  1. Been working through that over the past 4 or 5 days. Good read when I actually had time to read, lol.
  2. Gotcha, no I am talking about for big engine high hp builds. It seems ok other than that provided people realize these are crank hp.
  3. What VE numbers did you change to get a 8.8 liter to 480 chp at 7 psi? VE of 25, lol. I did change them, I also adjusted the rpms to start at 1000 rpm to max of 6000. As for the BCFC I am not sure exactly what to put them to.
  4. Not sure how accurate it might be when you start getting up there in the hp range though. I played with it a bit and it said that at 7 psi my 535 CI big block Ford motor will be making 1000 hp. Not sure how accurate that might be. Similar with the 03 Cobra motor we ran the numbers on. I would call that particular program more of an "Ideal" calculation, not necessarily what might be seen in the real world. Take for instance the difference in the Subaru exhaust system vs an Evo. There is an obvious difference in spool, exhaust runner length, heat loss, etc. But matchbot does not take this sort of thing into account. It goes by an ideal situation. Either way, great program for getting you into the ball park.
  5. Here is the one he saw Just thought I would snap a couple photos of the new EFR turbos we got in at the shop We got some of the very first ones to come down the production line. This particular one is the smaller frame EFR6758. It is 30R or a little smaller in size. Some cool things to note: you can see the BOV port on the compressor intake if you look close. It is angled slightly where the air is directed right back at the wheel. On the turbine side you can also see the internal wastegate. It really is a pretty cool design. It is the first time I have been impressed with an internal wastegate. Sorry the phone pics really don't do it justice, but it was all I had on me. http://i656.photobucket.com/albums/uu290/sargmike/IMG00061-20110103-1332.jpg http://i656.photobucket.com/albums/uu290/sargmike/IMG00058-20110103-1330.jpg http://i656.photobucket.com/albums/uu290/sargmike/IMG00056-20110103-1329.jpg http://i656.photobucket.com/albums/uu290/sargmike/IMG00054-20110103-1328.jpg
  6. I am not sure that the 7670 is going to be for "big" street use. I think it is just going to be more of a spool happy little turbo that is 30Rish in size. Personally on the 2.5 block that is the absolute smallest I would go. With a 35R sized Borg we were able to make 12 psi off the line, 28 psi by 4700 in 3rd (6 speed) and 28 psi by 4200 in 4th. That to me is just about right. I guess it is all about what you are trying to accomplish. It's probably not good for autocross, but then again, I don't spend too much time racing around parking lots.
  7. There is something to be said about low timing high boost. The "JDM style" of tuning with high timing and lower boost can be harsh on the motor.
  8. I am sorry, but you guys are wrong. The factory block does in fact have sleeves. We have seen where the factory sleeve has cracked and peeled away from the block. It is my understanding (and I could be in correct on the process) that the factory block is poured and cast around the sleeves which have ribs built into them to help hold them in place. They are some what thin and may not be visible in the above picture, but they are there.
  9. There is a sleeve in there in stock form. I forget who it was that made them, but there are sleeves. I have seen them and seen them with cracks. They are most definitely not the same as the rest of the block. They may be a bit thin, but they are sleeves none the less.
  10. We have run more than 24 psi on a variety of blocks without sleeves. Don't expect to run 25 degrees of timing while doing it, but I would not say there is some artificial 24 psi limit on stock sleeves.
  11. So any pics of the twinscroll internal gate housings or do we have to wait till Nov 2?
  12. Seems most are more excited about the factory location turbos than the rotated kits. We do have a BIG hp LGT wagon in the works at our shop though with a rotated kit. They are out there, but much more uncommon for some reason.
  13. I do not think it would work with the factory controller. To be honest I am not sure. But it is easy enough to hook it up to MAF, TPS or a hobbs switch. Here is a link to them. http://www.fuelab.com/index.php?option=com_virtuemart&page=shop.browse&category_id=1&Itemid=3 From instructions: Pulse-Width Modulation or other means of reducing input power voltage may result in erratic or non-operational condition Something else cool about these: Fuel Pump may be mounted inside a fuel tank or cell We actually are installing one of these in a Legacy GT as an in tank pump in the next week or so.
  14. Actually the Fuel Lab pumps have a built in controller so that you don't have to run it 100% all the time. It does 66% at low mode and 100% at high mode that is switchable through any 0-5v source.
