Does anyone Knows why?

[aleko69]

Hi there fellows, I,m having problems with me car at the moment, every time i change gears it coughs, I dont know if it's running to rich or to lean but it is very annoying to hear this! this started after the car came off the dyno 3 weeks ago .can anyone help me please? or heard of this happening before?

Prior to that , the car was running perfect, regards.

Ps: my ride is a R 34GT t. :confused:

mate

by cough do u mean backfire (popping noise)?

[aleko69]

yes, seems like popping !! not quiet back fire .

[SkyGTRline]

meh... Mine does it....

I think its mad..

[NJR 34GTT]

Sounds like the usual popping noise due to some excess fuel in the exhaust. Mine does it all the time, nothing at all to be concerned about.

Hey aleko69,

As others have said, I am surprised that you didn't have the excess fuel pop before.

What sort of dyno run was this. Tune or power only ?

Hi El Bee, it was just to find out what Kw it reached (power only).

I've never noticed the excess fuel pop before and I guess was worried after the dyno run.

Thanx for the reply, I feel alot better now!

The car clicked 234Kw... stock with factory ecu (impul) .

[aleko69]

Hi NJR thank for your quick reply , me mate said the same thing , but I just want it to make sure the was nothing wrong with my baby. as for your wheels , have u done any mods yet? any safe tips?

[Amaru]

Yep, as been said its just overfuelling slightly on gearchanges... do you have an atmospheric blow off valve or the stock one still?

[NJR 34GTT]

234kw at the rear wheels? Thats a very very high figure for a near stock GT-T. Where was the dyno run at? Sure you haven't got a GTR in disguise?

What colour is your GT-T? Keep seeing a few more around the place.

I've got all the basic mods and can't decide whether I can start the more expensive side with diminishing returns.

234Kw??? At the flywheel??? No way thats at the wheels without a new turbo and lots of the usual other goodies.

If that figure is right I can only presume its "stock" internally.

But yes the overfueling your experiencing is fine.

[Bluprint]

When Ed had a look over my Neo he did make a point to mention that it's a Nissan thing in general for them to run very rich at high revs, so it sounds normal to me as well.

234hp

[Bullet32]

You should hear the backfires I get every now and then.... *rumble rumble... POP!!!*

I love them, its normal and it sounds cool!

[aleko69]

thanx integra for your anwsers, and as for the valve it's a supersonic turbosmart

[aleko69]

Hey, it's true 234kw at the wheels and it is stock ,nothing done to it ,i've had it for a few months now. me car is silver but she seats in the garage most of the time.

[aleko69]

Hi R31 , i think i met u at the museum one friday nigth, the day before the dyno dayin fyshwick! rigth!!, his ride R33 gum met , and my silver 34. as for the popping !! annoys the ?<>out of me.

[NJR 34GTT]

A stock GT-T will pull about 160-170rwkw. Stock turbo and bolt on mods good for ~200rwkw. Anything above this will require upgraded turbo or high flow. No chance in hell that a stocker will ever reach 234kw. Either there are some serious goodies in that engine bay or your dyno figure is very optimistic.

Please don't think I'm trying to have a go at you, I'm just very curious as to how you got such a very high figure.

[aleko69]

men I got this figures from auto tech and believe me they are real!!!call peter and ask, i'm sure the figures haven't been erased just yet. anyway at the end of the day i'm not competing against no boby so be it.

[race_snooze]

yeah well some how i got 216rwkw out of my "stockish" 33 at the auto tech dyno, dyno's are not a real way of telling power they are made for tunning cars thats it!!!!!!!!

Sorry as for the poping mine pops like all crap and once and while it will shoot a flame
