The new RS TB hasnt been tested much on the NA MK3 , Dont know what its going to do yet

I have had 2 People try TB from other Vehicles that were plug and play and they wouldnt work

To the guys that bought the new Intake manifold , I would start with just the manifold , then do the TB , then the 3 inch MAF till more testing is done

Tom

The ST has used an NA TB and the 63mm TB, so plug n play should be simple, but yes till installed not totally verified

Tom, would that help with the datalog ?
I may have to put the intake manifold and 3inch intake on one go as thats the only intake pipe I would have.
I can do the throttle body and maf on seperate datalogs.
The 180 degree thermostat wouldn't mess all that up would it

I'm a glutton and just ordered it. Gonna install that, the intake manifold, 180 thermostat, 3inch intake and if the MAF tube works a 3inch Maf tube.
All at the same time. Hopefully it works out. if not gonna sell it on eBay?

Every new component or changed component is a variable to consider if something should go wrong - More variables mean less certainty which means more time consuming troubleshooting.
Best to do one mod at a time, assess any differences and then continue on.

But however you decide to go about doing it, good luck to you! [wrenchin]

Does anyone know the diameter of the k&n intake ?

I'm wondering if we could talk Tom into making those 3in intakes he made awhile back. they dont have a heat shield or anything like that so they might be easier to position with the new throttle body placement on the TTR intake manifold. The intake he made has a 3in maf built in too. He also tested a 67mm TB he made himself. he said it showed no gains when he dyno'd it but maybe it would in combo with the TTR manifold and 3in intake.

last couple pages of that talk about the 67mm TB he made.

Let's try and stay on topic guys. This is for talking about the 68mm 3.7l TB

What more is there to say about the 3.7 V6 TB ? Its been tried it doesnt work as a bolton and go TB

There are those of us who are curious enough about this option to see what it takes to make it work. That's what this thread was originally aimed at.

I would be open to anyone that has the new intake , RS TB and my intake pipe to offer my Dynojet dyno for testing to see what each part does , There would be no dyno time charge as long as you have my tune already

That's awesome Tom. I wish I lived on your side of the country!

It more then likely can be made to work , Are you willing to cover the R&D time to get to that point , If you are just let me know and we can get working on it today

At $75.00 an Hour its going to get very expensive very fast , I guarantee you way more then the BBK cost

MasterBuggy and I are taking this on as right now we suspect that it can be made to work without modifying the base tune (obviously, it won't perform as well, but that's a different end goal) and right now we're doing it on our own time as we have time.

1turbofocus · Mar 2, 2017

I think its great , problem is the changes that need to be made will all be in the software that runs the drive by wire PCM , I would be very careful doing what your doing can cause the throttle to go wide open for no reason if it gets the wring signal among other things

Might want to talk to the guy in here that had it on for a bit , he might be able to shed some light

Good luck I hope you get it working

I would be that guy lol

Let me clarify a little bit about what tom is getting at. After numerous revisions, Tom managed to get it to start up and idle some what normal. After a few minutes, however, the rpms would begin to vary. Little by little the rpms would go up and down more and more until it got too low and stalled. After this we decided to abandon the idea in favor of boring out oem focus throttle bodies.

I know that you and Tom put a lot of hard work and time into testing this before, but my only question is: Did you have the circuit diagrams of both TBs to know that pins 3 & 6 needed to be flipped?
The significance of those two pins is massive, and if you didn't know then what we know now, that could be precisely what allows it to work this time.

I had the mustang pin out yes but we were waiting on Tom's focus manual to come in so we could gave the other half of the puzzle. It might work but I have my reservations having seen this sort of thing on the speed3 forums. Everyone wants a biggger tbody but thos dbw stuff is a PITA. A slight voltage difference in either the tbody or even the pedal will mean it won't work.

MisterBuggy · Mar 2, 2017

All the voltage signals on both cars are 5v, so there shouldn't be any problem. I understand having reservations, but there's a good amount of information suggesting it's worth a shot.

Even if it ends up working, the BBK TB will admittedly still be very appealing to me personally, because i like the fact that it retains the OEM mounting holes.
Nonetheless, pursuing various paths simultaneously is a more efficient way of finding the solution that we're all here to discuss; a larger tb.

the BBK one is $500 though. that's a lot. especially because we haven't actually seen any proven WHP gain from a TB upgrade.

FFhb13 · Mar 2, 2017

^^^$50 vrs $500....I would never pay $500 for a larger TB...I've paid around $250 for a bored out TB after a core charge to send them your stocker.
