Stutterbox Pros and Cons

[Goobdog]

Can we use the MSD 2 Step box by itself in our cars ? Or do we have to use the DIS-2 box ? Only reason I ask is because my dad has one in the garage from when he used to drag race and he said I could have it if I can figure out how to hook it up in my car.

 

[NDgsx]

It has to be a DIS (Distributorless Ignition System), either the 2 or 4 will work.

I use a MSD DIS 2, it has made my times became very consistent. If there isn't knock or a missed shift they are normally within .020 of each other. I also wired mine up to the upper clutch switch (ac), so that as soon as I start to disengage the clutch the RPMs are cut. That way I can shift without lifting off the throtle, which dropped two tenths off my average time by itself. Now if I could just get the car to hookup with the 2.4 now....

I can get pretty consistent sixty foot all day (within .02) w/o studder box and on shitty Kumos/3bolt rear). I ran 1.675 but mostly 1.71 with 712s and stock 170k miles tranny.

You do not need the studder box to run consistent sixty-foot. For guys that can't get decent sixty foot, launching with studder box will only asking for troubles (broken part that is). Learn to launch correctly first, then jump onto studder box. Once you learned and master the slip/dump technics, launching with studder box will yield satisfactory sixty foot (mid 1.6s)

Studder box is either for guys that already master their launch technics or for guys that only want to look cool.

What would be the cheapest 2 step for my 2g with a 6 bolt? I really don't have the money yet for DSM link, and cant keep my 60' even, they range from 2.1 to 1.8...

I'm not sure about the MSD box but a Keydiver chip would be ideal for you. I think Jeff has finished the adjustable stutter for 2G's. Being as you are a 95 anyway you should have an EPROM, that way you will already be socketed for DSMlink when you finally realize how much tuning with anything else sucks. www.dsmchips.com

 

[BGRIPTP]

Thanks, and yes I do have Eprom. I will look into keydriver.

I'm probably wrong but it seems to me that a stutterbox would put a ton of stress on the drivetrain.

No more than launching at 5k free revving. All it does it hold the RPM steady so you have less to worry about. You just need to learn how to launch, the best method for not exploding drivetrain parts is to abuse the clutch a little by slipping. I don't know about you but I'd rather replace a clutch than rebuild a tranny.

Where you been hiding Mang. Need to get a runnin dsm out there!

Ya I bought Travis's silver fwd. Just got a n/t engine and tore it all down to the block. Need to pressure wash it and hone it. Should be running pretty soon. O ya, this is a but off topic but, I have to say this. I got the record for NFS Underground 2. Took the 240 with all stage 3, changed some settings and ran a 6.98 in the 1/4 . Ryan's best is 7.04. He's pissed. I guess Jason was doin 7.30's all day and he "had" the record . Peace Pru Doggy Dizzle!!

 

[DSM007]

the only con I could think of is it kills your clutch?

killed mine

I use an MSD DIS2 as well for a two step at 5500rpm and it works awesome. I use about 65% throttle while holding it then floor it just as I leave the line. Too much more than 1-2psi of boost and it spinns all the way though 1st which makes my 60ft times worse.

you must be a clutch dumper. i havent raced my car at the track yet since ive had the studderbox, but i have had a couple street races, well abondaned industrial park races (shh). and at a 5500 rpm studder with foot to the floor building about 7-8 psi i would let off a loud chirp but the car would rip outta the hole. next to zero spin. i used to pull pretty damn cionsisten 1.7xx 60 ft.'s at the track last season and ill tell you they definelty felt the same if not a tad better. its all in the slip of the clutch.

I might not be a clutch dumper, thanks for the tip however, I leave with much less boost than you do (easier on trans) and pull just as fast a 60ft and a faster 1/4 mile than you do, on stock cam's I might add.

