They are picking up the base extremely fast.
Ben G has 2 set of stickers. And was pacing 2. 02 in a RACE! with 90f.
Gonna be a battle. But I'm gonna send it.
You keep fingers crossed for me please

Update.
Well. I'm officially behind with this write up.
I guess..life.
Let's get through some of the topics. I'm sure I will forget something but bare with me.
I will divide the post in TOPICS

ENGINE
the strong collaboration with OZTUNING continues. Im so lucky and grateful Ken Osborne decided to help an italian guy. I appreciate you.
I JUST Installed INTAKE CAMS. L&M.
Went from 480whp to 496whp. And better usable curve.
This was done also with a resonator(hpipe) in the way so we expect might be even higher.
But the results on track speak. The car is 3mph faster on the straight of sonoma and Laguna. Car has also 350mani JLT and e85

SUSPENSIONS
lots of changes here. During my service we found the front JRi were completely broken.
so together with cortex we decided to move to a Penske double adjustment.
The rear however are still JRi
Took me 2 or 3 events to get a better feeling on them. I feel we are going in the right direction but the rear still tends to snap on me during hard braking. Getting there. But not there yet.

TRANSMISSION
I could write a book on my 10speed.
temperatures are under control with the SPEEDITALIA THERMOSTAT BYPASS and my bigger cooler but the transmission keeps going down. The issue is : I'm reaching forces (lateral G) and speeds I think beyond this transmission. I can touch multiple times 2 G. THE TRANSMISSION FLUID STARVED. And I think this contributed to create the latest slipping issue.
If I slow down 2 second this transmission can last an entire endurance race.
I will install a new one in these days including extra clutches ( a mod from SUNCOAST perf) and the bypass.
Also an oem shape filter. (I also run after market alluminium pan)
We will see. Cause ai would need to send it at NATIONALS FOR NASA in sept. (No chance to test it before)

CHASSIS and INTERIOR
Well I wanted to fit 335mm tires all around and I got an ANDERSON COMPOSITE FENDER KIT to fit them. Thanks TERRY FAIR FOR THE HELP!

I installed the MMR 10speed kit for after market steering wheel. Now the car feels more... racecar! Thank you so much guys for the opportunity to be your tester.

And we'll not chassis but... I wrapped the car still not finished yet. But getting there


TIRES AND WHEELS
I went with a 335 mm A7 choice.
On a 18x12 APEX RIM. to fit under the huge fenders I needed huge spacers. 48mm front and 40mm back.

AERO
still running my speeditalia front splitter with the fast release system
I'm using still AJ HARTMAN FRONT TUNNELS/ CANARDS/ SIDE PLATES
In the rear I'm still using AJ HARTMAN FULCRUM 14 and his diffuser (connected with a fast release System (5sec installation)


What's next
well prepping for nationals (UTAH MOTORSPORT 5-8 SEPT 2024)
FINGERS CROSSED FOR ME. PLEASE.

Need to change front hubs (for longer studs)
And a failing rear left hub.

Will install SPC camber arms.

Need a new allignment and corner balance.

And last. I did some flat floor templates. Is a long process without a bridge at home so bare with me.

I think this covers everything.

Oh this year.
I ran willow
Springs (1.21)
sonoma sub 40 (at 39.1)
And Laguna at 1:30.6. I drove like shiznit. And conservative (broken trans and zero aggressive to corners to preserve the system)

After Utah I want to go back to thill and buttonwillow.

Keep you posted family!

So the car as it sits now is making 510RWHP SAE rated with the cams through an auto and you have:

L&M intake cams
JLT
Ported gt350 intake
Light weight driveshaft (maybe a couple hp)
Long tube headers
Some form of 3” cat back and resonator delete
E85 tune

Seems like with a manual this would be around 530-540Hp Std on a dynojet which is pretty incredible.

