Getting the itch for some updates... any progress with the latest iteration of the manifold?

We are on version 4.0 on the manifold. It fits perfectly!!! Now we are working on new fuel rails :tup: the car should be up and running and back on the dyno this week. The heads on the vhr motor are not symmetrical which had the manifold in a not so ideal position. With a few design tweaks gtm was able to correct the way the manifold sat and now we may have the possibility to retain the stock cross member *fingers crossed*. now that the manifold is situated we are working on the reproducible fuel rails to allow you guys the chance to get this upgrade. Before we had one sized fuel rail for the right and a different size for the left. With the new manifold version gtm has simplified the design to allow the same size on both sides!!! :tup: keep your eyes and ears up for the next week or so ;)

Retaining the cross member? Symmetric fuel rails? :tup:

BTW, are you getting an engine cover? I wonder about dremeling a small section to allow easier access to the oil cap. Also, are you guys able to retain the stock oil cap? Just seeing if you are going down this path.

Also, with so much invested, have you considered an engine window of some sort like the ZR-1? A properly vented and windowed painted OEM hood (i.e., keep things clean and not too aggressive looking) would be nice.

If possible, please feed some photos of the fitted components.

:excited:

Has this beast seen 1000whp or beyond yet?

Is the v4.0 manifold the intake manifold? Is it the one shown as Sam's avatar pic? Only for FI or will NA see some benefits as well?

I don't know about Sam's avatar picture, but the manifold being referenced is the lower intake manifold that connects the upper intake plenum (visible) to the heads. This is the custom piece that will allow us to make use of the intake plenum from the VR38 motor.

Were you guys able to get it back on the dyno this week?

I ordered the Stage II last week... definitely itching for updates since this is all I'm waiting for at the moment.

I will call sam tomorrow... I have been in and out of town all last week... Due to weddings and mtn bike trips... Just got home last night from a 20+ mile mtn bike ride up in the north ga mountains that I swear wanted to kill me and my fiancé lol.

I wanna see this thing done! :)

FIANCE?! Wait...you're getting married?! And to a dude?! Bro, call me...we gotta talk! :tup:

Yeah getting married bro but not to a guy lmao... Her name is Brittany and is a former model for petite Le mans and nopi... She loves cars too!!!

Well, then spell it correctly! "Fiancee." *haha* You, sir, are the "fiance"!

Ok, mang. This is all news. So I gotta meet this lady. Give me a ring sometime. We'll meet up for dinner or something. And CONGRATS!

Congrats man :tup:

I'm sure i've missed it but have their been flow tests on the VQ35HR and VR38DETT intake manifolds? How much better does the VR38DETT manifold flow?
