Difference between intercoolers

[grass doctor]

Like pronto said dutneck ic..
Combine it with Razor alky/93 , 42lb injectors, 49/44 turbo garrett or BB restalled d5 or tight 10.5" properly tuned & your killing kool guy cars while getting close to 30 mpg with your foot out of it on the highway.. My theory is everyone loved these cars way back when so why stray TOO far from buicks original design?

I put a dutt neck stocker on my car and got 2-3 more psi...

My current hybrid project is running "hot air" with twin meth nozzles. Build here --> 1st gen F body
It runs amazing, around 150 inlet temps cruising around and drops considerably when you get into boost. Unfortunately, I can't stay into it long enough to see what the temps settle at, due to wheel spin and sideways at anything over 1/2 throttle, after 3 seconds its below 100 and still dropping.

Eventually, I hope to tame it down with a rear gear change (currently 4.11) and more boost control tuning.

 

[Mr.Spool]

Us boat guys have a great advantage, the entire lake to cool our charge coolers! When its 115 degrees in Havasu or Phx, its possible to get below ambient, since the lake is about 90 degrees, and much cooler up nearer the dam. I usually run 11-12 lbs boost, that nets me over 1100 hp. without the squeeze (14-71 high helix). The foggers (16) drop the inlet temps even more, like a rock!

That's a bad bitch

Nice, pre and post turbo alky injection.

 

[TIMINATOR]

Hey Spool, do the nahara guys allow water/air intercoolers? Ennybody run them? Street or track?
NHRA use water injection, or water alky?
Seems that alky is a fuel, and they must run gas. Or is it different for turbo cars.

I have a friend with an LS swapped T that runs low 8s. He at one point made his own water intercooler. Ended up ditching it. Weighed too much and results weren't up to snuff. He also sprays a ton of alky. He usually runs in no time races.

Plenty of guys run them up here.
Actually the water intercoolers go right where the manifold is and takes a ton of weight off the front end vs the air to air.
I've seen the air intake charge data and they work very well.
But you need to be able to go up in height and the car needs a serious cowl

 

[TIMINATOR]

Geez, as hot as it is here, I thought I would have seen some out here. I have seen just one!
Mebbie its because we dont have a local track anymore, and on the street its prolly not worth the hassle.
Then again, the more alky spray, the cooler the charge is anyway.
Back to the"does the NHRA allow alky injection" question....

I don't think in specific classes. It's allowed on street nights and non NHRA events like No Time at NED.

Water injection is a pass bypass thing.
Inmo not a prolonged hit by hit thing.
Alky injection has a reservoir and can make some repeated hits before needing attention.
Water injection not so.
NHRA stuff is a class by class situation.

 

[Mr.Spool]

Water injection has been better than air to air as long as the ice gets replaced lol.
Alky injection as good as the tank is full
I still have 4 nozzles on my e85 nt street car

I run a liquid intercooler in one of my cars with antifreeze and water-wetter mix and it is tapped with a temp sensor its never more then 8 degrees above ambient cruising around, under boost temp rises quick but recovers just as quick in a few seconds..i have an ice box that i never put in but ive seen a frosty up-pipe on a friends tta 20 years ago pretty cool stuff.

Cool! So to speak....
Water tank in the trunk?
I remember in the 60s, the Mallicote brothers were running an, I think, Factory eXperimental car (prelude to funny cars)
with a twin turbo, stack injected hemi.
Concerned about inlet temps, they made an intercooler box for each that sat on the inside fenders. A bolt on top, and a rubber gasket kept the box sealed. And UNTIL the boost was raised, it worked perfectly, but it didnt have a vent. When they really got the boost up, it boiled the water! Then predictably it exploded the boxes!
A big vent and hose, and filling the box with ice cubes and water was next, then they put chunks of "dry ice" in there too!
They were ahead of their time, but I don't remember what happened to them.
Probably NHRA rule changes.
My favorite "innovation" class was Blown Alcohol dragster. You could, at different weight and cubic inch limitations run:
Single blown alky engine
Single injected nitro engine
Twin blown gas engines or,
Single turbo charged alcohol engine
I watched Chess Bushy set everyone on their ass with his injected nitro engine, about .4 sec, and 8 mph over the field at the winter nats.
Then the turbo guys got their stuff together and the NHRA went back to blown alky only.
They destroyed the only truly innovative class!
Why?
No noise, no flames out of the exhaust, and not a lot of breakage,
They went back to Cookie cutter cars, like every other class, Indy, and NASCAR. Same stuff, different paint jobs. A lot of us put our race engines in boats about then. No speed limits on our lakes, and they are big!
We had our own "run what u brung" Friday nite drags at lake Plesant for years!
Lake Havasu has a TON of stupid fast boats. Google it. 600+ inch blown, inter cooled, twin and triple engined, and the occasional turbine Huey Helicopter powered stuff!
I'll start with alky injection, and go from there.
Trunk and interior temps can run 130 degrees here in the summer. Hot intercooler water, bad. Mebbie I can duct the cabin outlet air into a duct in the trunk to cool the intercooler tank!

Cool story, Yes a small aluminum box like a mini fuel cell that mounts in the trunk with lines and a pump, ice will melt quick so you would have to load every run if you didnt hot lap then you would get maybe 2 runs in.

We also had to drain the hot water out

Pre turbo and TB meth injection?

Yes a nice harbor freight $4.99 hand pump

Yea every pass though
A lot of work lol
I prefer the alky injection

No doubt, thats why i never hooked it up. the liquid i/c car never see's the track anymore

 

[TIMINATOR]

Ideas, ideas, ideas......
I gotta get mine together and see what I have first, then!!!!!!
But if meth cools the charge that much, I prolly wont need anything more, but I'll still.......
