So I just hooked up my CO2 and i turned it on and I hear it leaking through the wastegates like crazy. If I put my hand up to dump of the wastegate I can feel the air coming out. I am assuming the bottom plunger part is what is leaking on the gate? If so how can I fix it? These are Tial 44MM gates.

 

I assume you have the co2 hooked up to the top ports, correct?

If so, sounds like the diaphragm has failed. If not, you are using the wrong port

 

You may need to pull it apart and add some hondabond to all the seals.

That's what I had to do and everything holds great now.

 

Anyone has somewhat of an idea or layout on how to make this work? Been debating on whether to run CO2 setup on our car or not.

 

Its cake. Instead of a boost source (intake manifold, compressor housing) to the input of the solenoid, your supplying it about 50psi of co2. So you would have a push-lock line from the regulator of the co2 bottle, up to the solenoid, out of the solenoid more push-lock to the top port of the gate(s). Then run your boost source to the side port of the gate(s).

Chad, check which port of the wastegate(s). If you have that correct either the diaphragm is pinched, or torn. In wich you can replace the diaphragm.

 

for today can I just hondabond the diaphram?

 

use black RTV

over Hondabond? Hondabond is the stuff, I even put it on a biscuit.

 

the C02 is awesome.... and cheap.... and reliable.......

 

Not to thread jack... Actually this may be beneficial for anyone using co2...

question...

My bottle regulator reads 25,000psi for actual bottle pressure. Then i have a 2nd gauge for line pressure which we currently have set to 50psi.

When i bought the bottle (2.5lb bottle) the gauge obviously read 0, after we had the bottle filled it only read 900psi Does that sound right ?
After 2 dyno sessions and 2 passes, bottle is now at 750psi

At what level should i be concerned with refilling again ? wait till it gets down close to zero ? or will the co2 setup not work as efficiently with lower bottle pressure?

Just curious don't want to be stuck at a track with no co2. So is there a general rule of thumb as to when to refill ?

 

I can't answer all your questions Jon, but you should refill it around 100-75lbs or so. You want to have a margin of over 50psi and who knows how accurate that gauge is....

On my Co2 tank I have 1,100psi. It is dependant on the source in which the little 2.5lb tank was filled from. Sounds like they were low on their own source.

Sounds like you are using a bit more than average. Most people can get away with a month full of weekends on a 2.5lb tank. Maybe even a bit longer....

Have you charged your system and looked for leaks? The old dish soap in water works pretty good when looking for air leaks....

 

Ok good info thanks Chris...with my 750lbs left i will be good for Etown.

 

For shure.... you should have enough for a few events.

 

You will be fine. We refill after every other race. We actually weigh the bottles.

 

are you putting it to the top port or the bottom port?

 

I am pretty sure all the Tials leak, I pressurized both my top and side ports and they leak like a ****, maybe I will try sealing the Diaphram with some Hondabond as stated.

 

If anyone is looking for a Less expensive CO2 setup. Go to your local Beer store. I picked up a 5lb DOT bottle for $75 and to refill it(exchange) its $13 and its open all hours of the night!

 

The top port should not leak. We don't use any sealant on it. We just keep a couple of extras, and pressure test in between rounds.

 

5lbs! that thing is huge. quartermax sells the best setup for the buck.

also it only costs 10 bux to fill a 2.5lb and it lasts most of the season.

 

You using co2 now?

leak on the bottom yes, top never

 

well my diaphram is not ripped so what do you suggest I do? I have a total of 12 dyno pulls and 50 street miles on the WG.......

 

isn't this why the Synapse wastegates don't use diaphragms?

 

Can anyone point me to CO2 on wastegates 101, pretty new to me. Thanks

 

You guys use liquid CO2 or only gas? My Dedenbear kit say (USE ONLY LIQUID CO2 )
