Definitely more than a little. I bet this fan pulls 2.5x more air. I still think the radiator is a bit junky tho.
Can't tell. At 6500rpm and 11.1psi it is using a touch over 880lbs/hr. On engine dyno, same pulley, it made 920hp at 6300rpm and 15ish psi
That's what I have heard. However I'm assuming that the 4psi I am "loosing" is coming straight from intake air temp drop from adding the intercooler. I would bet my iat non intercooled were over 200f...now they are less than 120f for sure... Might be lower. When I had the engine on the dyno last year the larger pulley made 11-12psi and going from 24* to 26* picked up almost 50hp. I think with the 12psi of intercooled boost I'm making now, 20* is crazy low. I bet if I add timing my afr will lean out from 11.5 it is now, requiring more fuel.
You're likely bang on with the intercooler and charge drop. I assume your system will add fuel as AFR drops? But You're probably right about that too, probably a couple tenths up in AFR. With that intercooler and better fuel control you can probably get a degree or two more agressive on top too. Really spice it up.
I think you’re into plug reading territory. A blow thru will take a lot more timing than most anything else.
I don't think so. It's an 9.2:1 intercooled sbc on e85. I'm pulling almost 16* of timing for 11psi. I bet I end up at 26*. Blow thru is definitely better than non intercooled efi, but the intercooler on efi makes it close.
