Twin Turbo - MAF upgrade?

[07stalker]

The project: 07' 4.6l front mount twin turbo's.

Already have: Twin GT35 turbo kits, IC with twin 2.5 intlet,3" outlet, IC piping,BOV, 3:73 installed.

Fuel upgrade to purchase: Ford dual fuel pump kit and 47lb injectors from American Muscle.

Tune and dyno will be done @ realspeed. (date to be scheduled for April, depending on how well the manifold build goes!)

Status : Building front mounted manifolds, moving relay box back to battery location. More to come as I get deeper into the build.

Question: Do I need to get a different MAF sensor for this setup or is it adaptable with the tuning?

Anybody install the THP twin turbo kit???

The stock maf will peg depending on the flow created by yoir setup. You could buy a larger maf meter or use a diablo mafia. The mafia, I have one sitting here, is cheaper and just plugs in between your maf and the car.

Both need to be tuned. I am not familiar with that turbo kit. Best of luck.

I quickly spoke (email) to Dan @ realspeed. Depending on how the manifold build goes, I am looking at tuning mid-end of April.
When I get to the the intake pipe, Dan is going to let me know where to put the MAF.
Not sure yet on boost yet. The goal the year is a couple pulls @500 rwhp then detune

Sounds like an awesome project!

Other than fabing up the manifolds and CAREFULLY relocating the relay box, I'm feeling like everything esle is pretty straight foward. Hope I am right!!
I only found 2 TT kits, mounted under the hood, for my ride. I am inspired by the THP (turbo horsepower) twin front mount kit.
Have any of you installed a TT set in your ride? Any "watch outs"?

Check into it but i believe all the turbo guys prefer a blow thru MAF unit. Why such small injectors? You should have 80's minimum. They will be perfect. Your tune will tell the injectors how much to spit so its better to have too bigrather then not enough. Keep us posted on the build and good luck!

My Ignorance on the injectors. Most of the s/c kits I was looking at and different forums, people were swapping in 39lb. I was looking at the fuel pump upgrade on the American Muscle web site and some 47lb were being advertised. If I can go big and the tune makes them work properly, I am going big! One of my deciding factors of going turbo vs s/c is flexablity. Once get something forged in there, I can take these little turbo's and blow my F250 SD

39's are fine up to about 490-500. I run 60's and going to be pushing 650+.

Turbo and blow through is a great idea, no need for 80's with a stock block. The block is only "safe" for about 500, but some have let go at as little as 400.

Plan the build. Do research, find out what are the best applications for your goals, no reason to do it twice cause of an oversight.

Do you want a blower or tubo, a lot has to be changed to switch over between the 2.

I wasn't aware he block was only good for 500hp. If that is the case I would go with frpp 42's and a vortec sc. Twin turbo is a lot of money and work for only 500rwhp. TT seems a bit overkill. Def set a long term goal and go from there.

 

[07stalker]

Sorry for the relating to a s/c. I am going twin turbo. The power goals are established, the fuel upgrade is planned, the tuning/dyno shop is established, installation is underway.
I'll research the suggested flow thru style MAF.
Thanks for the help!

 

[07stalker]

Yes, the long term goal is to forge everything or drop in 5.4 and turn up the boost. That is of course the long term.
Short term, this spring, one qtr mile with even just 450rwhp against my brother in law's 60K Challenger SRT8, 392

Here's my twin turbo build. I went with a BA 5000 MAF sensor... Do not go with such small injectors.

 

[07stalker]

Thanks for the heads up. Took a little while to reply as I just finished reading all 9 pages of your build! This is going to help alot!
I actually think I may have met and seen your ride last year. Did you go to Untouchables car show in Germantown last summer by chance? What rwhp are you currently running without hurting the motor? Did you detune after the 500 rwhp pull?

Yea that was me at untouchables and nope haven't detuned her at all, if anything the boost started to creep more. I would say she's been from 500-550 for 17,000 miles maybe more. And those are hard miles. It's all a matter of luck, I have known guys to blow motors at much less. I was ready to blow her up the first year I put it together... Just be ready. Oh and good luck with the transmission !!!

Thought it was after seeing your build thread. I had my orange 88 vert at that show. I actually sold it that day!
Did your tranny let go? Any problem with the stock clutch?

Thats crazy you sold it that day, that carshow was fun.
I wrecked my stock clutch just pushing 350hp with cams. Upgraded to a Ram HD power grip, then blew my transmission about 7,000 miles into the twin turbo setup. I built the trans, upgraded to a 28 spline input shaft and a RAM 9.5 inch dual disc clutch. Then I stripped on of the hubs on the clutch discs in the transmission had to pull my transmission for the 10th time and get it rehubbed.. Just be ready to spend lots of money lol.

Thanks for the heads up. Not a bad show. My third year and it gets bigger every year. I'll be babying her for a little when I'm done. Really just need the rwhp one day at the valley (with my bro in law's 392 srt 8 following behind)
