WINTER IS COMMING

I have the gage installed temporarily, looks like Medusa's cousin is sitting on my dash, I'll get a more permanent solution built later.

Last night was upper 20'sf ambant.
68-76°compressor outlet temp @8-15psi boost.
113° peek compressor outlet temp. 81° rise
31-32°IAT at anything less than hard acceleration (not wot)
27°f under compression braking
41° peek IAT @25 mph( insufficient Ram Air) 8%hill ( medium to heavy engine loading) 3gear
312- 790° f EGT

----

Fully warmed up
Med throttle 8% grade 6th gear(.61 OD) 50mph 1150rpm 20 psi top1/3 radiator (above IC) blocked
Peek recall

EGT1- 860° @ standerd sopt in the manifold
CHT1-168° colent temp @radiator outlet
CHT2- 118° IAT @head post IC
CHT3- 258° charge air temp @compressor elbow..

Ive seen as high as 310° charge air temp @95mph 25psi boost the ic is suited to handle this for no more than 60sec. IAT's quickly rise to 120° w/55° ambient that is 7% loss of power w/same fuel delivery rate due to thermal expansion reducing 02 volume. Conversely last night showed it'sway too big for winter
