Helping My Son With His Project

[Adam]

Peak power is made around 12.5 but your AFR's can be spot on and the tune still not be safe.

For just getting around I would say it would be fine but I wouldn't push it to hard without getting it tuned properly. No doubt you would know that anyway being one of the more experienced guys around.

Yeah in the hot conditions I'd keep it down to 12- high 11s... and just don't have the timing to far advanced.

Its more so overly advanced timing and to hot air charge temps that destroy motors.

The motor sound like it should take 15-18psi fine... I used to always run 15psi in the stocker motors and they were happy.

300wkws isnt hard to get with these motors, there's alot of them in the high 300s with the bigger turbos.

I'd be seriously looking at using that ED/EB inlet manifold you have there... they flow well and have a resonable plenum on them... much better than the EF one which is the same as the XR6T one ( minus the butterflys of coarse )

Yeh, we wanted to run the ED/EB inlet but there was going to to much work involved with the A/C. Plan to eventually use a different plenum similar to Nizpro or something.

thanks for the advise

Hi macka my brother was looking at putting a turbo on his EL, just wondering what this project cost you?

thanks

Nice clean looking car.. Bit of a sleeper

[Mr Man]

saw your young fella driving up deakin ave on saturday arvo, looks good, I love the old EF/EL especially with a turbo

Hi guy's it's been awhile so I thought I'd let you know what's happening with my son's EL conversion. Since we last posted we have installed my EMS stinger that I had on my XR6Turbo and fitted 42lb injectors. I've basically been doing some cold and hot start tuning and some cruise tuning. I'd say even with my basic tuning knowledge skills the car has increased in power by a good 40rwkw. I've kept the A/F ratios fairly rich at around 11.2 on eccelaration pulls. Timing advance @ 30 deg. No pinging yet, even in Mildura's hot weather. We have'nt played with increased boost yet either.

We plan on putting back on the dyno once we finish the new intake. We may even wait a little longer till after we fit a new plenum chamber. Which reminds me I must ring Pazaman and maniac they have something of interest.

I scanned the base dyno run still using the standard ECU and injectors and rising rate fuel reg. We tried 2 runs had to do one in second gear because the auto wanted to keep kicking back down from third gear. We eventually got a run in 3rd buy ramping up slowly until we reached 140km then give it wot. both figures were pretty compariable both producing just under 180 rwkw @ 6.5 psi. Torque is a very impressive 1200 nm still looking for this dyno sheet to prove this figure will post if as soon as I find it.

I'd be interested in your comments and we look forward to putting it back on the dyno soon once we finish our other mods for a more serious power run.

Bugger does anyone know how I can rotate this pic

[our06t]

sounds like a good project

keep us updated

Rapid what would you consider safe A/F ratios under load. Mildura is pretty hot this time of year high 30's low 40's most days. I've heard 12.5:1 but I'm thinking closer to 12 would be safer.

Erm....you are allowed a pretty wide window on AFR's, it all depends what timing you run at any given AFR.

You will find your motor will most likely make the most power at something in the 13:1 range, maybe 13.2 to 13.4. What will be important though, is to run 100octane fuel, and then dial in your timing to optimize the setup at that AFR - where an engine makes optimum power varies from engine to engine, but 13:1 is a good place to start - start leaning out a few notches, and play with the timing, it would be good to use a stetoscope to determine the onset of detonation at any afr break-point, but this method will require a fair bit of time on the dyno.

Don't venture near the lower 12's, frankly, it's a waste of fuel, additional wear-and-tear on your cylinder walls, and bad for emissions.

If a tuner tells you that 13:1 is bad for your engine, find another one, as that one is no good.

I luv what you're doing to this setup though, it looks mean, and will go like stink - good luck to all those crappadores out there, there's a new animal in town
