shows no power dont low..not very streatable power... guess thats what u like...
I want to definitively make this point about "no power dont low..not very streatable power" that you are mentioning clear for everyone, I also don't want a misinformation starting around because I am not reporting.
I'm using my free time since some days (nights) to optimized the tune on the car with my usual HPTuners software.
- The engine is idling now a solid 900 rpm with only +/- 40rpm from cold to full temp or any kind of restart.
- Streetability is back to stock...YES back to smoothness used to in a ZO6, stock leaving a stop, stock in stop and go traffic, and I can cruise for ever 6th gear at 1200 rpm, stock except for emissions and the fuel smell !!!
- Power wise PLEASE take a look at the compare below, that's my engine before and after my last combo. Between 3000 rpm and 4000 rpm the engine was already a lot stronger vs. stock on the before curve.
- Steetability zone is PARTIAL THROTTLE and between 1000 rpm and 2800 rpm and will never show on a dyno sheet.
An update from today for some of you that are asking about my future time at the drag strip.
As I am not going to race the car immediately here is the following:
As some members are asking me through PM questions on the shape of the power and torque curve of my engine, I am posting below an overlay from the day where I left the car to J&J (11/17/06) and the day where I had my car back (12/27/06).
The general consensus was that there was a probability to lose power down low, in the 3000 rpm to 4000 rpm range...and I was convinced that going to a bigger camshaft and increasing the overlap could only lead to that.
I was lucky with my combo, NO LOSS down low, matching in the zone and some little plus in term of power on the dyno.
The accelerations time are EXACTLY the same on the road between 3000 rpm and 4000 rpm !!! (always monitered the same way of my usual process that most of you are aware of through HP Tuner)
The gain in power are after 4200 rpm but the HUGE GAIN in accelerations is between 4600 rpm and 7100 rpm, ~2 seconds on ~11 seconds....
EXACT ACCELERATION TIME 4 GEAR 100 mph to 153 mph 4600 rpm/7000 rpm:
May be those acceleration numbers are telling something to the specialist here around.
That is the process used by all the newspapers and racing journalist in Europe to compare the power car to car, no traction or grip parameters induce in the game.
