i still say there dyno reads a bit high

 

i'd like to see some testing on this

 

+1.

Any update with tunning? And possible post inside the plenum pictures? thanks.

 

they need to demo this product if they make it on a complete stock DE Z. With no mods done to it as far as Cams, Exhaust work, Intake work. Then and only then will we see true gains if that. Otherwise its basically only working well with the mods they have now as i see it. NO OFFENSE!

 

VO...

 

Thread cleaned up. Stick to the topic gents. Carry on...

This is the design that i wanted to make for my Z. Its from a Toyota Corolla.

Sort of like this.

 

in case anyone was interested in the vq vs vk tb... I posted this awhile back. Has all the measurements for both.

 

IIRC, his original baseline dynos were pretty much on par with most of dyno charts found here on the forum.

Either way, try not to focus too much on the actual hp number. Dynos do read differently. Focus on the difference in hp and gains achieved from adding these mods over the base pull.

 

Their was a guy who made a thread last summer when he swapped out his stock TB for a stock Titan TB. Plugged in w/out any said issues. Don't know why he did it, but I don't think he saw any gains. Stock for stock, they are both the same size.

I can only assume that if the stock Titan TB plugs right in, then a ported aftermarket 90mm Titan TB should be a direct fit also.


*Edit* Rob posted the link above my other post. Thank you sir.

 

This is a reasonable assumption. However, are there any 90mm TB's for titans? As far as I can find, they are using converted 90mm LS2 units.

 

what I found on the titan forums is that there was a company who made a very limited batch of conversion Ls2 TBs for the titan. they plugged right in but they only made 10 of them and they were $700 plus a core.

I'd be interested to see how much diameter makes a difference in the TBs on this setup. I know the vk throttle body could probably be bored out close to 78mm. not sure if its worth the hassle though.

 

Your right, it is a LS2 conversion, but they are still able to keep the stock ecu.

For those who are interested...On the Titan forums, there is a forum member that started making aftermarket TBs. It's called the PGM Throttle Body (full kit system). With this throttle body kit and an uprev tune, the Titan guys have been having pretty good success with it from what I've heard. Maybe "Uprev" can chime in.

I haven't read all of it though...

but "PGM Throttle Body" comes up with a ton of hits when searched.

 

they have a thread there guaging interest in 90mm throttle body made by accufab. the price is predicted to be $400 or less. i plan on buying one when they come out.

 

Link?

Great info, Subscribed. I'd like to see this plenum and throttle body combo on a stock 350z with dyno comparison.. If they power is good, I can see everybody selling their plenums and spacers

 

If this plenum and throttle body comes available I will test it against my Cosworth plenum and stock TB.

 

Sasha, have you had a chance to do any CFM flow bench testing to see the difference in airflow with this plenum vs the stock plenum?

 

You have a machinist that could make those bends?
