Manual turbo car steel/aluminum driveshaft?
Been working on my 1st gen camaro and just installed my t56. Now it's time to order a drive shaft. I was gonna order a pst aluminum one but since turbos like "load" on the engine maybe I should go steel. What do u guys think?
Set up is 5.3 with twin s360's
T56 magnum ford 9" 3.70 gear 28" tire
Ram twin disc
95% street car.

what you are all referencing is the rate of change of engine RPM with respect to boost vs gearing. Using a numerically higher gear ratio allows the engine rpm to increase faster. Think of spooling a turbo in 1st vs 5th. There just isn't enough time in first gear to see the "spool character" on a dyno sheet, it would look pitiful and short through 1st, some wont even reach max boost. That is one reason we like to use 4th, gives the engine plenty of time to sit and load up. So on the dyno graph it looks like the turbo spools faster, since the torque (boost) appears earlier in the RPM. If you could open the throttle all the way and hold the engine RPM still until the boost was there, then let it go (some engine dyno can do this) then you can see the output where the engine normally wouldn't be able to achieve boost on the street, except perhaps in its final gear at the lowest rpm possible, something you won't probably do on purpose.
As to the DS I naturally feel inclined to err towards the steel style. Aluminum does offer some rotating mass advantage, and if the manufacturer insists that it will survive it might be worth the go in an automatic vehicle. But you will probably not need or notice the difference, and the aluminum maybe physically larger and more cumbersome as well.
I would however, use the lightest wheels possible, and an adequate flywheel mass if manual. In fact if it was a manual trans, use the steel shaft for sure, it might help the drivetrain feel more solid or predictable. Maybe.

Thanks, I appreciate it. I've had very few people break the standard u joint girdle but the Moroso's are beefy. It seems to me the u joint yoke takes all the abuse, the u joint normally brakes before the u bolts do. Bob

I recently purchased the PST 3.00" 1350 series chromoly driveshaft from Bob@BruteSpeed for my 4th gen LS1 Camaro and it was spot on and works excellent.
The 3" diameter just gives me more clearance around everything especially with the fbody torque arm and driveshaft loops needed.
In my previous car I also had a PST 3" mild steel but with only 1310 u-joints also. That too was perfect.
You won't go wrong with a PST driveshaft and Bob is great to deal with.
