idle revvvvvss any ides?


TRD3000GT

Recommended Posts

There is a way of doing this by bypassing the throttle butterfly with some extra air and setting your idle with a vv. There is a lot of info on supraforums about it. If you cant find it then pm me or post and ill try to dig it up, i would post a link but dont know how. The other way is using the screw on the throttle cable but i really dont like that way of doing it and can cause rev fluctuation.

Chris dont be too quick to raise that idle, I wouldnt mind hearing what yours sounds like as it is, against what mine sounds like, see if there is much difference from car to car, and then what it sounds like once you have raised the idle.

 

What do you reckon.....

We now have a new-age transformer....

 

(in the tune of the old cartoon)

 

"Transformers, Supra's in disguise"........

 

One minute its a Supra, open doors, fold inside, flip open bonnet, twist, and its now a tractor.......

do u remember what the car transformer was called? its quite funny in a childish sort of way :)

 

my light fly is generally quiet, the box will rattle on occasion tho, but then again i sat and watched so i made sure leon didnt swap in a massey ferguson 6000 diesel lump :)

My flywheel is generally ok while driving round town, it doesnt tend to rattle very much at all, but take it for a spin down the motorway, then your know about it next time you stop at some lights.

 

Havent a clue what the hell that transformer was called, but wait for it, Im sure someone will know........

the stock fly is 36lbs, lightened about 14lbs, a reasonable saving in its self but consider on top of that its rotating.

 

takes away a bit of the refinement (who cares), rev matching on changedowns r easy, revs quicker, loses revs quicker, get on boost a bit quicker and, its been doubted, but to me its gotta free up a few lost horses. i love it and wouldnt be without it. some cars rattle like hell others dont.

 

jun do a lovely chromoly fly for the n/a :)

do bear in mind its a VVTi, I went to point out the throttle stop adjuster but it wasnt there.

 

It really does sound like a load of bolts being shaken around in a tin, it really is that loud. Going through London you certainly knew which car was beside you in the traffic jams.

 

I would certainly suggest comparing the sounds as if thats what the aftermarket clutches sound like theres going to be less people interested in them

That's why I went for a stock clutch plate, uprated pressure plate and stock flywheel.

 

Expensive mistake if you can't stand the noise (and probably don't need the clamping force anyway).

Lets not all start bashing uprated clutches and flywheels, as its down to the individual.

 

The biggest disapointment in my eyes about having this setup, is if you dont want your car to make a noise like a tractor at the lights you have to sit there with your foot on the clutch, because it doesnt make a noise then.

 

As for clamping force, and do we really need it. Well in my eyes yeah, as I will be attending more track days, and I do luv a burn off a set of lights with another motor, and when wet, maybe a few doughnuts. So with all that, its nice to know that my clutch will no longer fail on me, as its good for +600bhp, it bites twice as quick as normal clutches, so you'll be seeing my boot when the lights go green, before anyone elses clutch is engaged (anyone who has one, knows when you forgot you have this clutch and lift off too quick, you seriously nearly loose your head clean off), and the best part is, it doesnt matter how hard I am with the clutch and flywheel, because if it falls apart, its re-buildable, so it saves cost in the future.

 

Plus it allows the engine to rev and drop quicker and as someone else said, it has to free up a few horses.

 

As I say mine barely makes a noise in normal driving, so not sure how hard Chris' was driven, but if its anything to go by our last meet, Im not surprised his flywheel was rattling.

 

Thats why I dont want him to turn his idle up yet, I want to compare to see how much off a difference there is from car to car.

 

The way I see it is, if you can put up with a bit of noise, it certainly makes my car feel a whole lot racey. It makes me realise now why it must be so hard to get a F1 car going, as the clutches on those must be a comlpete nightmare, hence why their so easy to stall. I let my mate have a go in the Supe the other day, he made it 20 yards down the road, stalled it 3 times and gave up. There is a "nack".

 

Great piece of kit in my eyes.........

Guys this noise goes away a 1200 rpm. Also it should only do it when the car/box is hot, not from cold. You do not want to sit with your foot on the clutch too much, it's not good for the crank.

 

LW flywheels are excellent IMHO. The noise is a downside but you can overcome it. Chris not sure where the ISCV is on a VVTi. Probably half way down the inlet, cam cover side. Pull the connector & see.

I dont, it doesnt bother me what people think, have had people say "all that sounds rough".

 

But good point, I didnt really state that properly, the only times it rattles on my car is at idle, and when the revs are between 1500-1800, how hot it is will depend on how much it rattles at idle.

 

And mine still rattles even when the car is cold, thats the rattle as the rev limiter climbs past the 1500 - 1800 mark, your right about it not rattling at idle when cold though.

 

And I thought it would have ben worse on clutch/gearbox sitting in traffic with your foot on the clutch, why crank ????

Do a search on Supraforums for 'Crank Walk' (won't have to look too far) the guys suspect that a lot of the problem was down to, too many starts and stops of the engine. In the US you have to put the clutch down to start the car, its a dumb yank protection device.

I'll bash you, if you keep picking specifics. :twak: (meant in a :p way).

 

I was talking as though we were in a group, different people with different ways of reading/interperating and discussing, what more can I say.

 

Although I dont see your point ?????

I have heard competition clutches before and Chris's one is worse than that. I can accept a certain level of noise (I ran CW race spec brake pads for 2 years :) ), but I would not put up with the level of noise Chris gets.

 

Would like to hear them compared to see if Chris's is exceptionally loud.

Is that to eliminate the accidental incident of the keys turning themself. What does it solve ????

Mind you Gavin - he probably felt much better having read this - it being so helpful and all to the original question!:(
