Re: Australian L67 build

I have just completed half of a top swap on my old engine. By half I mean the cylinder heads. I went to work a few weeks ago at a new school and on the way in my engine developed a problem and was running extremely rough. I babied it home in the afternoon where it promptly spat off the bottom radiat...

Re: Idles at 1250 RPM

The link should be to a YouTube video titled "Toyota 3TC turbo propane first start" posted on June 17. Should it? [youtube]https://studio.youtube.com/video/r0dni6K6NSI/edit/basic[/youtube] The link doesn't go anywhere and looking at the link address if I signed in as you I'd be taken to your YouTub...

Re: Idles at 1250 RPM

The link you posted doesn't go anywhere except an error page.

C3H8 is spot on, spray a liberal amount of soapy water or brake cleaner at all gasket locations and listen to the engine. When it changes you have found a leak.

Re: Propane fuel level gauges

In Australia, and I assume most other countries, you can buy various propane gauge senders. Each sender works with different gauges depending on their ohms requirements. Common senders in Australia are listed here https://bluelpg.com.au/shop/electrical/ ... s-lpg-tank

Re: 454 turbo impco 425 x2 tuning help

Stock heads, forged pistons balanced bottom end. Approx 8:5 compression ratio. Comp cam turbo/supercharger camshaft. Don't take this the wrong way but I'm done here, I can't help you with anything when the information you supply is less than basic. Let me give you an example of the type of reply I'...

Re: 454 turbo impco 425 x2 tuning help

It's running a 2.78 rear gear ratio and a standard turbo 400 transmission and convertor. And you want 700RWHP? You'll blow it all apart unless things are beefed up. When I asked about the combination and then specifically asked about what parts the engine has I was referring to heads, compression, ...

Re: 454 turbo impco 425 x2 tuning help

If the turbo is spooling at 2400 rpm (200 rpm higher than before the change you just made which to me is a great leap sideways if not backwards) and the engine isn't responding to it until 4000 rpm I'd suggest the build parts combination could possibly be a problem. We know a little bit about the tu...

Re: 454 turbo impco 425 x2 tuning help

Please don't take this the wrong way but there is very little real information for me, or anyone, to be able to give accurate and helpful advice. Twin outlet definitely on to do list. Will see what my tuner says if he could do it You need a license to work on LPG systems and if your tuner isn't lice...

Re: 454 turbo impco 425 x2 tuning help

Single outlet t'd to twin lines. Change this to twin outlets of at least 8mm, preferably 10mm, lines right through to the regulators and this job will be so much easier. High flow lock offs. What brand and model? Twin model e's twin 425s. Good. I'd be happy with a cruisy 10psi for now. For the turb...

Re: 454 turbo impco 425 x2 tuning help

As I mentioned in the PM I am not all that knowledgable with regards to Turbos BUT I can say you inlet track is way to small. As a comparison the L67 that I am building is 3.8 litres the Eaton M90 will be putting out at least 1 Bar of boost so the L67 would be behaving as though it is twice the size...

Re: Lean out at WOT. Fine at 3/4 throttle

Let's be frank (not Frank) here. I had actually given up on this. This is an issue that has been going on for quite a while. I can understand, due to the current pandemic, if this was a recent thing that getting parts would be difficult (I order a battery for my wagon a week ago and it probably wont...

Re: Australian L67 build

Thinking out loud about air and fuel flow for the L67. These are 3.8 litre that can be stroked to 4.2 litres. There is at least 1 Australian company that builds them to 4.7 litres but I think the rod/stroke ratio may put to much side load on the pistons/bores because they are a short deck block. The...

Re: Image Size Revision

I resized the images to 1024 x 768 and they uploaded successfully with that so I thought you had adjusted the size limitations already. If you haven't adjusted it already I think the actual limitation is how many kb the image is not how large it looks physically. I asked on another forum (L67torque)...
