Can't Boost In Hot Weather, Well Not The Usual Amount.

[WogsRus]

Hay guys, dam this hot weather, So dam hot it's not funny.

Anyway i have not been able to get higher then 12 psi on my stock turbo. Is this a heat issue? I have a FMIC, but 35 deg plus is ttoooo hot.

I readjusted the boost controller, but no good, can't get higher.

Is this a common problem. I have had no issues when cold, but today is the first hot day and hence my question.

[dead32]

i wouldnt be raising the boost in hot weather.. id be turning it down..

[MBS206]

When the air temp goes up, wind the boost down!

[WogsRus]

i know about the pinign and so forth, but mine is all good, got a knock light and so forth.

But i am just wondering if this a problem with heat more then anything

hey mate ive noticed in hot weather my car's turbo doesnt as well, but i think its because my pod filter is closed up, so i think the added heat makes it a problem, if u hav a pod try n get a heat shield that should fix the problem

Hey

I'm sure that you know that the car won't run very well in the heat (you do live in the heat after all, lol). Mine runs liek crap.

But in answer to your question, nah, the heat won't stop you running high boost.

It's most likely the boost controller you're using.

Just to give you an example. If you disconnected the vacuum line from the waste gate actuator - so just leave it out in the air, and floored it, it'd probably hit 50 psi or something (don't try it or you'll blow the turbo and maybe your engine.

[Ryanrb25]

the stock turbo runs outta puff after 12psi anyways, i dont know why you'd wanna try put it up boost on a bloody hot day aswell...i can see alot of people shaking their heads right about now. you said your well aware of pinging etc and you say its fine, but most of the time you cant hear it pinging.

[Taso84]

yea u can hear pinging, turn the stereo down and open the windows

[WogsRus]

she wasn't pining, well not till this morning, i added soem timming. Backed off REAL Quick.

This morning much cooler temps, but turbo still seams funny. I checked it and there is no shaft play, well no more then the specs say, all good there.

Going to check engine compresion to make sure.

I am using a gozzmo IBC. I am also going to put my 10 psi actuator back in, that seamed to work better.

I tell you what, these turbo cars make me VERY paranoid. Knock, ping, bang and so forht.

[r33_racer]

hence why you leave things on the safe side especially in summer. Lowers the chances of it going Knock, ping, bang and so forth.

If you wanna go nuts with boost and timing in summer chuck a water/meth injection kit on it.

[WogsRus]

Thanks mate, i am in the process of making up some FMIC cooler water kits, and possibly injection kits aswell. For now i just need to back of a bit. LOL

Also, how much differance does a heatrange change in a sparkplug make. I have BKR6EYA, but thinking of swapping to BKR7EYA.

The reason i want to do this, is that i have a Central 20 ecu, and has been tuned with safc to get correct air fuel ration and some timming knocked out, but i still get some ping, well i think anyway. So possibly going to a 7 hetrange plug could help a bit?

[MANWHORE]

What was wrong with the 10 psi actuator? I remember back when we were looking for them, you were so keen to get it?

Doesn't it hold boost properly etc?

Cheers

[WogsRus]

Nothign wrong with it, simply put the stock one back in to get the EBC tuned to that, problem is that my wastgate still is stock and couses creep. The 10 psi gate is much better, so i will be switching to it.

It works much better with the 10 psi gate, it is just for tunning purpouses for the EBC.

Main problem since the weeknd, lack of boost over 10-12 psi, well not lack of but harder to get to that level of boost.

So i'm gona do some more research

[r33_racer]

yeh a colder range plug will drop knock a little bit...but not alot. From memory from what cubes informed me ages ago it was equivalent to 1 degree of timing pulled out i think or something along those lines.

[WogsRus]

Thanks RACER, i'll give it a go tommorow night i think, see how i go.

I Tend to get paranoid about everything. LOL.

tune your ebc for cold AND hot. Does it have two settings? If so retune for both weather conditions as stuff like gain etc etc will be different for different temps

[Guilt-Toy]

why do you want to run more boost in hot weather? you will just blow it up

[WogsRus]

don't want to blow it up, the car is fine itself, just didn't know that there was so much differance in hot and cold weather.

anyways thanks
