Man Gdonavan, that car is beautiful! Total dream car for me, I really hope you enjoy it all over again! Best of luck and please keep posting on progress, thanks!

Thank you! She's far from perfect but the two of us have been knocking around since 1986.

Spare 52 and 59 jets on order

Use the jets you have..........I see some 47s there. So leave the 52s in the nitrous side, drop the fuel down to those 47s, flow it at 5 psi and let it eat

How hard were you launching it with the 8 3/4 and the 4 speed? What was the clutch out of curiosity?

Tough question-

When I was racing the car a lot I was running a Dana 60 with 4.56's, it didn't see a lot of action with the 8.75" till I installed the automatic.

I really wish I had a chance to run the car with 4.10's and a lighter flywheel, I figured out a few years later an excessively heavy SFI 11" flywheel was the cause of many launch issues. A touch too much gear and a flywheel too heavy.

Launch was pretty much by ear (still is) the lights come down and I let it fly...

Good luck Gdonovan with that nice Mopar. Ron

I'm going to play it safe and run the 52/52. If I get a second pass with the bottle I will up the ante to 59/59.

Thanks! I hope the Duster comes together soon too, I should have transmission parts on Monday.

I might lean out the jetting along the lines of what monte posted, but best of luck and post up the results!

I'm just being conservative- It is still leaner than what I ran "back in the day" using the advised NOS settings at the time.

If the car runs 12.80's off the bottle the 52/52 setting should give enough extra snot to put the car in the 10.90's.. which is all I'd like to see.

59/59 would put the car in the 10.50 range.. which might make the track officials a touch angry.

Don't know how many times I have to say this on a daily basis. Rich tunes are NOT SAFE. The only safe tune is a good tune and a dead rich one ain't it. TIMING is what tears up parts, NOT lean.

My kid has a junkyard motor that smokes.....runs a plate with 52n 47f 5.0 lbs flowing.....hundreds of passes on it... That's safe ! Lol

Running turbo's Monte I'd not agree with you 100%, seen lots of turbo engines burn being too lean. Better to be a little cautious in my book.

Too much timing is bad too, seen lots of people kill pistons that way as well.

I ran the same jetting on my smallblock, no issues ever.

When you say 5psi flowing. are you flowing through the target 47 jet, or a 73 jet? I always see advice saying to flow the fuel through a 73. Is there something to using the 73 jet more than it is just a good reference?

We are not talking about a turbo motor here. We are talking about a nitrous combo, which is STILL an N/A motor...........because to make power, it still relies 100% on the air it draws, NOT air that is forced through it.

Now while it won't likely make much difference at the low power level you intend to use.......a rich tune is about the WORST thing you can do to a nitrous motor. So NO, rich is NOT safe. Now obviously you are free to do as you wish, but why not do it right

Will be running twice as much, dual quad remember?

It's only "twice" as much if you have twice the solenoids, which to my understanding, you don't. It would appear you have one nitrous and one fuel solenoid, with T fittings, feeding a pair of plates.

So while the single 52 jet is roughly 100hp on a single bar plate, depending on solenoids used, when you double that jetting, while still flowing through only one solenoid, it only makes about 50 more hp.

These power outputs also change depending on the nitrous solenoid used. Given the same jet, power levels will be different with powershot, cheater and pro-shot solenoids. The number on the jet is just a number. What matters is what it flows and that depends on the components used

Cheater solenoids

A .073 jet in the flow tool is just an nos industry standard. I always leave it in there
