Turbo Dyno numbers inside !!
#41
this is parish8, i think the 78psi of fuel presure isn't too high, if the base presure at idle is 58psi his presure with no line to the reg is probably 64 or so, then add for 14psi and that is right where he would want to be, 78
i am not at home and on a buddys pc so i haven't looked at the logs but the most IAT rise i ever see on a 11+sec wot run is 30deg, if your seeing 50deg i think something is wrong with your pump. i adjusted my iat vs timing table way up and put both my low nad high octane tables the same and still i see my timing go down with higher iat's, i have an old version of edit so maybe there is another table.
nice numbers for your first run, i am prety sure i will get 600+ my next trip to the dyno, i want to see you hit 700

I think it's Definatly the heat causing the timing loss for sure
Makes total sense
i gotta looking the pump i think i might have an air pocket or something
I was driving it today and felt the intercooler and it was hot felt the heat exchanger and it was maybe at the most little over ambient
If it stops raining here I'm gonna get that fuel cell in for some extra water holding
btw i maxed the maff at 4600rpms and my tps was at 70% or so
I'll show you my logs when you get back
hhmm pulling 21 dgrees of timing with the heat
wondering what that does when i get it sorted out

Parish, go home and put on the 28" ET Streets and get some 10.8s.
I cant wait to see a truck hit 1.5s in the 60'.

Parishes cam and Skis cam both sound mild, even with massive lift. My cam is 218/229 113 .560. So with such a wide over lap should it lope alot? I realy dont know much in this area.
