6 psi, right? Not bad at all.

Nice dyno, I bet its a blast to drive. Enjoy!:D

Awesome numbers!! Congrats!!

Congrats

do they use the v2sq blower? don't know if they would sell the themoplastic by it's self.

Damn his 6psi makes more whp then other 7psi kits, by a good 10whp.



edit: then again, he does have stromung exhaust...

nice.. polished blower looks mint. The tunning looks good. :thumbup: enjoy

The AFR line shows the secret ingredient of VF's power...high 12's and close to 13:1 AFR near redline. Which ain't particularly dangerous at that boost level, as long as the timings are modest and the fuel is good. But there's NO margin for running cheap/lower octane gas, and there's no margin for a quick boost bump via a SC pulley swap.

That's about a point or more lean than a stock Dinan tune, by comparison, and can account for 10-15 rwhp all by itself. Combine that with a bit more aggressive timing and we can see how VF is able to out-dyno the other Vortech base kits at lower boost pressure. Just keep it on the good gas and you should be fine.

how about my '95 w/ a 6psi VF s/c?

hamada, lookin good man! go have some fun w/ that thing :buttrock

Nice numbers! :buttrock

I can't wait to see some s54 dynos. I'm sure GIAC will blow away the competition there too.

nice numbers! Make a video :cool

yup stage 1 = 6 psi

Yes this is the v2sq blower. You can ask them I am not sure.

Actualy Nik called me earlier this morning, that 13:1 up top will be tuned on Monday. Apparently they need to adjust it and add more fuel up top. He wants perfection.
They seriously go into the smallest detail throughout the install. The blower and the whole kit as a matter of fact looks and feels very solid. I was pushing on the blower..that thing is solid and would not move.

Congrats on the numbers!
But I have a question for you, you say that you are going back to get your afr's tuned. Does this mean they will be modifying the software? Because I'm interested in this kit, but I was under the impression that its basically bolt on. I don't want to have to send back to get a new tune on the chip. We really need a bmw tuner in edmonton :(

Thanks

nice! will you do stage 2 soon:stickoutt ? how much will you put down for stage 2? do you have an aftermarket clutch, if so what?

Glad to see Hamada is pleased with his kit. We are revising his software which will be a revision sent to all existing customers. It is not usual for us to ship a revision but we are in this case.

So far, out of the dozens of E36 S52 kits shipped only a handful (3 to be exact) of users will be affected. We are covering the to and fro shipping of their ECUs.

Hamada,

It was nice chatting with you at bfest. finally an affordable way to get some power out of our cars huh? :D

Nik, glad you guys are staying busy over there, i wish you guys the best! :buttrock

how's the noise level? can you tell there's a SC when you're under 3500 rpms? does it sound civilized (quiet) or like tie fighter defending the death star?

mine's going on soon too :) I have the zionsville+Spal combo. noise-wise it's going to freak people out when they all kick in together. VFE pls. check PM I just sent an inquiry about E10 gas.

How does the bypass valve sound? Does it sound similar to a blow off valve? Does anyone know how much stage 2 will cost? Also, did you change your clutch yet?

Very classy looking centri system I must say. I really like the look and the power output.

I added this thread and VFE to the list! The BMW FI List (http://forums.bimmerforums.com/forum/showthread.php?t=521046)

Interesting that people have pointed out the fuel is running lean.
When I used to be active on VWVortex, GIAC was known for running lean and causing occassional pinging on the VR6s. Hopefully everything will be sorted out with the revision :)

What's the status on getting CARB certified? Always been interested in VFE, especially only being a 15 minute drive from me.

The noise level of course will be relative from one person to another. To me, it is quite at idle, BUT you can still hear it. I think it gets quiter at may be 2500 up. Overall I am happy with the noise level. No complaints there so far. I need to keep on driving though as I am still getting aquainted..:D

What does the bypass valve sound like? does it sound like a blow off valve? are you still on the stock clutch? if not, what clutch do you recommend. thanks

I also just posted in another thread, but is feedback on my E36 M3:

I just had my VF SC installed on my '98 M3/4. It took about 2 days for the Dynospot racing guys to install it. I also just found out I'm ready for a S/W update so soon. Don't know the details, but I'll let you know as soon as I find out! I was told by the Dynospot, there were no modifications required, but I also understand I was first to get the VF SC with OBDII. I thought these units were installed by alot of folks from what I seen at bimmerfest this year.

First impressions are Vortech SC is noisy at idle, but beyond 1200 RPM's it has the nice whirling sound. The SC noise at idle is like what other folks claim.....marbles rolling around or grinding. Definatley louder than the engine and can be heard inside the car. I have the V2 model. There is no SQ after the V2. I called Vortech and they claim that is normal at idle. But I am still unclear if I have an SQ or SQ trim, etc.

I'm not too happy with the loudness of the SC when at idle, can other folks with a Vortech V-2 chime in on the noise it does or does not produce at idle?

The upside is a noticable increase in performance beyond 3500 RPM's Wow!!! I had a little run with a Mitsubitshi Evo and gave him a run for the money. LOL.....

