SUPERCHARGED 5.0L FORD MODS 

When I was a kid our "family car" was an 83 Capri 5.0L..... it had basic mods everyone would do to Foxs later on.... 3.73s, long headers, 2.5 dual exhaust..... After Mom missed a gear (ROD 4spd) and kicked the rods out of the orginal 5.0L, Dad built a 306 with ported SVO J302 heads, Engle cam and topped it with a B&M 174 that had twin Mikuni side drafts.... He thoughtfully swapped the ROD for a C4 automatic and the early 7.5" rear broke first timehe launchedit at the track..... luckily the 8.8 rears were out by then and we got one under the car. That car was a legend in the ATL scene from the mid 1980s through out the early 1990s. Ran high 10s on slicks at Commerce a few times. That was unbelievably fast in those days. Nice video, thx for the trip down memory lane.

the little blowers make even a 302 get with the program....good job...

RICHARD, good to see you back, we missed you.

351w round TWO please!

He's ba-aaaak! Back in 89, I took my newly assembled 434 MC SS, a fairly mild street car, to a test & tune at the local strip. First thing they lined me up against, was a wicked sounding Fox body. Had a blower up through the hood, and slicks, to boot. I just naturally figured I was about to get stomped on, and thoroughly embarrassed the first time out. But that mild N/A 434 walked away from the Mustang like he was stuck in first gear. The race wasn't even close. Really made my day. There is just no substitute for cubes...

I had pretty much that same combo years ago in my 87 Mustang Notch. What a extremely fun car on the street and a 10.00 to 10.15 at the track. It did click off some high 9s to. But that combo is a simple straight forward build to make really good power. And at 2840 lbs like mine lots of fun and good mileage. Thanks for this test Richard for this test. I have told many guys to do this build and they just blew it off. So thanks for showing what it is capable of.

Thanks for taking your time to pull wrenches and share the combination results, it is priceless for us guys that don't have a dyno but a lot of ideas in the head that maybe are not so good or confirmed with your testings

Very impressed with the E7 supercharger numbers. Really thought the cam/heads swap would be more. I can imagine the 425 horsepower with stock HO cam and E7 heads would be a very reliable combo. It would make a street driven Fox a whole lot of fun with years and years of enjoyment

Always wondered how well these little Weiand blowers work. Good stuff!

I have one of these sc on a stock 68 302 cast time bomb. So far so good. I did add some electronics to help it for a little while. Thanks for the content Richard.

Yesterday I was thinking to myself that it’s been a while since you have posted a video, glad to see you’re back.

Richard , the king on content !

Hi Richard, thanks for answering, I never expected you would even read my note. I follow you because you have so much experience and knowledge on combinations. Best wishes Richard, Bill

Nice Build just imagine a 347...Thanks Richard‼

I've got a 302 with a B&M 144 with a 750 Holley Built the motor to mirror the sbc test motor that B&M did. This was back in the late 80's put in a model A. Never knew the HP but it was fun, Thanks for the video.

I'm a Ford guy it's cool to see a few more to a 5.0 thanks again

The first boost curve is hilarious. It looks like a centrifugal blower.

That made some decent power and torque! 👍👍

Great and informative video! 👍🏼👍🏼

Great upgrades!!!! Thanks for sharing!!!!

Just came across this great video! I have an old 302 Mustang Ive been wanting to put that exact 174 blower on for years. I wanted to build a HiPo 289 but the blower might be easier, cheaper, and more power.

He really get's a kick out of it, when it's time to say.....RUN MORE BOOST.....can barely hold back the big grin....good test.

I love you. This helps a lot. I’m in the middle of building a motor help me realize what package I should go with.

Heyyyoo! Happy Sunday to me with some 5.0L dyno testing as I rise from my slumber.

Fun batch of tests!

grew up driving around in my moms 85.5 Mustang GT. It had a cam, rear gear 3.73 (had 3.27 stock). My old man's best ET was 11.88 with cheater slicks and offroad xpipe with no cats just mufflers. Loving the content. My brain loves all these numbers and machines. Have a good day Rich!

