*The unofficial VR supercharged reference thread* specs, setups, et cetera

[hover]

Alright, while this is the FI forum, loads of the talk and info in here is about turbos. Searching through the archives and various conversations via phone and IMs leads me to believe that there are more supercharged VRs in here that one would suspect. Also, for one contemplating a supercharger setup for their VR, information is not nearly as accessible as information about turbocharger systems.

So. Here's the rules:
Post what setup you are running.
-If you've changed pullies, gears, whatever, please post that as well.
Post any dyno reuslts you might have.
-If you have changed your setup since the dyno, please post your setup at the time of the dyno.
Post any track times you might have.
-Dragstrip results only preferably, as not everyone can compare road course times or autocross times on different circuits
Post any information you have that one might consider useful.
-Feel free to IM me with other links and information as well, and I will add them with credit to you.
No nudity.
No OT turbo BS.

Hopefully, we can get a thread going with some good information in it, and maybe get it added to the FAQ.

*Also, this thread is a work in progress. If there is something you feel should be added, be it a link, book, or another site; please either post it or IM me, and I'll add it. This thread is intended to reference tool for all of us, and especially the new people looking into supercharger systems for their VR.

Thanks for your contributions.

Supercharger kits available:

VF Engineering is currently the only producer of off the shelf supercharger kits that are available new. These kits use the Vortech V9 blower.

C2 produced supercharger kits for the VR. They do not anymore, please don't call Chris and ask him if they still do, if they have any extras laying around, or if they are going to put them back into production. They don't and they aren't. These kits used the Vortech V1-S or the Vortech V2-SQ blower.

AMS also produced a supercharger kit. This was another Vortech based kit that used a V1 blower. I'm still researching more about this kit, and will edit the post with more information later.

Z-engineering's did not use a Vortech unit, but their own supercharger instead. Most people's complaints about the Z-engineering kit were directed towards the software.

*still working on completing list, please IM me with details on what I have left out. I know there are a few that aren't on the list. -Chad

Four Season Tuning, a very reputable business is now catering more to the SC crowd. They have brackets, belts, pistons, DVs, pretty much anything you could need, along with a whole slew of other things that we all just want. Thanks Guys.

room for expansion, still a work in progress.

Although I am adding information as I can to this thread, all contributions and discussion, as well as any information you have about your setup is more than welcome in the thread. I know enough to know that I don't know it all. Some weighing in by those more knowledgeable and experienced with supercharging the VR would be great.

Thanks.

02 12V VR6

Just purchased a Stage II VF kit as well as a Samco hose kit, new crack pipe, thermo housing and all parts attached, phenolic spacer, dropped in the NGK BKR7EIX plugs and converted the coilpack to MSD coils.

Crack pipe, phenolic spacer and thermo housing are in. MSDs are wired up and will be put in once the other stuff is here.

Just waiting for shipment to arrive.

Great thread, I'll post up pics once I start getting the charger in there, as so far, just looks like a torn up engine bay.

[hover]

Been sick, haven't added much, so here's a bump. Still waiting for others to chime in.

[gannonjf]

Agreed, more info would be great. I'm pretty sure I am going to go with a charger rather then turbos so I'm doing all my homework now while I wait for money to collect in the bank

[hover]

Anything you are looking for specifically? If so, I can see if I can help find it, and maybe add it to the thread.

I would like for this thread to be a resource for those thinking about supercharging theirs cars, and even of use for those who have been around for some time.

[dasGolf01]

Info like different plugs (I went with the BKR7EIX) and if the oil weight should be changed, does it need more with the charger on it.

Maybe if there are links to any info on the installation of this stuff as although my kit is on the way, I'd like to know what to expect when it gets here.

Anything like that would be great.

[Grits 'n gravy]

Z-Engineering uses their own chargers, not vortech units.

[Noobercorn]

wow, this is a heck of a thread. good stuff. perhaps sticky material?

[CorradoSLC]

I have an OBDII Eurotech V2 kit. It runs the 4bar FPR, ~8spi pulley, V2 SQ charger, and colder plugs. Understand the P.O. put down 245whp several years ago.

Relevant info: uses K&N RC-3180 intake filter directly on the charger (appears to need 5/8" vacuum plug on the end of the filter)

Currently uses Bosch F6DTC plugs; interested in trying NGKs the next time around

Current dyno pending...

[Noobercorn]

i would like to see pix of your setup please.

[CorradoSLC]

voila

Not nearly as impressive as your SLC setup from what I hear, but fun as a daily driver nonetheless

[Noobercorn]

any close ups of the compressor side? what software are you running?

thanks for the pic, and compliment.

[CorradoSLC]

That's really the only engine shot I have, unfortunately.