BTW based on your timeslip going 8.0 @ 87mph in the 1/8th it seems like you need some help shifting

you are exactly right, i do need help shifting, its called a new tranny. second gear is a bear to get in, and third gear grinds every time when racing

oh and about the 12.5, thats old news i have done alot since then suprisingly, just waiting for the track to open. butt dyno tells me low low 12's possibly an 11. but im not gonna be a bench racer here. all i have to say is im shooting for 11's next racing season. oh and lets not forget that time was on an internally gated 50 trim with just an afc and logger to tune. stock 2g intake mani also

forgive me for rambling, its new years day and i just woke up and im still a lil drunk

Just curoius... But most people replying to this are AWD... so... as FWD, I'm gonna ask it... Will a studderbox help me out? and what would your recomondations be for setting it at?

Don't you guys already have traction problems lauching without boost?!?!?

 

[TurboStutr]

if you have full traction(slicks), then a stutter box would help...but FWD on street tires would just roast 'em all through 1st...not good

 

[DSMJim]

roast 'em all through 1st...not good

and 2nd...

When I raced my FWD I really wanted a stutterbox so I could keep the revs low enough. I always got too excited when the starting light was counting down, I'd give it too much throttle and smoke the tires. It depends on your turbo, but I would try setting it around 2500 rpm so you don't build boost and don't have too much power. I'm sure it would help you control the wheelspin and improve consistency.

Those w/ the TMO where have you wired in for the clutch? Top or bottom. w/o researching the top switch it came to me that althogh my clutch engages very near the floor once the switch is no longer engaged it will free rev. So has anyone had a problem with this or is it so simultaneous its not noticeable? Im not sure what advantage the top would have but for that instant that it could free rev it might get scary. I have not made it to the track yet but I want a mid to low 12 and trying to keep the motor together for 1 good pass. Any thoughts guys. Thanks P

I love my 2 step but i have the exact same problems as you Lowridin, My tranny was Rebuilt from Shephard not but 4 months ago. And i can cut 1.60 60fts but getting into 2nd gear is Almost impossible when i use the Studder box... It doesnt grind at all it just sorta locks me out for little bit... It shifts like butter while daily driving and doesnt grind in any gear... Does anyone have any insight on why the studder box launches make it hard for Us to get into 2nd gear????? This is a serious problem because it cause my ET's to be slower... best time so far @ 19 psi is a 12.5 @ 112mph with a 1.60 60ft...

The bottom switch works fine for me. Just make sure you push the clutch in/out quickly when you shift. There's nothing wrong with a split second of free reving. When I launch the car on the stutterbox the revs will climb a few hunderd rpm before the clutch engages, so I adjusted the stutterbox rpms slightly lower to compensate. Even if you hit the rev limiter it's no problem, it's just like hitting a 7500 rpm stutterbox.

How's your motor mounts?

That's a nice 60' time, those stutterbox launches can be wonderfully explosive off the line. Without some prothane mounts the motor will jerk forward during the 1-2 shift and tug on the shift cables. HTH

 

[Froyd79]

Thanks for the info! Not only is it good to get another side of it ( which gave me some new ideas) but my motor mounts are tired too. So That helped 10 fold thanks buddy!

Wow ive been stumped forever trying to figure this out... You know something, I think you hit it dead on the spot.. My motor mounts are the only thing that i havent replaced on my car!!! go figure... hell even when im sitting still and free rev the motor from under the hood i can see my whole motor shift back and fourth.... They are very worn theve been on the car for 140K so i think ill order some here soon... Thanks alot

The most common methods of aquiring a stutter box are DSMlink, a chip (TMO, DSMchips, etc), or an ignition box (like the MSD one pyro mentioned). The ignition box method is the only one that doesnt require the purchase and install of an EPROM ECU (one that allows you to change the chip). It did wonders for launching consistency, and it helps to spool the turbo as well to lower the 60 foot time a bit. Not much risk if you are not dumping the clutch like an assclown.

will the dis2, 2step work with the auto version of the 2g gsx? had anybody used it before on an auto?
