Hey All,

I am tossing up between 2 dump pipes..

1) BOS IMPORTING

2) CES RACING

Who here has either of these and what was the power increase after install?

BOS IMPORTING one seems better value for money, but the CES one claims very good gains..

Opinions?

Cheers :laugh:

This is what I have at the moment, I am guessing it is stock?

the one my mate has is just the split dump pipe and its split for about 10-15cm. i'm just going dump only as the car came with a 3" front pipe and i can't see the point in spending $400 when i can get away with $150. if i didn't have a 3" front pipe i'd get one of the BOS ones.

screamers are illegal and can be bloody loud.

people dont seem to worry about screamer pipes as much as say no cat .. but the penalties are the same.

you shouldn't see any difference in spool times as this split system only really come into effect once the wastegate opens, therefore it is already at full boost.

noticed on my old setup that it would rev out much cleaner after the 5-5.5K rpm range ..

hey guys just wondering i just bought one of these split dump pipes but now i have gone for a high flowed turbo and has much more room behind the turbo in between the wastgate and the exaust . would it make a big difference if i dont have the little metal bit in between to seperate these two?

yes the little bit, or divider is half the point of a split dump. without the metal divider between the two they are still likely to cause excess backpressure.

imho a split dump without the divider is kinda pointless

i ought the split dump pipe from just jap and was told that it was for the hks turbo so i took it off and it is lost but looking at the gap on the high flowed turbo, it has plenty of room for the metal to split the pipes does anyone know when i can get just the spliter part from?

    • Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that 
    • Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

    • What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
    • While I was waiting for the new parts to come in for the charge pipe and radiator I decided to do some turbo modification. The drive pressure (exhaust backpressure) was a lot higher that I thought it should be. For 32lbs of boost drive was 55lbs. The turbine housing is a 1.10AR and my turbo builder has suggested to go to a 1.25AR. To test if a larger AR would do anything to reduce drive pressure AND not spend any money I decided to hog out the divider in my current housing. I removed it from the inlet and the whole way through the housing.  After reassembly and testing it doesn't look like this modification did anything for reducing drive pressure or requiring more fuel (making more power). Oh well, it was worth a shot. We'll get some data at the track if it makes it past the 60ft. I also machined a $7 shift knob off Amazon to fit my Stillway shifter since I didn't like the Stillway shift knob. Next on the list was the radiator replacement and fabrication of a new intercooler tube that had no silicon coupler. No pictures of this - I was short on time each night after work to get this done and didn't stop to take pictures.  Next was to get the clutch disks out and replaced. Previously when installing the dogbox I had ordered a set of the same sintered iron disks I had been running because I switched to the 26-spline input shaft. I thought it was odd that they didn't have any markings or brand name on them like all my old disks had but installed them anyway. At the track I could not get the clutch to lock up using my normal strategies. After two track nights I reached out to the clutch manufacturer and ask their thoughts. They said they had to switch the material out because they were having trouble getting the original material and that this new material would not take to being slipped very well.  So out with the first set of 26-spline disks and in with the correct material 26-spline disks. While I had the trans out I added an inspection/service hole. I've wanted one of these for a while. Now I can have a look at things and change the front cover shimming when needed (clutch wear). I hustled and got the clutch change done in a few hours on a Saturday. Hopped in the car and drove home. On the way home I did a 1-3 pull. When shifting from 2nd to 3rd the core plug in the back of the cylinder head popped out and dumped all the coolant. Thankfully I was only 30 seconds from home and coasted it there. Datalog showed nothing unusual and 2.5psi of coolant pressure. That plug has been in there since 1992 but I guess it worked its way out. Pulled the trans AGAIN and replaced the plug, JB welded it in, and made a brace. Also deleted the head drain I had added in during the bearing issue fiasco.  I am currently changing my boost control plumbing to make it cleaner. After that is done I'll make another attempt at getting past the 60.