Mine sounds exactly like the estoril M. Definately not as loud as the silver one. I'll try to make a vid sometime this week.

I was just at Dynospot as they just completed a 2nd M3 VF SC installation. It sounds about 50% quieter than mine. So there is some variation from SC to SC on noise. I just hope that mine gets quieter looking forward as it has been getting noisier at idle during my first week. We have the same exact VF SC kit on our M3 '98.

there's no sound made with the bypass valve in a SC setup.

my car for now is zero rwhp..since the blower is being repaired...as for the rwhp prior....nothing to brag about...it's in the tuning process.

I checked with Nik today, he said the stock clutch should be OK. I might go to the e34/M5 clutch and UUC light flywheel steup tho.
hamada

you can hear a slight sound when letting off boost. It is tainted though nothing extreme. Damn Hung your car is loud. :wow Mine is either quieter or the same as Kobe's.

five3five order the performance organic setup/stage 2 LTW flywheel. Its a notch above the M5 one and yet feels like a stock clutch and can withstand more power if you choose that route.

well...
the noise gonna change after this...since my blower will be brand spanking new w/ new bearings and seals.....

If youre blowers are getting noisier, even with blowers in good shape, they will make more noise with age. I had the Vortech minor rebuild at about 60k accumulated miles, and since its been back, its as quiet as when it was brand new. A noisy blower doesnt necessarily mean a broken blower, but its good to know that this rebuild srvc will take care of it in at least some situations.

that first dyno graph does look a bit lean. if they used a tail pipe probe they generally show about .5 richer than it actually is so you were definitely running on the lean side. lean is definitely meaner!

Richer or leaner? Below about 4k rpms, there is still some residual O2 in the Cats, which I thought would tend to show a Leaner result, because of that O2. I also believe the Innovate literature says the same thing.. tendency for leaner, not richer readings.. However, At WOT above about 4000 rpms, Ive found most tailpipe sniffers to jibe well with the pre cat wideband because that O2 tends to get scoured out.

Very, nice enjoy !

I just had the latest and greatest from VF Engineering put on my 97' 328is. The newest blower is the SQ V-3 which is so quiet even the trained ear could easily not pick up on the barely audible whistle it makes just off of throttle. I know that the old "marbles in the bowl" sound that these blowers made at idle was not many people liked. But this new blower has addressed that problem! I have only put about 400 miles on it since install and I plan on getting it back to Carb Connection here in the Nortwest for another run on the dyno. I am hoping for 285 WHP or close and this is at 6 PSI. I will say that at 4K the car really comes alive and pulls very hard right up to 6K+. As for the tuning I am glad I went with VF the car drives just like stock except with alot more power. There is NO ill side effects whatsoever from the blower install.

Feel sad for me????? What does that mean??? Maybe it is not the fastest set up out there maybe it is not what you would have gone with. Regardless I feel that for the money it is a great S/C. I spent over 3 months trying to decide between AA, RMS or VF and at the end I went the way I did. Like I said I could have got more power for my money but I am not a street racer or anything like that and wanted a car that drove like a stock car. I read too many other posts telling of stories about tuning issues with RMS and AA. And since I am in a wheelchair and paralyzed from the chest down I am not able to work on my car like I used to before my motorcycle accident. That is why I chose what I thought would be the best hassle-free S/C currently offered. Putting everything else aside at least I can say the VF system does live up to the claim that it's software makes it a vast improvment over stock with no temperment.:pikachu

Man, I am jealous of the internal oiling system. My V-2 leaks a little and I hate it.

I just got off the phone with Vortech, and its 2400 bucks for a v3. They also stated they do plan on doing some sort of a trade up thing in the near future no exact date yet. I think I found my next x-mas gift.

Well good luck and let me know if you need help

Man, I am jealous of the internal oiling system. My V-2 leaks a little and I hate it.
The closed internal oiling system is nice the only drawback is that VF will not tell you what type of oil they use. I had to wait an extra day while I had 3 small bottles "Next-Day" air shipped to me. If you run anything other than their oil it automatically voids the warranty. The guys at the shop came up a little short on oil so we decided to leave the car parked. Like I said VF would not tell us what it was I can only say it looks like regular Torqco Synthetic oil. The little bottle are like 6oz. each and three cost $40. Fourtunately VF says after the initail change at 2,500 miles it only needs to be changed every 7,500.

I wonder what cools the oil? I almost prefer the system I have knowing it is hooked up to an oil cooler.

Good point.

That's only if you install an aftermarket oil cooler on your car. On mine it wouldn't make a difference.

Perhaps the V-3 has improved bearings that don't generate as much friction (heat) and are easier on oil. <--Just speculation, but why else would they go with an internal oiling system?

I spoke with the guys at the shop and we discussed this point. From what he told me VF is staying pretty mum about the blower in general. I did ask him if he thought if ceramic bearings were out of the question and he said that it could be a possibility. The SC does not get that hot so between the oil they are running and whatever bearings they are using VF has decided that cooling is no longer an issue. This SC is the one that goes on the new C6 Vette so I am sure whatever it is they have spent many hours testing before releasing it. It also still comes with the 3 year unlimited mileage warranty!
