need more fuel

done a 1.9 conversion, ported polished head, large throttle body, cam etc.
had my warm up regulator modified to allow more fuel in but its still not enough.
had it on the rolling road today but its only getting 130bhp
running to lean at 5000rpm and they tell me i need more fuel.
was told to get a mk2 16v warm up regulator and then i could maybe get 140bhp
what have you guys and gals done to fuel your cars for 140+bhp
sorry its a kjet dx engine
any help much needed
cheers

1600 metering head would do the job.

How did they modify your WUR, if its not a 16V item?

i was told there is some kind of screw inside which was spaced out with washers and also some kind of drilling inside was done. had it on the rollers a month ago it did 118/ fitted that today and got 129. so it did something. still not getting enough and am not really that sure exactly what they did to it
1600 metering head sorry for bin daft but thought it would be the same as 1800 metering head    whats the difference
thanks for the help and if you recon it will do the job i will get one
cheers

sorry paul c think i sold you some brackets for the 280mm brake conversion
did you get them fitted and are you happy with them

Still a long way to go before fitting them…

could sell u a vsam pro - that would sort the fuelling out and also allow u to tweak the ignition as well via a pc. i have all software, leads and a few maps as well. :wink:

sorry mate what is a vsam-pro
is it a full injection system never heard of one
would it take long to fit and how much you looking at for it
if it will do the job i am very interested

I'll do my best to explain:
A V-SAM Pro is a unit that was developed to be a method of allowing people running the K-Jet fuel and igntion system (So clearly for early VW's) to adjust the fuelling and ignition systemt to:
A) improve driveability
B) to allow for performance tuning which would require a degree of control over the fuel and igniton curve.

The V-Sam Pro allows the user to adjsut both fuel and ignition via PC based software maps. The std V-SAM only allows adjustment of the ingition, where as the PRO verison has an osiclating valve that you plumb into the WUR side and this then (dependant on which way you connect it) will allow fo reither weakening or rcihening fo the mixtire across the rev range. So for eample you could keep the std fueling up to 400orpm, then dial in a percentage to add adidtional fuel every 500rpm for example.
the igntion side again is based on a map, and can adjust the igntion. This would allow for example a MK2 Disi to be used wiht the MK1 as this has no bobbin weights internally and terefore you can set the advance etc over the rev range via the map to suit the engine characteristics.
You do not need to chaneg the injection system you have as it plugs into the HAll sender in the scuttle for igntion control, and into the fuel side at the metering head for fuel control.

I have the software that allows you to dispaly and adjust the fuel and igntion maps, the lead to connect the PC to the V-Sam Pro unit, and also various maps for various cars including MK1 GTi's, 16v's, and corrado's as it was popular for fettling fuel and ignition without major mods.

The units whenthey were new were around ?400 to buy, this was with no lead, no software, but  I have this as well so you can play wiht the system yourself.

Price wise, sensible offers  I suppose, its on my garage wall, I have never got round to fitting to my car hence the reason for the sale (going down the megasquirt route possibly). Pm me what you woudl pay and we can go from there. I can take some piccies of it for you as well if you like.

Hope this helps explain what it is, any probs or quesions let me know. Oh and a google search will turn up some info on the them for you as well :wink:

PS: sorry for the typos  

it's the modified wur that would concern me. you should be able to get 140 horses worth of fuel from the standard k jet quite happily. modding the wur is so very unesseccary for your purposes.
