yoeddynz Posted April 5, 2021 Share Posted April 5, 2021 I second mr pogs comment. I hope your brother @Unclejake is going to keep the cab as is and just cruise around looking the boss. Damn I'd love to see a build thread on that! 1 1 Quote Link to comment Share on other sites More sharing options...
Popular Post ThePog Posted April 11, 2021 Author Popular Post Share Posted April 11, 2021 A minor amount fucking around this weekend. I thought I had better sort the cold idle issue, I had fudged a little cam lever type arrangement on the throttle pedal that lifted the revs a bit when cold, but it was hard to get to from the seat and wasn't really adjustable enough. This has been fine over summer but it's getting chillier in the mornings here. I eventually settled on the idea of using a central locking motor to give an adjustable amount of rev lift; You can see it up in that mess. It hits the screw, pushes the pedal a bit but doesn't get in the way of the pedal movement. There is a switch on the dash that activates it. Cool cool. After a discussion with some boys who know more than me, namely @mjrstar and @drftnmaz , I have removed the line to the turbo boost actuator and am FREE BOOSTING MOTHER FUCKER FUKIN HARDCORE LOLXZZZ. It seems that the fuel setting on the new pump wasn't allowing enough boosts to develop, as I was only seeing 7 or 8psi. I bypassed the actuator and wound the fuel up a 1/4 turn. This now gives me a very lively feeling 10psi with potentially more when I become jaded with the level of neck snapping acceleration I am getting. Also I have pretty much decided to fit an auxiliary radiator down in front. Things work ok but I am uncomfortable relying just on the fan to keep temperatures in check. I might fit a trundles modified thermostat first just to see what effect this has, these are supposedly the tits. Laters. 14 Quote Link to comment Share on other sites More sharing options...

Yowzer Posted April 11, 2021 Share Posted April 11, 2021 I really think you're worrying about the cooling system way too much. Keep it simple and it'll keep working. Great news on the increased boosts though! Quote Link to comment Share on other sites More sharing options...

Unclejake Posted April 11, 2021 Share Posted April 11, 2021 I tend to agree that a well placed radiator is a preferable option to forced electric airflow. I should be back on Chatham 20th April. My Dyna has a factory air conditioning radiator mounted under the cab. It lies almost horizontal. I'll try to get a photo so you can see if that position could work for you. I had good results with a Davies Craig electric waterpump on my race car. I also used Redline WaterWeta in the coolant. Quote Link to comment Share on other sites More sharing options...

I'd be interested to see this although I have a spot that I can get decent airflow to without much effort. I had a quick look at standard rads and I reckon an S1 MR2 will fit the space pretty well. I will investigate further. Quote Link to comment Share on other sites More sharing options...
Raizer Posted April 12, 2021 Share Posted April 12, 2021 Hiace Super Customs also have radiators flat under the front, they might be worth looking at too? Quote Link to comment Share on other sites More sharing options...

I had a proper look last night, I could probably get that to work. Ideally 500mm wide and 300mm tall with 38mm outlets, might be hard to find..... 1 Quote Link to comment Share on other sites More sharing options...
ThePog Posted April 13, 2021 Author Share Posted April 13, 2021 Ha I clamped the wastegate shut last night and just now took it for a hoon, it's hitting 15psi at 3.5k but that's as far as the needle goes, it goes like the clappers now. Also I reckon the Hiace HPR auxiliary radiator is probably the one, it will definitely fit and the outlets will work. Maybe a bit smaller than I want but readily available... I was also thinking I could maybe have a hack at that custom rad that now sits in my shed, cut it down to suit. Ill check it out tonight. 4 Quote Link to comment Share on other sites More sharing options...

Please don't blow it up Yea I have an egt gauge, the most I saw just now was 600deg pre turbo. I also just installed a gauge that goes up to 1.5bar if it gets higher than that I will back off the fuel... 2 Quote Link to comment Share on other sites More sharing options...
Yowzer Posted April 13, 2021 Share Posted April 13, 2021 600° is pretty safe. Ya can push 700 if you really wanna but for a big lump like that 600-650 is mint 2 Quote Link to comment Share on other sites More sharing options...

