hi got my self a ef2 xr8 manual , looking at making some more mod,s. so i started with a dyno to see where i am. first dyno made 176.5rwhp.



after that i fitted some m&h headers with sport exhaust , replaced the air flow meter as it was in the low 10.1 ratio which is to low making it run to rich and replace spark plugs , fuel filter , drilled hole at the bottem of the air box , and re-set the timing. went back for a dyno.





now like to made some more mod's but not sure where to go next. if you have any ideas or know how please help. here's some photo's off my car.

That's some pretty sweet power output there!

Up next i would HIGHLY recommend getting some underdrive pulleys, you will notice a big difference.

You can get them for about $205 delivered, but you will have to get a new bolt pattern drilled to suit the water pump. If you get Blue Oval Industries' pulleys the alternator pulley fits straight on with no mod.

Get an explorer (AU XR8) intake manifold set and throttle body.

yes was looking at under drive pulleys and was also thinking of a 75mm air flow meter as well. will like to know more about the ecu and what chip would be best. with upper and lower manafold was going to port them out a bit frist and then go form there.
