Hi does someone know what this car had changed to get 300 BHP


Engine:

Power: Evo 1 Ԛ—a 225 kW (300 bhp)@8000 rpm.
Evo 2 Ԛ—a 235 kW (312 bhp)@8000 rpm.
Evo Sport Ԛ—a 274 kW (365 bhp)@8,750 rpm.
BTCC 1991 Ԛ—a 206kW (275 bhp)@8,500 rpm

Transmission: 1987 5-speed.
1988 on: 6-speed.

Homologated Kerb Weight: 1987 Ԛ—a 960 kg.
1988 on Ԛ—a 920 kg.

Performance: 1987 0-100 km/h Ԛ—a 5.0 seconds, top speed 264 km/h (165 mph)
1992 Evo Sport: 0-100 km/h Ԛ—a 4.6 secs, top speed about 275 km/h (171 mph)
If the standard evo sport has 270% cams 2,4 L bore
and it gives 238 BHP on the fywheel
NO turbo ,NO supercharger
What exactely has been changed to give this Beast 300 BHP
induction kit ,exaust, ecu,
if it possible to give more details on it
that would be the best gift on new year ,for me
Happy new year to every one,
If you have the picture of this car ,could you send it to me , don't even know how it looks like
shame on me

Err......What car is it suppossed to be ?

Well, that's the unswer i'm lookig for .
All i know that this car was made somewhere in 1991 1992
for grupp A racing ,but what parts weree instoleed and by what team ,or garage ,i don't know , i'm just wonderind ,
if to change exaust it may give extra 20 bhp
ecu 35 bhp
induction 15
on the top of 238 from the factory but it on the flywheel ,it means that on the wheels it would be less ,.
so if someone hase some time to spare on stupid man like me please do so
happy new year

So it was a group A race car ?

Looks lilke it
and how much money needs to spend on this ?

talk about vague mate ,dont you have any more details?

to get 300hp
i think 292cams
carbon airbox
alpha N
group A headers
custom straight through exhaust
and 8k+ redline

Is Group A Touring/Rally Cars?

If so, you are looking at a R&D budget of about Ԛ£1m

Simple answer, To get 300bhp from the engine......spend loads and loads of money!

back in 1992 they didn't have all these gadgiets .so the team probably could spend around ??? for one race day on parts ?
but this car now still have the same engene that 15 years ago and to modify it ,we are talkin' around 3000 4000 Ԛ£ ore more?

Heres a 320Bhp from around 1993

stevetigger ,yep you are absolutely right but this car is the pure mechanic no smart devices ,and still can't immagin' to myself what exactely did they changed on that Beast

You dont need smart devices if you ave loads and loads of money!

Look at the new M5 engine, it has loads of power with no smart devices because bmw have lots of money to spend on development!

M3ben2005 has a group A car he thinks its around 360-390hp with 10k redline

to get 300hp
i think 292cams
carbon airbox
alpha N what is that?
group A headers ? complit new head or just modified?
custom straight through exhaust
and 8k+ redline

how much all it cost?
why im askin'
last april very good friend of mine got hold of 1990 evo 2.3 L
we have found it in Germany paid 9,000euros a that moment it was around 7 000 Ԛ£ so i took it for a ride and i realy like it the car has 180.000 kmtrs and recepits that 35 k ago uberholt was made overall engene rebuilt , that's why i ask about this car ,how to get extra 100 bhp without f**n up engene ,

i would of thought around 5k. Are you doing the rebuild yourself?

Mark ,thats my friends name
,he's thinkin' about something like this ,but we need to know how much to spend ,and maybe in the March i 'm thinking myself go to Germany to the lad we got This black beauty from ,that was his progect ,he finished it and sold it to Mark cozz he wanted evo 3 ,god demn germans

except double vanos
an ecu that a few years ago could have powered the space shuttle
a crank design never before seen in a production V engine
some very clever metallurgy allowing a prodction v10 to rev to 8250rpm
plus other stuff too i suspect.

i think evo referred to it as the most advanced road car engine ever made.


steves right to a degree tho.
with something like an older m3 s14 u need to throw money at it.
this buys some very trick bits and allows massive power.
but i doubt itd be too reliable.

Alpha N = engine managment
yeah new headers have a look on here
www.e30shop.de

still thinkin' standart is 215 bhp +
Engine Kit
+ 40 HP/30 KW
(2,3 l S14) Complete kit to increase power by 40bhp (2,3 ltr S14). Kit comprises cams, mapping on rolling road and air filter.

Available for all S14 engines. 3200,00 EUR

gives 255 bhp
+Race
Exhaust Exhaust for M3 E30. This Exhaust is equivalent to the design that was used in the DTM 1992 but to fit the stock header. A power gain of approx 7KW can be expected. Includes the X-pipe, which is essential for the S14. ID is 60mm. Two metal catalytic converters are optional (add EUR 300,00). 1600,00 EUR
Non-Cat
gives 265 bhp
but how to get extra 65 bnp
any idias ?

Cams 290?
Alpha N
carbon airbox
Or 2.5 rebuild?

dn808e wrote: but how to get extra 65 bnp

much much wilder cams
increased rev limits
larger tb's
possibly increased cr
possibly bored out

problem is with the cams i said about you probably wouldnt be able to use it on the road as its power band would be all high up with fcuk all below it.

You could use 284 with good realiablity

so after spendin' 3 grand all we gonna get is 60 bhp but it shoul be safe
enough ,how fast the car will be from 0 to 60 with 60 bhp more 215 +60 = 270 on the flywheel ,?
if after that it will meet 5.sec
i'm happy cozz
i went to the BMW Sorensons in King's lynn
and they gave me the price on the new engene 6000Ԛ£
so i rather wait for 3 months and go to Germany.
thanks to everyone who had patience to talk to silly man like me .

probably around 5-5.5 on weather condition and tyre

Dont think so.

Andrew

IMO you would get around 265 with that little lot, add a 2.5 conversion and you may get 290 - maybe??

But surely that kind of power will be at some really narrow band right at the top of the rev range with a spike of torque hiding elswhere????

Therefore driveability will suffer big style and popping down the shops will be a thing of the past???!!!!!

Or am i talking a big load of sh1te???

well that's the GOOD Q ?
FROM 215BHP I SHOULD NOT GO MORE THAN 65 BHP THAN.
if i still want it to be drivible?

Yes your right, id go maximum 270 for an m3 really. That would be a good combo of reliability, price and performance.

I think it could be achieved for around 4k, or maybe im well off!

I would imagine the 300bhp+ engine bay's would look similar to this (but this isn't an M3 lump afaik)

This is our group A car's engine bay, roughly 360bhp

Yeah right
Andrew

Think what u like mate, dont bother me

Well prove me otherwise, you have shown some pics of your dads car giving it the bigen and you have no technical specifications to back it up.
