Hello all,
New to the forums and looking for info on the most reliable 300rwhp option for my 05 z. This car is a daily driver and i want it to last. NA mods wont get me close enough to 300rwhp without doing some extreme internal work. Already have a true dual borla exhaust and may go with the crawford headers. Any advice or am i just out of luck with a long mileage FI setup?

 

If your only looking for a little over 300rwhp then I'd suggest the Stillen Supercharger. Its one of the cheapest FI's on the market, and you get a warranty from stillen. It gets you about 325rwhp in Stage 1 I believe. If you want to up the power later then there's a stage 2, and stage 3.

 

325 rwhp plus warranty....agreed. No better set-up for long term.

 

Isnt the stillen a root supercharger with a hood mod needed? Im not to hot on ruining the lines of my Z although the root sc design is exactly what i think im looking for as far as engine characteristics.

 

Yeah, the stillen supercharger is a root design. You need to get the Stillen hood to make it fit. I know many people don't like the Stillen hood, but I persoanally like the looks of the stillen hood... its nothing too major, but yet it does set you apart while still keeping the lines of the Z. IMO the Stillen supercharger is perfect for the type of person that doesn't want too much power, but yet wants to get more power than he/she could get as NA, and spend a lot less money on the stillen then on NA mods.

 

thanks for the help im going to hunt down the hood localy and see it for myself before i make up my mind.

 

You also have the option of cutting your hood using their template, and attatching their hood scoop, if you don't want to purchase an entire new hood.

Personally, I'd just get the whole new hood, but just throwing that out there. Wow I just said 'hood' so many times it lost all meaning; ever have that happen? Weird.

 

Yeah im not cutting my hood and "installing" a scoop. How about i ebay my old hood and buy a new one that is actually one piece. I cant believe someone is going to spend 5k on a SC then cheap out and cut their own hood lol. Oh and stage 2 stillens are the only one with the engine warrenty so that is what i will be getting if i decide to take the plunge.

 

I thought Stage 1 had a warranty for sure, and I thought that stage 2 just recently got a warranty... I could be wrong though

 

FYI...Stillen is coming out with a new version of their hood to allow room for their SC kit. There's pictures floating around somewhere of this. Kinda looks like a Celica or the Kaminari hood with a vent located on the middle of the hood. Not sure when they will release it though...

Here's a small pic but there are better pics out there of this:

 

Doesn't Stillen have horrible customer service.... What good is a product/warranty (especially a four thousand dollar one) if the company doesn't stand behind it?

 

I was hoping that they worked with certain shops for the warranty and i wouldnt be going through stillen directly. If thats the case then you are absolutely correct xxlbeerZ. As for the stage one it does have a warranty option but it doesnt come standard with it and stage one has no intercooler so it really isnt an option for me anyways. Stillen has released another SC compatible hood with a scoop like the old mustang 5.0's and i guess that new hood is one too. Not a fan of either but i guess if i had to pick itd be the one with the scoop.

 

I would kind of like to keep my hood stock so people dont know what I have, you know a sleeper. Does Stillen have that much more of a superior system to justify changing your hood?

 

gatti-man, research before you make the plunge,if your set on Stillen(roots config.)I have a 1st gen stillen hood for cheap.
Honestly, after all the different s/c setups we have done I would look into centerfugel.Much more safe power with no hood change.

 

I suggest a Vortech, I have had several cars leave here that are every day drivers with vortech superchargers on them one even with 80,000 miles on it even and its still going. You will see more than 300hp most likely anywhere between 350hp-380hp on 8psi

The only reason I was suggesting stillen is that I wanted a low boost/low risk unit that offered around 300rwhp. The reason I posted is that Im aware of stillens bad rep from some people and wanted to make sure it was my only viable option for what I wanted. I dont want to cut or mod my hood. I do like the idea of keeping my warrenty but dang 80k and no problems on the vortech thats really impressive. Also researching FI is kindof hard since so much of what you find is opinion (sometimes informed and sometimes retarded) and not fact. The safest power is what im looking for, thats the aim of my thread anyways.

 

Devil's Advocate:

 

It would be nice if we had some knowledgeable people compare root (stillen) vs. centerfugel (Vortech). Someone said Centerfugel is safer, why is that? What system would provide safer power?

 

No,roots s/c systems are safer in a sense due to lower boost/ power. Centerfugel is as safe with proper tune and makes more power.

 

I think the theory was that the centrifugals are safer because they ramp up the torque as opposed to a roots blower where you are getting a big boost in torque across the entire rpm range. I don't buy this theory however because there are plenty of TT'd Z's that also provide a big boost in torque down low. If you look at the dyno charts on SportZ Magazine's downloads page from their supercharger shootout you can see the difference in the torque curves. If you pick up a copy of the current issue of SPEED magazine you can also look at the dyno chart overlay of the Stillen, Vortech, Greddy TT, and JWT turbo setup.
