Intercooler chiller?

[Paul Bellisario]

right now i am running the dutt neck ic on my tta, wondering if that should be good enough for 11s what if i sprayed it? and how much of a difference getting a stretched sl ic or a front mount would be? hp gains? 1/4 mile gains? is it a huge difference?

What have you done so far??
Suggest you "baseline" the car, tune it to the max. See how far it will go, in it's present form. Then decide, if you want / need to go w/ that mod.

Why a 3" up pipe? You don't need to spray the charge air cooler. I agree with Mr. Leeper, you need to base line the car then push it till its inefficient. Then upgrade the cooler or possibly an alcohol kit. Or both.

have alky….

I ran 10.80@124 on a stock long block TTA with a Dutt neck IC On a TTA I think Dutt neck and alky is the way to go

Your setup should supply plenty of fuel, crank that boost up and lay down a number.
What kind of 60' are you puttin down?
Mph in the eighth and quarter?
Numbers on your powerlogger look 'right'?

Why not run a cool box, before a run load dry ice in the box and pour methanol/ethanol into it. That will certainly chill the air going in. Can also do the same for the fuel, but with EFI I am not sure how that would go.

 

[Paul Bellisario]

where do you get a chill box has anyone done that and how does that mount?

Waste of time and money

The stock intercooler is good for 11's if that's your goal...spend $ on other stuff..

 

[notacarlo]

You will be the only one on this board chilling your cooler. Better money to be spent.

Just curious, but why do you need a slower flowing airstream in the up-pipe due to alky?

 

[scojack_2001]

I went 10.97 @ 123mph with a stock GN Dutt neck IC in a full weight GN. Tune the car. Turn the boost up and add the alcohol. I ran 27psi on that pass.

 

[Paul Bellisario]

what are you talking about slower flowing airstream lol?

 

[notacarlo]

3" up pipe. The added volume slows the charge at that point then is bottlenecked into the throttle body.

I assume....as earl thinks alot more better than I does.

What if he has a bigger TB and a Kenne Bell doghouse?
Sorry for hijack but I may be on the same boat.... but have the 3 uppipe in the works and running a stocker 2.5.

 

[Paul Bellisario]

i have the 62mm tb. and the difference between the 2.5 and 3 in its so minuscule it doesn't matter.

Actually it's fairly substantial. When you start increasing tube sizes it increases at the rate of pi. A 2.5" tube has a cross section of 4.9 square inches, a 3" tube has a cross section of 7.06 sq inches. With a 14" long pipe that means you have 98.91 cubic inches to pressurize before any boost makes it to the TB/plenum area. With a stock 2.5incher, it's only 68.6 cubic inches. Damn near 2/3rds in displacement. Since it's in front of the throttlebody the additional volume doesn't count as plenum area.
Plus a 2.5" pipe that's 14" long has 109.9sq inches of lateral surface area as opposed to the larger pipes 131.88 sq inches....... Not exactly miniscule numbers and percentages.


Since we know the air will be going slower in the larger pipe, according to Bernoulli (who might have though about stuff even more than me) pressure goes down as velocity increases. So slower moving air will have more pressure in it, less tumble and other stuff going on.... And lower pressure air can fit through a throttle body easier and have less pumping losses going through the port so it can nail the intake valve.

My question was why does alky need a larger pipe? With more volume to pressurize, and slower moving, less energetic airflow, I was hoping you'd thought of something I hadn't.


Difference of opinion I guess. Personally I want my air hauling as much ass as I can get without running into scrubbing losses. Even with my alky nozzle screwed into the side of it.
