GTM roll cage modifications and race car build log

[crash]

Not trying to be a Richard, but if JG or you are anywhere near a REAL Trans Am series car then the people running them haven't a clue. Those should be 900 HP with huge tires and great suspensions. I was talking with a friend that used to run the Trans Am series and was saying how we were very happy to be running 148 down a particular straight. His reply was "Let me know when you reach 187". That's a HUGE difference, and challenge cars are no where near our times out here. Again, not trying to be a jerk, and comparing to TA cars is fun(obviously I am doing it also) but they should be 10 seconds faster than a challenge car, easy.

Now the ARE stuff. Really all I use of theirs is the pan. I run a 3 stage Auto Verde pump with a separator. The low profile pans from ARE require a bit of modification for a supply line attachment. I have suggested to Gary that he change/update his castings as it would be very nice to not have to weld on a brand new cast pan to make it work, but last time I checked, he had not done this. You can get one of those long block adapters, but the fitting ends up below the pan and the lowest thing on the engine/trans combo. Not a real good thing for the oil supply line to the engine. Be careful/aware of developing too much vacuum. It can starve a piston of oil. Also, the number of stages does more than create vacuum, it also gets the oil out of the engine better so it helps with crank windage. Segmented pans are another way to go if you want to go with a 4 stage scavange pump. This just makes the pan like four separate little pans and prevents sloshing.

The ASA stuff uses a single stage pump and vacuum is not created in any substantial amount.

I'll look for some pictures of my components.

One of the things ARE has that is nice is a multi stage pump that bolts right to the A/C compressor block bosses. In my case I had to make a front engine plate to mount the pump, which was a hassle. ASA pump mounts this way also, and the Daley stuff doesn't need a mount as the pump is part of the pan.
