After months of you guys pushing me, rubbing it in my face, and telling me how much I needed it, I finally got the Maggie. There goes my bike money....
It should be here Wednesday, and I plan on starting right away. In fact, I'm gonna do a few things ahead of time.
At least two of us jumped on this deal, so don't be shy if I missed a question.
1. Any tips, tricks, or things I need to look out for while doing the install? It seems like an easy job, but with your help, it'll be like I've done it before.
2. Do I really need to take off the nose?
3. Five gallons of coolant enough?
4. Let's talk about the Magnavolt. I know they were a problem, but haven't heard anything in the year I've owned my V. Problem solved?
I'll take extra care while grounding it. If it dies, will the car run at all? DON'T wanna get towed.
That said, I think Randy has bigger injectors, with no Magnavolt. Is it worth doing this, down the road, along with the Magnavolt?
5. Any spares I should buy (hoses, clamps,,,)?

???? Thought I'd have more questions.
Thanks guys

Tony

Tony-

I'm jealous that you're starting Wednesday. I still need my car to drive until Friday afternoon.

Intercooler tank should hold a bit over 2 gallons of coolant (8 liters). I will be re-using my currently fresh coolant for the radiator, which takes a bit less than 3.5 gallons. If you're using all new fluid I guess you'll need 5.5 gallons.

I'd also like to know about hoses - specifically do we need to buy that extra hose for purging the intercooler system of air?

From reading wildwhl's old install threads, you're supposed to stagger the wire cuts for the new harnesses so that everything fits in the looms after you put the crimps on.

Taking the nose off makes the job a lot easier, and quite frankly you almost have to when mounting the radiator for the intercooler.
(radiator removal).

Drilling the hole for the crank pulley pin is duck soup compared to removing the bolt, but it is a downhill job from there.

Don't stick the windshield washer arm on a grinder without removing the connecting arm (it does "pop" off if you stick a lever between it and the arm and pry gently). You might also take some time here to remove the rough edges from the washer assembly casting as they are sharp!.

Be very aware of the wiring loom behind the maggie pulley. If it isn't secured out of the way you can grind through it (not good).

You can bypass the Magnavolt if it fails so you don't get stuck.

Get a shop vac ready to vacuum out the valley after you remove the intake manifold (clean up everything before install). This will also give you time to inspect your cam.

Don't do any "half-ass" wiring.

ALEVE is your friend.

I assume that it's the passenger side washer arm that we're grinding because that one could have a clearance issue with the new manifold? I don't think it's that clear in the instructions but my common sense says passenger side.

For the life of me, I couldn't mount the HEX as Magnuson shows. I made up my own brackets and mounted it my way. Same with the routing for coolant lines. I also reversed the order of the reservoir and the HEX from their diagram.

You've got some leeway in how you route all the hoses/harnesses under, over, and around the maggie itself. We'll wait till you get there. I'll take pics of anything you need, not that I'm any expert by any stretch ... just been there, done that. Mistakes help you learn; heck, I must be a genius then. :nono:

Something to do with the supercharger, or just good to do on an LS6?

I had 3 Magnavolts go bad. It ended up being bad grounds. For the 4th one, I took some heavy gauge speaker grounding wire and ground the damn Magnavolt in 4 spots. It never gave me a problem after that!

Thanks to everybody for your input. I'm reading up on some old threads right now. But since this such a big project, every little bit helps.
Keep em coming!

It's a big job but it's not all that hard and in the end it's very rewarding. I used a ball joint puller to remove the wiper arms since they were very tight. I had to remove the hood to get the driver's side wiper off. Nothing too hard. I also took my front end to a body shop and had all the chips and scratches taken care of while it was off the car.

I would highly recommend an air compressor and an air rachet. It made everything go way faster. Also take the time to torque everything properly.

It's already been said and it should be obvious but make sure to take your time on all the wiring. One bad connection will cause you a lot of trouble. You are cutting so many wires it would be almost impossible to diagnose a problem when you are finally done.

Good luck.

Yeah, find the thread on the guy who sawed through his harness!:helpless:

Don't be cheap on cable ties and be prepared to cut a lot of them off when you reposition stuff to "neaten it up".

Be sure to secure the rear harness as close as you can to the firewall.

Remove the battery and the wiper unit and facia and you will be suprised at how much room you have to work with.

With the nose off and radiator out it's a cavern.....:histeric:

The space in front of the crank pulley looks tight, even after the space is opened up from removing the radiator. I there anyway to fit a normal drill in there for drilling the pin holes, or do you definitely need a right angle drill?

Do I need to buy an hose for purging the intercooler system of air, or is there an extra hose in the kit?

I bought a right-angle pneumatic drill from Harbor Freight. For having eleven-year-old female gymnasts, that Chinese drill worked great! :rolleyes:


... As for purging the sysem, what I did was attach very long hoses and let the pump just run into and empty a bucket as it circulated fluid through the system. ... I don't think there is an easy way to purge the system without spilling at least a pint of fluid on just about everything.....
Heavy's right, as usual. I've got a photo of what I did ... very crude, but effective. Rick thought it was great; he had basically came to the same conclusion that that was how it could be done, so we were of the same mind. I'm on the laptop, and the pic is on the desktop in the office in the other room. I'll post it tomorrow.

