The right distributor

[Dean]

Right I am at the stage were I need to start to think about getting the right distributor for my engine. But a few thing I am not 100% sure about.
Do I need a 25D or 45D. But I do know I need a vac I think.

Any how this is my engine spec

998 a series cooper engine +0.040
modified 295 head. Polished. Ported and larger valves.
SW5 cam
CR around 9.4:1
Twin hs2
S/S freeflow exhaust and a full twin box S/S system.

What would be the best distributor for my engine????

Been through the aldon site but still not 100% sure what's best. And also seen on the mini spares site they do original body's distributors but been modified by aldon.

Any help is greatly appreciated

Thanks Dean.

Who can tailor one for you if you give him your engine spec. It won't be as absolutely cock on as if you had it done ona rolling road, but it will be damn close. Swiftune will probably be happy to give you a suggested advance curve spec too.

I bought one from these guys. http://www.simonbbc.com/

They were very helpful, good value for money and the distributor has been top notch. They can do custom advance curves too.

thanks very much i will look into it and make a few calls

been doing a bit of searching, an now starting to get a bit confused.

my engine should have a 24d, or a 25d, i can get one of those with electronic ignition, but what about advance curves.

the whole "advance curves" has thrown me a bit, its something i have never really looked in to , or under stand much, how its worked out for my engine, or set/ adjusted . and theres not much online explaining it in a simple way?????

i have looked at the 123 distributors, they seem very good, but all seem to be 45d distributor bodies
also the same with the aldon distributors, they are all 45d distibutors bodies

can i use 45d on my engine or should i stay with a 25d distributor???????????

also looked at both www.simonbbc.com and http://www.distributordoctor.com/, they both can do me a 25d distribtor, and the distributor doctor can have one set to the right advance curve, but what should it be or is it something he would know.

or do i use a standard distributor and have it set when i get it set up correctly????

i dont want to spend my money on a distributor thats not going to get me the best out my engine,

so you can see, i am getting confused, too many choices and i dont know the best 1 to go for?????

so if you can help and shed some light on any of the above it would be greatly appreciated

cheers dean

Aldon 'Yellow'

[Dean]

ok, thanks, i take it by your short reply that this is the best, and nothing else needs to be said,

i have 2 other aldon dizzys but both for A+ engine, so i am very keen on them, but i want to make sure thats its the right choice,

so i take it that a 45d4 dizzy will work fine.

+40 997 295 ported head l/balanced 266 cam etc on mine. Aldon yellow works well, better than the 40819 'S' dizzy i tried.

[Dean]

good, almost the same engine and it works well, just what i wanted to hear,

thats made up my mind

cheers

Managed to find my old Aldon 100AR (red) dizzy earlier that was fitted to my A series 1.3, but that is a 43 D4 type with no vacuum advance.
