The Impact of Methanol Injection
View attachment 77734
Final mapping is now completed. The impact the methanol injection has had is clear to see. It has allowed the map to be adjusted significantly, resulting in more torque & power throughout most of the Rev range, but not higher up as this was restricted to protect the engine / gearbox, but it's clear to see what the pub figures could be.
Importantly the meth has allowed for a much better map without increasing the boost levels which are still sat an incredible 16psi (1.1bar). The data logs for the car show all parameters to be very good indeed, so no limits being pushed.
So in summary, the turbos are not being worked too hard, because of this the heat being generated internally within the engine is not at all high. The meth is adding massive value - so from where we were previously we have more power and torque through the rev range, with the same boost and safer, smoother map!
The power and torque curve shapes have been kept the same as previously, this is purely to assist delivery of the power through the rear wheels. With the latest map there is circa 60-100/ft of torque extra at most points below 5k and it’s noticeable, especially when accelerating hard from low speed. However, it is much better than having 800-900lb/ft at 2500rpm as the wheels would just spin and it would eventually kill the gearbox. For me the above type of map for power delivery is key to make use of it on the road. Headline numbers are 912bhp and 970lb/ft........
Big thanks to Acid and the team at MSL Performance, Imran at Torqueflow, John at Big Fish Tuning and Cooling Mist.
Now off to VMax200 to see what it will do.......
