SuperCharger vs TURBO

I was reading on another site someone had a supercharger on a 6.0l and was dropping boost at wot(from 9.5 to 5#, and his friend had a 5.3 supercharge and boost was just 2# lost WOT. He thinks its belt slip(and he change belts a few times and diff brands)

SC guys is this something that can't be worked out

I'm old school SC, but it looks like if you want power/less problems on the eng. turbo is the way to go IMO

I never liked a TURBO because of rear mount and lag, but with the new FM TURBO its the best of all worlds. My one problem the heat build up, I live in the south will the heat of the day and the turbo under the hood will give problems

I talked a few times with Allen(he sold me on the fm turbo) and I saw some pic from allen site and tricks site, I like to get some feed back from people that saw the setup and/or seen it run and what you think.

thanks

I like my Procharger, but I got the kit at a steal. If I was starting again, I'd go turbo. Probably the FM from Trick Allen has now.

Side note, my Procharger makes 10 lbs consistently at WOT. Get the right pulley (Reichard Racing grooved pulley), the right belt (Gatorback), and the right size belt (mine is the smallest possible) and belt slip is gone. Radix guys can get the larger idler pulleys which give them more belt wrap.

Plus a turbo is free HP, doesn't take HP to make HP with one. The only time you lose HP with a turbo is if you build a low compression engine to run mega-boost. Once the turbo starts spooling though you get all the HP back and more. I guess you could have too small of a compressor wheel and run out of boost up top but that will be avoided if you buy the right turbo from the get-go.

A few questions....

Do you ever haul/tow heavy things????

You do plan on a intercooler correct????

Increased exhaust backpressure causes parasitic loss but not nearly to the extent that a S/C causes.

I like the Trick kit, they just want too much for what it is IMO. They have maybe 1500 in parts in the kit and are they are asking over 5K for it without a FMIC :eek:

I see MAGNA CHARGER has a larger unit out the 122 did you hear anything about it

122 is much better than the 112 for a 6.0L

No need for the T76 on an LQ9 where you are only going to be able to push 12#s safely without going to a lower compression motor. A T70 would be closer to what you want.
Here is the consumption chart for your motor
http://www.forcedinductions.com/consumption364.htm
Here is the compressor map for the turbo you "should" use
http://www.forcedinductions.com/imag...20maps/t70.jpg
With the T70 at 12#s you will max it out at 6400ish which will work well with your shift points and still give you much better power down low since you are in the peak of the efficiency island for most of your power band till right at the end where it is still very efficient but will still not have hardly any lag and give you good power throughtout the band instead of the semi-laggy and peaky power that the T-76 will give you. I suggest you check out forcedinductions.com and start reading on how to select the proper size turbo because the T76 isnt going to get it done as well unless you are going to a bigger motor later on but you will sacrifice a decent amount now.

EDIT: upon further inspection you will be in the peak of the island for the whole powerband which means great power from the time you stomp on it till the time you let out. 3400 to 6500(36-70 lbs/min) which is peak efficiency for that turbo.

thanks for this info, it look like the t70 is the way to go. I was just looking at some notes and allen also say the t70 with 10psi or so will do it.

what do you thing about installing 60# inj.

if i remember correctly the 122 needs to go on anything 6.0 or larger....the stock pulley it comes with will produce like 12#'s boost on a 6.0...it would prolly be like 15#'s on a stock bore 5.3.
the 60# injectors are what you need to go with also..you have room for a lil more than the 42's...

60#ers all the way
