So, we finally have the rebuilt engine back in the car and we decided to tune it on a "rolling road" to make sure we got the mixture right.
So this is a 75 2.0 with standard FI and no emmissions gear on it. I had sort of hoped for around 75hp at the wheels but it has come out at 57hp rwhp. Engine has new AA pistons and cylinders and the standard 2.0 heads so does this sort of number sound right and if it's way short what could be the problem. Also, will it get better as the new pistons settle in. I go get the car on Friday so will put some pics up then |

Look at picture of my stock 2.0L on a rolling dyno-91hp at the rear wheels. It was a total rebuild but with flat top pistons at 8 to 1 CR.
I had tuned the MPS and it looks totally correct if you look at the AFR 13.5 to 1. 55 RWHP is weak..... (IMG:style_emoticons/default/chair.gif) |
