I tried search. but the search function won't allow "ss" because it isn't 3 characters BRIAN!

Anyway, what is the solution to dyno tunig the SS with AWD?

 

Todd,
We ordered a Mustang twin drum AWD dyno. Should be finished some time this month.

So is this the only option Kurt? Is there a way to drop the front driveshaft or something? Not familiar with the setup at all.

 

Todd,
The driveshaft must be in to dyno. I tried to dyno a H2 with the front shaft out and computer would not give full throttle because wheel speed difference. The new mustang dyno will make it easy.

Although no one has done it yet, Dynapak makes adjustable dynos that supposedly can support the weight of the SS. The wheels are removed and the dynapaks are bolted on. Like I said, nobody has done it yet.

I spoke with the owner of Knowledge Performance Inc. in Atlanta, GA on Wed. He says the system is capable. The only problem in this particular case is he's short one set of 6-lug adapters. The cost for them is minimal, and if we can get enough people to go, he says he will purchase them. There is at least a few of us that expressed interest, including myself. He only wants four people to committ.

We'll see how it transpires over the next couple of months. Hopefully a few of us will have been dyno'd there by then.

One member on the SS site posted some dyno numbers a while back for a SS that had the front driveshaft removed for a dyno run and didn't seem to have any issues with it. It was heavily modded with at least 150 shot. Believe the hp was over 600. I'd have to do a search to verify.

I also believe I saw a dyno shop in the OH area that also used the dyna pak dyno. You may want to look into it.

 

Yeah, I saw an SS dynoed first hand with the front shaft removed.

This is a SS with good heads, a big cam, tuning and a muffler. No other real mods (stock intake tube, air box, fans, cats, pulleys). The big number is a direct port 200 shot. You can tell that the intake and exhaust choked the nitrous run after 5500 and the fuel started leaning out.

 

What say to those posts Kurt?

Big Tex - was that run monitored with ATAP or similar for timing?

 

someone on sliveradoss.com said it wasn't a good idea to remove the front driveshaft. said it would destroy or seriously damage the transfer case.

 

Todd - The truck was dyno tuned with LS1 Edit. I'm pretty sure they used a Tech2 and a wideband to tune.

I posted that info on Silv SS saying GM says you shouldn't drive it with one driveshaft. The AWD transfer case has a viscous coupling that allow a little slip (so you won't have issues turning corners) but will engage under major slip. When a wheel slips, the fluid heats up, putting more pressure on the friction plates of the driveshaft with most traction. The fluids in the transfer case cannot be replaced, so if you burn them up, you have to replace the transfer case.

That being said, I will risk a couple of 10 second dyno pulls in my SS pretty soon.

 

Todd,
Depends how "Reckless" you really are. We have blown up a viscous coupling box with shaft out. GM owned the truck and they wanted to try it(with design guys yelling NOOOOOOOOOOO)
Torque management in computer will go crazy if front wheels don't spin.
Local guy here went over Niagra falls with no protection and lived.... but I would not try it. LOL
