First take off run
Discussion
Today, I've owned my Cerb for a year
.
I rarely tax my cerb and have never hit the rev light as I have too much mechanical sympathy. I tend to concentrate on smooth and fast rather than straight line drag racing.
But a portch 944 really pi**ed me off today by cutting across me on M25/A2 slip road.
So after one year of slowly getting used to cerb gearchanges and gently nursing a fifth gear syncromesh problem I decided to give her everything from 20mph in second to fourth gear.
Now I still didn't hit the rev buzzer but I was close as dammit to 7K in gears before changes.
I think the portch may have damaged his engine as a big cloud of black smoke came out on his first gear change, although he may just have hit his rev limiter.
Cerb accelerated sooo fast that it disappeared into the future for a few seconds before returning to the present day, and job done on portch.
But the reason I'm telling you all this, is that the fifth gear syncromesh problem I have been carrying for near a year has now dissappeared!!!!!
Not even a gear I was using on acceleration, I just don't understand why.
Previously any gearchange from fourth to fifth over 3000rpm would have to be matched almost rev purfect to achieve a non crash gearchange.
Now I can leave a 500-1000 rpm difference and you can hear the syncromesh pulling the revs together.
I have the only cerb which gets better rather than worse.

Clearly it's been feeling unloved all year.......
...........now it knows that you really do care!!!

Not sure that's all that sympathetic. I agree that revving the nuts of things can damage them, usually stressing con rods & g pins to hell, but if an engine is properly warmed up, going to the rev limit occasionally is actually better for it, I seem to remember reading somewhere:
Reason: at high rpm, the piston/con rod assembly stretches a bit further at TDC, and stops a ridge building up where it wasn't intended by the engine maker. These ridges can cause a hot spot, leading to pre-ignition. Well, that's my excuse for revving the nuts off the Cerby every time, anyway

Remember also that you need to check the operation of the change up warning light/buzzer.

I dont think I've ever been over 5000revs in Trev. The noise becomes so loud at that level (compared with every other car) it feels like the engine is going to blow up or something is going to brake! Plus i feel totally out of control when I get to that level of revs anyway and that the back end is ready to jump out.
The cars almost got too much power to use.
I cant comprehend what 0-60 in under 3 seconds must be like. I still dont reckon ive broken the 5 second mark yet.
Any others out there have similar views?
I've had trev for 5 months now and I guess they've all been kinda wintersh months. Roll on Summer! oh and new rear tyres no doubt!!

Nope, I love the explanation Tam, but not sure I believe it
If an engines gonna give out it'll be when its at its highest revs in any particular gear. The stress of an engine increases disproportionally to the revs.
I find very little reason to use those revs in real life. I rarely go for the destroy the opponent contest I did earlier.
My favorite manouver at traffic lights is to sit in a lane that would normally be turning right or left. Pull away only fast enough to pull in a carlength in front of the car I'm beating, with me, and especially he, knowing theres nothing he can do about it, but still dangling the cherry so to speak.
Its soooo satisfying if the car your about to do it to knows what you're gonna try before you start.
Besides, who you'd you rather buy a second hand car from, you or me?
Another brain frazzler is: was it the acceleration that cured the syncromesh or the year of careful driving after the car had been abused by its last owner?

You need to attend a track day,
to
guaranteed. On the road I have to agree, hardly ever
took the Cerbie over 5k. Julian64 said:

Reasons to be cheerful:
1) Engine note sounds glorious above 6000
2) Engines on performance cars are wear items. If I blow this one up, we'll just have to build the next one lighter, better balanced & stronger.

Nah, I prefer letting them get three car lengths in front, so they get to bask in misplaced triumph, before the inevitable

1) It would take a biggish crowbar to separate me from the Cerb
2) What, you find that regaling punters with miracle self healing transmission stories will make you that much more believable a seller?!

Jamster, not sure if this was a typo, or if someone fed you a right royal line when selling you the car, but it will not do 0-60 in under 3 seconds unless you've had nitrous fitted, or it's really a Suzuki GSX-R1000 (with turbo)!

ah ha! was actually reffering to the other motors like the new bugattis and chryslers that are spec'd up to do 0-60 in 2.9 secs. Was in last weeks issue of 'Nuts' magazine.
Imagine how strong your neck needs to be!
