Funny you should ask.... that was the next thing I was going to mention :lol:Hey Burkey
Are you also going to upgrade the drive shafts? I understand for the Roush and Harrop stage 1 SC's its not required, but I assume your going well past that in HP gains.
I installed “The Driveshaft Shop” (DSS) 800hp shafts a few months back.
Cost me $1500-$1600 landed, via eBay. (Ebay shipping kicks arse)
I actually had a fault with one of the nuts which trashed the thread at the hub end. Contacted DSS, parts were sent IMMEDIATELY, arriving at my door in less than a week from first contact. EXCELLENT customer service, highly recommended.
I chose 800hp axles because they get heavier and heavier as you step up in hp.
If reciprocating mass is the enemy of speed, big axles are my enemy. The increase in unsprung mass is also something to consider.
The DSS axles use Porsche 930 CV joints right up until a certain hp, at which point they change the CV. My theory is that if I break them, I’ll upgrade them again, retaining my old CV joints. DSS say that the ratings are quite conservative. We shall see.
For those playing at home, do you need heavy duty axles?
Does your car wheelhop? If yes, then possibly.
Are you launching hard on the strip with ultra-sticky drag tyres, then yes, it’s highly likely.
If you’re just having a play on the roads, using steel belted radials, probably not but the “shit happens” rule can change all of that in an instant I suppose :shrug:
