The pump system was inserted near the breaking fluid area if I remember right. We ended up using the windshield washer fluid reservoir for the methanol storage (Less intrusion inside the vehicle - low washer fluid light = add meth). We added, as you can see, a separate reservoir for the windshield washer fluid. However, I'm going to have to find a new home for that when I do a strut bar (https://www.blackopsautoworks.com/products/billet-strut-brace-wk2-durango?variant=28317951241). The methanol activates upon activation of boost. Which will drop the temperatures.

The vehicle is tuned with the capability to run without the meth, however, that means compromising motor temps. There's been some extensive tuning issues with my vehicle. It's not even a 100% right now I believe, the biggest problem was a blip issue (it's nearly non existent now). The shifting in automatic is balls, but that's due to the locked trans computer.

Congrats, that's quite a unique ride now! Looks amazing as well.

So 550 HP at 6,000 rpm, 519 lb.-ft. at 4,778 rpm. That's 190 HP and 129 lb.-ft. more than stock, really impressive gains. Can't wait for the video! Are you running on 93 octane?

He is saying 550HP at the wheels which means he is making more like 250 HP over stock once you account for drivetrain loss and the fact that the stock 360hp rating is at the crank.

Impressive indeed.

What type of blower is the whipple? It looks like a PD, but GreenD's breakdown of the dyno chart sounds more like a centrifugal

Using the washer fluid reservoir is an ingenious idea

Right, I missed the rear wheel/crank difference until Skippy pointed it out. I was assuming a Whipple PD, if it's centrifugal the curve makes more sense.

You're both right.

The Whipple is a twin screw and the old-school 8-71 air pump is the roots style--but both are examples of positive displacement (PD) blowers.

The dyno chart shows an almost instantaneous rise in power where the centrifugal power curve would be more gradual. It does seem a bit higher in the powerband than I would expect but it's still an on/off power curve that peaks relatively early and stays consistent throughout the RPM range.

Using the washer fluid reservoir gives you a built-in low fluid light in the dash. Plus, you can use the water/meth mix as washer fluid to clean your windshield.

I can't use it for that purpose because I do hundred percent methanol. Have thought about it. I really just don't like the thought of running water through my motor.

Ahh, I see.

The methanol is simply giving you more fuel that (1) is far more resistant to detonation than gasoline and (2) burns cooler. However, a significant majority of the cooling in water/meth systems comes from the water's ability to pull heat unlike other liquids.

The mixture is misted so fine that any water won't be locking up your engine or anything like that. It simply turns to steam when it hits the combustion chamber and exits with the rest of your exhaust. Plus, the steam has been said to (literally) steam clean the pistons, valves, etc.

When I get around to addressing mine again I'll be running a 50/50 mix because I want the cooling as much as I want the resistance to detonation.

100% meth is very flammable and the flame is completely invisible in daylight. Use caution. Definitely on the top of my list of worse ways to die - burning to death by invisible flame!

The pure meth will usually eat up a pump pretty quickly too.

Stay safe!

Video, and engine bay to come later.

What size tires did you go with? You rubbing at all? and last question you are still on Load leveling rear shocks right? Reason I am asking as I am getting Velgen VMB5 22" soon and trying figure out good tire size.

Only rubbing I deal with is when I hit a dip or a bump on the road too fast. It's making me consider getting a thinner tire possibility. I'm using my LL shocks. I also did rear control arms. I'll be doing fronts soon or your bearing deal.

 

[15RTrooper]

Yeah I thought that would be with the 40 seriers tires. I am thinking 295/35 or 285/35 tires. I will prob do rear controls sometime soon. But I waiting on my Bwoody adjustable ball joints to come in first as I really need to get the fronts back to specs.

 

[DrDurangoTx]

I'd like to know how that goes, please let me know on both the tires and bearings.

Did I see you say -2* on the fronts somewhere? I thought I read that. I used to run -1.8 on my lowered BMW but I know the D is a lot heavier.
Are the rears out of alignment too, or they align ok and you just need the adjustable ball joints?

 

[DrDurangoTx]

My rears with installed rear control arms are almost perfect. My fronts are a bit off, but my alignment guy said that it should have minor impact on my tires. Ill eventually fix my fronts.

 

[15RTrooper]

Yeah my fronts are 2.5 and 2.7 after alignment and rears are 2.3 both. But the rears measure that way I think that was done after the settled a little from LL and when it rises its is not that bad.

 

[12bschwartz]

Most impressive...still sitting on mine for dyno purposes because of the winter fuels here in Chicago...

 

[Bossman12r]

What part of Tx did you get the work done?

 

[DrDurangoTx]

Not even going to recommend the shop. It was a bad experience. Waiting for another mechanic/tuner to check and review all the work done. I'll be updating once I've had the work checked out.

Would ethanol have the same effect, like maybe running 50/50 E85 and E10? I'm sure your ignition could be tuned for this or even E85. I know some of the import crowd tunes their Evo's and STI's to run E85 and gain more power than E0/E10.
