Does this seem kind of low?

Dyno:

 

Lol for the price of the TRD supercharger you bet your a$$ a 14hp gain is low!

 

i think it was a 14 HP gain by adding the new pulley. if thats the case.....the pulley was a great investment

 

Correct, no stock auto tC dyno's 154whp. But the S/C'er (unless you got a super deal on it), is not worth it on an Auto tC. It's "barely" worth it on the 05-06 manual tC now since they dropped the price.

 

That seems just about right! Its really sad... my gf had the same setup. Supercharger, 9.5 pulley, new belt, Forge BPV, DC Sports Header, and got 16x hp and torque like you. The auto tranny really sucks and sucks even more when a supercharger is applied. For this reason she decided to sell her tC and buy a Mazdaspeed 3 which now makes over 100+whp more than her tC lol. During the dyno, Toan at Ptuning said that it was running extremely lean and that adding fuel might increase hp a tad. So if youre intent on keeping your setup consider adding meth injection to increase power and safety.

 

She should have bought a manual tC. If she plans to upgrade that MS3, be extremely careful on what you do to them. They tend to blow a lot.

 

Yep, that dyno is pretty much dead on.

 

hm.. but the OP has stock header. and still has 166 hp.
and btw you cant say that he has +14 hp than stock because auto tc might not have as much whp as the manual stock tc has.

but if the op wants to keep the s/c i would get a weapon r header, weapon r s/c intake , megan s pipe and mid pipe.

you could brake in to mid 170hp or maybe close to 180

 

The +14whp was from the pulley upgrade where it says stock is the baseline with the original s/c pulley. I'm pretty satisfied about this part compared to the rest of the setup this was the best bang for the buck. NST FTW.

I'll have to look more into meth and a FIC in the future. In the mean time since I added the s/c the car has shown a tendency to run rich (sooty tailpipe). Based on the other threads it seems 9.5 pulley should put the car within the upper range of the TRD tolerance.

Appreciate all the comments regarding the accuracy of the total HP I figured as much as we did the math in the shop (checking to make sure we entered the right ratios) and it works out to about 200 at the crank. I was kinda disappointed to see how much power was lost due being an auto tranny because I see much higher numbers on the manual dynos ~190whp with an equivalent setup.

So the I/H/E would give approx 10whp? What about just I/E? I'm not sure the rasp that the header adds is worth the level of gain it returns.

 

Man.. that sucks...this is why I don't dyno my car...I don't want to be disappointed...

 

Don't have high expectations and you won't be disappointed.

 

its dead on. stock tc dyno's at what? 136/138? while a 5spd dynos at 148ish? the megan oe-rs is jus a restricting as stock IMO. This is why the trd charger is useless for that amount of money, but try adding a header/intake/pulleys/engine managment/3" exhaust and maybe it'll go up sum.

 

Ive heard the TRd tune pulls quite a bit of timing and im thinking on the auto ecu it may pull even more to keep the s/c "Safe" for the auto tranny. I bet you could get that close to 200-205whp with a stock ecu - using fic/ultimate for fuel/engine management - and a 4-2-1 header and full exhaust.

x2 my boys got one and hes to do anyhting more then cai & exhaust

 

wait... that's all the power you get out of a supercharger for over $3,000??? thank god my friends made me go the turbo route.. I almost brought heyitzmee supercharger

 

I just installed my 9.5 pulley last weekend on my manual 07 tc. It felt like a 14-20 hp jump. But im glad I got my s/c for $1300 new in the box and installed it myself!
thanks lasrx for posting numbers

 

5spd>auto though

 

Yea its hard to imagine theres that much power loss through the auto vs 5 spd - baseline dyno on an 08 auto was 139whp here locally - thats only like a 15whp gain with the stock pulley. I have a friend here with an auto that dynod 208whp with a 75 shot - stll holding up great 2 years later. Also i know of one person with a 5 spd s/c that made 203whp on the stock pulley - i just cant see a ~50whp diff between the 5 spd and auto - i can see 15-20 but not 50.

 

wow i feel shamed of the auto trannys ( i have auto too)

 

why get an auto if you KNOW you are going to be upset about it?
