russian rocket Posted February 4, 2017 Report Share Posted February 4, 2017 Im really happy with the numbers it put down and surprised with how much of a difference disconnecting the bypass valve makes 2011 sedan auto Pump 93 Dyno jet Outside temp 23 degrees only mods: Air raid intake Exhaust cut outs just before the mufflers stock untuned ecu *actual 1st run not shown because it was a shake down run at 50% throttle* 1st run off the street, no cool down 483whp and 462wtq 2nd run no cool down, bypass solenoid adjusted so that it wasn't touching the valve 476whp and 466wtq 3rd run no cool down cut outs open 484whp and 453wtq 4th run no cool down bypass solenoid unplugged 490whp and 461wtq Final run let the car cool down for 20 min with a big fan on it drawing in cold outside air 516whp and 483wtq last pic shows a comparison between my first and last runs, you can clearly see where the car is either pulling timing or is actuating the bypass valve For comparison, my brother in law has a 2010 camaro ss 6 speed it has: 2in LT headers, cats deleted BTR stg4 cam CAI Exhaust cut outs right at the end of the headers and tuned his car made 474whp on the same dyno Quote Link to comment Share on other sites More sharing options...
TTQ B4U Posted February 4, 2017 Report Share Posted February 4, 2017 Nice! bypass solenoid.......is that bleeding off boost? I know on my car unless it's tuned it will bleed off the extra boost. Quote Link to comment Share on other sites More sharing options...
Nickey4271647545519 Posted February 4, 2017 Report Share Posted February 4, 2017 Well that's a dyno cell I haven't seen in a minute. I'm impressed with those numbers from a fairly stock car. Quote Link to comment Share on other sites More sharing options...
russian rocket Posted February 4, 2017 Author Report Share Posted February 4, 2017 Nice! bypass solenoid.......is that bleeding off boost? I know on my car unless it's tuned it will bleed off the extra boost. i believe so but i am not 100% sure on that. i know if the bypass isnt closing all the way, it will bleed off some boost, thats why i adjusted it so that the set screw was not touching the butterfly valve. then on the final 2 runs, i unplugged the vacuum source to the bypass valve and that seems to have made a huge difference. so that kind of tells me that the ecu probably does bleed of extra boost over a set amount.

DKilbourne Posted February 5, 2017 Report Share Posted February 5, 2017 Get a nice trunk mounted intercooler tank to ice the shit out of it for track visits. That will really help keep those charge temps down. Quote Link to comment Share on other sites More sharing options...

That will really help keep those charge temps down. iv been looking at the engine bay mounted ones, i like how clean they look and its a much shorter distance. though they do have their downsides Quote Link to comment Share on other sites More sharing options...

Oh, and where the hell is the e85? Quote Link to comment Share on other sites More sharing options...

Oh, and where the hell is the e85? yep lol, thats the biggest draw back, but i dont see that being much of an issue, for the most part the only time i will be topping it off with ice would be right before a race. e85 is definitely in the plans, there is a cool flex fuel kit that will seamlessly transition between e85 and pump 93, but i will obviously need a tune and bigger injectors to go along with it Quote Link to comment Share on other sites More sharing options...
