seen a plug & play box for just £140, for a jaguar s type 2.7d
it gives it around 25% more power (which will become 255BHP)
will this improve the acceleration?
yes probably by a quarter of a second. but its not enough. what i would do is apply :
1. a twin turbo kit with twin intercoolers
2 swapping my transmission for a high performance one (quickshift)
3 weight reduction
4 pod filter
5 enlarged exhaust
6 supercharger (believe it or not, you can put a turbo and supercharger of one engine at the same time. but fuel costs will bite)
