APS ST Impressions
Hey guys...I have had my car for a little over a day now and thought I'd give you my thoughts on the APS single turbo. As far as specs go....the car was tuned by Tuan for 9 psi and is making 378 rwhp and 400 lb/ft torque.
Let me be the first to say the APS ST kit is simply fantastic. This is honestly the way I imagined a sports car to be. I don't think Ill ever buy another non-turbo sports car. Im boosting the full 9 psi right around 3200 rpm or somewhere around there. The install seems to have gone flawless. I pretty much beat the living hell out of the car all of last night and today and I just checked all the fluids and there aren't any leaks and the oil is still topped off. GRD will be checking the car out tomorrow to see if everything is holding up well and there aren't any leaks...but everything looks ok with so far.
GRD had the y-pipe fabricated for my Greddy EVO2 and man the car sounds really mean now. It did not mute it one bit.
I also want to mention that I am on my stock clutch and there isnt any slipping whatsoever. I am very happy I didnt dish out the extra cash yet. I will be sure to put this one to full use.
I do have one complaint though....when starting the car it doesn't start up as easy as it used to..I have to hold the ignition a little longer than normal. I thought that was strange and after filling up today the car didn't start on initial attempt. The second attempt was successful but once again it took extra effort in holding the ignition....Im just not really comfortable with that. Also after it started...it now seems to be idling really low around 500 rpm. It kinda sounds like its about to die but it doesn't. Just don't feel comfortable with that. Anyways hopefully that will all be figured out tomorrow. They are minor problems so Im not really worried about it.
Good luck to all you guys with the ST... you will love it...the car just flies in every gear.....0-60 must be about 4 sec with 100 approaching a few seconds later. The sound of the car is also just flat out amazing. I honeslty coudn't be happier with my decision...
Many thanks to Tuan, Irshad, GRD crew, and Peter of course for everything. GRD is an excellent shop to deal with and I hope to do much more business with them again next year when Im in town again.

I would say check the oil return.
I tested the Brainstorm ST ZR and I was just going to take a few hot runs but I ended up cruising the beach for 45 minutes lol. Didn't even know it was there until 4k rpm and you hear the spinning fans. Only thing that can top that experience is 2 snails.

Most FI cars are hard to start right after installation for a week or two.

Double check your connections. If it is not that try priming the fuel system by switching the key to "on" before cranking the car.
I see many posts after FI install that say the car is harder to start and idles funny for about a week until the computer adjusts...

actually I did.. I always thought the Turbonetics kit hitting full boost in your car so soon even with all the piping was very impressive. But you also need to take into account the trim of the turbos. I'm sure this has been discussed many times elsewhere so I hope I am not opening another can of worms.
APS' shorter piping with less bends should clearly help spool up quite a bit more than the turbonetics, but then you can't see the turbo like Turbonetics so that's the drawback, or not, depending on what you want. I personally think Turbonetics' turbo sizing is perfect for the piping they have, and APS' is perfect for theirs from what I see.
Looking forward to hear more about the dyno.. Is this 400 wtq on a Dynojet? What does this kit put out before the tuning with the APS map? I'll be patient to hear more about it.

I'd like to maybe bump mine to 9 PSI soon and do an overlay of the curves since I'm making 380 at 8 PSI.
