SSAC WG with race gas
 

anyone use the ssac gates with race gas?
How will the valve stem stand up with leaded gas?

Re: SSAC WG with race gas
 

I'm sure it will be fine. Got boost cut? >:D

Re: SSAC WG with race gas
 

Boost cut? I that where you get scared and lift off the gas pedal?

Re: SSAC WG with race gas
 

What does the wastegate have anything to do with leaded or unleaded fuel?!!?! :S

Re: SSAC WG with race gas
 

I believe Tial says not to use their typical 38mm gate with leaded fuel. I have no clue why, though. ???

Re: SSAC WG with race gas
 

I've heard of this too. It'd be good to know if it's anything to think about.

Re: SSAC WG with race gas
 

The lead oxide is corrosive and can cause valve failure etc.They offer another valve with a coating to prevent this corrosion.I would just run it and keep the boost cut hooked up in case.

Re: SSAC WG with race gas
 

my SSAC 38mm WG got a steady diet of race Gas :6

Re: SSAC WG with race gas
 

mine too, no issues. ---- it,

Re: SSAC WG with race gas
 

i have run 100LL avgas with no corrosion problems. the only problem i had was lead build up on the spark plugs that caused detonation

Re: SSAC WG with race gas
 

You run plugs longer than 500 miles? ???

:P

Re: SSAC WG with race gas
 

it didnt even take 500 miles to get them all loaded up with lead. it was like 200 miles

Re: SSAC WG with race gas
 

Sure it wasn't oil?

Re: SSAC WG with race gas
 

no, they were dry and white from lead. i am an airplane mechanic. i am used to seeing lead on plugs

Re: SSAC WG with race gas
 

I've seen oil deposits as off white to beige build up on the ceramic, actually look like it's te ceramic itself unless you chip at it or start forming bulges. It depends on how much you are passing, and how much of it is burning.

Offwhite build up --> ashy --> wet --> engine death.

The two cars we run race gas in get a fresh set of plugs every time they roll off the trailer. I really dunno how they wear. :1

Re: SSAC WG with race gas
 

JD, im not trying to argue. i hope you dont take this that way, but my engine doesnt smoke at all from oil. i did a compression test and got 170 accross all 4 cylinders. i get some black smoke from running rich under very hard load though.

the plugs in my car were dry and looked just like the airplane plugs i pull almost everyday. since i cleaned the plugs and stopped running avgas it has never detonated at all.

either way, i dont think race gas would be a problem on a wastegate.

Re: SSAC WG with race gas
 

I wasn't arguing, I was just stating the specific limits of my experience and knowledge, and wanted you to fill things in. Like I said, I have *zero* experience with long term plug wear + racegas.

How much power (estimated or verified) are you pushing? What sort of breather setup do you have?

Re: SSAC WG with race gas
 

sorry, i got the impression that you thought i was trying to argue with you.

i am on my 1st set of plugs since i went turbo so i also dont have a lot of experience myself. i am only making around 150-160whp due to my small turbo and lack of intercooler. i have a pretty nice log manifold that i plan to use with a t3 i am trying to get.

my breather is just the stock oil seperator with an open tube. i am also hoping that with this new setup i can make a real oil seperator system and have the inlet side of the turbo provide that vacume while under boost and have the intake manifold provide tha vacumme while not in boost. sorry about the spelling, i am at work and im not supposed to be on the computer. lol

Re: SSAC WG with race gas
 

Turbine or piston?

Re: SSAC WG with race gas
 

what do you think you ------- noob

Re: SSAC WG with race gas
 

No no, he fixes the golf karts that the other mechanics drive between hangars.

Re: SSAC WG with race gas
 

rofl

Re: SSAC WG with race gas
 

how would i know if he works piston or turbine

Re: SSAC WG with race gas
 

piston planes. moslt yi work on these two types of planes, but the company i work for will work on anything

we are a service center for these. just like being the dealer. we do warranty work and stuff like that

we sell these and we are a service center for them too(i have done work to both of these planes

Re: SSAC WG with race gas
 

looks like 172's and rv-8's??
my buddys building an rv-8

im not to familuar with the smaller stuff

the last thing i worked on

Re: SSAC WG with race gas
 

yea, the extra brand is very similare to an RV-8, but it is way more capable than the RV-8

Re: SSAC WG with race gas
 

wow thats gay ive never heard of that. Most quality race fuel is leaded, like C16... ive not heard of many people having trouble with the lead content and the wastegates, but maybe its just me

Re: SSAC WG with race gas
 

there might be more lead in avgas. the angines are old technology and need lead like an old 50's v8

Re: SSAC WG with race gas
 

i ran 110 leaded race gas through mine every day...i changed the plugs everytime i went to the track and then ran on those plugs till i went to the track again...race gas every day...never had problems with fouling plugs, or detonation. guess its all in the tuning lol...but yea the wastegate held up just fine, i prolly ran over 60 gallons of race gas through the motor (we have 110 leaded at the pump in idaho) :6

Re: SSAC WG with race gas
 

i hate you

Re: SSAC WG with race gas
 

we have 100 octane unleaded at one pump here in jax FL. i still think its the amount of lead in the gas. they call avgas low lead, but it has a lot in it

Re: SSAC WG with race gas
 

We have 110 at one pump by the airport. You are not supposed to dispense it into a regular car, you have to either have a container or the car traillered, but they usually don't care.

Re: SSAC WG with race gas
 

We have that here too. 110 octane cam2 at a gas station near the dragstrip. Doesn't seem to bother my wastegate either.

Re: SSAC WG with race gas
 

I've had 2 failures one on a tial and one on an SSAC both running avgas for an extended period of time. Both cars were over 300whp and running rich. The failures I saw were both in the pistons so they didn't result in overboost. In short the piston in the WG was eaten away. The tial failed after 3 years of hard use and I think the SSAC one was on his second year. Both had a lot of trouble with lead on the plugs as well. They've since switched to Stinson's Mk4 unleaded 114octane and I haven't heard back from either.
