Anyone have any insight on this? Any good? Where do you get it?

I am thinking of ways to increase the air flow into the engine while I am redoing it. Is there a better way? I do not want to do NOS, seems to 'ricey' to me.

Thanks!! :smash:

I'll tell you what I tell everyone regarding SC. After installing an ATI unit, I would have been better off just going the heads/cam/intake route. It would work out cheaper and better.

Installing a SC is not just a bolt on, there are tuning issues or it will not give you what you expect out of it.

However, if you really want to get the most out of it, be prepared to do some bottom end work. That coupled with the right tuner will give you a great combination.

Also check out the Forced Induction section of this forum for more info.

Depending on how nuts you wanna get, the L98 is not the best platform for a SC. The MAF and the ECM limits are the problem. The SC will max out the MAF. From there the ECM doesn't know what to do. i.e. Doesn't know the engine is getting more air. i.e. Doesn't add more fuel to the more air.

 

Ok, thanks for your input on this. I guess I have to do some more homework. :yesnod:

 

If you decide to s/c, be sure to convert your ECM over to the Speed Density style. It accomodates the greater flow and if you're tuning it yourself, you can mess around with a 2 bar map sensor and have the car read boost (somewhat). The resolution for the 2 bar isn't that great, but it's definately do-able and daily driveable.

Ask yourself several questions when wanting to throw down the money for the s/c.

1. Is the car your daily driver? (If not, go radical on the motor)
2. Do you want to retain decent fuel economy (close to stock) when cruising
3. Do you want to rebuild your tranny soon (if not already rebuilt and updated with clutchpack and shift kit) if you're running an auto. As far as the 4+3, I DEFINATELY don't recommend it for those due to many people having problems with the power and tranny failure. Either way with power in this range, you'd want to, supercharger or not.

If you're in a situation like mine where a majority of your "competition" isn't 1/4 mile but highway punches (not that I promote street racing, it's just difficult for me to say no) then you definately want something to where you don't rely on just NOS. I like having a good bit of horsepower on tap, and that little extra "punch" if there's some real competition (NOS).

Anyway, a decent stroker rebuild can run as cheap as $3k for the motor if you just spend on machine work and parts (doing rebuild and R&R yourself), or you can run a mild 355 head and cam and do decent, but you do lose idle quality and fuel economy. You'd be able to get pretty close to a bolt on s/c kit on a stock block.

Now.. To be real economic and reliable with a s/c!!!
Rebuild the motor with new pistons and rings. Have the crankshaft and rods magnafluxed, shot peened and polished, if your heads are aluminum, have them freshened up and ported, if not ditch them for some aluminum ones(AFR). Get a mild NOS/SC cam(or stay stock if you want to keep the idle the same, but you won't gain the advantages of an aftermarket cam) and throw the blower on.

Not only will you get near stock street characteristics, but when you hammer it, you'll know the s/c is there. But as others have said before, there is alot of money and time involved.

Anyway, the guys on the forum are great! They've helped me through alot of things so never be afraid to post or ask questions. If I'm around and see your post, I'll try to put forth whatever knowledge and experience I've had in the matter.

Either route you go, you're choosing a great platform to invest in. :cheers:
