Alky forgives alot of overheating problems.... If you want to go with bigger cubes I'll give you all the results of my R&D. There is a possibility that I might develop a retro fit kit and a complete package based on my new design. Separating and insolating air, water and oil cooling processes is vital for cool operation. Last evening the abmbient air temp was 76 degrees....my coolant stayed around 162 in town..... and late in the evening it dropped to 154! Let me know if I can be of help.

 

Can guys without FI chine in ???? ...... or only

well since this is in the FI section you might want to reassess..

 

go ahead...any thing that may help...

 

Food for thought. Another problem I see with these kits is that the effective area is reduced by about 10-15% since the surface area is laid flatter than original. I also think that having the radiator laid flatter you lose air flow thru the fins. Think of it this way as an extreme example. If the radiator was laid completely flat no air would travel thru it. What would make a big improvement would be to have a custom radiator and condenser made which would be about 2" shorter and of course twice the thickness like the dewitts and ect. This would get the radiator lower for the intake pipes to clear and allow the radiator to stand more up right for improved airflow. In addition have the fins angled down so that the air would travel straight thru.
BTW: I have not had any issues with overheating with my A@A Vortec kit as of yet. I also have a smaller HP setup.

 

Well you guys might want to differentiate who has MN6/12 vs A4 with torque converters. And if you are running separate EOC or TOC. As this will contribute to over all temps......

Great idea about shorter radiator & condenser. Maybe one day we will see these components incorporated into supercharger kits. In addition to that, a smaller intercooler exposed to direct cool airflow would be more efficient at lowering IAT's.

 

Good analysis....your reasoning is why I relocated my radiator back to the more vertical position. The shroud that separates the intercooler and radiator forms a wedge shape compartment in front of the radiator. As captured air (from under the car) moves up the wedge it accelerates and hits an angled section of the shroud. This redirects the incoming pressurized air towards the radiator. This part of the design is responsible for the very low coolant temps and efficiency. Yesterday, ambient temps were around 75 degrees.... my coolant temp cruizing on the expressway was 154.... on a recent 104 degree day in Chatsworth, even hard town driving kept coolant under 189 degrees

 

How was your radiator positioned at a more vertical angle & still maintain clearances? Was it custom built or mounted differently. I have the standard angled setup.

 

Because of the large 4 inch intake pipe in the A&A kit, it required a layed down radiator for clearance. My intake pipe is only 3 inches in diameter and follows the lines of the shroud...this gives an extra inch and one half clearance to move the radiator to a more vertical position. The radiator sits a little lower than before.... I redesigned the mounting bracketry.

 

Guys -
First I actually race my C5 a lot./760 RWHP
Best 9.65 @ 140MPH, 1.36 60'
C5-R Block(No water jackets between cyl.)/F-1R @ 16.5 lbs./Also street driven/93 oct.
1. Griffen rad. w/16" single fan on a shroud.
2. 20% dex/80% distilled water w/Purple Ice.
3. Mezzure elec. water pump.(55 GPM)/ 170 stat with hole
4. No Ac core
5. Tiger Shark front end. (Air Dam shortened 1" for 1320 lights)
6. FLP Oil Cooler & Tranny Cooler.
7. ECS After Cooler & Bracket setup.
8. Remote fan switch for staging lane heat control.
9. TB Bypass.
Results: Street about 203 @ 90 deg. Amb., at the end of 1320 185 ECT/195 IAT @ 6600 RPM/141MPH.(At 85 deg. Amb.)

(PS If you want real HP you will have to deal with the HEAT!!! No way around it!!)

 

Simple solution (you might want to add it to the poll)....move to Alaska.

 

Exactly my thoughts, I searched for a "short" radiator but aside from mortgaging my house for a custom unit, couldnt find anything.

 

Went to Home Depot today and spent less than $5 on a lint brush....long skinny brush to clean lint from your dryer vent...just ask for one in the washer /dryer section....works great for reaching down between the 2 pieces....

 

Putting this on my shoping list

drove the car today....the cleaning seemed to help a bit..temps down another 10 degrees...

 

Great to hear this, how much crap were you able to clean out

 

actually I was quite surprised..I thought it was pretty clean before but this brush removed stuff that I couldn't really see...my neighbor was He can't stay away when I open the hood...he was like...WTH you doing now
