Tyres stopped chirping

[levymetal]

Gentlemen,

This is a stupid question, but I thought maybe someone would have some ideas about it. My car has a stage 2 shift kit, which shifts pretty damn hard. Basically, when I bought the car, it used to always chirp from first to second on hardish acceleration, on nearly every road surface. I don't push my car hard that often, however I have noticed that it no longer chirps any more. The shifts still feel hard though from what I can tell... I'm just trying to figure out if it would more likely be a transmission issue, or a tyre issue (eg, tyres getting old or something). I haven't serviced the transmission since I've had the car (1 year), and I don't know when it was done before that. The tyres are also a year old as well. Any ideas?

It's been winter time , they will chirp again when the roads are hot

its clearly because you converted it to gas........










just kidding

I was gonna say that lol, but he may have taken it as a personal attack.

It maybe worn tires or tranny may need a service again, also if you got the stage 2 shift kit put in it would have been serviced then.

Could also be abit more backlash in the diffgears or bushes worn so the ass end would be abit sloppy, or just lost power could be a number of things.
You should be happy that it only chirps and doesnt skip 20kph

Converting to gas doesn't equal less performance. Although it often does for example because gas shops often like to tune systems on the lean side, to give an impression that you have better economy than you really do.

It also depends on the design of the gas converter installed (often too-small ones are installed to save money) and the gas mixer (some flow better than others).

The reality is, gas runs on a carby style setup. The computer ONLY controls spark, not fuel, when on gas. You need it tuned on the rich side for optimal performance, at all times of day and year.

Also, having a gas tank in the boot, just above the rear axle, in my experience, improves the handling and rear traction of VNs and VPs.

Having so much performance on petrol with no gas tank just causes the rear end to spin if you have stock base model suspension and diff.


Also, running gas off a petrol spark map in the computer, results in non-optimal performance on gas, in terms of spark.

Likewise, if I put a gas tune into a stock petrol car, the petrol would run badly - low on power.

Checked your tyre pressure lately?

If I have the 205/15's on the car it chirps and smokes and dose all kinds of stupid stuff.

225/16's have fixed that issue. Also I find different road surfaces can chirp better than others.

haha well it used to chirp, even after i had gas put in . shift kit was already in when i bought the car too. haven't checked the pressure actually, mine do that tonight. i think i should buy some new tyres anyway though, considering mine still have flat spots in them. highway max's would be good, and they're 215s i think, as opposed to my 205s. almost as good as yours shane . i don't think i can get them on the mornington peninsula though. and i can't wait till the roads warm up

Highways wont chirp unless you are on reallllllly good hotmix, they are stealth

One would be forgiven for thinking this thread was a birdcage.

[levymetal]

oh that's not too bad, i don't really mind if they don't, i just always think that something is wrong when it starts acting different

Mine dont chirp, Car just goes sideways when mine shifts... They spin nicely.
