just wanted to know if anyone herr on the forum has installed an aftermarket fuel rail with aftermarket fuel pressure regulator and heard a quite noticable pulse coming from the rear of the rail, i heard it the first time last night after installing my hks fuel rail and want to know if its normal and if anyone else has had the same things happen

but my 720cc injectors didnt make much or any noise in the standard rail, but after installing the hls one it makes quite a loud pulse, not sure if its casue of the anodised alluminium rail.

Yeah its also amplified because of the larger internal diameter of the rail too.

no idea mate, i bought the car with no idea what engine work it had done, but ive been killing it for the last 18months, and seems to be holding, it has really loud piston slap when its cold but after i warms up it goes away, i was told thats a tell tale sign it has forgies, but im not sure, so ill race it till it dies, then rebuild from scratch.

its the only way to do it, why rebuild now when it still has potential to run low 10s without touching anything.

exactly...why spend money when you don't have to...Its like these idiots that upgrade their gtr intercooler before their ecu??? go figure!

      It's so pretty, but I cry at the price (this setup was about $7,500 USD)

      Yep, I installed it, the sensors, wired everything up so things like the factory blinkers work etc. Fortunately it's not a hard job, just time consuming sorting the wiring out.  If you think this dash is nice, you should check out the actually sexy dashes lol. There would be a fair few people out there that think the IC7 is ugly.  The new and sexy Haltech dash -  https://www.haltech.com/news-events/uc-10dash/ Here is a, I hate having money option from Motec -  https://precisionracing.com.au/product/motec-c1212-display/

      @Murray_Calavera ohhh.myyyy.gawwwwd 😍 that dash is so much cleaner.  yeah I’m someone who loves older cars, but hate using old tech. A digital dash would always be the way forward. Did you install that yourself?  Thanks for the explanation on oil pressure. I’ll just take it as reference.    Also, your engine light is on 😅😅😅

      @DraftySquash Yeah... maybe think of those gauges as a super rough estimation of oil pressure and engine temperature.  If you want to see your actual engine temp and oil pressure, you're going to need an aftermarket solution. I'll post a photo of my dash, this is a much neater solution in this day and age. I can't think of any reason why someone would start adding individual gauges.  So grab your dash, then add sensors for all the extra things you want to see.  As for what to expect from oil pressure, super quick run down = cold oil, higher pressure. hot oil, lower pressure. Low revs, lower pressure. higher revs, higher pressure. The values will change based on the viscosity of oil used, the actual temperature of the oil, the type of oil pump used, then more nuanced stuff like clearances in the engine.

      Should run up to about 6 or so at high revs. But the stock oil pressure gauge is a piece of shit and can't be trusted, so make few to no decisions based on what you see it do.
