Milltek will be on very soon, cooling is a problem due to space and lack of viable options which are proven. Aint sure how much more bhp is available from the e05 once Milltek, cooling, is sorted or/if bigger injectors would be required at this point. I think the milltek will ntake me to the 240-245bhp mark, not sure what i will gain say from a chargecooler.
I think once cooling is sorted and sports cat and dp is on boost can be raised to 21psi, but i have no idea how much more bhp and torque it would make.
Ok, I've done a bit of maths on this :
Assumptions :
1.8T flows 170CFM @ 6000RPM
22psi peak boost = 14psi @ peak power - extrapolated from RR plot where it seems you get ~10psi with 18psi peak.
Ambient Temp = 15 Degs C.
Negligible Pressure drop across IC/CC/inlet tract.
Compressor Efficiency of 70%
So, with no IC at all you'd get 100.69 Degs C intake temp giving ~212bhp.
With a 60% efficient IC/CC you'd get intake temp of 50 Degs C giving ~245 bhp.
With a 70% efficient IC/CC you'd get intake temp of 40.5 Degs C giving ~252bhp.
So your questions for Pace are :
1. What is the P-drop across the CC with a flow rate of ~300CFM?
2. What is the efficiency of the CC or T-out for a given T-in at a given ambient?
IMO, ~£850 is strong money but if you can't make your own...
