Supercharger vs. Twin Turbos

So... I’m sure SOMEONE out there has a Supercharger OR Turbo(s) installed on their 370Z? What are your thoughts on the “upgrade”? What extra would you do OR not do?

Default Supercharger vs. Twin Turbos

So... I’m sure SOMEONE out there has a Supercharger OR Turbo(s) installed on their 370Z? What are your thoughts on the “upgrade”? What extra would you do OR not do? The company I’m looking at for my installation, charges 20K for the Stillen supercharger and transmission rebuild AND 30K for the FI Twin Turbo & transmission rebuild. 550 RWHP for the supercharger & 700 RWHP for the Turbos. Should I spend the money or just buy something else? If I buy something else, I’ll lose money on the car (of course)

Thanks for the input!

I think superchargers are more fun. Linear power. You get what you put into it. The more supportive mods to support other mods to support the desired power, the more you get out of it. Twin turbo is like free power to me where it doesnt take power from the engine and also the boost usually wont kick in until later RPMs.
I like low to midrange boost rather than mid to upper range boost. It supports my daily driving this way as well xD

At the same time, I think it is fun to upgrade superchargers haha.

Im also bias

Power can be addictive. With a Stillen supercharger sooner or later you are gonna hit a brick wall in trying to squeeze more power instead of a twin turbo system and believe me you're gonna want more power after a while. F.I. twin turbo hit hard at low rpms almost all the way to redline. At least that has been my experience with it. Go overboard with the fuel part. Don't skip on that area like some do

I'm at full boost at 3200 rpm. Superchargers are the ones that don't make full boost until you wind the tach out. Plus, torque is awesome, and SCs don't add a huge amount of it.

Find a new shop. Those prices are hilarious, and their quoted power numbers have no basis in reality.

Also, are you ok with throwing 20k in parts at a car, keeping another 5-10k in reserve at all times in case something happens, and then getting pennies on the dollar when you try to sell your Z?

I would go with the twin tubos.I do not notice lag.If you are looking at 700hp at wheels you will have to build a motor.If transmission is automatic it will cost 6k to build to handle hp.Then you have all the suporting mods to go with.If you realy want to make that much hp get your check book out.I do not see the Supercharger making 550hp at wheels.I would go with Turbos and tune to between 500 and 550hp at the wheels.Reliability with ample Horespower.Also the Z can be a handfull to drive at big horespower numbers.

You can allways turn up the boost for special occasions.

The FI TT kit with supporting mods and tranny upgrade, the price is about right.

Not if they're claiming 700whp with that. It's either the correct price for ~550whp, or way light for 700whp.

Sounds like you’d really like a roots or twin screw blower the best.

If you go supercharged to the Topgunz. RJM is making a roots blower I think. If you go TT do fast intentions or have the external wastegate done on the AAM

I currently have both ..2015 supercharged and and 2017 turbo ...and it is really hard to say which I like best ....both cars are completely different animals ..boost rolls in fast and hard with the turbo and there is much more torque but it feels like a stock car with power explosion when it does ...the supercharger feels more direct and connected and responds like a stock car with a lot more power ....both are great ...but I would say the supercharger would be better for daily driving and the turbo would be better for racing ...even though I daily drive both mine. In the end I am pleased with both ...the real trick is keeping traction with either car lol
