Saab mention a limit for fwd, can't remember it now, but they should know a thing or two.
My calibra would spin up in 3rd in the dry when boost came in. Turbo and fwd isn't suited, NA fair enough is easier to get it down, but fwd is 3rd choice behind 4x4 and rwd for a reason.
With a lsd and rwd I can put 300 bhp down in the wet fine.

I agree too!
The Front wheel drive cars, during on hard acceleration, start loosing traction while the weigh transfers to the back...
Just like the guys before me said, it's not bad at all owning e.g. a 400bhp FWD Calibra ;D ;D, but it's a car that won't be drivable and safe.. by the way (i would say a good point of it) this power might be useful while overtaking at high speed roads  ;)

I understand what you're on about, but what you are talking about has to do with racing, hard accel from a stop.  If it's too much for you (I mean the average person there), then let off the gas a bit, that's all.  I preffer RWD cars, but the cally just doesn't come that way, and the turbos are just too hard to find in good condition.

and I do know a thing or two about cars and racing.

Actually, I don't think that we're as far apart as the previous exchanges suggest.  "If it's too much for you... then lift off the gas a bit" is always true, however much power you're talking about.  My point is that, however skilled a driver you are (& I draw a distinction between 'skilled' & 'good'), there comes a point at which you have to 'lift off the gas a bit'.

A skilled driver can feel where that 'point' is for any particular set of circumstances and make allowances for it - from your experience of 'cars and racing' I assume that you're in that category - in a fwd car this comes sooner than in a rwd or 4x4 car.  In a fwd car, with over 300bhp on tap, I reckon that even the most skilled driver can't really use all that power fully, but has to lift off before he's reached his own limit to steer a car through a bend, or other hazard.

It is always useful to have slightly more power than you need, or can use, so that you don't have to drive on the limit of the car's capability, but there is also a limit to how much excess power is worth having.

Agreed.  The only real use a FWD car has with a lot of power, is for accelerating at higher speeds.  Corners and such, much rather do it with rear drive, or AWD, but would preffer RWD in cornering.  FWD will loose traction quick in a corner and send you in an understeer straight for the ditch/tree/wall, if the pedal isn't worked right.  Witnessed this one happen at about 110MPH to a buddy of mine, luckily he was ok (But he entered the corner much to quick)

hi,
i'm workin on a v6 se9 at the moment. is the f28 a worthwhile mod with the v6? any great difference to acceleration?
want to frighten a few of my mates ricers without spending an absolute bucketload of cash! tall order i know!

i'm asking if its a worthwhile mod to improve acceleration or if i will spend more time changing gear than accelerating....? ie would it improve the 1/4 mile time/0-60 time etc.
i think the f23 has really really long gearing and if i remember correctly the f28 has the same 5 ratios as the f20cr but with another on top. dunno about the final drive if its the same etc?
basically anyone done it and what do u reckon?
what ricers my mates drive is pretty irrelevant, gonna get humped by a integra dc5 no matter what!

New astra OPC is a turbo FWD with 240hp...
I'm sure about some grip will lose in lower gear ratios but with modern TC you can have a good grip with FWD hi output engines.
Maybe using an entire programmable ECU you can implement a better TC.
Did the V6 throttle body is electical or is it with thye cord.
If it is electrical, e new ECU might reduce the throttle position when wheels spins

with regaurds to this fwd buisness surely if we wanted it to be quick at the lights we'd buy the 8v or summit simply because the v6 weight is against it all the time so take off will be crap anyway, or it could work in its favour because of the wieght either way what difference does it really make all have pros and cons just thank full they did make the callys with different engines to suit all, i dont believe there is the best engine of all (rant over)

OK first to use the F28 you need a LET flywheel which (if you get a lightened one) will shave 10kgs off the rotational mass, making the engine rev more freely.

Having an F28 completely changes the fast driving characteristics of a V6

When I had the 2.5 and the F25 box, I'd have to almost redline in second and shift to third, but the gearing would still drop the engine revs just below the powerband.

Yes the F25 third tops out @115 ish...  the F28 third is @85

Image copyright V6calibra.com

Look at the ratios between the two boxes....
A standard V6 with a F28 will always out accelerate a V6 with an F25 from a standing start.  A lower gear ratio effectively makes the car 'lighter' to the engine, giving quicker acceleration.

Ask any V6 owner who has an F28 if they'd go back to the F25 box......

You know, back in the 80's Chrysler build some racing cars based on their fwd coupe at the time. The cars were doing well against rwd v8 machines and even took the iroc sponsorship away grom the z28 to the dodge daytona cars.

The racing cars had bigger / wider wheels and tyres on the fronts than the rears as well as differnt suspension settings. Would that make  a difference on road cars..??

(mind you, it was the early experimental days)
Drives: an original SE6 auto, 93,000 miles (approx) and still going strong......(but some work is needed!).
