Whats the max amount of HP you would gain from customizing your IHE? Even if you buy all the top names. Also, is it worth the money considering TRD dropped $1000 on the price of the SC? Does going SC mean i HAVE to change alot of things and end up paying 3500 anyways? I want to get close to 185 190 at LEAST with the least amount of hassle and pay, but if SC is the only way then ill just save, but if i have to pay 3500 then I'll pass on that grass.

 

ok i/h/e will equal around 20whp gains...so 160whp

s/c will get u to around 200whp.

if you do i/h/e and s/c...u'll see even better results for around the original price of the s/c

 

You will never begin to touch the power per dollar of boost with those mods. Intake gets you pretty much nothing, header moves power around the band (so you will gain some at one point, lose in others in most cases) and exhaust will get you a small gain. If you are looking purely at bang for your buck, the SC (a turbo is a better way to go just for power per dollar) wins out.

 

Think you mean 200bhp. Scion advertises the SC will increase power @ flywheel from 160 to 200 (bhp). So, generously assuming a stock manual gets 140whp, - and keeping same ratio of whp/bhp - the SC alone would give about 175whp.

With the SC price drop to $2130 + $500-600 dealer install + tax, you'd have to buy header + exhaust to get to your goal of 185-190whp. By then you'd be pretty close to $3500 ...

You're pretty close to turbo money then, and getting significantly less whp.

 

there have been a few people on here dynoed with s/c and exhaust alone that dynoed at a little over 200whp

 

Stock S/C dynos over 190.

 

stock s/c dynos right near 200 WHEEL hp.

 

OK, can someone kindly link me to a dyno of otherwise stock tC with S/C.

Checked F/I dyno thread but all S/C's had exhaust and/or header, pullies, etc, etc ...

Honestly, my interest into S/C's ended when I read about broken brackets & dealer install snafu's. Just skeptical about a supercharged tC approaching 200WHP without mods ...

thanks

 

From everywhere I have have heard and read, the sc is pretty under-rated and usually pulls about 190 whp or so. I can try to dig up dynos, but honestly since I autox and could care less about drag racing my fwd I dont follow the FI stuff as much.

 

Here is one thread on another forum I post on all the time. The third page has a dyno for the stock sc hitting 184 whp. I know there are more out there (And maybe in that very thread).

^^Thanks, 184 is still more whp than I expected from stock S/C.

This is the kind of info I'm working off, from the tC home page:

https://www.scionlife.com/scion/tc/

 

^^well that's why...doesn't the supercharger kit come with 7 psi of boost?

 

I am still not impressed with it for a few reasons:

Low power/dollar
Centrifugal design (so you dont get the more linear response that most expect out of a supercharger relative to a turbo)
Reliability issues they have been having

If it were a well built roots charger I would be much more impressed with it, but it would be tough to fit one on the tC due to the way the engine sits.

Here you go...about a 1/4 of the way down a guy named dachmo only has an aftermarket midpipe and is getting 210whp with that and the s/c kit which remained unmodified...stock pulleys
and i doubt that midpipe made up 10whp or more so there ya go

 

i/h/e and pullies and emanage ultimate and slightly larger fule injectors or more pressure either way. saw a guy at a local shop post up 181.2 WHP and 178.3 TQ at 68 in shop temprature car at normal operating temp. thats what im gonna do i think i dont wanna shell out 3 grand when i can take my time and peice it together with the best deals possible and ge tout for under 2 grand and have mabey 10 less horsepower. ____ you acn port and polish the heads at that point and be up with a SC i would guess

 

Im thinking with I/H/E and other supporting mods and a GREAT tune will net you the same power if not greater WHP than the SC, plus it will be more reliable if you have a GREAT tune.

As stated above, those mods, will net that power most definately, but with a standalone it has even more potential.

I think that 200whp is plenty for a DD, and that is attainable via F/I or N/A.

its all about how much effort you wanna put into it.

 

^^^ so true an NA car is what you make it you can make crazy power NA spending the same 3.5K. oh and nothing sounds like a built NA motor... nothing its pure sex

 

Like I said, I read this thread already. This guy hasn't posted a profile so we don't know exactly what all he's done. BTW, if you read his post again you'll see his S/C pulley is not stock.

Not trying to argue with you, but 184whp is not great power for the $$, even with the price cut. To get the kind of numbers you're expecting from the S/C without header & exhaust you'd have buy an a/m pulley, increase boost, buy emanage and re-tune -all of which I would expect would void the warranty.

And put you into turbo $$ range without the corresponding whp gains.

 

building this car NA is not a dollar per power friendly option in any way. It is fun, and some have had good results, however with getting head work done to get the power. IHE is never what you think it will be in the long run. Intake gets you almost nothing. Now, if you want to sleeve it and bore it, raise compression, custom head work, tuning, etc then you will push much better numbers, for a LOT more money than a turbo kit. I am all for NA power, and am interested in possibly seeing what I can do in that area at some point, but I also accept that I could get better numbers for less money running FI. Dont get too caught up with the manufacturer claims for bolt ons and the widely varying dyno stories and sheets you see.. hell, you can find stock tCs dynoing from 135 - 150 whp depending on who ran the dyno and which type of dyno it is on.

 

Here's some relevant I/H/E vs. S/C numbers from June issue of "Modified" mag. Pg. 132, their tC project car.

stock 5-spd: 139whp / 145 wtq

add AEM cai, DC Sports header & axleback: 154whp / 156 wtq

delete cai, add dealer-installed TRD Supercharger, CAMCON, ARC airbox, tuning on the dyno, keeping DC Sports header & exhaust

= 209.78whp/183.04 wtq.

Total $$ spent = not specified (but if you have to ask ... )
