stelios51 Posted June 9, 2012 Share Posted June 9, 2012 I'm getting a vf34 turbo kit with external waste gate with a 14psi spring in it but I'd be wanting to run at least 1.5 bar but is it better to use just a stronger spring or use an apexi avcr boost controller to adjust it ? Which is a better idea ? Thanks Quote Link to post Share on other sites
ep91steve Posted June 9, 2012 Share Posted June 9, 2012 Use the boost controller mate Quote Link to post Share on other sites
stelios51 Posted June 10, 2012 Author Share Posted June 10, 2012 Will it hold the boost better Steve ? Quote Link to post Share on other sites
Burny Posted June 10, 2012 Share Posted June 10, 2012 U want a spring pretty close to the boost u want to run mate, im going to run a 1 bar spring but run 1.4 bar through my AVCR, apparently its harder to control with the boost controller if your running a spring way off your highest boost setting, i wanted a lower pressured spring so i could run low boost in first and second but now il have to run atleast 1 bar, i was told this by Mike at TD :-) Quote Link to post Share on other sites
stelios51 Posted June 10, 2012 Author Share Posted June 10, 2012 Alright so if I had a spring rated to 1.5 say then will I still use the boost controller ? Or just do without ? Quote Link to post Share on other sites
Burny Posted June 11, 2012 Share Posted June 11, 2012 Well i suppose it would be cheaper to just use a spring if u always wanted to run 1.5 bar mate, boost controllers are good if u want different settings etc, im not sure though if they also help with boost creep so maybe it will help you over boosting past 1.5 bar, im not 100% on that though.....

AdamB Posted June 11, 2012 Share Posted June 11, 2012 You can use a boost controller to help spooling a turbo by the gain feature. I would stick a 1 bar spring in as you can always switch a boost controller off and back down to 1 bar Quote Link to post Share on other sites
stelios51 Posted June 12, 2012 Author Share Posted June 12, 2012 Tbh I'm not bothered by a hi and low kinda idea I'd just Hav 1.5 bar permanent I don't like goin slow , it's my car for fun n fast not borin haha , so if I had a1.5 bar spring with no boost controller u think it may creep ?

Burny Posted June 12, 2012 Share Posted June 12, 2012 Im not 100% mate as my car is also being built so ive been asking questions like yourself, my civic turbo is just running a wastegate spring though and it does feel like im getting boost creep, i dont have a boost gauge in her lol Quote Link to post Share on other sites
stelios51 Posted June 12, 2012 Author Share Posted June 12, 2012 Mmmmmm think u need to invest in one haha , and well it's either use my avcr or sell it to fund more goodies Quote Link to post Share on other sites
Burny Posted June 13, 2012 Share Posted June 13, 2012 Id keep the avcr mate there good bits of kit :-) and i only bought it as a run around until my glanza is forged so not spending no money on her lol Quote Link to post Share on other sites
pick1 Posted June 13, 2012 Share Posted June 13, 2012 If your funds will allow it mate run the avcr and your spring so your chances of boost creep is as low as possible Quote Link to post Share on other sites
stelios51 Posted June 14, 2012 Author Share Posted June 14, 2012 Right well think I'll keep it then I've the guy mucks about at all Quote Link to post Share on other sites
Jamie1st Posted June 15, 2012 Share Posted June 15, 2012 I run 2 springs in my external W/G, that are between 1bar and 1.1bar, then use my Apexi AVCR to take it to 1.4 Quote Link to post Share on other sites
