Woo Hoo Dump Pipe Finially Arrived


Recommended Posts

meggala,  

when I tried to turn my boost down all the way (I turned the bleed valve until it was shut), I went for a drive and the car was terrible, as if if had no power at all, boost was really low (shouldn't it just go to 0.5bar?)

dunno what to do?

It still runs ok (quicker than standard) on 10psi, but my point is that it lost some power when I put the dump on. I might as well put my standard cast dump pipe on for a power increase? :(  

But seriously,  if I get it on a dyno and it shows that it has timing and fuel probs, is there anything that can be done to iron it out before I get an SAFC?

man man man, get your car on the dyno at ice on saturday and get everything checked out!

If u have lost power by putting on your dump then your car must be irish not japanese!

turned boost back down to normal (got rid of bleed valve) and it runs smooth as, I've come to the conclusion that:

1. before dump I had it at 11psi and it was pretty smooth b/c it wasn't getting too much air so A/F ratios weren't too bad

2. After putting dump in, it's letting so much more air flow through that combined with boost the stock ecu sh*ts itself and give me massive flat spots.

In other words I will wait before I get my SAFC before I put my bleed valve back in.

I need help with one thing though!!!!!

After installing the dump, I've noticed that I get really big spikes, even with the stock boost set up back together. It spikes around 3psi which I was never getting when I didn't have the dump - Can Anyone Help Explain this?

I though it might be the type of dump I got b/c it has 2 seperate pipes and the wastegate pipe is only 1 1/4 inch diameter. Don't know if it flows enough for the wastegate, meaning that the turbo can't bypass all the pressure when at high revs and it spikes.  

Is it something else.

Help appreciated.

Thanks guys (sorry 4 such a long one!)

The wastegate pipe aint 2 small, look at franks hks dump, its the same size!

black r33 wind your boost down a bit and see if it help wind it down to 8 psi or so more boost doesn't nessacarliy maen more power then get the s-afc tuned.

franks here in melbourne we have had some very good results with the s-afc tuning 15 20 rwkw iis gain quite often.

exstatic doesn't need to jsut ify the gain cause most of us were there when he got the gains and saw them with our own eyes

Arrgh if only i knew exactly what and where to get for my exhaust

I'm after a Front pipe + Dump pipe

3 of my local exhaust places know jack squat and i've just emailed UAS hoping for a half-decent reply but know it will cost the earth through them.

Benm, i just ordered a dump from JMS (japanese motorsport) in Adelaide and am waiting for it to arrive. They have stainless dump and front pipes for a reasonable price. I'll post some pics when it arrives and can let you know what the quality is like.

    • Yeah I understand you have to pay for an updated map or subscription service or something. But I can't even find a current map for Australia. My map is dated 2017, but didn't this car version still sell in Australia until 2021?   Also, just as an aside, the navigation system warns you of traffic incidences ahead.....why would they include that on a map they knew is not receiving live information. I am forever going to be warned of an incident that probably existed for 30 minutes 8 years ago.

    • sensible choice....and all 32s should be in yellow
    • Run it in open loop for now, and drop the frequency down. This lowers the resolution and requires more duty cycle to do anything, however good to troubleshoot.
    • According to Josh, one of our local Americans, it seems the USA still can't get turbo systems quite right at a lot of places, so possible that they're not running great at all, but they've just not complained as NFI about getting it right...
