Because they are better...

Maybe to some people but honestly not for me. I am happy with my RB26 and i would have never considered an LS1 when doing my engine swap.

If they were that good Reece McGregor would have ditched trhe RB26 and put a V8 into his GTR but something tells me the mid 7 he runs with his RB is more than adequate :D

I wonder how many seconds you'd get with infinite boost before you did the headgasket or put a hole in a piston.

Any one keen to try it out? : D

With a good tune i think you may be surprised. The exhaust wheel would probably give up before the engine i reckon

How do you tune for infinite boost? On a stock turbo maybe. But on a steel wheeled turbo, all overboosting is going to do is super-heat the intake air and cause detonation.

How does anyone tune a Pro Turbo car when they run 50psi+. Takes a fair bit of knowledge and some skill to do it right the first time, but its done on a daily basis now so its not impossible

There would obviously be limitations to the stock bolt ons, but lets assume they have been changed to cope i am sure the engine would last longer than most would expect.

OK, RB26 vs LS1 is a little different as the RB26 is paired with a pretty good 4WD system. If someone were to figure out how to pair ATTESA with an all alloy V8 only purists would stick with the RB26 :)

Infinite boost is infinite air, so you would simply need infinite fuel :laugh:

thats why i said get a nistune board and a tune, i'm fairly certain the standard injectors and fuel pump could supply enough fuel for 15psi...

my injectors were nearly at peak duty on 0.98bar so i believe im right about 15 on stock killing the engine. let alone stock turbo.

I say stop being a blouse and pick something faster to aim for. A stock LS1 is just a boat anchor and i dont know why anyone would want a Skyline being compared with one.

Why not choose a Veyron, or a Koenigsegg CCXR. Surely this sort of performance would be a lot more appealing :D

I had to laugh at this though..... clearly our laws arent doing enough and obviously do need some reform.... ie school kids should stick to a PS3 and GT5 and most certainly should not be let loose in even a stock Skyline, let alone a modified one.

"I have been on P plates for 3 years now but in less than a month I will graduate to my full license. I know the majority of people on here agree with keeping P platers out of high powered cars is a good idea and I cant say i disagree. But these laws definitley need an overhaul, it is clear that the people who came up with these laws don't know much about cars and as such, shouldn't have been put in charge."

Oh and this is absolute GOLD!!!!!

"The reality of weather you should be in a high powered vehicle or not comes down to your attitude, not your age."

Not that i would think you could be bothered to read through that garbage but it just got worse and worse lol.

Yeh when you set a boost controller to 50psi, that's different than just letting the wastegate free-boost.

Infinite boost is infinite air, so you would simply need infinite fuel :laugh:

And timing? :P Boost does not = air volume.

I dont think the 6.0L v8 is going to get beaten with only $1000 spent on the rb,

theres too much torque and outright nasty grunt , i really think you'd need a gt30 to hose one off convincingly

even if you have enough power , how good are you at launching the thing?? if you dont get a sweet launch then your toast!!

and if the v8 recieves some cams and extractors and tune, then just give up lol, or spent some big money..:whistling:

remember you'll lose your licence if you do 30k's over speed limit which is too easy ...pinch.gif

I was gonna say, what if your competitors' V8 had any amount of money sunk into it? It's a pretty steep uphill battle!

You're just comparing the engines. You forget they happened to put them into an outright oil-tanker of a car.

As previously mentioned, the R8 is not a bad area to set the bar at. The VX runs what, 13-flat? Easily achievable in a mildly modified Skyline.

    • For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
