Draw through turbocharger setup questions

It is a damn sight more convincing a power upgrade than my $14 supercharger from Honkers, now just $12 plus postage from one supplier. I tried on my tailpipe and up at about 4,000 engine RPM it just spun around like nothing much was really going through it - spin it just as fast with a finger almost, no visible or audible diff between 2000 and 4000 rpm. I think it was made to be similar to a hiclone an soften any turbulence not actually supercharge anything like air pressure .

it will be good for 4-5 psi of boost

TOONGA wrote:Thats correct Gannon it will have to run 2.1:1 on a 2.2 litre engine to give 4-5 psi.

I'm game...

I like your thinking

It might top out pretty quick though. With that said I feel a sherpa modification coming on - it should be small enough to hide without the minister of fun and finance finding out about it!

Yeah it is going to be fun to play with , as well I'm now looking for a cheap water injection kit, to stop the dreaded hot gas detonation syndrome. perhaps I could pioneer an intercooler before the carby. (WTF)

Ive did once hear a story that Mr Brock actually ran a small aircon system in an intercooler to give extremely cold air to the engine. Old mechanics tale?

Hey I could even go back to a holley "ice maker" as that would solve the hot air problem

Research this ... http://autospeed.com.au/cms/title_AutoS ... ticle.html

It is Julian Edgar of Zoom mag founding editor fame. Now autospeed

I started with the capaccino water pump and stopped. Runs on 240V, oh yeah , stopped after I got the inverter. Comprises fogger jets for chok shed, water filter cartridge..... boost light switch for trigger ....

Nearly all the systems available are for MPFI motors, I found this one
http://www.panaceauniversity.org/Simple ... ngwell.pdf

which I'm going to look into, this page as well has a similar set up

http://www.dave-cushman.net/misc/mannject.html

this groovin site has a similar setup as well

http://journeytoforever.org/biofuel_lib ... h/me3.html

All of these systems are the ones I remember people using, when draw through turbos were still being used.

Some of this is common knowledge but...

I've read reports that draw thru superchargers of the Toyota SC12 and 14 have been used for many years with no problems with the teflon (flouride?) coatings coming off. If it does it does no harm to the engine and the SC is still usable for some time. Furthermore they are still relatively inexpensive.

The SC14 better for engines over 1800cc IMO. And especially if weight and size isnt an issue.

Having said that, and proven that the SC12 is a suitable Sc for ea81 engines, eventually I just might buy a Sprintex supercharger. Firstly its made in WA. Second it lighter (4.5 kgms compared to 12) its more compact. Cost for SC alone is around the $1700 mark. Being 600cc it needs to spin a lot faster than the Sc12. Eaton45 is another option. Alloy lobes and no coating I believe???.

My method of thinking however is directed at obtaining 2 more SC12's over time as they become available. Then who cares if they wear out? Seal kits are available, front bearings are sealed bearings and I read they are not replacable (?), rear bearings are repalcable. I think lobes can be recoated. But for the money once you have it set up, like I have now (touch wood...ouch) its an easy process to replace it.

Until I see it I really dont believe that coating comes off so easily. It could all be a furphy. But either way it is all interesting stuff. By the way Toonga...my mother had a Daihatsu Fiori. I chose it for her as it had power steering and aircon and auto option and she sat on the freeways at 120kph no problem. So one of those compact SC's would be ideal. And with slicks...

If TOONGA bought a second littl SC, run twins , one per side ?? No need to stress one out running double speed??

Tweety · Post by **Tweety** » Mon Aug 06, 2012 9:09 pm

one AMR500 for each pot.

Actually steptoe...my milkshake maker doesnt like too much icecream so an aMR500 SC might be the answer....

And we know how Toonga feels about twins

you want to cough up the money for another one

and I will run 2. I can see the dual carby setup, the single belt and double tensioners mmmmmm. I would just have to work out where to put the alternator and the power steering.

We all dream.

At one point I thought about twin SC12's. Then realsied I'd have to redesign the whole mod. I mean couldnt have one dellorto sticking out behind the rear wheel of Tweety.

So thought well maybe set up the single belt so it spins the second charger the other way.

At that point i got a headache.....and went a cooked a stew!

Might be easier for those of us with the twin carb manifold

Well my AMR 500 is on its way from Japan, why Japan? even with courier charges it worked out cheaper that buying it from an Australian seller. the cheapest Aussie seller was $280 for the SC then $40+ for shipping my total cost was 290 dollars.

so now I will have to document the process of building a SC mount and intake system in the PJ spamfest

Look forward to the read.

Good luck Toonga

Will it start with a big heading like this:

SPAM FEST MKII

OR

SPAM FEST NEW DAWN???

Seriously though, I'm looking forward to seeing what trouble you get up to with the build!

just reading this y not go blower blow thro the ex side of turbo and then go blow thro carbie then u get no lag on boost .. all u need is a fuel presser controller for the boost to be a bit higher to feed your carbie then your boost presser for your fuel inlet ...
just a bit of stuff i hear from the old school race boys ...

Post by **TOONGA** » Wed Oct 17, 2012 9:57 am

Too much work Phil, and if I'm going to go nuts and put a turbo on the motor, I may as well go to an EJ20g. Which I can't afford to do and would probably end the brumbys life very quickly

I have in reading foud that because Im only going to have low boost, I can go blow through on a 32/36 or an ADM34. I will probably end up using the 32/36 as it has the nitrophil float. Now all I need is the time, the tools and the place to fabricate the top hat for the carby and the plumbing and mount for the SC.
