Topgunz - air to air upgrade

future370zzz

I made 436whp and 344wtq at 9.8psi using 91 Craptane on the Stillen water cooling system.

I would expect somewhere in the 475whp and 395wtq range (+-10) using 91 on the A2A system. PLUS, a whole LOT safer setup. 436whp is plenty for me right now, the safety is the biggest plus of the A2A setup.

With the 9psi pulley and the regular trim on the supercharger it will be around 460whp and 360wtq. But as stated it adds more than just power. Way safer, much more responsive and more fun to drive.

It also opens the door to take the kit up to 550whp safely, with more mods of course.

Late to the thread but couldn't find an answer. Sorry if it has been asked, but...how much work if any, would be required to fit this to a 350z HR? Looking at a used Stillen kit

TopgunZ

Nobody knows. It's never been done but I've been pmd that question about 6 or 7 times. I just tell them there's only one way to find out.

If your mechanically savvy then you can get anything to work. It might fit up, it might take minor tweaking, it might take a good amount.

The 8lb pulley overspins the sc though, right?

No. The 9psi technically does by a small amount. However there are several guys overspining it well beyond that even without a problem. I wouldnt hesitate to put the 9psi on.

Don't forget that they best way to go to 9psi is to change the drive pulley on the SC. You can order the 2.85 pulley directly from Vortec.

You will also need to go up in size for the idler pulley to get the correct tension on the belt. Still with the added idler it is way cheaper than what Stillen charges.

Just found the SC belt idler pulley that is needed when you go to the 9psi SC pulley. Use the NAPA 36112 part.

My kit arrived but few things to get still (haven't even unboxed it yet :O), need to get fuel system from Phunk and send my charger away to be upgraded

If we upgrade to Si trim + already have the 9psi pulley on and want more boost, which should we be getting?

I'm going E85 route so wanna crank it up a bit, happy to go around 15 psi

Doing the serp side pulleys will give you a bit more boost. Other than that, the only way you can get more boost is by going with a smaller sc pulley and overspinning the blower or removing your air filter. You won't get near 15psi though. I'd also keep in mind that boost works differently in a sc setup than a turbo.

It's a tough call between this and tt. 460/360 is good power, but I am worried that since the boost and power builds with revs, it's not going to be too noticeable most of the time except when I am pushing it which may make me regret not going tt. But it is so much cheaper than tt...

It depends on what you really want. It's perfect for a daily driver like me, since it's less strain on the engine and trans. I tend to stay out of boost on my daily commute, which is prob why I haven't had any issues these past few years.

wideglideleon

that's exactly why I also went SC.

brucelidat

I am worried that if I am only making much boost and getting much more power higher in the RPM range, I will rarely feel it since I am hardly up there in normal driving. Can you guys feel much difference in the 3k range?

I wish I could remember, but my car has been in the body shop for months, so my memory is a bit hazy. I'm going to say you'll only have 1-2 pounds at that range. When you want power, it will come to you and the power is very linear, so there's no drop-off.

Another benefit to the Si impeller that TopGunz mentioned is that along with the extra boost, it will kick in sooner as well.
