Heaps of carboun build-up on rear bumper...
« on: April 03, 2002, 08:52:35 AM »
Hey all.
I recently (about 1.5 weeks ago) got this full 3.7" TRUST Power Extreme II exhaust system with 3" TRUST down pipe and as you can see on attached pics that i already have quite a lot of carbon build-up on the bumper... Is there a way to prevent it? Anything?
And also: i heard that Apexi S-AFC could prevent big amounts of smoke coming out, is that true? Or just a thought?

Cheers

PS, Although when my gf was standin outside the car while i was doin some 0-100k times, she said that there was no smoke comin out of the exhaust... Hmmm.. weird... i think that its just backfirin that causes it.
btw, my best 0-100k time was 5.76 measured with Apexi RSM hehe :dfinger: :dfinger:

Exactly right mate. When i got my S-AFC tuned i was sitting in the boot to stop it wheel spinning, and first off without it tuned i could see lots of black smoke coming out. Then as they started tuning it less and less smoke came out, until there was only a tiny bit at redline.
Tuning the S-AFC makes it run a bit leaner which will give you more power and also stop the black carbon build up.

I have no such problems for two good reasons

1. My car is gunmetal :D

2. I have no boost :( :( :(

But I can all the Skylines my mates have all blow alot of black smoke during backfires etc.  I have heard proper tuning can get rid of it, but as a non-turbo owner I think it's cool.

I agree ... why fix the problem when you can just hide the evidence. :D

I don't have a problem with carbon build up on the rear of the car,  but there are a lot of fuel spots back there.........

Gets worse if you have the cat removed also, my car used to stay clean as untill I got the exhaust done, now it stains the hell out of the rear bumper.

Thanx for replies everybody :)
I used to have a gunmetal grey R33 GTS25t before, but it didnt smoke as much as it only had 2.5" straight through system. And NO i aint changin colours, cause i love this white sky of mine! :dfinger:

Ethan_R33,
i will deffinitely get Apexi S-AFC then... dont want any more carbon build up on the bumber, or i'll just have to repaint the whole bumper :) does it take long to tune the S-AFC? How much is it? I believe around NZ$600?

Cheers

Hey Nitro, lookin at your pics I am sure a little adjustment of your rear muffler [down and out ] would solve the problem. Compare yours with mine,I have no problem.

You could always fit one of those aluminium sheilds - Easy to clean and they do look good on certain cars:)

Nitro, it took about 1 hour to tune it and change the base timing.
I got it for $450AUD, and it was $150AUD to tune it.
