yet another fueling question

Quote from: gillard28;626658That walbro will flo enough for what you need.. i was running 20 psi on a heavy metha mix with this pump with no worries. the 044 is over kill.. if not go with what brian said

you dont need a pump that flows 8 bar so why use it.

This is going to go on for some time as i really don\'t rate them and have over 4000 good reasons to steer clear, so i\'d suggest you talk to the guy who\'s going to be setting it up for you and ask what he would recommend.

BTW, gillard, what hp did you see at 20psi (assuming it was on stock twins) how long did you run it like that? (The name change hasn\'t worked by the way

)

yeah well i got banned as sdminus

Ran it for 2 years up 18.5 then 6 months up to 20 psi with lots of methanol in the tank. as far as i know the car still has it in the tank.

I am not knocking the bosch pump it is very good. but it is expensive and like brian said you can get enough flow from a cheaper pump which will pay fow a few other parts. i did run that pump to hell and back with no probs and also some scoobys i tuned up to 1.5 bar also on td04 turbos with no probs. I think you can have a good system with a little pump if the system is good as a whole. i had lots of help from very good friends (gary gooding, brain ellis) which also helped if i am honest.

my advice is to stick with people you trust. thats all i eva did and i still do to this day. I had a rotary for 5 years + and never got close to loosing a motor and i tuned a few others as well. I think that came from having the right people in my corner

Ok sorry thought you where doing the "Tuner pretending to be a Noob" thing.

I get what you are saying but after having my figures burnt (btw i bought the Walbro from a well known tuner who also charged me a packet fit it) When you look at it as a Â£90 walbro or a Â£110 044 the cost difference don\'t look that bad? It may just be me but Bosch have been fueling Race/Rally cars for years and for me that means reliability which i like and its future proof (can build a nice fuel system from one)

All that said its just my opinion and i\'m still kind of in ore of your low 12 second pass on stock twins, all the Stock twins i\'ve played with give up and die after 1 bar for any period.

cool. no worries. it used to be more expensive or may be that was the motorsports version at the time.

Quote from: Grizzly;626654Anything you agree with then? The Walbro issues happened to me and they cost me an 4k so forgive me if i don\'t have faith in them.

Dude, it\'s teh intertubes, don\'t take it to heart - like I say - I\'m not one to just accept everything I read and like to explore more into things - I\'m realting my experience, liek you are relating yours - and I can totally udnerstand why you wouldn\'t be happy running one given your history with them!

FWIW, Walbro have been making pattern (and I belive supplying some OEM) parts for quite a long time AFAIK - they\'re pretty well thought of in the US too, Lots of people seem to jump on them because of the anti Walbro bandwagon on certain forums, without actually using them - although obviously in your case this isn\'t what\'s happened!

It\'s an odd one - obviously rotaries are a lot more sensitive to fuelling conditions, so it raises the question whethe there are dubious bouts of reliability from a fair few walbro\'s, you just don\'t see them on the average boinger until you strip the block down thousands of mies later.

Unfortunately at the time i was thinking more along the lines of don\'t believe all you read on the Net and the Tuners/Specialists have the last word, lets just say that doesn\'t always work very well.

Don\'t start me off on Over Bored injectors

Venom/Deutschwerks? Bluergh.
Out of interst, which tuner recommende the Walbro? Most seemed to advise the opposite when I asked!

They have been around for years (think they where first made for the RS500\'s way back when) and there are a few deals about at the mo.

I got mine second hand of a mates Cosworth and it was a bit cheaper then that
