no they don't. I've seen Chris's (MaximumSportZ) and they didn't have anything of the sort.

 

Well then I guess he's got "special" ones. Every set I've seen (four sets at GRD), and additionally mine have them.

Sharif will tell you it's normal too.

 

Brian, those sets were just all kicked around in the same shipment on the boat, mine wasn't.

 

My car is RHD, and my downpipes do not have the dents in.

APS are talking sh*t, the pipes fit RHD cars without any need for dents or other flaws in finish.

 

APS is usually full of ****. They usually put out good stuff (when they plan it out) but they have HORRIBLE customer support.

 

man this thread is great................

 

My 3.5" test pipes didn't have dents. If they indeed changed the "design" to fit RHD, then damnit they should just make a new set specifically for RHD Z's. Especially for the money they charge on all of their products.

 

 

 

Thats exactly it, my downpipes dont have dents in, and they fit RHD no probs. Its just a poor excuse for a faulty batch of their product.

 

Always nice when the manufacurer out right LIES to customers.

 

^^^^^
Another reason I backed out of my APS plans... Oh well. Great products 50% of the time. The other half of the spectrum falls into the complete garbage catagory. That coupled with the fact that APS customer service = non-existant

 

Hello,

It's threads like these that reassure me of our decision 2.5 years ago to not sell APS...

D.

 

the thread on motoring is much more entertaining than this one.. well thats because Peter is in that one

 

It's been a trip, lemme tell ya. Darren - what's your schedule like for UTEC tuning?

Back on topic:

Picked up the car from SRD yesterday - forgot to snap pictures but will do so today

New piping sounds stock - did two runs on the freeway last night:

1. BC off, running on wastegate pressure alone: 18.8 psi peak, 14.2 psi steady (using a 1 bar spring)
   
2. BC set to 20 psi: 23.3 psi peak, 19.8psi steady.

The ST now feels and sounds like a jetfighter at takeoff.

These were untuned runs and not throughout the entire range because it's running wayyyy too rich and I'm not sure what the consequences are of hammering it all the way to 7k, so I backed off at around 5.5 - 6k. I'll have dyno sheets tonight when I get back from DynoComp.

I ended up sacrificing the midpipe from the ST setup, which is now mended onto the 3½" section on ext. WG piping - SRD did a great job on the welding and it looks like it's straight from APS (with regards to quality/finish). There's very little clearance between the piping and frame rail and it does bump the floor on hard starts.

Seems my limitation at this point is the ECM - there's a UTEC upgrade in the near future. More to come this evening...

 

Don,

I bet. Just PM me when you're ready to bring her by. I shall see what the schedule looks like. Hope it works out for you w/ the APS in the mean time.

D.

 

show him the new setup...maybe don will also switch to the PowerLab kit

 

i still dont understand the boost drop, on my 240, using the turbo from aps for the single kit, boost hits 20 instantly and holds 20 until i let off, thats with a 14psi spring also. and yes, the turbo has great boost response and does sound like a jet at 20psi, well, mine seems a little louder due to the atmospheric dump. you gotta hurry and get it dynod and tuned.

 

Grrrr...

Seems that I may have gapped my plugs incorrectly or whatnot; tuner says he can't tune because of a flame-out situation. Gapped at 0.035" per APS, but I didn't take into consideration the extra fuel and air, so I'm told to bring it back next week with 0.028" gap. Currently, it's a smooth AFR until about 3500 rpms, then it starts to sawtooth and it dumps a huge amount of unburned gas (black smoke) out the back.

Good news though: Peaks to 22psi, and holds until redline at 20.5psi. Bad news is I have a 14.5psi spring and the BC set to 16psi, so I can't figure out how to reduce the boost aside from changing out the spring?

Making good power on the bottom end before it starts to flame-out: 300rwhp by 3750rpm; curve shows potential to swing into the upper 400's on pump gas.

EDIT: Tig - I have mine dumped open atmosphere also

Wish I had more to share - this'll have to wait until next week.

 

Funny thing is that if you were to do some research and real digging you would find out that some of the founders of APS are the same people who were blowing up some American cars a bunch of years ago under a different company name due to poor fitment and bad R&D.

This is why a few vendors who remember this have not sold APS.
