selbekk 0 Posted December 16, 2005 Okay, I was just doing a couple of runs down my local c-roads, and I got a boost reading of close to 1.5 (probably 1.45 or so) bar. At about 6900rpm. Is is usually this high? Gotta admit I got a couple of underbonnet tweaks (65mm pulley, chip, cotton air filter), but nothing major. I recon'd I would get about 0.8-1.2 bar with this setup. Is my gauge fcuk'd or am I doing good with my g60? I made my personal best, 160 km/h, today, racing a couple of friends in an abandoned tunnel. Scary as fcuk, on snow tires and all, but it was a real thrill. Quote Share this post Link to post Share on other sites
Guest Posted December 17, 2005 1.5 bar is very good mate. I'm pushing 1.25 in the inlet. Did you take the reading from the t/b or inlet? Quote Share this post Link to post Share on other sites
catch_twotwo 0 Posted December 17, 2005 I thought the ISV vented the excess boost at 1.4 bar ? or are you using a re-route ? Quote Share this post Link to post Share on other sites
Timo. 0 Posted December 17, 2005 1.5 bar is about 21psi !! That's pretty bloomin' high T. Quote Share this post Link to post Share on other sites
Guest Posted December 17, 2005 catch_twotwo[/] bleeds at 1/1.2 I'm told. Quote Share this post Link to post Share on other sites
Guest Posted December 17, 2005 If reading from the tb it will appear higher. You wanna know whats going into the inlet. Quote Share this post Link to post Share on other sites
selbekk 0 Posted December 17, 2005 I have no idea where it reads from, actually. I just have a nice lil' gauge sitting in my dash, telling me the info I need :) I don't have a re-route kit. Quote Share this post Link to post Share on other sites

gibber 0 Posted December 18, 2005 Thing is that boost pressure is just backed up flow that cant get into the cylinders. Now get that head and manifolds ported out and get that psi right down and then your talking! Thats where my next line of attack is. Quote Share this post Link to post Share on other sites
lindy33 0 Posted December 18, 2005 i was running a 63mm pully on ported and polished charger with isv re-router and was running 17psi then put a piper 268 cam and only getting 12psi, this confused me and when i questioned my supplier its cos the head is breatheing easier so no boost backing up to give high readings, now im 190 bhp which is not bad i recon .
