Default under the hood lately

Tonight plan was to change SC oil and put on a MAP TB heat shield I got used off a ILGPC member for $10 : SC oil change went fine, pumped out with hand soap dispenser, got most of it cause 2 bottles filled right up to bottom of threads. good.

Now the bad, when pulling off the rear TB bolt to slide in the heat shield, coolant leaked out, damn, gasket seal got broken with removal of 1 bolt. Good thing I had a extra gasket I bought for "just in cast" few weeks ago. Wasn't planing on removing the TB tonight but you gotta do what you gotta do. Tb shield looks nice though, finished by flashlight

Peace of mind Todd said, Thanks again Todd, I called and asked him a few questions, still tracking down the last of my misfires, the non platnium plugs took most of it away, and noticed some corrosion on the igntion coils, tonight I cleaned them up along with the boots. Kinda weird, I do only have 34K.

Something I noticed that the coils closest to the motor had the most corrosion, 6, 3 and 2. the furtest away coil 1 was totally clean, got progressivly worst as closet the the motor. Obviously a heat issue, and Todd pointed out the corrosion definitly would be causin slight misfires. Car drives fine just my gas pedal still would vibrate someone under heavy load and WOT considerable better after the plugs last weekend.

Took for a test drive after wards tonight and didn't feel any vibration Still need more time to tell but all is good so far

Planning on getting PCM changed to run 160 fan turn on and tstat soon. along with a 3.3 pulley for street along with Todd'* latest code.

Also got my Michelin Pilot Sport A/* tires on. dry traction is better, cornering is far better and the best is the wet traction, drives like it'* dry out.

All things combined I can just feel that 13 sec slip in my future on street tires.
Going to borrow a set of drag slicks off a ILGPC member for a track outing too, that should definitly have mid-high 13'* all over it.

Also forgot to metion that I got out to the ILGPC mod day this last saturday.
There were 2 header installs 1 TOG 1 SLP, a stage 4 blower swap running a 2.7 pulley, he'* the 2nd fastest in our club runs 12.6 I believe took me for a nice ride afterwards Also watched our ILGPC intercooler get installed, learned a fair amount and had a cold one in my hand the whole time. Lots of grilling going on and horse power in the air.

The house owner Steve BumpinGTP on club GP went for a little ride around the block inj his toatally not street legal GTP. Were pretty sure he has EVERY Intense part and I do mean every, he has no exhaust just header dump, and still had his M/T slicks on, car is a trailer queen, no interior at all other than driver seat. He just got it back early in the week for some final tunign done, expection low 12'* high 11'* at GPG this weekend.

Was fun and learned a lot. Recomend everyone here to find your local grand prix club and join up, go to some events, they won't rip on you too bad for having a Bonneville.

Sounds like your heading for 13'* bud

I've heard about the Ilcgp cooler, nice are they? How long did the install take and how can you get one?

Glad I could help Taylor. Good to hear your vibration is gone but I would stlil look at replacing those taylor wires. So Steve got his motor back together? Last time I saw him was at Pontiac Nationals when he spun a bearing.

I'll agree with that. But here in MN we want to have our own events instead of mooching off the GP guys all the time.

Sure easy to make, but for 10 bucks not worth the hassle to me to make my own

ILGPC intercooler couldn't find a link for it, don't think there is one yet, have to contact the right folks if you want one for now Think they will be sold through a vender but waiting for the 25ish cars that have them to use them for a season, so far only 3 failures that I know of. Already on 2nd version after first 10 cars. They come color anodized in your choice and choice of plumbing and core. all for UNDER $1000 to local members. Just the cooler itself is 550 I believe if you want to find your own plumbing and radiator.
There'* one mod day a year at the machine shop that makes them, got to take a little tour back in July.

only pic of one I got of one Can you tell we hit it off right away.


Looking like next Friday I might be able to get to the track, hopefully can skate out of work a bit early, no slicks planned for this event. Just some 100 octane and 3.2 for track. Going to use my free rain-out pass I got last fall too

Oh forgot to add, Today car felt stonger than ever and had NO vibration at all
Had fair amount of WOT in today and am SO ready for the track now. Get'* me thinking my 14.1 at B-fest was still with moderate misfires, I can remember feeling it in top of 1st and 2nd cause Todd and I were discusing it that day and I was looking for it. It'* been like that for almost 2 months getting progressivly worse till the problem was finally fixed over the last couple of days.

My work is moving over next 2-3 weeks and life will be hetic, Don't mind the extra work but downfall of the move is that my commute is will be 50min with no traffic (start at 6am) and 1.5 ride home in traffic. compared to my 15min both way now BUT the plus side is that Byron race track will only be 25minutes away. might be visting often once work is back up and running smoothly. Pretty sure they stay open till 1st snowfall.
