Race? Only on the drag/strip track.. yes sure, after I complete working on it..
I had a terrible cam & blower combo.. my bad.. I was a rookie 2 years ago, when I decided to replace my excellent & powerful N/A combo with non-compatible coctail of high performance parts.
You see with the wide overlap degrees of that E303 cam whcih I had (110) plus the long durations, the pressurized flow from the compressor was scavenging the air/fuel mixture out through the off-road exhaust system.. causing high vacuum, loss of combustion energy, loss of torque & power, hell of a backfire. In another words, it was much more powerful with the right N/A combo.
In addition, the MAF sensor was not calibrated to the new injectors, and the stock ECU was not tuned. That was when I was naive - but people learn from their mistakes
Anyway... I have more theoritical & practical knowledge now, I've done my homework and I'm on it. Personally.
