what is your logic for more torque, smoother flow?

 

take a look at how your plumbing and engine bay set up is to determine what type of end tanks to use that is most efficient at distributing airflow.

i was going to do something similiar but i decided fabricating end tanks and piping was time consuming so i went with an Apexi. also, for me anyway, having a proven I/C setup that have numbers & tests to back it up is worth the extra couple of bucks. i can't afford pressure drop.

 

i have the apexi gt spec intercooler for single turbo applications and the piping isnt that long at all! maybe 12 inches on the hot side and about the same on the cold side.

 

I have no idea what a GTR intercooler looks like, but you can get lot sof cores and end tanks here...

Thanks alot that is a great link. I will be in contact with them to see what they can do for me. The end ranks are not really all that expensive either. If i do this i will take lots of pics so everyone will how to do it. I think I might be able to save a lot of money now!!

 

Alright, that was uncalled for. What makes you think you have the right to degrade a shop like that? What is your basis for the reasoning? Where are the facts to back up your claim? Have you ever been to our shop, got tech support, or even had any work done for you by us? How much water to coolant ratio do you run? Do you still have the stock ast? Do you have proper ducting to the radiator? What intercooler do you have? A properly set up car should not overheat. Water transfers heat more efficiently than coolant. Running the traditional 50/50 mix will make your car run alot hotter. Improper air ducting, such as missing the under tray will impede cooling efficinecy. Air takes the path of least resistance, so if it can go around the radiator, it will. Broken fans will make you overheat at low speeds. When is the last time you replaced your thermostat? Did you eliminate the airpump and keep the stock pullies? That would make your water pump slip. Are your radiator caps holding pressure? What coolant guage are you relying on? The stock one is a pos. I run a greddy 2 front r-spec front mount with a mazdacomp radiator, no ast, 80/20 water to coolant ratio with a bottle of water wetter. I also have some custom ducting to help bring more air under the front mount to the radiator. The space between the top of my radiator and the front of the car is sealed off by a custom shield I made to prevent the escape of air. I took these extra measures because I use my car for everything from street to drag to road racing. I also still have my a/c. On a hundred degree F day I can cruise with the a/c blasting. My coolant temps will be between 98-103C. If I am in traffic for a long time, then the temps sometimes creep up, but at that point I just turn off the a/c. Without the a/c they will drop down to the low to mid 90's. Yesterday it was about 90 out, and I drove for over an hour to the track with the a/c blowing. Coolant temps were about 91C. On a road coarse with ambients temps in the upper 80s, the hottest my car got after 20 min of flogging it was 100C. was stating my opinion, which I obtained from my own personal experiance as well as observation of others. I have owned 4 rx-7, over the past 4 years. Three of them were third gens. I do all my own work on my car now. My boss Steve has owned his third gen since new. He has tried countless setups on it. He learned to do everything on the car himself. You don't build a 10 second street car without knowing what you're doing. I see that you have a stock mount intercooler and a Koyo. The Koyo works pretty well, but not as well as a Fuidyne in my opinion. Still, it should be sufficeinet. Obviously you have a problem elsewhere in your coolant system. I'd be happy to look at your car for you, even after you badmouthed me. I can fix the problem and then you can come back on here and appoligize. I don't need to do this. I have a plentiful and loyal customer basis. I'm willing to do this because we are an honest shop that has the customers best interest in mind.

 

I must apologize to gotham racing. i have received a few posts from them stating the post was offensive. as i stated earlier the post was not personal and Im sure gotham racing does good work as many people in the Dallas area have used their services and have stated the work was excellent.

 

I've also heard that removing the cats is good for getting heat away from the engine bay. Anyone confirm/deny this?

 

Yes the precat traps a ton of heat in the engine bay. Replacing it with a downpipe helps greatly. Potatochobit, thanks for the appoligy.

 

Potatochobit: Apology accepted. Sorry it came to this. If you do need anything please feel free to give Gotham Racing a call. You'll get the same great customer service Gotham Racing gives everybody.
