who's running a "built" motor?

[RyanDS650X]

Have you had it on the dyno? If so what were the numbers? We have similar builds, mine made 211hp 289ft lbs. At the wheels

No, I'm scared that the dyno will disprove the amount of power I've calculated it makes. Ignorance is bliss!

Haha i know that feeling, i was hoping for more aswell. What does you math say?

400 or so, at the crank. The base motor was rated at 340 hp, and the mods are supposed to add the other 60. The biggest variable that is an unknown to me is how the Edelbrock Truck intake and dual bore throttle body affect the power compared to a traditional high performance intake manifold and large single bore throttle body (I know it's likely a peak power reducer, but by how much?). I do know that my motor is really 'peaky' - it's pretty good up to 2,800 rpms or so (feels like a 280 hp motor), and then it just RIPS.

sydude and Ryan.......ether of you port match intake to heads?

I think Ryan you have edelbrock heads so my not be needed.....the GT40 head my not need it ether at that matter...

I have same / similar motor build in the works..... Too both of you.

Thanks

Not running build motor yet and this is a who running a “built” motor thread so I apologize if I should have held off until motor is in the bronco….. But I love taking about Horsepower.

Note to all………transmission shift points will help your motor and use all or most of the power band if set up correctly with the E40D (if you’re a C6 manual Valve body with shifter you’re doing it yourself). Not an expert on motor and tranny ……just have a toy (Usshift) that I can change things on the trans and it has made my stock motor with headers come alive. As much as improving the motor HP and TQ is a must making sure you put that power to good use though the drive train is just as important or you just have a built motor that sounds good …….hah
Lots of ways to do this and my 2 cents and the Usshift is just one…….
Now back to Motor

Seabass has been great with feedback as we have talked a little about 460 swap in the bronco vs built 351w a little while back.

Most do not like the supercharger option on these desert trucks ....but I plan on keeping the motor build simple and then add my Paxton with a low lb. pulley for more pop above the 3000 rpm range.
Thought would be balance low-end and high-end HP TQ with complementing parts........for sure just a theory at this point though……..Other than the street bronco I had with a Central Coast Mustang High Performance Engine and a vortech supercharger on it with a 5lb pulley back in 2003. Ya I know 10 years back. Info on motor

I got the idea ( or came back to the idea) from a buddy that has a 2x 1995 f150 prerunner with all the bells and whistles with a 302 built like sydude and a vortech supercharger he has been running this set up hard for about 6 years no issue so far…….for sure this moves the truck well with 37 inch tires dual spares and 80 gal fuel tank full gear ( not sure of the weight of the truck but it not skinny)

I do have the edelbrock head and intake so im good there. Willy and I breifly discussed throttle tip in with a larger TB and the possible issues with it on the bottom end. Has anyone with a larger tb had low end issues?

[ChiroMatt]

So, one could run 80lbs injectors, high flow fuel pump, with high flow intake and exhaust, dyno tuned(sct, moates, tweaked etc) and change e40d shift points and WOT settings, with no other mods and get how much HP increase?

[cs_drums]

80lb!?! Stock is 19, the biggest I've heard of is 42 and that's on fire breathing strikers. I am planning to do what you stated above with the addition of gt40 heads, custom ground SD cam and probably the 460 injectors mentioned earlier. If I can get +300tq at the rear I'll be stoked.

[ChiroMatt]

Bosch 80lbs deka injectors. About $500

The turbo and supercharger 351w utilize these.

I'm sure any injector above stock is good, but with there r no limits?!

The ford engine guy what do u know about these?

Are they CNC port matching the intakes now? I had to do mine, it was way small, about factory port size. Must also match the TB to the intake if your running the big BBK unit.

Switching from the stock TB to the BBK unit didn't really make a noticeable difference to the low RPM power. Midrange yes. Top end not so much as I think the UMP was the limiting factor...........

[LvSteve]

The 80psi injectors are a preferred by may tuners, or dual 40psi aka gt40 or super snakes with a sin city kit

Most tuners will use 80psi injector with hi psi fuel system , A wide pulse with a power additive , turbo,super charger with 12psi boast or higher or a 150 shoot

For our use on a 5000 lbs unit , uncontrolled fuels aka pump gas the 42psi will take you to 600 hp on the crank or more . if your fuel system keeps up

The eco boast lost a ring land , rolled the piston crown up and galled the cylinder , PUMP GAS

The new 5.0 cam for the 15 Mustang track pack with vct is a short duration with hi lift tune, I need this in my fine , better call Comp

[LvSteve]

I think we need a motor , tune and thread

[ChiroMatt]

Tcinu2

Yes we need a motor section.

How to build in progressive stages for most bang for ur buck

What can be done externally with out tearing
into the engine?

What r the preferred programming methods?
SCT, Moates qtr horse, Tweaker etc?

Exhausts? Manifolds? Intakes? Etc

Thx for ur help

So in our race bronco we are running a 351w roller with a stock bottom block out of 1997 f250.
It has Edlebrock heads perform rpm 2.02, edlebrock upper and lower intake, Edelbrock 1.6 roller rockers (we got a discount sponsorship from Edelbrock), COMP Cams camshaft 35-312-8 - Duration 276/280, Lift .544/.560, f159 lightning 90mm Mafs, 75mm throttle body, 42lbs injectors, 1 5/8" primary tube full length headers, 3" dual exhaust, aftermarket fuel rail from summit, 1991 mustang 5.0 wiring harness and computer (automatic car), tweecer tuner (they tuned it). Not sure on the horsepower but it's in the 400 range and it has tons of torque. Will spin the 35 inch tires on the street no problem with 4.56 gears. It has plenty of torque and is very responsive. The truck is has twice the power it had with the stock 351w. It's so much fun to drive. It has no problem in sand anymore 80 mph in deep sand is not a problem.

What filter set up are you using? I know if your 400-500 hp it will require one large filter or 2. With shock hoops and engine cage it kills the space in there. I am in the middle of trying to find something small enough to fit to handle that hp range.

I had plenty of space, so I put in a comically large K&N filter in. I'll try and snap a shot of it for you when I get home.

[sydude]

Here you go. Comically large air filter.
