Redemption Dyno!! 393ci Windsor Stroker | 1988 Fox Body Mustang Dyno (Part 2)

[@ogsuperflygarage]

Great work as usual guys!!

[@wolfthornhawkridge5705]

Never stop looking for the cause.

[@droppedf100]

Love seeing updates with real world issues and repairs 💪

[@mike4fo]

I love that you guys came back to the car to figure things out. Nice build

[@gregbartos9275]

Love it. Yup, that's working on cars for yah! Takes more confidence to say, "yup, I messed up/overlooked something", but what matters is looking into it and figuring out what the true root cause was. Finding the root cause is very rewarding! Especially when, in this case, it means a significant horsepower increase!

[@albertespinoza5842]

Good catch, that's what it's all about,gotta grind before you shine.

[@Nondescript15]

That’s amazing. Good catch.

[@Bacongrease00]

Custom camshaft and a ported intake manifold would pick up some power if the owner wanted to squeeze out even more. I think 450-460whp is on the table if optimized.

[@kennethbrown5784]

It definitely has more in it

[@Bacongrease00]

@ trick flow R lower is probably choking it down a bit. If I recall it flows like 260-275cfm stock form. A bit less than those heads can do. A super victor with an elbow would probably hurt the bottom end a bit but then after 4500 really start to wake up.

[@genemounce8302]

Merry Christmas from down here in Bertram, TX yall !

[@paulhudgins5120]

Awesome catch, like you said problems are linked to everyone who works on cars. Always trust the butt dyno.

[@lwellsfoxbody6491]

Awesome Find!🔥🔥

[@ClickbaitMotorsports]

Good info. Such a beautiful Fox, oh man. 🔥

[@MrCt302]

Oh Yea!!!!! 👍👍 Still got room for more..

[@awee5816]

Can a C4 trans handle this power without having any problems? Or are you going to fix it Now & then with the 393 ci.?

[@Olds_Pwr]

I say yes. Broader Performance seems to be very knowledgeable on these transmissions, may want to watch some of his videos.

[@awee5816]

@Olds_Pwr thanks 👍 bud

[@Hot_Rod_lincoln]

Wow good find! Merry Christmas guys and Landan you guys need to do a dyno video of the new sve heads on a stock(ish) motor and maybe do a comparison to gt40s

[@brianwdodge1]

Better! She’s still peaking at a very low RPM (5,300) though. Needs a shorter runner intake. If the peak was close to 6 grand she’d make way more power!

[@TexasMarkVII]

Correct me if I'm wrong, but should a Mass Air setup NOT have an open filter on the oil fill? Is that not unmetered air?

[@FourTwentySeven-f7m]

It can if the pcv hole is sealed up, vacuum line capped and the sample tube is capped off. Then it’s just venting to atmosphere. Should have a breather on both sides to keep It equal. Good catch btw

[@devengudinas1649]

Power

[@93_LXcpe]

Max. HP rpm seems a bit low, cam related?

[@KingJT80]

max HP at 5500+ RPM everything doesnt need to make 600 at the wheels. its NA which is good with that size cam and intake and heads

[@93_LXcpe]

@@KingJT80 423 @ 5300 just seems a touch low rpm wise, nothing wrong with it. I would take it 🙂

[@FourTwentySeven-f7m]

I believed they stopped the run there.

[@bradnimbus4836]

Fuel tank problem caused by the same guy?

[@MrCobracoupe]

What’s the rear tire size on drag radials?

[@whitetailfox1]

Would love to see this with a vortech supercharger bigger fuel system coil near plug swap and a box r manifold

[@kennethbrown5784]

I had a sump break anytime I got to lower than 1/2 tank it would die in a turn I just lived with it till the s hose busted

[@FourTwentySeven-f7m]

How many people said it was the pro m EFI system? Wrong as usual.

[@hereinmissoula11]

not sure if it is the cam timing or the intake, but this motor is choked. should not peak and then fall off like that... not at 5500

[@catchk9]

Share the combination because better numbers can be made with a 347

[@FourTwentySeven-f7m]

You show me a video of an na 347 putting those numbers down with off the shelf components and a box stock tune.

[@melissaregenwether]

car would benefit greatly from a box r upper. theres a huge casting flaw in the long runner r upper that slows airspeed

[@FourTwentySeven-f7m]

Maybe but need a different hood and torque would suffer.

[@anthonygrebner]

​@@FourTwentySeven-f7m Oh, got ya. So what you're saying is a decrease in horsepower to increase torque is a 21st century secret to going fast. We've all been missing out.

[@FourTwentySeven-f7m]

@@anthonygrebner depends if you want the engine to live at 5500+ guy. A decrease in torque is a decrease in hp. Simple math. What supposed flaw is in the long runner intake?
