I may be imagining but i took my heatshield off again to test my actuator and snapped a bolt taking the heatshield off,....so i left the shield of went for a drive and it seems to be boosting less? :glare:. 10 psi instead of 12-13

Maybe its all a big coincidence(<spelling) ;) but ive heard people put washers or cut heatshield ?is that true?

Is it safe to run without shield for a little bit?but wires and looms get quiet hot :nyaanyaa:

Im now running a unrestricted hose straight to actuator!, bleed valve i will throw out i think lol

I cant imagine the actuator hitting it because the actuator diaphram only moves 15 mm or so.

Im also happy with direct actuator hookup because it boost more gradual and fixed spiking alot

anyone had simular experiences?

at the end of the day its probably not going to be that, but i would put it back on, the heat shields were put in place for a reason, im a firm believer in heat soak and the ways it disrupts performance, i've vhanged to a hi mount gt35r setup but my ive heat wrapped my whole exhaust manifold, dump pipe, intake pipe that goes over engine and intake pipe off turbo, and got a turbo bag for the ex housing on turbo, minimising heat can have good effects on the cars performance... my 2 cents anyway

when i bought my line, it came without the heatshield. it works perfectly. even after 6 hours of intense driving with mates, it still works perfectly.

it wont make much difference

i took to mine with an angle grinder, not the actual shield but the bracket its bolted to, to make it fit with the new dump pipe. the difference in temp in the engine bay was noticable for me when it was off so i wacked it back on.

      Ha ha ha, mine loves to spend, all on the dogs (they're our kids, and her spending would likely rival that of some people raising children!) the only benefit is, her spending is tax deductible as she runs a business in the dog industry 😛 The above all means she can spend race car budget quicker than I can. 😛 That and a lot of the things I want are very expensive, and I can be a bit "you want how much for that?!" And at other times overly impulsive. Or I start the w days of research, get to day 1.5 and get really annoyed that no one will advertise actual specifics and it's just marketting BS and I go "well, now I don't want anything to do with that now!" Also I hate paying lots of money for something I can make from $50 in materials. Then I get the shits halfway through making things and wonder why others who just buy parts have more fun... 😛

      Their 240Z with the RB26 would be a real nice thing to have in a garage to come out for an occasional weekend cruise It's such a cool thing in so many ways Sadly, we have a blue 240Z shell that I walk past every day, just sitting outside a shed at work, it has been slowly disintegrating and falling apart into the ground for the last few years, the owner cannot be found, and I am unable to "claim it" I've been told by work and the RMS, the rust in the body is excessive though, and it has had most of the salvageable stuff, like panels, trim and switch gear stripped off it over the last year or two, work keeps threatening to put it in one of our metal scrap bins, I wish they did though, as it makes Mark sad walking past it

      Good tips, I like it! 😂😂 My wife is a LOT more frugal than me so it's only me we need to worry about! A splurge to her is buying 2 pairs of socks in one visit at Kmart!

      Haha, the appropriate response to the question "Is this new?" is "I've had this for a while.". With the unspoken small print that a while may be the time since this morning or five years ago   And to be fair I learned that from the best, i.e. my wife. Because it goes both ways.

      Yeah kids certainly add a whole another dimension to your life.  Life ceases to be about you and more about them for a while!  And I wouldn't have it any other way.  I love watching them play sport and make new friends along the way. Wow, sounds like your mate is a good guy to know!!!  He's got some serious toys in the toy box!  Yes it would be lovely to be able to do stuff to your car without getting all tied up in boring shit like how to pay for it!!  I would describe my spending style as "aggressively spontaneous and logical but regrettable purchasing"....  That will hopefully make no sense at all which would be appropriate given that is how I buy stuff.  I'll decide at the drop of a hat that I'm buying something expensive, research the living shit out of it for 2 days straight then go out and buy it.  Then I'll have instant buyers remorse for 2 days which generally passes by the time it turns up on the front step!  If I'm feeling ballsy sometimes I'll tell my wife.  Other times it just makes its way silently passed the house and out the back to the shed, never to be spoken of again...
