Hello to all,
I am new here, first post.
I have recently acquired an AC Cobra (replica), it has done a total of 600 miles on the chassis, the only parts with more on them are the engine and gearbox which have been reconditioned.
The engine is a 3.5L from a 535i (89/90) model year and was believed to have covered approx. 40K before being taken out and recon'd. The Cobra is a fairly light weight car coming in at just over the tonne but despite this I don't feel it has enough go, the throttle response feels lethargic and nothing seems to happen much below 3000rpm then things start to come alive but to me it just does not have that sharpness of response.
Don't get me wrong the car is a dream to drive, handles well, has fully adjustable suspension all round and I can sit in relative comfort and although I bemoan the lack of response below 3000rpm it does have it's plus points in that it is very docile for driving in traffic or around town.
The only performance related items it has are the addition of the two side exit exhaust and a Piper cross cone filter, the rest is standard. I am not sure if the ECU has been remapped to account for the exhaust and filter so they could actually be working against the engine as is. From what I can see the engine should be rated at around 211 bhp but my question is what can I do to liven things up but still keep it useable?
Hope this makes sense and I get some real help and advice.
Thanks in advance........ A few pictures.....
