I think it's 8 and 13 for their stage 2 kits. I have 16 and 23 for their stage 2.5 kit.

I have a DYNO* of those boost levels that is.

I'll step in here quick. I just had my M3 shipped to New Jersey for the boys at Maximum PSI to work their magic on. Luke has been a pleasure to work with and I am excited to see the outcome! My car is an SMG, so they will likely keep it for a month or two to make sure everything works as desired.

I have my own dyno to do some personal testing, and I have no doubts the kit will not disappoint. I'll post up in here with some dyno sheets and driving impressions once I get the car back. I work in diesel performance, so I am no stranger to horsepower!

Thanks Maximum PSI!

I am excited to get your car in!! It should be a rather quick turn around on the build. We are just waiting on the clutch and the bushings to show up, then is on!

MaxPSI - Is your kit compatible with RHD M3's?

No, the current hardware will need to be changed. Please contact us if you would be interested in shipping a car over to fabricate the rhd components.

Thanks Mike. I'm not in a position at this stage but will watch any RHD developments with interest. The HPF RHD kit has certainly generated much interest.

So Mike, how feasible would it be to get a wrecked M3, swap in a RHD steering column, rack, and brake booster, and modify the kit for RHD cars?

doesn't HPF run the steering column right in between each manifold (one bottom mount, one top)?

Nick, while you're in this thread, i asked this a while back and never got an answer. what programming, if any, is in place as a failsafe? is there anything in the DME that would do something, if say, a sharp boost spike occured?

Normally, there are airflow limits in the DME. Airflow = boost. Flow too much air (ie, too much boost) and you'll set a fault and put the DME into limp mode. This kit was designed to operate safely on 8.5psi of boost with 93 octane fuel. BUT, we also wanted the kit to put out more power if higher octane fuel was used (ie, the 600+rwhp with 100 octane and 13psi that was reported in another thread).

And herein lies the problem, with a decision to be made......

In order for the DME to support high octane with 13psi boost, means it can't detect whether the boost you're running is 'normal' or 'abnormal'. If you've filled up with 100 octane, then 13psi is 'normal'. If you're on 93 octane and your boost controller fails and you hit 13psi, that is 'abnormal'. The DME can't distinguish between those two scenarios.

So since the majority of customers want to turbo their S54 because they want POWER, we decided to relax these airflow checks and allow the DME software to support the high octane/high boost condition without needing a reflash......just fill up/turn it up and go!

The DME will still detect a failed mass air meter, but it won't throw a fault for an overboost condition, since it really can't tell if that overboost was intentional or not.

Could overboost only be permitted if certain controls are activated? Like pressing the M button? I suppose that would depend on the DME being able to detect the control. Comments?

You can use an electronic boost controller like an Eboost 2. If there is an overboost situation it will default to wg spring pressure.

We already have plans for the 'Sport' button
