Yet still, we lurk. :o

@  ejguillot : (27 September 2020 - 01:08 AM)

Yeah, Facebook took over and killed forums.

@  dezldave961 : (26 September 2020 - 03:24 AM)

Ya, most of the original wave of active members have changed vehicles to something (probably) less mod-friendly, with the occasional person in an LS or Hemi that they do some bolt-ons to. Kinda sad that forums faded.

Finally updated my signature to match my current Buick.

@  ejguillot : (10 September 2020 - 03:20 AM)

Things are terminally quiet around here...

Just became a moderator on 3800Pro, so that's fun. I know it's gone thru a couple hands since Intense got sold, then that guy sold the forum. Not sure what that'll help, but it's something.

@  ejguillot : (26 July 2020 - 02:47 AM)

Glad to hear it. Would be a tragedy for us remaining owners to lose the knowledge in these forums.

@  dezldave961 : (12 July 2020 - 01:55 AM)

Hosted a buddy and his family for cookout... Ya, not alot on forums lately. Just keeping the lights on.

@  ejguillot : (08 July 2020 - 03:16 AM)

Everyone have a good 4th? This place is a ghost town...

@  dezldave961 : (07 May 2020 - 04:14 PM)

Got bored and started making build video...

@  dezldave961 : (04 May 2020 - 04:05 AM)

I need to hunt down the little black trim bar that's at the top edge of the GS rocker panel cover, for driver's side between rear door and wheel well.

@  ejguillot : (03 May 2020 - 02:42 AM)

I've been on there too. I hope this forum is kept open, there's too much info to allow it to be lost!

@  dezldave961 : (24 April 2020 - 10:25 PM)

I've been monitoring GrandPrixForums and 3800Pro (don't have FB)... also hopped on TurboBuick, but 99% GN chatter from boomers

@  ejguillot : (19 April 2020 - 02:33 PM)

Everyone at home, plenty of free time.

@  ejguillot : (19 April 2020 - 02:33 PM)

Nobody posting? Why not?

@  ejguillot : (27 March 2020 - 05:19 PM)

Slowly working on a project GS... HP estimate for the parts going in the buils

01 October 2019 - 02:36 AM

Hi everyone,


It's been a long time since I posted, and longer than that since I started the project build on a 98 GS.  Today's topic: With the parts I'm putting on the engine build, what would you estimate WHP to be?


Pulley size: negotiable.

42lb injectors.  May upgrade to 60's and uprated fuel pump and run E85

180 degree thermostat

Intense Motorsport Stage 1X cam, stock rockers/pushrods/lifters

Ported heads with oversize valves (Bought these from Robert Moschella, who was once active here many years ago.)

Short stack intercooler (Bought that used years ago as well, I know that an full stack would be better)

Port matched LIM

Gen 3 blower, will do light porting to outlet, and port/polish intake

Northstar TB, LS series MAF (bought so long ago, will have to look up the part number), drawing from fenderwell CAI.

XSPower 3800 headers, dumping into Hogan Performance 2.5" single mandrel bent exhaust. (Maybe I should have gotten the 3" instead.)

Dynomax VT muffler.


Computer tune: Will have to be redone to match this setup.  For the purpose of this estimate, assume a proper tune. Redline to be set at 6200 RPM, until I can get a crank dampener that can handle higher.


Put your guesses below! From what I've read in this forum, should be at least 300WHP.
