All right, here's one for you...Has anyone figured out how to squeeze more horsepower out of our tiny little powerplants without spending hundreds of dollars? Theres a ton of stuff floating around on the net but most of it seems like junk to me I.E. "power chips" off ebay...water jacket bypasses for the throttle body...resistors, oxygen sensor fooling gizmos...whats the deal? we are smart guys and gals we should be able to figure this out...I think...maybe?

 

When you say "without spending hundreds of dollars" are you talking about 500 bucks, 800 bucks or even just 200 bucks ?
From what I personally have read and experienced with engines such as our little four-banger, you can really only get mild horsepower gains without compromising reliability and safety.
Specifically for our xB, those ECU and computer monitor add-ons usually work for a day and then they don't, due to the adaptive software in our systems. However, if you do actually do an extensive and most likely non-cost-effective tune, you can get some considerable gains from advancing timing or whatever.
I say, if you want more power, do the I/H/E at least. But you'll be spending those bucks.
There's no replacement for investment when it comes to real performance and reliability upgrades.

Cheers.

 

Indeed...I have installed the Perrin intake and aGreddy exhaust...I suppose I should do the header, but have been waffling as I am trying to justify the expense of either Turbo or Supercharger. I was hoping that someone more intelligent than me had figured something out to save me from the two thousand dollr plus expenditure previously noted. On that note what have you heard or think about either of those options? Thanks

 

ah, go for a lightened pulley also. i forgot to mention that. i personally have the agency power, though perrin might work with your system better as you have their intake already. it'll free up some spinning mass and give you quicker revs.

as for the turbo and supercharging, both systems are generally well tested on our engine.
GReddy, HKS, and ZPI make turbo kits for the xB (though i'm sure there are a few more out there that i'm forgetting). GReddy has been the most popular around here i think, though ZPI has good results as well. The thing with ZPI is that they are under a bit of controversy right now (you can search that and see what i mean).
PowerEnterprises, Blitz and GReddy make superchargers for us (again i'm forgetting a few).

The differences between the turbo and super charging systems is that generally on xB's that i've read about, the supercharging route will give you the least headaches if you don't want to worry about tuning and recalibrating and reliability all the time. Superchargers tend to give a 20-25% bump for us. Given you have the intake and exhaust, i would estimate a 130 WHP output if you slapped one on.
Turbos for us generally require a lot more tuning (again, search for turbos and forced induction, lots of good stuff to read up on) and can be pretty unreliable without proper maintenance. However, if properly maintained and tuned, they are solid systems and can give a much bigger boost than superchargers can (typically 25-50% for us).

in my personal opinion, while i love turbos and the punch they give, i would personally go with a power enterprise supercharger on my xB if i were to go blown. but that's just me.

 

I am pretty familiar with the different situations regarding types of forced induction I was just wondering what you or anyone else thought, and appriciate your input. As far as the blowers go there is another one that is doing the cetrifugal type like Vortech I think the name of the company is Power something (supposedly made the first production cetrifugal blower in Japan)or other, they also make a VVTI controller to alter the valve timing on our beloved wind up toys. Anyhow I am more curious with the effects of turbo lag V.S. turning the blower off the crank..stuff like that. Also the blitz blower has the electric clutch to adjust the amount of boost...what are your thoughts on that?...practical or Mad Max? So the pully makes a difference? I had my doubts but I suppose lowerinf the rotational mass can't hurt? Thanks

 

I think you might be talking about Power Enterprise. they do have the controller, CAMCON.
check it out here: http://www.powerenterpriseusa.net/ca...ges/bb/bb.html

as you're probably familiar with, the turbo lag might not be too great in our engines because of its small size and given the setup of the above said turbo systems. also as you probably know, running the supercharger system will give you basically constant boost throughout the powerband, while the turbo will give that noticeable kick. i personally have not ridden in FI xB's, but i've heard that most turbo systems do have the noticeable kick period, while the superchargers have the more linear approach.

as for the blitz, i think the switch they have is there for precaution. i think it's pretty wicked. very practical. why run high boost when you're just cruising around city blocks at 2K ?

hope this helps.

 

Indeed again...It is Power Enterprise I was thinking of there is a local shop here in AZ that sells thier stuff...Vivid Racing, super nice guys and will get your stuff pronto. I would tend to agree with the clutch alanogy...why use it if you don't need it!...Thanks... Anyone else have any insight?

 

Here is a tip I found from the Diesel Work we do at our shop. The automatic transmission looses some of it power to the wheel thru "clutch slippage" this is designed into the transmission so old ladies get a nice smoth shift. If you use a fluid designed to "lock-up" quicker you will get more power to the wheels. Here is a quote off the Bully dog web site;

On the Dyno just adding this Bully Dog's Rapid Power ATF allows 50 more rear wheel horsepower to make it to the ground on a transmission that is slipping. The only oil that should be in your transmission is Bully Dog's Rapid Power ATF.

