Has anyone replaced the flat mirror glass on the "Hippo" mirrors with convex glass? (I have round dots on them but I don't like them). Internet search for convex mirror glass has come up short.

Does anyone have any idea why GM built the cranking spark chart in the manner shown below? Note the rather significant changes once the engine reaches 212 degrees and the 100 to 450 RPM range? This is the stock table from the GM LS3/480 ECU.

I was posting on the Graz Starter post in the other area, but felt this merits its own special post. Many have expressed issues with the Bosch starter for the Graz, and like many, I have checked the aftermarket for a better starter that would fit the Graz......no one makes one. Last Sunday I...

For those who used the Vintage Air system supplied with the car, how good id your working in AC mode? How many pounds of 134 did you use? I've done all the typical system pressure checks, swapped out the orifice tube, ran dye and see no leaks (I replaced the expansion valve for room). The...

I have watched a lot of video's with a ton of ways to remove minor scratches from plexiglass/acrylic/poly but none have worked on our scratch resistant poly side windows. Has anyone discovered a trick to minimize even remove a scratch? Thanks

I'm using the 2004-2007 Cadillac alternator 150AMP (GM 84009383). I'm having an issue (electrical is not my strength), but the volt meter in the cockpit will at time show a strong 14 volts then fall to about 12.5 volts and then migrate back up to about 13.5 or so (as best I can read the volt...

Most of us probably have the original Centroid fuel level sender in the tank. I believe the unit we have has continuous output of 2.33V empty and 0.54V full. My fuel gauge is based on ohms (240 empty and 33 full). 240/33 is the factory default setting from Speedhut for the fuel gauge (it is...

Gents Without the body on, there are a lot of reference points to complete a string alignment for toe. Just looking to see what anyone is using to square up the reference lines once the body is on.....aka what reference point are you using to square things up?

I have a puck that is leaking. Cant find anything on the web on repairing the leaks. I have the repair kit, but cant get it apart. Anyone ever disassembled the ram? It has 3 rings, center ring extends with air/hydraulics. Inner ring has two holes suggesting it may thread from the outer...

This subject may be too involved for the forum, but I thought it might be a good idea to share some knowledge about the tuning process, so I have put this together to get a dialogue started. It may go nowhere, or we may learn a lot from the more experienced among us. I’ve chose like so many, the...

1. Is there a best/correct way to adjust the original shifter and the Graz tranny? I see there is an alignment hole at the tranny linkage but not certain the best way to use it, if at all, with the stock shifter? 2. I can only get back into first gear after I stop the car (aka it won't...

If anyone has an LS3/480 tune they think is really good, if your willing and able I would like to compare it to the one I have. I have the HP tuner tools and software and would appreciate anyone sharing if willing. I'm having a random stall issue that's new, but not sure where its at. Thanks

Gents, tried the net but no luck. If anyone took a snap shot or captured the GM stock throttle table in the engine controller, would mind sharing it with me. It’s a long story, but seeing it will give me confirmation on an issue I’m experiencing with the controller. Thanks

I haven't seen this one discussed so I just experienced a PO606 error code. IAW the internet it could be all kinds of stuff. Before I dig in, has anyone had this code and what did you do? Thanks

The stock starter for the Graz is the Bosch SR0408X. Its a refurbished unit built for Volkswagens from 1995 - 2006 for nothing more than a 1.9L engine. Has anyone found a stronger gear reduction unit or anything better than this unit?

OK, this is an odd question, but has anyone found a ready made car cover that fits over the SLC? I have a wing which is making it harder than usual. I have a couple oif car shows to attend and the cover will come in handy.

I know many of us are less than pleased with the standard shifter, but has anyone ever played with adjusting the internal parts? Looks like there is some opportunity to adjust its movement as it exits.

Gents After 4 tuners, it has dawned on me (a little slow I guess) that tuners are every bit as critical to our projects as hardware. I wanted to start this thread to share with all builders the good tuners we have found (so list yours as well). Tuners are typically local, unless they travel or...

Gents I discovered a leak at the fitting that feeds the fuel pump from the tank (the bottom one on the tank). What type of thread did RCR use on the tank, I don't see it in my notes anywhere? I'm hoping I used the right type of adapter thread into the tank. Thanks

I have a whopping 40 miles on the car. I’m struggling with getting into first and second on a downshift. Up shifts are fine. I have the old shifter so when I set my cables on the shifter arms of the Graz, I set the shifter in as neutral a position as it would allow and the transmission in...
