I LOVE the new look! the front end looks SICK!

 

The kit is awesome! i'm extremely happy with it. I wouldn't worry about reliability at all. Especially if you are going with hondata. Most of the problems encountered that i have read or spoke to the people who have the kits were either install related or exhaust related. my car runs great.

 

Put my Mugen header back on. Everything runs great without any problems. I think the thing that the Jacksons were worried about are for headers that have larger primaries that the stock header. Most aftermarket companies except for Megan have tried to keep the size difference in the primaries almost the same.

From what Leonine said you should be able to run the base kit with header and cat back as long as it is all 50mm and the headers have nearly the same sized primaries as factory. If you plan on running all of these things plus a test-pipe you might consider using the upgraded injectors.

 

Ok So Simple Question...i Have 60mm Cat Back Skunk2 Exhause..and Stock Headers..i Should Be Fine...i Just Want A Yes Or A No

 

Leonine - thanks for you candid assessment.

So has anyone, manual or auto taken the car from 0-60 and
timed it? I don't need accuracy here. Is it under 9 seconds even?

 

I'm sure the 0-60 is less than 9 seconds, even with the base kit and no exhaust upgrades.

Throw in a full exhaust/header and injector upgrade, I'm 100% positive that it would be under 9seconds.. unless you're looking at the AT kit.. then its a world that I don't wanna know about.

I'm going with the hondata reflash, and highboost kit as soon as it is available.

 

You do not need an exhaust at all when you supercharge your vehicle.
A stock exhaust setup is completely fine with the supercharger kit.
50mm or 60mm is not going to make a difference.

The official m/t dyno graphs on the official website show +23whp with a header, injectors, cat delete and 60mm exhaust. I think some of us wanted to get in on a few of those extra whp with the injector upgrade, but it doesn't seem possible so far with 50mm exhaust + cat converter.

The stock exhaust header was specifically called out as a major bottleneck in the stock exhaust system.

 

i think that is 20-25 whp over the stock fit with the base kit. the dyno with the injector upgrade was something like 45-50 whp over a bone stock fit if i recall correctly. that's some pretty nice power over stock.

 

Exactly, several of us spent $$ for a header, some bought the $$ injectors, etc. But who has installed the injectors successfully without CEL besides any beta testers? I'm hoping for a more friendly a/t kit release...

 

So I'll be just fine with the injector upgrade to your A/T kit, aftermarket header, stock cat-convertor, and a 50mm catback exhaust?

Ok.

 

I'm testing out how the car is reacting with the Mugen header and 50mm catback ( I have the same as yours) with stock cat W/O INJECTOR UPGRADE and it feels great. It feels like I picked up tons of response in the bottom end, will have to dyno it to verify that. From what I could obtain from Leonine he's currently running with a header back exhaust system w/o injector upgrade and his car is actually staying within safe limits.

Once I get the car on the dyno I will verify this with an A/F ratio reading to make sure everything is within safe limits, as of right now though, it honestly feels as though I can run this kit w/o injector upgrade.

Thanks Tom. Looking forward to your results.

I gotta wonder why it says on the KW website that the injector upgrade is REQUIRED for guys with headers and/or cat-delete then...

 

good question. i think waaaaay back they said it was because if you run a header an exhaust, you have all this extra flow, but with not enough power to push through it, or something along those lines.

but real world experience, as posted here, seems to say that if you have got a 50mm exhaust and/or headers with no injector upgrade, you will be fine.

 

Any vids yet guys...?

 

I would take and post some vids, but there isnt much point. With the base kit and stock exhaust on the M/T I really cant feel a whole lot difference between before (had full exhaust/cat delete/race header) So if I cant feel much difference, doubt would be able to see any. I sure hope w/the Hondata upgrade/bigger injectors and putting my full exhaust back on I get a nice increase, cause so far I really dont think its worth what it cost.

 

I'm not so much focusing on the 50mm exhaust piping as the larger diameter on the primaries. From what I understand a few companies (Megan) made headers that actually have a pretty large increase in primary sizing, which in turn made the car run leaner. You should be able to find some of these post in past topics regarding headers.

From the info Leonine provided me, he stated that he was running a Full 50mm Header back exhaust system with Mugen header on stock injectors and had an A/F ratio in the high 12s.

From this I drew that the difference must be in the header, and from my understanding Chris had always ran his car with the Megan header. After comparing my stock header to the Mugen (similar primary sizing), I determined that I should be able to run the Mugen header w/ stock cat and maintain a safe A/F ratio.

I will verify this theory with a dyno run w/ A/F readings later today

 

thats weird...and very disheartening. the dynos from kw with just the base kit insinuate a pretty dang good amount of power over stock.

 

awesome, keep us posted.

 

Sorry guys was not able to make it out to the dyno today. I will definitely have it done by Saturday though. Tomorrow is another day of work.
