Vortech supercharged 460 help needed

Unread postby Big Boss Pushkin » Mon Jan 07, 2019 1:08 pm

I have a 79 f150. The current 460 engine is a 1993 thats converted to mass air A9P with a quarterhorse. 24lb injectors and 80 mm mass air. It was running great till water got in and filled up the whole damn gas tank.

I ordered a polyethylene gas tank and we'll be cleaning out the whole system. I'm running 3/8" lines supply and return. Pump is a 340 lph aeromotive stealth. The tank will be a 1996 f250 replacement.

So once I get this back to running good again I plan to install the kinda rare vortech supercharger.

Where I need help is should I ditch the FMU and go with bigger injectors? It seems like more crap to fail or a bandaid.

Also what injectors Should I get? Ford green 42lb? Seimens deka 60lb? What will be a good overkill choice? And have all the info I need for the binary Editor software.

I have the vortech BTM (MSD unit) and a MSD 6AL box to wire up. Unless there is no reason to use a BTM?

It's been a couple years since I've done any of the tuning stuff so I've forgotten a lot please excuse me.

welcome to the forum dave

I always liked those older trucks I always make sure I stop by when I see them at car shows, if for nothing else they all usually have pretty interesting stories

if u got water through the lines then it would be best to yank the injectors and rails / lines out along with the regulator and back flush all that as well. I recommend using acetone to clean it all out as it works decent.

yea I would ditch the 24s and toss in some siemens deka 80s from chris at poweraddersolutions. Tell him decipha @ EFI Dyno Tuning referred you and he will take good care of you.

the info for the injectors are on the homepage under references >> injector data

nope dont need the btm the 6al is fine, the ecu sees boost as load so you control timing in boost in the spark table same as u would otherwise

it will all come back to you in no time

btw, I maintain all the free DIY tuning support for TunerPro along with my own modified A9L2 and GUFX strategy all available on the homepage as free downloads. I'm partial to my own stuff as is most people that do development but its undeniable I have ALOT more features in my own stuff than anyone else.

Thank you I appreciate the help! I started with your A9L2 strategy and only made a few tweaks to get running.

The truck was my grandpa's since new. It's no show queen since it had 505K miles before the original 460 blew 3 rods at once. It only had 2 head jobs on the original engine as well. It's a 1979 F150 XLT Ranger Trailer special. As much as I'd like to repaint it to the original color I will likely leave it as my grandpa had it. Those 505k miles were rough miles everyone drove it hard. It still had the original oem C6 transmission after the engine blew. The only thing that hurt it was a crappy starter broke and ended up cracking the case in the bell housing area....

About 11 years ago I put the EFI 460 in running off of a stock A9P EEC. It basically was a reliable turd that could only do about 75 mph before leaning out. Then in 2015 or 2016 I bought the moates quarterhorse and binary Editor software with the dongle and a innovate DLG-1 dual wideband.

I was discouraged a few months ago when I figured I had fuel issues. It's sat since then. Now that I found the vortech supercharger I couldn't wait to get the engine running great first then install the supercharger. I was literally looking for a ranch hand bumper for my f250 on Facebook marketplace then I stumbled on a whole entire supercharger set up off of a low mileage truck at a very cheap price. I couldn't believe it.

Thanks again for the help! I will buy those injectors in about a week. I'm curious what kind of power it will make. Last time I had it out I whopped a 96 cobra or at least it looked like one lol. Granted I treed his ass but I was amazed he couldn't catch up and pass me.

I ordered the 80 lb injectors from PAS. I Used the injector info from one of your pages and it idles perfectly and is making great power! I really wasn't expecting it to slam me back and bolt off burning both tires! (Open 9" rear 3.70 gears)

Now I need to get this truck legal again...

Couple questions, after I dial it in for naturally aspirated I plan to bolt on the vortech supercharger. What should my timing table look like to start off?

Also do I still run a stock spark plug or which one do you suggest?

best to toss a heat ranger colder plug in it with the blower

easiest and safest way to setup timing for now assuming u dialed in the spark table it to just command half of your wot n/a spark when in boost

so lets assume you dialed in your peak load for fn035 and at 3000 rpm lets say for example you reach a peak load of 0.65

if you are running 87 octane lets assume you have 26 degrees of timing in your spark table at .65 load @ 3000 rpm. Simply go command half of that at half of the load more. So 26/2 == 13 degrees of timing. 0.65/2 == 0.32; thus 0.65+0.32== 0.97 load

at 3000 rpm and 0.97 load command 13 degrees of timing. Interpolate the spark values to fit your load cells.

calculate that for each rpm column and adjust the entire table. Now keep in mind your n/a spark values dont need any adjustment so below 0.65 load at 3k rpm in the example above u dont need to mess with since u already dialed it in.

In any case this is just to get it started and going safely u will still need to dial in your spark table.

You will see in the a9l2 tune the spark table is already similarly done.

Thanks for all the help! I went ahead and just purchased the tuner pro RT.

Since I'm using that a9l2 bin and I read about other people running into issues with using that with BE.

I've been using BE I have a dongle version.

Getting closer now. I'm getting a little over 8 lbs of boost after 5500 rpm. It is a total different animal now with the vortech! Never thought a stock junkyard 460 could run so good. Before this engine would have trouble above 4600 RPM. Now looking at my log I hit over 5,800 kinda easily...

I'm thinking a 5600 RPM limit and shift at 5500 would be safer. I'm not mistaken I can do with RPM limiter in the tune? Or should I just get the correct pill for the a9l box?

yea I made significant changes to the a9l2 tune and it no longer follows the gufb strat that BE has thus tunerpro and the GUFX xdf

thats a big ol heavy rotating assembly in there no need to spin it high at 8lbs it should make plenty torque down low to get you going

If its a jy engine I wouldn't stress it too hard. Keep the Rs around 4800-5200

the engine would be safer with more boost and less rpm if u want to pulley it to get more lower

i think u meant pill for the 6al box? You can if youd like but you can do the same limiter with the ecu. Set the mnpip8 rev limiter in your tune to the RPM you want.

Ideally u dont want to bang the limiter you want to shift just before it
