Yeah, stock pump with a hotwire. Its a L26 short block with ported heads with bigger valves, ported lower intake, ported blower, VS cam, single roller chain, LS6 springs, ati super damper, Pacesetter headers, zzp 3in exhaust, 60lb injectors, e85, trans has been beefed up alittle. I tuned it myself. Its currently at 19degrees timing with very minimal KR, at least last time i scanned it. I really need a permanent KR gauge of some sort. It went 13.5 @103mph on shit street tires with a 3.4" pulley. I was hoping to get into the 12's with a drag radial and the 3.2" pulley thats on it now.
Engine Shop that knows 3800's in chicagoland?

meh. the intercoolers are simple enough. plenty of factory vehicles with parts you can steal also nowadays.
get a core and piece together a kit.
Not bad at all! I was alittle disappointed with the 13.5 but it was very traction limited to say the least and 103 mph i think is pretty good indicator that its making good power.
I have an intercooler and E85. I don't think they compliment each other well. Both absorb heat, so it seems to me one or the other.
If each one gave you a ½ second improvement separately, together they would be 3/4 a second, not the full second. (Just my opinion.)
My intercooler core started leaking, so I blocked it off for now. I put on a bigger pulley and retarded timing a little, but not nearly as much as I thought I would need too.

An intercooler absolutely compliments E85, an intercooler would compliment a bone stock car. I've tuned a lot of 3800 cars and the ones that are intercooled are 99% way easier to tune for than non-intercooled. You're probably having bad luck with it because you're running way too small of a pulley on a basically otherwise stock car. I'd bed that car gains 30whp with a 3.0 or 3.1 and a good tune with a bunch of timing than what you have right now. You're spinning the FUCK out of that blower robbing tons of power and there's no way that engine is flowing it, probably just pilling up boost for no reason.
I've tried larger pulleys with up to 24° advance and people here were freaking out that was too much timing. Now you freaking out my pulley's too small and you don't even know about the 2.7". I love this place. 
Not having bad luck with the car at all, other than it being a magnet for uninsured drivers. Oh, and cracking flexplates.
I totally agree a intercooler compliments a bone stock car. So does E85. Together, not as much. Both remove heat and are trying to do the same job. If one does the job well, the other has less benefit. Just sharing my experience.

there is 100% better 3800 info on here than any other site that's out there...
yup, turbo it, blow it up, junk yard motor repeat. when rear strut towers rust, add 4X4 wood support, when undercarrige rusts out junk it.
best advice anywhere!
3800's
Really?! Gonna need a tune coming up soon. Maybe in a month or so...Picking up my GTP from welder on Saturday. Need to fix a few things first though. Is an in-car tune something you could help me with?
Hmmm... maybe. Coming in at a close 2nd I think.

grandprixforums is back. Was a (.net), now it's a (.com)
Came back to life after being archived and then reloaded by some serious GP loyalists. I don't know of any site that has more How To's and more detailed info on 3800's. Some good info posted on there. Especially when James was still active. He would keep us all in awe with his mastery of 3800 folklore.
nevvvarrrr
when i turbo'd my gtp, i used here and Club Grand Prix! Your online Grand Prix & G8 resource
