I am looking for a new exhaust system currently. I am looking at the Begi divorced downpipe but I dont want a 2.5" I want a 3" and im not looking to spend $400 on an exhaust if the car wont cool down.
the only thing this promotes is a cooler engine bay, air will be more likely to flow back into the crack than to extractor from. Effectively, this will increase the pressure behind the radiator. And we all know that high pressure travels to low pressure....so if you equalize the pressure on both sides of the radiator, guess where isn't going to flow through. You need to shroud your radiator. Make it impossible for any airflow entering the mouth to flow around your IC and rad. Seal the top area around the hood latch. Use good fans. Use a almost pure water mixture.
I have run tests and having the hood lifted in the rear has increased the time it takes to overheat. Radiator has cheap DIY shrouding with stock fans. The mouth of the car is completely air tight right through the rad. On the pure water mix... Doesnt coolant increase the BP of water?
The Bold was my remarks on the "see above". Brain, I am looking for a solution to my heating problems. I dont want to spend a fortune, I have a 2" rad that is dual core. all ducting is done through the front, I am going to try lowering the hood and see if that makes a difference. But the main point that I am looking for is the Solution to my overheating problems. As I said, Oil cooler is on the way, Coolant re-route is finished, 50/50 mixture of DISTILLED (yes I decided to use it this time instead of tap water) water and Dexcool, I used antifreeze because it also increases the Boiling Point of the water.
I would LOVE more suggestions and as I showed above. I AM listening to Everyones advice! And I thank all of you for it!
If a huge radiator will keep me from overheating then I am all for it, but really I just want to be able to enjoy my car at the track and not have to worry about looking at the temp gauge to see if I have started to overheat.
