PSA: reassembly goes significantly faster when you have parts vs not having parts...

 

Really nice job, Darth!!! Especially the ET. Quite a few cars out there that can run 130-134mph trap speeds, but damn few running 134mph in just over 10 seconds!!! You are SO close to the 9s......Great job!!!

 

He's got the power, its the weight and being a DD is the best part.
true 9 sec n/a DD.

 

Thanks guys! That's the goal of this thing. DD 9 sec NA car. Even if it's 9.99x lol. I think If i can manage the launch better I should be good.

I'm actually home this week, so I'm hoping to get it driving before my next trip.

 

You got more in the 60. Just takes track time to find it.

 

Waiting for results, how the magnum shifts vs normal t56

 

Hoping to let everyone know soon. Exhaust is on, and all the crossmembers are in place. Driveline angles are all set . I need to address some exhaust leaks so I don't get stupid rich on fuel trims. I'm just not making any promises on timing, just because I cannot express how much I REALLY do not want to take this thing back out of service.

 

Take your time and do it right so you can enjoy the Hp and not have 2 .....

 

What output shaft comes with Magnum F?

Asking to figure if it requires different driveshaft yoke.

 

31 spline vs 28. I grabbed the sonnax yoke. It is 3/8 shorter vs the strange. Also, if your current yoke is a 1310, the new one will be a 1350. You need to figure that in as well.

If your rear LCA are adjustable you can sometimes adjust around the added length.

 

Noted.
Thank you Darth.

 

This happened!

I wasn't able to get a good rev clip, but I can sit in the cabin and it finally revs out like a banshee.

 

More progress. I was able to get the OE dash working effective today. The vids are over here....

Drove her around the block!! Some bugs to work out but she lives!!

 

Hell yeah... Like that throttle response.

 

Took her out for some exercise. My God, she's powerful. it may be that i's been a while since i have felt that kind of acceleration, but this is another level for me.

Tuning on the Holley is very different. You control the same stuff, but you do it differently. You have to train your brain to understand what is what. Fueling in my opinion is easier. You tell it what AFR you want in various places on the VE map, and it will trim to that AFR. Vs the stock computer that trims to stoich with the narrow bands and then uses multipliers. So, I idle at 16:1, go into deep deceleration at 17:1, cruise at 14.7, and full power gives 12.7. It's quite nice. Plus the factory computer, you cannot really see your fuel trims outside the log. in the holley, you can watch the log and tune at the same time. So you can see the learn values, and they're very straightforward. I did learn that i can command 18:1 idle, and the car will still run. But hwat happens is, the idle becomes very sensitive to learning. at 16:1, it is very stable. You can see it in the learn values. The trending side of the holley system is really much better than HPtuners. All the PIDs are always available and trended. you just activate and deactivate the ones you want to see. It's more like the IBA fast data acquisition software we use at work.

Timing is harder. I think I prefer the OE g/cyl load table vs the map sensor table. Especially since on the bigger cam, the entire bottom half of the VE table is irrelevant. My wife's tablet badly overheated while I was tuning, so I had to stop. But to say this, I was able to take a six mile drive, including some main road time, accelerate very hard, and not stall. Cruising was probably the worst. Just need to figure out what the cruising cells are in the timing table and push them to 33-36.

In other news, got the clutch bled down, and the transmission shifts so much better now. No issues with braking, lights, etc. Gauges are all in working order.

She's not track-ready yet, but I'm past the bullshit at least.

 

Gotta feel great to finally have it all (or mostly.... lol) sorted out!

 

Holley ftw

 

Big cam big throttle body is funny with the Holley. Like I paid for the whole table, I want to use it lol. Wish it were possible to increase the resolution of the table in the useable areas instead

 

Having two timing tables similar to GM has helped my low speed drivability a ton. I treat the base timing table like the GM high octane table. And then added a custom 2D table to modify spark timing at very low throttle conditions (pull timing at 0% TPS in my case, which also helps engine coast down to idle).

My low & no throttle conditions were basically overlapping below 2000 rpm so it was impossible to make both happy and my engine was bucking. Being able to command different timing based on TPS has helped a lot.

Got the idea from a guy on the Holley forums by the name of quarterbooty
