ITS Mustang Results - some useful/useless information ...

[Ron Earp]

]I do not think that it is common & I tend to agree w/your sources. However, keep in mind that this engine was never designed for competition usage. The T-Bird Super Coupe was as close as it ever got to high performance.

For production cars, but Ford used the engines in the 90s for the V6 Cup series. Technically Ford used an SVO block for this that was beefed up, but more than a few folks have built clones of the engines using the standard 3.8L block and boring/stroking these to 4.5L. All the SVO parts work on a 3.8L block.



If you use the SVO block (M-6010-E380) you can get 312 inches out of them. All the SVO V6 parts were produced from like 89 to 91, so they are thin on the ground these days, but the engine has some faithful followers that use them for racing.

Information about the parts and engines is hard to get, but Super Ford did a complete tear down of the motors with a lot of technical details back in 1989. PDFs of the article were available on the web a few years ago but since have been taken down. I've got copies somewhere if you're interested.

Of course , less than 54% front weight.
Measure the pan to pickup value. Try for a little less than 1/2in. 10-12mm is good. Get rid of the inverted tapered pickup ,make a straight round sided pick up guide, around the actual tube.
Weld in small guide plates surrounding the pickup so that the oil is diverted towards the PU.
Use the dam accusump and be done with it.

When do Mustangs race at night?? The only night races are Chumpcar and the Mustangs have not needed lights yet..
Not Really , A Mustang won a Texas race.
125 cars @ Daytona, 5/27

I've got a convex Longacre mirror in my car, and I'm not hugely thrilled with it. In our Lemons Miata, we're using just a clip-on mirror cover that's curved laterally, not convex. it doesn't change the focusing and depth perception near as much as what my Longacre does. It's also closer to my head and I have a pretty wide field of vision in it because of it. I prefer that mirror over the Longacre one in my car (which was 4x the price!)

In either car/mirror though, I can see everything from my helmet to about halfway out the right door. Thus I have no need for a right side mirror. On the left side, I use a small "F1 type" curved mirror: https://www.pegasusautoracing.com/pr...p?Product=5121


Keep in mind that you don't really need to be able to focus on a car coming up behind you. I glance at the mirrors and see if there's a fuzzy dot in it. If so, I have tons of room. If there's a bigger blob, I pay more attention. If I'm on a straight and can see the blob getting bigger, then I know I'd better be ready for a pass by a faster car.

That said, your run group includes GT1-3, so you have some fast cars running with you. it's a bit different than running STU where you're more equally matched in power and there's not at much closing speed. I have a lot more time to react to oncoming traffic at the end of a straight when they're passing me at 5-10mph differential vs. 50+mph!!

Will you be at TWS this weekend? would be happy to let you take a look at the mirrors I have set up in my car.. I think I have extra mounting brackets and possibly a leftover longacre that I cracked a corner on first installation. Let me know by tonight and I'll toss them in the trailer.

You guys might want to look at some baffles in the pan, windage trays, and a crank scraper. While the latter suggestion isn't necessarily involved in oil control for scavenging it can help with power and "while you're in there" you might as well do it up right.

I think that by fully utilizing the adjustments on the HANR device, the mirror issue is not nearly as severe as it was in the beginning. And, as someone here told me ... it's just a matter of getting used to it.

The basic V6 OE aluminum oil pan is a deep sump unit & is actually better than the OE pan on the V8. However, w/that said, my problem was either the pump &/or filter. I made the 'mistake' of replacing both ... & the problem was a 'no-show' at the next race. I say 'mistake' as I should have initially replaced the filter ONLY, then, if necessary, follow it up w/a pump replacement. At some point down the line, I may reinstall the original pump which could isolate the Motorcraft filter as the problem. Anyway, as stated above, the oil pressure was perfect w/zero drop at any point on the track at my 2nd race.

That is as it should be. Ours has also been stable with the stock pan and I went back to pull some data from the oil pressure sensor that we log into the Traqmate. It is rock steady except for shifts where it drops down a bit, sometimes 10 psi if the shift is slow, but it typically hovers around 52psi when good and hot from 1200 RPM to 5100 RPM. Here is a plot, the third trace is oil pressure vs distance for one lap of RRR, our last race we entered.



The oil pressure drops during the shifts, the gear position is shown in the fourth trace. There is a little bit of a drop around 2300 ft that is due to g loading I suspect but I'm not too worried about it, at least not yet.

Ron--Ford motors are tough!

I would not worry about it.

Looks like the Mustang made it to RA and the ARRC. Nice color. How did the car run?

It felt like a (NA$CAR) Cup Car on an autocross course. The last two (2) times I drove RA was at night & on the old course. I was good thru 1 & from 5 thru 10A/B, but just never felt comfortable thru 12 (which I use to absolutely love ... even at night) & 2 to 5. I think that it was not knowing just how far off course a 3,000 lb vehicle would go that kept me cautious (& slow). That has been the biggest learning curve (for me, anyway) in that all my previous IT & Endurance cars were sub 2,500 lb vehicles that I felt very comfortable (& confident) in. As for the basic color theme & car # ... they have a historic basis in the Terlingua Racing '67 Trans-Am Mustang. Sorry that you were not able to make it. I was afraid that Sandy had something to do w/you not being at RA. As for this delayed response, I just returned from my RA / Palm Beach / Sebring trip on Wednesday. I am probably one of the last remaining folks who do not text, tweet or twitter ... or travel w/a laptop. As my kids are fond of saying ... "Dad, yer nothin' but roadkill on the information highway!"

Interesting. As I have never taken an interest in the Ford I6/V6 until this IT project, that engine never crossed my radar. I went back thru my old Ford Performance catalogs & TAH DA!!! ... there it was. Thank you for the info. Those heads should help improve my F/R weight issue also.
