    New guy out in DM

    Hey everyone what's goin on? Just now figuring out this site even existed lol. From Indy just south of Des Moines, and love to rock the odd ball gm's no one else ever waists the time or money to build lol.
    Got an 06 cobalt ss as my dd that I turbo swapped and put the f40 6 speed into, and about to go e85 with it but I just got my other engine back so it'll have to wait a lil longer. My big build is a 00 grand prix Gtp that I'm also turbo swapping but going with a full engine/trans rebuild looking for some big #'s and setting it up for the strip/street... anyone on here ever go downtown dm to "socialize" on the weekends?

    Welcome, there were a few GTP/Regal guys on here previously (batwood and fifdy) they have both moved to different platforms now but still on the site. Batwood's regal was actually twin charged for a short time.

    I thought about the whole twin charging thing but that just seems nightmarish to me tuning wise lol. Any clue what they was doing for #'s? I'm going for 600+ on e85 and a 6766.. prolly not many cobalt guys on here either is there? Seems like jus allot of good ol v8 guys (which is what I prolly shoulda built instead lol)

    Batwood made 311 to the wheels then went twin charge but could never get it tuned the tranny wouldn't hold and a bad pcm wouldn't allow for a good tune.. i belive.

    i don't see how twin charging would make the tuning harder. your computer, map sensor and iat (speed density) and wideband doesn't give two shits if the air is compressed by turbo, supercharger, leaf blower or all 3 put together

    but i can see sizing stuff properly, routing and pressure control possibly being a pita

    yea from what I'm understanding (my theory anyways idk if right or not but hey) is that the eaton m90 that we have on gtp's isn't like a centrifugal supercharger. It don't actually gather the air compress it and shove down and in, it's extremely inefficient and just acts like a big huge retarded fan that's hotter than holy crap and spins up to about 10,000+rpm so when you shoot the compressed cooled air(specially higher up in rpms) past the maf and then hitting the hot retarded fan like supercharger it just spins threw the rotor pack and makes pressure/turbulence issues and messes everything up. Plus everyone I've talked to/seen said it really inhibits the turbo from doin 100% specially up top....

    your not by any chance the same supra running around downtown on the weekends are ya? lol

    Needless to say the trans went bad in my gtp to about a year and a half ago and that's what sparked this big build lol. I was playing with/building the cobalt too so it got put on hold for a bit, but I jus got the cobalt dyno tuned a lil while ago (362whp 321tq) and she's running strong still so its time to finish my prix lol

    Don't church it up Matt, they're both white.

    Newgen has the big wing. He's compensating for something.
