spect2k Posted November 3, 2007 Share Posted November 3, 2007 Hey, Obviously there is no boost gauge in the Spec B. I just picked up an 08 and am wondering what the stock PSI is on the turbo? Maybe it varies by the 3 modes? Thanks! Link to comment Share on other sites More sharing options...

mickeyd2005 Posted November 3, 2007 Share Posted November 3, 2007 The stock 07+ cars run higher boost than the 05-06. Here's a datalog comparison. Keep in mind that the 07 datalog was started at a higher rpm. This affects boost below 3000 rpm. However, boost above 3000 rpm is a valid comparison. The 07 datalog was done using a VAG-COM cable and enginuity logger. http://i141.photobucket.com/albums/r69/mickeyd2005/2005lgtvs2007lgtmrp.jpg Link to comment Share on other sites More sharing options...

rudy Posted November 15, 2007 Share Posted November 15, 2007 In the 07/08 AP thread, Christian seems to suggest that their logs show ~13.2psi peak, consistent with prior model years. Link to comment Share on other sites More sharing options...

rice_rocket Posted November 15, 2007 Share Posted November 15, 2007 So.. what is the max boost the engines can take? (Newbie here) 05/06 versus 07/08? Link to comment Share on other sites More sharing options...
chenc544 Posted November 15, 2007 Share Posted November 15, 2007 So.. what is the max boost the engines can take? (Newbie here) 05/06 versus 07/08? Should be the same, there is no changes to the short block AFAIK. Link to comment Share on other sites More sharing options...

Darkness of Death Posted November 16, 2007 Share Posted November 16, 2007 how do we figure this boost level? i've installed a blitz dual turbo timer with boost gauge. and i've push out 1.12hkpa (16.25 Psi )on a bone stock car with just a perrin panel filter. is this wrong then? or is that boost level to be noted at a certain rpm?

jvcjbl Posted November 16, 2007 Share Posted November 16, 2007 According to Corporate guys at work the car is running 13.5PSI... but then again this is only what I am told from corporate. -Jason Avondale Subaru Link to comment Share on other sites More sharing options...
mickeyd2005 Posted November 16, 2007 Share Posted November 16, 2007 Just to be clear... the chart posted in post #6 is not a Spec B. Carter doesn't have a Spec B either. Link to comment Share on other sites More sharing options...
mickeyd2005 Posted November 16, 2007 Share Posted November 16, 2007 In late 2005, SOA developed a new rom to correct stutter. It put a time delay in the WGDC to cap it at 30.2% for a set time. All reflashed 2005 cars plus all 2006 cars have this time delay. These cars will not be able to hit peak boost in 3rd gear. In 4th gear, they are more likely to hit peak boost. I have reviewed the 2006 Spec B rom. It is 100% identical to the 2006 5MT rom. Same calibration id. The numeric values in the boost control are the same as the 2005 models and their datalogs show the same boost values. Anyone who autocrosses in STU class should not buy a 2006 car. http://i141.photobucket.com/albums/r69/mickeyd2005/hyteck9specb.jpg Link to comment Share on other sites More sharing options...

praedet Posted November 16, 2007 Share Posted November 16, 2007 The amazing part w/ that graph, is the Spec-B is SUPPOSEDLEY hitting that 15 at 2k RPMS. Show me a VF40 that does that in 3rd Moreover, it hits it instantly, with no transient Vimy, you crack me up Edited after Mickey:Man, Vimy actually had me going You are right mickey, that is AFR. Boost is not shown anywhere on the plot Link to comment Share on other sites More sharing options...
