I was cruisin the FAQ and i saw something that I"ve never thought about b4.

A guy said that he has a "dip" in power where the second set of runners are suppose to open up.

He said the p28 ECU fixes that problem and thats what he was looking for.
Is he wrong in this or what?

 

Hmmn.. Ok, maybe I should have worded the topic different.

The ECU is set up for dual runner intakes.. If you put a single stage runner intake, wont the ECU be expecting something else to happen at 5500 rpm, compensating for extra fuel and whatnot?

 

yea you'll lose power for sure. you'll lose tons of low and midrange and gain a lil up top.. if your using the stock p72 you would bog out at 4500 rpms when VTEC engage and at 5500 there is no secondaries... even with a chipped p28 you still wouldnt make as much power as a stock GSR manifold. those manifold only work well with cams or turbo.. not stock app.

 

If thats the case, why and the HELL are all these freakin n00bs swapping single runner intakes on there GSR's and b16's?

 

is this different from the skunk 2 pro seriies? cuz i was planning on getting the sk2IM but my car is relatively stock,??

I'm pretty sure it doesn't have a dualrunner manifold.


Most of the time people are doing internal mods with the single runner IM too.

 

Oops... Forgot that the b16's dont have dual runenrs :S

My bad.

But still, I've seen amny many "mod lists" that include single runner manifolds on near stock GSR's.

Do they make any aftermarket dual runner IM's? (never searched to find out)

 

no they do not...

 

I didnt think so.. I couldnt recall ever seeing one.

On my car, I could notice a night and day difference in the high end, it also showed on my qtr mile track times as well. With just intake, header, exhaust, and ctr intake cam, I was running a consistant 14.8. As soon as I swapped out that intake manifold with a single stage manifold (skunk2) and made myself a chipped p28 with a custom map for my mods, I started running 14.5's. People w/ gsr's who swap over to the single stage manifold usually have cams or a semi built motor. Those who do it with fairly stock motors (such as myself), is in the process of building an NA motor.

I'll be using Hondata when I do my stuff (which Ive decided agaisnt using ITR pistons and am sticking w/stockers) so it wont make any diff to me, but I definetly didnt know that you had to reprogram the ECU goin from dual runners to single (never put much thought into it really).


And a side note, Memphis stylz, I'm goin to Cecil Sept 24 w/less weight and an ITR header/ITR gutted cat/SR intake and I'll be launching different (no bogging)..HOPEFULLY, Maybe... I can knock off a tenth or 2.

 

make sure you got a good set of rubber...your car can hit low low 15's...my buddy mekong84 suffers from the insufficient driver mod...he ran your same exact times and traps..which is hilarious cause thats what I ran when my ls had NO motor mounts that werent torn (all torn, plus I was MISSING the front tranny mount completly)...wheel hop city on every shift

Damn, didnt knwo there was a technical term for it.

I can have a set of Yokohama AVS Es100s (205/55/15) on Rota slipstreams on when I run, but they are 55's instead of the 50's I've been runnin on.. so they're a lil taller.

How much of a diff you think it'll make?

 

u know what, i didnt feel a power loss with my GSR. i did feel small gains around redline, and with a chipped 28 i felt little to unnoticeable difference between p72 and p28.

might just be me but w/e.

yes u will be able to use ur AEM CAI for GSR with a skunk 2 with a bypass. i have it myself and everyone and their mom will tell u it wont fit.

you didn't feel a noticeable difference since your chipped p28 probably didn't have a good program that worked efficiently with your set up.

yes the gsr intake will fit onto a gsr head running a single stage manifold, BUT it doesn't fit correctly and it looks funny. Some people have had their gsr intakes hit the underside of the hood. Also, there have been dyno on h-t in the past to show that those aem bypass valves actually cause you to lose power when using them.

yea i think aem has a disclaimer on their website saying it negates the power when you use it

Anyone installing a cold air intake for power is just fooling themselves. The real gain from an intake is improved throttle response. I doubt what little turbulance the bypass creates will negate that, though it certainly could negate the 1hp gain you'll get. Now, this statement is for an otherwise stock or mostly stock engine. Something really reworked to need alot more air will benefit power wise from freeing up the intake restrictions.

eh, for the .5hp, my daily will live. it l\ooks fine imo, but for showcars i can see your point,

as for the ecu, i had the ecu tuned for my car
