Heres the second vid guys. You can see the car doing well, then the brake fade was obvious.

nice video but whoever the camera guy what is a flamer... my word... no offense if he is ur friend, or maybe they were just joking by talking that way... but its actually kinda funny to listen too haha.

 

who put your turbo on. I want to get a turbo or supercharger and Im just getting info.

 

been the turbo route before with my mazdaspeed protege had bad luck im planning on supercharger for the xB

 

I bet you people trip out on the xB when you take it to the track. Then when they see the turbo, they really trip out.

 

I really want a supercharger just because I think trouble shooting a supercharger would be easier than a turbo.

 

i have to agree mat18 ive never had a supercharger, but from what i understand they are safer on your motor, and its alot less of a hassel.

 

That cant be further from the truth. There are too many "I heard this from someon on the forums, etc." I'd really like to know why a supercharger is safer for your engine? You're boosting just the same but instead of your exhaust gas spinning a turbine, your engine is running another accessory...the supercharger.

The guy recording the run was my friend but he was not the one talking. Another one of our friends was talking to a GT2 pro racer about the M5 we brought there.

 

I don't want to start a war over which is better superchargers or turbos they are both a great thing for the automotive world. It has been common knowledge to me for years that superchargers cause less stress on the motor, but I can see your point you can push anything to far and cause the same results. I have had some bad experience with turbos and all I am saying is that next time I am trying the other side of the fence.

 

I'm with Rollhard on this one.

Boost is what "causes stress" to the motor. And you know what? Boost, is boost, is boost. Whether it is coming from a supercharger, or turbo. A high boost supercharger is far more stressful to a motor than a low boost turbo. Sure you can throw in factors like intercoolers and such. Bottom line though, like for like one is not more "stressful" than the other.

Each have their advantages and disadvantages. Do your research, and talk to knowledgeable shops. Not just "So and so" on the forums. Get educated, and make the decision for yourself.

And even though Rollhard didn't say so. I know that his shop could do either a turbo, or a supercharger install for you Mat18. The shop Rollhard used to be at did the original install on that Greddy Turbo. Since he has been with Race Precision they have been working on tweaking the install to see how much potential the 1NZ-FE has. (As well as the Greddy Turbo.)

If I am mistaken on any of this I am sure Rollhard will jump in and correct me.

 

well said...

 

Im not here to start any wars or arguments either. I would just like to know the theory behind all the BS that is flowing in the internet these days. I guess the crap stream has found a way to flow into the virtual world. I wonder who started the "a supercharger causes less stress on the engine" theory. It would be more sensible to think that something that is "belt driven" would cause more engine stress pound for pound of boost than a turbo which uses exhaust gases that are coming out of the engine anyways. Im not trying to single you out knoxbox, I'm just trying to make sure that things arent said just because joeblow heard it from someone who heard it from someone who heard if from somone who thought they knew what they were talking about. Its really mindblowing the kind of things we hear being in this business. Its like a customer coming to me and telling me that their multiswivel bifocal muffler bearing was loose and that was why he was running too rich and detonating.

 

by all means single me out... it wasn't something i picked up from the internet which you seem to mistake, but thats fine. to assume only makes an ___ of u and me. It has been something that I have always heard for the past, 9 years that i have been into cars. Never really took the time to sit down and see it how you put it, it was something I was told and, i'm not the first to say it im sure, I have heard many other make the same statement before my saying. So don't think of it as something like, oh i saw it on the internet it must be true, cause thats just not the case. But the way you and rton put it makes since. to much of a good thing is a bad thing basically. which is why i said well said... and let it go at that. I will admit when I am wrong.

I never really did any research into the subject matter, another reason I and many other could possibly be heading to that direction is the fact that you just don't hear about supercharger problems as much, or in my experience I haven't. We can just leave it as another mystery of the world if you will as to were it all started..., but i hardly doubt the internet is at the core of this.

 

I dont want to single you out because its not fair. Heck man, I have fallen victim to this also. Even being in this business we learn things from our network of shops, etc. I have learned things from mechanics from other shops, tuners, etc. I now know not to believe much of what others say because when I started to get deep in to this I found out how little most shops know. There is a mathematical science behind everything we do to our cars. How we make power, why we make power etc. I can guarantee that over 80% of companies out there that claim to make "performance" parts for your car have no clue on how to make power on a vehicle other than larger piping, more boost, etc. Im not sure why the supercharger guys are not having the same problems as the turbo guys. In fact, there are no problems at all with my turbo car now. If someone has a problem, pm me, bring your car to me and I can explain to you how things work. If we think about it for a second...okay, maybe a minute, its quiet simple. ECU thinks the engine is NA, you go FI so we need to run more rich, ECU sees more fuel and tries to cut back, a reliable tuner will know that it still needs more fuel so he adds more, ecu doesnt understand why there is so much fuel so the CEL comes on. Some people dont understand that concept so they think that the CEL is coming on because there is a "problem" with their turbo set up. In fact, there is no problem at all. If the sc guys are running a good afr, they should get the CEL as well. If they dont, chances are, they are running lean. Now, the difference in reliability between supercharger and turbo is fun factor and engine stress. Modern superchargers are designed particularly well and there may not be much stress on the engine. When you drive, boost comes on smoothly and you get a linear powerband. With a turbo, you'll have lag so power is more peaky. That peakiness is what I like about the turbo. You hear the spool and the power kicks in. Its a lot of fun driving turbo cars in that sense. Stress to the engine would probably have to go to the sc though as the engine is still working to turn that charger. The way I think of it is a wind mill being powered by some amish guy inside pedalling his heart out (in this case the engine turning the supercharger) or a windmill that is simply powered by the air (in a turbo's case the exhaust gas).

Of course the engine isnt working nearly as hard but you get the idea. lol.

BTW, sorry for any typos. Im typing fast and my wife is telling me to come eat dinner. haha

 

thanks for explaining it to me, i appreciate it. I try not to get to caught up in that kind of stuff as well but when you hear the same thing from numerous people... you start to wonder were the trueth lies. trueth in the masses. hrm....

 

NP at all man. thats what the forums are here for. Im glad you posted it though because I bet there are others who maybe wondered the same thing but never brought it up.

 

this is true.

 

Man... Rollhard... I thought you said you wouldn't mention the bifocal muffler bearing incident!

 

what about the blinker fluid incident.

 

ARgh, sorry man. I did promise not to mention unless you brought up my hydraulic ventilation caliper spokes. DOh. Sorry bro!
