What to get before supercharger?

[GoodDayForADrive]

I'm thinking about supercharging my car now, instead of turboing. Seems like an easier install, so I can do it myself, and in addition, the power is instant, and I have no threat of turbo lag. I just need to know how to beef up my engine before I get it... what all will I need? Also, do I need a boost controller or something for a supercharger?

It all depends on what supercharger setup you plan on going with?give me a little more insight and I will mos def be able to help you.
Are you going with a kit?
junkyard supercharger setup
corrado G60 setup?

Well, a neuspeed charger will give you about 140 whp and will be a bolt-on. No internal mods are necessary. Just bolt it on, put on the belt, and swap chips. Ive seen them sell for about 1500 used. keep your eyes open and check the Vortex FI classifieds. The good thing about superchargers is easy install, no lubrication worries, kind of a set-n-forget type deal. If you want high HP go turbo. Have fun either way.

If I were you, I'd stiffen the chassis first and buy effective suspension to control the added power. Next, stickier tires are another option as to not have your tires spinning everytime you use the new power. Also, you might want to upgrade your cooling system because the extra power will most likely produce more heat.

Just the neuspeed bolt on probably, I want to be able to install it myself.

Would neuspeed chip work the best with the neuspeed charger you think?

The neuspeed supercharger chip would work great. thats what it's designed for! But the neuspeed NA chip will not work good at all, it would infact cause your engine to ping and knock due to advanced timing. Get the FI chip and it will run great.

We need somebody to do this to their 2.0... I've never really heard of how well they perform, cause nobody hardly does it.

Too much $$ for the power increase. Although I would be tempted if I were running motronic. Maybe someday if I ever have time to finish my mini-supa we'll see how digifant2 reacts to low boost.

I hear digifant 2 is good for boost until 2,500 rpm, lol. Mabey digifant I is a little more tunable... The injector harness and the whole ECU react differently than the II system.... Mabe you can take this ECU out of my coupe, and the harness and give it a whack.

Digifant 1 is actually a good substitute for going standalone/piggy-back etc.Since it comes from a engine setup prepped for boost from the factory(corrado G60)but digifant 1 from calu on the other hand is poo-poo.
As for the neuspeed setup goodday it should net you some good numbers a guy from here ny had it on his jetta coupe I think he was putting out round 160 or so to the crank pretty good numbers for the setup.I'm not exactly sure but there's a few 2.0 turbo setups for sale now,neuspeed,bahnbrenner,Vf-engineering,and cfi motorsports whcih supposidly nets the most hp/tq out off all of them 200/220 so you have a pretty big plate to choose from depending on your taste and how deep your pockets are

many bmw people have run low boost on Bosch L-jet injection wich is very similar(Vane air meter) to Digi2 I think with a FMU(fuel pressure rises with boost) it could react very well to low boost. Like 4-5psi. Digi has no map or pressure sensor, so it would tend to run lean under boost. In theory you could set the FMU to enrichen the lean mixture under boost. should work, just need to build that charger adn brackets now.

Sorry to get off topic :P

[2002maniac]

May I redeem myself for going off topic? NA motorsports has the neuspeed charger on sale for $2295 thats no too bad at all http://www.namotorsports.net/detail.cfm/part_cd/NS49.10.93
seems like a good price. anyone find one cheaper?

[MKIIVR6]

Down the road the vr will run 8:1 comp and have 23 psi of boost. Should produce around 450-500 whp. That is the plan at least.

[2002maniac]

sa-weet! Good luck finding traction! and when you find it, good luck finding axles :wink:

corey... can I drive??? :D

Before I begin, I'd also like to apologize for going off topic.

Personally, I'd like to tweak digifant for boost applications. I think digifant is the most ingenious EFI system ever designed. BTW, about the BMW system, they are sooooooooo similar to digifant, that they use the exact same bosch air sensor... Here's a I-6 BMW EFI engine:

Note the intake and the air sensor on the airbox.




BACK TO THE SUPERCHARGER TOPIC.

here's a charger for sale.

People say that digi2 is bad for boost but, has anyone tried it? Ive asked many people why it is so bad for boost and they always say, "You cant run boost with a VAM" and that is total heresay. All the BMW turbo kits of the 80's(yes, I know, "dated" technology) such as mosselman, korman, century, etc. used the stock management with a FMU and retarded timing. How many big power turbo miatas still use the VAM? Quite a few. Im pretty sure that I'll never be able to get 200hp but you can still have fun with 5psi and 10:1 cr. Corky Bell built a excellent twin turbo NSX and Doubled horsepower and torque running low boost and using a FMU as the only mod to fuel management. I just want to see what can be done with the poor Digi2 that everyone hates. Kinda like proving a point. :P
