Waterford Hills Raceway Stock C4 Corvette 1st Day

- For all the Corvette fans out there! Proof that a stock engine C4 can still hang with more expensive track car options. Not bad for a first day on the track. (Obviously, the first lap is a warm up...so feel free to fast forward.)
Sorry for the camera shake. Just think how I felt driving. :) - Авто та транспорт
Thanks for driving my car on-track (Red/Black 1988 Manual Coupe), it seemed to do quite well. Long live America's sports car!
Engine got really hot cause this is a really slow, tight track

Good info. How hot was the outside air, and how high did your temps go?
It was over 90 that day and my oil got up to 296 degress. I'm pretty sure these high Temps eventually warmed my cylinder heads cause they were over .010" out of flat when I pulled them.

Well that's no fun. As I recall, the stock C4 cooling system, with the correct pressure cap rating, can handle up to 260F of water temp before the coolant boils.
Good quality oils have a flash point of around 400F, so it's doubtful the oil broke-down and failed to lubricate properly. Minimum oil temp should be above 212F so that any water (condensation from cooldown cycles) boils off every time the engine reaches full operating temperature.
As for the warped heads, unless the coolant did boil out and/or the head gaskets failed, it seems unlikely that warpage was caused by that particular episode. However, I could be mistaken, because I'm not an expert in that area.
This engine does have an iron block with aluminum heads and, since those metals expand at different rates, that combination is more likely than either all-steel or all-aluminum construction to result in warped heads as a result of overheating.
Again, good info, thanks. I want my car to handle track days with no issues, so this has been helpful. Seems I'll be needing a big aluminum radiator and a good oil cooler.
I added a permacool filter for the oil. There's a video of that alao
hands at 9 and 3! stop sliding them . c4s are absolutely awesome on the track especially for us noobs. love it keep it up!
I'll try that next weekend. I'm always repositioning, so thank you.
As a legendary driver once said (I'm paraphrasing), 'It doesn't matter where you place your hands on the steering wheel. Just do whatever feels right to you. Where you are looking and your level of concentration are far more important.'
Great car! Nice driving! #C4StillRelivant
Man you are going! Is this an LT1? I am considering getting an LT4 but the LT1 seems a lot more accessible and seems to have more than enough power. Do you have an opinion on LT1/4?
Either motor is sufficient for any 2 mile track. The issue is gearing. Even on faster tracks I never use 5 and 6th gear. Your best gain would be to use a higher ratio rear end to increase torque.
The problem with the LT1 or LT4 is heat. There is no oil cooler so you must use racing oil as it will reach 296degrees and then you must change it after a few track days. Also, the power steering fluid gets very hot, so you need to use a full synthetic PS fluid.
If you start tracking a C4, I can tell you what I've learned that helps and what doesn't seem to make any difference.
@@1eyedwillie Thanks for the info. I probably wont be doing a lot of track, im mainly getting a C4 for cruising around in the summertime and some roadtrips. But I do like to drive -efficient- so this is good to know.
When you say "stock". Everything is stock? Brake pads, brake fluid, radiator, etc. ? I was told if you really push a stock one that brakes go away after just 2-3 laps. And you usually will overheat coolant, oil, brakes and power steering fluid.
Yes, but the brake pads do start to fade during the end of a session. I'm considering C6 brakes and steel brake hoses to help.
Installed C6 stock brakes with Dynamic Friction pads and get zero brake fade during a run. They aren't popular pads but for 1/3 the price of Carbotech pads I'll live with it.
Coolant never overheats and yes, you will need Dot4 brake fluid and racing power steering fluid to handle the heat.
@@1eyedwillie what rims are you running? do they fit under stock sawblades?
I want a c4 I can take to the track and not care about damage. Don’t want to risk my c6 . You have any tips on picking out a c4??
You want a 94, 95, or 96 manual. The 96 costs more though as it has a LT4. Engines with 100k miles are still strong. You'll just need to change plugs and valve springs to bring them back to life. I have some videos I made of what else to do to get it track ready but that should get you started. Expect to pay between $8 and $11,000k for a manual at or under 100,000 miles.
Thanks
Willie is completely right about his recommendation but because I'm a simpletone when it comes to mechanics I prefer my 89 with the L98 engine, a much simpler engine, and from 88+ has all the suspension goodies from the later years
You need a GoPro 8 or 9.
I have a GoPro9. If the GoPro app actually worked, I'd use it. But yes, the phone has limitations as well.
@@1eyedwillie This was less shakier than yours hehe. : ua-cam.com/video/-nhLNBKHjUM/v-deo.html
Maybe mount in in a diffrent way? We really like car videos so otherwise than that it was fun to watch