Awesome video!

Love the 5.0 content

You should test the limits of that blower by stroking the engine, which for me would be a good test to see how HP that blower can supply. Nice videos love watching

I got to drive a Kenne Bell 2.2L non intercooled blowzilla sn95. That car made about 9#'s from 2-6k rpms and the torque never dropped off. Problem was it would not hook on the street despite having a 12 inch wide radial. So much fun out of a stock 5.0.

We need some dodge 3.8 Pentastar in the other guys series. They are almost free at the scrap yard and good for front and rear wheel drive projects.

Less boost and more power, Love it!!

Holley stopped making this 174-blower last year. Kind of sad as they are really nice and do add some power. I put one on a 351W using PMS adaptor plates, distributor adaptor, 750 carb and a longer belt, aluminum heads, stock grind roller cam. Works well but had to put on a 3-inch pully to get the boost up to 7 psi. When it wears out it will hit the scrap bin as there are no parts available for this blower. There is a new roots type blower with a water inner cooler in testing from Australia for the 302 that uses a serpentine belt setup with fuel injectors, 19 psi boost that makes a lot of power. Should be on the US market soon. But I don't know if it will fit a 351 W.

So cool that you made this video. I have a stock block scat 347 forged crank h-beam rod’s srp pistons 10.5 to 1 Afr 185s ,Comp cams xe282hr rpm air gap , Aed 750 carb with a tremec magnum 6 spd and 4.30s 31 spline axles in 85 notch. Was thinking about using this supercharger and staying with a carb so I can tune it myself but I heard bad things about drivability issues- tuning-heat. There’s not a lot of info out there on this setup.

Cool video. Im gonna order a smaller upper pulley for my 142 Weiand

Your budget boost tests are very informative and are helping me form a plan for a boosted Ford. I would really like to see e85 directly compared to common pump 92 octane e10.

Those blowers are nearly $4000 here in Canada. A good Nitrous setup is maybe $1000 with a bottle warmer.

This makes me want to duplicate this engine then buy a old Ford to put it in. Nicely done.

Again thanks for sharing...

Richard, you teased me with coyote big bang content. My mouth has been watering ever since. When is that content coming out?

Love this one..great info, yur technique is very good 👍 👌 👏 😀

Always concerned making a stock block 302 put out over 500hp, good job!

This is information I have pondered for over 16 years...

Nice one! Would love to see a small block mopar on your channel :)

I would love to see a turbocharged bike engine! Keep up the great content Richard.

Richard, I wish I knew you in 1967, I had a D dragster that had a Ford flathead(53 block) with Hillborn injection a crane R450 cam. It was very late in competitive flathead racing, but I had fun. Pump gas ! 10:98 @ 117 best time. I was off by ~ 0.8 seconds on the record, Pete Shadinger ~ 10.3 ! Did you ever do flatheads! I am in awe of your knowledge! Bill

Had a 98 GT 2v 4.6 with frpp/svo blower at 9-10lbs. Fun times.

Going to find me a setup soon. Only issue with this video is that I wanted to hear it WHINE

Love it all! but I'm waiting patiently for an FE ford motor to sneak in there? With boost of course!

Sure be nice to see that big bang big block...

Would be curious to have seen the 8lbs of boost with a similar cam but with 115 LSA, Liked the video : )

Thanks Richard... I have an 87 Lincoln Mark 7 and I planned to boost it potentially turbo.. your recent vids have helped me see right where I need to look. Keep the vids coming 😉

I put 5.0 Gt40p heads that were ported from the machine shop when they enlarged the head bolt holes on a bored 10of over 5.8 with dual plane Weiland stealth and 1:7 roller rockers 650 holley vac secondaries and a mild comp cams extreme 4x4 cam for low to mid range power for my 91 interceptor but never got to put it in as the car got destroyed on the trailer when it got a flat. Been sittin on the stand for over 10 years now always wondered what it would have made.

