VR Senator with LSx454

Mine will be as per factory to get it passed. Then straight to a catch can.

Went through the same thing with the Catch can on mine Gary, came up with a design that works fine now… blew the rear main at one point…

Would like a bit more info if I could Ian.  Mine is combo of the inevitable blow by, and also a lack of vacuum from the induction set up.  Its no big deal but would be a good one to get sorted.  I remember reading the guy with the VC that runs 8’s and is a streeter changes over to a vented tank when he gets to the track.

Yea Cava, I reckon that’s the way, or at least a catch can with a sealed lid for the street that can we swapped to a vented style when you are at the track or giving it a little.  The guys on the US forum even suggested its worth running dual cans, one I think to each bank.

Yeah it’s got to do with and in and out system.

Marzella is gunna make my can for free lol. IOU for giving him a hand to race his car. hahahahha

Not sure yet if I’ll go all to 1 or 2 cans. LS have 3 spots.

I use a -10 line from the left cover to the Catch can, -10 to the Airfilter, the catch can has a -6 to the Sump for drain back.

Between the Can and the Airfilter is a T to a -6 line and a PCV into the intake, between the T and Airfilter is a -10 Non return valve.

The system functions like a normal pcv system when blowby is low, at high rpm if the flow exceeds what the -6 and PCV can pass the one way opens venting into the Airfilter and the fumes being sucked back through the intake to be burnt.

The Catch Can is just a fluid separator with a labyrinth baffle and filled with stainless pot scrubbers for more surface area, the open port on the bottom returns any Raw Oil to the sump, no sign of Oil contamination running it this way for 4+ years.

^fantastic info mate, cheers for that

Very welcome Gary, it’s a variation on a system I ran on my Turbo Supra, it used a thin ring pack and short skirts so breathed heavily under boost, as I said I popped a rear main with the blower motor, 6000 in neutral 0 load… our rear main seals are a face type so don’t cope at all with positive pressure…

The new setup has ran sustained to 7000 a lot of times with no ill effects, not keen on vented catch cans, they stink and make a mess…

What about the valley line?

[Anonymous View build HERE Member since: January 1, 1970 Posts: 0]

FI with my blower doesn’t run one, drivers side cover is the fresh air in through a restrictor in the intake pipe between the TB and Filter.

So I am heading out to this on Saturday night, looks like the weather is going to be pretty nice. Anyone else from SA thinking of going? Nice to catch up with a few of you petrol heads!</span></span>

Well you guys are probably getting a bit bored hearing how much I am enjoying actually driving this, but, you know what, I am really enjoying driving it

Spent a few hours Saturday giving it a good clean, then me with a couple of mates headed down to a local car meet.  Car ran flawlessly.  I gave it a bit of a bootful off the line at one stage and feathered the throttle slightly and  actually managed to get it reasonably hooked up.  Was pretty happy with that, that’s with the Kumhos. Was at the meet for maybe an hour and a half and was a little boring so we headed home.  I know a bit of a secret private (not public road) spot out in the boonies, so a quick detour and a couple of nice 11’s later we were home with a few smiles form the boys.  I think the quote was, “Gary this thing is insane”.  Also got a lot of comments that it is very docile and smooth and normal speeds, which is sort of what I was aiming for right from the get go.

So today is beautiful weather here in SA so we took it for a cruise into Adelaide with my wife and daughter.  probably the first 2 hours of driving I have done in it without hitting the loud pedal.  Just so much fun to drive though.  Cruised past a cop coming back into Gawler and he didn’t even give it a second glance, another thing I was aiming for from the start.  Just enjoying it to the max right now, no longer stressing over every noise, just driving like I intended.

So I reckon this next summer its time to really start having some fun in it.  Some track days at Mallala, maybe Collingrove if I can do an event without a  cage, definitely drag it so see what it has in it as it stands, then maybe some go whoa kinda stuff.  Gotta start planning some of that.  Loving it.

So not much of an update.

Yesterday at lunch time dropped in to see the tuner to say g’day, and let him know how its going.  We spoke about this next summer coming, me really using a bit, doing some racing etc.  So his thoughts were just drive and and enjoy it like it is over winter when I can.  He admitted he has set it up a little on the rich side for safety.  So after winter will get it back to him for a day, might even start planning a flex sensor set up so I can set it up on E85 to gain those few extra ponies but not lose the ability to cruise it most of the time on 98 (I think that’s how it works isn’t it).

Mind you he he is an ex drag racer and just smiled and said he thought getting it to hook up will be the challenge, and said to me don’t bother about more power right now.  He is probably right, be good just to get a baseline on where its sitting now.

So took it for another hour long cruise around Gawler today.  No issues at all, still lots of fun, almost mundane driving it around now

Race it as is. You will go faster getting the setup right then you would chasing more power atm.

 

Ideally you you would be best to put some standard shocks and fe2 in the rear as supposed to your coil overs and then go in for a wheel alignment.

Marzella just did a nice setup on his for Holden Nats. He had some great results.

Thanks for that Cav, makes sense.  I guess also I will at least know where its at.

I never get sick of reading about this thing lol!!

^thanks very much mate, well I never tire of sharing it with people

So “Fuel Flex Sensor” a few questions of those in the know;

1.  What exactly is it, am I right its a gizmo I splice into the fuel feed line that senses the ethanol content of the fuel and tells the ECU?

2.  If thats the case, given I am running 5/8″ feed lines, so would I need to buy a sensor with same bore, i.e. are there different sizes or it doesn’t it matter?

3.  I am running a VY LS ECU.  Will this work with the sensor?

4.  Is it as simple as; say I have been running on 98 for a while on the street.  I stick it up on the hoist, drain the 98, fill with E85 and the ECU does what it needs too to cope with the E85 and off i head down the qtr?

5.  Does it need like 2 separate tunes, one for 98, one for E85, or does it just modify some basic parameters like timing in a single tune?

What else do i need to know?

1: Yes correct

2: You can run it in the return, you won’t find a -10 sensor

3: is an LS1B ECM?

4: If it’s set up as full flex fuel you can run any mix and the car will run at it’s optimum

5: No the idea of flex fuel is you have an 98 tune and an e-85 tune and the ecu will then adjust to suit whatever blend of fuel is currently in the car.

Thanks Ian, seems almost too good to be true, is there a downside to running one, otherwise it has to be the go I think for a car like mine. I want to be able to run 98 most of the time but E85 occasionally.  Actually i would prefere to run E85 all the time but its availability near me is pretty ordinary.

Not sure how do I tell if I have an LS1B ECU, is it written on it?

[Anonymous View build HERE Member since: January 1, 1970 Posts: 0]

Being a VY PCM it “should” be the B version, it has more memory and is “faster” not sure on the external differences but yeah there should be a number on it..

Good article on the PCM’s

Tbh you prob won’t see any notable gains with e85 with ur engine.

 

Are your fuel hoses e85 compliant?

 

It it will defiantly need a tune. Not just plug and play as it has no base e85 tune.
