GT42Mag

[ChevyDieselLLY]

yea i would bush it down. how hard is that to do? so Ed i should just stick with a GT42 and not the mag, or is there something else out there that you feel would work good. im not gonna lie i dont really know a thing about chargers.

i guess when i say i dont care about the track its mostly just becuase i dont want to have to deal with the saftey stuff, even tho i know i will have to deal with it for pulls.

"No safety stuff".......that puts you at 11.50 at the track.
Almost any 2.8" charger on top of a well built motor will get you to 11.50.
I will confirm this..........my 2.8 bushing in the 42 took ALOT of power away!!!
Also, I really don't think I would try to bush a 3.2" charger down to 2.8". (assuming that you will pull the 2.8 street class)
My old GT4094R was a sweet set-up!.......I'm sure you could run mid 11's with a good motor and tuning and still have AWESOME streetability! That might be a good choice?............prolly get the largest exhaust housing since you won't be towing.
GT4094R is 2.7_" so you would be in between the 2.6 and 2.8 pulling class.
I think you would be competitive around here in the 2.8 class..........but if you wonder out to the mid-west...........maybe not..........
Your other option is to go "outlaw" and shoot for high 10's without the rollbar. I'm stuck there for now.

its not hard to use a bushing but make sure it the right one for the charger.

Indeed......but do be carefull!............I learned that the hard way. It almost cost me a turbo!
MAKE SURE IT IS SECURELY ATTACHED!!! Harmonics.......or what-ever it was, caused mine to 'walk'. I got lucky and caught it in time.
My reference is to a bushing that you want to take in-and-out often.

Ed your gonna hate me but when you say "outlaw" what do you mean exactly? also i dont want to come off the wrong way but why did you change to a larger charger if you liked your 4094 so much. do i just need a roll bar to run faster then 11.5 or a full cage.

Loosely translated.........outside the law or rules. The term is normally used when some racers want to go beyond the existing rules.....usually with power-adders or wieght, etc.
My use of the term is more about the safety rules................maybe I should call it "running ROGUE".

I went to a larger charger cuz I wanted to go faster, silly!

11.50 requires a roll-bar.........9.99 requires a cage......as I understand it. I might be off on the cage times.

if you are planning on doing mostly sled pulling i would have to say that the 42 mag will be too big for the 2.8 class because when you bush it down i would have to assume that you would snuff the turbo out at WOT

But what do i know:dontknow:

alright well i guess i will not go with the mag and just stick with the gt42. which also means i will need a roll bar. who wants to help me with that.


well i guess i can let the cat our of the bag now. the main reason i was looking into the GT42Mag was becuase i was going to build myself a 7.1 Dmax. but i have since been you could almost say talked out of it. so with now not adding the more ci i think the gt42 will take care of all my needs.

 

[Jared Duramax]

come to charlotte i got your man. call me and i can get you his # he does some of the best tig welding i have ever seen and produces very clean looking cages

 

[eds04max]

carefull with them bagged-up cats now!

 

[ChevyDieselLLY]

haha yea well its not gonna happen at least not for me so i say why not let them out. would have been cool tho.


Jared didnt you have some posts somewhere in between mine and Ed's?

 

[Jared Duramax]

i did but lets stay on topic here

 

[ChevyDieselLLY]

what type of RPMs would i need to turn for something like a gt42 or gt42mag? and how would i get those rpms safely.

 

[McRat]

GT4202R is going to like 2700-4000 (racing range)
The GT42mag is going to like 3000-4500

The factory valve train seems to do OK at 4500, but I feel safer with high speed springs. Keying the cam and crank should also be done.

 

[codyn]

from what i have seen with the 42 charger i had i would to update the springs.

so rods, stage 2 heads from SoCal, race cam, keyed crank, billet main caps, duel fuelers, 60% over injectors etc. be fine to run a GT42Mag at the right rpm or would i need something else. i know tuning as ALOT to do with it but also the parts.

im so glad this site is here for my stupid questions :hug:

 

[SmokeShow]

I'd throw some ARP studs in it top and bottom as well some forged Mahle pistons.

 

[ChevyDieselLLY]

yea that was part of the etc. just got tired of listing everything. pretty much i have in mind doing everything but making my engine a 7.1 as you can see from other posts it was thought of.

i am just not sure about this entire rpm range thing. lets say i go with the Mag and like Pat said i will have to run from 3000-4500 rpms now is that for racing to get the max out of it or just have all my tunes turn that high. also how well would running at 16:1 for comprestion ratio.

whats the limit on questions until you get banned

 

[RENODMAX]

I would NOT do forged pistons for a daily driver or really any street truck for that matter.
