I am getting my car next week from the shop (getting the Vortech SC installed).

I am planning to upgrade the pulley to a 9 psi one and the injectors to RC650's. Just got a rod knock so I had to replace the engine so I won't be able to afford an AEM EMS so I am planning to use eManage.

If I add these parts and get the eManage tuned, how much more horsepower should I expect over the stock Vortech Kit??? I have never been in a SC'ed S2K so I have no idea how fast it will get. Do you guys think I will be seeing a lot more difference by putting the eManage, injectors, and the 9 psi pulley???Sorry if it was asked before, please send me the link if it was...

 

The eManage will not support 650 injectors. I tried the same combo and the engine will fall on its face at vtech I had to limp the car home from the dyno and wait 10days for my EMS to show up. stick witht the stock vortech setup until you can afford EMS. The greddy just can't handle that much modification.

The emanage uses compensation over factory injectors to allow you to alter size. 550 injectors are the upper bounds of it compensation abilities.

my 9psi pulley and ems and the rest in my sig got me 325rwhp. really humid rainy day I am going back soon for a touch up and base line run. I hope to see 330+

 

Yeah, emanage is fine up to 550cc, but you could probably use 550s with 9psi. I would go with AEM. I made the mistake of emanage first and now that I am upgrading I wish I would have just done it all right the first time. Plus, when you want to get higher than 9psi, you will already be set with EMS.

 

I am not planning to go more than 9 psi. in fact, i am not planning to upgrade the pulley and injectors if it will not add much. can you really feel the difference over then stock Vortech Kit?? BTW, if I get 550cc injectors and 9 psi pulley, would I be fine with eManage???

 

I havent tried 550 and 9psi with emanage, but my tuner said that is the max setup emanage will handle. I dont know how safe it would be running at max for any computer. You might get an additional 20-30hp over stock vortech with that setup, so you also have to weigh if that is worth it.
