My mate had -9's stock 34 GTR bottom end, cams, head studs and made 360ish kw at 26psi if I recall

Do head studs and keep boosting till there's nothing left

Don't think you will go over 26psi with such small rear housings

I've seen another 2 that were reported as making 370s one on 98 and the other on e85

Given what was said about the position on the comp map etc, I can't imagine it would make more than 350 or so, but then again you made that on -7s... Tuner did say his dyno tends to read a bit lower than the other locals.

Cams help top end a fair bit.

Seems head studs are a wise investment though. Saves replacing the whole gasket which is a flamin mongrel of a job in a CA, so would be heaps worse in a 26.

If you made 348 on -7s, is it not reasonable to think -9's could make 10-30 or so kw more?

Genuine question, not baiting etc.

I realise different dynos, different days etc.

Stock manifolds, exhaust is Midori dumps then 2x3in into 3.5in the rest of the way, can't remember where the cam gears are set, haltech plug in and full boost is before 4000rpm

Similar to me then. N1 manifolds, HPI 3" dumps into 3.5" front pipe and 3.5" the rest of the way. Same ECU. Full boost seemed laggier to me though. I will do some proper plotting to confirm though.

Yes I realise -9s are bigger/laigger and also that larger ports in the N1s will not assist response.

The extra power is just a nicety and something to keep me happy. The pods is the same, make it noiser and more dramatic/fun to drive. Same as removing the mid muffler, more noise, more fun.

I can get a video when it dries out enough for me to get it out of the shed and drive it.

How power feels from one person to the next is relative, 330rwkw in a 1500+kg car isn't that much. Some of the "drama" is also lost purely because the 34 hooks up so well. I could put cheese cutter tyres on it and do mad skids everywhere and it would be more exciting to drive lol

Haha, I will be for the next tune if I do this.

Even still, I was surprised to find how little, as in almost zero, front drive was being engaged through the hill run. More an indication of how much harder I could have pushed grip wise. It only has ATR Sports on it, but they're 275 so even if they're a cheap tyre, there's plenty of it. Probably on par with a half decent 255 which is all my old one had on it.

Mine start pushing coolant on 20psi e85 350kw or so.

Just do studs and gasket while engines out save doing it twice like me.

why would he be taking the engine out?

Didn't I say head studs a page ago?

we all have

I don't think you have pushed the car hard enough yet to enjoy it. I know in my 32 with 265 z221 hankooks its grips like mad through the hills but if you push hard enough it will still step out. That was with 332kw with -5 dinosaurs.

Owned and driven a few fast cars but the GTR keeps me happy. Don't get me wrong evo's are great but it's not the same driving one.

    • The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.
    • Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?
    • You can probably scrub the rust with a toothbrush or something. After you get the rust off flush well with water to neutralize and you will probably want to also use a fuel tank sealer to keep it from rusting again.
    • The sodium citrate solution is designed to buffer the citric acid to keep it from attacking metal quite so much, the guy that came up with that recipe did a ton of testing on how much metal loss occurs over time and it's nothing crazy unless you forget about it for months:   
    • Ohhh I see lol To be honest the main reason why I wanted to start modding is because of a business trip to Japan and Indonesia. I saw many cool and modded cars all throughout in these countries, especially Japan. I myself am of Chinese+Japanese nationality and when living in china (never lived in Japan js my dad side lol) I remember staring at these cars pass by with their loud tacky exhausts and insane wide body kits. And when I went back to Japan, I got even more invested even asking people about their cars and why they modded. Most gave similar answers to what you said but funny enough one guy just said that he saw the need for speed movie being filmed once in Tokyo I think near Shibuya Crossing and got inspired to tune and mod. After that I just started to fantasize on owning a car like that. Also tbh I prefer the R32 over the R34 it's just the R34 is more iconic lol (also apparently better aftermarket support than the R32) and my only goal really is just to make the car mine and make it fun to drive. As much as I love my Cayenne it's pretty bland to drive. Sure the interior is nice and pretty, gives you attention yada yada but I've wanted to experience what it is like to have a car that is truly yours. I suppose thats the goal so far. Haha if you find where I'm from, then sure. Ill help you out on your next "financial decision"
