[?] '18 Intake Manifold on '15-'17

[Cream Puff]

And here is something I saw posted on FB.. looks like the connector for the 2018, also shows 3 wire.

Sorry for the multiple posts, I just want the information to be separate from my speculation.

so what I see here is the 2015 uses connector part number WPT1261 and the following wiring colors.

While the 2018 uses connector number WPT1492 and the same wiring colors

looks like it might be simple... thoughts?

I have been contemplating this mod for a couple weeks because of the low cost versus the GT350 IM so this thread is very interesting to me.

Here are my thoughts and speculations regarding your posts. It looks like the imrc controller and valves are the same part numbers for both vehicles. It seems the only difference is the connector part number. Could the connectors be interchangeable? I’m thinking/wondering that I could just not use one of the controllers and valves and the rest be plug and play.

Can someone who has done this mod confirm? Or is it just a waste of time and I should consider locking them out? Would there be any real world benefit (fuel economy, drivability) to having them operational?

I was talking to one of the Steeda employees at the track yesterday and they said they were bolting an 18 intake on one of their track cars for testing this coming week. I'm curious also to know how it performs.

 

[S550Smoke]

you don't know if it was their yellow t1 car do you?

 

[GT0038]

No I do not know, he did not go into detail on which car they were going to use.

 

[MasterCylinder]

This would all be resolved if someone would just do a variable runner length intake like Porsche. >_<

 

[BMill705]

Does anyone know if the gt350 throttle body will bolt up to the 18 manifold? If not will the same adapter from the 15-17 ones work.

The stock 15 Tb fits on the 18 manifold . The manifold inlet on the 18 is still 80mm and the gt350 is 87mm. Mine should be here the end of the week I hope !

Supposedly the 2019 Bullitt uses the GT350 other than cost its GT350 is still 2nd best option behind if you are willing to make a CJ fit.

Yeha you just buy the 2 pigtails and repin it and should be good to go. That’s what the people on the Facebook forums are doing and seems to be working

 

[yohoeimmattbro]

Sub. Will be buying my 18 manifold this week and waiting until everybody has the installation figured out

 

[keiths2kgt]

Good thread I would love to do this if it pans out

The IMRC valves do not really come into play at WOT. In the RPM range we tested, the valves would normally be open anyway. We were also testing other manifolds that do not have the IMRC valves hence why we disabled them on these manifolds.

IMRCs aren't doing anything at 3,100rpm at WOT???

Would have been nice to see the pulls start at 2,000RPM.

What we really need to see is a Power Pack 3 GT350IM vs a tuned 2018GTIM with IMRCs enabled. That would be a better comparison like the motoiq article showing PP2 vs PP3. Using the same tune across all 4 manifolds with IMRC disabled keeps things constant, but it's also abstract when the better flowing manifolds would gain more in the bottom and mid range from IMRCs than stock or the F150 manifold.

How are you liking your PP3 setup after you've had it a while?
