There is only so much reading one will do before losing attention, here is a few video clips from us strapping the car down and testing throughly testing this turbo system. The video doesn’t do the car justice and it sounds amazing. We are still testing with downpipe back factory exhaust. Clearly we are leaving power on the table without upgrading that yet and still making the numbers. Being that there is not any control currently for our tuning to adjust timing, we have so much more potential in the future with this car. Keep in mind we are on an entirely FACTORY fuel system, 93oct fuel, no meth and all boost:
Here is a quick clip of the car doing a 40 roll on around 19psi, sounds AMAZING!
Back to the details…
Dyno / Boost Details
All customers looking are clearly going to be focus on power potential clearly with this turbo system upgrade. Right now if you have a factory stock 335, you can compare our numbers simply to what you would/can make without other supporting fuel, trans, etc mods. We are sitting at just shy of 17psi right now with the car and its starting to lean out so the factory low pressure pump is only going to support roughly 480rwhp. We had to bow out at this point although we are more than pleased with the power and the level of boost currently running. We hope to work with a new tuning software company, upgrade the fueling and go back for more testing. Our target for this car is going to be around 525-550 wheel as thats going to bring us to the limit of the factory transmission(automatic). This is also an important point as we would be making slightly more power with a manual transmission car so we are eating up a little power for those strictly interested in power numbers.
Intercooler Technical DATA:
We initially base lined our test car with the factory intercooler at ~17psi of boost. Since then, we upgraded the car to our new 7″ Core 335i Intercooler and went back to the dyno for a few more pulls. Not surprised, the IAT’s were down and from the start of the pull till the end, we are only getting about a 10 degree rise. The pull was starting at ~100 degrees F and ends right at 110 degrees F. This is a HUGE gain and by simply keeping the temps cool going into the engine. We were down 1psi at 16# of boost and making 40 MORE HP to the tires at 6100rpm. So if you are pushing the stock turbos or on an upgraded turbo setup, this is a must have. We do sell the intercooler upgrade by itself so check out the BMW section for that specific upgrade if you are interested. Serious power potential and keeps the IAT’s in check. This is included with your turbo system purchase so your going to have the most efficient setup and coolest air charge temps possible
Keep in mind with this car, its a completely stock 335i we started with, there is zero upgrades and it is an AUTOMATIC transmission so our numbers will be a little lower than a manual car(still making killer power). We are running out of fuel so the stock low pressure pump needs upgraded if making anymore power than this. We are more than satisfied with the system and easily going to crack 500rwhp after the pump upgrade. That is the only thing holding us back right now and this is on pump 93 oct fuel, 7 degrees total timing!

Coolant Overflow Tank Relocation Info: We get calls on the coolant tank and what needs to be done very often. It cannot stay in the factory location as it interferes with the tubing and the way we have it routed. It simply is relocated to the firewall, if you need photos, please let us know and we can send you exactly how we have ours mounted. It doesn’t require any brackets or anything special, you can simply drill a few holes and bolt it right to the firewall on the Driver side. We then run a new coolant hose to make the connection for the extended area and your good to go!
