To clarify, I was talking about a stock 16v largeport bluetop engine. It comes with 115hp 100ft/lbs stock... which minus 17% drivetrain loss would equate to 95rwhp 83ft/lbs. To claim a 40hp & 20 ft/lbs gain to 135rwhp 103ft/lbs by just a standalone and cams (no intake manifold, no ITBs, no porting, and keeping all emissions equipment) is far fetched on a 1.6L Naturally Aspirated engine. Thats all I was saying.
Not a smallport, not a custom intake manifold or ITB'ed engine or full out race engine with no emissions equipment, not a Holden V8........ a stock bluetop 4A-GE. Yes, 40/20 gain is working magic.

Camshafts have been chosen!
226 degree @ .050" lift
lift to be 8.38mm
centers @112 degrees
Information is POWER... learn the facts!!
whats that translate to in jap "bigger" duration?
264 type... cam timing is nearly stock at 112, many other 264 type cams use 105 as the cam center, this lowers DCR by 2/10s. my DCR is 9.67. Using anyone elses 264 would make my DCR 9.93. My variables are below.Originally Posted by roadsailing
bore: 3.208
stroke: 3.031
rod: 4.803
static CR: 10.7 to 1
with my goals, I decided to trade some DCR for a bit of lift.

This is her first dyno run. The initial map was only written to 7500 rpm(engine and cams are good to 8500)
141whp @ 7468, 108#s wheel torque @ 6127rpm.
Engine numbers(back calculated by their dyno) 164hp @7468, 128ft/# 6127rpm.
Numbers very close to and in some cases exceeding blacktops. This is also her first pull, the new ECU is barely talking at this stage(I still can't get idle under 1500 in closed loop) I expect peak hp to exceed 150whp, and I expect peak torque to exceed 110#/ft also measured @ the wheels

umm, yeah ok, and this is relevant because....
Now THAT is emissions complaint....... SWEEEEET

do you guys have to do this every 6 months?
hahahahaha... no... the certificate is good for 6 months... note there isn't a plate.

ok i get it. we only have to 'roadworthy' our cars here once here in VIC and thats it - its valid for the life of the car - example my 1966 XP had its roadworthy in 1968 when my father bought it. technically it is still roadworthy - although its about eleventy billion miles from it.
thought I'd add an update to this...
The tune back then was still pretty bad.... it had a vacuum leak (using an AFM T/B instead of a MAP T/B you'll get that leak....) and a ignition map that was mostly undone, call it a break in tune only
this ignition map goes with the dyno run previously posted
a 2nd dyno run was done last year, around this time (Feb 2010) and she planted a bit more power
That ignition map was a bit more complete, but it also was a bit conservative
The ignition map has since changed....
To reflect real world use, and is now far more complete, and a bit more aggressive. There is no new dyno to show the improvements, but I do have 3 passes @ the local drag strip that tells some interesting information......
The short version.... she ran 15.77 @ 88.8 mph. Dig a bit further though and you see a car that NEEDS a better driver - the best reaction time I could muster was .716
my horrible 60 foot times, as compared to the overall run show that a better driver can likely make my car do passes in the sub 15 second range, and she should break out above 90 mph.
Not too bad for an emissions compliant 1606cc 4AGE, T50, and 3.90 open final drive.
