Muncie Posted October 16 Author Share Posted October 16 I think biggest gain will be off line it actually scares passengers now when it comes on boost i think its on edge of traction at 6psi which i think ill turn up a bit during day once slicks go on. I've got a 3.45 ratio diff If i buy another car before drag day for parts which would make it pull way harder too. I think it should hang with stock v8s now which isn't bad id say there's $5k invested in parts etc in a $600 car that was destined to be skid hack most likely, Ive got all sentimental about this car now as its the first project I've done all the work on and have it work properly. 5 Quote Link to comment Share on other sites More sharing options...
Muncie Posted October 17 Author Share Posted October 17 1 click equals about 1psi i wound 4 clicks in as a starting point as instructions say start with no more than 1 turn. Immediately hit 12 psi which it took apparently with no issues puffed some black smoke i wound it back 2 clicks and now have 9 psi. It's a bloody rocket! Super fun at 12 pound will save that for the hail Mary run at end of day. Think i better fit a heat shield to protect all this shiny stuff and fit the blow off valve. Sounds different as with more boost through it. 9 Quote Link to comment Share on other sites More sharing options...
shrike Posted October 17 Share Posted October 17 Glad I planted the seed of a boost tap :p black smoke is typically rich right? so might need so leaning out at that boost pressure Don't need a BOV got to get that Dose and turbo flutter Heat shield is a good idea, but id say fuel pump needs to be a priority, how old is the pump in the tank? 1 Quote Link to comment Share on other sites More sharing options...
Muncie Posted October 17 Author Share Posted October 17 Yeah may be original pump I've got an AEM one i bought a while back tanks under 1/4 now so good time to do it. I want to get regulator plumbed in first as the stock regulator won't be able to bypass what this pump puts out could hurt things or pump. It's firmly on list. Stock pump has been doing a great job this far logs show its kept up at 6 psi. Now I've raised rev limit and boost agreed im playing with fire. 1 Quote Link to comment Share on other sites More sharing options...

Plenty of people running stock regs with up rated fuel pumps, pump shouldn't have issues with restrictions hurting it (in my experience happy to be corrected) will just be more pressure less flow if that makes sense and factory reg should bleed it off (might bump fuel pressure up alittle so things will be richer till you swap over) Its what an hour job to swap pumps (and the peace of mind is there) reg shouldn't be much more then an hour if youve got parts? Does the holden run full voltage to the fuel pump or is it variable? could always run lower voltage (to match similar flow rates to the factory pump) to the pump if your worried?

Muncie Posted October 17 Author Share Posted October 17 I'm just jaded after working on PI Triumphs that run at like 90 psi and blow hoses and start fires and draw heaps of amps that cooks up wiring. This just runs a single speed pump the supercharged ones are 2 speed so should be piece of cake drop in deal. On a side note trans is real good but a high stall would be great to help get it up on boost. 1 Quote Link to comment Share on other sites More sharing options...
jakesae101 Posted October 17 Share Posted October 17 im running a DW65A making over 300RWKW the stock one was good for 250 N/A no problems but the DW65A is a drop in to the stock commodore carrier. 1 Quote Link to comment Share on other sites More sharing options...

Muncie Posted October 17 Author Share Posted October 17 I ended up with a lot of rejected AN Stuff from when I worked at Rocket lab basically used a few times not much else wrong they used it for everything we had an AN10 400 series speedflow garden hose....... I've used all that stuff up now I've tried some aliexpress stuff its all good for automotive use haven't tried hose yet might be worth buying that from a legit place. Will do standard hose for now to get me up and running and to figure out what AN Stuff I'll need to buy to replace it all. I want to redo fuel rail so that's got to come off for that. 1 Quote Link to comment Share on other sites More sharing options...
Muncie Posted October 18 Author Share Posted October 18 Realise i don't have any videos of this thing running properly. This is 10psi think this is where I'll call high boost for now I'll turn it back down so it lives. Quote Link to comment Share on other sites More sharing options...

Muncie Posted October 20 Author Share Posted October 20 With the boost tee in the lowest i seem to be able to go is 9psi so might put a mac valve in to bypass it completely so I can get it back to 6psi for normally family cruising and a tiny switch for scaring passengers. Fuel light is on now so next job is the fuel pump and regulator all bit purchased so will knock that out. Engine seems at its best on 10psi pulls clean as no misses or burning smells its surprisingly way quiter too obviously mufflers start working a bit more efficiently and turbo is chopping up more noise with less wastegate venting. 4 Quote Link to comment Share on other sites More sharing options...
Muncie Posted October 26 Author Share Posted October 26 Stop procrastinating and do the bloody fuel pump Dave! That voice in my head got better of me today. I got absolutely covered in shit and have lightened a few kg of dirt and gravel from back of car. 1 Quote Link to comment Share on other sites More sharing options...
Muncie Posted October 26 Author Share Posted October 26 New pump fit the factory pod pretty well wiring was same gauge plug was different soldered the joints and covered using the submersible fuel line that came with the pump as I didn't trust the heat shrink I had. Old fuel filter on pump was utterly rooted pump itself looked fine. Managed to salvage the factory flexible hose and reuse on the new pump. 4 Quote Link to comment Share on other sites More sharing options...
Muncie Posted October 26 Author Share Posted October 26 It's doing some weird shit it felt like it was running out of petrol so I put it 50$ in that stopped it but there is a slight surge at full power that hopefully is the fuel reg playing silly buggers with increased flow of new pump. Hopefully the new regulator cures that or its tank out again to see what's going on. 1 1 Quote Link to comment Share on other sites More sharing options...
Muncie Posted October 26 Author Share Posted October 26 There's enough gear on board to diagnose easier with wideband and the computer setup to tell me what's going on. Have a suspicion new pump may be slightly shorter so just isn't on bottom of tank. No worries I've fixed harder. 1 change is easier to back track on. 1 Quote Link to comment Share on other sites More sharing options...
Muncie Posted October 26 Author Share Posted October 26 Sigh. Found a little plastic gubbin sitting on gound that has obviously fallen out as i was manhandling the pump i remember seeing it at base of pump cradle when it was on bench. Haha for fucks sake I'll be an expert by end of this upgrade. Bonus points if you can tell me what it does. Oh and I'm booked for a wof on Thursday so there's the deadline to be back to running Naturally Aspirated. 1 1 Quote Link to comment Share on other sites More sharing options...
Muncie Posted October 27 Author Share Posted October 27 Don't mean to brag but I can do a fuel tank in 20 minutes HMU. Anyway stick little jet valve in the pump cradle no more fuel starvation...... Was also a little plastic spacer that came with pump to hold screen open. Lesson learned slow the fuck down make sure there's nothing left in box before bolting shit back in. 6 Quote Link to comment Share on other sites More sharing options...
Muncie Posted October 28 Author Share Posted October 28 Now ive got the supposedly 1000hp capable fuel pump in that was basically everything from my hoard of speed parts except the blow off valve that well car goes fine without. Now it's time to roll it all back to 2023 big exhaust and naturally Aspirated spec so tomorrow the turbo is coming off ready for its visit to a wof shop I've been going to in Auckland since the 90s not for an easy pass but so I can get my old man to run for a recheck if need be, hoping it's ready to go only 2000ks since last wof. 2 Quote Link to comment Share on other sites More sharing options...
