3) Peak hp & tq
4) List engine type and all mods
5) Post a picture or chart of your dyno report

[bad360rt]

This is a mix of dyno #'s and track times, but gives folks an idea :biggthumpup:


Paxton, 55mm F&B, 4bbl M1, 1.7 rockers, GS headers, 2.5" duals w/cats - 13.5@104 at 10psi, dyno'd 346rwhp/383rwtq at 8psi, on 93, pulling timing

Added M.Saine VB & 2800 stall, 13.1@107

Dyno'd 386rwhp/392rwtq after sorting out some fuel issues and gutting the cats

Added B&G blower flash 12.5@111

Great weather - 12.1@114 (37* and 57% humidity)

Added 2.02 heads & intercooler & crank pully, 11-12psi 12.0@116 dyno 452rwhp/449rwtq

Built PowerDemon tranny w/2800 stall goes in.

Better weather 11.87@116 (killed the stock bottom end on the next run, 11.9@115)

All of the above was on stock cam, stock bottom end, stock front wheels, 28x12.50 ET Streets on Real Pros, tonneau and tailgate on.

Dropped in a Mopar replacement shortblock, swapped the 55mm for a 58mm F&B and had a valve job done on the heads.

Ran 12.1@114 in the heat with DR's on stock wheels

Ran 11.9@116 with a full set of Bogarts, 28x13.50 QTP's on the rear, still hot out and still breakin in the QTP's (June)

Added shortbelt, 11.9@119

Lil bit cooler (67*) and more practice with the QTP's, 11.6@120

Dyno'd 493rwhp/473rwtq at All Trucks, in the heat.

Ditched the dinky lil stock Paxton air filter for a 9" S&B Big Mouth and 4" intake, hitting 15psi, ran 11.3@120, had to let off on the topend cause it was running lean. Dyno'd 592rwhp/547rwtq, but I think the dyno was a lil happy, calculators said I was around 560-570rwhp.

That is the truck as I received it. 210 cam, 1.92 r/t heads, m1, tom fox flash, pph headers, holley 52, 21lb/hr injectors

http://home.comcast.net/~seanmca79/af_diff.jpg

Switching to 19's actually made more power.

http://home.comcast.net/~seanmca79/360_100shot.jpg

Back to 21s on a tuned 100 shot.

http://home.comcast.net/~seanmca79/n2o_jets.jpg

Why you should tune your n2o shot. 40HP left on the table with the NX recommended jets. I wouldn't run on the blue curve there. That went too far.

http://home.comcast.net/~seanmca79/150dyno.jpg

Diesel torque, parts breaking 150 shot.

http://home.comcast.net/~seanmca79/gsm_dyno.jpg

Switching out to full GSM exhaust, Tom fox reflash, and a F&B 52x55. Result is a little more power above 4500, track times say nothing. Wallet says ouch.

http://home.comcast.net/~seanmca79/ms2dyno.jpg

Why you tune beyond a canned flash. That is the result of switching to 24lb/hr injectors and tuning with a Megasquirt 2 system set up for fuel only. The difference in torque down low is very noticeable. Part throttle driving that you can't see here is really felt in the seat of the pants. The missing torque at part throttle in the Tom Fox tune is obvious just driving around normally.

The truck now has a set of ported Eddies along with a ported M1. Dyno numbers at Spring Cecil. I doubt I'll race it again.

[DrewzR/T]

Just a baseline to see what it runs before I threw on the vortech and Meth. I was actually pretty please with the numbers it threw down with only these mods. Must have been built on a Wednesday! haha

The numbers actually back up the 8.93 1/8th mile I ran.

Mods
GSM R/T Big Tubes
2.5 inch true duals w/cats and Bullets
M1 2 barrel (unmolested)
Viper fan
FIPK

Dynojet
Max WHP - 245.58
Maw WTRQ- 300.50

My runs were a little on the rich side as you can see.

My boys 01 R/T with Eddie Heads, 210x, 1.72 scorpion rockers, M1, SCT, 53mm TB, Big tubes, true duals and bullets put down 293hp and 334ft lbs.

So yeah I'm pretty stoked.

heres a vid and graph

ok lol theres something ur not mentioning in ur post unless ur race weight is at 3300lbs or something and in a durango i dont see that happening.

