*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.

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.

This is funny. They changed that for the V9 F within the past year. It used to read 60K efficient max, 65k absolute max.

Might have something to do with all the V9 F's they have had to warranty from VF.

I think I could pick up another 20whp if I did a a BVH w/ P&P and a larger DP.

[turbo mike]

if you helped it flow out faster, i wouldnt doubt it. but the money, imo, isnt worth the gain. not unless youre trying to be the highest hp s/c vr out there type of deal. i thought about doing it, but the amount of money id spend just wasnt worth it to ME...

youre making awesome power as it is. id love to see dynojet numbers rather than mustang, just to compare the two dynos since you know your car is consistent

Walbro Fuel Pump, Delphi 440cc Fuel Injectors, Weber Fuel Regulator
Custom Map on standard ecu, 2.25" Exhaust (to be upgraded)
Peloquin LSD, 3.68 Final Drive, Limiter set to 7268rpm

I had a Vortech V9 on this same setup but the Rotrex is another level, quieter and smaller unit but kicks out some serious power and much better torque... no belt slip issues

Rotrex . I was doing some reading on those S/C's and they have damn near turbo efficiency. I really want a MK2 VR with a Rotrex on it, maybe I should sell the DD and have 2 "fun" VR's haha.

Good points. I'm at a point now where I'm thinking long and hard about upgrades. I could swap in 268 cams/springs, water/meth inj., and a full 3" custom exhaust and probably hit 300whp but that's ~$1500-$1600 for 25 more whp. I could probably sell the kit, add that $1600 and make 400whp by going turbo. I would ultimately like to run 11.5's in a full weight car and I don't think you can do that in a SC VR. At least I haven't seen it. You need more than 350 wheel for that

Alot of good info in this thread.

yeah its all about air flow. Unless my DP breaks or something else goes (or I win the lotto ) I dont see myself doing these additional mods. I'm pretty happy with the current set up. However, it does occasionally run out of fuel around 6K rpm. Jeff says its the injectors(they're maxed out). I think a 4"Maf w/ a 36# tune would have yielded a few more horses up top & given me the ability to keep in the redline area a bit longer.

I think water or W/M may be a new project

I am quite curious to see the Dynojet numbers as well. I would guess 327

My friend built mine, and i ended up with the car...

the car was charged @ 20k, its now right at 131K..... with no rebuild, it runs real strong. pulls hard, and is a totally fun driver. i do not track this car, as i have a ~525WHP 20vBT rabbit GTI that is my drag car. the MK3 is more setup for road driving... PSS-9's, Quaife, BBS RK-II's, Autotech big brake kit, Autotech strut bars F/R... just a blast to drive....

How are you getting 15psi out of a V9? What size is the pulley? The one in the pic is purple and looks like the 2.7" VF stage 2 (8psi) pulley.

You would need a ~1.5" pulley to see 15psi out of a V9 and one of two things would happen. 1) The charger bearings would fail as it's spinning at it's max w/ a 2.25" 2) You would get alot of belt slip.

15psi from a V9 w/ an intercooler Sorry, I call BS

[turbo mike]

keep in mind, not all 15psi pulleys work the same on different chargers. my 2.87" pulley gives me 12psi, but it wouldnt produce less on the V9 iirc....steve can correct me on this if im wrong.

[dasGolf01]

Anyone have issues routing their v-belt on a Stage2?

I'm finding the belt is super tight fitting, having a hard time getting it over and then being able to tension it.

Right now with total slack on the blower, the belt will almost get over the pulley but not quite, so I'm not sure I can pull any tension into the blower once I get the belt routed.

VF thinks I just don't have it seated right as Stage 1 and 2 have the same belt, but I need to be able to tension the blower some to get the oil return line past the alternator as well as the discharge pipe up some to route it to the piping.

Thanks

[turbo mike]

ive been told by a few and also learned from experience. the belt should be tight when its new. if youre having trouble putting it on, youre good. my belt is a pita when new, and once its on and running for 30 min, it loosens up a lot. get it on, put tension on it, run the car for a bit. then tighten the tension some more.

[slc92]

The power steering pulley should be the last one on since it isn't ribbed. You also mentioned intake piping. A V9 charger can be "clocked" easily. The large V band clamp that separates the two halves of the charger can be loosened and the two charger halves will rotate. I loosen that clamp every time I tension the belt so the intake piping/outlet of the charger stay in the same position while I tension the other half of the charger/belt.

Loosen the band clamp, loosen the charger al the way, route the belt, and put it over the power steering pulley last. It is tight though.

It seems like the same size pulley on a V9 gives you about 2/3 of the boost of a V1/V2. However, it seems that V9's have less of an issue w/ belt slip as well. V9's don't seem to slip even w/ a 2.25" pulley and single idler whereas V1/V2's slip alot w/ a 2.5" pulley and dual idler from what I have heard.

No way. Your gauge is off or you are revving over 7200 rpm.

Vf stage 3 uses the 2.25" pullley and sees 10-10.5psi intercooled.
You are seeing 11 psi w/ a 2.62"? Nah. That's an 8psi pulley w/ IC at most.

great thread Im trying to get through all of it but havent made it yet. Question though.

Im soon too be running a 2.9L vr6 with an Ams vortech V1, with an 8 pound pulley and no A/c. I also have the idler, I need to know what size belt to run please help thanks in advance.

[CorradoMagic]

the 2.5" pulley is advertised as a 15# pulley by certain places. However, that is based on a V1/V2 charger @ an undisclosed rpm.

I ran the 2.5"/15# pulley w/ dual idler on my V1 setup. I never came even close to 15#. The V1/V2 chargers are larger & have more rotational mass to move than the V9's. This results in increased belt slip. If you were lucky enough to ever see 15#, it wouldn't be very consistent.

Cogged Pulleys FTW
Its a trade off. the V9 seems to spins easier & w/ less slip & also has a higher rev. point (65,000rpm IIRC) vs the V1 55,000.
Although the V1/2 push more CFM.

A worked head/exhaust etc w/ a V9 & no belt slip can be a very nice setup.
Big numbers should be left to turbos. Solid performance and smooth power delivery are what the SC is about.

The AC pulley has ribs that can be shaved. This will increase belt life by not having its backside run along the ribs.
The ribs on many non Vortech pulleys tend to be very sharp. When over tightening the sharp rubs tend to 'slice' through the belts. I ve been there, done that.

[ThaCorradoKid]

so are pullies interchangeable from V1/2 to V9's?
