GT350 vs. Z/28

Chevy sold a dud just to get headlines. Motortrend should be ashamed of themselves.

So, larger grill area the problem should be solved right? Wrong... As we have heard from the GT350 drivers on occasion, the GT350 requires good air. Air that is only available if the car is in first and in no traffic. I clearly warned the GT350 would more than likely need to drop the mesh like the Boss did.

Are you thinking that temps will still be an issue with the GT350TP and GT350R?

I am also concerned (not due to knowledge of Ford's history specifically, just due to having a high HP engine). I reviewed the long version of the Winding Road GT350 ride along, and found that there was a noticable oil temperature rise. Don't know the temps in Grattan on the day of the actual drive, so not sure how close to the limit things are.

Here is the video:


Attached photos show:
1. A reference photo to get an idea of how the temps relate to gauge position
2. A screenshot from the beginning of the ridealong
3. A screenshot from the end of the ridealong

To me, it looks like the temps started a little under 250, and ended somewhere under 300, maybe 275 or so.

Oil pressure looks to be a little under 100 (maybe 90 or so).

Anyhow, not sure if this means anything at all, but just thought it would a fun topic about which to freak-out.

I don't think there will be a problem with temps near 300. This article eased my mind on oil temps concern.

For a dual-purpose car, engine oil needs to be at least 220 degrees F to burn off all the deposits and accumulated water vapor. For every pound of fuel burned in an engine, the combustion process also generates a pound of water! If engine sump temperatures rarely exceed 212 degrees (water’s boiling point), the water will mix with sulfur (another combustion by-product) and create acids that can eventually damage bearings.

As for ultimate power potential, the general consensus among most racers is that hot oil and cool water make more power in most engines. Cold engine oil causes excessive frictional drag on the bearings and cylinder walls. A quality conventional motor oil will tolerate oil sump temperatures of up to 250 degrees, but starts breaking down over 275 degrees. The traditional approach is to try to hold oil temperatures between 230 and 260 degrees. Even on a short-duration, drag-only combo where oil is frequently changed, I would not want to routinely see under-200-degree oil temps.

A full-synthetic oil will withstand sump temperatures in excess of 300 degrees, and for hard-core professional racing, some oval-track race teams are experimenting with ultra-thin, specially formulated, race-only synthetics operating at 350 degrees or even higher.

Also remember that a high-end engine is built as a total combination. Piston-to-wall clearances, piston ring end-gaps, and bearing clearances are specifically tailored to match the engine oil’s characteristics and intended operating temperature.

Anyone have the issue of clicking on page 84 and it goes back to page 81, which means that there are only 81 pages...

I believe its because of deleted post by mods or people themselves, it messes up with the page count.

Yes, performance vehicles, especially at this level, will have extremely hot oil. How long it takes to get that way is another story. The Boss ran hot, GT's ran hot... the GT350 isn't immune to heat stress, just as long as it's not burning the oil the first few laps.

I'm pretty sure you will need to drop the mesh too. In fact, I wouldn't even try it in some states. 275-ish is still too warm for oil, I'd feel better a tad lower...

It's possible once that mesh comes down that more air will be available to the oil cooler. Though not much... Excessive hoodlift will occur more than likely.

Bet my '79 Stang is faster than your car!:ford: I've been 8.99 in the quarter......How about you?

I appreciate that you're on here with input from the Camaro side and track experience. The 1LE and the z28 are the cars I would get over my 5.0. Especially after they did the refresh in 2014.

Btw, are you going to get a GT350?

2016 1SS starts at $37,295.

MRC? $2600
Dual Mode? $1500
Black Track Wheels? $500

About $41,995 for the above...


Future brake upgrade? $2000
Future wheel upgrade? $1500
Future Recaro option? $1500

About $47,000-$48,000 for a future 1LE option with ZERO weight loss figured in.

Nah......

It's officially begun... :cheers:

Time for some performance specs.

I don't think Ford will say anything.

I hear Ford is leaving the performance figures up to the customers, media and race teams/drivers.


I don't really value manufacturers times anymore. I want to see real world results anyway.


What IS better vs. what's marketed better...

#15 GT350R totaled again, withdrawn for the season...

#158 finished 3rd, Rum Bum 4th and Stevensons #6 was 7th...

Rum Bum will likely push the z28 out of #1

Edit: Qualifying only, I seriously don't follow this nonsense.

GT350s sure are good at taking themselves out of races lmao. The last ten minutes of this race was absolutely insane what a crazy turn of events with cars running out of gas on the last lap.
