A2A observation

[TYTILIDIE]

Ive been tuning the last couple days to get ready for the track and one of the first things I noticed was that my IATs were at 120* at idle and cruise it wold go down to 110* almost instantly. When Ild go WOT, it would drop waaay down to the 80's and 90's, this is on a 80* day but the IATs would start fluctuating really bad.They would go from 85ish down to -5 so I replaced the MAT sensor and now all is well. I am very impressed to see the temps go down, even under boost. So far I have yet to hit over 103* on a WOT run, and thats in the heat. I notice a lot of people ask for results when switching to A2A and noone ever posts them up so I thought Ild share

Re: A2A observation

Are you sprayin alky or meth?

When I had A/W you could watch IATS drop as the alky sprayed down the track.

No datalogs for the A/A with meth yet, but I am expecting similar results.

I know mike doesn't have an alky kit yet. We were just talking about that yesterday to help out since he is only getting crappy 91 in his area.

Hell yeah. What about the actual performance (seat of the pants, datamaster dyno, dragstrip ET, etc.)? Can you run more boost with the same fuel octane?

We only need 91 in our area. High altitude = less air = less need for knock retard. Just FYI :tup:

I dont run alky. Seat of the pants, lets just say you can feel it, Im not saying its a huuge deal but you can feel it. When I had W2A, Ild watch my temps sky rocket to hte 140-160* range depending on the outside temp. This is on a full 1/4 run ofcourse and I had a Shurflo, hotwired all that good stuff. A2A is the only way to go IMO.

Re: A2A observation

The problem with A2W is the heat-soak... you already knew that, of course, but you can help with that on an A2W by having a big radiator for your intercooler. My boss uses another AC condensor coil, and it works great. Also, you can use an extra resevoir. Technically, an A2W has more potential to be more efficient across the board, due to your not having to be moving to be cooling.

Ive argued that many times with guys in town and I always come down to the fact that while this may be true, its one less damn part to fail, i.e., the pump. Its one less thing to leak, well...sort of, leak a fluid anyway. There are ups and downs to both for sure but for the looks you get out of A2A and the less headache, after install, I could never recommend anyone to go A2W ever again. Ild almost say its only real benefit would be if it was in a real cramped space, other than that, whats the real point of cooling while you sit, especially when the A2A will drop temps fast enough to do what you need done?

Bias disclosure: There's probably nobody more fond of the stock A2W SyTy intercooler than me.

I don't know why you guys always talk about the IC pump failing. I still have my original one with 78,000 miles and it's been hotwired since 25,000 miles in 2001. Works flawlessly. As for the "heat soaking" of the stock unit, I road raced with my stock A2W and it worked pretty decently. The temps did not skyrocket out of control. I think a lot of people assume that if one thing is stock, and another thing is aftermarket, the aftermarket thing "automatically" provides better performance. In my experiences, that is often not the case. :2cents:

There is no doubt however, that the A2A makes the truck a lot easier to work on.

Yeah, at the end of the day, thats my real argument. I had my Shurflo since 03 and it worked til the day I gave to Austin. Still, just ugly IMO :lol:
