Wow, how much boost?

blackonorange 10-28-2012 08:17 PM
I'm shocked, those are huge numbers on a 7at

blackonorange 10-28-2012 08:28 PM
Man, im so pumped for you,

Those were all done with no meth injection. So with ripping out the cats, fixing the piping issues and changing out the plugs this seems to be the final set up to get this system to work. With no help from STS I might add. I've had to fix and trouble shoot everything for about the last 7 months. So the kit will put down the power with a few tweaks.
how much boost?

Boost was set at 9psi...I didn't run the low boost since it was a simple dyno dash. It was also about 40degrees f outside

What would you like you know about my set up? Blackandorange

blackonorange 10-28-2012 08:36 PM
What piping issue tower?

blackonorange 10-28-2012 08:38 PM
Also what kind of test pipes?

I had massive leaks due to the clamps they send with the kits. I went with a more expensive splice piece, can't remeber the name of the splice kit ($75 a coupling). But removing the cats is the biggest thing I have done that showed the real power of the turbo.


Berk test pipes...no resanotors though... I wish I was able to grab yours

Isamu 10-28-2012 08:44 PM
9lbs.... gosh... but I suppose your engine bay temps are good... what about oil temps

Chinook 10-28-2012 08:46 PM
Nice to hear that you got your problems resolved congrats! Could you get more info on the clamps?

Haha! Damn I just sold mine!!!! Now I wanna try em out. And leaks in the exhaust side or charge side

Of course like most of us that are turbo charged. When it's above 93degrees it will over heat quick if I'm getting on it. At the same time with the cooler weather it runs about 180 to 200. I drove the car about 30miles to the dash and the temp never went about 180.

Also the vented hood I have helps realease the heat. I had stopped at a light and everything was blurry due to the heat coming out of the hood.:tup:

My tuner was the one who fixed my leaks but I'll ask him what they were.

Both sides...mainly the charge side. I had him weld the exhaust side together in a couple spots but still to were I could remove the piping. Now to just buy a remote mount oil filter kit. That's a beating changing that filter.

Is there a way you could post the whole Dyno sheet? I'm so stoked man

I don't go over 200 under spirited driving, and never over 220 on hard driving, that's why I asked... tho my engine bay temps get pretty toasty LOL

Yeah living that far north I'm sure the 90's isn't something that happens for months on end like here in KC...and I beat the humidity is a lot lower.

Ok you might have to piece it together but this is the whole thing.

Once I get it dialed in and cleaned up it should look a lot better. This is still a can tune from STS:tiphat:.....So once I get the correct injectors for my meth kit I have that tuned into the car as well.
These were ran on 93 octane pump gas from BP not race fuel just in case someone wants to know.

I'll have to ask edub if he did a video of my car when it was on the dyno....can't remember. I was to stoked to do it after the first run.

blackonorange 10-28-2012 09:43 PM
Good for you man that looks awesome

SharpByCoop 10-29-2012 07:15 AM
I'm pleased for you. After all that, the provided components were at fault. Shame on STS for blowing you off.

The setup is strange, but effective. When built correctly.

Good for YOU!

Coop

Thanks. It's been a difficult 1 3/4 year...$10,000 + build and some loss of hair and some graying of my hair.
Removing the cats is the way to release the power for this kit.

Mr&Mrs 10-29-2012 11:36 AM
Glad you have things going in the right direction finally. From what I understand CAT's are not the safest thing to have in a RMT anyway.

weiboy718 10-29-2012 12:12 PM
Even on a regular turbocharged car is not too safe to have cats on. I've heard some stories like the cats material getting sucked into the turbo and destroying it. Some particles even made past that and damaged the engine.

Just things I heard about having cats on for turbo cars.

king12sky 10-29-2012 02:06 PM
I guess ppl in CA will nv hit those numbers on everyday driving. lol! poor o'91 octane!

How exactly would the catalytic converter components get "sucked through" the turbo into the engine?

With RMT, cats are definitely an unnecessary risk to the turbo, though, no question there.

You know, I was wondering the same thing, but that topic has been beat to death on this board so I just left it.

Honestly if you know anything about cars or hell even have common sense, cats getting sucked into the engine can't physically happen.

Right. I'm really surprised it didn't damage my turbo when I burnt them up and when I say burnt them up I mean it melted the screen guard inside the cat. So where that sh*t end up at is beyond me. Hopefully it got caught up on the out flow side of the cat.

Removing them just releases the air flow 1000%.....and the noise:tiphat:
The car is now more or less straight piped.

dude, I have seen some pretty outrageous shit happen.. but never seen a cat get sucked into an engine... :bowrofl:
I was just sayin, Red knows his stuff, for the people in question

I can see it getting sucked into the turbo on a RMT kit but I'm pretty sure it's gonna stop there and not cycle back through the innercooler then into the engine. Maybe it's the "magic bullet" theory for car guys.:ugh2:

I've actually seen it happen, although almost exclusively on cars with pre-cats that are right on the end of the headers, and only when initiated by core failure

:werd:

The turbine and the compressor aren't using the same air. I can't imagine chunks of cat hopping between housings:icon17:

You can look at a picture of a turbo and pretty quickly figure out that core chunks aren't going to wind up in the intake.

Huh? You've seen it happen ? How ? I don't understand how they could get in the engine

The short explanation is that there is some overlap between intake & exhaust valves opening. There is vacuum in the cylinder, and backwards airflow (backflow) is pretty common, generally sucking some small amount of exhaust gas back into the cylinder. In cases where a cat (again, generally a pre-cat because of their proximity to the exhaust ports) has broken down, you have
A) loose pieces of honeycomb floating around
B) significant increases in backflow

and it becomes technically possible for cat material to flow back into the engine.
