3.4L supercharger

Also location plays a role, closer to sea level and/or in a hot climate more likely to ping

 

Correct. But on these trucks it’s a timing issue. Not a actual detonation issue. If it was actually detonating we’d probably see more failures.

 

Yeah, so it's going to suck building the truck in Colorado above 5000 ft and then taking trips down to sea level only to find out I'll be spending time tuning, changing pulleys, removing the belt ...

 

that makes me feel a little better about it, it's true I haven't really read of many stories of boosted failures on here over the years. One comes to mind but I remember the guy saying he constantly floored it around town even though it pinged like crazy, one day on the highway he went to pass a semi and floored it despite pinging and threw a rod. Can't remember the guy's username but its on TW somewhere

 

So as I drove I’m trying different things. I’m cruising at 0 PSi and slowly upping the gas and it will got to 2 PSI and AFR goes to 13.8 from 14.8 and it’s sound good. If I push the gas a little more, it hits 12. It seems to be cooperating with me.

 

@BlackSportD
I noticed that most people with a auto transmission don’t go past a 2.2 pulley

Thoughts?

Awesome “reverse mod” man!

 

you’re really stuck on this pulley size thing. I hope you realize it’s possible to make more power with a bigger* pulley. The higher the boost the more HP it takes to drive the blower. Google how much HP it takes to drive a blower, you might be surprised.

At the end of the day no matter what you do to the TRD S/C and the 190hp 5vz with no ECU tune available it will always be a sub 300hp truck.

EDIT: Larger not smaller.

 

Maybe because it makes the S/C just that much more itchy to boost sooner? I donno. I can imagine with more air to recerc plus that transition area for the bypass = a slightly more aggressive mid vaccum region for the bypass transition and the auto already loooves holding that tall gear and creating high load sub 2k rpm boost.

This is me armchair tuning but I've read the trd blower is on the small side and going smaller pulley to make more boost is not a linear gain relationship. The s/c efficiency curve (or lack there of) is a more exponential one, so going smaller causes so much more heat you are fighting some serious diminishing returns.

Everyone's S/C and VE is different, some people have the trd sc with no EMS and no problems, my 5vz is so pingy I expect on a cam shim/s and/or cylinder inspection that I have something seriously wrong so I can't imagine going to a smaller pulley. Or maybe my exhaust has an instruction or the cat is partially melted. In fact I might go back to stock or even underdrive.

 

Who wants to play the lottery and see if this CHEAP supercharger from Singapore shows up?
$1900!

Probably not your cats. You would be getting other symptoms as well.

it’s got to be the shitty transmission tune. Really banking on @OVTune here. I might just sell it all and get something else.

 

I am a little I guess

I understand I am never going to get above 300hp...but I would like to get to 300 if I can.

 

If you go twin charged you'll want the bigger pulley anyway, super easy to get boost creep and runaway with the SC pushing more than it has to. This SC is so puny anyway it'll just become a heat pump more than an air pump the farther you boost

 

reading up on this twin charged thing Ive decided it wouldn’t be worth it at all. You’d just have a $3000 intake manifold you’d have to fuck with too much.

 

Yeah, single turbo is the way to go really. The SC just has the advantage of being an easy bolt on. That's about it.

 

I hear you man. The thing is... you take a truck like ours, which is normally in the slow lane and then we supercharge it. Now we are in the fast lane with a stock pulley. No one thinks much of it. Then the BMW behind us tries to go around us up the hill on the freeway. You say F that-- go into boost. the BMW goes back behind you and drives behind wondering "WTF". What I'm trying to say is we have the element of surprise whenever we want. Now let's say the Raptor knows you're supercharged, he'll floor it too and kick our ass (Only John can take a Raptor). What I'm saying is It's a hell of a lot fun just to be supercharged and running good.

 

LMAO..... these Tacoma are still slow, even with the charger... sorry to burst your bubble about a fast supercharged Tacoma..

 

Its all relative It's fast or slow compared to what? a race car? Yes it's slower than a corvette or mustang. But it's faster stock than a 3rd gen Tacoma. What are you saying man?

 

That's the cool thing about these trucks. They're geared well, especially if they're a manual. Sure a 1996 Ford F250 V8 has more HP and TQ but I can run circles around one in my 96 4 banger taco or my 96 v6 taco

 

Im saying they're slow in general. As you mention, BMW saying WTF when trying to pass you up, are you comparing your truck to a E30?

 

I'm with ya. Anything faster let's say a Vette or whatever cannot be off-roaded or driven in weather. S/C tacoma doesn't have that problem. A Raptor is fast but $$$$. Not to mention size and parking.
