Malone stage 3

[gotmud]

I got a Malone stage 3 with dynamic egr and idle and pp520 nozzles.
It pulls LIKE MAD ;-)
I get like a shudder i think its the clutch LOL
I want to change the clutch and flywheel. I want to know the difference or benefit from a 21lb to a 17lb flywheel or vis versa.
Thanks for your help guys .

 

[Seatman]

Stick with the 21lbs, it's way better, that with the sachs VR6 clutch kit is superb imo.

 

[gotmud]

Explain the reason for a light flywheel? Or why a 21 in stead of a 17

 

[gotmud]

Oh yea my golf is a TDI

 

[A5INKY]

The strong torque pulses from a TDI coupled with too light a flywheel is no fun. You need the greater flywheel mass to dampen the harmonics. I have a lightweight FW on my well built PD and can't wait to swap it out for something much heavier. I will be doing this soon.

 

[gotmud]

So there is no benefit to a light flywheel!
Why offer them then,,, faster rpm response ?

Zero benefit, only problems. Why are they sold? I'll answer that question with another question: Why are these are still on the market? http://tornadoair.com

Even a mildly built TDI (like yours) will usually out accelerate the available traction in lower gears already, why would anyone want to exacerbate that?

I got talked into the light FW by a vendor years ago before I knew better. Now I have a very powerful car that settles into a retarded 'loping' idle due to insufficient FW mass from time to time. I'm no longer amused or intrigued by the lightened flywheel fantasy of a quicker revving TDI.

Want a quicker car? Go bigger nozzles/turbo/tune.

 

[Seatman]

I think lightened flywheels etc come under that same heading as like k&n filters and big spoilers, all maybe have their place on the track for a one trick pony but not really much use for our cars used as daily drivers that we tune up for a bit of extra fun.

 

[gotmud]

I also get like a rolling idle when i first start it up when its stone cold , what would that be?
As soon as it runs for 30seconds it goes away.

The "shuddering" you refer to is probably the dreaded <2k rpm stuttering most of us seem to get with tunes and not your clutch. There are a few recent threads about it. Unplugging the speed sensor on your transmission seems to be a quick way to determine if the tune is the source of the shuddering.

 

[Seatman]

Why do you guys get that anyway? Has nobody figured that one out yet?

 

[Caddy 16v]

That's the first time I heard of the stutter with a tune, other than on the AHU with Rocketchip!

 

[A5INKY]

Mine is not a stutter and definitely not at 2000 RPM. It is a rhythmic idle speed change that only happens about 3-5% of the time. It began with the lightweight flywheel and has persisted through now three different tuners and dozens of tune files over the years.

I would try unplugging the transmission speed sensor, except my car doesn't have one...

I'm pretty confident I know what is happening with the "loping" idle. Not every TDI with a LW FW has the issue, but mine has. That coupled with no good performance benefit to LW and I don't think they are a good idea at all for a TDI.

 

[asap03]

So in case of LW FW, where do the un-dampened torque pulses end up? Can they actually destroy something in the transmission (shafts, gears, synchroes)?

 

[vwdiesel101]

in gas cars a lighter fly wheel can be advantageous as they rev more and dont have the torque out put, a well tuned tdi will spin tires in 3rd on dry pavement. that alone makes the fly wheel almost pointless even if it did make a difference.

So I just got my ECU back this afternoon from Malone with a stage 3 and the dynamics as well . . . Let me tell you, WOW! On the lower end it didn't feel like it changed much but put it down and it goes. Unfortunately (and I knew this would happen) my clutch is also slipping, not bad (I can drive normal without it slipping), but if I continue to hot rod it it's gonna go out in a hurry. If I am on the freeway in 4th or 5th at about 2200-2500 RPM's and put it down the RPM's just about 2-300 without changing speed at which point I let off the throttle because I don't want to fry my clutch just yet lol.

 

[gotmud]

Anyone else had a loopy idle for the first 30sec of a cold start up?

 

[gotmud]

Congrats on your stage3 97STROKER
Its really tough to not have fun when the car has some git up and go LOL

 

[97stroker]

I will let you know tomorrow morning when I start my car. Granted it will be only be about 50 degrees though. We will see what happens.

 

[gotmud]

Ok cool.
Thanks buddy

 

[97stroker]

No problem, what are the temp's right now up there for you?

 

[gotmud]

32 deg, way too dang cold.
I want a frostheater , my oil heater is not working.

 

[97stroker]

Dang, thats a far cry from 50 lol and then in the afternoons when I come home from work I have to turn the AC on! I have the frost heater in mine but haven't tested it. Maybe I will plug it in tonight just cause?!

 

[gotmud]

Ya got a frost heater. How was the install?(difficult)

 

[amstel78]

That shudder is the DMF dampers reaching their limit on low RPM, peak torque moments past 350 ft. lbs. Let me guess, it feels like a chattering that occurs at the torque apex, lasts about a second, then goes away as the torque curve flattens out and drops?

Yup, same thing happens to me with my Malone Stage II. It's not the clutch. You'll get used to it after awhile.

 

[gotmud]

Thats what it feels like. The tdi only make like 240 torque with the stage3…kinda wierd it make that shudder.

What year or engine TDI do you have? Different DMFs are used through out VWs product line; some just handle torque a bit better than others.

In my case, I'm a little north of 355 lbs feet of torque so when I accelerate and peak torque is reached, the DMF starts to complain. Probably won't last much longer if heavily abused...

 

[97stroker]

I didn't even see this! (someone else said earlier I should probably get glasses lol) Thanks! How long have you had your stage 3 gotmud?

Im not certain about what you are talking about with this shutter amstel? If I floor it the RPM's go up about 200 or so without a speed increase to indicate that. Is this what you are referring to as a shutter or is that my clutch slipping like I fear it is? Got mud does yours do something similar to what I am describing or am I way off base of what you are talking about?

 

[97stroker]

Wouldn't know that PO had it installed, he lived up in Illinois where it got fairly cold.

Ya got a frost heater. How was the install?(difficult)

 

[gotmud]

My car is a 2001.
I have had the tune for 3 months and i put the pp520's in anout 1.5month ago.
Mine does not jump 200rpm up like yours, it just seems to pull. But i am sure that eventually i will have to do a clutch.
