Bought a supercharger, now what?

Hey guys let me give you some background. I'm a bit of a fabricator and I'm building Tony's 99 Access cab Tacoma. I'm haven't dealt with superchargers yet but seams like a simple enough concept. I would just like to know all the other accessories will we need? I'm not looking to run the 1/4 mile just more HP for ripping through whoop sections and sand dunes.

This what I have picked up so far


You can't see the new tensioner and belt but its in there. What kind of fuel mods will we need the current engine has 160K is it over the hill should we have it gone through?

I got everything through this guy

I can just call a shop get this info but I want it from my fellow non bias Tacoma owners that aren't trying to sell me stuff

 

Guy to really talk to is Jason. He will know all the OEM parts that you should have.

Fuel wise, I'd get the URD 7th injector kit and maybe throw on a 2.2 or 2.1" pulley for more boost

 

If i could do it again I would run the supercharger with stock pulley and get a wideband 02 sensor and see how it does first, then either water/meth inj. or URD 7th kit.

 

Swap mech fan for e fan. Deckplate mod to airbox with high flow filter and afe mit for best results or make your own mit. 2 step colder plugs. Colder t-stat. Afr gauge. Ability to tune afr and timing. Check urd site. Tune out any knock with timing and high 11's afr with stock 2.37" pulley. Just the above should get you in the 230-240whp range and 6-7psi boost. Then if more power, headers, exhaust mods. O2 sim if cats gutted or deleted. Water/meth inj. Then to sc pulleys 2.2"(9-10psi), 2.1"(10-11psi), or smaller.....keep timing in check and afr in high 11's for safety..... Around 300 whp is the absolute most you can expect with all listed mods unless you start sprayin n2o..... fyi... I have 2.1" and 1.8" sc pulleys if ya want to buy one for what I got in them. Also have a lighter crank pulley..... all custom made stuff.....

 

Would not do a high flow air filter. Lets in too much dust and eats the rotors. Jason just spent 2k rebuilding his sc due to that

 

That had a little more to do with the masive amount of sandy salt water he sucked in it.

 

The S/C runs lean. Last thing you want is more Air IMO. URD 7th Inj is mandatory IMO. I have stock tuning on my 7th INJ as gadget said it will likely run better than messing with it. But I still run a bit lean even with 92 octane. Enjoy I love mine.

 

More air means more potential power... Regardless of mods a timing and afr tune are a must...octane has nothing to do with afr...more to do with timing... what is your definition of lean? They run strong with afrs in the low-mid 12's but to be safe and help keep knock at bay mid to high 11's is what I like... oh also be sure to hook fpr to back of sc for free 1:1 fuel psi to boost psi rise to help on the fueling end...

 

Yea more air and more potential combustion. But the stock fuel pump and ECM certainly can't keep up with the fuel delivery with the 3.4 set up. The ping is horrible. I dealt with it for several thousand miles before getting the 7th inj. As far as Tuning, like I said I keep my 7th injector at stock setup because I don't want to F anything up. Most people with the 3.4 S/C are running stock air boxes.

 

Ya upgraded fuel pump or something like kenne bell Boost-A-Pump is a must..I ran mine both ways...tune is best left alone if not comfortable with tuning and gadget has tune for your setup. It is however a good idea to be able to monitor state of tune via gauges at all times just to be sure everything is working correctly... If comfortable tuning you can get more out of your setup. Most run stock box due to maf in box and ease of tuning vs maf in a different intake setup. At one time I had a 3" pipe with the maf in it hoping I would gain decent power but only had maybe 5hp gain and tuning the maf in the 3" tube was much more difficult than tuning maf in oem airbox.....

 

For a desert truck i would suggest an UMP type filter. Is what i use and has been keeping the dirt out, regardless of the minute gain or loss.

 

can you tell me why you run the plugs two steps colder?

 

Ahhh yes Mr.Berry is in the know I forgot its not just 4wd long traveled its SC'd

water/meth?

Thanks for the list dude but I'm really looking for minimal mods just want it to work and be reliable

Ouch

Good info I'll look into the 7th injector

Yes I was considering order a UMP for my truck too

 

Did you guys click the link?

He has a tuner. Is it worth the cash?

 

now install it and the world is yours>>> start by racing every vehicle known to man, get sponsors, get rich, buy lots of things including countries, build an army, and take over the world..... whats your plan of attack?

 

So just 7th injector and call it a day. I think I'm at around 120 feet

Going to pick up a UMP too

 

Ad a tranny cooler and service to that.

 

7th injector is CRUCIAL on 1st gen SC's. Listen to Jerry, he's got it down.

ALSO don't forget the AFR gauge(even more important that boost gauge honestly). AEM UEGO or Innovate MTX-L(the one I have). I know you have experience welding bungholes lol.

 

If you do the 7th injector at the same time as the blower then don't do this. It made mine run really fat and it took me a while before I figured out what was going on.

I also had to play with the fuel part of the tuning on my 7th injector after I reversed the FPR mod. I have my AFR in the high 11's to low 12's at wot.

When I put mine on I bought the stuff I needed from trdparts4u.com.
I went ahead and changed the oil in the nose cone. You have to change the metal throttle body gasket to the paper gasket, so I did that. And I also got the install kit, which comes with some fittings, new throttle cable brackets, new vacuum line, a new long center bolt for the middle of the blower, and the one way check valve.

I attached the most up to date s/c instructions that I have. I read through it first and it helped me find out what parts I needed. I also attached the template for cutting the timing cover.

I think that covers everything lol.
