Cheers, Some more braided lines and fitting to sort out for the booster vacuum and coolant bypass and it’ll be ready to bolt on.

Just thinking out loud, is it possible to remove the linkage between the two shafts and just operate on one pair of butterflies in the current set up then go the full 1375cfm once you need it later on? Might be dumb ass, just thinking your would more or less double the air speed through the two throttles which might be happier at the lower power needs?

 

That’s fairly much exactly what I’m going to do.

I can alter the secondary linkage to limit how far they open.  I’ll use the MAP sensor to work out the optimum by how much of a vacuum it pulls at WOT through the rev range.

Yeah,  I’m quiet happy I went with the billet alloy one instead of the cast alloy jobbie from Edelbrock.

This Aeroflow one is actually rated at 1375cfm even though it has the same venturi size as the Edelbrock @ 1.75″ but this one has much better tapered runners into the butterflies as well as the butterfly shafts have been machined down etc which may account for the extra rated flow?  It really is a bit big for this engine but should be ideal for future plans.

So the last major piece of the puzzle has finally arrived

Now that I have that I can dummy fit it to the engine and start sorting out the wiring looms etc.

Do you know the injector part number?

It is very possible that those injectors flow more than standard + a higher fuel rail pressure will mean it’s getting to much fuel.

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

Right, my bad.

Standard pressure is 43psi with no manifold reference (at idle with the manifold reference hose fitted you will see less fuel pressure) try that and see how it goes.

 

BTW, what injectors are you using?

What is the actual pressure when the engine is running?

I’d suggest that the stock FPR with A1000 pump might be on the small side possibly causing excessive fuel pressures.

Do you have a non-return valve in the supply side after the pump but before the rail?  If not that would explain why the pressure drops after priming.

Nahh, my next ignition upgrade will be a coil per cylinder setup

Yea I know, sometimes I start to think, man I wish I had just gone a regular injection set up like a Fast or whatever, then I stop and look at it all nice and purdy and go “yea nah”, reckon I will try and make this work

 

I know what you mean, I started out doing a simple manifold swap, now I’m fitting bloody braided hoses everywhere.  Where does it stop?

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

LOL, ^^^^ life is a little harder when you don’t have a common plenum as a nice source of vacuum for a regular PCV system.  Such hardships you have to deal with…..

Who knows but the reliability of the new mosfet chip has to be an improvement even before you consider the improved power/current switching ability of said chip.

VN-VT all use the same module.  As far as I know they only sell on ebay.

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

Yep, Check out the link above.  Have a chat with the guy, he knows his stuff

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

Good modules those, much better than the OEM version 

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

Yeah, I would have had to change it all out one day to suit future plans so I decided to bite the bullet and get it all done now.

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

The guy I’m dealing with suggested bringing in the manifold so we could piece it all out on the bench.  I guess that’s not really possible in your situation though 

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

I’m trying not to get ahead of myself and end up with a whole lot of fittings I don’t need or can’t use.  Seems my local supplier has a good stock of fittings so most stuff is available on my doorstep the next day

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

Ordered more Hose and fittings today, all in black (off course) so I should have everything now to complete the fuel rail/FRP install bar fittings to hook up to the hard lines which I’ll get once it’s all in the car and I can figure out the angles to make it all line up.

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

Damn shame I don’t have a T56 cause I’d snap this up.  Had a billet shifter on my old T5 and it was great bit of gear.

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

It may pay to add how much you want and what models these brakes will fit

[ImmortalityParticipant 97 HSV Senator 185i 02 VX L67 Calais View build HERE Member since: August 31, 2015 Posts: 535]

So a slight change in plans, I have gone with the Aeroflow fuel rails as they have a lower/slimmer overall profile for a slightly cleaner/tidier look and it will also make future plans a little easier.  The brackets supplied with the rails are to fit the factory manifold, I’ll end up making some more that will bolt the rails directly to the manifold to make it look a little tidier again.

Just need to order some more hose and fittings to mount the FPR (Turbosmart 800) and complete that part of the swap.
