How much was the Tb?

 

hey fperra not to burst your bubble but that spot you referred to on the hypertune manifold for your stock map sensor isn't actually for the map sensor its for the temp sensor thats white and ontop of your stock manifold, in the back, i'm working on posting up all the pics of me and shoprats attempt at the install of the manifold, it'll be up shortly

alright well the admin has not given me the ability to post pics so if an admin would be willing to let me or maybe i just don't know how to yet but if anyone wants pics of the attempted install email me at altobellione@hotmail.com and i hope to have the pics up on the forum asap

I have no bubbles to bust. You are correct. I realized the follies of my way shortly after I posted the pictures. By the way, your posts would be easier to read if you used a period once in a while.

 

Hey guys, Thanks for the interest in the hypertune intake manifold....

Just like to clear up some issues you have.

Firstly, the hood clearance issue came about due to the fact that we originally designed the manifold to suit our TB. Although it has a 73mm bore, the profile of the flange is quite a bit smaller than the factory part. When we shipped the first batches to Full-race, Geoff asked us to supply some with the factory flange. It was an oversight on my part not to re check the clearance with the bigger flange.
I have spoken with Geoff about this and I am happy to supply a replacement plenum section to anyone that has the factory style flange fitted.
We may also re jig the manifolds to provide more clearance for people who would rather use a factory style TB. The reason the manifold is so tight is mainly due to the fact that we wanted to keep the runners straight, and perfectly lined up with the port angle. Also, the plenum is shaped to provide the best distribution characteristics possible in the space provided. This meant maxing out all the space we had, hence the tight fit.

Our TB does not have built in provision for the idle bypass, but the factory IACV bolts on and a hose can be run to the intake pipe before the TB. Incorporating the idle bypass in the TB would have meant fitting an idle bypass cavity inside the plenum and this would disrupt airflow. (the plenum is hydroformed sheet aluminum, not cast)

There is no provision for the factory map sensor, as the manifold was primarily designed for turbocharged applications where an aftermarket (high boost) map sensor would be fitted. We tried to get rid of as much unnecessary parts as possible. We have however provided for the factory air temp sensor and added extra ports for external map sensor, BOV, boost gage etc.

The geometry of the manifold was designed in conjunction with Full-Race, with runner lengths, diameter and taper profile to suit high power turbo applications. It is also suitable for high power N/A setups, but gains are at high RPM and only recommended for a stout engine combination.

The plenum entry/73mm i/d TB size is provided for maximum flow on turbo setups and provides full flow capacity of a 3" intake/intercooler pipe for vehicles so equipped. The F20C is capable of huge flow and we felt it was necessary to step up from the 70mm O/D for this reason. The 73mm is certainly not too big, and for max power we even run our 85mm i/d TB on some of our EVO/4G63 manifolds this is only recommended for racing use though, and would not be suitable for a real drivers car like the S2K

I hope this has sorted out any issues you have.

Mark.

 

i just built my own manifold and i forgot to weld a flange for the IACV plus i lost it cleaning up the garage lol. now the problem is will the car run without it? how is it gonna idle?

 

You will be able to get it to idle fine using the throttle stop screw, but you will have difficulty with the cold start and when you turn on the AC.

I have to say, I do prefer the Hypertune too but you can't beat DIY. I've been doing this stuff for a long time now, and I doubt my first manifold was that good

 

thanks man, i just did it because it cost me $375 to make it and i had plenty of time since i was putting a new turbo kit. i have it installed already and cleaned up and it looks really nice. but anyway i just found my IACV so i made a flange for it, and i gonna use a vaccum hose from the IACV to the charge pipe before the throttle body and back into the manifold and it should work fine right?

 

i also had problems closing my hood but i grinded the throttle body plate a little bit and it closes fine now, that's what sucks about DIY stuff, alot of things go wrong. but it's all good now

 

Yes, that's exactly what we do on our manifold. Just make sure you plumb it correctly:

The port closest to the water pipes (on the IACV) goes to the manifold & the other port goes to the charge pipe before the TB.

Shame you're so far away or i'd give you one of our IACV adapters. It would make the job easier for you.

How cold does it get there? we get rid of the water lines to the IACV to clean things up a bit. It is only heated by water for sub zero ( deg C I mean ) circumstances. The water has nothing to do with the cold start.

Oh, and things sometimes go wrong with the production stuff too.....

Did you weld it yourself? Looks quite good.
