you lose a little bit down low and some mid as per their testing.

again this is a normal HR intake Manifold which has longer intake runner Vs the VHR intake ,
Longer runner vs short runner is = more Mid-power Vs top end

now their testing was with an unmodified HR Vs a modified VHR which already has an advantage in the top end 7000+rpm Vs the HR which their advantage is the mid-range

unless you are running most of your time in the 7000+rpm, a similar modified HR intake manifold will yeild better result.

dont get me wrong , im not bashing their work.

It's hard to tell which lines are which, but if we know m370 makes low - mid power over stock, than this does too, but not as much and has better top.

edit: let me clarify. We know the Z1 mod will make power in low, mid and top over stock, but low - mid is not as good as M370. We need a M370, Z1 and stock best run graph to actually see all of this.

I'll see what I can do for you guys on my next tuning session.

A Normal HR modified did not yield better numbers. We tested that set up when performing our manifold tests.

ok,

it did not yield better result , where?
if you say the top end 6800+rpm then its normal , but I would be very interested to see an actual graph with both HR / VHR modified as you do.

If I get some time I'll be happy to test it. However at this moment there are a few more pressing things on the plate and this may have to be on the back burner a bit, as there is testing being performed with many of our prototype products on the company car.

Thanks for the answer

I will also be testing a ported VHR intake manifold Vs my ported HR I did in December 2012 on my Dyno tunning session in April if I havent sold my exhaust setup before the race season here.

Hayyyyyyy

If car parts are involved, it's all worth it.

Yeah, it's hard to make out with so many lines, but after looking closer, it seems like there is some mid-range loss and mainly just gains up top. That's why I asked for a simplified averaged runs comparo graph so we can see what is actually happening throughout the range.

mag_black · 01-16-2014, 09:20 AM

John, do you guys have any dynos of the tomei exhaust? Appreciate all the stuff you guys are doing for us.

Looks like I'm buying the plenum also when I come and pick up the exhaust! As always, great work Jon (and everyone else at Z1)!!

Jon, please check your PM's please when you get a chance

Thanks

Can the z1 intake manifold be ran without a tune?

It is highly highly not recommended.
