hi guys im looking at building a new a15 for my race car, the question is 45mm webers or the efi hardware weber dcoe style throttle bodies and computer.
what i would like to know is has anybody used any thing from these guys and does anybody think that either the webers or fuel injection is better?
thanks kurt
p.s. its gonna be a VERY hot A15

Hi Kurt I went from webbers to EFI quads on my A15. Not a huge diff in power but noticable and much more drivable which is quicker. I use Jenvey's they are better quality and much cheaper. I can get you jenvy quad 45's like mine that bolt staight onto your webber manifold, you get throttle bobies fuel rail linkages for about $1K. Let me no if you want some.

yeah any info would be good dale, and even a website if they have one
thanks

Kurt try this www.compsystems.com.au
I sometimes work for this guy wring up race cars for him. He is a great guy who is willing to help.

Hey Kurt come and say hi at this years AHC at Bathurst I should be there with my SR16 clubbie.
Dale

so you have got all this stuff on your clubman? and what sizes do you have, or if you dont wish to give that information away, what would be a rough guide for an A15 size wise
i think i remember meeting you at the 2006 ahc aswell.

i've heard all good things about efi hardware's gear.
i was in the market for a set of quads for a turbo A15 conversion.
i was planning on going in and seeing the guys at efi hardware and organising a price for a group buy.
Should be able to get 45mm throttles with ram tubes, fuel rail and all linkages for under 1k.
Anyone Interested?

I ran quad 45 Jenveys on my A15 and I have put the same quads on the SR16. I had very large ports on the head which meant I had the idle at about 1000rpm, this was because the air speed was to slow at that point. The engine made 67.7 Kw atw with bad rings on avgas. Also I used a wolf 3d ecu.

i changed from 32/36 weber to the a14 efi and the power down low picced up 10 fold

EFI hardware, highly recommended...
I have a set of quads on my stock SR20.
I have an autronic SMC driving the process.
Apart from the exhaust cam being advance 10 degrees, the engine is a complete stocker from SSS automotive. Its rated at 102 kw at the fly which would be 85kw at the wheels. I got 150hp at the wheels or around 115kw which I reckon equates to 130kw at the fly. Thats 30% increase in HP over a previously EFI engine. I reckon that reason to recommend them.
