rev210 FINALLY books a dyno session!

[GTS-t VSPEC]

Yeah, I was there, it made impressive horsepower considering the retarded timing, hope you get the knock fixed soon, then we can push it harder:D

See'ya:burnout:

I found out I'm not to blame for being an idiot self tuner.

The problem (knock/ping) seems to be a single piston issue. We suspect a blocked injector or two. The afr's are super rich as I have previously dialed in more fuel to cushion any potential damage.

The result was a ping at about 4700rpm that prevented us reving it any higher.power: 230 rwhp - afr : high 9 with very little timing advance

170odd rwkw with 9 a/f ratio?? so ur car is a freak then!

[rev210]

It does have a Cam gear and some other things done to it. The engine is relatively healthy too.

I might rip the injectors out tonight and run them over to an injector joint tomorrow.

Dave,

230rwhp (172rwkw) @ 4700 is bloody impressive! Given that peak power isn't till 6800 stock. If you've dialed the HKS cam gear for more top end then the peak might be even higher?

My estimate of mid 190rwkw is lookin' good It might go even higher!? Especially when you're running conservative timing & nasty rich.

While on the A/FR's, 9:1 isn't very healthy @ all You might have dialed in a little too much cushioning! Not quite as bad as too lean, but still not good.

9.0:1 gonna foul plugs and exasserbate the problem you're having??? Dunno...

[rev210]

yeah I am being carefull about the fuel issue. Basically the bad afr is right on the ping line so its not doing any harm on my day to day driving, what I am resorting to given the problems up top.

Yepp, just as we thought, Rev's got one of those freak 1995 cars :uh-huh:

It's good to see that the ping issue 'shouldn't' be anything major.

Are you getting them cleaned using the ultrasonic bath way?

Once you get the ping sorted, and back for a re-tune, I reckon you'll see your 12 second pass :uh-huh:

Well done

If he doesn't pass out from PULP fumes in the meen time

It's not a freak car.

The first dyno it ever had (over 2 years ago) showed 180 rwhp odd on a dyno day with other cars and whilst a heathly figure it wasn't the highest.

the mods and tuning I've done are responsible for the power and considerable torque it's making (afr's uptop aside).

So let me get this rite? 170rwkws at 4800RPM????

DAIM.

Mine's a 95, but it's no freak, hell I can't even pull the 1/4 in less than a 14 right now... so bleh!

considering dave ran a 13.4 without the AFC, i still cant see what i'm doing wrong...bleh!

[GTS-t VSPEC]

Kym,

Maybe it's driver related?:bahaha:

Pretty respectable figures considering engine mods are turbo back exhaust, panel filter, thermal wrap, 10psi, cam gear, afr of high 9's (untuned s-afc), and a little advanced timing (did I leave anything out?).

I'd be happy with that, that's for sure

Most people get less than that with a 'professional tune' at a workshop

Rev - are you getting the injectors clean by an ultrasonic bath?

Cheers

J

[GTS-t VSPEC]

Yeah, I think he's going the ultrasonic bath then flow testing:D

See'ya:burnout:

[adam 32]

paul; was it a similar scenario to mine?

[GTS-t VSPEC]

Adam,

Yeah, I think it could be. The overall AFR's were fine but still pinging even being retarded. Looks like one injector is lean.

See'ya:burnout:

While I think my car is a Tuesday car, but with a Friday driver :bahaha: :bahaha: :bahaha:

[whatsisname]

My car's a Friday arvo special with an all week driver

[adam 32]

paul; pulled the plugs and they ALL show signs of running lean (i think i told u already...) so despite steves dyno sayin its rich theyre ALL white

weird
