Yowzer Posted April 4, 2022 Share Posted April 4, 2022 I've heard that there are summer and winter mixes of fuel, wonder if a) there's truth in that and b) that's why it's now melting your manifold 3 Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted April 4, 2022 Share Posted April 4, 2022 It's certainly true for diesel. (The stuff sold in the deep south is brewed different because cold) Dunno bout guzzoline though? 1 Quote Link to comment Share on other sites More sharing options...
ajg193 Posted April 4, 2022 Share Posted April 4, 2022 This seems like the sort of doohicker you would need for your zero-vacuum engine 1 Quote Link to comment Share on other sites More sharing options...
Roman Posted April 4, 2022 Author Share Posted April 4, 2022 You can get 12v vac pumps for brake boosters for pretty cheap. Like 100 bucks or something. I could use one of the injector holes or just drill a hole in my manifold though I guess Quote Link to comment Share on other sites More sharing options...

Who needs assisted brakes right, can still plumb it into the abs system as well from memory Quote Link to comment Share on other sites More sharing options...
Roman Posted April 4, 2022 Author Share Posted April 4, 2022 Yeah it's not that hard to get a vac signal, the last setup just had a line coming off two of the throttles. It didnt feel quite as good as what you get from a plenum though. For the drags it doesnt matter there's heaps of area to slow down when you're only reaching 100mph or so.

Roman Posted April 5, 2022 Author Share Posted April 5, 2022 Easy to sort anyway, just chopped a bit off a VSV or something from the 4AGE manifold. Wont be super great from just a single runner, but good enough for the moment 7 Quote Link to comment Share on other sites More sharing options...

Popular Post Roman Posted April 8, 2022 Author Popular Post Share Posted April 8, 2022 Last night was wild! I've had this on my mind all week but made sure everything was going to be 100% and didnt forget anything etc. So I leave super early so I could get through scruitineering early, and get some runs early. I stop in at morrinsville on the way to get some food. Start the car back up - and my electric waterpump isnt working! Fucks sake! So I checked over everything and nothing obvious causing the issue. Was pretty disheartened and so I messaged @MopedNZ and @GuyWithAviators to say that I probably wont be able to make it. As they were coming from Tauranga to see it. They insisted that at the least they'd meet me where I was. The previous times the pump has failed, it's been that it just wont hot restart. Because the big starter capacitor cracks or something. So sure enough, once it cooled down enough it started again. This gave me the confidence to take a gamble on that it'll be the same issue, and I'll be able to get there and back home so long as I just let it cool if needed. So, yeah! Second run of the night. 13.49 @ 99.5mph and 2.09 60ft. It was awesome! I experimented with some other launch settings and tyre pressures, my "bad" runs were generally around 13.7. Hard not to be happy with that. I was eliminated on the first racing round by a real quick rotary, but I was real happy to get 4 runs in. This time there were heeeaaaappppsss of people coming over to see what's in the engine bay, or yarns about it. One young lady asked me if I'd sell it to her. Was lots of fun, and a real cool atmosphere at nightspeed again. I rounded out the evening by cruise control smug facing back home in luxury. A++ would drag race an Echo again Big thanks to Andrew and Cullam for coming along and helping / support 29 5 Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted April 8, 2022 Share Posted April 8, 2022 Refresh my memory, Have you done the zhorst yet? Surely you'll crack the Tonne next time? Quote Link to comment Share on other sites More sharing options...
Roman Posted April 9, 2022 Author Share Posted April 9, 2022 Nah its still standard. So go a bit quicker yet maybe. 2 Quote Link to comment Share on other sites More sharing options...
shrike Posted April 9, 2022 Share Posted April 9, 2022 @Romanany option to cool the capacitor? congrats on some good times, keen to see how much you pickup from the exhaust :p Assuming this was with the smaller/lighter rims etc? 1 Quote Link to comment Share on other sites More sharing options...
Roman Posted April 9, 2022 Author Share Posted April 9, 2022 Yeah smaller tyres. Ive been thinking maybe drill a hole in the casing and remote mount the capacitor. So keep it away from vibrations and also make it easier to swap haha. Dunno yet 2 Quote Link to comment Share on other sites More sharing options...
datlow Posted April 9, 2022 Share Posted April 9, 2022 Does it have an option to continue running after shut off to prevent heatsoak? Probably a good feature for post drag run too? Quote Link to comment Share on other sites More sharing options...
Roman Posted April 9, 2022 Author Share Posted April 9, 2022 Ahh not really necessary for an NA motor. I've been watching one of the videos of the launch, and I can see my rear suspension is punishing me a bit. The rear shocks are completely flogged, if I push the car down it bounces about 3 times before coming still. So it's squatting heaps and unloading the front. So maybe some 60ft improvements with some stiffer / solid rear 6 Quote Link to comment Share on other sites More sharing options...
cletus Posted April 9, 2022 Share Posted April 9, 2022 Is that the adjustable suspension that is worn? Quote Link to comment Share on other sites More sharing options...
Roman Posted April 9, 2022 Author Share Posted April 9, 2022 Yeah it is. They're pretty shot. Quote Link to comment Share on other sites More sharing options...
Roman Posted April 9, 2022 Author Share Posted April 9, 2022 Still getting lots of wheel spin off the line, so a lower launch rpm might be beneficial. However it's amazing compared to street tyres how these just hook up and go anyway! 8 1 Quote Link to comment Share on other sites More sharing options...

Rebuild time then are they rebuild able, echo are spring on a perch and not on the actual shock yeah? New shock inserts a go? Quote Link to comment Share on other sites More sharing options...
