355 race

What makes me laugh is that your 328gts, Testarossa, and '76 308gtb that cost "so many times more" will probably lose to a mustang every day of the week.

 

Uh, I would LOVE to see a rustang keep up with a TR up to 180+mph

 

Don't you get it yet? Nobody cares!

OBDIO-I ECUs allow a richer mixture, a less restrictive intake, and an less restrictive exhaust.

 

Don't dump the clutch. You don't want to shock the tires with a sudden jolt of power through the drivetrain and make them spin, you want to slip it (fairly quick in a Ferrari so as not to bog) come in with the gas a bit quicker than you're letting out on the clutch. Just takes practice. I find it kind of funny that launching a F355 can be so bad for the car. Isn't it built for performance? I would hope that the drivetrain of a F355 could take more abuse than the drivetrain of a $20k Stang. (but it IS a track car, not a drag car)

With the Mach 1 being an auto, he will have to do what is called "powerbraking". He will hold the brake, come in with the gas to hold the RPM at ~1500 or so then will release the brake and come in with the gas. Auto's are capable of very consistent and quick launches, but once he get's going, the Ford auto will be slow and soft shifting.

I am confident that you will take him in the 1/4 and on.

 

The issue at hand is TQ, the big cube motors have TQ down low in the RPM band, so they can spin the tires at 2,000 RPMs from pure TQ overcoming pure weight on the tires; that is no/low clutch slipping. At 2,000 RPMs they are only making 1/3rd peak HP (RPMs are low) so the amount of heat disipated in the clutch is rather low.

In the F355 by launching near peak TQ (4,000) you are already at 1/2 peak HP so the clutch is being heated by a lot more heat than the big cube engine.

So, given the same engine power, a big cube engine can launch with lower stress on the clutch than a small cube motor of equal power. Counterintuitive!

 

Good point

 

Just a thought, but slipping the clutch at 4000+ rpm and full power is the best way I know of to ruin it. Better to dump the clutch, the tire spin you get depends on the rpm. It will PROBABLY spin at 4k, but drag strips are generally much stickier the street pavement. If the spin is excessive, just ease out of the throttle a bit, just enough to get it biting again. Don't let the revs drop though, if it grabs your all done, the first 60 feet are everything. Also about 8 psi in the tires, as much as 12 8 scares you, but with street tires 8 works pretty well, and will cut as much as .5 second off your time. If you've never launched it hard before, you really should try it a few times before you get to the strip, it makes a difference.

 

I call BS on this thread. I already know the result. Said mustang is bone stock, but no matter the launch rpm on the 355( "I tried launching at different rpms") the stang whooped my ass EVERY time. LOL
Allen is tongue in cheek as we reply.

I still say the 355 will take him no problem, If he still wants to run take em on with the diablo and give him a car lengths head start that will surly make his stang feel fast when he see's a white monster pass him up.

 

allenlambo if its stock (the mustang) you should have him little problems. But the whole comment about driving in a straight line is B.S. is not true. Depending on how you launch, shift times, missing shifts, powerbraking, you're 1/4 Et's can vary by more than a second. A poorly launched Ferrari 355 may not have enough low end torque to make up for a bad launch, whereas the Mustang's 4.6 will not only launch well from a powerbrake, but also shift consistently. Practice the launches, (don't bother heating up tires, it won't matter unless you run slicks, and launching a Ferrari with slicks from a clutch drop could be fatal). And for under 5,000 dollars in aftermarket goodies that Mach 1 may destroy you in the 1/4. (Even though its chassis dates from the Carter administration and the convertible has the rigidity of a wet noodle)

As a sidenote, there's no need to insult other's cars, everyone would love to have their dreamcar for one reason or another may have to compromise. I have a Replicar Cobra with a Supercharged and heavily modded Mustang 5.0 that I love just as dearly as any Ferrari, and it runs 10's in E.T.s without NOS and is driven daily.

 

haha, film this race dude. Why don't you just casually take off so there is no error at all on the launch and that way you will be sure that you have the tires gripped so you can just stomp it and smoke his ass. Either way, crazy launch or not you should win.

 

8 psi ?! LOL. You don't even run that with slicks or drag radials. Just run a few PSI under what you usually run on the street. Lowering the tire pressure in street tires doesn't do a whole lot of good because it is the flexibility of the sidewalls that really make a tire grip the road in a straight line. I would imagine that the low profile tires you have on the F355 have quite a stiff sidewall. Don't dump your clutch, slip it. Dumping a clutch puts a lot more stress on it than slipping it. That's how a lot of people blow their clutches up, not by slipping. If you don't hook when you dump it then you're fine, but if you hook hard with a 4k clutch drop, that's not very nice on the transmission. I'm pretty sure you will just spin and then bog if you dump the clutch like that, then you'll have to get out of that hole in the low RPMs and he will have put about a car on you in the first 100 ft or so. Your clutch isn't just going to die if you slip it this one time. If it does, then that's pretty sad.

 

My old engine was making 304 rwhp, so about 20 less than Allan thinks his car is making, they should act pretty similar, I was launching it between 4000 and 4500 depending on conditions, I did probably well over 100 launches with no problems. Slipping the clutch it the fastest way to leave the line and almost all drag cars are doing it these day. BUT they are doing it with slipper clutches that use either carbon-carbon or ceramic parts. I just installed a carbon-carbon to try, the ceramic is quite a bit cheaper, but I've never seen one suitable for street use (although I think I read the porsche has one). I seriously doubt that a stock ferrari organic clutch has many more than half a dozen slip launches in it. The problem as mensioned earlier, larger displacement engine make more torque and leave the line at much lower rpm, so there is much less heat generated by slipping the clutch. At 4000 rpm, I would give the clutch no more than 30 seconds of slip time before replacement. A kevlar clutch (like the one I just ruined) will not tolerate even 1 launch if it is slipping, it doesn't melt, but glazes the pressure plate and flywheel so it won't hold motor torque any longer.

Yes, I do run 8 psi at the strip with street tires. It is .2 seconds faster than 12 psi and .5 seconds faster than street pressure, although that may vary with tire brand though. I'm just telling you what works on a ferrari.

 

Good points about the different types of clutch material etc. I was wrong, doh! What kind of tire/what are the dimensions? I know in my 275/40/17's that 8 psi would make mine look nearly flat. That's awesome though that you have had quite a bit of experience at the strip with the Ferrari.

 

What's with these posts on proposed races - I just want to see the results! Not pages of bench racing.

 

WHEN IS THE FU*CING RACE ALREADY???? Too much advice, too little tire squeal. Make an MPEG and share.

It's pretty obvious that allen will purposely throw the race just so that he can come online and rave about what an old heap of crap a ferrari is and how much he wishes he'd been driving his lambo.

 

The funny thing is that I own a brand new P C4s (factory specs claims 0-62 in 5.1 seconds and we all know that porsche always tend to be conservative when publishing 0-60 or 0-62), and my Testarossa is faster off the line and at over a hundred the Porsche stands no chance, but then again I can do wonders in the track with it that I can't do with the TR. By the way I don't care about street racing or 1/4 mile races, any idiot can go pedal to the metal in a straight line, theres no real skill. And if I cared then I would be running a 1,200 hp, twin turbo and supercharged Testarossa by Koenig anyways!!! Eat some pizza and try to relax.

 

A '88 vette was 0-100 in 16.4 seconds and a '88 TR did it in the 10s, I think it was 10.9, anyways the 1/4 mile is a easy 13.3. I think you had a slow TR or something was a little off.

 

Dude, you don't know what you're talking about. Either that, or you never learned how to drive your TR. Sorry. Its true.
