GT350 Shipping weight

Yet they are still using the heavy arse two piece steel DS. SMH... When I upgraded my GT500 to a CF one piece DS I dropped 38lbs rotational mass which helped engine acceleration and actually increased rwhp slightly. It was definitely noticeable while driving. I think I found another needed upgrade.

People who've upgraded the stock S550 drive shaft have found it isn't as heavy as they thought. One-piece aluminum shafts are only dropping 10-15lbs compared to the 30+lbs from the '11-14 models(not sure about 05-10).

An interview with Jamal said they couldn't get a carbon fiber drive shaft from their manf'ing processes stiff enough to handle the demands. That is from Ford though. I'm sure the aftermarket will fill in that gap.

The standard GT350 does have some weight reduction but also adds some weight back with it's huge brakes, perhaps the MRC is heavier(not sure), Tremec 3160 might be heavier than the MT-82, heavier axle shafts, maybe a few more things.

Home dawg, from my understanding they took into account the heavier brakes, magnetic ride, and other hardware when doing weight reduction. The aluminum hats on the big azz brakes I'm sure help but then fixed 6 and 4 piston calipers probably take another step back. Probably all equals out. I think a lot of aluminum was used on control arms, rods, and other such pieces.

That's good. I misstated the rotational weight drop was 28 lbs. The stock two piece is 43lbs on the '07-12 GT500. The DSS CF one piece DS is 15.5lbs.

That is interesting considering torque is the killer of driveline components and the stock CF driveshaft on the '13-'14 GT500 is handling twice the torque of the 5.2L FPC.

The other killer of driveshafts is resonance frequency. Shafts are rated to a maximum RPM and a one-piece shaft has limitations in this area. I'm not an expert in this area so I'll have to do some extra research but IIRC the center support bearing increases the maximum specific RPM of the driveshaft as the resonance frequencies are cut effectively in half.

The '13-14 GT500 had 3.31 gears which reduces the driveshaft RPM's at any given speed. The GT350 has 3.73 gears so I'm betting Ford was being cautions in this area.

I don't think strength was the issue, its was also said the cf shaft was the wrong frequency. Wrong frequency may leed to unwanted vibration.

Very true. DSS has tested their CF DS to 170Hz or 10,200rpm before failure thus I have no doubt the aftermarket will have a solution.

Shows an aluminum front bumper beam, perhaps some savings there over the standard GT PP

Why would the manufacturer care what fuel a dealer added? The computer detunes the engine as necessary for the fuel. Any enthusiast who cares about the weight of a car or modding a car is going to put the right fuel it in once they get it.

87 Octane could damage the Voodoo. It's very high compression and anything under 93 will cause issues.

Many states no longer have 93 where premium is only 91. I would think it is tuned for 91, no?

Dang, what I am going to do with my 91 here in CA (and many other states). Are you saying I will have issues?

Ford had a specific MSRP target on each level. I went over these targets months before the official release.

Since they did hit the target, the 2-piece shaft may have only been a budget issue. I'm sure it was explored and could have been responsible for the "more than 130lbs" statement.

However, I believe Ford will use the GT350 in direct competition with the Performance Pack SS, when one is offered.

This puts a brand new GT350 slightly over a brand new SS once optioned to compete.


This is still a profit vehicle, need to keep it that way so we can start on the GT and 350 improvements and the GT500.

Peak power numbers are with 93, but the car will just adjust for 91. Same way the coyote can work with 87.

It will be interesting to find out what minimum octane Ford recommends. I'm sure it will run fine on 91 at a minimum.

I bet this beast will really make power when it's below zero!!

I suspect that was the case as well.

Does the GT350 have similar adaptive tuning logic that the 2011+ GT500's have? I haven't seen any insight on this but with this high of compression the ECU has to pull some timing with any indication of detonation. Vastly different then a forced induction platform but similar strategy I would think.
