Perhaps with the extra boost and extra acceleration, the thing is revving out quicker and even higher. (assuming you are not bouncing the thing off rev limiters as a shift point.

So if you are normally changing gear at 6,500rpm in 2nd because acceleration is starting to trail off, but with more boost there may be a little more top end, so you rev the car that couple of hundred rpm harder.

Go for a drive down the street at 7psi and bounce the thing of the rev limiter, then do it again at 10psi...you will see that your road speeds are the same.

I am a mechanical engineer...

You aint no mechanical engineer, you explained that concept far too well to be a mech engineer... there werent even any typos or speling mistaks :rant:

I like your point, but were not talking about a 5 or 10 km/h difference, we're talking about a full 20km/h difference. I never hit rev limiter, only ever hit it once, i always shift at 6500... My Apexi computer even tells me that. So its not just a guess of when i actually shifted.

Oww and i dont shift at 6500 because im loosing power, im shifting at it because its peak power right there and its the best time to shift.

"more boost there may be a little more top end, so you rev the car that couple of hundred rpm harder." Yeh good point, but a couple extra hundred RPM wouldnt explain for a whole 20km/h. Dont worry, I'll be testing tomorrow.

/me awaits Sydneykid to tell me I'm wrong.../

Your WRONG Ronin, I have a son but he is neither long nor lost. :slap:

As for Jamesh3, I have seriously pissed my pants several times reading the drivel :bonk:

In a manual car there is a SOLID connection between the wheels and the engine. In the same gear it is impossible for the rpm of the wheels to change if the rpm of the engine doesn't. :flamer:

As for single, double or triple clutching on the up change being faster, I can not believe anyone is that stupid :headspin:

How long does it take you to;

lift off the throttle

push the clutch in

move the gear lever to neutral

push the clutch in

squeeze the throttle

lift off the throttle

then move the gear lever into the next gear

lift off the clutch

squeeze the throttle

If you are really good it's 0.15 of a second.

Compare that to;

lift throttle

move gear lever into the next gear

squeeze throttle

If you are average that's 0.02 of a second

In a 1/4 you make 3 gear changes, 1 to 2, 2 to 3 and 3 to 4. Using the double clutch method you spend 3 X 0.15 = 0.45 not accelerating. Compared to 0.02 X 3 = 0.06 not accelerating.

You just lost the drag by 0.4 second. :kick:

I can't believe I managed to type this without laughing my self sick. :throwup:

Wrong. Thats like truck double clutching. Not Racing double clutching... Doop!

Firstly Read post #27 & #24.

Lol mate, thats the other form of Double Clutching most people think when they hear that term. You are ignorant like many others,i dont blame you but perhaps you should read posts 27 & 24 about Double Clutching which you've probably never even heard of before then read another about "Popping" & "Fanning" which is the same thing... Once you have finally read the post and then know why double clutching is faster for turbo cars, you may be the once laughing at your self.

"I can not believe anyone is that stupid"

Ignorance is Bliss aint it! :flamed: hahah

You got that one pretty much spot on, well explained...  It's also called double clutching by people, it seems the term 'double clutching' has 2 different explanations and most people think the other.  From now on so theres no confusion i hope I'll be calling it "fanning" or "stepping" or "popping" hehehe.

NO, double clutching does not have two explanations!

NO, fanning, stepping or popping is not the same as double clutching!

Whoever these "most people" are, they are wrong and have misinformed you! this is cause most people dont know sh1it about cars.

How many reaplies does it take on here for you to believe what double clutching actually is??? just accept it: you are wrong, and so are most people

**this is a perfect example of someone thinking they know all about driving a car fast just cause they drive a fast car**

in simple terms, i've always thought of double clutching as a longer period between each gear change, hence, less accelerating. Why spend more time changing gears? doesn't make sense at all :confused: I think SydneyKid explained it very well.

When i see someone taking the Mines R34 GTR out for a spin, or any track battle of ANY turbo car, and see someone "double clutching" (as they have a cam view of the pedals) i will come back to this thread and say i'm wrong. But as long as the crazy nutcases in Japan are flying around in beasts of cars like the Mines R34 GTR, and shifting "normally" i will continue to think of "double cluthing" as something that belongs, and should stay in, the Fast and the Fubarb.

cheers :D

OH MY GOD!!!!

I DONT THINK THAT ANYONE HAS EVER TOLD SYDNEYKID THAT HE IS WRONG!!!

YOU KNOW WHY?

CAUSE HE IS NEVER WRONG!!! NO EXCEPTIONS!

Well I tell him he is wrong all day long.....

But online, this is not the first time... won't be the last, but might be the  funniest :headspin:  

dont you think its strange that you are the only odd one out here?

/me runs into corner and cries... shut down by Sydneykid  :D /

Can the REAL Son of Sydneykid please stand up.....

:wavey:

That's right, been here all along......

Don't diss la

Wrong.  Thats like truck double clutching.  Not Racing double clutching... Doop!

:bs!:

guys i figured out why he gets higher speed with higher boost! :D

he's using tyres that expand when they heat up (some drag cars have this?). with the extra power he's getting, with the added excitement that he's gonna "double clutch" like in the movies, he performs his (incorrectly named) double clutching in each gear, he's spinning the wheels and getting another few cms diamater in the tyres with more heat than he could with the less power, therefore high speed in 2nd gear!!

(as for "granny shifting" claims, as if ur granny shifting ur not even really reaching full boost before changing, i dont see how he's getting 0-100 in 6s with that, man imagine the car when it hits full boost!!)

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
