I know a little but I not a lot so my question is this.

With a SS and adding a supercharger, what other components would need needed other than intake and exhaust? Obviously quality fuel and tuning but what about the internals? When do you start needing forged rods/pistons and everything else?

Talk to Dave at DDM. I had mine boosted this summer at his shop. I have put 2,500 miles on it since then with no problems on a stock engine. Best money spent to date on my Slingshot.

I am going ddmwork super on stock motor with exhaust and it will give 285hp

I am sooo embarrassed! I thought this thread was going to be about taller seats for really short drivers.

You simply buy the SC kit. It comes with everything you need, except for your exhaust setup. Most people seem to be using a 1320 header and a Welter setup.

A decent AFR/boost gauge would be nice to have to monitor everything.

You build a motor when it blows up. There are a ton of variables when this may happen. But the old rule of thumb of staying below 300hp probably still generically applies.

With our base supercharger kits you can run the complete stock exhaust and catalytic converter if you would like, however you will make less horsepower than with an aftermarket exhaust and no catalytic converter installed (stock hp is 145, supercharger,stock exhaust and catalytic converter 225hp, supercharger with catless exhaust 280hp). Typically most of our supercharger customers have at a minimum an aftermarket exhaust installed on their Slingshot though since it is a large difference in power. The tune and intake are included with our kit. So far, no one has blown an engine with our base supercharger kit that I know of, that is without ARP head studs or anything else installed in the engine. Typically we start recommending forged rods and pistons and engine builds when you start getting over 300hp to the wheels on the turbocharged engines, but the Slingshots with our supercharger are living a little higher horsepower than that right now.

Hope that helps,
Dave

Reviving this old thread because it's right in line with questions I have in another thread. Dave says all stock exhaust nets 225hp. What would header and catless exhaust with 2" out the rear get. I know 2.5" is the ticket but already have the 2". Is 250ish in the ballpark? Trying to justify pulling the trigger on the system.

I don’t know the answer to your question, but I’m running Dave’s kit with fully stock and catted exhaust (so hopefully 225HP +/-) and it’s a blast compared to stock... No comparison at all really. And no regrets! Yes, It’s a lot of money, but 225 vs 250HP probably shouldn’t be what justifies pulling the trigger.

Good luck with whatever decide!

Thanks Bugal, I'm sure I'll get it. Hearing you're happy with the sc power on an all stock sling I think just pushed me off the fence. What size pulley are you running with a stock setup?

Stock exhaust or 2" systems get the 110mm pulley on the supercharger.

Thanks Dave, in the post above you said the sc with stock exhaust is 225 hp at the wheel. I have the header with catless mufler & j pipe with 2" rear exit. What hp do you expect that will make?

I love my DDM Rotrex SC kit!!! Go with a 2.5 cat-less performance exhaust, metal overflow coolant tank, Coolant re-route and that kickass smaller pulley.
Also, dont forget...
2 rear wheels puts down twice as much power to the road!!!
Thanks Trackhmr!!!
LOL!!

Should still be right around that same power, since the exhaust is really the limiting factor.
