Just wondering if any one has created one and the results. I saw that mazworx was manufacturing one.

With the mention of the n1 manifold not being of great benefit i was wondering if any custom ones have.

i built 5 or six about 2 years ago, there were dyno sheets vs stock and vs n1. not sure what happened to them

im trying to see if i can mate the pulsar itb's with the vvl intake runners. i feel that should produce some good power scince im goin all motor. :biggthump

i'm now running a jenvey itb setup (just search "custom intake manifold")

GTiR ITB's + VVL head? If so, its been tried before

well on the de the stock manifold vs the custom made a big difference...and i can see that the runners are fairly different, so estimating that its going to make an even bigger difference on a ve, plus the head flows alot better...

how are you liking them, good power gains over your custom manifolds? Worth the money in your opinion. What standalone are you running?
Cheers

had a calum real time but i, switching to an aem. worth the money?? thats up to you, it cost me $2600 for the setup and i had to get my own flange from the head to the bodies made. so $3000 all said and done plus top feed injectors and dyno time, i dunno. About a %15 gain over my manifolds (i've been promised by jenvey). i haven't dynoed this setup yet so i don't have accual numbers

Watching your outcome with much interest.

Be looking forward to your results, best of luck.

You didn't consider running the Calum in Alpha-N mode? I know its crude but it is capable of doing the job

i've had to run with no nock sensor with the calum for the most part in the past, so i can fine tune this with an aem (12:1 going to be running it on 94-94 octane pump gas). i like the built in wide band that can seft tune if things are going wonkey on me. i'm a month or two out from the dyno but just brakeing the motor in on the dyno with one of my manifolds i'm looking to be well over 250whp (hopeing to brake 265 @9000rpm eventually)

There's a few rare O2 Induction ve units around.

Here is the intake which will be going on...and yes its been designed on a flow bench, i dont know what the numbers are but here are some dyno graphs of before and after the intake was installed - note it was not tuned...and yes this was when it was on the de.

I'm going ITB's on my built motor, 15% is a big promise but If it delivers then hell yeah I'd say $3k is worth it. Please keep us filled in on how you get on
Did Jenvey spec the intake length for you , based on your motor?

how are you getting on with that intake brett, its looks well made for sure.

i think that monifold is for a turbo high port de not a ve

Its definitely not a VE Lower half The injector bosses are way different..... and now that you've pointed it out the Runner length does look pretty short for NA use.

I'd be investigating a bit more brett and finding out if they actually make one for a NA ve as even if the can make one for VE the runners would want to be a bit longer IMO
