Need Help: Pinging

[DezertEagle]

I got hold of a turbosmart boost controller, the bleed vavle style ones, I've put the boost up around 2 - 3 psi and I cant rev past 5000rpm!!!! It pings too much!!!! :ghost:

My mods are:

3" Mandrel bent cat back exhaust

Pod Air Filter

What should I do to recitfy the problem? (Please dont say put the boost back down, coz then it defeats the purpose of modifying it doesnt it! duh!)

Thanks guys!

[PranK]

put the boost back down til you get an intercooler.

or, get an air box to lower your intake temps....

but either way, a 2 psi increase (bringing it to around 9/10psi) causing detonation with those mods is pretty bad.

[DezertEagle]

Do you reckon octane booster would help in anyway? It says "Stops pinging" but I'm lead to believe this may just be advertising

[PranK]

it can help - what fuel are you using normally?

[DezertEagle]

BP Ultimate, I remember it used to ping when I really gave it on stock boost :S

[Tosh]

what Christian said,

turn the boost down until you get a FMIC and a cold air intake system (either ducting from the front bar into a modified airbox or whatever else you come up with).

whats more important to you??? having a car that drives reliably or a sick hectic motor that'll shit itself sooner rather than later?

[DezertEagle]

Since you've put it so well - Sick hektic - Hahahaha joking joking

Yeh I just found out I've done 15,000kms since buying the car in which I dont know when the Sparkies have been changed so they will be changed soon.

Are Iridium plugs really worth the $16 each asking price??

[Tosh]

yeh mate.

but in all honesty a FULL service should have been the first thing you did when buying the car.. unless there's a log book history of it being done in a reasonable time frame

I had nfi when anything on my car was done so we did everything the week I got it

If your car is pinging like mad with 2psi extra you've got some *big* problems.

Are you sure its not a missfire? Thats much more common at 5000rpm, do a search, there are heaps of suggestions for solutions.

[Blitz]

From experience, prolonged use of octane boost will stuff your plugs, a real pain especially if you have forked out for iridiums.

As with what Prank said, if you are pinging with such a small increase in boost, that is defiantely a cause for concern and I would bet that there is something else going on. My advice is get the car to a reputable workshop asap for a complete checkup before things really go pear shaped.

[DezertEagle]

Well this is my conclusion:

Since I've only just recently purchased my car it is evident I have NFI of the condition of my plugs. I will purchase 6 Iridium Plugs, new leads and retard the timing slightly

[BU5TER]

mate don't purchase leads, RB;s use igniters packs not coil and leads

Do a *full* service on it. Including Dyno tune / Power run - FIRST UP.

* Plugs

* Fuel Filter

* Oil Filter

* Air filter

* Oil

* Gearbox and Diff oil too

* Drain & Flush your radiator

* Cheack your fuel pressure

* Make sure you have no vaccuum leaks or pipe leaks - ie intercooler piping etc

Do not attempt to increase boost / power without knowing where you are starting from. ie get a baseline.

Do a compression test / leakdown test also. Just to be sure and for a baseline.

Plan your mods - do them bit at a time and get dyno results between mods.

Do not use octane boost to fix continual pinging.

Report back here with your progress and we will keep advising you.

You should be able to run 2-3 PSI on top of stock without any problems - bit get a bigger intercooler to be sure - a GTR cooler for example.

Hope it all goes well

When all else fails a 50 HP shot of NOS should fix your pinging

Cheers,

[DezertEagle]

Will be Iridium Plugs tomorrow, will let everyone know the result

Buster, I totally forgot about that! haha long days at uni

B-Man, Nos you SAY? Say hello to my little friend hahaha

I would suggest having your timing belt changed also, espically if your car is getting towards the 100,000kms mark.

Are you running an aftermarket boost gauge? sounds like a dumb question... but the stock one is not worth much I found.

Cheers.

[DezertEagle]

A turbosmart boost controller, like the bleed valve style ones.

I've been reading in some of the other threads round here the stock GTSt fuel pump is maxed out with only slight increases in power demand? Surely it can handle more then that....

[Majanal]

not controller, gauge. Do you have an aftermarket gauge?

[DezertEagle]

Oh sorry, nah just the stocker one in the dash that goes up to 1Bar

[Majanal]

I would be careful with that one... I first installed the boost controller (as I just couldn't wait to feel that bigger boost) even though I had the boost guage there ready to go... took it for a spin with what we guessed to be about 0.8 - 0.9 bar, was sitting just off the line with the +7 on the dash. Went like gold, but missed at around 4500-5000 rpm. installed a boost guage and it read 1.45 bar... hence the miss!

Just be careful and even see if you can borrow a guage of someone just to set your boost!

[DezertEagle]

OMG!!!! Ok now I'm scared, cause mine is doing the same thing, its on about 0.7 - 0.8 bar EEK!!!!

When you say missed, do you mean you heard the mechanical pinging noises???
