+20-30HP ==>possible with bolt ons?

I really want to be in the close or near to the 300hp range. Is this possible with an intake and exhaust upgrade? (plus ECU tweek). Will TRD parts do the trick without a warranty void?

If this is a ridulous question, please remember that the last time I modded a car was in the late 90s as a teenager. I have to admit coming from my 4cyl MT Tacoma 2nd gen, the engine bay of the 3rd gen looks very intimadating.

 

No...

There's no realistic way you're going to get 20+ horsepower without some kind of a tune in addition to all the parts you listed. Or if by some miracle they come out with a supercharger any time soon, then maybe.

I will say (I'm sure I'll have some retractors), that if you went full aftermarket (not TRD, I said aftermarket) intake (aFe), Magnaflow or Borla muffler, AND URD or Doug Thorney Y-pipe, AND the new Down Tubes/Power Extractor Pipes, then you'll probably gain some HP on the high RPM range, but it's not going to be no 20- 30 hp gain. But you're not going to be street legal; i.e. ever pass emissions since all the cats would be removed.... if that matters where you live.

Orange Virus Tuning is currently working on some sort of ECM tune, don't know if there's any projected market date yet though. Also, Magnuson is in the process of supposedly developing a supercharger for the 3rd gen, which would be bad ass, but could be more than a year or two away, and definitely void any warranty you would have.

Food for thought....

 

Sorry bro, it's not possible to get 300 but you can get close. With both the TRD CAI and cat back exhaust you may get an additional 10-12. If you're worried about any type of warranty issues then go with TRD parts. It 100% assures you no dealer will hassle you about your warranty. There's a post about this on another thread with a picture of a dynamometer reading. Good luck.

 

Cat back exhaust won't do squat. It's the cats and headers that constrict. Not much you can do to make power without boosting

 

Days of simple bolt on power gains are gone. Even with tuning can't get much more.

Would have to get into significant mods to see/feel any decent gains.

If you want to feel better acceleration you could just regear

 

Damn... Really? No wonder kids aren't into cars like that anymore...

Thanks for the informative post. That's too bad really.

 

If Magnuson does come out with a superchargee in two years. I will be a happy man. I could use some low end torque.

 

I wouldn't focus on trying to get 300hp because the peak power on the 3.5L is at such a high rpm. I would try to do mods that increase low and mid range power. But like mentioned these newer engines don't leave much left to gain. I've seen dyno tuning pull out some ok numbers, but not sure on the 3.5L. I see you spending thousands on aftermarket parts, and not net much gain.

 

Super charger robs power to make power. Not gonna gain any low torque, not till you make boost.

 

No, what this truck needs is torque. HP is for everything but trucks.

 

Probably gain more by switching to an electric fan....
Than you would from an intake or cat back.
Food for thought, not sure what numbers the turd gen would get.

As long as the fan isn't on. A fan that pulls as much cfm as the engine driven fan, will pull a ton of amps when its running.

 

Still less drag than a fan.

 

They didn't even try an electric fan? Electricity has to come from somewhere. The famous Ford Taurus fan pulls 33amps, that's quite a bit of parasitic loss from the alternator.

Interesting video about the power loss from the other types of fans.

 

You might be looking at about 8hp loss max from a 150amp alt at full load. From what Ive read.

 

So we're all in agreement... We're all getting superchargers when they come out!

Honestly I would love a supercharger on this truck, would be bad ass, but the $5k plus it would cost, why not just get a damn tundra at that point.

 

Also tid-bit. There are no longer exhaust restrictions from the headers, as they no longer have exhaust manifolds. It's simply a flange that bolts to the head now.

The exhaust like most modern exhaust is free flowing and is definitely not the major point of power restriction.

I always suggest weight reduction. Remove all the seats and the truck bed. Regear and you'll hit 14 seconds in the 1/4 mile!

 

Why I'll agree with you on the new/stupid manifold design, I'll disagree with you in that removing all four cats would definitely increase flow by having less restriction... Now I'm not saying how much, but I know just removing the rear cats on my URD y-pipe made a difference at around 4k RPM... Can really feel it kick in around then.

Also, the slightly increased pipe diameter = more flow.

 

Come on Hot Rodding is in everyone's blood !!

Lexus 3UZE FE 400plus hp V8 swap !!




There's also the option of pulling the stock V6 and tearing it down and blue print it . items like ..

Port matching

Gasket matching

Bowl blending

Open up the ports

Lighten up the crank

Polish the exh runners

Pro Charger has a universal centrifugal supercharger kit and I've seen them on Toyota V6's that give you a 65% increase in HP

 

Another way to increase HP and torque in the low RPM range which is what everyone is striving for is to reduce rotational mass and unsprung weight. If you decrease the weight of your wheels, tires and brake rotors it will decrease the unsprung weight which increases torque to the rear wheels in the low RPM range. Adding a carbon fiber drive shaft will also increase the low end torque. The following link for a carbon fiber drive shaft is only $699. They make carbon fiber drive shafts for drag racers with up to 3000 HP so they are very strong.
