How many of you guys out there are running a Single Side Draught as opposed to a set of twins.
What sort of performance / happy / not happy???

I'm building a strong little A15 and I'm thinking of running a single or maybe even running with a 32/36 Downdraught - just to keep the cost down initially - even just to run the engine in.

How Available are Single sidies & manifolds for the a series & $$$

Thanx for any input.

knew someone who had a single sidie, he upgarded to twins though, "nuff said"

mind you i think the 32/36 is a good road car option, and is gonna be STACKS cheaper than setting up a single sidie

Yeah, I'm not tied up with the whole bigger is better thing.

It will be for a strong A15 street motor with full headwork, decent cam, fully balanced etc, oversize pistons(Not Forgies) etc etc.

I can't see any reason for a properly set up 32/36 to do the job - even for a while as I said to run it in even - then if the needs there go for the twins.

What sort of figures do reckon I'd be looking at with the above said mods?

NFI really, over 100hp at fly should be easy, could depend on carburation a bit

bigger is GENERALLY better at higher revs (dodgeman is gonna grill me for that), if you go for twin sidies you will get more power up top and therefore a higher maximum hp reading, but the low end could be sacraficed compared to a single side or downdraught

it really depends how its setup also

in honesty without mates rates or special deals, a 32/36 will set you back $250-300

twin sidies $800-1200 depending if you buy it semi setup for your motor and with manifolds, linkages, trumpets and socks or not

(prices includes parts, tunning ect ect, i.e. fully setup and running from scratch)

Whats the deal with fuel pump setups/regulators if i was to run with the twins?
Electric I'd imagine.....am I right.......more$$$

As I mentioned I'm really wanting more acceleration and off the mark power not so much top end power and speed - I've always believed in building engines for maximum torque and the rest should fall into place.

some use the mech pump it think, i had an electric pump with a regulator, pump was $40 regulator was $55, but i have found a place to get pumps for $10, you can get em at wreckers off some geminis and pulsars and stuff (should be pretty cheap)

I'm sure B120 will be here in a sec to tell me to stop being soft and get the twins

But When you sit down and plan a rebuild properly she soon starts adding up

Plus a decent set of twins and manifold ready to go seem so hard to find these days especially when dealing interstate

B120???????????

thats alright ill tell him to stop being soft and get injection, as i always do, o and to get a turbo not a super, and blow through not suck through, and to put a thermo fan on

hang on a minute, i dont think he listens to me much

oh, and he's piked on the SR20VE plans he had

hehe, that should get him going
