In my experience with the 450 radial I knew full well there was a lot more that could come from the engine if it had a better intake arrangement. As the FG84 is basically the same engine with larger pistons im not at all surprised that it had the same issues. Also the mod done there is very good and very simple, it also does not open the intake stroke to the crankcase area as the mod for the 400 does. I must say though that bushing the big end is, to me anyway, a great idea. I do not know why saito don't do it any more. Also, given the simplicity of his intake why didn't saito do something similar? I think they need to spend a little more time testing

Would any of the 450 mods (or similar) be usable on the AR400 ?

Hi guys, here is a video I just did on a ASP 400 running on Gasoline an CH single unit CDI. Units will be available in mid Summer 2014.
The biggest issue I have is to find enclosures for it.
Engine runs decent on gasoline with original carb...just tuned for gasoline.
The CDI runs on 6-6.6-7.4 and 12v. can also run on Moki all 5 cyl series but need to make the necessary hardware to mount the sensor and magnet ring.
What is the performance you getting on the ASP 400 running on Glow and what prop?

Thats great Adrian....I want one of those ignitions :-)

In this video it is said that the gas/oil mixture is 20:1 which makes only 5% oil content. I wonder how long this engine will last, because it has not the modified backplate and there is only little oil going into the crankcase, which usually is quite dry even with higher oil contents. And what is about the cooling? Gas engines usually need larger cooling fins compared to methanol engines.

Carosel43

When you say the original carb is tuned for gas, what exactly do you mean as normally the jets would been to be made smaller to make it work.

Also I still do not believe that lubrication is an issue when then engine is being used. if it was an issue they would be seizing up all over the place. I also do not believe that the intake mod enhances lubrication in any way and to my mind would actually make it worse due to the thinning of the oil and recirculation of contaminated oil. In the testing I have done with my engines 40:1 has so far been fine and I will soon try 50:1

EQ1

So you say that you are running your ASP400 with 40:1 ??? 2.5% of oil ???

Carosel43

No I have converted some Laser engines to petrol for my own curiosity. They are running on 40:1. My 400 is running 20% oil as it plugs all the gaps in my mechanically ruined engine. Sorry if it was not clear

The Seidel and Moki engines use the open style intake system like the one Olivier Rogeau designed for the FS-400 so I figure there must be something to it.

The engine used by CH Ignitions has an amazing low idle. Very impressive. I am a bit disturbed however, by what appears to be heat damaged exhaust pipes. It looks like the chrome plating has been severely scorched by exhaust heat. Could this be a potential issue?

It looks like the nose case has been heavily modified to include the pickup system. Would a kit for the FS-400 require this modification?

Just converting to CDI W/glow fuel will raise CHT moderately. A full on gas conversion will raise it significantly more. I did comparative tests monitoring CHT for GI/glow fuel, CDI/glow fuel &CDI/E-85.

Adrian's conversions are usually bolt on, requiring no modification. I think the engine in the video is probably a prototype.

Carosel43

Tom, I spotted the cooked pipes as well. I wonder how long the Chinese metallurgy will tolerate the heat and weather its just the pipes. they are very thin

Hello Guys, Sorry for the little delay.

Here are couple things that I should mention.

The ASP 400 In the video is a Old engine.
The Pipes where like that when I got them.
5% Oil is fine that is what Saito is using on all FG Series. FG14/17/20/21. The FG36 it had a brass bushing in conrod.
But all of the above uses just AL on Steel .
The crank case was not modified at all, I have the sensor ring that gets press fit on the little lip in the front of the case and I use my best friend JB weld to give extra strength,
Bill Carpenter use it for the last 30 years and he said that he did not had one coming off.
I look In to the bolt on for sensor ...but will be to big stuff coming from the case bolts, it will need to be heavy to withstand vibration and have the sensor in 100% @ 30BTDC.

The Carburetor was not touched, it is 100% stock just leaned out on LOW and Hi to run good.

I have a OS 5 Cyl That I will do next and I will post a video.
Over the weekend I made a EVO 7-77 and is on Youtube you guys can watch if you go there, I will not post here since is a ASP Thread.

I am thinking to open a CH Thread and Post there All the info with all the stuff I do as Info.
I may not be able to answer all times since I have a FULL time job and after 4PM I work on CH till midnight.

Here are the pictures of the new Magnet ring and Sensor Ring Also a Saito 450 Idea that I will try, I was thinking of this for a long time ...but did not got the time to draw in CAD and do it.
I will try it some time next month.


If I miss anything ask me ...again.

Thanks
Adrian

OK Dan, here you go....hope I will not get in trouble.
Are 2 of them if you go to the youtube.
This is with 3 blade 25x10 and the other one is 24x10 Xoar

What he heck are the cone & funnel shaped items?

CH Ignitions

My Feedback: (11)

This is what I did years back on a Renault 12 that was terrible with fuel mixture.

The cone goes inside chamber, the step cone inside the funnel.
I will not go in full details. on how and what.
The inside plenum is modified, I did not post the picture of that , this will be V1 and then I have second Idea, V2 to test out.
It will be trial and error and learn from it. It will work definitely better that the OEM I can tell that much....LOL

Yeah, a little confusing showing Saito parts when discussing the FS-400. lol...

Heya Adrian

I put my hand up a while back to be a volunteer to trial one of those ASP CDI ignitions to perhaps give a different perspective on how it all works from a more novice point of view. What happened to that idea?

BJ

My Feedback: (11)

Hi, I did not forgot about you, But first I need it here in USA to make sure will work.
But you will get one Kit to install, Give me couple weeks and will do it.

Thanks
Adrian

Carosel43

As my 400 is not long for this world in its current form I could try a conversion. if it blows up I don't loose much

BJ64

That's great news, Adrian. Looking forward to it

Caro - why do you think it would blow up (other than it might pull a heap more revs)?

BJ

Carosel43

I fear it will blow up as its already done that 3 times!

BJ64

Meh - a Ledge like you will get it going again