Wish I had an overflow/reservoir tank of a liter or so capacity hooked to the exit from the intercooler. As it is, adding or even checking the coolant level in that system is near impossible without dribbling coolant all over. Maybe with these guys doing their install, we'll collectively figure out something that's a little better. I think Rick figured out something, but I didn't pursue it back then. I'm up for it now. Hey, heavymetals, how do you check yours? Got anything fancy?

I had plenty of room for my SEARS 3/8" with the radiator out and the nose off.

There really isn't anything in the way after you remove them.

The A/C condensor isn't in the way, but you don't want to go bashing into it either.

As for purging the sysem, what I did was attach very long hoses and let the pump just run into and empty a bucket as it circulated fluid through the system.

After install, you can loosen up the brass screw and syringe (a turkey baster works great) fluid in to top it off and release some air if any is left.

I don't think there is an easy way to purge the system without spilling at least a pint of fluid on just about everything.....

This is great :highfive:. Cant picture some of the things you guys are talking about. But I know when I'm in there, I'll be like,,,,so that's what they were talking about :yup:

Take your time and do it right. Front is worth taking off. I did mine with only 1k on the clock. The hardest part is all the cussing you will do getting the crank bolt to let go without breaking your breaker bar and putting a dent in your fender. It needs a hump hose at the air box otherwise the torque will pull the cheapo smooth hose off and dust motor..

.. and the sweet sweet sound is worth the trouble... Music

and it's Perdy too...

Agreed. Are you still working on anything?


Also, here's a better way to route the intercooler coolant flow (NOTE: You have to reverse orientation of the HEX.) and the second pic is how I purged the system of air bubbles (crude, but hey! ... it worked!):

So as to provide a measure of stealth when you pull behind someone, you may want to subdue the the glare of that bright aluminum heat exchanger peeking out from behind your grill.

EDIT: Oops! Pic is not uploading.

It's safe to just spray the thing? You just tape off the hose connections and the rest is ok to spray?

It was a couple years ago that I installed the s/c. This thread brought back some memories.

The install is very easy if you have any mechanical ability at all

The only time you really need a second set of hands is setting the unit. If you're built like Micheal Phelps then maybe you you can set it yourself.

Pick up a 2 foot piece of inch and a half steel pipe - you'll need a cheater.

The rad for the intercooler does not fit exactly as the instructions say - so be prepared to make very minor mod.

And if I was doing it again, I'd paint the sides of the new rad black. It's really not the reflection that gives you away, it's the whine of the maggie and rumble of the exhaust. But I don't like the glare through the mesh.

I have two PCM's - the original with the Magnusson modified tune and one with the Stealth tune. I didn't know if the Stealth tune would pass state emissions testing. A true waste of time and money since last time I left the Rick modified PCM in during testing and the car passed.

Last - enjoy the install. It's easy and fun. And the sense of accomplishment and thrill of the ride makes it worthwhile.

Tony Be careful as to make sure that your hood does not touch the top of the throttle (may need to shave off the top a bit). As my 05 maggie on a 06 LS2 sits a bit higher and is almost ready to break through the hood. Finally determined that the way we had to fab to fit the 06 made it to sit a bit higher. Oh well - Just about ready to get a cowl hood (Darn if I must). First I thought and also Bill @ Lindsay that it was my MM not holding the maggie in place strong enough, but after the install of MM the engine did not torgue as much but still hits the hood.

Just take your time and always helps to have another technical hand to work with you.

Good luck - Another maggied V at the VII day -

BTW - How many maggied V showing up at the VII dayn - I wonder??

Yep, since I already have mine I have been emailing a forum member who is a machinest about modifing or making a few more for the newer maggie crowd.

What it may come down to is:
the cheapest way to get it done is to ship the replacement and then have the original returned for modification.
Just a question of either capping off the original hole or screwing in a pressure transducer for fuel pressure monitoring.....

Don't you fools know N/A is the way to go?



hahaha, seriously, have fun guys. I'm just waiting for V2 to have a soopercharged V...
Could there BE a worse time for you to bring that up?!!

and what's with the ,,, deal? The period key is one to the right...
Uh,,,,,,:spamkill:

Easier than that even. Fab up a wire to short the two new wires that you run from the trunk up to the magnavolt connector. If it fails, just pop the connector off of the magnavolt and plug in your jumper wire across the appropriate connections.

Keep the jumper wire, a spare belt, and long wrench for the tensioner in the trunk just in case....

Toss in a photocopy of the belt routing as well if you are paranoid...
lol I was thinking of a toggle switch. But that's like waiting for it to happen (like the wire cutters are any better :rolleyes:).
The breaker bar is always in the car anyway. Just have to put a 15mm next to the 19.
