Any adevantages of buying the non-intercooled mag over the intercooled mag? I see alot of guys on the forum getting some good horsepower out of the non-intercooled mag.

Thanks

Guys

 

Get the Intercooled version.

 

I'd talk to ECS. They seem to get great numbers out of the non-intercooled unit as you mentioned. The I/C included with the Mag is a joke.

 

here's my reasoning....

small coolant reservoir...
small heat exchanger...
small intercooler...
intercooler in the middle of airflow path causing airflow restriction thereby lowering intake cfm's, boost, and power levels and acts as a heatsink as it will warm up since it's right on top of the engine and below the intake
large cost compared to alky injection kit which will do better reducing temps and will give you more horsepower as well

do a search...there are extensive posts on the topic

 

I think a water/alky kit with the non-intercooled setup would yield better power potential

 

Ok here is a question for ya, if you have a I/C Maggie can you remove the I/C internals and make it a non I/C Maggie?

 

Now that's a good one...I'm not sure about that....my guess would be yes as the only thing you'd be removing is the intercooler that sits on top of the engine as the rest of the parts you just would not install (tank, exchanger, etc) or would uninstall. However, the non intercooled intake base might be different...but since you can retrofit to an IC'd I don't know why you could not do the reverse.

I'd talk with a tuner or directly with Magnacharger....

 

Thanks, I'll run it past Doug!

 

Hey Mark,

I dont honestly understand your reasoning. If you are comparing an I/C Maggie to a Non I/C Maggie w/alky your comparing apples to oranges. 1) It is obvious that a non I/C maggie will make more power w/alky.
2) It's been proven that an I/C Maggie makes more power than Non I/C.
3) It's also been proven that an I/C Maggie w/Alky makes more power than a Non I/C Maggie w/alky.
Sometimes there is a necessity to have both. In my climate I need all the cooling I can get. The cooler the charge the less chance of detonation (But I know you already know that.)
The main thing that I see is, is the additional cost worth the additional protection and or power???

I do agree that the I/C Maggie is probably less efficient due to air flow restrictions. But that just proves that the cooler IAT's do a better job than the airflow.

But..... I could be way off. I could have just taken too many pain pills so I am only making sense to myself.


BTW, You should fly out here next weekend. The ECS boys will be out here trying to kill their livers...

Man Jeff, had I known I would have made the trip....first off cause it's Vegas and to check out your ride and all the other awesome ones there you spoke about when we last talked, and party with one of the premier C5 tuners and get them drunk and have them spill all their secrets

Pain pills or not you're still making sense, but I've had a lot to drink so maybe we're on the same level. I agree with #2 above but only with 1 and 3 when comparing the Non I/c with the I/c with the stock pulleys they come with. Magnuson put a smaller pulley on the I/c version which is what I feel is making the additional power over the Non/ic. I do feel the lower IAT's play some of a part there but personally think it's minimal. I feel they did the smaller pulley to overcome the airflow restriction.

I'd like to see a straight up comparison using the Non IC 3.5" pulley on both or the 3.4" pulley fron the IC'd on both to see what's what. Problem is that so many setups differ even in small ways that it would be so tough to do. Anyone want to lend me their Intercooled version and I'll swap my 2.8 pulley on it and see if we can get a tuner to tune it for free in the name of Research and Development and the general good of the C5 Community?

Can you direct me to the setups you've seen that show the IC'd w/ alky is proving better? Seriously, all I've been able to uncover is the opposite and I've been looking hard for a while. I believe intercooling is the way to go and alky on top is just gravy but with the size and placement of Mag unit I haven't been able to justify doing both.

But for you, with 120 degree desert heat, hell yes you need all the temp reduction you can get....but it will be great to have those IAT's low and be able to pound on it whenever you like.

I'll make it out there sooner or later....my girl and I actually thinking about having our respective bachelor/ette parties out there in September.

 

THAT is EXACTLY what DOUG at ECS just posted in a recent thread here and i confirmed another top opinon of a well known tuner who also agrees with the above proposition!!!

 

As several others have suggested, I'd go with the non-intercooled Maggie. I don't think the results you see with the intercooled version are that great. I'm another one who'll be ordering the AI from ECS before long.

 

for central Texas the I/c mag is the only way that I would go, but it is a proven fact that any I/c will cause a flow loss and preasure drop (around 1 psi in our case). The Mag is flow limited in the c5 application so the non-i/c CAN MAKE MORE POWER with the same size pully but you had better stay ontop of it all the time. To me this is not the way to go, if you need over 500rwhp and rwtq then go to a procharger or TT.

All in all the non-ic with AI can make about 30 hp more than the i/c with AI (1psi~30hp on the LS1) but this is not worth it to me considering the area where I live.

Now the KB will be a whole new ballgame, I hope to heck that they put a I/C on that one so that we can turn it up to 15 psi.

If you really want more hp add a 100 shot in front of the magie lol

More Than Zero

ps IMO the i/c maggie is right in a sweet spot for the c5 after about 500rwhp a lot of things start to go wrong, and I see a lot of people with acam and max bolt-on's getting to the 500~530rwhp range with the I/C maggie with out a lot of BS to deal with.

 

If you are having problems with heat soak in the IC check the plumbing. The tuner here on the EastCoast that I had originaly install my IC mag had the plumbing reversed going into the resevoir. It runs much cooler now

 

We have had success with both. I would not shy away on a good deal on a non interccoled version if you find one. We have had both produce the same numbers. The biggest difference is that the non intercooled one will heat soak a bit more. Most all the mags we are doing we are running our alky kit on with great results..

 

Isn't that the whole point of an I/C. Lower IAT safely allows more boost. Smaller pulley provides more boost. Stock to stock, the I/C makes more HP. Add alky to both, and it probably still will. But a lot of it is tuner skill.

BTW - FI is all about providing more HP gain than the losses of that particular system (backpressure for Turbos, parasitic losses for SCs, air restrictions for I/Cs) so if the intercooler provides some air restriction, yet ultimately makes more HP, it's up to you if you care or not. To me, it's doing it's job. If you're after ultimate HP, the Maggie shouldn't be your first choice, anyway.
