Re: ATI Overheating Problem SOLVED (ganson)
Sorry it took so long. There is a pic of the unit installed at: http://www.ganson.com/dualfansinstalled.htm
The air filter is a standard Fram panel filter (in the pic it has an orange rim with a white center).

Re: ATI Overheating Problem SOLVED (ganson)
When you get a chance to autotap your setup, bring the car up to operating temp and let us know how the IAT numbers are during and idle and during/after sustained WOT runs. Also how the engine temps vary under the same conditions. Thats the true test of how the radiator fans and airbox mods work. I hope it works well, I am just curious how the new design actually works now that it is installed in your car. :)

Re: ATI Overheating Problem SOLVED (vetterdstr)
I'm not sure when I'll have the opportunity to do that, but to me the true test is idling in traffic on a hot day, as that's when I had problems with the ATI shroud.

Re: ATI Overheating Problem SOLVED (ganson)
I agree that is a problem with the ATI fan system. One of the other problems which we are discussing is the Intake Air Temps rising under WOT conditions. It pulls timing and lowers HP considerably. I was wondering if your new air box design actually helped that out or not. Post some traces when you get a chance.

Re: ATI Overheating Problem SOLVED (vetterdstr)
Will do. I would guess though, that it would be better to pull air from the outside, rather than from the engine compartment as (I think) all of us do with our various setups. Although at speed, I wonder how the air flows through the engine area; maybe it flows enough that the intake air temp isn't that much higher than outside?

Re: ATI Overheating Problem SOLVED (ganson)
The air on the backside of the radiator is much hotter than the front of the radiator. In addition to the S/C, small plumbing with many 90 deg. turns that create more friction (which creates heat) in an O2 molecule, in addition to the twin intercoolers not cooling enough, all contributes to heating the air before it gets to the IAT sensor and your engine.
Put it all together and it spells LOSS OF HP for the LS1 engine. Tuners can overcome inherit problems by adding fuel in the lower RPM's which will actually help the engine run cool... but take your car out for hard run for 5 min or more with all those things stacked against the engine and IMO... the engine wont perform well. This is why you have to think out things very carefully when modifying your car beyond one companys attempt at a total package. :yesnod:

Re: ATI Overheating Problem SOLVED (vetterdstr)
I guess I could tell you all the problems that can be encountered with the system and what you can use to fix them. If you have not taken the system from one end to another you will never know how much difference changing all of those things can make in the final product.
At this point, if you are very happy with what you have then that is all that counts. :) No need to get back to me with those traces, I could pretty much guess what the outcome would be at this time.
Best of luck to you all with your Mod decisions. :blueangel:

Re: ATI Overheating Problem SOLVED (vetterdstr)
I do know how much difference my mod makes: It runs 30 degrees cooler than it did with the ATI shroud.

Thats great! At what point are you going to find out about the rest of the problems and fix them too? Or is it ok like it is?

vetterdstr: What other problems are you talking about? My car runs great, is reliable and doesn't get hot.

Those are the problems, You wont know these problems exist if you dont run traces on your car.

Re: ATI Overheating Problem SOLVED (vetterdstr)
My shroud draws air from the same place as the ATI shroud does. I designed it to solve the overheating problem, and it does exactly what I designed it to do. If anything, it improves performance because the engine runs a lot cooler.

Re: ATI Overheating Problem SOLVED (ganson)
Ok, so you have solved temp problem... what about the rest of the problems? Are you aware they exist? If not it is ok... just wanting to know what you are going to do about them or if the system is to your satisfaction at this time.

Re: ATI Overheating Problem SOLVED (vetterdstr)
Well I think that Vetterdstr has brought forth some issues that even I didn`t think about. I know that doing certain things to a vehicle will cause other things to get better or worse. And yes ganson your car I`m sure runs cooler now, but I think you should have it all checked out to get the most out of what you have done. Vehicles love it when everything is working together and that will be some satisfaction to you to know that your car is the best it can be for what you have done to it. Your idea as I said earlier seems to be very good, but don`t just be concern only about how cool it runs. Well, that is what I had to say, good luck .

Re: ATI Overheating Problem SOLVED (Am I Badd)
Well, my car does run quite well. The new shroud didn't change anything except for how hot the engine runs. As I said, the ATI shroud draws air from the same place, so I don't see how the new shroud would have any negative effect. As for the other "problems", I've heard about the single intercooler, but I have yet to see any hard numbers relating to it's effectivness. If you know of other solutions, please share.

Re: ATI Overheating Problem SOLVED (ganson)
Ganson, I have to agree with you on the location of the ATI shroud being located on the same side of the Rad as yours which should cause the same affect on the temp. of the air intake. But I think Vetterdstr was saying that both yours and the ATI system would be better as far as performance is concern was on the other side. It`s true that the cooler air makes more power. But also I think you are more concern about your cooling issue . Which is also very important. Your post was about cooling not about cooling and best performance. I also see your point as well.

Re: ATI Overheating Problem SOLVED (Am I Badd)
Yes, the engine coolant temp was the problem addressed (and solved) by the new shroud. That was my priority as it gets to 125 degrees here in the summer, and the ATI shroud, oversized fan or not, doesn't get the job done. As for air temps at the intake, I'll watch and see what solutions arise and how much they help. If you know of any, please let me know. I'm always intrested in improving what I have.
Thanks
