Superchargers for the 370Z?

Crash · 03-09-2009, 11:05 PM

Honestly, I'd like to see a twin super charger kit for the Z. It's got the perfect platform for in.

Just to clarify...It would actually be ALOT easier if we could use our standard, Eaton supercharger on the 3.7 dual throttle body engine's. We would basically just replace the manifold like we did on the 3.5 liter's and design a hammer head style intake tract coming off the throttle bodies. It would look awesome and work really well. However, the current supercharger that we use on the 350Z liter, 62 CFM displacement would be undersized for the 3.7 liter. We would really need to jump to the larger 90 CFM blower which unfortunately creates the need for a new hood.

Development on our forced induction kit is coming along nicely.

Do you think you can come out with an option of a bigger supercharger. The 350z supercharger kit was a big letdown. Maybe something rated for 500+ hp this time.

We don't drive a V8. A supercharger that nearly doubles the stock hp output will be overkill and won't be as reliable. I'd be very happy with a 400 whp supercharger kit.

For starters- I am at home right now and read this thread and can't remember what my password is so I had to create a new screen name hahaha...sorry...

Welderz-

The supercharger for the VQ35 liter engines that STILLEN developed achieved every one of our goals. It was not intended to be the highest horsepower producing forced induction kit because at the end of the day, that only matters at the drag strip or the dyno.

The greatest aspect of an Eaton, positive-displacement supercharger is its daily driver and race track prowess. Because the Eaton blower produces instant boost at low RPM levels there is no lag and therefore it offers amazing torque at low RPM's...Where you drive daily and where you want power when accelerating out of corners. Also, the linear powerband of an engine with an Eaton supercharger speaks volumes of its performance.

One thing to consider with the 3.5 liter is that the blower we selected was chosen for two reasons. 1) Its size. The smaller size allowed us to make a slimmer hood...The next size up supercharger, MP90 is much taller and therefore requires a significantly larger hood bulge. Something that we feel the majority of people would not have wanted. We understand that the hood modification was a little bit of a turn-off on our kit but was worth the performance of the Eaton blower. However, the larger hood bump required to clear the MP90 is pretty massive. For an example, here is the hood that we made to clear the MP90.

Some people love it...Some people hate it...personally I think it looks GREAT but, I'm pretty unusual most of the time haha.

Additionally, the MP90 was really, too much blower for the 3.5 liter displacement engine. In order to take full advantage of a 90 CFM supercharger you really need to do a stroker kit and make your engine at least a 3.9 liter. That way you have an engine that can actually handle all the extra air coming in.

Yep. Most of the 350Z supercharger solutions came in around 80 to 100 hp gain. Any more power really needed a built block to be reasonably safe. Sure, you could get plenty more out of the turbo systems, but that really required much more extensive builds though the rest of the systems to handle it reliably.

Kyle,

Just to be clear....does Stillen have something in the works for the 370Z in terms of supercharging?
