Is magna charger still the #1

A magna is great out of the box and with a few additional mods can make more reliable power than your stock tranny can handle. Once you get over 7 psi boost plan on a tranny rebuild soon if you like to romp on it a lot.

 

My reccomendation for someone just beginning this process would be the magna with a 3.1 pulley, a high flow intake so the blower doesn't have to work so hard getting the air in, headers/ exhaust with high flow cats. this will get you into the high 12's and your tranny should last you a while.

 

If you start with the intake and exhast which nost guys do anyway it will make the blower more effective. If you have the money to do it all at once go for it.

 

Now if you just can't stop yourself there get a 2.9 pulley that will get you up to about 8.5 boost don't forget to upgrade the belt or belt slip is gonna be a broblem. Going with any higher boost on the radix isn't really going to do you much good on this style of SC guys have done it but you don't get much return and reliability goes in the crapper above this level. Also upgrade the intercooler it makes sense at this level of boost to reduce the intake temp as much as possible.

 

A good blower cam is a good idea at this point to take advantage of all the extra air. There are several grinds out there that will work well but the best is an ongoing debate.

 

You will also need a preformace tune done or get your own prgram like HP tuners.

 

You can also expect that tranny to go rather quickly it just can't handle the power in stock form. A good performnce rebuild should be in your plans and might as well get a new stall while your at it. In my opinon a 2600 or 2800 stall is the best choice if you are gonna still drive it on a daily basis. Billet servos, shift kit, hardened drum, kevlar bands etc. all should be part of the rebuild.

 

At this point you should be in the low 12's, on a good run maybe break into the 11's. That's a lot of additional money and work just to pick up one second.

 

If you are planning on going this fast I think there are better otions in the long run. I love my set up but it's high end limit is lower than other options. Of corse when i started there weren't all these other otions out there.

 

If 13 sec 1/4 are good for you then the radix is the reliable choice, if there is no such thing as to fast then I wouldn't choose it.

 

My best time with all the above done is 12.02 at 115 in the quarter. I know one guy who has gone into the 11's with a similar setup (probably had better tune). But I have over 50k on my truck and drive it every day. It is solid reliable and fast.

 

All that said I'm going with a high end pro built 408 set up for a procharger. I'm gonna see how much the stock all wheeel drive can take.

sounds like a great explanition of experience BSER :cheers: Now i am kind of curious what the benifit of the MP122 blower is and also i have noticed that the intercooler pumps on the stock radix is real slow and dosen't flow coolant like it shoud IMO. Has anybody upgraded this or still unherd of here?
