Bad Apples Donating Members 110 Member For: 19y 7m 17d Gender: Male Posted 07/03/11 11:48 AM Share Posted 07/03/11 11:48 AM Hi All.I currently run BA camshafts in a 698 atomic engine.I'd like to ask people experiences with the larger camshafts for a daily driver, taking into account idle torque (for taking off discreetly at 6:30 am), and fuel economy.I expect the BF cams give a significant improvement in power (based on the specs, and tuning results), but good economy (given they are factory fitted).What about the next size up? -I.e. atomic stage 3 and Crowcams #3231393?Then there are crowcams 3232562, which is larger, but aimed at NA, so may aid off boost performance...The next size up is atomic stage 4. Do they produce usable torque near idle?There is an opportunity to fit larger camshafts in the near future, but retain standard exhaust manifold and turbo. The exhaust is CES 3.5" turbo back. The intake is process west race airbox. nizpro 'original' intercooler and process west throttle body re-location.Only 1 round of (engine) upgrades to go, .. GTX 4294 (1.01 turbine A/R) on a 6boost style manifold - so bear in mind I'd like the final configuration to suit, as a daily driver. Other relavent information is that being a BA I have the BA ecu, I do not expect this to be a limitation but I understand the newer ones are better...Please share your experiences Cheers,Chris.

U don't get that much gain with these motors with boost and big cams. The outlay and extra fuel consumption isn't worth the small gain. Link to comment Share on other sites More sharing options...

I have tried to look some say yes some say no? Link to comment Share on other sites More sharing options...

And I'm not sure if Lobe separation can be adjusted in the tune between NA and Turbo Link to comment Share on other sites More sharing options...
