heat management, CF hood alternative

[GsxrMe]

I really like the hood vents. As long as they are half the price of a vented hood I think people will purchase these.

Some of us aren't scared to cut a giant hole in our hood but must are; so the price needs to be fair and right.

I'm curious as to whether or not hood ventilation may reduce or eliminate the frequency of coil pack failures. Most of the cars that see regular track duty are replacing coil packs every few months, I have a vented hood and I've only had one failure despite many track days in the southeast. Your experience?

When I left the under body pan off, after a long drive I would pop the hood and it was warm but with the pan on when I popped the hood it was like "yikes!" Hot when I opened the hood. I don't have hood vents and I really don't want to leave the pan off. I'm leaning towards hood vents.

I still may modify the pan to have 1/2 inch strips for air; Even if I get dirt or dust. These temps can't be good for long term.

Look were all beta testers for the real sti brz!

According to a post on their Instagram: "$200ish for the vent kit, over $200 with the rain guards."

We did some testing from OEM hood to vented hood with thermocouples placed specifically at both driver's side and passenger side coils (the air around them, not the coil themselves). We saw a significant reduction in temperature by going vented, so much so we repeated the test multiple times. Again, waiting to compile and sort all the information we have before starting a respective thread.

I'd be willing to bet other vents, as long as they evacuate engine bay air, will do something similar .

Another possible option?

Yes but I think it would hit my turbo/piping/intake manifold

For those curious about the Velox Motorsports kit, we have started an informative thread regarding the units. It is located here.

Would like to see a comparison of the Velox and Trackspec vents.

i did this with probes on the coils and on a track session. the header side was 25f hotter on the coils.

Something not touched on yet in this thread is that the Trackspec vents look to possibly be reinforcing crumple zones/points under the hood. These are points where the hood is intended to fold in case of a front end collision (instead of say shooting straight through the windshield.) The Velox vents do not. I'm not saying that the Trackspec mfg has not tested this for safety, it's just something that comes to mind when I see hood vents cross this engineered structure under the hood and something that should be part of any comparison.

Appreciate your thoughts, but since I’m quoted, want to clarify that I’m interested in a comparison of heat control since that is the main topic of this thread.

I think the same crash/crumple issue can be applied to the CF hoods as well.

PS - I chose the Velox and pleased.

Would removing the plastic inner fender liners help?
