Question for those with TRD blower expereince...

Thinking of getting one. For those who have, did you also install Doug Thorley LT's? Did you dyno before/after the LT's? Butt dyno? 4.0 engine.

I have an 06 with DTLT'S on it currently and am considering swapping them over to the 2010 Tacoma before I sell the 06 and am curious what gains some have seen with the LT's on an SC Tacoma vs stock exhaust manifolds. Did you lose boost and have to go with a smaller pulley after the LT's? Pro's/Cons?

Having done it once, I'm not looking forward to the swap (which will be like doing 2 vehicles) unless the gains make it worth the trouble. I'd appreciate any feedback on this. Thanks!

 

I think trd recommends using the stock manifolds. I know guys are running the thorley long tubes and a trd blower, but they probably aren’t using the stock toyota ecu flash either.

 

When running the TRD s/c(or any FORCED INDUCTION for that matter), letting the engine breathe as much as possible is one important aspect to getting the most out of the supercharger.

On roots type blowers, your peak boost is determined by the pulley. You could run open headers and still hit 5-6psi on the factory pulley(where TRD says it peaks at). You don't lose boost pressure by opening up the exhaust.

With that said, it would only make sense to transfer the headers over to the newer truck. With the right accompanying mods, there are TONS of gains to be had going with DTLT's on a TRD s/c.

Now, the only thing I will recommend is to upgrade the fuel pump ASAP. If you plan on running an aftermarket intake(which would only make sense) with the DTLT's on top of the TRD s/c, your weak point will be the factory fuel pump. Trust me, and others will tell you the same, it is CHEAP insurance making sure you don't run lean from factory pump.

It would benefit you to also get an air/fuel ratio gauge for that added piece of mind just so you know how the motor is running.

The factory TRD reflash can and WILL accommodate a 2.85 pulley just fine---again, as long as you upgrade the fuel pump. Check my build for more info.

Are there guys running factory fuel pump, no boost gauge, no afr gauge with a TRD s/c? Certainly....but when you factor in the cost of a new motor vs. the cost of an upgraded fuel pump, a boost gauge, and an afr gauge you'll see it only makes sense to do it right the first time.

 

Quality post!

I heard if the DTLT will void warranty if installed.

 

It won't void any warranty, also I'd get a turbo over a SC.

 

Anything that tampers with/modifies/deletes factory emissions equipment components(that isn't made by the manufacturer like "TRD") will void your powertrain warranty.....but the burden is more on the dealership to prove the parts cause some sort of failure in the event of a warrant claim. Some dealerships are more forgiving than others and will gladly turn the other cheek to 'grease the squeaky wheel' and warrant anything other the sun while some dealerships take no bs.

While a turbo setup takes no power(other than exhaust gas) from the engine to make power....it is not practical for most owners, Tacoma ones at that, to go out and have all the tooling, fabrication, and most importantly tuning done.

Turn-key conversion is where the TRD SC shines. You buy the kit, drive into the dealer to have it slapped on, and pick it up and drive it. No tuning needed. It's not the most powerful, but it's a lot more than what you get from the showroom floor.

 

Matt-what fuel pump have you found to work well?

I have several experiences with supercharging. I've had a 1st gen Tacoma and 4runner with blowers as well as an 07 Chevy with the 6.0. With headers and a good catback On the chevy I saw my boost drop from 5.5lbs to 4. I had to drop 3 pulley sizes to get to 6lbs, hence my question on what exhaust and headers do with the TRD sc in regards to boost.

I also had an 01 C3 pickup with AWD that I put a whipple sc on and after significant mods to make it all work would run low 13's. Having more money then sense at the time I let my mech talk me into turbo charging the truck. The result was low 12's, horrible fuel economy, heating up everything under the hood and barely able to tow itself up an incline in hot weather without overheating the engine and trans, let alone being able to tow any kind of trailer anymore. So, yeah if you want a dragstrip queen and that's it...turbo. If you'd like a truck that gets down the road ok, still gets decent mpg's and will still tow something behind it, then for my money, turbos are not even a consideration.
And don't bring up Fords current tow mobile using turbos unless you've done some research and see how many guys are trading em in for the NA version due to the reasons I just mentioned.

 

I've got the Walbro 255 in my truck. URD makes an all inclusive kit which also converts the fuel filter to an external(MUCH CHEAPER & EASIER TO REPLACE) type: http://urdusa.com/Fuel-Upgrades-Fue...uel-Pump/Filter-Upgrade-Kit/product_info.html

I have heard of other s/c applications dropping boost on exhaust changes as you've experienced, but the Tacoma is not one of them. TRD rates their s/c kit to peak @ 5-6psi. With my DTLT's and full 3" custom turndown exhaust I still hit 5-5.5psi. Changing to the 2.85 pulley upped my peak to 7psi.

Turbochargers in (working) pickup applications isn't practical, unless it came from the factory that way(ie: EcoBoost) or it's a diesel. Turbocharged setups can be much more temperamental, and as you stated, generate A LOT more heat.....I would know as my other 2 vehicles are turbocharged.

