Completed Project Moving-On, No More Kenne Bell Supercharged 5.0

[Blown]

I suppose this thread has certainly run it's course over 4 years!

I think I am done, finally!

I noticed the IAT go from 140 to 160 at idle after I disconnected the bypass and I stabbed the throttle a couple of times. The IAT was recovering slowly, then I hooked-up the bypass and it quickly recovered, back down to 140.

 

[Blown]

It's never done
I couldn't find another pulley when I ordered a 3 11/16' pulley from Kenne Bell.
I found and have ordered a 3.5" pulley to get this thing where I want it. That should get about 7.6lbs of boost at 5,500' in elevation here around Denver and allow me to get the pulley on easier with the same belt length, it's been tight...................

Current Pulley Ratio 6.5/3 11/16 or 3.6875 = 175:1
Proposed pulley Ratio = 6.5/3.5 = 1.86:1
((14.7psi at Sea level+Boost) / 14.7) x (engine liters / 2)) / Supercharger Size liters = Theoretical Pulley Ratio
Current 3 11/16" pulley: ((12psi at 5,500'+6.6lbs)/12)X5/2))/2.2=1.76:1
Proposed 3 1/2" pulley: ((12psi at 5,500'+7.6lbs)/12)X5/2))/2.2=1.86:1

((13.2psi at 3,000'+8.4lbs)/12)X5/2))/2.2=1.86:1
((14.7psi at sea level'+9.7lbs)/12)X5/2))/2.2=1.86:1

What sizes of extra pulleys do you have now? Is there a good way to use any of the better looking pulleys on a KB? I've read their site talk of nothing but steel made by them being acceptable. I don't like the plain pulleys, not when so many others are great looking with multiple holes in them. I'm curious if you have looked into any of that?

I was looking for a basic pulley. However I have seen set-ups with a hub mounted to the blower and various quick change pulley's.

I sold the 2 3/4'. I have a 4", 3 3/8", 3 11/16" and will soon have the 3 1/2". The 4" was good to get it tuned, set-up, and I knew it needed more fuel pump for any more boost. The 3 3/8 is a bit much, would be too much boost when at lower altitude to keep cool and could overpower running gear.

These guy's are newer and need to get some pics up: Products - • Supercharger Drive Type - Kenne Bell - Z-Industries, Inc. Store

I ordered from here: Kenne Bell Supercharger Pulley

 

[CDW6212R]

Very good. I was also thinking of starting with a larger pulley in the 3.5-4" range, for using with the stock engine/pistons.

 

[Blown]

FYI - I ordered from TPS Motorsports and my pulley was drop shipped from Kenne Bell. Kenne Bell has pulleys and I should have ordered direct from them. FedEx screwed-up the shipment and delivered it to the wrong household! KB has sent another one out and is going to chase the missing one down. I should have it Friday, three F'ing weeks after I ordered it............................. It's not a huge gain but should be an about an additional 18 horses and 20flbs of torque!

I re-measured the big pulley I have and it is actually 4 3/16". It is old and likely came with the original kit for F150/Bronco with no Supercharger Bypass in an attempt to keep boost down and IAT temps lower.

I recently got an email from the guy I bought the kit from, he wanted it back.........................No way man.

 

[Blown]

Yes, More power is good without adding more fuel! I figure this thing is at 322.5 ponies and 420 torqs at the crank!

I am getting 13mpg around town if I stay-out of boost as much as I can. I want to check the highway mileage, it's always up a hill around here and in boost, so maybe 15-16mpg.

I think the boost gauge is reading a bit low or there may be a restriction in the airbox size. I am going to put a vacuum fitting on the air box and see what it reads under boost.

 

[CDW6212R]

For good boost levels, you need as large of inlet parts as possible. Try to make the TB and all parts before and after, much bigger, as in 50% bigger, or more. If the boost is 8psi for example, that's over 50% more airflow coming out of the blower, if and only if inlet parts flow over 50% more air. So the stock TB is 70mm, what's a 50% larger area size in diameter? That 90mm size is getting it close then.

finally! someone with a more realistic thinking of what kind of power they are making!

