2011 5.0 76mm Hellion Results

[KenB]

Got this done Saturday. This is with the 76mm upgrade with a 6 lb. spring. Actually made 8psi. Up top we were getting boost creep as we think the wastegate may be too small. Still very happy with the numbers. Vinny (owner) is going to upgrade to a larger wastegate and then we will retune.

awesome stuff Ken,


Ill call you later!

I like your dyno on the bike even better though...lol

For those of you that like to analyze dyno graphs, you can see the jump in boost. If we stayed in it, we saw a lost of power. We are considering a valve spring issue. But the wastegate for that turbo is on the small side, so we are going to change that first.

If that doesn't clean it up, we will measure back pressure.

What's the most boost you think you can run on stock motor. We just ordered our hellion Turbo kit, still waiting on it.

Stick or auto?

Where is the wasetgate signal source tapped in? Turbo outlet or post intercooler?

how long will the stock motor last at these power levels?

Nice!

Ken, what was the HP @ 6500?

I'd have to pull the graph up but looks like 625 from looking at that graph.

I really didn't spend much time trying to get a lot of power out of it as it was performing better than expected from the start. Was more concerned with the boost issue up top and concentrated on that. There is probably more left in it.

That is incredible. That kit is the reason I'm not getting longtubes ; )

I already have LT, but will prob be taking them off this winter

LMAO, this guy had longtubes also. So a little extra work for him.

Awesome, i am glad to see such healthy numbers, we are doing my buddies 2011 turbo kit shortly. He doesn't have the 76mm but still, it will do perfect for his power level.

Man that's sick. These motors really respond well to mods.

+1 ?

Its not really that the turbo is too big for the wastegate, its about flow. A 38-44mm gate is perfect for 5 liter 4v motor at that boost level. You are getting a little creep at 5500 but the jump at the end is odd, doubt that creep could do that. Easy test for back pressure/creep would be to disconnect the wg dump tube and vent to atmosphere do a pull and see what happens. for this kind of setup the wg is a little close to the turbo for my liking.

Does this kit keep cats, if so, before or after the turbo?

Also on a side note that dinky filter is very restrictive like that, especialy at full boost in the upper rpms, alot more than you think. With a system mounted like that behind/inside the bumper I would definetly remove that air filter.

Another question about this kit, does this setup with the lower mounted turbo come with a scavenging pump for the oil drain?

Well I will have to disgree. Especially since there is no real downside to a WG that is a little bigger than you need. But there is a big disadvantage to one that is smaller than you need.

I do agree with that and I'm leaning toward a back pressure/valve spring problem. Gate already dumps to atmosphere. I have the ability to log back pressure but we didn't have time that day. We will when we swap gates.

No cats

I think that would be very bad advice. First, the car is making more than enough power, so if the filter is a bit restrictive I think he would be more than happy to give up 20 hp in return for protecting his billet wheeled turbo.

Another question about this kit, does this setup with the lower mounted turbo come with a scavenging pump for the oil drain?

Yes, there would be no way to make it work without a pump.
