Have you asked Stuart if he has a tune available for the John Deere? Could have been done in half the time...

 

DJS has a valid point. And I think I speak for all of us when I say we'd like to see the Deere running on a tune.

 

No supercharger or tune (yet), but I have added a front bucket, a rear PTO, a 3 point hitch, a ground ripper and 240 lbs of suitcase weights to my 1991 JD 420. I have a couple of OEM spot lights in a box that I'll install for snow plowing (one forward facing and on rearward.) That's in addition to the standard headlights.

 

Yes...More Cowbell!

I'll record the sound from inside the car when I get it out of the garage and onto the road.

 

Definitely more cowbells, definitely.

 

Waaay more cowbell, sounds like a whole herd!

 

this is the sound I can hear when I install lower mina tubes?

 

Yes.. .with their 6 ply filter cones.

 

what do you mean by 6 ply filter cones?

the one supplied when purchasing lower part of mina?

 

you already install upper or lower pulleys?

If it is, s/c whine might not come even I install the lower part of mina as I don't install pulleys.
What do you think?

 

Aaaaaaaand add to cart... That sounds delightful

 

Lance (Unhingd) has both lower and upper pulleys and has commented many times that the upper pulley on the V6 is a waste of time and money.
And it's not the pulley(s) that increase the SC whine, it's the VAP lower pulley tune that does so, by keeping the SC bypass valve open sooner and longer.
But it seems that the Mina lower intake tract with those cone filters takes it to a whole 'nother level, mainly by getting rid of the central baffles/resonators.
So in your case just going with the Mina lower intake tract will probably give you the SC whine you desire.

 

Yes.

Installing the two pulleys did virtually nothing in my case to increase SC whine. Adding the upper Mina intake added just a little whine. As Oz says, the lower intake takes the whine to a whole new level.

 

That settles that. Placing my order.

Also, the JD 420 is a wonderful machine. The Army sent me to JD HQ for 2 weeks in the Quad Cities in 2001 when we were acquiring their 230LCR excavator. Great company, great machines. They put on a hell of a show for us.

 

I'm not debating for aestethic purposes to replace the upper portion. I truly beleive that the OEM air boxes are excellent at funneling cold air into the intake and will not mess with the lower portion even though it muffles the supercharger whine.

 

you think that mina open filter isn't better in intaking airs ?

 

The Mina open filters system almost certainly does not flow any better than the stock system with paper filters, filter boxes and intake trumpets as the stock system is pretty damn good.
But chopping out the resonator/baffle pieces releases a heap of otherwise muffled SC whine.

 

that shutting down had a clunk to it, is your car ok???

 

I reckon the clunk at the end is Lance opening his driver's door!

 

If you are referring to the shutdown noise at 0:18, probably not, but it’s been like that for 35,000 miles. I suspect it has the old SC coupler design.
The clunk at 0:21 is indeed the door closing.