Hey Richard, put a 150 shot on top of that mini blower. It REALLY makes it sing and I used to run a 144 on a SBC that way.

I really wanna see some nitrous sbf stuff that would be awesome!

Just shy of 9 pounds of boost abd getting that little stock 302 to 435 horse is impressive

Good information thank you. Was pump gas used in the test and what was timing at. Thank you for another Ford test.

A new test that many of us would like to see on similar combinations would be the addition of snow ❄️ performance injection. Just to see a pump gas boost motor at max timing with this injection set up. This will allow max timing because it is equivalent to 116 octane. No intercooler or really an after cooler for a roots style. This is a liquid intercooler with the addition of high octane and no more hood clearance needed. Also you can do another addition to that combo for us street stealth people. That would be your favorite power adder and spray it with another 100 shot. Now that would be Super Man quality testing levels. This is for people who can never get enough !!!! Like me !!!!!

Put it right into block-splitting territory!

Right on

Super good

You are awesome! Love to hear your opinion on EFI cam vs. CARB cam? What, if any differences when running both on a carb engine, THANKS for all the info.

Nice fun safe combo. Above 700hp and the block spilts in half. LS engines power capability and durability has us all spoiled now.

I plan to do a 5.0L swap in my '99 Ranger soon (5.0 from a '98 Explorer) & thought about doing a supercharger build on it & hopefully make a whining noise but don't want to make a fuck ton of power, maybe at least 400hp max so idk what psi would I need for that much HP unless I should leave it N/A (only want to do cam, forged internals, headers, muffler, intake, NGK iridium plugs, porting, & a tune if I stay N/A, maybe have it tuned on 88 octane & E85 for racing on the track or "Mexico"

Heads and cam make sense on a roller 5.0. You can't get the lifters out with the heads on. You can do it on an engine stand if you flip the engine upside down but it's a nuance.

I wish Holley/Weiand, Eaton, TBS, and any other Roots blower builders would switch to the more efficient Twin Screw design. But I suppose the price would skyrocket.

Even though I'm more of a Mopar guy (the pic is my wife), this build makes me wish I still had my 66 Falcon, or my 78 Mustang II Mach One, or one of my 4 Mavericks.

Richard good to see you back again. I love the look mini charger on a small block. I really Hope speedmaster makes a intake for it to fit the LS. So far They Only make it for the 671&871.

Just got a 302 always been curious what you can do with them.

Richard you do the best 5.0 litre ford strokers keep up with the great work how about a 302 boss full spec rebuild 347 stroke Windsor bottom end with Cleveland heads and manifold just want to see the power it makes

Richard is it in your plans in the future to test cylinder fuel distribution problems with a single plane intake, on a ford engine which have equally spaced intake runners, and test either exhaust temperature or O2 % on each cylinder and see if by changing to higher rocker arm ratios on those leaner cylinders will help to get them closer to all other cylinders and see what results will that bring on the dyno, if there is a SBF available with enough valve to piston clearance and far away from spring coil bind, I guess it is a relatively cheap and fast test, because it is only changing rocker arms and pushrods, and some welding to old headers to install either the RTD's or O2 sensors that are already available at the dyno shop if it is not already available, don't forget the 4 hole spacer 1.5" tall for the single plane intake. Regards

You need to turn up the boost until you increase the bank angle beyond 90 degrees. This will lower your center of gravity.

I want to put a supercharger on my 89 towncar. I’m a dirtbike guy so this will be a learning experience

Richard As always : great vid and reliable information that we can use. Now, ( on the oddball engine subject ), how about the 3.8 Ford Supercoupe? Had one years ago. With a pulley change and exhaust, it really ran good. Would like to see a build. I'm thinking about one for an engine swap. I remember it as a really complex system. Is it worth the trouble ?

great vid. add E85 carb , E85, turn up the boost and see what happens.

