Turbocharged...
hey guys,
is there anyone know any article or site contains a detailed turbo installation(beside vwtrends) for the beetle, cuz i'm stuck in the middle now and have problems above my knowledge,,,... my fuel pump, i will remover it from it's location to fit the oil support to the turbo, so i will go for a electrical one, what i should consider when i buy one, and how can i adjust it to feed the system propably,... and i have 2 options in the turbo fiting, the draw-through and the blow-through, witch one is better, and what is the adv. and disadv. of both... plz guy support me with infos or links, i know my question is alot but ur experts and u really know what ur talking about... thank's... |

Have a good hunt around the shoptalkforums, here http://www.shoptalkforums.com/viewfo...8291899422a8e5
Probably loads of answers to your questions. Are you thinking carby turbo or EFI? And also lots of interesting info here http://lowbugget.com/1600t.html and check out http://www.dune-buggy.com/turbo/enginebasics.htm Good luck

but i have a very important question, i think we should all know before adding a forced induction system to our weak aluminium engine, what is our boost limit that the engine could handle, i guess not much, my engine's compression ratio for example is 7.30:1 (1300cc, F) when in good condition, so how much the safe ration i could add to it with the turbo???????? deos anybody know???????? thank's man for replying... |

If you plan on doing a carburated turbo motor go for the blow through. It might cost a bit more (modify the carbs), but i believe its a lot safer and more effective, since you dont have the air/fuel mixture going into the turbo which gets extremely hot...
Personally for my next motor im planning on big cc's and a turbo with efi... Chris

keep it simple and do a drawthough. if u want the benefits of blow through, go all the way and do EFI.

carb modifications are : different gaskets and different o-rings at the butterfly shafts in order to handle the pressure. appart from that you should get some bigger jets for your carbs to match the required fuel levels when under boost (otherwise your engine will run lean and start detonating...).
if i remeber correctly the carb turbo kit is available from cb performance. Also look for a small turbo (small>nil lag thus better drivability for a daily driver) with an integrated wastegate (most OEM applications> easier to find and cheaper) and a seperate blow-off valve (that will protect your carbs and your engine from excecive boost pressures) Chris

really thank's guys for this info,...
i found that i have to buy an electric fuel pump with a regulator, and fit the oil supply hose in the place of the pump, but my question is what pressure should i set the regulator to work with me... thank's... |

Interesting question and actually i dont have a clue...
One way to find out is to calulate how much fuel your jets can flow, along with the fuel requirement under boost and then find out the needed fuel pressure... If i remeber correctly weber 40 work at 2.5-3.0 bar in NA mode, so i wouldnt be impressed if your engine will require something like 6-7 bar (do not take it for granted plz and make your calcs or ask someone that has done it before or sells kits).

Cb Performance has a few pressure regulators... http://www.cbperformance.com
also check Holley http://www.holley.com/data/Catalogs/Fuel%20Pumps.pdf Its a very interesting article along with the fuel pump catalog Chris

So your turboing a 1300? You'll want forged pistons, and by the way it's a magnesium alloy case which is even weaker then a aluminum case. You won't be able to get too much boost out of stock motor unless you go through it. After everything is said and done you would be better off with a built NA type 1 motor.

but now my idea is to build a "street car" with minor modifications producing the best power it could safely gives, i took it as a chalenge ;-)... thank's... |

Fabbing a turbo setup will cost more then buying a good used 1600. I have built a couple of 1641 screamers, but there is no replacement for displacement.
