New project

Hi Al
thanks for the pointer on the front axel, 3mm wall it shall be, about 1.5" diamiter? I got back from seeing Roy at lunch time, he is trying to talk me into running in his outlaw supercharged series. . . from the first year when I said it would be too much to jump in that far first season he just sais "don't worry about it Mike, we'll show you what to do". However I think it will be wildbunch the first year (it will be 2012 before I have this done I'm afraid, maybe one showing the end of 2011). Roy also said the pro et was very competative and I would be "cannon fodder" for the first few years if I went for that series, he said the outlaw supercharged series he ran gaurenteed 4 competative runs at any meeting. What is it with methanol and supercharger guys, the worlds worst pushers!
To run methanol don't I need alot more compression, I am only running 11.6:1 and though I have a low overlap version of the cam I am still running quite alot of timing, surely I need more like 14 or 15:1 for it to burn properly?
What does "flowing" a methanol system involve? new term to me is it having the system run up on a test rig of some sort?
Many thanks for all the advice so far, next year I intend attending all the wildbunch events I can get to to meet people and pick as many brains as I can, I hope to see you there.
Best regards
Mike
PS Tom, you must be laughing youself silly at all this, you thought I was bad at leading people astray

From my karting days Methanol could be run instead of petrol (avgas for best results) but you could not swap over and to do so you needed a different carb that was jetted and flowed about 1.5 times as much methanol as you would use in petrol. (Better power though)

Also don't breathe the fumes - from memory they are carcinogenic.

When using methanol and if you want to run an upper cylinder lubricant you have to use Castrol MSSR instead of castrol R - The R will not mix with methanol.

Also methanol is very short life and draws in water from memory (Even out in dry old Zimbabwe)

Thanks Ian
From what I've read already methanol is very bad for your kidneys, skin and retina and is absorbed straight through the skin. . . smells great when passed through an engine and makes a loverly crisp engine note. I will be running a mechanical fuel injection and will need to get a set up for this fuel if I go that way, on the current plan that is a decision for june/ july time but if it works with the rest of the engine as is I think it is worthwhile long term.
Best regards

Couldn't resist keeping it a secret any longer then Mike! Cant wait for some pics and progress

Hi Tom
I'll post up some pictures on Sunday when I get my hands on the chassis.
best regards
Mike

[kiwicar]

Bad news today, I can't now pick up the chassis this weekend, the chassis inspector can't get down to inspect it until the first week of December so I can't pick it up until the second weekend .
I might be feeling a little frustrated you know!
Best regards

be worth the wait though mate

Hi Mike,

Flowing the system is just that everything is calibrated against a known standard. The most important thing is to know the actual output of the fuel pump from that you can easily calculate any changes you make to the system. We ordered our system and paid an extra $300 to have everything flowed. We got charts of pump output, nozzle flows, we ordered a couple of spares and they were flowed as well, each nozzle is letter stamped as well as its nominal size so for fine tuning we can juggle things around. More compression would be better but 11.6 will be fine, more compression will make more power but you will still make more than with petrol at that compression, you just don't want it in the 9-1 range. 11.6 will also be absolutely perfect for when you bolt the blower on. Mechanical injection is quite simple to tune but not easy to really fine tune it. With petrol you really have a very narrow tuning window in terms of air fuel ratio and timing without detonation, with methanol these problems go away, and you are not at the mercy of the oil company scientists, not all 98 octane petrols are good!!! All clean dry methanol is good.Methanol is also just one component unlike petrol which is made up of a blend of base substances with widely varying properties. A/F ratio with methanol can vary from around 4.5:1 to 6.5:1 with very little performance difference, try taking petrol from say 12:1 to 14:1. Have a read on the subject it really makes sense to run Methanol.

I stripped down the 9" third member yesterday so I can clean and paint it, anyone recomend the best way of getting the old peeling paint off the outside, I could get it blastedbut I am worried about the person doing it blasting the machined surfaces. Can I use nitromorse and do it that way or will the sand cast surface of the casing hold too much of the chemical and stop the paint keying?
What is the best primer/ paint combination to use, it will be getting hot but probably no hotter than a block?
best regards

mike when i did the mussie,
i used a thing called a DBS and a grinder with wire wheel,

Thanks Tony, Ive got a wire wheel for the angle grinder, not sure I'll get it in all the webbing bits but I have emery cloth, I'll make up a cover plate for the machined surfaces. Have you ever tried to lift a 9" third member by the way? it must be over 20lb stripped!. Any ideas on paint?
Best regards
Mike

theres a paint out thats like smoothrite/hamerite but dries quicker,
i have some satin black that the mussie will be painted in once finished, can find the name out for you if you like?
its harder wearing also.

Hi Tony
"theres a paint out thats like smoothrite/hamerite but dries quicker,"
Yes please sounds like what I am looking for.
