  1. One of the last updates. Got a K&N filter. Cleaned up and painted the IDI cover. Also snagged some factory tweeters for my car from the junk yard. Had to repaint the trim piece but well worth it. Lastly, Trans Am exhaust tips. Looking to hit the dyno this coming week then a professional photo shoot.
  2. Well some update. Got that damn torque strut mount in, although it was meant for a jbody. Had to hack up one end a bit but its in. Now for the transmission mounts. I had purchased some from Turbo Tech Racing (which again are intended for a jbody) and sure as it is.... The jbody mounts (although the same platform) are indeed different from mine. The journey begins. This first pic here is a comparison. The one with yellow on it is mine. Notice how the casting is different and the insert is much smaller than the jbody. You can really see the size difference in picture number two. After looking at them both for a half hour, I concluded it should fit. All bolt points meet at the same distance. So I am here to tell you YES a jbody front mount will work for our cars. This is where I got a little upset. I was hoping the rear mount would be the same case... Nope. Look closely in this pic. Again mine is the smaller one. Not only is the insert smaller, but all the bolt down areas are NOT at the same distance. The jbody mount is longer. I was able to use the front TTR mount. I cant not use the 2nd one. I cant return it as the two sold as one item, and I am not about to try and have this poly machined down to fit my mount bracket. After much much MUCH deliberation... I decided to install the jbody mount. There was about 1/2 inch distance from the insert holes and I know there is some play in the mount bracket on the frame of the car so I decided to try it. TEST FITTING ALONE took me almost 2 hours. Wanting to reassure myself this could work. Then pulled it back out, swapped inserts, then about 2 hours again getting this thing to fit. Ladies and gentlemen, the cast iron mount for our cars and the jbody is indeed different. BUT, it will fit. With enough time, energy, patience, and tools, it can be made to fit. And the car drives great with it. The car feels great. Dash rattles like no other, I feel the car KICK every time the starter makes a rotation, but no more slug. This puppy is not moving lol.
  3. Yeah the LD9 (2.4 twin cam) is actually rated at 150hp which is about 128hp to the wheels. I hope to dyno 230hp quite simply thats pretty much a gain of 100hp to this motor with no internal mods, and twice the power the m45 supercharger was to put out. But yes 215whp is like 240 at the crank. If I got my target of 230whp Id be around 260-270hp I think. There are calculators online for that but you get the idea. Actually now that I think about it GTPs dyno at 200hp stock when rated at 240hp. If I dyno 215 it would be more than 240hp. Sweet. Lol.
  4. Oh definitely not lol. Even if my motor was built built, even with/for the supercharger setup, would be lucky to see past 300hp. But my high hope and goal is to see 230hp after tuned but I doubt it. Realistically... I bet 210-215hp.
  5. Oh Im not sure bro lol. The nozzle was threaded. So I just took it to home depot, looked for a fitting that screwed into it andmade sure the other end was big enough to fill the hole already in my intake that was designed for pcv. But thanks guys. Mounts, then dyno time.
  6. Meth kit installed and working off the MAP sensor.
  7. Overdrive crank pulley installed. Im sure the supercharger is now pushed to its limit. Probably seeing 12psi on stock motor. Faster? No idea. Afraid to floor it. Meth still in trunk. After thats hooked up, dyno time.
  8. So far no knock. I was running high octane though. I think after this is installed Ill be seeing around 12psi total.
  9. Picked up a OD crank pulley. For those of you who dont know what it does, its bigger than the stock crank pulley, but the revolutions do not change. This will make all the other accessories spin faster. The alternator, compressor, idler, tensioner, and the supercharger. Should be seeing about 3psi more with that. Then I install the meth kit. Then the dyno. Also think I figured out why the car is slower than it should be and why it feels like its dragging. I have too much advanced timing. Like 10 degrees too much. Need to adjust that on the dyno too.
  10. Well, I am not happy with my times. Went to Speedworld last night. Wasnt sure the supercharger swap would make a difference but there are I have seen different results. First off, here are my best 2 times at the track. Reaction- .7135 60ft- 2.1897 330ft- 6.4506 1/8et- 9.8994 1/8mph-72.87 1/4et- 15.2404 1/4mph- 91.93 Reaction-. 5779 60ft- 2.2174 330ft- 6.4608 1/8et- 9.8903 1/8mph- 73.12 1/4et- 15.2297 1/4mph- 91.59 After these I think something broke. Engine is fine. I think the trans is fine, but the wheels (I beleive, maybe just one) want to wonder. I was flying down the track in 3rd gear and all of a sudden it just started curving right. I jerked the wheel back and got the car going straight and after that I called it a night. Long drive back noticing it a bit on the freeway, I dont know what it is. Tie rod? Hub bearing? Meh. Scanned my car with HPTuners. Timing is between 22-29 degrees max at WOT, with xylene in my gas tank no KR, and my AFR is between 11.1-11.5 at WOT. Which is amazing since this is the original tune I had for the old m45 setup with stock pulley and no header. The biggest difference I noticed. Old setup reached 201 degrees intake air temperature. With this setup, highest was 164 degrees. Awesome! This manifold design is better for sure. Anyways, so thats where Im at. Next, fix the problem whatever it is. Get a larger crank pulley, throw in the meth, hit the dyno. Here is a video racing my buddies 04 GTP on the way to Speedworld, and then a video actually running at Speedworld. My buddy swapped his pulley from a 3.6 to 3.5 and I had an extra passenger so yeah. I knew I would lose. Enjoy.