Software is a Eurotech OBD II chip from back in the day. By all accounts it shoudn't work (stock injector capacity, MAF after the charger, etc.), but it does. From fun runs to driving my son to daycare every day.

Need to get it up to NGP for a dyno run one of these days, but maintaining two SLCs in addition keeps time and money short.

[dasGolf01]

Nice looking setup, Corrados are sweet and yellow, even better. Once my kit gets here and I have it all slapped on, I'll have pics.

Anyhow have an answer to change in oil weight or amount? Just so I can be prepared for when the kit gets here.

Thanks!

edit: That's not a rado, sorry.. just looked at the body.. made an assumption from your SN.

And yours is the car I'm waiting to see the results on. Very similar to one set of the plans that I have for the Golf. Only time will tell what happens of course, but I'm thinking of doing the same cogged pullies, a V1, and a few other things.

[Acri2903]

96 gti

- 12v vr6 from mkIV
- v2 polished charger
- c2 software
- 8 psi pulley
- stock injectors
- has p/s, no a/c
- neuspeed catback
- arp hardware
- kinetic headspacer

no dyno or track numbers for me. i just enjoy driving

car runs great and is very daily drivable with this setup. def. fun for those who don't need gobs of power all the time.

[CorradoSLC]

Thanks...the original owner took great care of it and did all the hard work.

For oil, I use 5w-40 Elf synthetic, and change it every 6mos or 3k (I don't put that many miles on it). Same amount as stock.

[dasGolf01]

Awesome, thanks for the tips and info.

I'll be ready to flush/pull the oil pan when tapping it for the return line.

At least that's what I'm guessing I'll have to tap the oil pan for (like I said, no installation instructions out there pre to getting the kit, just what I've heard of and such, and I'm not sure how much different the MKIV is from others.)

I wouldn't say that it shouldn't work. Yes in the C2 era post blower MAF's and stock injectors are frowned upon, but many companies used those combo's when vr's started getting blown, and they have been proven.

I was having problems w/ my old ecu or chip (GIAC 30# obd2) and i sourced an AMS tuned ecu from the OG kit, and threw the stock injectors back in. thing runs like stock, still pulls pretty damn hard too. I do get some timing pull way up in the rpms, which may be due to leaning out, but the tune is still really good. I'm sure some fpr tweaking could get it to a happy place.

I'm going to be trying an ATP 30# chip soon, also a post blower maf file, which I've heard has put down pretty good power, and great driveability.

I'm:
AMS kit w/ a V1 (rebuilt)
OBD2 swap
Neuspeed 60mm catback
passat 3.38 box
"stock" 8psi (can see 10 @ redline) ams pulley

thinking about dyno'ing these changes for info, but like my man above, I'm all about enjoying the drive, and not concerned w/ #'s. I think its a common theme w/ s/c peeps...

Some V9 8.5psi A/F & Dyno numbers, pulls were done on EPL's Mustang Dyno.

[CorradoSLC]

Yes, you summed it up better than I did - I completely agree with you...if it works, it works.

The main reason I'm interested in dynoing (okay, aside from curiosity) is to check the A/F ratios. My in-car gauge always shows rich under boost, but we'll see.

Either way, it is definitely fun with the blower...

[dasGolf01]

Still waiting on VF to get my kit shipped to me, could show up Friday, could show up Monday, of course then I'm out of town from Tuesday until next Monday. Have everything else buttoned up, though. Phenolic spacer, new coolant stuff, starter fix, bunch of other maintenance, dying for my ride to be alive again. Waiting sucks.

CorradoMagic's numbers are in..... 300+ WHP with a Vortech SC.

[dasGolf01]

Anyone here running the MKIV 12V S/C? I was mounting the charger yesterday and wasn't able to detension it enough to get the belt on. The drain fitting/elbow bumps my front chassis pinch weld before it can detension completely.

Any ideas? Or should I just try to... pry the belt on, as it were. I'm afraid of damaging the belt, though.

Anyhow, the wiper reservoir is relocated and dripping in one spot, have to seal up one place.

PSR is relocated and that was easy enough.

MAF is relocated. MAF Clamp is wired in there, but haven't wired in switched power or ground yet until I figure out where I want to place it.

Injectors are in and fuel rail is back on, had a lower intake manifold bolt shear as I think my torque wrench failed so I'm waiting on a new one of those before I can get the upper intake manifold on, the front clip back and then start fitting the charge piping and what not.

I must say I'm not horribly pleased with having to tap the block, thought it was the pan, but apparently not. That's the next step today, though. Drop the pan, tap the block, route the drain and feed hoses and see if I can get the charger set again and the belt on.

Any help or advice would be highly appreciated. Cheers

edit: I think they sent me a belt that's too short as I finally got the belt on with absolutely no ability to "tension" or move the blower. Anyhow, will call VF tomorrow.
