I am considering it - It was suggested by a tuner / mechanic here that perhaps it would be best to take it off, as it would be more reliable, easier to tune and put some money in my pocket for doing everything. Has anyone done this before? What are your thoughts? I feel like this is somewhat of a neutering process, but it seems like it may fit me better, as I always worry about breaking things and hate the possibility of pouring tons of money into my car. I don't take it to the track ever, and from what I recall, since I get on it mainly from a stop and stop at 50-60mph, that may work out nicely for me since the tpi / zz4 combo has lots of torque down low. (I remember beating 11 second GN's from stoplight to stoplight last time it was NA....going any faster would have been a significantly more different affect of course.)

Thanks!

 

easier to tune without supercharging??sounds to me you need a new tuner.

Building a race car or high performance street car will always subject you to chance of breaking parts or increase wear. Factory warranty usually go to 30000 miles/3 years. buy a race engine and your warranty is good till the point you walk out the door with your engine. racing is not cheap.

 

Was the ZZ4 you had in it stock when you beat those GNs? And to answer your question, I don't think removing the supercharger will make it easier to tune. Sounds like you need a new mechanic.

 

Yup, the ZZ4 was stock when I beat the GN's. It is a fantastic car to race in up to 50mph or so ... then .... game over. Had we done some highway pulls, they would have made me look like a saturn Keep in mind, I don't race anymore - that was when I was a kid.

I may have been putting words into my tuner's mouth - he is highly capable of tuning with superchargers, but it does make sense it would be more difficult to tune when I'm having so many tuning issues as-is with the blower.

 

if your tuner has no problems tuning a supercharger, why is taking it off even an option? get him to tune it, if done correctly you wont have any issues...

 

I think mainly because of the problems we've been having with it as it is. Kind of a way to get back to basics.

 

what problems are you having? they may not even be Supercharger related...

 

just as an update, it looks as though I just had way, way too much injector. I had 42# fuel injectors, and an fmu. We are going back down to 24's and see what happens.

 

sounds like your tuner needs some lessons...

 

I don't know about that - I would tend to think that a basically stock car would be easier to tune than a blown vehicle.

 

24# injectors are not going to be big enought to run any apprecicable boost, even with a FMU. If your tuner is suggesting switching to 24's... you have to wonder what he is thinking. 24# is good for a N/A ZZ4 motor, not a supercharged one.

other than you cant get a good tune, what "problems" are you having?

 

We called procharger, and that is what they seemed to recommend (24# fuel injectors) - it is a p600b kit. Apparently they didn't even recommend upgrading the injectors on a stock L98, which I think had 19# fuel injectors - a zz4 doesn't seem to be much different than that.

As for problems - lots of white smoke that smells like gas. No wet spark plugs, no water in the oil, etc. The oil smelled like gas.

 

ok so your on real low boost...

have you done a leakdown or compression test on the motor? white smoke is usually coolant, oil in gas could be bad rings and lows of blow by, way to rich of a tune (42# w/ FMU and real low boost could be the reason for that), the white smoke be a bad head gasket, cracked water jacket, cracked head, etc.

What PCV system are you running?

 

i wouldn't say real low boost - i think it is supposed to be at 9psi. I have not done a leakdown or compression test - I'm not sure exactly what pcv system ... i actually don't even know what that is! Either way, thanks for the help and suggestions!

 

leakdown checks to see if you valves/rings/headagsket/block are all sealing correctly

compression checks rings and bore mainly, but also the sealing of the cylinders

PCV is "positive crankcase ventilation", basically how the air inside the crankcase and backside of the cylinders is managed. It attached to your valve covers (sometimes little breaher filters), hoses, catch can, direct to throttle body, etc.

I would do the tests and see what the results are before you pull the supercharger off, your issues sound like they are not a direct result of the s-charger, but maybe the engine is tired and the boost is pushing fluids around where they shouldn't be

 

I don't know if this makes a difference or not but we haven't been into boost yet

 

then you have problems not related to the s-charger, hoepfully the person who owned the car after you sold it the first time didn't hurt the motor

 

White smoke tells me blown head gasket, I had same thing happen before I put my procharger (d1sc) on, used cheap fle-pro gaskets that are made in freaking Mexico on the orignal build. On the rebuild I used metal enforced weisco gaskets, they cost double of what the cheap fle-pro's, but its cheap insurance.
