Just picked up a new truck magazine and discovered Magnacharger is coming out with an intercooled S/C for Chuby's. It is supposed to have up to 7 PSI boost with no detonation problems or ignition retard. I went to their site and I didn't see anything new for us Ford guys. They put it on a 4.8 liter and picked up over a 100 H.P. and well over 100 lb.-ft. of torque. I was wondering if Crash had any more information or knew anything about the availability for Fords?

The current Allen (formerly Magna) supercharger kits for our Fords are already intercooled. No pre-detonation problems if you stick with stock boost and stock set-up. NOW we know that, if you increase boost or other mods, you MAY need a cooler thermostat, just like other kits and or increase capacity of the intercooler system.

NOW, I am running the "Bazooka" 12 pound boost pulley on my 99' F-150 4.6, WITH NO pre-detonation problems, SINCE I just installed a 170 degree thermostat. A dyno tune SHOULD correct my hesitation problems under high rpms and high speed.

Another good question would be........when is Allen or Magna going to offer a Ford kit that utilizes the M112 Eaton blower (the chevy kit uses the M112) as opposed to the current M90?

Or more important for many of us, when is someone going to develop an intake manifold OR adapter kit to allow current Ford Allen (Magna) Kit users to utilize the M112 OR Whipple?

 

Sheesh, where have I been? For some reason, I thought the ATI was the only intercooled kit for our trucks. I didn't realize we could run that much boost pressure without any significant problems. I guess I need to start reading without moving my lips or something. I was completely oblivious to the intercooler thing. Thanks Iron Horse.

You can get an "air to air" intercooler with the ATI. The ATI centrifugal unit has much cooler discharge temps.

The Allen (Magna) kits ALL come with a "liquid to air" intercooler system composed of the intercooler in the Kit equiped upper intake manifold as well as a intercooler heat exchanger (looks like a trans. cooler), an electric pump, and a heat exchanger tank (holds about 20% of a gallon and has a radiator cap). All of this is connected by hoses as well.

Currently, I have also included a oem lightning heat exchanger (looks like a mini-radiator) "in-series" with the rest of the system (can get it VERY cheap from JDM). I am currently waiting on a custom heat exchanger tank, that holds over a gallon of liquid.

 

Iron Horse, what kind of dyno numbers are you getting out of your Allen/Magnacharger? I was really impressed with Crashes 360+ H.P. with his 4.6 and the ATI. I had been considering the P.I. headswap, but JMC's thread in the computer chip forum has me wondering if I want to worry about the logistics of raising the compression ratio, cams, etc, and keeping normally aspirated is not a big deal for me. I may be wrong, but it seems that a S/C install would net more ponies with less hassle. Did you have to make any other mods for the Allen(Injectors, fuel pump)? I have a set of The Other Guys medium length headers on the way to replace the Pacesetters.

Good Question! I have no dyno runs......yet! When I go for the dyno tuning of the chip, I will know my numbers. I am hoping for 300 rear wheel hp and 350 to 400 tq.

Yeah, the "Powerbrakers" numbers were very impressive. He basicaly produced the hp/torque of a 99-2000 Lightning with a F-150 4.6! Remember, the ATI itself is good for an additional 20 hp or so, over the Allen (Magna). PI heads (2001-up 4.6 & 1999 -up 5.4) are good for 10-20 more hp over non-PI heads. You also "lose" less rear wheel hp with a standard trans.

JMC is very knowledgeable of our trucks. I think a major concern that we all have about that swap is "matching" the non-PI piston to the PI head. I would think, without a supercharger, the cast enternals can handle it. I am watching that thread very closely.

It seems a supercharger install would be easier to do. If you look for a used supercharger kit, I know it would also be about the same cost. Of course, I want both! ha! But, I would also have to have a forged internal block.

 

Just for reference sake, I have the Magna installed on my 4.6 4x4. I also insalled the 9# pulley. My dyno #'s were 279h.p, 322 ft/lbs of torque. Now this was with a chip that wasn't tuned in exactly right. You can expect better numbers when everything is dialed in properly.

 

Iron horse, Raycee,
Just out of curiousity, any idea(guess) how much horsepower you picked up with the Allen/Magna's? I have been telling myself 300 H.P. to the pavement would be great, but Crash has given me horsepower envy. Now I find myself trying to figure out how to get 350+ to the rear wheels with the stock internals. Besides the Dodge Hemi coming out in their half tons kind of pisses me off.lol
Rick

 

......as you know 350 to 370 hp at the rear wheels is all that the 4.6 cast internal engine, can handle.....safely. I am certain that the bazooka 12 pound boost pulley on my Allen (Magna) with some ported and polished heads would get me there, but I am going to wait to see what my correctly tuned dyno numbers are first and..........pay off all these mods!!!!!!!!! ha!

 

how long did the engine last with that power level and tune? the new engine he has should take it but i dont think it was cheap and next will be the trans and rear end.

 

Good points all. I have been looking around the Houston area for a seasoned block, but even a used engine looks like it will consume most of what I have saved for a blower. I may have to look into one of those "covert" credit cards I keep reading about. lol. I guess maybe the best thing to do would be to give Crash a call and get some help narrowing down my options,or at least trying keep myself realistic about this. I don't have a third vehicle right now, so I can't afford to be down with a blown engine either. Thanks for the input guys.
Rick

 

........actually, brotherdaves comments remind me that, I always thought that if the 4.6 can handle 400 at the crank, and you lost 65 hp due to the auto trans., that would equate to 335 hp at the rear wheels as the max. "safe" amount for the stock cast internal 4.6. Based on that, I should already be near the "safe" limit

 

lilricky2 - dont get ahead of yourself. why not get a basic kit first, belief me its a big upgrade over stock and most come ready to go with either a chip or somthing to work with the computer. you will also need to do a shift kit at the same time. enjoy it and take it to the track a few times to see jujst where you are at and make sure you have that combination running the best it can.

then go for either electric fans, rear gears and exhaust work, if you still arent there then go towards the injector, mass airflow, custom chip and pulley thing and start putting away money for a built engine.

 

I think that Ray C's numbers are what most of us can expect. If you remember that's around what Flats Man was getting with the 9 and a bunch of other mods.

Believe me, I would like to say that we will be getting more. I am running the 9 now and would like to think that I've reached 300rwhp. I'm not going to get my hopes up thought. I think my only advantage (and only on the dyno) would be the manual transmission.

The M90 and the non-PI 4.6 seem to have limitations.

 

Wittom, if you had the opportunity, would you stay with the Allen or go with the ATI? Brotherdave, I have a manual tranny behind my 4.6. I have a set of Gibson headers and a superchip. Will I need to send my chip back to Mike Troyer? I am probably worrying a little prematurely about some of this since I only have about half the cash saved up at this point. I am tempted to go ahead and take the plunge with Mister Visa or Mister Mastercard. This is why the P.I. heads look so appealing, I have enough $$$ to get a set off e-bay and get them reworked right now. Sheesh, the more I look into this the more confused I get. Of course my wife thinks I'm a pretty confused individual anyway.lol. Well, I'm off to continue sorting through the madness.
