Intercooler options for Drag Only
I dont think the OP has a truck intake, it was the other needle dick in the thread. But agree for 850hp damn near anything works.

I believe A2W has least restriction. I’m runing
a sniper intake as the truck manifold hit the firewall. If I can keep the water at ambient it should outperform air to air. E85 is a pita to get north of the 49th parallel and I don’t want to go methanol or spray it if I don’t have to right now anyway. If the rad idea won’t or doesn’t work I’ll put a cooler in the rear.

No cooler has the least restriction.
After that, the best designed system has the least restriction.

I don't imagine with that set up you are really worried about adding a few pounds. So A2W would work. I am still convinced that the business case would suggest moving away from any heat exchanger/intercooler. Given your (assumed experience) with turbo Buicks, why not run methanol injection? 850hp is very supportable with most commercially available systems.
Think a popular magazine is about to have folks dumping intercoolers for a "free" 44hp.

What? Why would you even consider a truck manifold in a race car?! (That was sarcasm).

For years I’ve ran 94 and meth on my GN. I’m certainly open to doing that down the road, but to start to be safe I’m planning on just running race fuel. After I see how much boost I need to run to hit my goals I could always add it.

Yes to all of the above. This is just an "inexpensive" project. The car is plumbed for E85 with PTFE lines and ethanol-ready parts throughout. We'll get it up and running on Ultra94 - add meth injection; and source a drum of E85 to keep on hand to test with for a future Drag Week campaign.
To Justa6 - dude, race gas will work fine as a baseline without the intercooler. So few folks dip their toes into that stuff any longer for a street car that its practically voodoo. Maybe just mix up some xylene and toluene for old times sake.

I'm thinking about no intercooler on this one. I was thinking of running 91 with the additive to get it upto 100 octane. Than using meth injection with boost juice. 140000 miles on this 5.3. I never tore it down to gap the rings. Just installed trick flow cam and springs. 15 to 20 lbs i'd like to boost. Some say go for it others think its a bad idea.. Still trying to decide.

I would run some type of a tank with the a2w. The more water in the system , the longer it takes to heat up. With just a heat x. Your only talking like 1.5 gallons . You would get a lot cooler temps with an ice tank . Just add ice before each run.
I am the first one to say I am surprised how well it works. When we did it I honestly didn't see it working but my boss assured me it would and he was right. It gets driven on the street regularly, he did drag week, won 2nd place in his class 1st time he did it.
IAT's are really good even with just water in the ice box.

On my 6.0 / whipple. I have a 2 gal tank with an afco heat x with fans . My temps are 25* over ambient. This is on the street . I use 70/30 water/ antifreeze . If it was a track only car , I would just have a bigger tank, no heat x. You can get IAT s really low with ice for short periods of time , but it's all u need.