Popular Post ThePog Posted April 19, 2021 Author Popular Post Share Posted April 19, 2021 Got a mention on the deboss YT channel which resulted in 5 more subscribers to my youtube channel last night, that's 5 more people primed to be disappointed with the lack of proper content, yay. The mention is mostly surprise that something with such a low level internet presence and no direct link to the vids did so well ha. I am pretty shit at social media, I'm just too old to care. Also I'm in the midst of various chunky changes to the truck, should be sorted by the weekend, I'll post some pics then. Also I made so much boost the intercooler piping blew off, that was good fun. Turns out there is really quite a lot of extra fuel that doesn't get burnt without the extra air from the turbo as evidenced by the epic clouds of black when the throttle came even a little bit off idle. I improved the bit that fell off and wound the fuel back to factory. It's still making 1 bar but isn't as hectic. 13 Quote Link to comment Share on other sites More sharing options...
Popular Post ThePog Posted April 26, 2021 Author Popular Post Share Posted April 26, 2021 Right o, the latest round of fuckery. As discussed, I decided that a second rad was going in, regardless of you fuckers who said not to worry. Basically the thing bouncing off the electric fan just by hitting 100kmh for 2 mins or after a hard pull was not giving me the lovelies. After a measure up I scoured the internet radiator catalogs for a suitable donor. Unsurprisingly a Hiace van rad was pretty much bang on if maybe a little tall. I ordered one from my rad man and when it arrived presented it up. A minor forward tilt had it sitting in a good place. The top inlet pipe was a stupid angled thing so I took it back to rad man to change it for a straight inlet. I made some bottom mounts that hooked in to existing chassis holes, then fudged up a top mount. I had to grind off some unnecessary brackets and such but that was no drama. Then I spent quite a while rejigging the stainless pipework to point in the general direction of the rad pipes. I dragged the old fan and viscous clutch setup out of the container, however the 450mm safari fan was going to be pretty tight in there and probably going to hit the engine cover. Some google-fu resulted in the purchase of a TD27 fan, as it had the same mounting but only 420mm diameter, perfect. I then somehow spent nearly a week of evenings fucking around creating a shroud that would miss everything but still do ducty good things.. I have no idea what it took so long, but it did get remade 3 or 4 times. It's a bit dodgy, ie made out of some old flashings that were the only really thin steel I had lying around, but it appears to duct adequately. So today I finally filled and bled the cooling system and took it for a spin, and holy shit what a huge difference! It basically gets to 1/3 of the way up the gauge and stays there absolutely rock solid. This is where it sat when doodling around town previously. I did a long run at 100kmh, then went up a steep hill that had always made the big fan come on and it didn't move the gauge at all. Super happy with that.... It also appears the thermostat now has a temperature range it can work with, as the wee fan and aux pump cycle on and off which tells me the thermostat is choosing to open and close rather than stay open all the time in an attempt not to blow the engine up. So all in all that was a worthwhile exercise. 26 Quote Link to comment Share on other sites More sharing options...
Popular Post ThePog Posted April 26, 2021 Author Popular Post Share Posted April 26, 2021 And this as well, which I filmed halfway through the process. This was cos i am now under serious pressure to provide content to my now 189 youtube subscribers, fuck you for suggesting I enter that competition. 10 7 Quote Link to comment Share on other sites More sharing options...
Mof Posted April 26, 2021 Share Posted April 26, 2021 I can't see the mounts in the pics very well, is the rad going to handle being attached to the chassis and the cab ok? Quote Link to comment Share on other sites More sharing options...

The bottom ones are on soft mounts, and the top one is slightly more rigid but still rubber isolated.... 1 Quote Link to comment Share on other sites More sharing options...
