Separate names with a comma.
Supercharger output duct and intercooler output duct ported at Endyn.
Yes, you have the right idea, a balanced systems approach. Matching the intake manifold to the head pays dividends when the head or IM has core...
Here’s the precision machining involved in the new generation of MINI headwork from Endyn. http://www.werkinmini.com/ENDYN%20headwork.pdf
The head deck of a mid-size valve head.
Note each port is precisely equal.
The head photos shown bellow are of mdbsat's custom mid-size valve head. Unfortunately a recent dyno didn’t fit into his schedule; I’m sure he...
And here it comes! The latest CNC & hand blending headwork for the MINI from Endyn; smooth air pathway past the mid-size valve seats both coming...
Free flowing air path past the valve seat, both coming and going.
New CNC headwork for the MINI from Endyn. Amazing direct path for the intake charge and uniformity for each cylinder.
The latest CNC mid-size valve headwork for the MINI, optimized for use with the NS1 camshaft; shown is the exhaust port.
I've owned Alta pulleys in both 15% and 19% reductions with only the logo, no % designation.
Inadequate lubrication caused the cam journal to seize; it was discovered the oil pump gears were cracked and a section of gear missing.
Back pressure can be reduced by removing the OEM header's pre-cat.
The OEM header flange ports can be enlarged to match exhaust ports on a ported head.
The interior diameter of the tubing exit at the flange after the cat can be increased be grinding the interior weld bead.
The oil pump is located on the end of the crankshaft behind the cam chain cover.
The Cooper crank pulley has an elastomer O-ring sandwiched within.
I’m going to take a guess Alta responded to loose PSRS sleeves in the V1 by under-boring the V2 sleeve so the user must press the sleeve on the...
