Supercharger question

[dunes_av]

I am contemplating putting the magnacharger "radix" supercharger on my Av, as I am wanting a bit more grunt. Just wondering, if I go with a low/moderate boost to keep reliablility can I still run 87 octane fuel or do I need to run 92 octane?

I was wantin to lift it, but lifting my truck will erase any chance of it fitting in a garage, and a supercharger would be just as much fun. I do mild offroading, nothing that could not be done in a stock Av, but perfer the look of the truck lifted.

Any advice in general from those running a supercharger on thier AV?

Regards,

Grey

1st, Please do a Search as there is TONS and I do mean TONS of info on this subject.

2nd,I love my RADIX. IMHO stick with their tune, their level of boost and run the 92 octane gas.

You are almost guaranteed a trouble free installation.

I suspect that you will need to go to 92+ octane, especially in the hot climate you live in [even with the intercooler which I surely hope you are getting]

Yep the radix comes with the Intercooler, Its a Sweet Setup!!

I did a search before posting, found talk of new injectors and such, but not much mention on the fuel needed when adding a supercharger.

I want more power, however to spend $4000 +++ to make it so I have no choice but to run high price 92 worries me. I know it is a double edge sword, as just like they say it takes money to make money, it takes money to make power.

Just so everyone knows, I am not going to take my truck to the track or anything like that, just want more power for everyday driving, (and yes I do have a bit of a lead foot).

The main draw for me to the radix is the optional powertrain warrenty 3/36,000, (according to tbrynes site $200) seeing as how I would be voiding my factory warrenty, this is a big benifit. Also everyone on here seems to lean towards the radix when it comes to reliability issies.

Premium fuel is required. They even give you stickers to put on the vehicle to warn people not to fill it with regular.

Well the radix has certainly gotten a lot of air time of late. Don't know that their stability is any better than any of the other established units.
My experience is that you will need to run 91. And I am in a lot cooler and dryer place. I even tried 87 with 2 bottles of octane boost. Mistake. Knocking was so bad sounded like there was a party in the engine.
Do you have details on the warrenty. I do NOT have the details myself but have seen it written elsewhere that it was more of a feel good thing.

I passed on the warranty. I didn't like the fine print. My recommendation would be to get in touch with Tom Byrne. He will have no problem faxing a copy to a prospective buyer.

sparky,

I do not have the details of the warrenty yet, but I will find out before I do this. I know it would be a hassle to do a warrenty claim no matter what, as magancharger will say faulty stock part, GM will say it failed due to the supercharger and there fore will pay out of pocket anyway.

hmm, maybe I need to take a trip back up to Calgary to see your truck and see if I would be happier with a S/C.

Then go for a few at a local pub. (I miss Calgary, but not the winters)

Ah, come on We havn't had a real winter here in about 5 years. The locals are getting spoiled. If we have a cold winter this year they'll freak.
I must admit I am having more and more fun with the SC, childish as that may be. The truck just seemed to be running great this weekend. Hit the gas a little too hard a couple of times this weekend pulling away from a corner and wasted some rubber.
Can't wait to get my new winter shoes, but I think I'll have more issues with wheel spin. The Toyo's are not easier tires to spin. The stock tires are downright simple.

 

[dunes_av]

-40 C without even including wind chill to me is a real winter LOL.

With winter tires being softer rubber probably have to watch yourself more so that you might be able to get 2 seasons out of them LOL

ANYONE: Do those kind of temperatures make for a harder start with a supercharger

I had no starting trouble last winter. The only possible issue I can see is the exra drag on the starter created by the supercharger drive belt/gears etc.

The fuel/spark setup for starting is still stock, even with a supercharger.

Yak, as long as you plug in your Av, I dont think starting should be an issue

Yak, for what it is worth, I find mine starts better even when the engine is just cool when i use the remote starter. Go figure?? I think it is becasue it throws some fuel in first.
