    All I've done is add the K+N air filter and added a pin stripe. The car is powerful enough for me and I don't want to spend any more money!

    So far 180 degree thermostat, 3.5 pulley, Thrasher CAI, a pair of Vortex high flow mufflers, Saner rear sway bar and end links, Super Plasma head light bulbs, close as I could get to HID without spending $700.00.And composite throttle body spacer. I have on order stage 2 MAF and adjustable fuel pressure regulator from RAT.

    I am waiting for someone to experiment with the SAE computer modifications, I want one but don't want to be the first to try it. Also am thinking about a shift kit.

    Thats all for now!

    I've got tons of questions on your lighting: I'd love to go HID because illumination is very important to me (I consider it a key safety feature and, besides, the Xenon blue tint looks sharp!).... What made you go with the Sylvania cool blue and had you considered a HID conversion? or did you consider, like me, that the cost was just too prohibitive? I've heard that the PIAA plasma super white bulb is good (better be at $85 US/pr.) but I didn't see Sylvanias at the local mod shop - are they any good (in your opinion)?

    Dan
  • The Sylvania Cool Blue's were the only ones I could find at the time. I just replaced my fog light bulbs with Plasmablue 893's. I got them cheap from E-Bay. I also got a pair for my wife's Toyota Solara Convertable and they look better than my Cool Blues. I think you can search E-bay for plasmablue and find the seller. He has a web site but gets 69.00 a pair on his site. I got mine for 12.00 a pair by auction.

    To those whose aspirations are to mod their Bonnie to the max, here's a web site that will aid you (us)in that direction:


    http://gaugepods.com/


    they provide custom A-pillar gauge mounts just as long as they get 20 or more advance orders. The prices seem pretty reasonable. Although I'd like to know what extra gauges would go on those pillars.


    FYI

  • jperdochjperdoch Posts: 2
    These 2 things seem like the hot setup for some better performance with minimal mods.

    Do you know if K&N makes an airfilter for a 2001 ? Also, are the flowmaster mufflers bolt-on or do they require adapters ?

    Any warrenty implications here ?

    Thanks.
  • smfransmfran Posts: 432
    I have the K+N for a 2000 SSEi. I don't see any reason why it would not be the same one for a 2001.

    Stephen-

    Regarding the K&N filter, I had seen in a previous post that the part to use was a K&N E-0940. I checked one out at the local Autozone store. It's a cone shaped filter. Now, when I look at the filter in my car, I don't see any way to get the K&N in there. I thought that maybe the existing square filter housing would just be removed & a short adapter put between the hose & filter, but then I noticed a good sized bundle of wires going into the air filter box. So, It doesn't look like the box can be tampered with.

    How did you fit the K&N on your car? Is the E-0940 cone filter the one to use?

    Inputs from anyone who has done this are appreciated. Pictures would be a bonus. Thanks!
  • rb8225rb8225 Posts: 33
    Now that I think about it, the bundle of wires heading into the air intake box is probably for the PCM, located there for cooling. Is this true?
  • smfransmfran Posts: 432
    The part # is MM33-2086 and is an easy rectangular drop in replacement; no modifications necessary.
  • homer2000sseihomer2000ssei Posts: 159
    thats what i went with , the dropin rectangle filter. What a pain in the [non-permissible content removed] that is too - to do it comfortably - you are required to remove the rubber air flow hose so you can back the cover off the air box far enough. D'OH. Until you do that - say goodbye to skin on your knuckles.

    I also thought about the cone - but am interested in what to do with those wires in the box?
  • I have a 1992 SE, with a K&N E-0940 cone filter installed. That bundle of wires is the temperature sensor, I believe. I removed the whole airbox and took the sensor out and attached it so it is right outside the cone. The cone, BTW, connects right to the tube. The tube pops right into the cone (take out the little metal tightening thingymajig first though) and you have a K&N. I have noticed a tad more power, remember mine is the base 170hp SE so it doesn't do a whole lot of difference. But 50-80 pull (2nd gear) has really improved. This summer I am going to make a ram-air setup, and take the intake tube out of a GTP (where the sensor goes directly into the tube).

    Stephen-

      Thanks for the correct part number. Now, I just need to find it around here. I may have to buy it online.

      Dennis- Your right about the enclosure being tight. When I was checking it out to see if the cone would fit, I wondered how to even get the drop-in filter in there without messing it up.

      It's too bad Thrasher doesn't make a unit for the Bonneville like they do for the GTP. I wonder how close the GTP version would be to fitting into the Bonneville?

    I have a Jacobs coil pack with their plug wires and a K&N filter. I paid about $270 for the whole package from them http://www.jacobselectronics.com .


    My K&N is the rectangular drop in. I thought about the cone, but was afraid of degrading performance in summer from sucking hot engine compartment air.


    Please let me know how the GTP intake mod goes.


    Also, where do you get the pulleys for the supercharger?

  • rb8225rb8225 Posts: 33
    Travis-

       Thrasher also has a modified pulley and remover/installer tool. You can see it here: http://www.thrasher-ep.com/store_ham/store.shtm

      There is also a Magnuson Nose Drive kit; you can find it here:
    http://www.grandprixstore.com/ and they offer a choice of pulley sizes. Personally, I would love to do the pulley mod but am afraid of the warranty issues right now.

