to bad. What track where you at in florida. I was just at the Orlando speedway this weekend in a white trans am. Wonder if i seen you.. as for the cant launch part lol you said... Thats me Fu-k.

I cant launch as noted by 2.0 60's but still ran 12.6

SuperL, if it'll make you feel any better, I managed a few better passes couple nights ago and again, damned near identical power between us. Where ya at and consider a run? :D

Nice. I'm going to do some prepping tonight (change oil, flush fluids), and get it ready for the track tomorrow. The car is running great. I had the tune tweaked a bit more, to squeeze a bit more power out of my setup. The car has nothing new other than the LS7 clutch. If everything goes well and I drive it like I did last time, this car is going to see mid to low 12s on bolt ons.

good lucky, a buddy here a 12.5 at 115 with boltons+clutch+radials, so its definitely possible

I'm going to do it tonight. Look for updates!

Where are you at?

UPDATE:

I went to the track Thursday with the drag radials and the new clutch, no other changes. First run I missed a gear, which is very uncommon for me. I had high 12 second runs, getting a feel for the drag radials and how hard to launch on the next two runs. Then on the last run of the night.

R/T --------- 0.784
60' --------- 1.688
330' -------- 5.042
1/8 --------- 7.890
MPH -------- 88.97
1000' ------- 10.195
1/4 --------- 12.104
MPH -------- 114.86

Woot! Low 12s on just 3 bolt ons and drag radials! I knew it could be accomplished. The trap speed was there from the last time I ran the car. However, my 10 bolt is starting to make some whining. I think it's time for a replacement before I abuse the car again on drag radials. This is as fast as a full interior, fully loaded, M6 with T-tops will go with just bolt ons, in my opinion, as I drove the fuck out of the car. I nailed all shifts points pretty good with the short shifting and the launch was excellent, in my opinion.

Next week I'm putting in the Moser to replace that crap 10 bolt. Along with it, is going to be a 150 shot. Should be fun!

buh bye ten bolt, hello 10's

buh bye ten bolt, hello 10's

Yup. It's knocking on 11s with just bolt ons as it sits. With the Moser and a 150 shot, 10s are a possibility, but not likely. We'll see, this car is running very strong and the compression is good. It should run very stout on a 150 shot. I installed the Moser and the 150 dry shot yesterday. I have not sprayed yet, as I'm waiting for tuning and nitrous fill-up. I'll be jumping to the 11 second thread next week.

If you do run 10.9 or better :barf:

FANTASTIC RUN!!! Do you remember what rpm you launched at on this run? Also, what gears are you going to put in the Moser, just curious keep up the good work!!

I'm pretty sure it was around 3500-4000rpm range. I wasn't watching the tach, I usually just "feel" the cars traction.

I'm running 4.10s in the Moser now.

On a side note, this Moser feels alot different in the turns.

Super, i saw you on TR. Are you a local? If so lets meet up and run em!

Do you know of any F-body meets around Florida?

where in FL? there are a bunch by me in st pete.

Oh, and btw I am running just a little quicker now from getting a tune and some other small stuff done :D

Nice job..I hope my car responds that well to mods!!!

Good luck man. My car stock was not impressive. I could only get a 13.5@104. It did have crappy tires and stuff, but I'm a good driver and that's the best I could get it stock. You're already running a 13.1, so you should be ahead of the game, but who knows. Maybe my cats or exhaust were clogged or something. There are so many factors that could contribute to average or worse stock times considering my driving. I gained 10mph in the trap and dropped 1.4 seconds from my 1/4 mile time with bolt ons, tuning, and free mods. I would say these cars really wake up when you mod them.

Well, my nitrous is on. :D

I just have to tune the thing. It might be too much Vtec for me.

cheater :nono:

Don't worry. I got the kit for cheap, just to throw it on and try it. It will be disabled when and if I decide to cam this car. However, with the 150 shot, look for me in the 11s forum soon. :D

On a side note, this Moser feels alot different in the turns.
what u mean?

what u mean?

The Moser rear has a different feel to it when you drive it and take it to the turns. It feels more rigid, but like you can't "feel" what the rear end is doing as well as the stock rear. Maybe it's just me, but it feels a bit different than riding with the factory rear. I'm very in tune with my vehicles so I notice things like this.

Did you put a 9" in it?

thanks, im a roadracer much more then a drag racer (did a bit of formula 1600 and 2000 racing), so this is good to know

I find it interesting that you chose an F-body to road race with. These cars are not great handling cars at all. I'm sure you can augment its suspension shortcomings with a nice suspension setup, but this car is just not setup to handle well, in my opinion. When I say it doesn't handle well, I mean the feel of the car just doesn't cut it for me.

If you want to really have fun with an LS1, swap the motor into something light with an independent rear like a 240SX. An RX7 will also do nicely. Or if you want to be insane and eject yourself like a poptart you can put it in a early 90s Miata.

As for the Moser. It's not terrible at all, it just has a different feel to it that you'll have to get used to.
