Can anybody tell me if the ATR header changes the location of the ishi turbo and stock ford intercooler ?

It keeps things in the stock location. The ATR header enjoys a horrible reputation for cracking and not so great construction. Do some research here and at Turbo Ford before you buy.

I am looking to gain HP do to rules restrictions and in round robin competion the stock manifold gets so hot,I think it was something to do with the cars inablety to dial it consistantly . What do you think?

I looked at the log but the header looked better . the intercooler gets so hot i saw a post about a fan under it .

After talking to some local people in the family muffler business for over 30 years, they ditched aluminum anything for carbinized steel mostly due to the fact that, as Pete mentioned, cracking. Those who have bought atr downpipes, mufflers and headers may have had luck with theres, but the general consenses is that aluminum is not so hot anywhere on the exaust.

I'm not sure what "round robin" is in and I don't know what the rules are. If you work the engine hard, the manifold is going to get hot, no matter whether it's cast iron or stainless steel. That in it self is not the problem, It's what the heat does, primarly to the intercooler sitting right above it. Jeff's fan idea would be good if the rules allow it. A front mount could be even better.

You can wrap either the manifold or headers with availabel heat wraps and it's proven it will make more power by keeping more heat in until it passes through the turbo charger. It is also proven to degrade the wrapped parts quicker. It would help keep the intercooeler and possibly the whole engine compartment cooler and that may help consistency.

You only need two tools in life; WD-40 and Duct tape. If it doesn't move and it should use WD-40. If it moves and it shouldn't, use Duct Tape.

I think the little turbo has more to do with the heat backup.
I noticed my TC intercooler was substantially cooler after I upgraded to a .63 turbine.
But that doesn't help you if you are restricted by stock rules.

GaryS#2 has a point... the more efficient the turbo is, the less heat it will produce for the same flow (not psi, thats a whole nother matter) same thing goes for the intercooler. Just cus a intercooler flows better than another one dosen't make it more efficient.
Pete also has a point about header wrap. Most header mfgs will not honor the warrentey (bad speller) if you use wrap. However... most allow the use of coatings (i.e. jet-hot and the rest) If you run a race engine and don't mind having to replace the header every so often, wrap is the answer. It lowers the temp under the hood but also cooks the header, traps moisture, and generaly wreaks havoc on the metal.
A cooler fan will help the situation, but the answer is to move the "interheater" from it's pearch slightly above the hottest part of the engine. Almost anywhere could be better than that...
Ram air is cool when you are running down the road, but stopped in a staging line or in traffic the scoops on the hood become heat releasing snouts for the turbo and the rest of the engine.
