Car Not Reaching Full Throttle

[Hanaldo]

Hey all,

I installed a vacuum gauge on my car about 2 months ago, and noticed it never reaches 0 when i put my foot flat to the floor. It usually stops at about 5, and i read recently that this could be due to free-play in my throttle, restricting pressure. Does anyone know how to check and correct this?

Cheers,

Martin

nah doubt it, id say thats a shitty gauge id say!

maybe check the cable in the engine bay. get a mate to put 'pedal to the metal' when the cars off, and see if the cable actually (mechanically) opens the throttle full. at full accelerator, try and open the throttle more, if you can, youve got an adjustment/cable sretch problem...

or maybe...

i dunno but do neo RB25s have some sorta traction control that partially closes the throttle under wheel spin/very aggressive acceleration?

i know 1js and 2js do...

[Hanaldo]

I have never lost traction so i wouldn't know, but through all the gears the gauge only reads up to 5, so i doubt it would be a traction control thing... I also put it down to the inaccuracy of the gauge, but after reading that there are a surprising amount of cars out there that don't ever reach full throttle i thought it may be worth checking out, i wouldn't be surprised if on an 11 year old car some play had developed in the throttle

Turn off TCS

Also get a turbo .

You're doing something wrong then.

You're doing something wrong then.

Leave the poor guy alone.... Its hard to lose traction with 100 NA hp's!

Was waiting for the NA jokes.... Quiet Tom, just cause you car has probably 3x the HP Hanaldo's has

[Hanaldo]

Lol yeh i was waiting for them also. Doesn't bug me lol, i give myself shit for an na Skyline... But atleast im driving my favourite car and not some bunky commodore or excel, plus my car is in better condition than a lot of other Skylines on this forum, so tease all you want

My car doesn't have a switch for traction control, so if it has it then i can't turn it off. Not interested in thrashing the Skyline either, if im going to do a skid then it will be in my other car.

By my estimations, if i had a turbo running 5psi then i would only then be reaching 0 vacuum Might as well fix this problem and pretend i installed a supercharger Ahhh the imagination... Bliss for NA car owners alike.

P.S. My comment about excels was not intended to be offensive. Excels excel in excellence.

Not sure about N/A Neos but the turbo Neos have like a secondary throttle for TCS that sits immediately before the main throttle.

Even my Stag has the casting but it is empty.

[Hanaldo]

Well i got my mate to put his foot flat to the floor and there was a little bit of play in the throttle, so i got my mechanic to sort that out, and now the gauge reads up to 2. Mechanic said thats likely to be inaccuracy of the gauge, so problem sorted

Thanks for the suggestions those who actually said something useful lol

whats wrong with NA? lol i drive an NA R33 before, quite enjoy riding with it tho. Only certain level you just feel that's wouldn't enough for you. Yet, i believe NA R34 which come with the neo rb20de would be powerful than the NA R33?

[DR1FT4]

i didnt get a turbo for the speed i got it for the pssshhhhhh sounds it makes, and wanting to check vacuum on a N/A?

[Hanaldo]

Lol ^ You should've just got one of those turbo whistlers, far cheaper. Have you seen their slogan? "Real turbocharger kit = $3000 + installation. Turbo whistler = $19.95... Which one would you buy?". And then you could buy one of those electronic blow off valves.

Lol im pretty sure my car has a neo RB25DE, so thats a bonus on the RB20 I fuckin love my car, im perfectly happy with it. Someone else always owns a better car than yours, so im very happy being 18 and owning the car i do

Yeah true. When I was 18 an N/A R34 would have been a dream come true, otoh if you ever drive a turbo and really give it some you won't want to go back.

That's the way to look at it. Be happy with what you got.

I'm very happy with my auto slug-box 33, especially after driving the corolla.

EDIT:

Excels excel in excellence.

Sorry but that is just not true...

I drove Tom's GTR... Yeh i want one. Almost sold my 34 and bought one. Decided i would rather have a nice clean car then a bunky fast car, especially when i know it would get me into trouble. Ill buy a 34 GTR as a reward for graduating uni when i do, holding myself to that as well.

Lol i was being very very sarcastic about the excels lol... although i know of a 10 second one. But that doesn't count because the only thing that is still orginial Excel is the shell, its got a Turbo 5.2L Chev V8 in it... Yeh fast

Damn you must be rich to think about buying a 34 GTR after graduation. What are they 50k?

Yeah could get you in trouble you are right, but same for everyone.

[Hanaldo]

Lol nah, im just stubborn and would rather have the car than anything else

[Yaah31]

yea i agree with martin would rather have a nice looking car wit ha bit of boot than a fast shity looking one but thats my opinion
