4.6 2V Tork Tech members

If there are any members here still active with Tork Tech setups I was hoping to get a few questions answered.

-What pulley combinations (upper and lower) give around 9-12PSI of boost?

-Is a ported Eaton worth it? I've heard all kinds of speculation around porting M112s


Any input is welcome,

Thanks!

My car makes 400/431 with the normal 7” Tork Tech lower pulley and a 3.1 upper pulley, unported Eaton and has stock exhaust manifolds. The car makes 11 pounds of boost, is tuned very conservatively with an 11.6 AFR and only 13 degrees of timing. There is a whole lot more left in it.

A ported blower is something I would do once the bottom end is built. Since an unported blower is more than enough to kill a stock 2v rotating assembly I just stayed with a “stock” one. Although a ported blower does help keep IAT’s down, so if you find a good deal on one used it’s not a bad idea.

I have had the setup on my car since 2012, so if you have any more questions just ask.

That's impressive, and I believe I have watched your YouTube videos. The setup you have seems to work very well, and I think I will do a similar build and use the same pulley combo. I'd want to stay in that boost range because I as well have a stock long block and don't want to risk catastrophic failure.

Currently I am running a Vortech V2 but I don't like the lack of low end RPM power. I hit a max of about 9PSI but anything below 3000RPM the car is pretty boring. A friend of mine is selling a bunch of parts including an Eaton M112 but he tells me it was previously ported. I just don't want to have an over boosted stock block, so once I get the project rolling I will use the same pulleys and if I have too I'll change the upper to a larger size. I didn't want to start off shooting in the dark for sizes.

Lastly, any tips or heads up for the Tork Tech install? I am a heavy duty diesel mechanic by trade and don't mind doing a bit of fab work.

Thanks!!

That's awesome man! It still seems like there is limited information floating around online about these kits, when they absolutely work!

I can't blame you one bit for wanting to jump ship to a positive displacement blower. I debated long and hard when I first was deciding which way to go and I'm so glad I went with the Tork Tech kit. At 2500 rmps its making 350+ ft lbs, by 2800 rpms my car is almost at 400 ft lbs of torque to the tires. Usually if we're going to race someone or do a pull I don't get into it until 3k rpms anyways. With some sticky tires and sticking it all down right away its a fun car to drive!

I don't think you'll have any issue with the blower being ported, typically you lose a pound or two of boost with them being ported anyways so if anything the tuner will just be able to dial back timing to not make to much power and keep it at a safe level. Really it will be more efficient with a ported blower on it, so I wouldn't be concerned with that one bit. If you had to you could always dial it back to the 3.4 pulley. I would 100% recommend getting the billetflow quick change hub for easy pulley swaps.

As far as tips for installing it there's nothing to it really. I put the blower on when I was 21, at that time it was the most in depth install of anything I had ever done. I started the project with very little mechanical knowledge. Now I can rip it apart in no time, so you wont have any issues with the install at all. The only thing you really have to do is grind down the front portion of the block for the bottom intercooler fitting to go into the intercooler. Other than that it's just nuts and bolts and pretty straight forward!

Awesome, everything you have told me so far sounds like I won't regret the change to positive displacement and also sounds it's exactly what I should of gone with in the first place.
I have someone supposedly coming to look at my current Vortech kit (locally) and hope they buy it. Otherwise I will post it up on a few forums and hope I get a quick sale. Then I will start collecting the necessary parts for the Tork Tech build.

I don't plan to beat any records or make my car a track queen. I just want to have some good fun on the street and the odd trip to the track here and there. My last performance car had a ton of low end power which I feel is more fun in my own preference/opinion.

Awesome man! Yeah the low end torque makes for great street car fun! Hopefully you can get the vortech sold and started!

Anyone know if the Tork Tech will fit under a stock hood? I have a 99 Saleen with the heat extractor hood. I bought an eaton but I can't get an answer on wether it will clear or not. Saleen used a smaller m90 on the factory cars and a lower intake that let the blower sit lower. This N/A is running me crazy! I like my original hood too much to replace it.

When I talked to tork tech years ago they claimed the setup will fit under any hood that is not the stock GT hood on the 99 to 04 cars.

Picked up this for my project yesterday!




P.S. Anyone want a Vortech kit

Ik this is a old thread but I also just purchased a tork tech kit and I'm looking for parts to complete

Hey im also a tork tech member ported eaton blower stage 2 cams 7" lower pulley 2.9 upper pulley built bottom end dont kno the hp local dyno shop close down no aditional timing walbro 255lph fuel pump 60 lbs injectors my a/f ratio reads between 16 to 18 which is lean so i dont drive it just start up every now and then tried to send a datalog to vmp but they said they cant read the datalog so i just dont drive it if anyone have any advice on me running lean or sending a proper datalog please help

@rbpf3379 When is it reading 16-18? Mine sits at 16-18 at idle and when I get off the gas after a pull and let it rev down on it's own, which is normal. Has the car been tuned at all? Or just the tork tech starter tune?

It sits on 16-18 on idle and moves on a normal cruse but was to afraid to try WOT

On the starter tune i was reading 11-14 when i got a remote tune it went straight to 18 and stayed as i got the tune upgraded it started to move up and down on idle from 13 to18 it wouldnt sit one place or stay constant i added cams to my car and i got the tune upgraded and it started to move from 16 to 18

I'd highly recommend getting a custom dyno tune by a solid shop that has a lot positive experience with blown modulars and terminators in particular. As soon as I go on the throttle, a/f drops to 12 or lower, and when I'm pedal to metal it's pretty much 10. If you just your remote tunes, you could rev to 3 grand and watch the a/f. If it's a decent forced induction tune, going on the gas and building boost should put the a/f around 12.

Here in the bahamas we dont have such a dyno shop

Well if you email tune is from a legit company and took all aspects of your setup into account, give it some gas and watch the a/f.

Give it a good rev then... if they said you can rev to redline and build full boost with that tune and be safe, then go and do it. What's your hesitation? Do you not trust VMP?
