hi i have modified my 93 325 and i am not happy with results. last year i bought the car in may and it had only a remus exaust.ihad also done a compression test and got 210-200 through all the cylinders. i bought a turner chip and tried it at the drag strip my best run was 15.33 at 89mph and 2.25 60foot.
a week later i lent my car to my brother and he $shift my car. i wanted to kill him but shit happens. my mecanik open the engine and found all the exaust valves bent they had hit the pistons.it was repairable so he changed all my valves cleaned and machined the head put a new head gasket and put it together.this year i put in 3.23 lsd, fan delete,ecis cold air intake, and m3 cams with turner chip.i took it to the drag strip last week and my best run was 15.22 93mph and 2.35 60 foot.i friend of mine was with me with his 99 328i with some small mods like pullys, oils, and his best run was 15.09 at 94 mph. i was pretty disapointed so i went home and did a compression test and found 170-180 through all the cylinders.by the way my engine is running healthy and feels stronger than ever i also have been doing very frequent oil changes because i had noticed alot of sluge build up in the engine when i bought it, now it is much much cleaner.so what is up with this shouldn't i have more power with all this mods. what could be wrong. shouldn't i have a little higher compression after machining the head. please some expert feedback.
