How much boost in the stock setup?

[GSX-PKV]

Just wondering, in our Explorer Sport there is no boost gauge.  I wonder how much boost is run at wide open throttle?  Thanks.

about 12psi is max for stock.

about 12psi is max for stock.

Is that the same for the SHO?

 

[crash712us]

yep.

what is the max the stock turbos are capable of ? just wondering with other fuel support mods what their limits would be.

 

[goblues38]

"capable" ... i think I have seen 19+ psi some place on this board.

16ish psi is target "safe" range.

But I am a noob.  Someone will correct me.  I hope.

 

[crash712us]

Your right about 15-16psi is about maximum usable boost. They can produce more, but it's not efficient boost.

So upgraded fuel mods would basically be useless on stock turbos ?

No. Running E85 would allow more timing which is not available with the stock system.

More like upgraded fuel mods would be more than stock internals can handle.

I don't think this true at all. People have used meth, nitrous and supplementary fueling to the tune of 600awhp without the internals failing. Ford Racing is even using stock internals on their 3.5L Ecoboost race engine

 

[crash712us]

Ford racing uses a stock block That's it, there is only one person to claim 600hp and it was disassembled and sold in a soon after. So if that's proof enough for that's great.

But aren't you running upgraded fuel mods?

If you are interetsed in this on an ongoing basis, like I am, you might want to check out the Aeroforce Interceptor thread on here. Nice easy plug and play boost gauge. Sold in the store here too.

I am. But what i am trying to say is the car has enough fuel to over come the internals. Which is not true, but when comes to injectors and hpfp I would imagine will run into to thousands of dollars. Or meth for 1k just make 50-80hp. Everything goes hand and hand and one thing leads to another. It's just my opinion that a modified fuel system on a stock motor would be a waist of money.  But even even you did mod fuel system to handle more fuel the stock turbos won't keep up. So by doing these thing I am sure everyone will want the most potential out of them.

I'm going to disagree with this.

I'm seeing timing advance of 26 degrees at WOT in 1st gear.

I am also running 4/10 ths quicker on the corn.

13.70 @ 102.70
VS
13.31 @ 105.26

Torque indicated a peak increase of about 40 HP.

Seems to line up pretty well with my before and after times.

Thanks!  I bought my 87 Turbo Regal new and the first thing I did was put in a good boost gauge.  I run 21 lbs psi boost on the street on 93 octane gas with that car now.

You didn't like the Video game light bar boost gauge in the Regal?

Mine is worse than that. It has a digital dash with an 85 mph speedometer and just a red light that lights up when the car is in boost. 

The new Explorer Sport reminds me a lot of when I bought the Regal new. I was going to leave it stock and now 27 years later it has ported aluminum heads, a bigger turbo, injectors and intercooler, a roller cam, a built balanced and blueprinted motor and a methanol injection system. There is no cure for a need for speed

Your still on a stock tune? I am guessing that once you up the boost, your going to run out of fuel real quick.

That's where a upgrade fuel pump would benefit significantly being able to run E85 with a tune.
