408 overheating in high temp with SSRA
408 overheating in high temp with SSRA So trying to look for some idea's to cool the car down... Car is getting warm going down the highway and during wot pulls. I'm thinking the cause is my super sucker ram air and the air shroud delete but I would like to be able to keep the ram air if possible. I just put a 160* t-state and I'm going to tune my fans to come on sooner when My efi live software comes in, but looking at a few other ideas to get air going through the radiator down the highway. Has anybody cut the holes out in the fron bumper support to get air coming through? Any other ideas?
Dealing with a similar situation with my 408 getting up to 220* cruising at 50mph. Front breather so its certainly not related to any ram air design. LT1 radiator with higher capacity full of 50/50, stock fans, low temp Tstat, and a/c condenser removed long ago.
At the moment I have a section of sheetmetal attached where the front bumper curves up to the radiator stay giving plenty of dead space in front of the radiator to draw clean air.
Is your air dam installed? Lately been planning to extend the stock piece to scoop more air into the radiator.

If you removed the air dam get it back on and see what it does. Had the same issue with my car when I removed the air dam for my procharger twin coolers. I ended up making my own air dam when I switched to a front mount intercooler and my cruising temps are 185-190 now.

Both the chin spoiler and the divider panel serve to
push air into the radiator and both need to be there.
I found my SLP CAI shrouded the radiator face too
much and expect the SSRA does the same (but with
less heat pickup from the radiator face through the
plastic. You might look into shimming the SSRA duct
away from the radiator (condenser) face as far as
the other stuff in the nose will allow, to relieve air
obstruction. Take any trans coolers off the condenser
face and mount "dope style".
160 'stat isn't going to help overheating any. Fans, yes.
Cleaning condenser and radiator fins, hell yes.

The fans and shroud are important for air flow at speeds less than 40-45mph or so. Once above those speeds, then the fans don't rally do anything except restrict air flow.
As said above, if you've removed or lost the air directors, that's a problem.
Highway speeds put less strain, and require less power production than driving around town. If it's getting hot there, look for an engine problem, like too incorrect timing, lean mixture, or an exhaust restriction.
