attn mini-ram owners
I figured I should post this here as well as in the C4tech area.
the thermostat mounting area in my mini-ram is the same depth as the thermostat I got from TPIS (170deg). this does not give my thermostat any room to open up when at operating temp. the stat has a brass cylinder that moves with the valve and makes it longer when open.
lenghts:
mounting surface to end of stat(closed): 1inch
mounting surface to end of stat(open): 1 and 5/16 inch
mounting surface to bottom of intake : 1 and 1/16 inch maybe
hopefully I can find a shorter thermostat tomorrow. will let you know if I do.

Re: attn mini-ram owners (ol,RJ)
the problem is solved. though it could have been easier.
I found a thermostat that can work but is the wrong temp. so I swapped the spring and valve from the old one. the one I found was at AutoZone
part # 403-192
the 192 is the temp of the stat. it is raised up from the mounting surface 3/16 or so. you may be able to order one in the proper temp for your miniram, but I am uncertian about it.
here is a pic of the new and old stat. http://www.corvetteforum.net/c4/olrj/pictures/m28.jpg
new one on left . the old one is a little bent from my swapping springs.
you can see the way the new one has a step that raises it from the intake.
I have it all back together now (with 4 bypass holes 3/16 dia in the stat). she runs nice and cool now
179 to 190 idleing in the garage.
happy happy joy joy

Re: attn mini-ram owners (89vette)
89vette,
could very well be the problem. if you take it apart and can't push it open with a screwdriver while its in the intake, you'll know for sure.
I'd still use some bypass holes in the thermostat because even with the raised one I don't think it can open all the way up. it sure is a improvement though, I have 130miles on the 406ci now and the highest temp was 201deg but most of the time its in the 185 to 190 range while driving.
good luck

Re: attn mini-ram owners (ol,RJ)
I ditched the minram. I didn't like the way it ran and looked. I'm almost complete with the Super Ram intake install. Your findings are just another check mark as to why I hate the MR.
Do you have any tip in problems with your car?

Re: attn mini-ram owners (89vette)
tip in problems, yes. but I can't say much of anything for sure yet. I've only driven it 3 times and I think some more prom mod's are needed. its running rich in the low rpm's for sure. I need to find a cheap laptop and do some recording. (I can't believe how hard it is to find a older cheap laptop).
I have heard some people bring up a tip in problem with the mini-ram.
Any Ideas about why this is happening on mini-rams???
I take it you got tired of chasing the tip in problem.
(I'm just quessing since I'm new to fuel injection),but it seems to be a lack of fuel for a split second, sorta like a bad accelerator pump on a carb..
surely there is some extra fuel injected when the TPS shows movment????