I need to buy a mach 1

The catback is what gives the HP not the headers by the way.
12 15 whp.
When we added headers was just torque.
Not peak hp.
The tuner is the key. Oztuning is the best for us road racers.
Strongly strongly suggest. Many of us use them!

Is Oztuning a remote tuner or do you work with him onsite? I'm looking for a good tuner and it sure seems like there's a shortage of them! I couldn't seem to find an answer on Google. Thanks Ale!

He is remote.
Ken Osborne is the guy.
Mustang guy. Racer like us. Wonderful person. And great tuner. Steve Esposito is with him too. And 2 other guys here locally.
Contact him and tell him I sent you. Won't change anything but was cool to say it haha

I always found this curious in your case. We found that the headers always gives us a consistent power gain of around 25hp in all the coyotes. The shop I use must have done about 20 cars. Most of them gen 3's with 3" custom exhaust, CAI, headers and E85 (no cats), puts the Gen3 cars consistently at between 495 and 505 rwhp.

I think is basically the same concept. With headers you expand gasses right away more than oem. With cat back you do that 3 ft after.
So this was the dyno. Keep in mind this was full OEM. And unfortunately done in 5th gear.(9whp) We did a conversion for 7th gear and was 12-14
I don't remember how cause it was in 2019 lol

MY theory is once u increase tube size the effect is the same of the headers.
In other words whatever u increase first will
Give u the hp peak gain.

 

[Mad Hatter]

I feel that its a little more complicated then just size of the exhaust pipe. Here is a video we made with some X pipes. The top one is a custom one my guys made up, the middle is a Borla X pipe and the bottom one is a Kooks X pipe. You can see the suction gained with a properly made X pipe, and we did the same with the merge collector on the headers as well.

What was a pretty big shock to me was that the Kooks X pipes had no extraction at all. As for headers, our Ebay US$250 coyote header with a custom merge collector added to the end, performed much better then the expensive Kooks setup I had before. Many name brand headers, Like Borla, have no collector at all. I dont see what the gains would be from a system like that.

I never know what to think of YT content creators as far as technical merit, but this guy says they found no difference in a supercharged engine-

Palm Beach Dyno says they’re worth about 2% on a supercharged combo with high mass flow-

So- not a huge improvement by any measure.

Super charged engines are much less sensitive to exhaust as long as there is sufficient flow. You are basically blowing the exhaust out with boost. When it is most critical is with N/A builds where scavenging is used to help pull the spent gasses out. Sizing the primaries correctly and proper collector design is key. Bigger is better doesn’t necessarily apply here.

 

[Midtownz06]

The best scavenging exhaust collectors taper down quite a bit right before the merge. It’s kind of a cool theory that the compression of the gas at the merge followed by a rapid expansion allows improved scavenging

Think of it as a Venturi.

 

[Midtownz06]

Picked up 11hp on a Venturi merge collector on this test 20 years ago.

Inconel cup car collector. 3" choke to 3.5" outlet

Hi FlyHalf

Ive been reading your great build thread(and others) with much interest and tried to send you a PM but unfortunately im a rookie and are not allowed to send messages if not initiated by a senior member!

Im building Mustang versatile track car over in Europe and would be very happy to get a little of your input if you have time.
Could you please send me a PM/message so I don't have to mess up your nice build thread!

thanks!!

Regards Pete

Pete, another idea would be for you to start a thread to get feedback and just tag @flyhalf and ask him to chime in publicly. This would be preferred because, though some like to discuss things privately, it helps the community when tech advice is discussed publicly. Others in your situation can benefit from a lot of that same advice. It also helps you add to your initial post count so the community gets to know you - which is key for a community like this. Private messages have their place for sensitive conversations, but using them for tech advice does a disservice to the rest of the community. We actually want new members discussing things publicly.

I'm good but not that good lol
So community help is the best!
If you are on Instagram It might be easy to communicate.
If so. DM me @ italian_stang

You have a lot of great experience that Ive been impressed by, but ok Ill create a build thread of my own!! ;-)
