The video doesn’t do the car justice and it \nsounds amazing.  We are still testing with downpipe back factory exhaust. \n Clearly we are leaving power on the table without upgrading that yet and \nstill making the numbers.  Being that there is not any control currently \nfor our tuning to adjust timing, we have so much more potential in the \nfuture with this car.  Keep in mind we are on an entirely FACTORY fuel \nsystem, 93oct fuel, no meth and all boost:\u003cbr\u003eHere is a quick clip of the car doing a 40 roll on around 19psi, sounds \nAMAZING!\u003cbr\u003eBack to the details…\u003cbr\u003eAll customers looking are clearly going to be focus on power potential \nclearly with this turbo system upgrade.  Right now if you have a factory \nstock 335, you can compare our numbers simply to what you would\/can make \nwithout other supporting fuel, trans, etc mods.  We are sitting at just shy \nof 17psi right now with the car and its starting to lean out so the factory \nlow pressure pump is only going to support roughly 480rwhp.  We had to bow \nout at this point although we are more than pleased with the power and the \nlevel of boost currently running.  We hope to work with a new tuning \nsoftware company, upgrade the fueling and go back for more testing.  Our \ntarget for this car is going to be around 525-550 wheel as thats going to \nbring us to the limit of the factory transmission(automatic).  This is also \nan important point as we would be making slightly more power with a manual \ntransmission car so we are eating up a little power for those strictly \ninterested in power numbers.\u003cbr\u003eIntercooler Technical DATA:\u003cbr\u003eWe initially base lined our test car with the factory intercooler at ~17psi \nof boost.  Since then, we upgraded the car to our new 7″ Core 335i \nIntercooler and went back to the dyno for a few more pulls.  Not surprised, \nthe IAT’s were down and from the start of the pull till the end, we are \nonly getting about a 10 degree rise.  The pull was starting at ~100 degrees \nF and ends right at 110 degrees F.  This is a HUGE gain and by simply \nkeeping the temps cool going into the engine.   We were down 1psi at 16# of \nboost and making 40 MORE HP to the tires at 6100rpm.  So if you are pushing \nthe stock turbos or on an upgraded turbo setup, this is a must have.  We \ndo sell the intercooler upgrade by itself so check out the BMW section for \nthat specific upgrade if you are interested.  Serious power potential and \nkeeps the IAT’s in check.  This is included with your turbo system purchase \nso your going to have the most efficient setup and coolest air charge temps \npossible  \u003cbr\u003eKeep in mind with this car, its a completely stock 335i we started with, \nthere is zero upgrades and it is an AUTOMATIC transmission so our numbers \nwill be a little lower than a manual car(still making killer power).  We \nare running out of fuel so the stock low pressure pump needs upgraded if \nmaking anymore power than this.  We are more than satisfied with the system \nand easily going to crack 500rwhp after the pump upgrade.  That is the only \nthing holding us back right now and this is on pump 93 oct fuel, 7 degrees \ntotal timing!\u003cbr\u003eWant to see the prototype car run, photos, and anything new?
