    question for all of you i have a 2007 taco but i was reseching online and stumbled across a website that tells you the hp and torque for any car. now for some reason on the 05 the hp is 245 and torque is 282 now on the 07 the hp is 236 and torque is 266 does anyone know what the difference is between the two and is so what can i do to get my 07 up to that "standard"
    all responses greatly apreciated

    The difference is that the 05 was rated using 93 octane gas and the 07 was rated using 87 octane. The change was required because 87 is a recommended fuel. You can have the 05 performance in the 07 by using the higher octane fuel.

    Wow! is that really true! I mean just on the Gas alone you get all that performance? Come on, I mean if the CAI and Exhaust parts can barely give us HP then shoot why spend all the money on these parts when all we have to do is change GAS! where did you get this info????

    An engine has to be designed or tuned to take advantage of higher octane gas. The V6 Tacoma's compression is almost high enough to require premium fuel (If you have the supercharger it IS required) and takes full advantage of the higher octane. When you run regular gas in it the engine compensates for the lower octane fuel to avoid detonation at the cost of less horsepower and torque. If you put premium fuel into the lower compression 2.7L engine (Or any other engine not designed for high octane fuel) you'd just be throwing your money away.

    In effect the premium fuel doesn't give a performance boost it's really more of the regular fuel hobbling the engine in the name of saving a few dollars a tank.

    ok so what you are saying is that the 4.0 has high enough compression to require higher octane fuel, and if i was to use higher octane fuel i would be getting 245 hp and 282 torqe. but since am using regular low octane fuel my hp and torque is lower. i mean to be honest with you that kinda seems wack. anyway so there is no difference in the 4.0 in the 05 and the 4.0 in the 07 engine wise or performace wise. all it is, is the gas that is being used.

    thats pretty sweet i normally only use 93 octane on my taco. i heard that the difference was due to how horse power was measured. and there is new regulations for it you know.

    This isn't because of the fuel.

    SAE testing standards came into place sometime after 2005. Many manufacturer's were not testing to the SAE standard, and when the SAE became the standard for measureing HP and TQ, many manufacturer's numbers went down slightly.

    To add to what Klown said, The "old" way of testing required that all major accesories to be on the engine when getting dyno rated. NOW, Not only do the accesories need to be on the engine, but the engine has to be breathing thru a factory air box, with filter, and full factory exuast. In other words, its tested just as it would be sitting in the truck. There is still no guide line as to what grade of fuel is to be used when testing, but Toyota and Chevy use 87 octain, unless noted in an add, or in the manual. Nissan, Dodge, and Ford have been useing a higher octain fuel to get their numbers. Also, manufactures can have their engines h.p. "Certified". So far, as far as I know, only Chevy and Toyota have done this. Its mostly for "Bragging rights" for what I know. :)

    X2 to chris. Thats what I heard too. But the kid at the toyota dealership tried to tell me it was because of the fuel.

    But I'm with Chris...

    People at dealerships really dont know alot. Toyota has always rated their engines on 87 unless notted, i.e.the Supra.

    another simple way the horse power could be different was they dyno'd a 05 manual and an 07 auto... as auto's suck little more power out on dyno

    Manufatures H.P. ratings are at the crank. Tranny has no affect on it as it is not connected at the time they dyno a motor.

    Well crap! I have been running 93 octane since day one and from what i read above I didn't need to? Wonder how much money I could have been saving, .......yep, ALOT! Does 93 octane run more clean and keep carbon deposits from building up as bad?

    It has the same addatives as the 87 as Federally required. It will help performance as the programming of the V6 ECU allows a little more power to be made with higher oct. fuel.

    Can any prove with Documents and a Dyno chart about 93 vers 87 in these trucks.

    From my college run by Toyota i was told Octane will not increase horse power allone.

    You need to run the lowest octane you can that will not give you Ping or detination.

    Lower rated fuel burns faster, this is why car wil ping, as the BOOM happen to soon and parts are getting moved at the wrong time.

    Highter Octane fuel burn Slow, I mean really slow. So the pats like vavles have time to seat back in place and get rady for the Booom...

    i am not calling any one out, but Toyota has alwasy used 87 as the base fuel for all cars non turbo and non supra.

    So before we all blow our stack lets see proof of this 93 octane claim.
