Don't attach anything to the +ve of the coil.

Period

Add and extra relay that is triggered off the ignition feed.

You want nothing else sucking what the coil could be if you get my drift...

Lose the 32/36, and get a 350cfm holley. Those webers are junk. (compared to the holley)
TnP is right. I run an ignition feed triggered relay for all my accessories.
HOW DO YOU KNOW IT"S SPARK YOU"RE RUNING OUT OF?
What fuel pump do you have? Blown engines use LOTS of fuel. My electric pump wasn't up to it. The same pump as mine feeds dattodevils worked sidedrafted A15 no worries.

Grunter i hope you are bringing this down on tuesday night for us all to marvel at and for myself to take notes.....


looks awesome mate i can't believe i missed most of this thread...

Bring the spare set of brackets for me to look at too .......

Fuel pump is still the stocker, which is a bit of a worry. I only give it $hit in short bursts at the mo to try and make sure I don't run it dry. I have drilled out the seat to 2.5mm (was 2mm) but that won't be enough to supply 155 and 190 jets, without a reasonable amount of pressure. May be able to go to 3mm, but the needle size is oly about 3.5mm so I am not sure if the needle will seat properly that close to the shoulder.

Got a secondary pump jet which has improved the lean out situation when you boot it, but there is still some pinging.

fuel consumption doesn't seem as bad as I expected- somewhere around 16L/100 during this testing period, so It may even get 10-12 If I nanna drive it. could be expensive when it only drinks 98 RON.

ok ok no need to shout
It is definatley spark because the AFR meter is still reading 11.8. Its quite an effective rev limiter. with thw 4.11 diff, first is over before you know whats going on. second is gone pretty quick as well & you're hammering in 3rd before you get a chance to actually sit back for a bit before you have to grab the next gear.

I reckon the 32/36 is probably fairly well matched to this 5psi setup, but yeah, it is at the end of its range.

When yo usay fuel pump is a stocker do you mean stock A series mechanical pump?

yup stock A15
honestly, I looked in the tech section and it said it would be ok for low boost

possibly time to update the tech section.

Although, since I have rarranged my fuel lines and drilled out the seat, It hasn't leaned out on me.... but I also havn't pushed it too hard. I want to get some professional advice on the whole setup before I go much further with it.

I was just asking - I ran a facet electric pump on my L20 turbo sucking thru a 45mm weber and never ran outta fuel.

I can't really comment on a mech pump - I've only ever had them on stock motors

i was only trying to accentuate my point
I though I had a spartk problem too, untill I put a wideband A/R meter on it and found it was running out of juice.
