Turbocharged Headers Equipped SMART car.. a Vicious Screamin' Cow

[LittoDeviL]

forestacademy, I wont ship the car, if I'm going to I'll drive the car there

babybenz, no calculation shows that the amount of gas that is coming out of the smart engine doesn't require me to have an external wastegate as the internal ported wastegate controls my boost just fine, I have no boost creep or anything. Since your turbo is sized smaller then optimal you'll have benefit in having the external wastegate but not me hehe, I wouldn't benefit from having an external wastegate, however I do have a blow off valve but that's irrelevant haha.

NICE PROJECT

Thanks, as Gearhead, a friend of mines mention to me and as I kind of figured out... due to the shape of the intake manifold the alcohol, water/methane injection to cool the intake charge down would just puddle on the bottom of the intake manifold. Having to inject it right before the intake valve would require me to drill and tap the manifold which would be a permanent installation.

The next best thing is to cryogenically freeze the intake charge using CO2 like this product:



This way even though I can't increase boost I'll still get more power due to a much denser air. Keep in mind my CURRENT intake air temp is NO MORE then 109 degrees at FULL boost and full throttle... full load... which is VERY cool meaning my water to air intercooler barrel is doing a fantastic job at taking out the heat generated from the turbo and engine.

Good question, but no it wouldn't help on a naturally aspirated smart, the injectors used are more then enough for the regular smart car, no matter how cold the air gets going into the engine (cool air is more dense.. more air means more fuel is required to achieve the proper 14.7 to 1 air to fuel ratio).
