what engine
what do you think would be faster with both engines standard.
in a book chassis say 450kg
a couple of mates said the audi and a couple said the bike. so i dont no ive never been in a bike engined car but i have a pinto and that was fast.
what do you think about the top end power aswell.

Well, the audi engined car would be heavier, but the CBR1000 is an older engine.
Depending on the level of tuning, it'd probably be a close run thing. If the audi is the higher power 225bhp version, or has been breathed on
even more, then it'd probbaly be faster.
Out of interest, is there a way of getting the audi turbo unit into a se7en? I'd be interested in that myself!

the audi engine is already rwd so i wouldnt have to mod the sump. and i was thinking about the turbo because thats what ive always driven. you just
cant beat the feel of boost lol. ive cut the flange of the audi gearbox its alloy. so i can make the housing. i was putting it in my saxo but i cant
make my mind up lol. ive measured the locost chassis iam making and it will go in easy. i dont no if i would need a bonnet mod as i havent bought it
yet. but iam ordering a panel set next week so i will soon find out.

The main thing about a BEC is it has a chance of weighing 450kg. Unless you're building from exotic materials I really doubt the Audi would get
close. More likely 550kg in honesty.
Beware big boost in a lightweight car, it will either spin up the wheels or put you in a ditch (possibly both).

The Audi unit would easily be 100 kg heavier than the BEC what with intrcooler, turbo, larger radiator, heavier gearbox et al.
That would equalise the equation significantly.
However it will be much easier to cheaply and reliably gain another 100kW with the Audi which would put the equation firmly in the Audi camp - and yes
it should be no problem to fit.
As I have said before rather go for a Volvo T4 motor which should be much cheaper to source as it's much less in demand and is stronger and
possibly lighter than the Audi motor.

neither ,
NA 5 pot volvo motor .
170 bhp , 6700 rpm .
of course the turbo will fit aswell .
all in my opinion of course
the BEC will be simpler to build in the long run , once you add all the paraphanalia , it gets expensive to keep it under the skin of a seven bodywork
.
things like intercoolers like to be big to be effective , if you start turning up the boost .

well Ive got a busa at the min and im doing a conversion to a saab 900 HPT unit, the whole car cost me £250 and in the car you get 185 bhp, with a few
changes ie. injectors/ecu you can easily get 300 bhp check out maptun's website, they have quite a few 900's or 9000's push anything
out upto 600 bhp  for me its a really cheap conversion

Personally I'd go for power:weight over absolute power.
The shed-like aerodynamics of the Se7en make a theoretically stupid top speed unobtainable and more power normally means more weight- its often a
viscious (descending) circle!!!
Then again, last night I was thinking about an Audi turbo engine in a Fury

i went for the 2.0 hpt as its more revy the 2.3 makes to much torque for a 7, ive been told a 94-98 year saab 900/9000 engine will take upto 500 bhp
with no internal mods  so if its not quick enough with 300, theres always room for improvement