Now here they are speaking of a 500hp diesel gaining 50hp which is about 10% increase to the wheels, so on a 100hp Scion the gains should be about 10hp to the wheels.

The Fluid Bully Dog uses is made by Redline Synthetic Oils and is their Racing ATF, I have talked to the engineers at Redline and they assure me this is safe to run in our Automatic Transmissions the only problem may be the torque converter may lock-up to quickly and cause a shutter. I have had this fluid in my Super Charged xB for about 6,000 mile with no problems. It does seam to shift a bit quicker and harder. I have never had it on the dyno so I do not know if it has any more power to the wheels but the seat of the pants dyno say YES.




You can buy it here...you will need 4 quarts

Hope this helps some of you folks!

 

I'm surprised your tranny has survived 6 K with that fluid in it. The Toyota Tech IV is the only 100% compatible fluid and I've seen people try other stuff and end up burning up their trannies.

 

same things you would do if you had a manual.


lightweight pulley
intake
header
full exhaust
throttle body spacer
engine damper
iridium plugs
ground wire kit

 

"I'm surprised your tranny has survived 6 K with that fluid in it. The Toyota Tech IV is the only 100% compatible fluid and I've seen people try other stuff and end up burning up their trannies."

Redline has been around a long time and know what they are doing, we have many customers running this and other Redline product for 100,000 + miles with no problems.
The biggest enemy of the Automatic Transmission is Heat. Reline Synthitic Oil Dramatically reduces friction and metal to metal contact in the pump by forming a unique lubricating film. Thus reducing Heat!

It demonstrates incredible lubricating film strength capable of withstanding loads of up to 1.4 GPa (200,000 psi). Lowers the temperature at which typical hydraulic oils will flow by up to 10 C and reduces the risk of cold start up wear. Friction reduction dramatically lowers operating temperatures, adding life to pumps, seals, hoses and oil, and improving clutch engagement.

I also personally run this fuild in an Automatic on a car that make 1000 WHP, we can get about 300 passes down the 1/4 miles with is fluid. We regular fuild the Trans will fail about 100 passes.

Hope this will help you understand.

 

The reason that it's tough to get more out of our little engines is that they're already very highly tuned- EFI, VVT, tuned intake manifold, 4 valve high compression hemihead combustion chambers, headers, low restriction intake and exhaust...

Plus the fact that it's undersquare, a stroked version of a 1200cc motor... they have really good driveability at low rpms, in relative terms- I have to remind myself to gear up more often for better mileage...

Short of radical means, there's not really much more there... I tell my coworkers that it really wants to be a fast car, it's just displacement challenged, which is really the truth...

 

Probably true! I just wish I could get a little more out of it ...I guess I will have to opt for the supercharger and then see what happens...Thanks for the input

 

i added volant intake...mmw 4-2-1 header...trd exhaust...works for me........

 

I have a Perrin intake and Greddy exhaust (sp2) I have been holding off on the header because I could'nt decide between a turbo or supercharger...still really haven't...??? What to do???

 

good intake and good exhaust do the dc header or any header you want you hp will go up 7 and you will have wayyyyyyyyyyyy better flow in your exhaust and if i were you i would get the greddy bold on supercharger because with the turbo you will have to run higher octane gas

 

You'll need to run premium gas with any intake boost system...

And, of course, you'll need to upgrade the clutch at the same time, just so it won't break at an inopportune time...

If I were doing it, and I'm definitely *not*, the I'd investigate this route-

http://sgpracing-store.stores.yahoo....nscbbsuki.html

Along with an aftermarket axleback or more...

It's very similar to the factory setup on the tC. Near as I can tell, it doesn't require any changes to the electronics, which can be tricky- just basic nuts and bolts...

I'd contact any vendor and ask a lot of questions before buying anything...

Kit, clutch, and muffler will run almost $4K, just for parts, and I'd expect reduced fuel economy and engine life, depending on how much boost is applied... and kiss the powertrain warranty goodbye...

EDIT- you have an automatic, so the clutch stuff doesn't apply.... dunno how the auto would hold up, or if aftermarket shft kits, etc, are even available...

 

oh, ask your dealer about the blitz if you're willing to deal with your dealership (i know, it's a long shot, but hey) because i think the blitz supercharger is actually supported under warranty by some dealerships via the scion marketing or whatever. at least it's supported by my dealership. just another option.

 

noob here
um duz this apply 2 my xA aswell?
thnx

 

^^^^ yeah pretty much.
