Stillen Headers + Berk HFCs self-install report

RCZ · 04-02-2009, 12:58 PM

So whats next guys, since we are all going to have full exhaust and intakes soon...whats the next move... I am already looking at the stillen Pulleys....

I'm also looking at the Stillen pulleys. I guess after that it's a tune, as soon as UpRev gets their 370Z stuff ready. Maybe start scrounging around for enough coin to get set of Volk G2s. Oh, but before that, I'll be installing the Turbonator -- one into each intake tube.

I'm just kidding. Should be obvious that I'm kidding, but I want to go on record with that.

Edit: I haven't done the headers yet. I'll probably be putting that on my to-do list, pending the results you and wstar get. I've heard that it makes the exhaust note higher pitched. Not sure if I want that. So I eagerly await the videos once you guys have the full setup installed!

RCZ · 04-02-2009, 01:18 PM

Yup, on the record indeed

I am waiting on UpRev too. Wish Jack from HPLogic would chime in on the status of that.

wstar · 04-02-2009, 01:24 PM

Ditto on waiting for UpRev. This was an email response I got from them yesterday:

We're just now working on the VVEL motor cars. We should have an announcement shortly for it. The other solutions out there don't work yet, they may be able to adjust base fuel parameters and base timing parameters, but they don't have full or proper control on the rest of the ECU yet. We'll be the first to market as usual. Check our website for updates, and we can schedule you as soon as the software is ready.

Oh yeah, and TURBONATORS FTW!!111!!1

I'm putting 4 of them in each pipe when I put on my Gen3 Intake

RCZ · 04-02-2009, 01:29 PM

oh oh, looks like someone is going to ionize more air than you Ben.

ChrisSlicks · 04-02-2009, 01:32 PM

Don't forget the magnets on the fuel lines, that's good for 20hp right there

They claim up to 10hp for the pulleys but I'm guessing that number is when using a supercharger and you're trying to offset the parasitic loss.

Oh yeah??? Well I'm gonna stick them in my tailpipes to create a vortex of added propulsion. That alone should lower my 1/4 mile time by at least half a second!

LOL.

If you're running a supercharger you're not supposed to use lightweight pulleys, from what I understand. You wouldn't get enough power to the blower. So gains from lightweight pulleys are for NA cars. And I guess turbo'd cars would benefit as well (?)

I'm not sure I understand. If you're using stock sized (but lightweight) pulleys then the power delivery to the supercharger should be the same? If you change the pulley size then obviously that is going to have an affect.

I am just going to replace my engine with Chuck Norris.

Someone else could probably explain this better than me, but let me give it a shot. The whole purpose of underdrive pulleys is to supply power to secondary items such as the A/C. Power supplied to those items is power diverted away from the wheels (you can actually feel a slight loss when you turn the A/C on if you pay careful attention). Thing is, the pulleys usually supply more power than those secondary things actually need, hence there's room to reduce the amount of power supplied by the pulleys without negatively impacting the ability of those secondary systems to function properly. And the power that is saved goes directly back to power at the wheels. Now enter in superchargers. Superchargers draw their power in the exact same way as other secondary systems such as A/C. So whereas it's perfectly okay to divert some power away from the A/C unit, you don't want to do that to a supercharger, because then it'd be as though you're purposely handicapping your supercharger. Make sense? Let me know if it doesn't, and I can ask Josh to chime in with a better explanation.

Hey wstar and RCZ, you know what's conspicuously absent from our list? Lightweight flywheel. Do either of you plan to get one?

Thanks. Yes, I understand that under-drive scenario, but Stillen also makes lightweight pulleys that are identical to stock except for weight. I was wondering if they would net a measurable increase due to a slight reduction in rotating mass. I'm guess not, as the reduction is only 3.4 pounds which is nothing compared to the engine and flywheel, not to mention transmission. Obviously for NA it would be better to use the under-drive pulleys.

I suspect the flywheel is for 6MT only, I have an auto. For you 6MT guys, the lighter pulley and flywheel will give you a quicker revving engine when you're shifting. I doubt the actual horsepower gains under load are very noticeable though.

Check it out. What timing!
