612 question

George- Torque peak is above 5000 rpm, but there is still plenty of torque below that. 2000 rpm is only about 30' on a start. The 612 is geared like a drag racer compared to a Z06 Corvette, but weighs 1000 lbs more.

 

not at all - mine gets up and goes - and wants to go all the time

 

Not my HGTS 612 - When in Sport Mode, it storms out of the gate so fiercely, I get slammed back into the seat with alacrity.

 

My HGT2 has plenty of torque

 

Not at all, mine keeps up every bit with my 599.

 

I loved the acceleration of my 612. I had a Maser GranTurismo Sport next to her, and though by the numbers 0-60 they're similar, I found the 612 far more exhilarating for whatever reason. I loved that car. A dog it was not. Only time I could see it being an issue is passing when you're cruising in 5th or 6th and need to downshift a couple to get your RPM's back.

 

Bob, totally agree with you on this one.
612 should be pretty lively and go through some great rev transitions as it heads all the way to the redline! Never felt it is a slow revving car...

 

my 612 is awake and goes off the start.....
Commenting about dropping into 1st... Brakes are much cheaper to replace then a clutch.... She should be driven like a manual... Only use 1st to startup.. never downshift into 1st...

 

I never dropped to first in my 612 or in any of my fcars, but I do tach it out. People say just use 1st to get rolling, but my clutch readings suggest strongly that whichever your flavor, using 1st to 7k doesn't hurt anything anyway.

 

No mechanic here, just curious, how old is your 612 and have you made sure the injectors are clean, plugs fresh, etc?

Most of us given the opportunity will coast into stop lights and such. It doesn't make much difference for the clutch but the trowout bearing is a relatively expensive repair as well and you don't want to have to change it when you're not doing the clutch, too.

 

Agree with Piper on both points.... About revving to 7000 I thought the sales bonus of the F1 tranny prevented over reving.... I never attempted to over rev I usually shift when she gets to 6k, but do you know if the ecu would prevent the over rev condition?

 

Yes it stops over revving - have done it a few times accidentally
Also, I downshift to 1st all the time on all my present and past F cars and never had a problem - love the sound - I might be considered an aggressive driver

 

Funny thing is if you screw up by putting F1 into neutral (expecting to stop) and end up not needing to stop, F1 will usually put you no lower than 2nd gear when you upshift to make embarrassing recovery to continue on.

I'm curious if anyone is aware of the protocol for Up-Shifting F1 from Neutral whilst moving at a forward speed. I'm sure the sport setting probably effects the gear selection as well.

 

Adam- No difference in gear selection whichever mode you are in and both the up and down paddles give you the same gear. The trick is to use the downshift paddle to get a gear and then hit it immediately to get a usable lower gear. Works like a charm. In rare cases, you may have to hit it twice after the initial move from neutral.

 

Bob, agree with both points

Acrisis, next time the car has a service I would get them to check it out.
I'm no mechanic either but it does sounds like it is more sluggish than most of us experience our 612s so maybe something is a bit clogged?

 

Yes Terry!
But why does the F1 always reselect too high a gear when you re-engage it?
I always think that's a bit of a strange quirk in the software...

 

Nick- It selects the highest gear in which the engine will run smoothly. No clue why, it is just mechanized that way. I am good on the hows, but not so much on the whys, which are anybody's best guess without talking to the engineers. I doubt even they remember, since the decision was probably made in 1997 or so for the 98/99 F355 and never changed.

 

It might be fuel related. My 456 started to display similar symptom when the rubber hoses started to corrode and fill the fuel filters/ fuel system with small pieces of rubber, probably caused by the amount of Ethanol in the petrol nowadays. Hopefully it won't be this but I would get it checked soon than later.
