Instead of calling him an idiot and pointing out "what he did wrong" because you're all in denial that you're beloved Blitz kit didn't work very well, maybe we could be productive and figure out WHY it's not making as much as it should.

first off: octane does NOT make power Octane reduced the chance of detonation, or ping. If the engine wasn't pinging with 87octane, then 87 is fine in the engines current state, but that would leave me to believe that it might be running rich if it wasn't pinging with 87octane, which would impair the engines ability to make the predicted power.

Another thing, which was mentioned a little, was that modern cars like to be in control ALOT more than older cars. When the WRX came out, people were having a hell of a time flashing the ROMs, the Subaru would some how go back to it's factory tune level. This could be the car protesting the blower.

One thing I'd do (you may have already done this) is double and triple check the elctrical connections on the Blitz piggy-back. Hell, maybe even try removing the piggy-back and seeing what happens. Maybe a boost leak also, but doubtfull, it'd be louder, and you ARE a mechanic, so I don't think something as simple as that would be the problem.

About that piggy-back, seeing as this is actually for the Ist/bB, not the US spec xA/xB, you may have some contradictions between the computers. Japan has a slightly higher octane rating (no, not 97-100 like everyone thinks, they use a different scale, it's somewhere around 95) and that would allow Blitz to advance timing a little bit. The xA/xB however, might not like this because of many things. The US Spec engines MAY (I don't know for sure) have knock sensors, which would pull timing back at the sign of ping, or it could be due to OBD-II and it's ****-like controls.

The plug argument has less base than everyone says, yes, Blitz says it's good to get colder plugs, but everyone remembers who sells plugs? That's right, BLITZ sells plugs. Since this was a low rated power increase, if the stock plugs are in good condition (which being a newer car, they'll be fine) then the plugs won't matter. Checking to see if they were gapped to factory specs might have been a good check, but not necessary. Plugs are only needed if the car is missing, because turbulence from high-boost inside of a combustion chamber can cause the plug to blow-out.

Hopefully you're still able to do some checks on the car, it's probably been delivered, though.

No Blitz love here, but if you add boost to any motor and you don't use decent gas and colder plugs... You honestly think that it doesn't make a difference? Who cares what this customer wanted, you're spec'ing a product under misuse. Edit your dyno info, delete it all together. It is useless information.

Hey guys look at me i'm a mechanic and I can install things improperly because the customer asked me too, and here is the outcome! Look this product is crap! it must be because the product is bad! Don't buy it!

I'll trust the dyno results of the people that do it right and have done more than one install of a supercharger in their entire life.

bring on the tuners

 

Yeah, the Supercharger isn't worth the money, my import tuner magazine had a little article bout the Blitz SC and it didn't make that much of a difference.

I mean you'll feel the difference but I wouldn't pay $3,000 for it, maybe if it got to 160 hp then yeah.

this is correct octane doen't make horsepower ,however timing does and the knock sensors on the toyota is very sensitive and will pull timing at the drop of a hat if thats whats happing the power will fall off fast.

 

Welcome to the world of overpriced, underperforming crap that is Blitz. Normally I say you get what you pay for. That rule might apply to things like the quality of hookers and first class versus coach, but when it comes to Blitz it is just the opposite. All your paying for is the prestigious "JDM" name. What a crock. Blitz is right below APC in my book.

 

Import Tuner mag (yeah... it's for ricers...) reviewed the kit and had a exact same as you.

It is the dyno tested hp. and 20~25% of current power sounds right for the claim Blitz have been making...

I hear you though... $3500 sounds like it will get you more juice....

So, you can't feel the increase of power/torque when you drive?

 

xero, have you installed this kit?

I didn't think so.

Today i was talking with the editor of turbo magazine who drives a supercharged xb, and they got the exact, i repeat, EXACT same results as the xA. they had the same intake and exhaust too.

Oh yeah, the xB had the recommended colder plugs from blitz, and was running 91 octane.

Granted they are two separate cars and engines, and all engines will perform differently.

Point being, that you will not see a huge improvement in performance with the colder plugs and 91 octane. I also recommend these two things , and if it was my car, I would definitely changed them.

I've said it before and i will say it again. it wasn't my car, i don't deal with the customers. i recommend it, but if they don't wanna do it, oh well. stop giving me crap.

I gave an honest impartial review of the blitz supercharger, and i stated the test conditions under which the dyno test was performed.

You are more than welcome to go out, buy the car, the supercharger, and pay for the dyno time and do this testing yourself. chances are you will get similar results.

I have a feeling that some people are flaming because the kit doesn't seem as promising as it once seemed.

On flywheel, xB's hp is claimed to be 107hp. And Blitz claims that their Supercharger will bring it up to 150hp.

On dyno (wheels), xB's average seems like it generates about 87hp. And if the Blitz kit brings it up to 107hp, that is about 25% of the power increase. And it seems like that's about the average number people have been getting...

Doesn't that sound about right?

I know it's an expansive kit.

20hp is not worth 3k. Plain and simple.

 

The best thing you can do with the $3k that you might have spent on a Blitz supercharger, is trade your Gen 1 xB for a Gen 2 xB, or anything else. Let's face the fact that the Gen 1 xB was and is one of the slowest cars in production. As such, the first $3k spent for any Gen 1 xB owner (myself included) should be to drive something less humiliating.
The car is embarrassing to be seen in.. and no matter how much $$ you put into the car.. it's still embarrassing. In fact, after a point, when it looks like you're trying too hard, it gets especially embarrassing because it looks like you're trying to impress people with the cheapest/slowest/most humiliating car ever made. Buy something else.

TRUE but this kit on my car = FUN....

 

you woulda been better off buying a Greddy turbo kit then a supercharger srry to say...you should def check out Ptuning.com. their main mechanic actually is the owner of the fastest xA ever w/ way over 300whp. hes actually worked on my 05 xA alot personally

 

Actually, it would be more embarrassing to own a Vette and get smoked by a xB1. Heck my xA traps faster than a GTR. It can be done, people just approach it the wrong way. I used to have the Blitz kit years ago, and I was able to get it to punch out some power ( main problem is the factory 4pk belt
width). Many people don't realize they aren't hitting full boost with the kit because they are running the provided Bando belt or another cheap belt. But yea, I eventually scrapped the blitz because it just isn't suited for the 1NZ drive belt design.

If you are superficial about cars ( as it seems you are), then building a vehicle with blood and sweat isn't for you. Go to the dealership like the rest of the population and throw your down payment at the sales guy and pick up a car.
Like I say, there is a lot more enjoyment out of building a car instead of buying one. Not that I'm into street racing anymore, but if I were.... I'd have a lot of loot. And you would be betting on the wrong car.

You see a car for what it is in the brochure.... I see it for what it can be.

I also had a bad experience with the Blitz. Although I got mine for $650 bucks. That's why I bought it.

What I've learned....the hard way.....But a car that CAN make gobs of HP. And keep the Scion for MPG.
