A race bmw 316, m10, s14, m20, turbo, na, its been the lot!

some engine double injecting works for others it doesnt, best power usually come from having injectors external to an engine, best throttle responce from having then very close to the valve, double injecting tends to give you the best of both, it also allows finer control on the fueling, because you can use smaller injectors,

on my 2.0 8v we gained 12bhp @5,000rpm

running an 8 injector setup also means you can use std size injectors from a car with about half the bhp you are aiming for, much cheaper than buying a new set with a big flow rate, but you do need to make a second fuel rail, and not all injection systems will support 8 injectors.

Overal 8 injector is best in my view, potential for more power, cheaper injectors, and its a little bit different.

I agree. I need some injectors for the YB but as you say it seems cheaper to find 8 injectors that are an oe fitment than 4 that would work alone on a race engine. I think I have a spare rail and my DTA supports 8 easily. Plus fitment in my bay would be relatively simple


Any more progress Graham??

Re: A race bmw 316, 240bhp Atmo M10 now going s14 power!

a little

exhaust manifold and water rail are on, doesnt sound much but i had to modifiy one of the secondary pipes and part of the system

Re: A race bmw 316, 240bhp Atmo M10 now going s14 power!

a little more, oil tank and pipes in,




connected battery hit starter button and a big fat nothing!

ponder ponder, remember to fit engine earth strap and she cranked, some more cranking later and we have pressure




55 psi on the starter not bad going, ok theres no plugs in it, but the battery was far from fully charged

Are you going to make some noise later today?

[Graham]

Re: A race bmw 316, 240bhp Atmo M10 now going s14 power!

hopefully, it should just be a case of plugging everything in, the map wil be a milliion mile out but it should still go

Re: A race bmw 316, 240bhp Atmo M10 now going s14 power!

no pics but it does run, just need to sort out top hose plumbing so i can get it properly upto temp

Congratulations! Yet another one sees the daylight!

Was the map badly off? Did it start okay or sis you need to tweek it a bit?
Are you happy with everything so far?

well done good show, when is it booked in to the rollers to get it mapped?

not even touched the map! i've not even plugged the laptop in to the ecu i know the maps miles off but i've started so many engines on totally wrong maps i was sure it would run, it took a bit of persuading on the throttle to first go, but now its on the button, i've not even had a screwdriver to the tb's!

although the last two things explain why it idles fast and pops back, although will rev cleanly with a blip, i generally dont ever touch the maps, as long as it starts ok and idles well enough i leave alone because daves only going to change everything anyway!

rolling road is on the 16th

Re: A race bmw 316, 240bhp Atmo M10 now going s14 power!

looking forward to the 16th

me to sort of, theres too many compromises for it to make really good power, as long as its healthy i'll be happy

Re: A race bmw 316, 240bhp Atmo M10 now going s14 power!

Well done Graham

Fingers crossed for the 16th.

Good on you Graham, that is a very nice engine, it will have a truck load more torque than the 8 valve did lol
The m10 was a very quick 8v 4 pot but the S14 will really get that E30 shell moving fast

Best of luck with it
