Testing AAM Midpipes with Short Tails and Z1 Intakes.

SwissCheese · 12-08-2015, 10:41 PM

Isn't it true that with each new breather mod, the gains are not as significant?

Also, anybody have a relative idea of what kind of gains the OP can expect with a tune?

On both dyno plots on the uncorrected graph that has Z1 intakes, it's making more power up top. When we start looking at SAE results, everything gets masked in calculations.

Edit: Those cats are definitely bottlenecking the exhaust. I guarantee opening that up would gain at least 10whp no tune on RTP's or TP's. It's almost like confirmation that to get more power over a Nismo exhaust with an aftermarket exhaust, you need to replace your cats.

This was the case with my Z. I swapped out the stock cats for HFCs, after replacing the CBE, and I noticed an immediate improvement in how the engine performed. Night and day.

The car wont breathe better without long tubes or test pipes that is why there are no gains the flow is restricted by stock cats, my

With test pipes you should at 10 to 15whp or better. I saw 312 will Z1 smooth tubes K&N drop in filters, Art pipes and m370.

This was my exact plan as I have the Z1 intake and short tails already. Hoping to pick up the AAM mid pipe relatively soon. This news makes me sad

But as you guys said, 307 hp isn't bad without a tune. I guess I was being unrealistic thinking I would get in the 310 315 range without tune.

Great update, excited to see what a tune does!

It won't breath better without unchoking the OEM cats. Mine saw dramatic improvement with HFCs so you don't have to completely dump them to see gains. You just have to get rid of the OEM cats which are the biggest restriction in the system.

^^^^I agree, hfc or tp are the key to maximizing whp when it comes to the exhaust system.

Looks like Art Pipes are my next mod as test pipes will be a little to raspy with the short tails

1cintron · 12-17-2015, 09:33 AM

has anyone else here with the Z1 intake tuned their vehicle? I'm debating on whether to go AAM vs Z1. Currently, I have the Injen setup.

SS_Firehawk · 12-17-2015, 09:38 AM

Honestly, the AAM's were my first choice. I bought these because the black Friday deal wasn't going to make me butt hurt over a couple HP after a tune. I do like the filter design and there is no cutting required.

How many pulls were done when testing on each product? Just wondering.

I should be getting my set in today.

There were three pulls done each time. I have all the DRF's if you want to take a closer look.

The baselines were taken on a Saturday, everything else was Monday around noon to afternoon.

I plan on running a few more pulls when I'm back in town. I can see the intakes making more power up top where the common flat spot is.

Pretty sure I saw that they were done in 4th gear but I could be wrong.