  • rb8225rb8225 Posts: 33
    I was thinking about the recent messages about changing pulley sizes, & I started to wonder how GM came up with the size of pulley (3.8 inch?) used on the stock supercharged engine. Probably the best mix of power, fuel economy and emissions, but I wonder what the deciding factor was. Anyone have any idea of the rational for that particular choice?
    Also, what are the downside effects of changing to a smaller pulley? Other than possible warranty issues? Does the gas mileage get real bad? Can't keep the car under the speed limit & the tickets start piling up? Failed the emissions test?
  • refinerrefiner Posts: 59
    Ordered the Other Guys headers last week. Also talked to ASE chips. Their running a special next week. Instead of $539.00 to reprogram the PCM its $399.00. Hopefully I can ship it out Tuesday and have it back on Friday. Bye Bye speed limiter. Time to start looking for some Z rated tires. They claim a 20 to 30% gain in horsepower.
  • snicklesnickle Posts: 147
    Intense and dmckeown(in his late bonnie) used the Thrahser CAI. Look back in the archives, there should be directions. I have been trying to build one myself custom fit. Just have not had the time.
  • swblumeswblume Posts: 4
    Does anyone know if there's any exhaust headers available for the series 1 3.8L S/C engine? The closest things I've seen were on Grand Prix sites, and I know that that's a different engine than the one in my car...
  • sixxersixxer Posts: 36
    I recently picked up a 2000 Bonneville SE loaded. It's pretty much an SSE actually considering what it has. Anyhow, to the point. I'm trying to find some aftermarket parts for it. The first things I plan on doing is tinting it (this Monday, suggestions for tint levels?), a CAI (eyeing the GP one from SLP, it might fit), add dual exhaust (any suggestions?), and I'd like to drop it an inch or two. Anyone seen anything to give me a hand? The CAI I might be able to rig up myself as I did on my last car, just have to figure out where to put the PCM so it is protected. Anyhow, if anyone has any suggestions or ideas as to where to start, let me know!

    Thanks,
    Stan
  • I can only offer a bit of help . . . because the car is "non-threatening" to the police, you can likely get away with a darker than legal tint. I have the rear window and two back windows done darker than the fronts - -i stayed legal.

    there is a guy I know from the grand prix club in Toronto who owns a tint detail shop and would likely do a good job. also , he loves the GP's and appreciates the Bonne's as well. he isnt the cheapest guy around - but he uses top quality stuff . . . if interested - i can send you his email and name . . . i think his shop is in the north end of the city, I havent been there, but thats what my memory says - ill check if you want.

    as for CAI, i belive thrasher makes a kit that fits our cars, but going custom is a pretty simple idea. im having mine out in this weekend (crosses fingers) and its pretty straight forward. The difference in mine is that the guy uses a 4" dia. truck exhaust pipe that is bent at the shop. It is heavy duty and easily painable, (ive done mine black). its is attached to 4X3 rubber coupling on one end, (home depot) and the sensor just plugs into a small hole drilled into it. cone on the other end. PCM will get wiretied outta the way. Im going to use some heat wrap on the exhaust crossover pipe to help reduce the amount of heat in that area, and change the tstat to a 180.

  • refinerrefiner Posts: 59
    You sure were right about the dipstick tube being in the way of the header connection. didn't break it but went ahead and ordered the Grand Prix tube. That will get it out of the way won't it?Thanks Matt
  • kzmkzm Posts: 55
    I have the JET PCM on my car along with a K&N drop-in! When I turn the JET on, the "service engine soon" light comes on. I had the code checked and it was "P0107 MAP/BARO Pressure Circuit Low Input" translated: MAP Sensor Circuit Low Voltage. Fortunately, when I turn it off, the light resets. Costs too much to remove and send back and then install again. So, as long as it's not causing any harm, I'll deal with it. I wish I could confirm the HP gains advertised by JET.
  • sixxersixxer Posts: 36
    G'day again!


    Thanks for the tinting place offer but I already have an appointment made for Monday here in town. I'll just stick with it.


    Will the PCM be ok just tied out of the way then? I was just concerned about water and such when driving in the rain. I figured it was put in the box to protect it from the weather. They can be pretty hardy though I know. The air intake could be quite simple for me to do then. I already have a large K&N cone, 3" copper pipe, and a 4x3 rubber reducer from my CAI on my last car :)


    Also, I just got back an e-mail from Superchips. They are making a Micro-Tuner that will work on the 3.8L Bonneville. They said to expect it in a couple of months!


    http://www.superchips.com/domestic.htm

  • Well, yea - -Im thinking you are not driving to T.O for tint . . .:)
    A little knowledge is a dangerous thing my friend, and I have so little I am practically a one man wrecking machine!

    I supose, if the pcm gets wet there, and Im not sure it would be bad, it could be wrapped in a plastic bag or similar..

    Ive got 2 winters under my hood, and havent noticed much in the way of dirt (I do clean it a lot though). My guess is the light assy keeps it protected.
  • rb8225rb8225 Posts: 33
    Sixxer-

    I've always had the understanding that the PCM is in the air intake for cooling purposes. Otherwise they could have put it many other places that were protected. The air intake location will get a lot of airflow over the PCM box. If it is out in the open it may not get enough airflow to cool it properly. I wish there were some GM powertrain engineers lurking here that could provide some insight.
