@ what rpm was that?
Thats amazing!!!

 

prolly like 5k ish

 

Have you had the ECU before getting a downpipe?

 

nope, the full turbo back exhaust was my first mod.

 

That Really is crazy! That's a lot psi's!

 

your talking your ecu is remaped to push 21? because the stock s ecu is mapped to push 14.5

 

My Sig-O-Matic shows my set up. Here's the video:

Dont think ive heard of anyone getting 14.5 psi on a stock map..

Standard peak boost levels are 9/10 psi with an overboost of 12 psi

 

lucky me i guess i get 14.5 but i want 21

 

id be suspicious of that reading boost spike perhaps... But 21 psi is the way to go.

 

I have a march 07' build, and I hit 15.5psi all day long with a stock map. I believe Adam w/Alta said something about the early build r56's giving up additional boost when an exhaust is added. Later builds are a bit more stingy.

 

I didnt know we were bringing exhausts into the equation.. Ive watched my psi levels increase with certain choice mods but again ive never seen a 4 psi increase with just an exhaust (on the standard map).. And later minis being more stingy ? Again the book figures are the same for late 2006 cooper s's as they are for late 2008's (well here in europe atleast) and i cant see mini offering up 9-10psi of boost (peak hold) with an overboost of 12psi to some customers and 15 to others

Of course you can have 15+psi with loads of bolt ons and a standard map but my point was most definetly you dont get 15 psi off a standard map on a standard car..

 

That's a short lived motor and turbo for sure!

 

Temperatures were around 50 degrees F. on Sunday and the MINI peaked boost at 14.9 PSIg. This is the first time I have recorded a peak that high.

 

Colder weather certainly helps. I have just realised the most incredibly obvious thing ever that my boost gauage doesnt centre at 0. It is about -0.75 (3/4 of the way between 0 an 1) when the engine is OFF. So I am adding 0.75psi to whatever boost I get.. The most I got the other night temperature was -1 celcius I spiked at 18.75psi and then held 18psi all the way to about 6000rpm, then it reduced to about 16/17.