[Durango Kid]

My race weight is 3575,weight distribution is as important as weight.I also have caltracs.but no nitrous or boost.I will take good pics and post them.I have many little tricks that add up to tenths and tenths add up too,but like i said,i race EVERY week for 6 years in this car (200 - 300 passes a year x 6 years,hows that for test and tune R&D) ,trust me,I got it dialed in! oh and the Vyper 3000 stall converter and a B&M shifter.
MSD HVC coil,moroso 40 wires and a mallory digital ignition throws a big spark to the NGK Race Plugs 5271 A8,4 quarts mobil1 0w20,K&N oil filter,type f tranny fluid,and the return fuel sytem keeps it from leaning out at 6100 RPM's,I'll send pics out tommorow

IT's true. I am the second set of hands when need be.I spent plenty of nights drinking and turning a wrench with the durango kid.In fact some of his hand me down parts make up my truck.:D

[Addicted2Blue00]

http://home.comcast.net/~seanmca79/af_diff.jpg

Switching to 19's actually made more power.



just what ive been wondering, still have my stocker 19s, shes running so rich w/o a tune ive been wantin to know if swappin to the stockers would hurt it.


is it better to run a single 3" or dual 2.5" w/ x pipe?, both with turndowns before the axle. ive been also debating on the exhaust, 2.5" downpipes but unsure on the rest and i rather have power over sound as it has PLENTY of sound now.
if anyone is wondering my setup fastman 52mm tb, 4bbl m1, 210x cam, 1.6 RRs, eq heads SS 2.02 intake 1.65 exhaust valves 5 angle valve job .600 springs, double roller timing chain, asp crank pulley, shorty headers no cat which i havent put on a dyno yet.

Thanks - Only ran once last year and had a few issues but it was on track for about a 11.1 pass. Used 28" X 10.5" X 15" MT Drag Slicks.

Anyways moot point now blower is sold and truck is going a Turbo set-up to debut this spring. Just hope the Magnum block holds together.

[Siciliano15]

sorry for taking so long to respond i couldnt find the post....... but yea now i see with the 3575 race weight that it can be believeable haha. Its still impressive however and wats even more impressive is how u got a durango to 3575lbs. thats about 70 pounds less than my r/t!

[ChrisR/T]

Your R/T only weights 3650?!?

Mine weighs like 4200lbs. :(

[2k1AmberR/T]

Your R/T only weights 3650?!?

Mine weighs like 4200lbs. :(

Ditto, how'd you get a R/T to 3650 pounds? That's some serious weight reduction. Aren't most RC's somewhere around 4000 or so at least? Like ChrisR/T said, 4200ish is probably realistic. That's for his RC, too...I haven't ever weighed mine but I'd imagine it's 4k+, I don't have any power windows or locks yet haven't done much in the way of dropping weight.

[Five9Dak]

I was at 3800 with 140lb driver before the blower. Now its back closer to 4k I'm sure.

Boyd front wheels(ligher than R/Ts), slicks on 15s, no spare, no gate, no jack, no heatshields, roll pan, custom aluminum driveshaft

I recalculated it it actually weighs 3680lbs without me in it. didnt really do any major weight reduction. only things i can think of are the rollpan, the edelbrock aluminum heads, i never drive around with a spare tire, and i took out the air conditoning system. besides that though i didnt gut anything out of the truck because i didnt want it to look like shit. if ur sitting in the drivers seat the truck looks 100% stock besides the headunit.

Yes. That would qualify. A 9.25 with a girdle doesn't count.

Haha, you guys have no confidence in that rear end. Sean, did you break something physically in the rear end? Or just U-joints and yokes?

Here is with the A/F part opened up. It was NOT happy.

The boost level was going into a sine wave - and the FMU was getting behind... and the HP went crazy. Inside the truck it felt like a bad set of plugs except for when the converter would take some time out. The rpm would increase but the mph stayed the same.

Got big dips in it??

Rollercoaster bucking bronco ride dips....

Hahahahaha.

The owner of the shop rolled out a big tub full of kitty litter and a shovel. He said if I kept making pulls I was going to need it. LOL

I think I see a Pterodactyl in there!

I really like the loop t loop. That's crazy

That is some shit.

I've had some pulls where my AFR went nuts, misfiring, carrying on and it still didn't look like that.

I'm gonna throw out a guess just for the hell of it.

My dads Chebbie bucked, popped, snorted, and farted like crazy when his CPS got grounded out.

Any chance you damaged the cps, wires, flexplate, or anything else when you swapped the converter?

EDIT: you pulled out a viper converter right? did you pull out the BH and flexplate spacers, too?

It only went this crazy with the boost controller on. Apparently it's cycling the solenoid open and closed to regulate the boost pressure that gets to the wastegate. Then the wastegate opens and closes to try and keep up. Then the FMU is seeing this boost pressure rise and fall - which makes it's diaphram do the same. The problem is that not all of these components can cycle at the same speeds. Once any one of them starts to fall behind it starts to go stupid. Turn the electronic boost controller off and it stays at a solid 12:1 A/F and 10 psi of boost.

My buddy tried an expensive electronic boost controller and it didnt like it at all, it would surge under boost terrible and nobody could figure out how to tune it so he sold it and went to a manual set up

Lol, guess I gotta go back to school and brush up on CBE troubleshooting :jester::hail:

I was talking to Gary about your truck last week, I would love to see that thing run in person :biggthumpup:

Here is a very much less dramatic snapshot of the power output. Relatively flat power output from 65 mph to 130. The single red line - Lean A/F line is when I turned the boost-a-pump off to make sure it wasn't a source of the phasing. Leaned it out by a full A/F point.

I'll ditch this and go back to just swapping springs in the wastegate.
