Supercharging and HR
 

So, I'm in the market to supercharge my 08. I was looking in the direction of a procharger setup because I like the idea of the self contained lubricating system.... Now I'm seeing that procharger doesn't have an hr setup?.... Is this right?

I've done a little research on this and have a lot of experience on doing many different turbo builds as well as tuning on other vehicles, but I'm pretty set on trying my hand at supercharging the Z. So just a couple of questions for you guys... (Which I'm sure will lead to more)

1. What options for a self contained lubrication SC kits are out there for the HR?

2. Would a SC setup for a DE work and I would just need to fab up piping for the dual intake?( I think I was reading the timing cover and sc bracket was different DE to HR????)

3. What tuning options do you prefer with the HR ( I'm looking to street tune on the fly with a wideband if needed.. Nothing preloaded cause my home and nearest city are about 4k feet elevation difference).

Any constructive advice would be appreciated!

i think bigblue on here has a stillen sc, nismo0350 (i think) has a gtm twin turbo setup, there are not as many options for the hr as there are for the de.

^ +1. One thing, I didn't think Procharger made one for the '07+ HR's. I had looked into them 2 yrs. ago and they didn't then, only for DE.

About the Stillen (vortech blower), like Procharger, the blower is self contained lube. Stillen has a separate cooling system (electric pump); coolant reservoir to heat exchanger up front then to a small intercooler that is inside of the intake manifold for a final charge air cool down.

+1 on the stillen, it might be your only real option.

gtm, but they declared bankruptcy not long ago... greddy is another expensive option

The Stillen is good for about a 200hp/200tq bump if you upgrade it to the max. It was very streetable, and I never had a problem out of it. You can expect about a 140hp/70tq increase from the off-the-shelf kit as it is sold by Stillen, but with a custom tune. It feels like a faster N/A car from 4000 RPMs to redline, and stock anything under 3500-4000 rpms.

If you go that route, I would recommend buying the bare minimum from Stillen's kit, and getting a larger fuel pump, injectors, and upgraded impeller right off the bat. My HR ran fine for almost a year at 13 psi and around 430hp/330tq. My baseline dyno was 260hp/230tq before the S/C. I ended up pushing the kit for more power and broke a rod at around 16-17 psi and 475hp/375tq. At that point, the belt was slipping and the kit was pretty close to maxed out.

You can street tune with a UTEC

I haven't heard of UTEC on a HR. Is is supported? I have only heard of UpRev and Haltec.

So I guess my main question is.... Will the sc bracket and unit for a DE mount up to an HR. I don't mind fabbing up the plumbing for it

Stillen makes one for the HR if that's what he was referring to.

No.

OH HMM. I have a DE so no idea if it works with the HR

So maybe the next possibility is taking a DE single turbo kit and making some modifications to it..... Hmmmmm. Anyone know if the turbonetics single turbo exhaust piping would work on the HR? Or would it run into issues with the oil pan on the HR being different from the DE since the exhaust feed to the turbo runs down next to it on the driver side and under the AC.

I think you would have a whole lot better luck buying a 370Z turbo kit and making it fit. Same exhaust manifolds, flanges, and turbo placement. Same intercooler, MAF, and charge pipe placement. Talk to Boosted performance, AAM, or Fast Intentions. JTran can build you one, but they'd need your car for a few weeks.

I don't understand why you want to use a DE turbo or supercharger kit, why not buy a kit designed for the HR? Stillen makes a supercharger, S&R makes a single turbo, Greddy makes a twin turbo.

Yeah you're probably right.... I just like a challenge and I haven't had a fab project in about 2 years.

When did this happen? They are still operating to my knowledge!

Lots of 370Z Stillen kits for sale out there! Wondering what the differences are? If they can be made to work?

I see no advantages to a SC system for the HR over twin turbos. The only SC kit I know of for the HR is GTM, but we all know the issue with that. You give them your money, you may get the kit in a few months.

Power wise you will be more limited with a SC kit and these HRs have plenty of strength to hold a good amount of power.

S&R (now VSR) offers a single turbo kit for the HR. Greddy is upgrading their HR kit and will take some time but will be available in the future. GTM offers a TT and SC kit but, yeah, don't know if I'd trust them on that. AAM is now testing HR and needs test vehicles to install their kits. I would highly recommend this, as they make pure gold and they are working with new Warner turbos that seem to be the new bees knees of turbo. You are actually lucking out if you're getting into boost and have the budget for $10k or so. I've heard that's their price for installing and tuning a kit. It's one hell of a deal for their quality. Any comparible Greddy or GTM setup your looking at $15-$20k installed and tuned.

As for tuning, UpRev is known as the best lesser costing option, with the ability to purchase "tuner" software than can be modified through your laptop. What my opinion is on this, I'd not trust a street tune with these engines. Too many risk of running lean and shattering a piston.
As for wideband, you should tune for high 10s, low 11s. Anything over 12.2 is bad at full boost.
