I was just on Hasport's website and noticed they sell a Jackson Racing supercharger made specially for the b16 engine in an 88-91 crx or civic. It was something like $2600. What are the benefits of a supercharger vs a turbo? Are they more reliable?

What are some of the downsides?

 

no wait for the boost. turbo you have to wait for it to wind up, supercharger its operated by a pulley so you have the boost from the start!

 

The downside being you can't get as much power out of it? Also, since a supercharge doesn't require an intercooler, does that mean I can keep my A/C?

 

I belive that you can keep A/C. But as for not getting as much power, if your using it to race having power from start is going to make your numbers better then if you only had it from say 3300 on.... at least thats what I would imagine, 1/4 mile at least

Yes you can keep AC.

And with a turbo it's not the intercooler that prevents you from having AC, it's the turbo manifold. But they have turbo manifolds that are AC compatible.

 

Is a supercharger more reliable than a turbo setup? I've heard that a turbo setup isn't very reliable in our cars.

 

Most of the JR superchargers only produce 5-6 lbs of boost and come as a complete kit. They only give 40-60 extra horsepower, but are usually stone reliable and because of the low boost, won't hurt your engine.

Sounds like what I might be looking for.

 

A few years back, Honda ace Ron Haase tried a jackson supercharger setup on a track-only crx and could not keep it from blowing head gaskets......Someone from Honda (Endicott?) said that that particular motor (D16A6) was not designed for, and therefore would not ever stand up to that much pressure.......Maybe street driving is different....Maybe the new style head gasket is different.......Anyone heard from Ron lately????????

 

turbo is just as reliable as any supercharger, ppl are just dumb asses and cut corners with turbo becuase it requires more parts and customazation. tuning is KEY with turbo, if you have a good tune you can make endless power and run ALL DAY

 

What kind of gas mileage would I get with a supercharger? Because I've been thinking about this setup for a long time but the car is a daily driver some I'm not sure.

 

If you stay out of boost I have heard that backpressure may create an additional 2-3 MPG, and my friends turbo'd cars seem to get fairly good mileage as long as they dont beat on them.

 

Oscar Jackson himself was running a B16A with one of his superchargers hooked up to it. The car made 212hp and would run run high 12's. I thought that was a pretty good setup for a reliable daily driver.

Heh. That sounds like a damn good setup. Also the supercharger install sounds less complicated and therefore less prone to problems.

 

if ur dealing with a B-series engine or a D-series engine trust me . . . Turbo is the known for the common direction if u wanna increase an amount of HP just by bolt ons . . . but after all . . ALL - MOTOR BABY !

 

Still want to know if anyone has this setup. Anyone know how reliable it is, compared to a turbo setup?

 

Hmm personally if I was to build an engine, and I hauled all my friends and crap around, I would choose a SC, but for the fun aspect turbo is the way to go.

 

It is a DD, not a track car. I love "spirited driving", when it's safe, so power gains are always appreciated. Also, I love the sleeper look of a clean EF civic..

 

Well lets see, your gonna make about the same power, it's all about how YOU like to drive, nice torque in the low r's, or do you want to beat down people on the highway.

 

So a 6psi SC is gonna make the same power output as a 6psi turbo? I thought SCs were less efficient because they don't use the wasted energy from exhaust output, and run directly off an alternator belt?

You are correct. A supercharger will make less power than a turbo at the same boost level.

I remember a comparison that I read a while back where a company (I think it was Drag) did a test to see the power differences.

They tested a Jackson Racing supercharger and turbo kit at the same boost level on the same engine, they dynoed the car on the same dyno etc. The conditions were replicated in both tests.

The turbo system made like 40 more horsepower than the charger at the same boost level.

And you are correct about the reason too. Turbos use energy that would otherwise be wasted while superchargers create parasitic (sp?) drag on the engine.

Both have their good and bad points. To the OP, just make sure you do your research before making a decision. You don't want to go with one and then decide later on that you would rather have the other.

 

Dont know about the B series but I have one n my D16a6 and love the power it gave me but just like the turbo kits the firts thing you want to get rid of is the FMU and stock injectors. I have 450 inj and a tuned ECU these two things will be way better than the stock kit and then you can up the boost. My d series CRX is faster than a swapped ls CRX.

 

I guess my main concern is reliabilty. Considering this is my DD and my only car, it breaking down is not an option. If a SC breaks down, can you just remove the alternator belt and run the car normally? Are they more reliable than a turbo setup?

supercharger isnt more reliable than a turbo

Your car is as good as your tune and plus with the jrsc there are little upgrades (11psi pulley maybe) turbo your options are endless. With my stock internal b16a i made 275 whp 190 torque on a mustang dyno.

Is that really your main concern? If it is, then you should really consider turbo.

One thing you should consider before making your decision is fitting a turbo system under your hood.

Sure, it can be done with a b16 in a CRX but you may have to change a lot of things around to get it to fit. Also, you may need to get rid of your bumper support, which would cause severe damage if you get into a front end collision.

I had a turbo on my last car and I loved it. Absolutely a blast to drive and I never had any reliability problems, even at 12psi on a stock engine. Like already stated above, reliability is 99% in the tune.

On the other hand, I now am working on a 90 Civic hatch that has AC. I want to keep AC. So, I will have limited options as far as forced induction. In this case, I am considring doing a simple supercharger setup or maybe even a remote turbo system.
