I've done a search trying to find out how to do the whole CO2 setup and did not find anything that showed you how to set it up. I pretty much know the concept of it and I was hoping that someone could elaborate on how to set it up .

Thanks

 

If you are talking about the Co2 set up for the boost controller then I think I might be able to help you. You install the boost controler like the instructions says except for the port for the boost control solenoid that goes to the Manifold pressure, this port is hooked up to the Co2 instead of the manifold or boost pipe....thats it.

 

what size bottle's do you guys use. I am sure a 5lbs bottle is a too excessive, I was wondering if a 2 lbs bottle is moderate?

plus, does it matter how far the bottle is from the wastegates does it?

 

The distance from the bottle to the solenoid won't really matter.

 

We use to us a 5 Lbs bottle and the distance between the bottle doesn't matter, just make sure you have enough pressure. We managed to get 50psi without the Co2 set up, so we got rid of it.

the only reason i found out to run c02 is that there isnt any....except to open the chute.

You should know better than that.

No benefit? Thats crazy.

 

If your turbo is sized right, you don't need co2. I can make from 10psi to the most the turbo will make w/o co2. The times where you need it is if you have a small wg spring and alot of exhaust backpressure.

 

There is no way that manifold pressure is as stable as regulated co2. Ive seen plenty of datalogging. Sorry, Tony.

Sorry but I have to agree with tony on this one...from our experience not from hear say.

 

I'm using AEM EMS to control my solenoid. I know you are using the innovative, is it a different setup? I just found something on honda tech saying that you should run the CO2 in line to the top port of the wastegate. I'm sorry I'm confused on what port I should run the CO2 to.

 

from what i heard c02 is more consistant and reliable. Needed is more of a personal reference. i dont need motec but i sure do like it.

are you guys going to irwidale soon? i need some sig's?

Of course it's not as stable. Do you understand how a PID controlled boost control works? It doesn't take a constant input pressure to have stable boost. Trust me, i've setup a couple more boost controllers on race cars than you have.

If you don't know how to properly setup a PID controller, then a constant input pressure will make things easier, but doesn't mean it won't work the other way.

 

I love the co2 setup we ran for the last couple of years

without it we could only make about 26 psi with the gt4067 turbo with our low wastegate spring pressure that we ran of approximatley 10 psi.

with the co2 we could run as much as the turbo would allow (approximately 34 psi).

it worked wonderfully for us.

we ran the co2 through the boost controller solenoid so we still had full control of the boost pressure through the motec to target whatever we desired

it takes some fine tuning on the co2 pressure in order to not hit the wastegate too hard upon turning the co2 on and spiking the boost -- we generally set the co2 to about 7-8 psi more pressure than our targetted boost pressure

That's exactly the application it works good in. If you guys had a bigger exhaust housing/wheel then you would have been able to get the same results w/o the co2. I can max the 42 compressor with 11psi springs and no co2 on my car.

I generally prefer not to use co2 unless it's absolutely necessary, it's one more thing to go wrong. We've lost races in the past from either running out of co2 or forgetting to open the bottle.

Exactly, and it's just one more expense to absorb. I'm really hoping once I get my car done and dialed in that I won't have to run Co2 to make 40-45psi of boost. I'm going to be running the World Electronics PBC-1....what do you think Tony??

Its a 2.3L with a GT4294R 1.15A/R, with a 44mm 20lb spring Tial wastegate

I ran Co2 on the racecar and it was more of PITA than it was worth. But what works for one person, doesn't work for all.

 

I think you'll hit your target with 20psi springs. If not, throw a bit more spring in there, it's not like you need low boost in that car! lol

 

I do know how it works, but it is still an ebc that uses a target boost.t There are a few variables from track to track and the majority of racers don't have the option of different turbos. If someone was to run here in Pomona, they can't take it out to Utah with the same setup on an ebc on manifold pressure and expect to see the same results from their turbo. Co2 gives you a hand in making up some of that difference. I've done a lot of research and talked and reviewed data with some of the best in the industry to come up with the boost controller in out car. I didn't just rely on what I thought. I know you've got your car to haul *** and you have that thing dialed in but I think the co2 setup is a better way to go.
