      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 [IMG]http://**********************/smile/emthup.gif[/IMG]

      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.

      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

      Rotrex [IMG]http://**********************/smile/emthup.gif[/IMG] . 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.

      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)

      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.

      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 [IMG]http://**********************/smile/emthup.gif[/IMG]

      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 [IMG]http://**********************/smile/emthup.gif[/IMG]
      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...
      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....

      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

      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.

      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

      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.

      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.
