Intercoolers

[rob77]

Guys,

I went out lastnight at around 8pm, seemed fairly coolish so I set the EBC to 0.8bar andway was giving it a bit of stick and the car started to detonate. So as soon as it did I took my foot off the accelerator and dropped the boost to 0.6bar. A few guys run bleed valves and stock I/C's do you guys detonate as well?

[rev210]

NO.

I can and have run 1bar without any for a quick blast, I did this once never again (just in case)

[red17]

Rob, im sure you know my story about running on 0.8 bar. So no need to enlighten you any further.

In general, unless it was 2 in the morning in the middle of winter, i wouldnt do it.

It will depend on the car, I ran 1bar on my stocker with no troubles, but in general unless you have tuned the fuleing to suit that boost then I would steer clear. On a stock turbo running 1 bar means that the pressure at the turbo is far higher, and it just ends up producing heat, which is what causes the detonation. Get a FMIC and 1bar is no probs.

See'ya:burnout:

Hey just because you detonate doesnt mean its your intercooler, there are so many different variables here....But u would assume its because of the heat of the inlet air!

If you retarded your timing slightly it may stop or even gap your plags a little bit closer again

[rev210]

Not the intercooler!

plugs too hot? (go a colder set)

Too much timing?

wot r u refering to?

Too much timing u say? u say he runs standard?

Skys ecu is tuned for 100ron and u think that RON98 is really 98 points?

Not as far as people tell me its not!

So hes pinging either like he said, cooler not being efficient, a little bit too much timing in the higher revs, plugs not gapped properly causing combustion chamber to preignite because of the large gap that the coil has to generate a spark.....and more..

Check the pressure drop across your core see how how much boost your really makin to get 1 bar out the other side of a GTS

core, thats why the airs so hot.

[rob77]

I know the consequences of running too much boost and high intake temps... what I dont understand is why so many people persist with bleed valves and stock coolers. With bleed valves it will spike to probably more than 1 bar and is hardly as controllable as a EBC. Just wandered how many people did it and why?

[Jay95R33]

1 bar on stock cooler = interHEATER !!!

But he is running .8 ba and has pinging.

Check everything out and get it looked at, plugs, filter, timing, fuel filter, fuel preasure blah blah blah....

Have you had a service done recently??

What are we actually talking about?

Everyone knows tht the stock IC on an R33 gives about 6psi drop over 15psi equalling about 21psi of course the IC is saturated and causing a huge pressure drop and heat increase but we are talking about other variables here.......none of this is extra ordinary :eek: :eek: :eek: :eek:

[skyzerr33]

i run bleeder atm on 11psi

it has never spiked as far as i'm aware.

but i got a fmic

go figure

[rob77]

Do you have a boost gauge? or was it dyno'd to 11psi and set?

[skyzerr33]

set off boost gauge

[rev210]

I have a bleeder/spiker, they suck!

Mind you I only run 10psi.

U like to point out u only run 10psi hey....

girl! :lol:

No...but I'm thinking I should now.

Yes, there must be something to enjoy about pointing out the fact that you 'only run 10psi'.

Perhaps its the way you point it out?

You can say it:

..with contempory dance.

..with an artistic arrangement of pocket lint.

..in music,that when played backwards says ' I only run 10psi'

..by cross promoting with Mac Donalds, the '10psi burger' - guarenteed to produce flatulence at or below 10psi.

[rob77]

He only likes saying "only 10psi" cos he ran a 13.4 with only 10 psi... bastard!

My intercooler *may* be here this week, only taken 5 months to come from japan *laugh*. looooooong story
