      Yep, we've got several fuel rails under development or finished already. The Mk2/3 VR6s are done and feature -8AN feed and -6AN return ports. These parts aren't difficult for us to physically produce. However, I'm slammed at the moment juggling other projects. We can do the Mk4 VR6 stuff, too, but I need a car in front of me to measure, etc. [IMG]http://**********************/smile/emthup.gif[/IMG]

      Thats great news!!! Will these new VR fuel rails be able to flow big amounts of fuel for us big power, drag guys? Any ideas as to when I could get my hands on one of these rails?
      I was looking to buy some injectors from you but I think I will hold off untill I find out more details behind the new ones you will be offering. Thanks for the info as always .

      Andy, which VR6 engine do you actually have? It is the Mk4 VR6 engines (12v, 24v, and R32) that will get the new injector treatment (along with the 1.8T variants). As for the flows... it's all about BIG.

      To feed that hungry engine on pump fuel I would use 440cc injectors. Combine that with a strong inline pump, a stock 4bar fpr (or adjustable), and some quality software and you'll be good to go. Standalone management will offer the best power and reliability

      ok what do you suggest i get. my mechanic says that he would put a haltec ecu i believe its the F10x which he is charging me $850 for and 440cc injectors for $54 each. i can get the ecu for $730 i just would like to know the prices you offer that way i wont have to scrounge from place to place looking for parts. so i believe i would need the ecu, injectors, 4bar fpr, pump, anything else? please pm me a price so i can haave a rough estimate and anything else you believe i would need to achive my goal.
      thanks for your help,

      Frankly, for as "little" as 300-ish whp I'd just go with a chip. You might give up a few hp, but the refinement will be there. Once you're shooting for more than 400whp I'd consider standalone a no-brainer. Anyway, I just shot you an IM with pricing information and such.

      hi, i have a 1992 2.8 vr6 (dizzy) which i am about to add a z-engineering supercharger with 8 psi pulley, my engine is stock apart from a cone filter and straight thru exhaust system and a 4 bar FPR. im looking to run in the region of 250-280 whp and would like info on chip choice but mainly what size injectors i should run and possibly the part #. thx very much..................

      Hey i am looking for some expert input on some fueling questions...
      going to be running a 16vT...aiming for 300whp..looking at going with 034efi standalone.
      what size injectors should i look at getting and what about FPR (rising rate or just a 3 or 4 bar one?) and can you give me a price shipped to canada please

      Sorry for taking so long to get back to you. I'm on the road right now in Stockholm, Sweden. Internet access has been a bit spotty. Anyway, my recommendation is to go with whatever VF Engineering's software calls for. Alternately, you can do well with a chip from C2 Motorsports. With that said I'd probably go with some 315cc. The C2 chip calls for 380cc, though. I've got whatever you need. Just ask.

      Okay, a 300whp 16vT, eh? I'd grab some 580cc low-impedance and run them at 3bar. That'll idle very sweetly with great high-rpm accuracy, too. Plus, you'll have plenty of headroom for making more power later. Please check your IM for pricing!
      Okay, off to Copenhagen, Denmark I go. I'll be back in the States in a week, but can take care of orders right now, too. Later folks.

      hey Scott,
      I'd like to know what injectors i need for my engine.It's a 1.8t AEB T3/T4E, Autronic and, adjustable fuel press. reg.. What base psi?Multi nosel or signal nosel? Low or High Imp.?My HP max out-put is 300,but for every day 225. Would like a smooth idle. Your expertise will result in the "randiest" car I'VE EVER SAW, DRIVEN, AND HAND BUILT. Thanks really Hope your trip was fun.

      Okay, since you're using Autronic you have plenty of options. You don't need all that much injector to support 300whp. So, I'd suggest my new-style 415cc (with the proper 1.8T spray pattern). Run them at 4bar and you'll be good to go. Your idle will be factory-smooth, throttle reponse will be sharp, and emssions will be clean. These injectors are high-impedance, have a single spray nozzle, but have multiple orifices from which the fuel is emitted.

      I'm not sure if you're asking a question or just sharing your spec. But, those injectors at 3bar will be perfect for 400bhp. You'll need a high-flow fuel rail, too, and a stronger fuel pump. If you want that power at the wheels, however, you'll want to bump the fuel pressure up to 4bar. Low-impedance injectors will make your tuning easier because of the quicker response time.

      I'm looking for fuel pump requirements as far as how much I need a fuel pump to flow to meet my needs. And yes a custom fuel rail will be on the car as well

      Either a Bosch Motorsports pump or Walbro 255lph will take care of your 400whp nicely. If you "only" want 400bhp you'll have that much more reserve flow capacity. Just make sure that you've got the pump hardwired to get full 13.x voltage and you'll be good to go. [IMG]http://**********************/smile/emthup.gif[/IMG]

      How much are you guys asking for the Walpro 255 unit? I'm checkin out your Fire and Fuel unit but have a somewhat difficult question....Do you guys recommend running stand alone for a beginner? I have read some technical books on fuel management and have a local that tuned his b16 on stand alone for a reference but I'm just not sure. I don't wanna fork over the dough for a chip since that will run nearly half the cost of F&F and since boost is addictive.... yea. How user friendly would this be for a guy looking to boost his 2.0 to a max of 12-ish PSI? Depending on how cheap i can find a spare block to build right, I dont believe I would push it any higher.

      Most any standalone engine management takes a bit of experience to install. If you can read a wiring diagram, can do light electrical fabrication (soldering and such), know sensor layout, and fundamental engine mechanics, then you'll have no problem at all. In other words, you don't need to be an engineer, but you do must have a comprehensive understanding of what's going on under the hood. It isn't a rank amateur's job. FnF also requires PC skills since it is currently based on MegaSquirt.

      The amount boost that you're looking to run isn't very relevant to the install. However, programming any standlalone on a forced induction engine requires knowledge and skill. I wouldn't jump into this if you're clueless. Pay for a professional to do it and you'll get superior results that exceed the performance that chips can offer.
      Remember that we also offer 034EFI which is the better deal if you need hand holding. FnF's value is strongest for those who can work more independently.

      Well I don't consider myself an amateur but I'm no pro either. I am going FI since my VR swap last summer ended up with a cracked block so this is option 2 since I don't wanna look all over the area for a decent parts car again. I'm pretty technically and PC inclined. The current book on diagnostics I'm reading is How to Tune and Modify Engine Management Systems by Motorbooks Workshop by Jeff Hartman. I'm not sure if you would be familiar but its pretty easy to pickup and comprehend. You're 034EFI is just way out of my price range for such a mild turbo setup, I just want to be able to alter boost in case I end up changing compression ratios, upping the injector size, etc. The reason I mentioned my boost goal was to maybe highlight how in depth the tuning would require yet when I think back it was a horrible question since I would basically be starting with a blank system and going from there instead of starting from OEM specs and then going. Thanks though. I don't plan on rushing into anything crazy without finishing the current book with complete understanding of what it is saying. Thanks a lot though [IMG]http://**********************/smile/emthup.gif[/IMG] Now I just need to figure out a decent, reliable clutch for that kind of power.
      From the other comments you have posted, I assume that the F&F system would work well for what I am trying to do (MK3 ABA mid to low level boosted street setup)?

      If your F&F system is based off of Megasquirt, whats the real difference between your product and the MS v2.2 or v3?
