I placed my order for a Shaftmaster 3.5" aluminum driveshaft today. There will be a "TacoBill" approved write-up for the install since we'll be installing it at his place. There will also be some vids from inside the car to try and show the lack of NVH and or vibrations. In addition to that I'll be doing some before and after track runs in hopes of showing the the difference in et's. I'd like to get some dyno runs but being that I'm not taking it to a shop to install it would be a good bit of $$$ and time to take the car to the local performance shop twice. If I could find a local shop willing to do the pulls at a discounted price I'd be more than happy to.

Little background on my car...
06 GT/ Automatic Tranny
Lowered with Steeda Ultralites
BMR LCA's and Relo Brackets
4.10 gears
Rest of the mods in sig but they don't have any effect on the driveshaft.

I will provide a fulll and honest review once the install is complete.

Thanks to Robert & David at Shaftmasters for the opportunity to test their new product.

thanks in adavance for your contribution....lookin foward to the results

 

Why don't I ever get to be a test mule? Maybe one of the supercharger companies would like for me to test something for them?

 

I would go for that too.

 

+3 Ditto for me on the SC!

Congrats Leo! I'm excited to here about the performance difference.

 

Leo,
Looking forward to the challenge. I feel like I am back in high school preparing for a big exam. I think that we are up to the task and look forward to what I think will be positive reviews.
Robert

 

Which one did you get, the one with the adapter or are you replacing the pinion flange? Also, while you're under there, maybe you could measure your pinion angle (from the face of the rear flange) just to see where it's at during your test. You didn't mention if your LCAs are adjustable, so guessing they are not. The pinion angle should be at -0.55 degrees which is the stock angle.

 

I'm sure you have a great product. I can't wait to get it on my car.

I got the one with the adapter. I think it's easier than having to hassle with the pinion flange. I'll make note of that and try to remember to measure the angle. Regardless of the angle I don't forsee an issuse as Bill has already installed a once piece on his car with the same drop kit and didn't have any issues. (Crossing fingers)

BTW- I have the non adj. LCA's.

 

Good, I hope it all works well.

 

Yes!! Keep us informed!

 

Leo,
Just finished your shaft. It ran "DEAD NUTS" in the balancer. I enjoy balancing these aluminum shafts because they run so much smoother at high rpm's than a steel shaft could ever hope to. I am confident that you will be pleased. It is going out UPS today.
Robert

 

Robert, are the shafts balanced with the adapter? I bought one of your 4" aluminum shafts with the adapter and I was wondering about that.

 

Ned,
I am glad that you asked that question, it gives me the chance to address this issue. All of these Mustang replacement shafts are balanced from flange to flange whether it is for a V-6,V-8 with or without adapter plate. So, to be perfectly honest with you, no it is not balanced with the adapter plate. We could invest in the tooling to do this, but quite frankly don't feel there is a need to. We haven't had any issues with our adapters, which are made at a local tool and die shop. They are a machined part. Since they are a machined part they are totally concentric and balanced. Once bolted-up in essence it becomes your pinion flange. An ideal situation would be to balance the shaft on the car. This is not practical. Next would be to have the customer un-bolt his pinion and transmission flanges and send them to us so we could balance them as one unit. Also not practical. There are vendors on this forum that ask whether the competition is balancing these shafts with the adapter. I would like to know on V-8 models if the shafts they are selling are balanced with the replacement pinion flange they include with their driveshaft? If they answer yes, then anyone who has bought their product I have a question for you. Were there instructions to line-up the reference mark on the rear flange yoke to the reference mark on the pinion flange? Being that it can be bolted up more than one way there would have to be reference marks to maintain the balance. If we ever feel that there is a need to change our thinking, we will invest in the tooling. In the mean time anyone who is not completely satisfied with any of our shafts we will make you happy or we will refund your money. Just send us the shaft back within 10 days of receiving it. To date we have not had anyone request this from us.

 

Thanks!!

 

Dang, I want one of these.... big time.

 

I'll be going to the track next Friday. As of now my track times are between 8.6-8.8 depending on the run. I'm hoping that with my 4.10 gears I'll be down in the 8.4-8.6 range. I'll get a baseline of my time with the gears this coming Friday. That way I'll know exactly how much the ds nets me.

Install for the DS is set for the weekend of 21st.

I won't have any official track time difference untill first week or two of January. Because of the holidays the last track day of the year is next Friday.

I'd love to do it all sooner but because of the holidays I have no choice.

 

I have heard before and again in this thread to check the pinion angle after installing the driveshaft. This may be a really dumb question but how does changing the driveshaft effect the pinion angle? With all other things remaining constant how does the angle change? The angle of the propeller shaft on the transmission doesn't change and the angle of the axle pinion shaft doesn't change. So unless Ford no longer determines pinion angle as that angle between a line through the center of the pinion shaft and a line through the center of the propeller shaft I can't see how the pinion angle would change. Even if the procedure now measures the angle of the front flange to the rear flange it's all the same as the flanges are perpendicular to the propeller and pinion shafts, a little geometry can go a long ways.

Looking forward to this, an alum DS is on my short list of mods!

 

 

Leo you lucky dog... You'll have to share your d/s install... I may yet follow in your footsteps once more!
