M40 convertible turbo*update mark 3*

[randomdave325]

Hi dave how thing with you ?

Ant has done a cracking job Yes it is running MS so you can plug in, i dont know about limiter you would if to ask Ant .
Ant Said you got to stick something up the ass end to put it on RR, wide band i think

How is your M50 baby up and running again?

All good m8 thanks. busy!! which kinda keeps me out of mischief
i was just curious as to what management it was on. there's no need to plug it in m8.
Again with the limiter. is it any higher?

I started my car on monday for the first time since it's re shell. it had no manifolds on so fired into life with 6 blueflames and everything!! i took it to phoenix yesterday to have a manifold developed for 2 weeks then i'll be finished for run to the sun. i'm kinda lost without it now so have dragged that s50 from under my bench and am currently abusing my 316auto with it! come over if not busy 2mo. be good to see yours with a turbo and a hardtop. it'll be an brakes & a lsd next!.
developments hey. u gotta love em

[smithy318i]

Nice increase in numbers there Chris!
Plus good scope for more i assume

[CHRISP]

I am on the first step of the ladder Tony.

[Ant]

This setup will run 12 psi easy into the B18 , currently @ 6.5 to give 100% cylinder fill and 100% VE

more boost will give more HP up top, but less TQ down the bottom end.

May I have a copy of the plots Chris Please ?

[CHRISP]

OK Ant will send you a hard copes in post cant seam to be able to email them.
Car is running sweet mate smoooooth
Lots of interest at show gave out alot of your flyer mate.

[Ant]

Forgot about those dude

was gonna ask you to pass them if the Q came up, Cheers Chris

biggest question....... does she go down the drive any better ??

Just touches much better, clearing all road humps now going to get the JCB out for drive

figs well good mate and still drivable just what i asked for

[Ant]

DYNO ADDED

[CHRISP]

Thanks Ant for putting figs up .
Have you heard about ramp yet

[Demlotcrew]

That looks like a good curve.

But how comes yours is not getting 200bhp like malcs?

[CHRISP]

more boost will give more HP up top, but less TQ down the bottom end all usable and it pulls like a train

[Demlotcrew]

Yes but malcs has less spec and still has 200bhp

So why doesnt yours?

[tylerma]

mine hasnt been on the rollers yet
so we dont know what it has

[Demlotcrew]

Malc im sure i heard you say to people at ace thats its 200bhp?

[tylerma]

no way
I wouldnt claim anything that is not proven

our aim was 200 BHP

weather or not we reach that is another thing

[Demlotcrew]

Well going by what chrisp's car is putting out i think its best you aim for 160bhp

[tylerma]

ok

[Ant]

160 Hp for now maybe....

thats the real beuty of FI, want more, turn up the wick ( to a point)

if only N/A tuning was so flexable

[Demlotcrew]

Tell me about it Ant,

Im still only on 210bhp and 170lbft at the fly (175bhp at the wheels) and all my mates in and around cambs with FI are well past the 300bhp mark and they have spent far less £Â£Ã‚£Ã‚£$$$$ getting there!

Its not that NA is not flexible its expensive. But the rewards are far more than with FI.

No need for that Malc, im just being realistic your engine spec is less and you aim to get about 15% more power?

I think every engineer around the world would like to know the formula for this, you just might be on the verge of a break through?

[CHRISP]

Malc and my self are happy at the moment
Mine is 170 bhp Malc is turned up more so he must have more than 165 bhp i dont know how it works HP per psi

[snoops]

have any of you M40 turbo boys done the 1/4 mile? any 0-60 figures?

[Dave_M3]

I know its slighty off topic but how much do you reckon an M42 would give at around the same boost, or would it just go bang. Im intrigued to know a power estimate of what I'll have by the end of my modifications, plus people are asking me how much power do I think I'll have, when they realise I'm not entirely sure it only gives them more reason to say It wont work...

I dont think I'll have the expertise that has gone into this project though

Lovely install, and the fact its on a cab makes it that bit cooler

[Ant]

M42 would show slightly higher gains per psi of boost, purely because it flows more air and is therefore more efficient.

theres one Turbo M42 that i know of in the UK, he's a member on here too.

I'm hoping to do one of my conversions on an M42 in the coming months, be a PITA though as an R+D evercise the costs are to be carried by A-Tech

watch this space....

[antony]

a guy here in new zealand has one (m42, in an 318is). 165 rwkW @ 13 psi.


and he's selling it here: http://www.trademe.co.nz/Browse/Listing ... =102539106

[Andy335Touring]

165 rwkW @ 13 psi.

I'm lazy but what does that equate to in English ?

[Ant]

222 HP roughly Andy

260 or so @ the crank is about right, 1 bar in theory should double the claimed N/A output of any given engine.

Very not bad

heres a number i like ................. 436 bhp

[Ant]

Thats more than enough

[Kos]

Thats more than enough

true, anything more that 400hp in a RWD street car is usless. but 500bhp always sounds good !!

a decent turbo with usable power delivary is the key to have a fast turbo'd street car. the scandanavians use big turbos, but they are only good fot high RMP 1/4 abuse and are not drivable

[fuzzy]

i know how much trouble i have with traction and i only have 282bhp over 400 would be mad. 4wd would be a nessesity for that sort of power i think. i got a rough price for 4wd converting my e30 using cossie running gear and the starting price was from around £2500. one day .....

[Kos]

never had trouble putting down 265bhp before, but 3rd gear wheel spin at 90mph in the rain was scary.

[CHRISP]

just another mini update

visited Ant for some new mods
a wide band lamber sensor ,
a wasted spark set up,
and a bit of remapping ,now running 7psi



hope to get car back at the pod

[tylerma]

nice one Chris cant wait to take a look round it