  11. Got the video. My buddy doesnt have video editing program so its a long clip. We left a car show and hit the freeway. Raced a few times but the only one where you can really see me is at 2:40. Hope this will do fellas. His car is a 2004 Grand Prix GTP 3.6 pulley, headers, full exhaust, overkill pcm, wai, and all the other little things. Suspension, plugs, blah blah. http://www.youtube.com/watch?v=cmaUj-psciU&feature=youtu.be
  12. I agree. But I dont want to end up with wheels that look like they are worth more than the car. Plus Ive ran into options but I HATE multi lug patterns. These wheels I have are only 5x100 and I like it that way. I also like the color of the wheels. They arent exactly black. They happen to be the same color as my GT badges too. Lame excuse to fight for I know but I admire the accent matching.
  13. My wheel size is 17x7. Same as the 17" on a Cobalt SS. Unless you are suggesting the 18" wheels that are 7.5 wide but Im not interested in hot roddin 18s on this car. So what do you mean, thicker rim?
  14. Thanks fellas. It means a lot to me. No numbers, but I just raced my buddy with a 3.6 pulley, headers, cai and other little things on his 04 GTP. Dead even. Went from 60mph to just over 100mph. That made my night. He got it on video, dont know how good though. Hopefully I can show that soon.
  15. Most of you know me. Its just been a really long time. Took the car apart, decided to put it back together. I searched for this specific car in 2005 on autotrader. Found 1 in a 300 mile search. Like 286 miles away, California. I drove out there and got it. Just cant let her go. Put way too much money into this thing. But oh well. Here she is when I first got her. Now... M45 Supercharger HPTuned Long Tube Header w/ 3" collector High Flow Catalytic Converter Full 2.5" exhaust GM Crossflow Muffler WAI Gunmetal Exel Wheels Black Housing Headlights GM Strut Tower Bar TenzoR Lowering Springs Here is a video when I had stock pulley and just 2.25" catback exhaust. [media]http://www.youtube.com/watch?v=FEmTpVgdqf0 Stock I ran 16.7 at I dont know 78mph? Lol. Supercharger 15.6 at 87mph maybe. Now 15.4 at 90mph. Times will improve once I get some mounts and traction. Possibly picking up a meth kit next. Go to my youtube page http://www.youtube.c...rcraigbwilliams and see my video running at Speedworld Raceway. Subscribe, like, whatever you want. Also got a whole set of drag radials. Why? Because I can. And I like to match. 225/45/17 BFG G-Force T/A drag radials. Well here is the fun part. This IS super rare. Supposedly 1 of 5 made. These were the first prototype M45s GM was building for the LD9. Originally they had planned to intercool it but came to the conclusion there was not enough room and that the supercharger can still be as effective and efficient without it. And to save trouble and money, they casted the manifold and supercharger all as one piece. The pulley is somewhere between a 2.5 and 2.6 and should boost up to 9lbs. What is the advantage to this supercharger? Well I for one like the fact that it is now mine and no one can have it, and its not an option for anyone out there either. It leaves a slim window open for the possibility of intercooling it. And lastly I believe the manifold may be a better design considering this supercharger sounds different. Sounds more like an M62, maybe an M90. Must be higher flowing. I have not full throttled this thing because it scares me. Maybe when I get some race gas back in the car and turn on the wideband and see where the afr is at. Still need the meth kit hooked up too. I took a picture of every possible angle. You can see how it mounts, how the brackets are different, even the idler is different. The pulley has the protective wall helping keep the belt wrapped. Also, the fact the throttle body bolts to an adapter that bolts to the supercharger, leaves an option for a much larger inlet. Everything had to be gasket sealed since GM didnt design any gaskets for this kit.
  16. I would love to see that BS. Quite simply... No. Might as well go finance a brand new car with warranty and all the goods. Cuz thats what you will be paying in the end. How about instead of buying the engine cuz its a good deal, you buy an engine that WILL fit thats a good deal? Look up 3400/3500 swap info.
  17. Thats what I said. But he refers to his engine more than once as a 2.4 Twin Cam and most people who have the Twin Cam like to refer to it as a Quad4... Except he actually has a Quad4 but keeps refering to it as a Twin Cam. So I dont know if there is a story I am missing or something. Engine could have been swapped in, who knows. Or someone put the wrong ignition cover on lol. Yes Quad4forums is where its at for this. Im on there too lol. Its been a while.
  18. Alright kids. First off, GM is not building the supercharger kit for the LD9 anymore, but some dealers still have some kits on the shelf. Part number is 12498660. Call a dealer and find out who may still have them. Or search online. They are cheap now. Here is a video on mine when I had the kit on. Next, 3800 swapping... I will tell you first hand that if you need to ask yourself about it, then its a flat out NO. You need to swap the whole front end of the 3800 car pretty much. Yes a wiring nightmare. Welding will be involved too. It would be a project car and no longer a reliable daily driven car. Lastly, if your car is a 95, well then the supercharger kit wouldnt even work. Your manifold is a different pattern than the LD9. If you have a 95 it should be a quad4 motor. Yes there is a difference. And those cant be tuned you have to get a chip or stand alone, all this crap to make a boost application work. So if you have the Quad4 your best option is to have the motor built. Or swap in a W41 if you can find one. Thats the HIGH OUTPUT Quad4 motor. Or get custom with a turbo kit. But first thing is first. What engine do you have? The 2.3 Quad4, or 2.4 Twin Cam?
  19. ^^^Yes what he posted. Except Im not using a electronic throttle body. I got a Northstar throttle body attached to it. Thats a 75mm inlet. The difference in the cylinder heads is the valves are bigger and I believe the rods are stronger.
