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

[hover]

Can you post more about your setup? The numbers you are claiming seem a little higher than most hit. Thanks.

[SUPERCHARGED-JETTA]

Ya the numbers are there look at the trap speed 116.5 and i have been faster than thay already this year. Know anyone else running 11's in a corrado with 11.5 psi?

[hover]

I actually don't know anyone laying down 360whp with a V1 at 11.5 PSI, that's why I asked for more information about your setup. I'm really not trying to call you out or start some silly e-war, I'm just curious as to the rest of your setup that enables you to make and run those kind of numbers.

[slc92]

I don't doubt he's making some power but I would highly doubt 360whp on a dynojet for several reasons. One is the trap speed. Our cars weigh roughly the same. I make 274whp and trap just under 113mph. 85 more whp and only trapping 116.5? I don't think I've even seen a VRT get close to 360whp at 11.5psi

Jettset made 300whp at 10.5 psi, IC, short runner, 3" exhaust
Throttle made 286whp at ~11.5psi, non IC, cams, 2.5 straight through

Where is the extra 60-75whp coming from? If I had to guess that car is making between 310 and 330 whp on a dynojet. That's based on the setup, trap speed, and weight. Not hating the setup either by the way. It just doesn't add up. AWE tuning has a Mustang that dynos high so I think it depends on the dyno.

[SUPERCHARGED-JETTA]

My car was dynoed on a mustang dyno i was told to add 15% to get dynojet figures. I guess i wont know for sure untill i dyno on a dynojet. So if that helps everyone good, I just want to get deeper in the 11's

[MR 2.GO]

I met a guy @ show n go lastmonth had a yellow gti his name was Rob didn't catch his vortex name but he claims he has like 400hp or some highnumber around ther don't remember the exact hp but I know it was more then iv ever head with a SC.... with a V9 and I think he said 2.75 pully... wat do u guys think about that?

350whp is def doable. A friend of mine did 350-55whp. BUT, it was on a mustang dyno so he's goin' back on a dyno jet. Don't wanna give his name away. I'll let him bring the news in

[turbo mike]

330whp my friend...but i dont trust that dyno nor do i trust that it was setup right, therefore i will dyno again on a dynojet.

rob(yellow gti) i think i sthe guy i just met last week friday when i ran my car. hes not going to make anywhere near 400hp with his v9 and the setup he has. he ran high 13's all night iirc, with quite a bit of "work" to the motor.

says he has more plans, til then, ill wait and see.

[VRC-YA]

AT least we can finally put the myth behind that 300whp is impossible with a charger!!!

[SUPERCHARGED-JETTA]

I know my car is makin power just lookin for more all the time. I may just up the boost a little more

true, but there are a few guys that have done it a long time ago...theres just more of then now.

[CorradoMagic]

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

[b5vwc]

Thought i'd add the Rotrex Supercharger to this thread...

Max Boost: 17psi
402.4hp at flywheel ~345whp @6676rpm, 135.3mph
330.5lbft torque at flywheel @5960rpm, 120.8mph

Setup:
Rotrex C30-94 85mm Pulley
Schimmel Shortrunner Intake, A/W Chargecooler, 263 Cams
Schimmel Head Spacer 9:1 Compression, ARP Head Studs & Rod Bolts
Forge Split-R Dump Valve, 95mm MAF Housing, BMC Air Filter
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

Exactly what I think of every other claim. Show me a timeslip or a dyno. Everything else is speculation. Highest V9 I've ever seen on a 12v is 300whp. 2.75 pulley makes 8psi on a V9 which will run high 13's in a full weight car. 400whp is BS.

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.

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.

i did that as well. check your cam timing, it may be off a tooth. ive been told by the all motor guys that the schricks dont sit 100% like they should. i put mine a tooth advanced, and im at 16-17in at idle.

and make sure you dont have vac leaks.

[SUPERCHARGED-JETTA]

Hey guys i did some searching around and it looks as if the difference between dynos could be anywhere between 10-15%. So if thats the case then 305whp mustang could be 340-360 dynojet.
Here is a video of my dyno.

throttle- i went balls deep in this engine. i checked timing and all the marks lne up.
which cam did you move and what direction did you go. my proble is i beyond lazy, i stopped when i saw all the marks line up.
but im selling them, i dont care at this point. (im gonna turbo the other gti for me and leave the s/c car for my wife)

[turbo mike]

my flywheel mark sline up with the bell housing, and the cams were just a hair off. if you look at the ends where the cam tool would slide in, the were tilted back just a tad. i moved them one tooth forward, and it cleared up the vac issue.

its not going to make a huge difference imo, but its something worth trying.

if you sell them though, its not worth the work to just pull them out later.

I thinks it's really hard to use a calculator to determine what you'll make on another dyno. Mikemcnair made 177whp on AWE tuning's Mustang with only a chip, intake, and exhaust. That's about 10 whp high for a Corrado w/ those mods. I mean do we really think his car made 195-205whp w/ I/C/E.

Again, you are making great power and great times. I would be interested in what power you would make on a Dynojet. They seem pretty consistent from dyno to dyno so I think perhaps better for comparisons to other cars. I've seen Mustangs dyno high and low.

[websaabn]

I cant wait to get the Wifes car on the dyno and see what it can do.

mods
-autotech 262 cams
-vortech v2 charger with 2.87 pully
-c2 36lb s/w
-c2 dual idler
-accel coilpacks
-snow performance w/m injection
-vortech mondo bypass valve
-custom dual 2 inch downpipe
-full 3 inch exhaust with high flow cat and borla xr1 muffler
-ported & gasket matched exhaust manifolds
any ideas what Whp it should put down ?

[slc92]

How many psi w/ that pulley? If it's 11-12psi I'm thinkin 300whp.

yeah, about 12psi. so if fueling is right, 300whp is a good estimate

[SUPERCHARGED-JETTA]

That bunny should run pretty damn fast

[websaabn]

I am hitting 11 psi with the 2.87

Pretty much the same setup I have except for the W/M injection, 3" exhaust, and you are obd2 which usually make a little more power. I would expect ~300whp if it's tuned up, good A/F ratio, and tuned w/m injection.

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

[speeding-g60]

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

96 VR6 GTI. Vortech V-1 S-trim stock AMS kit, 8.5psi. 265WHP. only other change motor wise is an EIP manifold....

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....

some pix...

[slc92]

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
