Maggie non -intercooled VS. intercooled?
Just looking for street fun! A non-intercooled maggie can save me a grand$, so why not it vs. the intercooled unit. Not for competition, just fun. I could use the extra savings for intake or exhaust mods or ?

You would be really limiting the output without an intercooler. If you are going to spend 5k, might as well spend 6k and do it right. I think a more sane area to save money would be choosing non-polished over polished.
Roots style blowers like the magnacharger can really heat up the air temps. The cooler the air, the MUCH better it will run. IMO, I would not run a magnacharger (or any forced induction) without an intercooler. It can be done, sure, but like I said before... if you are already spending that much at least do it right the first time.
My last truck had a magnacharger, but there was no option for the intercooler. It left me only with alcohol or aquamist options to cool down air temps, which need to be refilled. I got a 60% increase in hp/tq on the dyno with a smaller pulley, but I could not go any smaller than that because the higher boost was being contrasted by the higher air temps...even though I was not yet at the mechanical limits of the blower.
That said, if its just for street fun... why not throw in a 4.10 rear and call it done? That will give you a kick in the pants for half the price.

Definately go with the intercooled version for the reasons mentioned above. I don't think we sell any Magnusons without the intercooler now.
DefenderC5: I believe that was the side mounted kit from about 5-6 years ago? I used one of those on a 6.0 Suburban. The intercooled Radix makes more power and it isn't has loud as that one used to be.

Like with ANY mod/s, it`s a good idea to talk with local owners in your area about their experiences.
Watch this section near the end of the month for the Corvettes and Cobras meet in San Diego which happens the first Sat of each month in Mission Valley.
There are several blown Vettes (Maggies and Cent ) that you can speak with, while you`re at it join us on the cruse to see the cars run 1st hand!

There is also a very noticeable difference in power between 75 and 40 degrees. Feels like you did a pulley swap!
sdspeed: We have some very good sale prices for the Magnuson. Give us a call at 1-877-482-9763 to receive a quote. The savings can be use to gettting a free intercooler upgrade

Yep, I remember when it was 40 here in So Cal one day a year or so ago.

YES: Do it right the first time! It is also prudent to invest in an upgraded radiator when installing any new forced air, or, turbo induction system, as well as, whenever considering larger cubes, etc.. In fact, Ron Davis is just one of the many heavy duty high performance radiator manufacturers producing an upgraded radiator more than suitable for the task. Moreover, while planning such a mod, remember to also consider installing a high performance Radiator Fan to assist in cooling engine temps. Spal Radiator Fans have been an o.e., and, high performance upgrade fan system for Hammer conversion Mercedes Benz and Gemballa Porsche, etc., for years. FYI: The o.e. Corvette C5 fans run at approx. 1550-1750 CFM. The Spal Radiator Fans run at well over 3,000 CFM. Spal manufactures high performance Radiator Fans for the Corvette C5, and, are available at Dewitts Radiators, a Forum Vendor. Good luck to you.

Intercooled vs. non-intercooled
Besides all the good info above,the intercooled version is the only c.a.r.b. certified version of the maggie that is legal in Ca.
Might as well stay as legal as......possible

There was no room on the 3.4L V6 to fit an intercooler between the blower lower intake manifold. Made for some pretty hot intake temps. The power increase was pretty good nonetheless, 235hp/265 tq to the wheels over the stock 150whp. Not too shabby for a 6 banger through 33 inch tires. Was a fun little sleeper/trail wheeler.
Would have loved to have had an intercooler option for it, though.

Never mind the extra for the intercooled Maggie...
...start working on the budget for new hi-rise hood, air intake, pillar gauges, more clutch, and hardened output shaft...and more tire with new wheels to put them on...!
The $1K for the intercooler will look like chickenfeed by the time you get there
btw go intercooled...

Don't do the gears!! yet.
If you are seriously thinking Maggie I'd hold off on the 3.90s for now. That is going to be way too much gear for the street if you are pushing 500+ rwhp.
