Mr Brannen

Mr Brannen

only 18 bhp

Alps Pacino

18bhp from an na car is a decent gain, remember you cant just increase the boost pressure like a cossie

Maxfield

Thats quite alot to say the engine is already at over 100hp per litre.

OldDan

It's an NA car though, it's going to be hard to get much out of it?

I'd imagine bmw are getting pretty much the most out of the engine they can anyway?

Mr Brannen

thats what I thought

big_wig_074

i would go the other way and say 18 whole bhp?thats quite a lot!

Mike1

Look how much extra power BMW quoted for the CSL - around 17bhp?

Seems easier to get extra speed via handling and weight reduction/sticky tyres

Stavros

only 18bhp you messing about?
18bhp from a n/a engine just from a chip is pretty incredible TBH, esp one thats already mega highly tuned

Mr Brannen

you edited your post Stavros

Stavros

cause i realised it wasnt some spacco kid who said that, so thought youd be pissing about? as 18bhp is at least twice what id expect.

I remember Stu posting on here that they benefit quite well from a pair of Shrick cams couple of other bits and a live map.

If you look at the 330d on MSD's site, you get an extra 30bhp and an extra 40 torque, probably down to the fact that it's got a turbo they can play with

Then on the other hand, my mrs's puma 1.7i only gets an increase of 10bhp. so i'd say 18bhp out of an N/A is bloody good going!!

Can't see what i can do with mine as the Focus 2.0TDCi isnt on the site They gets 30bhp out of the 1.8TDCi 8v though

Mr Brannen

Thought it wouldnt be that much,a bloke up here reckons hes got 415bhp outta one

BigMouthBillyBass

The new M3 is meant to be a 415bhp V8..... maybe he's got his wires crossed/billy bullshits somewhere along the line

Unless he's got Nos or sumthin

Maxfield

415hp would be hard to get from n/a S54 you'd need

3.4 with high covmp pistons
Big set of cams
Carbon airbox with alpha n
Bit of head work
and a good full exhaust system

Stavros

and a miracle
