200+ Bhp in FWD cars

I thought torque steer was just the result of one wheel spinning, and thus losing lateral grip as well, causing the other tyre to pull the car round?

no, if one wheel did this in a non-lsd car then you'd simply loose all power as it all went to the spinning wheel

on a lsd car, this would make the car pull one way or t'other - which is part of what destroyed the focus rs.

Ive got a fabia RS with circa 190bhp and 320lb/ft..
that doesnt torque steer... (well it does at the moment as the whishbone bushes are FUBAR) altho itll light up the std (michelin) tyres in 1st and 2nd in the dry, and 3rd in the wet... its much better now ive got decent tyres on it, but still demands a bit of respect on the throttle, especially in the wet.

Wasnt it Volvo who originally said that 170bhp is the most a FWD chassis would take??

granted, RWD is more suited... the BMW 130i has what... almost 270bhp? and ill bet it would whip any FWD car on the twisties... but at the same time, if yer "average" 200bhp hothatch was RWD, im sure yer average chav would be more likely to stack it! - i would like to think im a ok driver, but even the thought of a similar powered car in RWD scares me a bit..

One of the odd things. Torque steer has nothing to do with torque. Power has vastly more of an effect than torque.
Also, FYI it was SAAB (makers of 250 BHP FWD cars currnetly) that said 170 BHP was the FWD limit

Im not really into cars but have learned some interesting stuff from this thread.
so thanx for a nice legible thread.

btw i havent even got a licence lol.

i have seen a insane civic with 500BHP... it had a teg type R lump in its bay mind... they reckoned it could eat skylines i don't think so LOL. also it had 200BHP of NoS tut tut...

[herulach]

It might do, assuming its set up right and not just a dyno queen, most skylines you see arent that fast, well, nothing like as fast as their rep would make out anyway.

I never quite got how they rate the nitrous either, cos you cant make it give you 200hp, well you could, but only at 1 very specific rpm, it depends when its on. 200lb/ft i could understand.

in theory 100BHP nitrous is bout 30/50 actual power output aparently.

The reason it works that way is that if you inject a specific amount of extra fuel (with the nitrous) you get a specific amount of extra power. It doesn't matter where you are in the rev range because that extra fuel is always getting burnt.

And yes, that does mean that if you hit the nitrous button at low revs you can end up with a massive amount of torque being produced, enough to break engines/gearboxes.

Yeah, thats my point, you cant rate it for extra horses, just for extra torque, since horses are dependant on rpm, so putting it in at different rpm gives you a different horsepower boost.

Maybe i should start selling 200 shots on ebay, that are actually like 1lb/ft and have a little disclaimer to the effect that if your engine cant hit 100000rpm its your fault not mine.

hehe exactly, but like it be well fast b4 it blows engine innit [/chav]
LOL

Nope its more consistent with horses as an X HP NO2 Kit will give a lower Torque boost the more RPM it is used at. The HP is roughly constant. However all of the kits seem to exaggerate the claimed figures.

Any bhp figure is rpm dependent. No different from if you're measureing an N/A car for an increase from something like a change of cam profile.
