JCviggen Posted December 14, 2008 Report Share Posted December 14, 2008 So once a month or so I click past Swedespeed and never post a thing but the sheer idiocy of this just made me post So the topic is about the highly advanced procedure of tightening the WG actuator arm 1 or 2 turns, with great results for all involved.JRL also put a knee slapper on the first page about his one-off super agressive tune that makes his car hard to drive when its cold Figured I wouldn't get into that.

irf Posted December 14, 2008 Report Share Posted December 14, 2008 there's no arguing with some people on forums JC, it's why i'm now avoiding going to certain forums myself(not swedespeed, i'm not even a member there). Link to comment Share on other sites More sharing options...
flyfishing3 Posted December 14, 2008 Report Share Posted December 14, 2008 whats funny/ shame jim is actually a pretty nice guy in person.i've been over his house, hung with him at many meets etc.he's a different bird for sure, but he's forgot more than most of us will ever know. he gets pissy when the same discussions come up for the elleventybillioth time to him.just ignore him unless your looking for fun and then get him worked up with grammar and punctuation. he gives me crap becuase i don't CAP anything + my grill hahaha.

JCviggen Posted December 14, 2008 Author Report Share Posted December 14, 2008 He must have forgotten a lot of technical stuff I don't see any excuse for not having a clue how something as simple as a wastegate works. First rule when you're blasting someone, make sure you know what you're talking about :) Link to comment Share on other sites More sharing options...
Zulu Posted December 14, 2008 Report Share Posted December 14, 2008 Never paid any attention to the whole JRL vs VS thing...but that is stupid as hell. I hate people perpetrating bad information. Link to comment Share on other sites More sharing options...
RZT5 Posted December 15, 2008 Report Share Posted December 15, 2008 Hate to say it but JRL may be right on this one... Depending on the strength of the spring in the actuator, the exhaust gas pressure may be enough to push the wastegate open a little and bleed some pressure around the turbine causing it to spool slower than it should with a properly chosen wastegate actuator spring. By tightening the WG actuator arm you are in essence increases the value x in the equation F=kx thereby increasing the force exerted by the spring which in turn holds the wastegate closed with more force causing the turbo to spool faster Link to comment Share on other sites More sharing options...
RZT5 Posted December 15, 2008 Report Share Posted December 15, 2008 i just read JRL's post again, hes right but for the wrong reason "it allows the wastegate to open almost immediately" he is supposed to know his stuff, and here he is saying that an open wastegate builds boost?

khax Posted December 15, 2008 Report Share Posted December 15, 2008 yeah seriously, everyone knows that's not how a wastegate works.:lol: Link to comment Share on other sites More sharing options...

This is definately an issue at higher rpm but most certainly not at 0 , 1000, 1500, etc rpm.Noticing a vast improvement "even at 1100rpm going from -18 hg to 0 pressure much faster" is complete BS.

javadoc Posted December 15, 2008 Report Share Posted December 15, 2008 JRL also put a knee slapper on the first page about his one-off super agressive tune that makes his car hard to drive when its cold I always find that humorous. His 'super-aggressive tune' is less so than what I run with, and I think the car's "alot" of fun in the cold.Isn't it "Eleventeenbillion," though? ;) Link to comment Share on other sites More sharing options...
NEU Posted December 15, 2008 Report Share Posted December 15, 2008 whats funny/ shame jim is actually a pretty nice guy in person.i've been over his house, hung with him at many meets etc.he's a different bird for sure, but he's forgot more than most of us will ever know. he gets pissy when the same discussions come up for the elleventybillioth time to him.just ignore him unless your looking for fun and then get him worked up with grammar and punctuation. he gives me crap becuase i don't CAP anything + my grill hahaha.I agree, he has help and saved me time and money with my 5 speed auto. He's the guru of '00R info, he really knows his stuff, but he is a prick at times... I've met him at GTGs and talked to him for a long time and he is super nice puffing on his cigar... Its hard for me with grammar and spelling rules cause I've got a learning disability and try hard not to make mistakes and but he rails on like he's my 1st grade teacher.... :( Link to comment Share on other sites More sharing options...

Karlson Posted December 15, 2008 Report Share Posted December 15, 2008 Noticing a vast improvement "even at 1100rpm going from -18 hg to 0 pressure much faster" is complete BS.+100. It is not even that difficult to check. Good boost gauge will show him the "improvements". If he will find incrase from 20 to 0hg I will buy him a beer. Increase in boost-yes, in vac.. nope Link to comment Share on other sites More sharing options...

PaperToast Posted December 16, 2008 Report Share Posted December 16, 2008 he does know most of his stuff, but tactless is prolly a mild way of putting his way of interacting with people on the forums.just browse some posts on Volvo XC Forums and you can see some poor folks trying to get input on stuff and getting flamed by him.we all ask dumb questions .sometimes a dumb answer is needed but not all the time.just my 1 cent.
