How much preload was on the stock actuator when you refitted it? Unless it was far to much it shouldnt have had an issue. The details on the port job seem ok for your boost level. Just to give you an idea. I run a 4"dump with into twin 3" exhaust with a larger PTE6466 still internally gated (granted the PTE rear housing is designed for this turbo and the wategate works nicely. The car made 499rwkw with no boost creep/overboost. On actuator pressure only the car runs 17-14psi. Do you have a means to log this vehicle at all. Does atleast one of you have an Xcal and a laptop, the SCT datalogging software is free and you use an Xcal as the interface. Need to log this vehicle and find out if it is actually boost cut that you are getting. Failing that, its back to your tuner unless you can get the tune file to us to have a look at and see what could be the issue.

^that is actually stated in the HP ford tuning manual!! I havent had an issue yet?

You mentioned you have a 7lb actuator, did you test? Need to know how much preload is on the gate flapper and and at what psi the actuator os fully open. Who did the port job? Wouldnt be the first time we've seen sh*t port jobs just have the hole enlarged with a bigger flapper with know thought put into the flow characteristics of the wastegate path

Bypassed how? Plumbing the boost signal directly to the actuator? Or turning it off in the tune? If it is a professional shop using HP tuners to tune a falcon I'm assuming he doesnt do many?

^Does that equal 6?..... or is that in the "not so helpful pile?" HP are carrying out a major software update as we speak, I'm told it will be one big step towards sorting the scanner out.

Tune related. Get your tuner to change the ramp rate on the dyno to replicate what it sees on the street and tune it properly or take him for a drive on the street and get him to touch it up, fairly common for boost levels to overshoot on the street, when its tunes in open loop boost control.

I've been using the Lucas Brand of ethanol conditioner/stabilizer for nearly 2 years now, been running E85 constantly since, still with stock steel and rubber lines from the tank to the surge. (apart from the line from intank pump to sender bulkhead, as I changed that when I did the pump). No issue at all yet

Last time I priced up gears, for the M86 the shop I spoke to said you couldnt buy 3.23. Options were 3.08 or 3.46 which would be too short imo, I was leaning towards the 3.08 and a first gear delete also now I have access to TCM tune.

I think Kent Battle went a 9.5 the other day at, cant remember mph though

Thank-you, appreciate it.

www.youtube.com/watch?v=dgZupPhrMss Mine isn't the best example for what it is capable of (gotta get the boost curve flat, currently 25 falling to 20psi) but this is my best run so far (bolt on 6466) hit the fuel cut limiter on the 1st-2nd upshift :( With a better 60ft and some more dyno time I'm confident it will run a 9. That is the goal anyway.

I only have the Snow old stage 2 kit, the flash new ones (aswell as the AEM) have a low and high flow tolerance to interpret both kinds of failures (restriction and leakage) and can be used to trigger a multiple of outputs, on aftermarket and Dizzy type situations you can change use it to retard the timing. But On our cars if you wanted a failsafe you can run a solenoid on the small ID boost reference line that goes to the blow off valve. If either of these conditions occur you can have controller switch the solenoid state and remove the pressure reference to the opposite side of the spring in the BOV, this would increase the pressure differential and create a major boost leak and drop the boost pressure right down and hopefully save the engine. I believe they have all sorts of bells and whisles etc on the controller to raise the alarm.

I just bought lifters for mine for a rainy day, the best place I found was Tony at TBRE, it appears he has found the supplier that atomic use as he states they come in the same packaging. What he doesn't know 100% yet is if the ones atomic use come as is and they just on sell them and they are built as such. or if Atomic actually purchase them then modify in house. I haven't been able to see any difference yet. need to pull them apart and take some measurements

^My thoughts exactly. I wasn't 100% sure on exactly flow data but was confident the twin walbro's flow more fuel than the 044's, but it doesn't matter. We need to start going through the process to get it sorted. Check the base fuel pressure with the vac line off firstly and we can go from there.

When you say you have 70psi at idle is that with the vac line attached to the reg or is that base fuel pressure? How are your twin pumps wired, are they run sequentially off a hobbs switch or are they full time? Ive got stock return size with a holley 12-1800 and fpr1200. But I stage the second pump off a hobbs. Set the base fuel pressure with the vac line off the reg at 4 bar/58.5psi and see if you have enough adjustment in the reg. If you dont then you are limited by the size of the return most likely, staging might help but it is really only trying to cover up for lack of return size.

