Nebuchernezzer Posted July 16, 2006 Report Posted July 16, 2006 Well if the reg has fuel return then that is that sorted, i'd rather use an external pump like a VL one mounted under the body somewhere.
Taz_Rx Posted July 17, 2006 Report Posted July 17, 2006 I'm going to try the 3k block, 4k head thing one day, main thing on these motors is right turbo, need a small one. simon, your running the CT12 right?, what about a CT20? you could try one of them seeing as yours runs outta puff. yeah its a ct12, thought about the ct20, but itas just a matter of finding one that will fit in with my tight arse rolla budget!! :jamie: might end up with a t2 or some thing one day.
ArJay Posted July 18, 2006 Report Posted July 18, 2006 (edited) Hey Guys.. First up awesome thread. Heaps of info in there...keep up the great work! Thinking of running a turb setup on an AE71 that a mate and I are building for sprints. Quick carbie turb noob question for you. Noticed that on your carbie setup Taz_Rx you used a pressure box but Boost+k didn't. Was this to do with the SU carb he's using? Are they more suited/sealed for turb applications.....? Cheers mate.

Hows that cam settling in mate,I'm sure if you re-tune youll find it will work nicely.
Falken_KE30 Posted July 18, 2006 Report Posted July 18, 2006 (edited) last i heard it was a bit rough, and made the clutch slip, or was that cause you can't do a skidd.... :jamie: Edited July 18, 2006 by Falken_KE30
Taz_Rx Posted July 18, 2006 Report Posted July 18, 2006 so you wanna skid comp for slips dan!!?? :P :jamie: cams good now that I've got used to it!! did you get the PM I sent about running more boost!? lifters are on the way btw. :lol: ArJay- Sometimes, depending on the carby if you just put the boosted air into the inlet of the carby like boost+k's you can get boost leaks through the gaskets etc of the carby. the box is something I originally thought of to avoid this problem. basically there is equal pressure on the outside and inside of the carby in the box so theres no point in it leaking through the gaskets!! short answer- I'm lazy!! :cool:
Nebuchernezzer Posted July 18, 2006 Report Posted July 18, 2006 Lazyness is next to godliness IMHO :jamie:
Falken_KE30 Posted July 18, 2006 Report Posted July 18, 2006 hahaha, u crack me up simon!!... aslong as i can have a tonne oil to start the skidd....:jamie: w00t, might be picking up a 4ke injection setup, well some off it, but will hopefully go together soon enough!!

So am I correct in saying that Boost+k's carby must be a full sealed unit? Would most SU carbs come sealed like that or do you need to rebuild them to suit? Cheers again R:)
Taz_Rx Posted July 19, 2006 Report Posted July 19, 2006 (edited) I know stuff all about SU's so I'll let someone else answer that one!! boost+K?? reckon they'd be sealed pretty well though. might just be a case of adding some strategically place goop here and there to make sure!!

Would most SU carbs come sealed like that or do you need to rebuild them to suit? his SU carb is from a MG metro turbo. they are not that commonplace. have a look at this link to modify a HIF SU for blowthru use.
Boost+k Posted July 20, 2006 Report Posted July 20, 2006 yea hes right mines off a factory carbie turbo montego so i didn't have to worry about sealing it off but i still get minor leaks from the float bowl unless i use a genuine gasket but then the genuine gasket leaks as soon as i put av gas in it :hammer: i have mine hooked up way different to that diagram above.... next time i put my turbo on i'll try hooking all the pipes up like that but personally i think its wrong.
ArJay Posted July 20, 2006 Report Posted July 20, 2006 Cheers guys... great info once again. So would it be fair to say that using a pressure box would be the fail safe way to go then? Sounds like a fair bit of buggering around involved in converting the standard SU over.... R:)
Taz_Rx Posted July 20, 2006 Report Posted July 20, 2006 yes and no!! the box might be an "easy way out" but in practice it has a few challenges!! few things you would want to keep in mind if you were to go down that path are: depth of the lower half of the box! - you want something pretty shallow so you can get to the bolts/nuts that hold down the carby (depends on what carby you use) and also get your hands in there to tune it. but you also want it to be high enough the be able to get a trottle cable and fuel line through the bottom part, cause you don't want to have to take these off to get to the carby for tuning etc every time you take off the lid. the seal between the upper and lower parts - you need something that is going to hold the amount of boost you are intending to run. this was my biggest problem when I first got it running and took a while to sort. what I ended up doing is putting threaded rods the same hight as my box that bolt to the lower half and then have wing nuts on the top, this way you can screw it down nice and hard and so far mine has held up to 15psi!!
