If you just do the simple estimations, you can see that those numbers are really high. They are claiming approximately 6 psi, which will not equate to 225whp.

 

Just to let everyone know...according to http://www.superchargersonline.com/h...r.asp?submit=1
you would have to be running about 12 psi to make 225 at the wheels...check the site out though...pretty interesting

 

bump

 

marketing psyc 101 listen to the market, keep people talking about your product. With all the delays that have happened Toyota needs to maintain interest in the sc.
don't belive the hype

 

I call BULL ____!! on SC and AEM intake!!

 

Cool link. And that actually matches my numbes from earlier in the post, so I feel good now :

Quoting myself:
Thats 205 at the CRANK. Car manufactures measure crank HP not wheel HP.

And I would love for the SC to produce 225 WHP.... but it aint gonna happen. That is over 265 at the crank, which for this engine size and power will run somewhere around 12 - 13PSI (estimated).... There is no way Scion is going to offer that much boost on a stock engine. They would have warranty work out the a$$ !

Heh ,heh.... sorry, had to congradulate myself LOL. Seriously though, any calculation method you use should quickly get rid of the 225 WHP notion with a factory supercharger. The SC will come out..... there is just no telling when

 

FYI, the stock exhaust is 2.25", not 2.5". I'm not sure about the diameter of the TRD exhaust. Nonetheless, you're right, there are still no documented power gains w/ the TRD axle back exhaust. As for the rest of what you said... I'm going to leave that be. If you somehow feel what someone does to their car effects your car, no matter how completely different your cars may look, more power to you I suppose.

 

ready: dealer guy tells me something-and i was like WOW. i tell u guys. true/not true, that's what i was told. i have no idea how many psi it takes to do this or how many psi it takes to do whatever else. psi up the a$$ and all around.

 

the STI's numbers are kinda beefed, Car and driver dynoed an STI, ~225 at the wheels. That 300 at the crank is bull____

 

I have a decent amount of experience with forced induction. Consider this:

my 93' Escort GT was claimed 127hp (crank obviously). with 114lbft...anyhoo.. Im running an IHI RHB5 VJ20 turbo (found on the 323GTX). I did the best I could using my advanced engineering math books for help and created a little spreadsheet applet to calculate cfm flow rates for my car. I used best estimates for efficiencies..or actual data on my compressor housing, plumbing design, FMIC design and size, and head VE calculations. I took in account for burn rates on fuel densities for Chevron 93octane (even though best I ran here was Texaco 91)

long story short, hair dryer power, on 9.0:1 w/ 12psi and 2.5" Turbo-back exhaust put numbers around 275hp so about 225 or so to the ground.

Now look at things this way, 2AZ-FE is 9.6:1 and 2.4L whereas my Mazda BPD8 in my Escort is a 1.8L. Most marketed S/C systems are set for 6-9ps for a static compression ratio being under 10:1 (most designs for higher then 10:1 are like 4psi systems). I'm gonna estimate that with a new ECU, larger injectors, 8psi on a 2AZ-FE 200-215WHP is POSSIBLE.

I've been keeping up on the scionspeed turbo set up too... their sitting at 14psi and over 300whp on stock internals...probably wont last 60k miles...but still good show. I'm thinking 6-9ps with the right ECU and enough fuel can be safe/reliable for 200-ish wheel HP.

just my $0.02

g'day everyone

 

Thats not gonna tell you how much whp the tc will have its just for very rough estimates... does it guess your engine size by your computer... sorry but this is useless.

As for how much hp at the wheels will be produced I would guess some where between 170-200hp... I read some where it gains 42 whp but Im sure its a rumor like the rest but 225 flywheel hp is very resonable... either way Im getting it b/c even if its only 40 hp it can be raised with pulleys and other stuff like an intercooler, factory or not, and if zpi ever makes that cylinder head it will work good and get it up to 250whp with some good mods...hopefully.

 

exactly

 

I spoke with a dealer earlier today and the information I got was this...

The SC should be availible in May or June, it will provide an extra 40 to 50 HP (flywheel), and will cost between $3000.oo and $3500.oo.

 

so its 200 to the flywheel... hmm thats not much but probably still worth getting for a decent gain.

 

to the guy above.. if you dont think what others do to their cars effect what people think about YOUR car is wrong. how many pos integras do you see running around with bull____ exhaust, and a intake with stickers and a alum. spoiler? ALOT i had a type-r. and i got ricer this ricer that ____ from people, tinking just cause i had alot of things done to my car i went around street racing, or that i half assed MY car. its almost a sterotype. and YES it does happen. and to yellow, dude your an idiot. and since you believe anything that someone says who wants to sell you something, i have a 24" italian sausage

 

man I hope your right.

 

Could you rephrase what you said to me b/c Im not really understanding where I said I don't think what others do to their cars effect what people think about my car or whatever you were saying not really sure what your rambling on about.

 

the price on the trd supercharger installed is supposed to be $3200. $2600 if u just buy it.

 

The calculations talked about are estimated... but the method i used in my other posts usually hits pretty close... and you are going to need well over 10psi to produce 225 WHP. But I will take 200 - 215 at the flywheel, that would make a very nice improvement.... but we will have to wait to see what really comes out

 

First of all. The date has been changed to TBA because they set the date back once again. Also, the price installed is going to be in the high 3k area. Prob more like 3900.00. There is a 4year 60k warrenty on the product -- thats why the cost is going to suck.