Flashed the ZF last night, 20sec flash times. Impressive

I know it helps here mate, It gets pretty humid here In Gladstone too. I would go for it

Actually which one of you is running the AEM setup? I think I recal dave talking about on the phone the other day. did you get it sorted? sounded like a good unit. alot flasher than my snow stage 2

I think what puts some tuners off it is it opens up potentially. If you are tuning the car for more power using the Watermeth, it means less fuel and more timing usually. If you have a customer who doesnt take care of the car then you can imagine what will happen if the watermeth fails.... Seen this first hand actually on my cousins car. He had his water meth on a switch( Which I dont recommend) So basically we were travelling to powercruise. Had the big tune in on the xcal, forgot to turn water meth on, melted a piston. That is why I set mine up with a wiring harness, so if you want to disconnect it, physically have to get out of the car and do so and vice versa, so when I was using the xcal It would trigger my brain to make sure I change the tune in the xcal. The Sparkmax is the JMS/Herrod setup, is a voltage booster and increases output to the coils, very nice unit, bolts in actually, nice little bracket, takes 15mins to install. According to Herrod my issue is tune related and I have to disable Repetitive spark, unfortunately with HP tuners I dont have access to this table so I'm waiting for support to add it for me. Once that is done I will go and finish the tune. Im led to believe that with that sparkmax and leaning the fuel off to .83-.85 there is another 30rwkw left in the setup, maybe more if I can get the boost to stay flat. At the moment using the eboost it makes 25psi and falls to 20. I was planning on running an RPM correction to the Eboost to keep the boost at 25psi (or as close as possible) but it used the signal coming into the sparkmax. Once I disconnected it to troublshoot the missfire I could no longer run the RPM based correction.

I had some more dyno time over the weekend, had some hiccups with my spark booster and was loading the car too hard according to some, but when I hooked up the water meth 375ml jet the car picked up over 35rwhp no other tuning. I also zero'd out all of the lambda multipliers and IAT multipliers for spark and even double checked my logs I took on the dyno. The car added no additional timing. Yes these results would have exaggerated because I was loading the car really hard on the runs (10km/sec) but there were no additional changes. I didn't lean it off or anything. Just cooler IATs on the back to back runs. There was no time cooling down between hooking the meth up either as it is only one plug in the engine bay and its on. But it went 499rwkw and pretty happy. Once I get the sparkmax and my tune sorted will do some more testing and keep you posted. Dave is actually helping me get the Sparkmax sorted. But I think with a larger plug gap there will be decent gains, that aswell as leaning it off a heap as it is still quite rich. .80 lambda

I still run the water meth with E85 mate, just a small Jet for cooling. Could keep going up in jet size until it starts to quench but haven't really bothered.

Sweet, When I was on pump fuel I just used to carry an addition small 5L jerry can to take to the track or powercruise etc, and had two separate tunes for the water/meth. But now I just use it to keep IAT's down with the E85 so it doesnt matter if I run out. I think it did help save my new motor though. At the track I ran out of intank pump and the time and it went lean on the gauge (leaner than where it sits normally with the meth on) It was showing .9 on the AFR gauge when I backed off as I felt the hesitation in the deep end. I had tuned it at .80- .82 on E85 but it would site about .72- .76 with the water meth without hurting power. Not sure how much punishment the built motor would have taken but I'm glad I had it on. You wont have any dramas with Dave mate, he is a legend. He tuned my car the first time before I had bought software. He was the one who got me onto the water meth

Holy Fu$k that is a yooge tank. Mine is only the little one just under 5 litres and it lasts for ages at the drags. The pumps in the snow kit I have is identical, and the controller operates similar also. It has a boost reference, and two dials. the First one is the boost level trigger and starts the pump at about 10% duty, then the second dial is max boost (controller only goes to 19psi) but will be running 25psi shortly. and the Controller adds duty to the pump proportionally. I love it man. Keeps the motor clean inside too. Stops alot of the carbon puss building up. Water meth and a catch can would keep those shiny built engines looking mint. It did keep my stock motor alive when I started learning to tune. Pulled it down when I put my built engine in and looked perfect.

I've put one of those bolt on 6466's on mine. So far it went a 10.8@131 on 20psi (boost was dropping off, still had twin cats) and a good ol zf limiter bash from 1st-2nd Second run was stalling it higher and broke the hardy spicer cv on the built shaft. I've cut the cats out today so will retune it shortly and see what it does with 25+psi. My only concern is the headlift that all the tuners talk about so will see what mine does, will lean it off if I have to. If I had workshop doing mine it would be done already, but doing my own after hours takes time lol
