has anyone used tis on the engine?

was looking through demonn tweeks and see the ad, seems to do the job well!

are they worth the money? and hassle to fit?

 

do YOU think it'll be worth the hassle? where do you think you'll gain?

 

I suspect if they were that worthwhile then we'd all be using them already, however the principle seems sound just like using an electric power steering pump ?

 

Dave Walker has used these on the cvh and i belive there was a measureable difference in parasetic losses. Also at high rpm a distinct flow improvement. Ill see if i can find an article.

 

Be fine till you get a flat battery lol

 

... and the ECU, Fuel pump, coil fail

 

Iv got one and there definatley worth getting, Easy to fit aswell.

 

Sounds like a plan.

 

are these not the electric pumps that pump after teh engine is switched off, to aid cooling? same as on an Audi TT etc?

 

an electric water pump with proper control has many advantages, but the flow rate must be high enough.

 

what should the flow rate be any ideas chap? the engine is out of me car at the mo so will have to have a word with the fella building it see what he thinks


cheers lads

 

at least as high as the original belt driven one at a nominal 12v supply.

 

Great idea really, wish id got one for my cossie really, just didnt think about it at the time of ordering my new pump.

With an electric one it can be controlled based on what the engine needs, not just vary with RPM in a way that doesnt really suit whats needed.

 

and you could run it just before switching off and it can be left running after the engine has stopped to cool down the turbo.

 

The EWP ones seem to be best......

 

yeah but water flow thru the turbo carries on after you switch off anyway, due to the effect of the water boiling in the water jacket and hot air rising, vacuum caused by this etc. etc.

 

water flowing in the turbo isnt what you need anyway, its oil to be honest.

 

The EWP ones seem to be best......


thats the one im was looking at,


jsut so you know me turbo is not water cooled now

 

BTTT for anyone with experience of using these.

 

I read that article and the dude in CCC mag saw gains throughout the rev range. I'm sure he got 5bhp at the top end. If remember rightly he used a 1.4 Clio cam belt which was the right length and type. if I'd have kept my S2 I'd have done that and gladly taken the 5bhp fankyou very much!

 

saw gains throughout the rev range


that sounds good, anyone else used or heard anything good and bad

 

Used a belt why ? there electric ? I just took of my water pump, used blanking plate with the right outlet on, and plumbed the EWP in and wired
it up. they are very very efeiciant, mine is on a switch so i can get it up to
temp a bit quicker aswell .

 

tiny, Shorter cam belt, no water pump pulley What engine is yours on and is a pre-made blanking plate avalible or DIY?

 

ive seen someone run one of these and all he did was remove the impeller of the pump and ran a standard cambelt

 

Mine is on a tvr engine in a saph and i did actually just remove the impellar
open it out slightly with a die grinder, then got the hole welded up . I did
have a blanking plate diy job but didnt use it, but all the angles and reducers come with the kit to simply plumb it into the system.

 

shop around before you buy from robin tweeks mate

 

 

Think automotive do them a lot cheaper than DT

 

DT are a major rip off

 

thats why alot of us down here call them robin tweeks mate

 

Demon Thieves!

 

well after all i have spoken to tommy field and he suggest i dont use one



thanks for you input thou chaps

 

What were his reasons Gus?

 

i hardly use the car so he said realibility would be a problem


basically i have no worries with what i have got so he said that for the trouble it would be to mount and stuff it would not be worth it


he has used a couple before on zetec engined motors and said that they work really well, got good results from them but reliabilty once again let them down

 

Gus, any chance of getting more info' as to why they failed please and was EWP asked to comment on their failure?

I don't understand why they are unreliable!

Great to hear of other peoples findings

 

hey, TINY, are you from the mids near dudley with a white saff?

 

No m8 im not, i live in Ruislip middex
