The problem is its a N/A engine and whats the general rule 100bhp/litre or thereabouts. To get 240 will do me. If Spikes exhaust produces an 8bhp increase then the difference in the ph1/2 vees is the expected 25bhp. To have 80% of the 100bhp/litre rule is great considering that includes a durable long lasting reliable engine.
Also consider the L7X engine was in a Laguna. Upgraded for the ph1 then once again by porsche for the ph2. To go further well .......... one lesson learned is consider all money spent as non-recoverable before you start and .....well..... good luck!!
It was interesting to see people's reactions to the figures on the screens!! Generally not quite achieving the figures they expected.... nothing new there then!! Except for John's Mustang what a beast!! I have to say the only time my vee has been totally outgunned on the road was against a Lamborghini Murcielago and an F430 otherwise its plenty quick
Does anyone know of or owned any N/A cars and have achieved significant gains??????? If so how was it achieved?
