Need one for an 80 c10 . 5.3/s480. Was looking at the summit ones? Any good ?

 

The big ebay 4" is easily the best bang for the buck.

Definitely better intercooler, but in this case, paying 3x as much won't get you a 3x better intercooler.

 

i have used to mishimoto 3" in my last nova . worked good for me on my 6.0 s480 . ran 9.38 at 143 on 16 psi. 3500 lbs

 

I saw some really nasty pressure drops with the typical ebay 31x12 units. They also don't weigh near what a Treadstone does. To me that shows a lack of core density by comparison. My 31x12 4.5" treadstone was literally twice the weight as the 31x12x3 ebay unit it replaced. Cooled better with less pressure drop as well. The once a year black friday sale at Treadstone is hard to beat for price VS performance IMO.

This unit is still on sale. Tough to beat at $342 shipped.

Do you need a discount code ?

 

No, Just add it to the cart and you'll see it drop to 342.

 

Damn, the 1245 Treadstone I paid $450 for, is like $280

 

Best bang for the buck is skipping the intercooler! Often not even needed especially on the typical street strip 9 sec car.

 

LMAO as long as you're not running pump gas, this is pretty true.
It doesn't do a ton for detonation resistance on pump gas, but anything helps there.

The extra HP is the main reason to run one though. We were seeing 120+ HP gains over no intercooler on a 1200 HP setup when using an A2W on the engine dyno with the reservoir filled with methanol and dry ice.

 

That doesn't seem very practical! So what kinda gain on a normal old ice water? Less than 10% seems like an ok trade off to not have to deal with the added weight/cost/BS. I was thinking typical gains were much higher. Around 1 hp per 10 degrees.

 

Yeah, I'm not a fan of A2W personally. I'd never use one in anything other than a strictly drag car.
We didn't do it because it was practical. I wanted to see just how much power could be gained going from ~250+ IATs to ones below 0*.
A 10% gain is a lot considering the intercooler was probably undersized for what we were doing.
I wouldn't doubt another 40-60 HP on a proper intercooler/pump compared to what we were using.

 

In real life it doesn't seem to make a huge difference, 100* to 200* got to the point we didnt even pull timing till over 200* because engine didnt care.

Nice part is quick turnaround too, no swapping water, ice or waiting for a big heat sink to cool down, returns to ambient almost immediately.

 

Does that ~100whp include a timing pull or just back to back IAT change on same timing?

Was the power adder tapped out at 1200hp?

I ran E50 and no intercooler on a GTX55 94mm and twin 7875’s so basically endless boost on tap with either setup. Seems to perform on par with E85 without taxing fuel system as much and get better MPG.

 

Had some buddies run 7s with the bigger Treadstone a/a's.

 

I thought you were a fan of the A2W on the street stuff. Didnt you so logging and didn't even turn the pump on and the IAT rise was only like 10 or 20 degrees or something?

 

Indeed! Can also run 5’s without one just depends.

I’ve had good luck with treadstone units, I saw they have some “R” cores that may work better as well.

 

I’ve done about every way imaginable. It depends but I usually like A2A for street especially for cars that go out the door never to be logged or maintained again. I tried A2W with no water on street as well which worked pretty well surprisingly, just oversized the core a bit acting as a heat sink without the weight penalty of a water tank. A2W with ice water is great at the track but like you said even without ice or pump it worked well enough you hardly notice a difference in performance.

No intercooler is just fun, great response, and it confuses the majority of people. When you get sub 3000lbs the weight seems to be worth more than the meager power gains.

 

That darn magical E....so much cushion in a tune with it.

 

Its is nice especially for $2 gal. I’ve run a lot of boost with no intercooler on pump gas and meth too, just works out to be more expensive than E and doesnt smell as good.

 

LOL. True that.
It looks like I'm already spoiled from the Flex Fuel out of the pump...It's up to $2.49/gallon now around me, and I actually was a little pissed when I noticed that...especially since Top Tier "super" unleaded at Costco is $2.29/gallon.

My car actually seems to like the diluted E (60-70% from using more 93 unleaded) better than 80-85%
