Just did my first log last night. I do not have a boost gauge or a wideband in the car as of yet. Running a Roe and just got the car running and been driving it pretty easy for the last couple weekends. Decided to do a log with the car to see how the tuning works. I'm running a 8lbs pulley with the david weaver pulley and from what the vec internal map says, I'm only pushing 6.18lbs at the highest. Does this sound right??? The car pulls hard and smooth. I know it isn't much help without any A/F ratio's and I don't have a boost gauge to verify. Just wanted to know if this is normal. From what I've read, the larger crank pulley causes an increase in boost, so I was guessing I should have around 10-11psi.
How accurate is the horsepower calculator. I have not yet been to a dyno but it says i'm at 744 horsepower. I don't think this is correct. Although the car does feel like my chest is going to cave-in when floored it, so just curious of the accuracy.
Another factor that is that I'm at Albuqerque, NM and our elevation is around 5,000 feet, not sure if that has anything with the boost level.
Attached is my log. This was done in 2nd gear.
Could someone take a look at it and tell me if they see anything wrong?
Here's my list of mods:
Bored .022 over
