Hello all. I've had to back off of the web for a bit due to personal issues.

However, I would like to showcase quite possibly the first 15 DD R/T achieving "safe" & "first" 550 RWP. We'll have to see those "firsts" for the 15's but I've found nothing.

I'll have video's and updates later. But wanted to share this with the DD crew.

Had quite a slew of issues with the installer, not sure how to reflect on them, yet. I managed worked things out with the tuner and he has done great. I won't be doing a reflection of them until some time has passed to see how the vehicle handles.

Preliminary mod(s): Whipple Supercharger, ARH Headers (1 & 7/8) & full straight exhaust (ceramic coated), and Alky Methanol Kit.

Impressive! Congratulations!

 

[Chase300]

I assume the Methanol kit gave a nice boost.
She must fly now...is it RWD or AWD?

 

[DrDurangoTx]

Rear wheel drive.

 

[Citadel Brian]

Congrats you lucky SOB

 

[caskey_b]

rear wheel drive.

=more fun!!

 

[Thunderhorse]

Can't wait to see the times!

Congratulations Patience paid off

Amazing numbers, congrats! What a BEAST

Video, and engine bay to come later.

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?

 

[DrDurangoTx]

Thank you sir!

Yes, 93 w/ meth injection that activates on boost.

Torque curve is interesting, takes a lot of revs to get over 200 lb.-ft., but then it takes off at 4,100 rpm and your up over 500 lb.-ft. 600 rpm later. I thought the Whipple would be adding torque right from 2,000 or so.

 

[DrDurangoTx]

I'm going to guess and venture to say that was done by my tuner.

Congrats! Nice job! Have you done the MDS delete, is there a cam, or anything the Rams/Challengers/Chargers are doing? P.S.wheel and suspension info????????

Thats more cam related typically, but it also common on variable geometry turbos and such. The Hemi has VVT doesn't it? could that be turned? Reason I ask is the cam and VVT Dodge uses in the Pentastar gives it higher torque than the 5.7 Durango in lower RPM bands as its full torque from just above idle. Thats why they are almost the same 0-60 and close in tow capacity.

That's awesome man! I'm glad you got it worked out. This reminds me, I need to finish messing around with my meth and get it retuned.

I think that's more due to the fact it's an automatic on a chassis dyno... the engine dyno graphs I've seen show a broad torque band and making about 300 torque starting at 1,200 RPM and peaking at 4,000rpm.

Side note, assuming ripp superchargers before dyno pull of 280 all wheel horsepower, and accounting for the 23% drivetrain loss, you're pushing at least 677 horsepower at the crank.

MDS has been removed. Not sure on the cam department.

This is the place where I had my kit made from: Alkycontrol Methanol Injection Systems

There were a few others out there, but after speaking to the owners and no one having really done a Durango... Alky, IMO, seemed to have their stuff together.

I know other people that have used them as well and I've heard good stuff.

I'm very curious about where everything was mounted and all that. Where'd they put your pump? What are you using for a reservoir and where'd you put it? Are you spraying into a nozzle or are you using some sort of plate system?
