What do *I* know from TPI specs? The question was..."Does anyone know where to look up the torque specs for the runners to manifold and to the plenum bolts. I answered the question directly, positively, and correctly. I didn't hem and haw about my opinion of the tightness, waste space speculating on the units of torque the spec may use, or even make a potentially misleading stab in the dark at a number I didn't know. I answered what was asked, directly and factually. Climb all over the TPI owner that answered first, not the poor Crossfire guy.

RACE ON!!!

Default Sorry Sir

It was not my intention ever to step on anyones toes or anything like that. And if I offended anyone that was NEVER my intention. I am truly sorry if I did. I replied to the gentleman rhat replied to me saying he would post the info asap. And Im sure he will. When I reposted to bring the thread back to the top thinking mabe this would make the topic more visible to someone else that happened to visit. Again Im sorry if you or anyone was offended by this.

YOU didn't step on MY toes. *I* answered the question you asked. Afterward you said that you had been looking for a chart. 85C4fanatic said he would post them later, when they were available to him. Great. Then there was a ration of garbage directed at me, not by you, but by someone in the peanut gallery with less help to offer you, than the first responder, who only offered post count expanding nonsense.

you think I care about post counts? Please note I posted the correct number.

I will take one dig, I deserved it, the 2nd was totally uncalled for.

Except for lower intake manifold bolts to the heads,I never torqued the TPI system with a torque wrench.I used my wrist method.Mainly I tightened a bolt criss cross til theyre snug and then when I cant turn with my wrist anymore I go to another.I use a 3/8 ratchet and torx bit for this method,and some extensions if called for.I hold the ratchet close to the head or around the head and turn til its tight and move on.When thats all done,I use check each sides one by one and see if they need a little more.
Using a stubby ratchet is great as well...most of these areas require less than 20 ft lbs and some of the bolts are impossible to torque to specs correctly with extensions and different size sockets,so I do it until it feels medium like tight,and not over doing it where youd hear a bolt creak or screech inside the hole.

This has never failed me on any cars...even alot of other GM intake manifolds Ive done,Ive tightened things down this way and never had leaks or problems.

This may take alot of practice,but its what I do in areas that is realistically dumb to try and torque bolts down where you cant even use a torque wrench in there.The ft lbs are usually low enough that you can get away with tightening by hand/wrist and never have leaks.
