3,48 PSI, between SL55 Y-pipe and green filter, in my car ) Inside 3´
Cooling system separated. Johnson 30 pump.
LET 185 mm pulley, Feritta Race system, with two - 100 cells cats.
World biggest HE. Bigger than Needswing new Super HE.Cooling down in 10 sek, when you let of the trottel. Back to crousing temp.
First day at tuning both hit MAP sensor limit. Day three everything was fixt
by a German fellow, T.M. Chiptuning. Dont know how he fixt all problem.
No limp mode or nothing. Intake pressure 21 - 22 psi. Before we hit the MAP sensor limit all day.
Now the car is running as he...
We tried to Dyno Lars car but there was to mutch slip on the tires.
The only thing we checked was the AFR. And there where no problem.
11,7 AFR. My car is between 11,6 - 11,7 - 6400 rpm. RPM Limit is from Kleemann.
Next run is in May. With Needswings intake manifold and VRP Headers.
And Hoosier tires. Interesting.
By the way. My car is faster than he's
This is going to be big fun.

Thanks.
And separation the two cooling system.
This was one problem to fix, and after this big HE i did not see any problem.
The Intercooer is to small with big pressure and there is nothing to do.
We just have to live with that small Intercooler.
For me its not a problem. I can still run all Street race. And the car is not to hot. Yet. Cooling down in sek.
Before, i checked IAT, air temp and everything. Let the turbo car wait a 30 sek , and then you WOT. Today, i dont care. Everything is working.
The different is outstanding. This is what our cars need. A big HE.
I will check the temp.
I have tested the car with BIG HE two years. This is the way to go.
