Hello.. I noticed that there is another post explaining the origin of this engine in Brazil, so I will not extend myself. The engine of this car here has been inherited from Opala 4100 and some changes made by Lotus in the 90 years.
The car is equipped with 4100 engine (250CID) and the compression ratio is 8.5. At this point it has peak of 16psi boost. The clutch system is showing a failure to adhere. Soon I will replace it with a stronger model with ceramic inserts. The TBM transmission will undergo modifications and have more resistant forged gears.
Anyway, I will now forward some information from the engines manufactured here to the Omega platform (which for you is the Senator or Carlton)

As for the intercooler, I am not using, but I am monitoring the air temperature in the intake manifold (after the turbine). With 18psi, the temperature reaches 90C which is about 195F. I know that an intercooler could improve the yield of the set and avoid breaks but the aluminum manufactured around here has high cost, and at the moment I have no money.. $$$$$$$$$$$
Gradually the car will receive the improvements and how soon I will post the modifications if it is of interest to the forum.
Thank you all
