Discussion , Boost N' Carbs - Blow & Draw Thru Turbo / Supercharging

[Acid X]

I've read that in order to do turbo you have to do the EFI swap. Why is this? I mean, we can use a supercharger on our carb, but not a turbo? I mean, i think it would be cool to turbo a carbureted car.

So, what's the take on this?

Search into a Blow-through carb'd setup

Sounds interesting.

Just about everything I found is here:

Yes you will have to scroll down to find the part on turbocharging carbs.

Or it's in Project Central

Interesting. So what's the best way to go about this? I mean, pull through seems harder to do than the blow through. Pull through has to handle the fuel/air mix coming from the carb. That doesnt seem too good. Then with blow through you have some serious spark/fuel management problems.

me and a buddy are in the middle of doing a turbo/weber/b2015 convrestion in his lude, theres a few things were working on and once its done hopefully i can post some pics and explain any problems we had

[Acid X]

That'd be pretty helpful!

[b8er]

ooops , when i wrote b2015 i mean b20a5

[A20A1]

you know you can always edit your post.

Any update on that turbo project, b8er?

I'm really wanting more information on turboing a carbureted car.. I think that blow-through would probably be better than pull-through, just because of how much easier it would be on the actual turbo unit.. I wouldn't want to pass an air/fuel mixture through my turbo, that's for sure..

I was under the impression your carb had to have vacume opperated secondies

what kinda supercharger availibilites are there?

Supercharger

8-14 PSI
Grab a Procharger C-1
Get it in reverse rotation if we need to.
Our Accord has 9.1:1 CR
Clean out the combustion chamber to get rid of the carbon buildup.
get a carb built for boost.

For carbureted motors, the rules are slightly different. Carburetors deliver the vast majority of fuel in a liquid state, and as this raw fuel atomizes from liquid to gas, a chemical state change actually occurs. Due to this endothermic reaction, which draws heat and cools the incoming air, a carbureted motor can safely handle more boost than a comparable EFI/TPI motor. For carbureted engines with compression ratios of 9:1 or less and boost levels in the 8-14 psi range, pump gasoline works very well. Compression ratios of 10:1 and higher require lower boost levels, higher octane fuel, intercooling, or some combination of the above. Compression ratios in the 7or 8:1 range can usually handle 12-20 psi on pump gasoline.

If you look at it, he turned the exhaust 'down-pipe' from the header up, to power the turbo, then made a turbo downpipe.

whoa nice!

[EricW]

looks good, More pics.

[snoopyloopy]

nice. now someone just needs to stick one on a ca5 accord. and how does that work as a drawthrough? it looks like a blowthrough to me.

[Cheeseburger]

wow thats awesome!!! more pics!!

[MessyHonda]

yup looks good....NEED MORE INFO

[bobafett]

fantastic!

[AccordEpicenter]

very interesting, thats def the first time ive seen a setup like that on an F22. If youre gonna go even more hardcore with carbs you should probably do a blowthrough and get a bigger turbo but its nice and different what you have

[snoopyloopy]

ook. i see the suckthrough now. it makes more sense. i'm not used to a carb looking like that. and i was (and still am) pretty tired. but it looks good. even better, now that i see how it actually is set up.

[A20A1]

Looks good.
Let us know more about the ignition setup once you finish it.

Also what kind of fuel pump and fuel pressure reg if you have one.

[MessyHonda]

i think that would be kinda neat but then how about if you crash....all the compressed air with gas could blow up and start a fire.

[gfrg88]

nice thanx for the pic
