i'm interested in buying a g35 as a daily driver but i'd need more power (coming from a 450hp supra.)

the stillen stage 2 kit is the most appealing to me b/c 1) CARB legality and 2) warranty. i already have the supra - i don't need the highest performance; just acceptable performance.

has anyone dyno'd the various stillen stages? i'm interested to see the entire rpm curve.

if you have dynos, please post w/ all of your supporting mods.

thanks,
chuck

98 supra tt - 450hp @ 17psi - BPU++

 

Remember... peak horsepower doesn't say it all.

From two posts by Stillen on my350Z...

Stage 1 STILLEN Supercharger: 305hp
Stage 2 STILLEN Intercooled Supercharger: 316
Stage 3 STILLEN Intercooled Supercharger: 335

**These numbers are what customers are posting on the this and other boards. SKK100 is a great example and person to ask about the benefits of the Stage 3 kit if you want to talk to a customer about it - to get their impression.

The Stage 3 Setup is as simple as changing the pulley out for a 7-lb pulley. It's a very potent upgrade for under $100!


These are the numbers from the Dyno Shoot Out that we performed with Sport Z Magazine. Please note that these numbers are straight off of the dyno charts. The dyno charts get a bit messy to read when all of the lines cross each other. So, this should help. You can see from this that if you are looking for everyday driving performance in normal RPM ranges - which system provides the best performance. If you are drag racing with gears that allow you to operate at very high rpms, or like the peak gains, then the other units will be of interest to you. They each have their merits.

Reported peak horsepower and torque values:
Baseline:....242.5 hp @ 5800 rpm 239.4 ft/lbs @ 4600 rpm
Stillen:.......338.2 hp @ 6600 rpm 302.6 ft/lbs @ 4200 rpm
Prochgr:.....353.7 hp @ 6600 rpm 300.5 ft/lbs @ 4800 rpm
Vortec:.......344.8 hp @ 6300 rpm 298.7 ft/lbs @ 5900 rpm

Also, please remember that while these results are posted, each vehicle will vary to a certain extent due to OE manufacturer differences, dynos and production tolerances. These run with Carl Merrit of Sport Z Magazine driving each car on the dyno. Same day.

Hope this helps decipher the gains for these systems. The question is where do you want to experience the gains.

thanks DaveO, i couldn't find any dyno numbers for the stillen kits.

and yes, i wanted to see a dyno for the stillen stage 2 to get a sense for the powerband over the entire RPM range, not just peak as they advertise on their site. the other 2 kits don't interest me b/c they aren't CARB-approved and not warrantied.

these numbers look good - now i just need to find a ride in one to make sure.

 

DaveO, do you happen to know supporting mods for the dyno?

Did each car have intake? headers? exhaust? stock or upgraded clutch?


thanks,
chuck
