Happy Boosting............. !

 

Hey Moose, PM me and lets see if we can hook up. Scarface is also here in Dubai, the 3 of us could get together.

 

Mine works great. 400+ rwhp and still very streetable when driven under 3k rpms. Any specifics you guys would like to know?

 

hi all of you from dubai,,,,,we got 1 kit APS ST in ABU DHABI and masood dealer fix it one of the car but the light of VDC(off) and slip on. and dealer couldnt solve it,so you have to keep hold on befor you buy cause that guy now in dubai,he try alot of shops but non of them solve the prob,,,there is vortech SC with masood dealer they sell it for 15000 dhs with install will bee totall18000 dhs with warrenty of car,,,you can check with them.

 

kopo - how'd you get over 400whp? what other mods (beyond whats in the kit)?

ahm

 

I'm pretty sure he just has the APS plenum, upgraded wastegate actuator, and custom tuning.

 

IF WHAT YOU ARE SAYING IS TRUE...I WILL DROP MY CAR OFF TO THE DEALER NEXT SATURDAY...
i am impressed...
just for you guys to know 18000 dhs= 4900 USD

 

all you need is tune and the boost turned up rite?

 

yeah kopo has the upgraded actuator, the boost drops down to about 5 psi by redline with the stock actuator, well, let me correct myself. with the actuator adjusted the way they say to adjust it, boost drops, i now have my actuator as tight as it will go, thats what i had to do to get the boost to hold. i think i either had a bum actuator or the stock one is too weak.

 

hey tig - is there a count of folks who've had the boost drop as rpm's rise? as far as i know, everyone (including tuan) had this problem, and have used either the spun down actuator rod, or in kopo's case, upgraded actuators to keep the boost up.

has *ANYONE* reported their ST kit *NOT* drop boost (w/o the actuator adjustment or replacement)?

ahm

 

haha---APS!

nah, i dont think anybody has been lucky enough for the boost to stay strong to redline.

 

APS advertised the ST as running ~9psi all the way to redline (as you can see from the attached image, which came directly from their website).

they've now tried snowjobbing everyone who has purchased them with two different explanations. 1) exhaust back pressure is the problem, APS says. TIG takes off his entire exhaust, running with *ZERO* backpressure. result? same boost drop above 4K (obviously TIG, if I mis-speak, please correct me). so....explanation #2 comes out - 'this is a designed-in feature to help keep the motor together'. of course, the problem with that is the boost x rpm graph they pulled off their dyno (see the attachment) which clearly shows a constant boost pressure across the rpm range, and was referenced numerous times before the kits starting being sold as marketing material representative of what was being delivered to customers.

no matter how good their products may/may not be, the blatant lying, patronizing BS, and just plain arrogance of their representatives on the forums is incredible. these a33 clowns need to be evicted, and either more rational folks installed in their place, or do without. their 'contributions' are actually a negative for the community - the disinformation they are posting is confusing the issues and making it HARDER to find solutions. if only they'd just own up and admit something was wrong, and they were working on a solution, everyone i think would be a lot happier...

ahm

 

Hmmm... So what's this I hear about the APS TT hitting full boost at 3000-3200rpms? That looks like 8.5psi @ 4700rpms to me. I'm not trying to start another argument here but could someone enlighten me on the source of the graph and why it would be showing this?

 

Here's a recent boost graph from APS's own 05 model single turbo roadster with the APS TD exhaust system and custom boost map. As you can clearly see with a low back pressure exhaust system and custom boost mapping 9 psi is available from approx 2700 rpm to redline, hope this helps.

this is the ST, not TT

ahm

 

mistype. I meant ST. And no, I don't really believe anything that comes from APS dynos. I'd like to see something independent. I really have a hard time believing the above map in comparison to some other results I've seen.

 

I guess they have the date set wrong on that graph. It sais 10-8-2005.
