i measured 50 times hoping there was some way to fit the 2k under the hood with no luck.

its the 1800hp rated one, but i trust it to be a legit 1800hp rating and i dont plan on being close to that any time in the foreseeable future.

ncc fab had a few that looked like they would layout under the radiator core support i prob would have gone with if i didnt go this way

Yeah that 2000 is 1" taller than the 1800 and I figured the 1800 may require "massaging" but will be worth it. NCC has some nice looking stuff!! I feel like I've heard of them elsewhere on one of the many other forums. Pretty much hit the nail on the head, will run something horizontal under the radiator support.

going in the right direction
still using the a2a, weather was just a whole lot better. the only real change was i set up some limiting straps for the front end.
did a run without them just to see how much of a difference they made in the same weather. but first run it spun leaving and on 1>2 shift. was making a few more psi then usual with colder air.
so not too sure if it was the weather or the straps but it picked up a few tenths to the 1/8th, didnt 60' much better
Left lane on both

That intake top is pretty. I bet this beast breaks some hearts.

I have always wondered about these intake mounted inter coolers and whether the cylinders closest to the water intake would run cooler than the ones further away.

I can’t imagine there is a significant difference between inlet outlet with 1”+ fittings and the water flow being pumped through them. Just wouldn’t think that water has a lot of dwell time in there, but could be wrong.

when it does what its sposed to! still having 1>2 shift happen way before its supposed to on more than half of the passes. throttle body (dbw) was failing out for a while have swapped few a of them and have one that hasnt failed for a few weeks. its not quite ready to be competitive. needs actual boost control and a bump box. im just kind of playing with the 2step to see where the rpm needs to be to build enough boost to cut a decent light, but if someone double bulbs in usually needs another half sec or so to get up where i want it to leave on.

i havent put much thought into it, placement for an iat sensor in the lower manifold was about the extent of it. for what im doing its not that critical and will be tuning it conservatively, just going to do somewhat of a flow test and make sure its moving plenty of water through the circuit.

got it all back together, pulled the a2a intercooler out, remounted trans cooler and ran some new lines to it- since it shouldnt move for a while.
routed the hoses to put a chiller in up front, tied them together so i could put some water in the loop, check for leaks, see how the davies craig pump flowed. need to grab a grommet/chase nipple probably to pass hose thru that plate.
need to finish some wiring for the intercooler pump and new temp sensor in the lower manifold, and big fuel pump is just constantly running- need to look at that also

So I am going to ask what a lot of folks probably are wondering...
Why?
You went to great lengths, and expense, to build a 7 second combo, and then slowed it all the way down into a mid 10 ride by installing it into a 3 ton vehicle.
I mean, if speed is that important to you, then why did you put all that effort into a school bus?
If speed isn't that important, then why did you put all that effort into building that engine/drivetrain combo?

Because building a 7 second combo isn't nearly as streetable or as comfortable as a 1K whp luxury SUV you can literally drive anywhere, cross country, etc?

Count me out as one of the ones (I doubt that there are many ie you may be the only one) who is wondering why the op would do such a thing.

I would say, why not? I think more people will be intrigued than wonder why.

Uh.....think you missed my point completely.
That very engine, trans, etc, could have been put into a much lighter vehicle, still be completely streetable, and be way faster then the school bus he put it in.
He obviously has a lot of resources, so if he wants to spend a ton of it on such a project, well then, to each his own.
But for the money spent, he could have been a lot faster.
Or, saved a ton o-money, and have a 12 second luxory suv, which is still way faster then most out there.

/\ pretty much...no good answer for ya. the heart wants what the heart wants lol

its obviously snowballed a bit, cost of the dart wasnt much more than an stroker ls3 (needing a block). working on this junk myself it got to the point where i was sick of pulling the engine and trans every couple months to fix/refresh. so just made the leap to a fairly bulletproof drivetrain that i could get a few years out of, hopefully. not really like i wasted money, most of it can get pulled and thrown into something more appropriate if i get sick of it.
