Wow can't wait, I got an HR and I can feel that there is a lot of untapped potential in this bad boy.

Vq35Hr and Vq37Hr only difference is VVEL and 200mL on it, otherwise same architecture/design.


Will the HR/z34 headers be interchangeable?

 

Yes they are, like I mentioned before this project we did extensive testing with the headers on our Z1 370Z.

 

Tuning is a big part of that number! outstanding none the less...

 

^ my thoughts exactly. This must be a pretty aggressive tune.

 

I'm awaiting these headers... I have uprev tuner version, art pipes, catback, mrev,5/16spacer,momentum cai and these z1 headers when they come out for my 06 z. Hoping to get 275whp

 

Why don't you guys run the upgraded plenum from MD?

 

What was the SAE corrected number?

 

How are the clearences (fitment) of your headers?

 

I think the MD manifold is only for the VHR motor, its basically an HR manifold made to fit the VHR . correct me if I'm wrong though lol

 

^ your right

 

luv it!

 

Didn know that. Dont do enough study for chit that wont fit my car lol

 

Im noticing this recent trend of "I have information I cant tell you guys, BUT here are my results anyway so you're left wondering what else was done aside from the mods listed"
Really my question is, are we ever gonna know about the "undisclosed modifications" ?

 

hey Redline,
I can understand them doing that. They might have spend alot of time & work on it, & they wish to get rewarded/paid for it when the products are for sale.
After I bought my slicks about 2 years ago, my 60' time was slower than the drag radials they replaced. That day I drove around the track's parking lot, trying to sell them Good thing nobody bought them, because after a long, long time of learning & understood how to use them. Today I make great 60' times. I share almost everything with almost everybody, but I would hesitate telling people everything I learned that took me two years to figure it out

 

completely understandable, I appreciate good R&D for parts , would just like to know roughly what was changed or modified, and if theyre even gonna sell those modifications. Im sure they would sell well around here.

 

I think we can improve our intakes by channeling more air from underneath the car toward the intake openings. Also improving/changing the parts after the boxes toward the throttle bodys. ????????????? Make sense?????

 

Yeah I thought I posted my thoughts on that in a different thread but may have forgotten to click reply, I would start by changing that accordion looking piece of rubber between the air boxes and Throttlebodies to a straight through design. Then Titek ducts to get the air in. I created a thread not too too long ago about some ideas I have ill PM you the link.
Heres a pic of the Titek Ducts, sucks theyre a bit pricy

 

I'm not sure what you mean by aggressive? We spend an enormous about of time in every tune to make sure that it not only makes great power, but is as safe as possible.

315, with a 249rwhp baseline

We are willing to provide the same package of unstated modifications in house, we currently have no way to produce the items in a quantity large enough to meet the potential demand, so until then this set of modifications will only be done in house by myself.

 

Thanks for replying
Quick question, did you guy run into any issues with the stock injectors running too high of a duty cycle past a certain whp?

 

We ran out of injector @ 342rwhp on pump fuel with a safe AFR, of course this was on our Z1 370Z but the flow rates are the same as the HR. We are currently in the process of upgrading the injectors and a few other things, hopefully to set the VQ37VHR bar even higher.
