Taffy

Have you ever done this same build up and tested it on the same exact dyno to get readings? I have. I am not sure if you read my first post correctly or not, but I said that it was at 10 psig up to about 6K, then all the way to 7500, it fell to 8 psig. At 8 PSIG at 7500, it made 310rwhp, which is 235rwkw.

This was on my car. All dyno tests were done on the same dyno as well. 50rwkw is hard to believe, but the dyno does not lie. The increase was using the Greddy Intake and a 4" core FMIC. Before, it had the stock RB25 side mount and stock intake manifold. It would have made more power, but the turbo was out of steam. It held 10 psig all the way to about 6K, but then fell to 8 psig all the way to 7500. I am not advertising the AEM EMS, in fact, I would rather no one buy one. Their quality assurance program is non-existant, and they customer support is useless when it comes to any real questions.

RB25DET Series II Stock set up with APEXi Filter and "replacement" 2.5" exhaust I made 220 RWHP (164 RWKW). With the addition of the AEM EMS, I made 245 RWHP (183 RWKW). Dyno Graph Below. Both runs were at the stock 8 psig boost level. I then added an APEXi N1 Cat Back, and a 3" stright thru cat delete, 4" intercooler, and a Greddy Intake Manifold. The results are 310 RWHP (231 RWKW) at the same 8 psig. We tried to up the boost, but it would only go to 10 psig at 6200, then it bled back to 8 psig by 7K. The turbo is pretty much done. On this dyno pull, I made 250 RWTQ (34.6 KG-M) from 3000 to redline.

If anyone is having problems with their AEM EMS not syncing up properly, please let me know.

Is anyone using the AEM EMS on their RB powered cars? We have been having a few problems, and I just want to see if anyone else is having the same problems. My application is an R33 GTS25T Series II. The car is an S13.

I am looking for a set of RB25DET Series II cams. Preferrably 264 duration. Thanks!
