Some of us have 93 (Yay PA) but a number of areas only have 91.

 

then some people should either get methanol injection or just not mod their car

18* is fairly conservative. I'd still check the h/e pump to see if that hasnt stopped working. You never did mention what your IAT2 was before/after a pull.

 

No my pump is functioning well. I clearly see the coolant flow in my reservoir. My IAT2s get from 90F to 130F during a pull until the end of third gear. During a hotter day, they get to 140F, when its 80F outside.

A phenolic spacer is coming this week... I expect it to greatly reduce the IAT2s. We will see, I will keep everyone posted!

 

meth would cool it off good, but with the no knock in 2nd, but in 3rd it has to deal with the load of the engine being greater in 3rd compared to 2nd.

 

^^yes.

and those iat2 temps arent bad for a 2.7 pulley w/o meth. you may just need a little more fuel in the upper rpms.

Meth and a tune will make a world of difference though.
