Installing Fmic And Ebc

Hey guys,

My HDi Gt Spec intercooler and EBC arrived yesterday and I plan to have them installed this weekend. I just wanted to know, considering the car is completely stock, what I could expect to see performance wise (whether it be a positive or a negative outcome). Like will I have turbo lag or any other problems? I just want a heads up so I don't freak out lol.

I know I should have installed an exhaust first but I got a good deal on this stuff so I took it. Next step would be a full 3" system. Oh and I was thinking of setting my boost controller at 8psi for low and 9psi for high (too much??).

Any information or advice would be awesome.

Cheers,

Chris

front mount may give you slightly more lag because of the larger air volume to fill, but it will change the induction sound more than anything else. 8-9psi should be fine but there's not much point going higher until you sort the exhaust out, and once you do I'd run no more than 10psi considering where you live. Heat is the enemy of stock turbos but 10psi will be safe.

Ok so the fact that the intercooler is dumping more cold air into the pistons will mean that too much boost will be produced for the stock exhaust to handle?? And how would the induction noise change?

Maybe I should just hold off until I can afford an exhaust :)

it's not a case of too much boost for the exhaust to handle, the more you try and force air through (boost) the more your exhaust backpressure goes up to oppose it. fit a nice free flowing exhaust and the backpressure drops away meaning at the same level of force (boost) you push a lot more air through the engine. think of an engine like an air pump, the more air (and fuel) you get through it the more power you make. boost is just a measure of restriction, you're applying 10psi of pressure to try and get air to move through the engine.

So will this build up of backpressure stress the engine? It really does sound like installing a fmic prior to an exhaust isn't a good idea. So a nice 3" exhaust from the turbo back should allow better flow (was thinking a kakimoto cat back with a bellmouth front/dump) to balance the amount of boost produced by the intercooler?

      Are you an oil nerd?

      I think the concept is highlighting the various scenarios where thicker oil helps, and thicker oil potentially doesn't help and only generates heat and costs power, in turn for safety which isn't actually any safer (unless you're going real hot). If anything this does highlight why throwing Castrol 10w-60 for your track days is always a solid, safe bet.

      Jason should have shown a real viscosity vs temp chart. All the grades have very little viscosity difference at full operating temperature.

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      Yep, if you are applying filler it sounds like there is something wrong with the body lol. Safe to assume there is going to be a lot of sanding going on if your still applying fillers.  Picture a perfect bare metal panel, smooth as glass. You lay down your primer, it's perfect. (why are you going to sand it?) You lay down the colour and clear, it's perfect. No sanding at all took place and you've got a perfectly finished panel.  You won't be chasing your tail, sounds like you were prepping to start laying filler. If your happy with the body after the sanding, there is some bare metal exposed and some areas with primer, no issues at all, start laying the filler. You are safe to lay filler on bare metal or primer (of course check your technical data sheet as usual for what your filler is happy to adhere to).  This isn't a 100% correct statement. There is primer that is happy to adhere to smooth bare metal. There are fillers that are happy to adhere to smooth bare metal. Just make sure you're using the right materials for the job.  Typically if you are using filler, you would go primer, colour and clear. I've never seen any instances before where someone has laid colour over body filler (maybe this happens, but I haven't seen it before). So your plan sounds pretty normal to me.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I don't think there's any way someone is push starting this car.. I honestly can barely move it, and moving it and steering it is just flat out not possible. I'm sure it is, but needs a bigger man than me. I have a refurbished starter now. The starter man was quite clear and consise showing me how nothing inside a starter really should contribute to slow cranking, and turned out that for the most part... my starter was entirely fine. Still, some of the wear items were replaced and luckily it didn't show any signs of getting too hot, being unfit for use, etc. Which is 'good'. I also noticed the starter definitely sounded different, which is a bit odd considering nothing should have really changed there.... Removed and refit, and we'll pretend one of the manifold bolts didn't fully tighten up and is only "pretty" tight. GM only wants 18ft/lb anyway. I also found a way to properly get my analog wideband reading very slightly leaner than the serial wideband. There's Greg related reasons for this. The serial output is the absolute source of truth, but it is a total asshole to actually stay connected and needs a laptop. The analog input does not, and works with standalone datalogging. Previously the analog input read slightly richer, but if I am aiming at 12.7 I do not want one of the widebands to be saying 12.7 when the source of truth is 13.0. Now the source of truth will be 12.65 and the Analog Wideband will read 12.7. So when I tune to 12.7 it'll be ever so slightly safer. While messing with all of this and idling extensively I can confirm my car seems to restart better while hot now. I did add an old Skyline battery cable between the head and the body though, though now I really realise I should have chosen the frame. Maybe that's a future job. The internet would have you believe that this is caused by bad grounds. In finding out where my grounds actually were I found out the engine bay battery post actually goes to the engine, as well as a seperate one (from the post) to the body of the car. So now there's a third one making the Grounding Triangle which is now a thing. I also from extensive idling have this graph. Temperature (°C) Voltage (V) 85 1.59 80 1.74 75 1.94 70 2.1 65 2.33 60 2.56 55 2.78 50 2.98 45 3.23 40 3.51 35 3.75 30 4.00   Plotted it looks like this. Which is actually... pretty linear? I have not actually put the formula into HPTuners. I will have to re-engage brain and/or re-engage the people who wanted more data to magically do it for me. Tune should be good for the 30th!