Add boost till the block splits then back off a few psi. :-)

I am always looking for that supercharger slapped on a bone stock smog era engine. The few I’ve seen were absolute burnout machines but no dyno numbers. Can you throw on on a 305 Chevy or even a 301 Pontiac?

Do you have any IAT testing with a draw through like this? I'd be interested to see how much the charge cooling brings temps down, especially with pump e85 : )

Really highlights how good an LS 4.8 is

Surprised that block survived....I've seen them slit down the middle at those power levels

Nice little small block set /package //. I looking forward to going to states to try out selves new block with there supercharged set up on the track .: I going home this year ///. Want to get some track time in this year ,. I stay in touch let you know how I get on @marcus

How about results from a stock 5.0l more boost with intercooler maybe with cam? Rather not hurt the more expensive heads if possible.

Thanks Richard. Damn that little 302 is so underestimated as stock with a minor upgrades like flat top pistons. Without the blower would we see like 210-225hp?? Thanks Richard

How far forward does that 174 protrude? Trying to measure one up for my engine bay but the Holley docs are for a 177

How do the E7TE heads compare to the GT40P (Explorer) heads, which are still available in boneyards?

Can you put together a video showing the dollar per horse power comparison between all these motors you have been testing.

Been awhile, you had us spoiled wuth releasing a video almost daily! Quick question rich, does anyone make a top mount blower like this for the 351W? Theres a market for it! LS type top mount on a stroker Windsor would be nasty!!

Richard. I have a question. 1971 Ford 302 Mexican block out of a mustang. Unknown mileage. I’m running Holley sniper efi and ignition. With edelbrock performer 289 intake with one inch open spacer. Runs great. Haven’t put it on the rolling road with the Holley yet. I do have the edelbrock estreet heads and cam to go with it but haven’t installed them yet. I was thinking about introducing boost but I don’t want to add ring gap. Is this a bad decision? It’s in a 76 f100 with a three speed top loader and ford 9” rear 🤷🏽‍♂️ Help!!!

another good test video, can you do the same with a turbo?

The problem with running a supercharger with a carburetor on top and an intercooler underneath the supercharger is once the fuel Falls through the supercharger and hits the intercooler like say a water to water or a standard intercooler what will end up happening is it will freeze the fuel and cause an AIR block

Thanks for the continual great content. Are you able to share the ignition timing information. Base timing, how much timing you removed per pound of boost, etc. I have a similar set up and find my set up likes 22 initial, i am removing 3deg per pound of boost. Its a very conservative tune , looking to improve it soon. Any info is much appreciated..

that blower is considered too radical for a 350 chevy but just right for a 5.0 ford. I have been considering getting a 177 for a 350 for a long time. Some good heads like a 200 cc head and rolller cam should be rockin. And you can always slow the blower down to keep boost in line with fuel used. E-85 anyone?

Wonder what it would make with a 347 stroker set up ?

Richard Holdener When you say it has stock compression, a Google search says from 79-93, compression varied from 8.2 to 9.2. Where do you think this combo ended up? I'm trying to get an idea where my combo might end up based on your results.

I would like to see if Anderson power pipes actually increase boost and power on the same pulley.

Man this would be perfect for my play truck but I just checked there website and it says not available

Buenas tardes Saludos quisiera colocar super cargador a un Ford 302 puedo conservar poleas y carburador tiene algún número de parte gracias

Could you do a cam test, maybe hipo 289, vs fox ho, vs explorer, vs 351 Mach 1, vs your favorite comp cams, vs MY Lunati 51017 cam .536/.536 218/228 112lsa. Vs Anderson Something. Just a BIG 302/5.0 cam shoot out. With stock heads, then maybe cast aluminum, then cnc ported. Idk just an idea.

Richard holdener is this supcharger ok for a daily I just rebuilt my 302 but it has a f 303 cam and trick flow upper kit heads cam intake 24lb injectors

How well would all this fit under the hood? Need a 4" Cowl or what?
