Re: Track Time

90 deg and a 35 mph wind at MAM Friday wasn't perfect either--but sure beats a day at the office. ;D
But if your cooling stays under control, was it the hood? Oil cooler? One of your other Winter Mods?
Hope you can lay down some good times with that new suspension next weekend.

So do I.

Re: Track Time

Yeah, he was the second GT on the video, Car #25. Only him and I had any real track experience prior to this, it showed.

I guess becasue some folks don't push "10/10ths" they don't have any "real" experience?

Boss Track Attack Day 2

None of the videos from day one turned out, had the aperture set wrong.

LOL, I wasn't referring to you--only the guys that were actually on-track with us at the same time! You were always in the "other" run group. Besides the three of us, there was only one other guy that even said he'd ever done a track day before!

Looks like you had a fun time on day 2 and managed to bring the 500S home in one piece! Great meeting you in-person, BTW!

The biggest cooling benefit will be the oil cooler. We shall see but I'm prepared to pull my grille if necessary. If necessary, that is likely still the most effective cooling mod. I have been running cooler so far this year, but it hasn't been 90+ yet.

Re: Track Time

How does no grill compare to a 302S grill, if you have tried both?

ECTs were 15-20 degrees cooler with no grille versus the 302S grille. I really like the looks of the 302S grille best, but if I can't keep it cool I'll have to swap to the Cobrajet or a billet grille. I'm sure we'll know by this weekend ???

I am really surprised there is that much of a difference between no grill and the 302S grille. Are u using water wetter? Must be because your car is too low to the ground now ! ;D

Re: Track Time

Yep using Water Wetter although I'm not convinced it's not snake oil. There's just something about the grille design on the Boss that restricts airflow to the radiator because the difference from removing it or going to a billet or Cobrajet grille is significant. They are now projecting record highs for Saturday. Since my car is basically setup just like the race car with the grille, radiator, hood and air-to-oil cooler, it will be interesting to see what happens.

Elevation is a huge factor though, even just being at 1900 ft vs sea level.

Re: Track Time

I think you hit on it Gary, the elevation is probably key here. As for the water wetter, you may be right. I didn't do an A/B comparison and since I've yet to see any heat issues at all I have no basis for comparison anyway. As we move into the summer months I am going to track coolant and head temps. At Limerock last week (track temp was 92 degrees) I actually did my last run inadvertantly with the A/C on, I noticed it just as the checkered was thrown. Per the Aeroforce the temps didn't budge at all and I was running 1:04's 1:06's which is fairly quick. Not sure if water wetter had anyting to do with that or not.

There is one solution for your problem though - slow down ! (NOT !) ;D LOL

Re: Track Time

I can attest to the water wetter doing some good. My 96 cobra I had an auto meter gauge and after I super charged it the coolant temps would soar to 215 when driving around in traffic in mayport, fl. after I put some in it dropped to 200 and would only go over that to 205 after a hard charge through the gears. Coolant temps got even better when I added a Fluidyne Rad and meziere electric water pump. Dropped to 190 and stayed there.

Also had lots of buddies that use water wetter on there 4 stroke dirt bikes and they all say it works great for them.

Good to know, thanks. For the price it's cheap insurance.

Re: Track Time

Drew has been using a billet style grille and he's not had a problem running his car in 100+ degree temps. That convinced me to get a billet style grille from the get go. Maybe there's no difference between a 302S and billet style grille but I placed my bet that there is. He just bought a 302S grille so we'll find out soon enough if there is a difference.

It may be cheap insurance if you're using it with the factory anti-freeze. For best results, you're supposed to run just Water Wetter and distilled water if you just look at their own testing. The cooling gain from running with anti-freeze is nominal. For me, I prefer the insurance of corrosion protection of the factory coolant versus trusting Water Wetter alone to provide it. Many argue you shouldn't run A/F in a track car, but again it's a measure of what kind of insurance you're protecting against. For those of us up in the North, we have to have at least some anti-freeze in until May and back in by October to be safe.

I have a feelilng there was more to the redesign of the 2013 grille than just looks. It's basically a GT honeycomb design with more opening and removable fogs. I haven't heard of GTs having overheating issues on the track

Re: Track Time

I ran a couple of sessions last weekend at High Plains Raceway... I say a couple because I was instructing and really didn't have many opportunities to get out on track. 302S grill, Tiger Hood and FRPP radiator and I still tripped the light (245* per my guage). Pulled the 302S grill for the next session and didn't even come close.

It's obviously all airflow in, not out, causing the issue.

Question for the engineers on the board. Take a look at a stock GT grill or a GT500 grill. Same surface area, but the grill 'mesh' is much thinner than the thick bars of the Boss grill. Could it be something as simple as turbulence at the bars (due to their thickness) not allowing the air in?

Anyway, I put in my chicken-wire-abomination for tomorrows NASA event at HPR. I'm going to take my dremel to the 302S grill and remove bars and replace with wire with hopes of maintaining the look and increasing the airflow.

Re: Track Time

Here's a photo of the CJ grille so you can see how unrestricted it is. You could cut out more of the vertical supports if you wanted to.

Post up pics and results after, I was thinking about doing it but have not had heat issues yet.

You guys running in really hot, high altitudes might want to look into a mister system like people use on intercoolers. It is like snake oil that actually works ;D

Re: Track Time

It's hard for me to believe that surafce area with the 302S grille is the issue. Granted the more 'open space' you have for air to flow the better the efficiency of the radiator, but it seems that the real world difference in engine temps are too high to just thin it's based on the amount of open space available for air to flow. I suspect that whomever mentioned turbulence is really on to something. My guess is these a high pressure build up in front of the bars on the 302S that restrict airflow. Just the fact that it's changed in '13 makes you believe they realized their mistake. I may take a dremel tool to my 302S grille and replace the major portion of it with honeycomb....

Re: Track Time

We don't know if the 2013's run hot or not. Anyone tracked one yet in hot conditions or high altitudes? I think it's more related to turbulence from the fog light openings.
