NorthWet Posted June 11, 2005 Share Posted June 11, 2005 As least one of the members has been looking for quite awhile for the specs (flow maps) and hasn't found them. Don't be surprised if you don't find any. Link to comment Share on other sites More sharing options...
Myxalplyx Posted June 11, 2005 Share Posted June 11, 2005 Not sure if this is the same turbo in this chart but does this help? Link to comment Share on other sites More sharing options...
WJM Posted June 11, 2005 Share Posted June 11, 2005 vf2 should be the same as VF7. all EA82T's got VF7s. Link to comment Share on other sites More sharing options...
TurboSPFI Posted June 11, 2005 Author Share Posted June 11, 2005 Not sure if this is the same turbo in this chart but does this help? If i can remember right, the RHF's are different than the RHB. RHF = new school RHB = old school what do you want to know? can you be more specific? Eh, such things as: stock boost setting max avail. boost setting EGT tolerances basically anything that can distinguish specs between a VF2, VF7, VF11, VF39, etc etc etc Link to comment Share on other sites More sharing options...
TurboSPFI Posted June 11, 2005 Author Share Posted June 11, 2005 vf2 should be the same as VF7. all EA82T's got VF7s. if it was, it would say VF7 then instead of the VF2 stamped on the thing :-\ (wouldnt it??) Link to comment Share on other sites More sharing options...
NorthWet Posted June 11, 2005 Share Posted June 11, 2005 if it was, it would say VF7 then instead of the VF2 stamped on the thing :-\ (wouldnt it??) Not trying to put words in Will's mouth, but what I believe he meant was that funtionally they are equivalent, that the number difference reflects more of an application difference... as in, slightly different mount flange.

Vanislru Posted June 11, 2005 Share Posted June 11, 2005 Eh, such things as: stock boost setting max avail. boost setting EGT tolerances 7-9PSI max depends on the boost controller you usebut over 11psi will start to be inefficient unless you do some porting on the exhaust snailshell. EGT- skies the limit as hot as you can get it. Link to comment Share on other sites More sharing options...
NorthWet Posted June 12, 2005 Share Posted June 12, 2005 ... EGT- skies the limit as hot as you can get it. There will be a practical limit due to turbine material, and it would need to be derated with increased speed caused by trying to up the airflow/pressure. I would get a baseline from a properly running application, and be very careful about significantly exceeding this. Link to comment Share on other sites More sharing options...

All_talk Posted June 14, 2005 Share Posted June 14, 2005 OK, here's the scoop, I've been looking for flow/compressor maps for the RHB5 for years... They don’t exist, Warner-Ishi (IHI) never released any for the VF series. The only one I’ve found is from the book “Turbochargers” by Hugh Maclnnes, it show a very sparse map (no efficiency lines) for the 311A and 393B trims… whatever those are? If anybody ever finds others please let me know. Some info and flow mapping of the TD04-13G (WRX) and RHB5 in this thread: http://www.ultimatesubaru.org/forum/showthread.php?t=22146&page=1&pp=10&highlight=flow+map+tdo4%2A Gary Link to comment Share on other sites More sharing options...
All_talk Posted June 14, 2005 Share Posted June 14, 2005 FWIW, I have a spare turbo reportedly off a EA82T that looks just like the one on my RX and Turbo coupe (both EA82Ts) that is stamped VF2. Gary Link to comment Share on other sites More sharing options...
Quidam Posted June 27, 2011 Share Posted June 27, 2011 (edited) FWIW, I have a spare turbo reportedly off a EA82T that looks just like the one on my RX and Turbo coupe (both EA82Ts) that is stamped VF2. Gary I looked around and one of the places I ended up was here. So on with the reserection:) That's Turbo Spec. VF2 8407. I made note of the 2 in the PartsNo. And that unusual for me Serial No. What I've learned is there was a VF1. 1 thru 8, no 9 that I've found, then 10, 11, and so on. This one is a like new survivor I guess by the looks of it. I got it off an '87 Turbo Traction Wagon. I suspect it is from 1985 tho. I have VF4 as the most common. One of them is barely magnectic with a super magnet. Doug This list in some variation is all over the world.