 

[Blown]

I have run the 3 3/8" blower pulley during the winter, about 8.5lbs. It was hard to keep out of boost and mileage went way down. It was in boost and open loop fuel for the slightest hill or 1/3 throttle.

I run a 90mm Lightning MAF into a 75mm throttle body. I don't think a larger throttle body would make a difference because of the smaller plenum that feeds into the blower at the back.

It's a good weekend to hang at home, Memorial Day travelers everywhere, and I should get s chance to check for vacuum at the filter box.

 

[Blown]

Oh no, She is sucking!

I got the vacuum gauge hooked to the air box and saw maybe 1/2lb of vacuum at full boost. That is not good. I want that 1/2lb as boost! I will be shopping the wrecking yard for a bigger air box for a Ford Truck and likely another drop-in K&N filter.......................

Upgrading injectors from single jet rebuilt units. I never have been able to find the calibration summary for them. I am getting Bosch Green Giants, originally found in the Lightning.

I am buying new and it should improve my tune a bit since the calibration of these injectors is well known.

Fords M-9593-F302 by Bosch part # 0280155968

[Advertised Flow Rate] X [The Square Root of (Your Pressure ÷ Rated Pressure)]

What is the output of a 43 lbs./hr. injector rated at 39.15 psi. if you run it at 64 psi.?

64 ÷ 39.5 = 1.635

√ 1.635 = 1.279

43 X 1.279 = 55.00lbs./hr.
46 X 1.279 = 58.83lbs./hr.

Ahhhhhhhh PooP! Sweating like mad today, a hot and humid one this morning! I installed new plugz, coils and wires this morning, runs great again! I saved three, not so old, wires for spares and the one good coil.

About a week ago, I was trying to track down a miss. I accidently pulled the damn spark plug clip right out of the wire on number 3. I did my best to pull the boot and re-attach the wire to the spark plug clip. It worked well, then started missing on Sunday. I think the coil was going and the plug wire hastened it's demise............................it rared it's ugly head and made the truck die a couple times trying to get home.

She got all stinky rich, had a consistent miss and I thought no spark or a stuck injector

I went with Motorcraft coils, some double platinum plugz, and AutoZone wires. Yes, Autozone has a good set of 8mm, high temp, very well heat shielded wires............................

The injectors are coming toady!

I got one squeaky alternator belt/pulley combo. It is a brass looking pulley and small to produce more revs and current. The next smaller belt is too small. I am going to have to get a bigger idler or move it so the belt is tighter. I drilled an tapped to place the stock idler on the supercharger snout mount. I think I can move the idler pulley down some to tighten up the belt.

 

[CDW6212R]

Installing a larger idler pulley is a good option. I did that with one of the alternators I've swapped to, I think it was my 99 SOHC and a DB Elect unit. That let me keep using a belt which I had just replaced. I try to save any old pulleys, they can come in handy later, even for testing.

May help

Thanks men!

OK, I had a spare idler pulley to swap-out to make-up the belt length removed by using a small alternator pulley I could just barely get the belt on. ............didn't work, still belt slippage at the alternator and I can't go anymore. It is better, but slips in the afternoon heat when I stomp it to the floor. I can't complain at how fast these 5.0's wind-up, but I need to fix the squeal.

I am thinking I need to see how much current my rig is using and then maybe put a larger alternator pulley on.......................

I got the new Green Giant Lightning injectors I ordered by Bosch. They came with seals on the boxes, proof they are genuine, and you can look them up online to be sure, no cheap Chinese knock-offs!! I will need to solder EV1 connectors back on when I install them.

[CDW6212R]

What size are your two main stock idler pulleys? I'd find a smaller idler pulley and install a bigger alternator pulley, to help to stop any belt slipping. I recall the big idler pulleys being close to 3", and are identical originally. One is the tensioner pulley, I'd try to leave that one as it is for the tensioner.
