I have a porsche 928 and I was wondering if I could add an electric supercharger?

Question

Would I have to recalibrate the whole fule system in order to keep up with the extra boost?

Answer 1

Well, the good news is there isn't anything extra you'd need to do for the fuel system to keep up with an electric supercharger! The bad news is that electric superchargers are not very cost effective ways to add an obstruction to your intake system. You can get much the same benefit for less by simply sticking a wad of wet toilet paper over your air filter (not to sound overly commerical, but I'd be willing to supply you with an extra large wad of wet toilet paper for the low price of $150!).

If you want to add power, a real supercharger could be an option, and some have used them with some success as long as you are keeping to a relatively low boost overall. However, at the end of the day, when you look at the costs, you'd probably be better off looking at a different car that has the amount of power you want. Taking a 928 and adding more power will be expensive, and then more expensive when you realize that the suspension and brakes now need to be upgraded to handle the power increase.

Answer 2

4.5L, 4.7L,5.0L,5.4L V8? Is it universal? If so then you would have to probably relocate the battery to the trunk and swap out the air filter for more space to fit the universal supercharger. An electric supercharger will only give you about 30hp. A 12v battery would power it so you would not get a lot of boost. One thing they don't say in about the electric supercharger kits is the large amount of amps is pulls. When it kicked in it would put a large strain on the alternator. Thus severely shortening the life of the alternator; even if you used a high amp alternator it would still be a large strain.
Superchargers have a constant drag on the motor since it has a belt or chain but it does not have any lag. Turbos would have a higher boost level but they have turbo lag which is when it takes time for it to spool up, it relies on forced induction. Yes you would probably need to remap the ecu although electric superchargers dont give you too much power.

Answer 3

Depending on the system you buy, you will need to remap the fuel system. Most units are trash, probably can't supply the volume of air your car needs, and if it can, you might only get 1 or 2 PSI of boost. Thats only 6.8 to 13 percent, or 13 to 30 extra HP. I heard of a kit that uses seperate batteries to power 18HP worth of electric motors and is capable of about 20PSI boost, but only will work for 15 seconds before needing to charge. Cool part of that system is flipping a switch turns off the charging system, so you get no parasitic loss when under boost (for 15 seconds), then the batteries recharge in about 8 minutes. I think its called an ESC-400.

Electric superchargers are mostly worthless; it takes TONS of horsepower to turn a regular supercharger, what makes anyone think that an electric motor can do the same thing!
Your best off with a custom made system using one of them centrifugal superchargers and an intercooler, bigger fuel pump, injectors...

Answer 4

dude a 928 is old...you had better get all the internals redone first....a supercharger is a ton of stress on the components of an old engine like that...even at moderate boosting...

and yes a supercharger is a very elaborate system the whole fuel system will need tuning...

Answer 5

an electric supercharger doesnt add any boost. They dont do anything. A normal supercharger can use like 15 hp to spool. Thats like 10,000 watts. A 10 watt fan isnt going to do anything. itll just get in the way and restrict airflow.

Answer 6

In the last couple years, there have been a couple folks marketing superchargers for the 928. 928 Motor Sports has a good reputation, check them out.

Answer 7

It won't artwork. i think you will use some form of ducted fan motor and hook up a 12 volt battery %. of a few form? those vehicles do pass lots of air. there is not any doubt approximately that... the subject is they do no longer compress the air in any respect. with a view to get extra ability you prefer extra air in the comparable unit of area. With extra air in the comparable area, you could burn extra gasoline, generate extra tension from the combustion technique and subsequently make extra ability. to learn from this technique, you could compress the air and tension it into the cylinder under pressure. Your electric fan won't be in a position to try this. It purely strikes the air on the instant. you prefer some form of compressor. in keeping with risk you could discover an old speedier, it might could be very very small to artwork with your engine. As became stated, to your utility, Nitrous is the main suitable and least complicated and beneficial maximum inexpensive option. purely remember which you will grant better gasoline with the nitrous. you're able to try this with a 2nd gasoline tank and in keeping with risk a 2nd gasoline jet. an extra handy way is to truthfully use a small propane tank as your 2nd gasoline. it is totally efficeint and extremely effortless to plumb in. purely be careful as you're extremely becoming a driving bomb.

Answer 8

go with a turbo set up, there are quite a few aftermarket systems out there that would compliment the monster v8 that in lurks in your engine compartment. you Will get more bang for your buck! as far as the boost goes, yes you will have to remap. the fuel

Answer 9

why would you want to do that??? It will just mess up your engine big time. Stick with what you have now......dont think you need that much speed

Answer 10

i think you should bring it to my house so i can check it out and see, oh and you may have to leave it for a few days just to make sure.