 

I still think you could do a little R&D on XRU, get a garret turbo setup and have low end power, where as the S/C will only give any worth while gains after 3k rpms, and suck your mpgs down while doing it. Sure you read all the time about people getting mixed mpgs, some good some not so good, but the cost vs gain is too marginal.

 

AFTER 3000 rpms? OKay I'm going to shoot from the hip here and assume you haven't lived day to day with a TRD s/c?

I have significantly more power AT 1 PSI with the supercharger than I ever did without it. I can muster up hills with the boost gauge still at "0" psi and still do it with much less effort than without the s/c. Honestly, you're missing the point......and to add if you read he is going to a 2010 Tacoma-----URD UCON & APR X-1 only covers up to 2008 Tacoma ECM's so this discussion on research is moot since even now EXTRA work is needed for a custom turbo setup to run properly.

Cost vs gain is opinion. Some people can justify the $3900 for the TRD S/C being that it's completely plug and play, offers a healthy amount of power throughout the powerband, and no research needs to be done----you have to consider all the people who don't frequent message boards to do said research.

To put it in perspective:
URD UCON(which is back ordered at the moment): $1800
APR X-1: $1500

That's HALF the cost of a TRD s/c kit already-------and you still haven't gotten injectors, fuel pump, fabrication materials, fabrication labor, tuning labor(to get it to achieve power better than an s/c), set up labor, cost of brand new turbocharger etc....if it was that much better, tons more people would be taking the time to do this but the reality is it's just not worth the trouble to most.

 

Ran one day to day on my 11, not sure what URD has to do with me saying garret turbo setup since URD blowers are essentially a S/C and not turbo setups & I'm only stating my own opinion.

 

Uh it has everything to do with you saying "Garrett"....how does one expect to run a custom GARRETT turbo setup on a factory computer? Of course aftermarket engine management like an APR X-1 or URD UCON. I had zero references to URD blowers in my last post unless you thought a UCON was a blower?

Your opinion is fine, as I will state mine. But misinformation about things especially with performance, people should tread lightly on if they really don't have first hand knowledge(the monetary and labor dedication needed to get a turbocharger to work well on 1GRFE Tacomas) as it will only start the snowball.

 

There are plenty of people on XRU who do the R&D, and sell their kits to upgrade to something else. I gave no misinformation, I said what I think would be better, what anyone does with that info is their business. Get your panties out of a wad.

 

What does a "kit" have to do with an engine management? Does someone have plug & play engine management worked out for 2009+ 1GRFE Tacomas? How much more cut and dry do I have to be THERE IS NO PLUG & PLAY ENGINE MANAGEMENT FOR 2009+ TACOMAS. So my original point stands...a turbo setup wouldn't even be possible on the OP's 2010----THAT is the misinformation you posted.

Grow up and stop generalizing, dick. I came with facts and you come with bench opinions. He stated 2010 Tacoma. Fact.

Move along...

 

Op never mentioned anything about engine management, you did. Aaaand I didn't see where he mentioned a turbo setup is out of the question so I guess I will move along, nice mall crawler you got though.

 

I really am talking to a wall.

It behooves you to research on the components needed to run a turbo on XRU yourself, Garrett Boy.

The most important being THE BRAINS. Guess what? The factory computer(4.0 1GRFE) cannot handle compensating for fuel, timing, and boost an aftermarket turbo set up needs. So what do Xrunner guys use? APR X-1's or URD UCON's to tune them....hmm and guess what again: they don't make those for any Tacomas after 2008. Now for the umpteenth time, how do you suggest he goes about that on his 2010?

No the OP didn't say anything about ENGINE MANAGEMENT, but.....

you're the one who spat off "Garrett" like it was a realistic option, showing me you have no clue wtf you're talking about. Your continued skirt around my question on engine management needed for his 2010 Tacoma to run your coveted "Garrett" turbo solution further solidifies once again, you're just saying turbo because TURBO TURBO TURBO...with no actual solutions much less anything to add factually to your suggestion.

That said, I will leave you alone...free to go suggest turbo to many thousands of Tacoma owners on these forums using bench generalizations("tons of people have...") and opinions to prove why they're so lovely.

Thanks, I love my mall crawler.

 

If you didn't see where I said turbo was out of the question, you certainly didn't read very carefully.

There is NO way I would EVER do a turbo on a truck again unless it was simply to run it down the qtr mile, which I've done and won't do again.

For my $ it's either NA or sc for a tow vehicle or a diesel for big jobs.

 

Not directed at OP but more towards still will...

http://www.tacomaworld.com/forum/2n...70-custom-front-mount-turbo-2nd-gen-taco.html

This utilizes a stand alone Engine Management system that is wired in NOT plug and play. On a 2010... With turbo and 395HP

 

Yup they are out there.

Seen that build and it truly is a one-off custom done correctly. Nice truck!

Proves my point, no plug & play em solution for 09+ which alone is enough to make or break someone's desire to go turbo. I commend the tuners who know how to wire in standalones. Skill and balls!

 

There's also unichip that has a plug n play for the 09+,but remember its a few hundred for the standalone plus you'll need a custom tune for your fabricated or bolt on kit. Or...$125 at the dealer to reflash your ecu for the trd sc.

I agree with still will, turbo isn't practical or economical TODAY for the common daily driver.
