What's up, fellas!

Has anyone installed the TTR intake manifold? I'm thinking of purchasing one and using it with my 2.4l throttle body. Share your thoughts.

Which injectors would be the best performance for a N/A setup? 33#, 39#, etc.

Thank you,

I think one or two people have but nobody has done any dyno testing to provide. If ya get it do some testing for us

 

this is not intended for use on an NA application

 

The website says "aluminum intake manifolds replace the factory plastic manifold on 2.2/2.4l Ecotecs". The only place it mentions forced induction applications is "2005-2007 Chevrolet Cobalt 2.0L (When converting to turbocharged, and will replace the supercharger intake manifold)" but I would definitely buy this if I were turbocharged.

Which injectors should I use?

Doesn't really look like anyone has tried it na yet. Aaron should loan one put to a 2.2 for some testing na-wise lol. I have read a few of njhk's posts and it doesn't really sound like this is meant for the average na build.

 

If you are cammed, and/or have most every basic bolt on, you should start to see a need for this. mid and top end will show an increase. Same concept of when members use a 2.4L intake manifold on their 2.2L, this will just allow for a larger pull top end.

You will need what ever size injectors gets you the ideal A/F ratio for your setup through tuning.

Best guess is 4-5 already have this on a 2.2 or 2.4L that is normally aspirated. (not forced induction)

 

Thank you for the info! Since I may not supercharge my 2.2l because gas prices are going through the roof, this is an alternative. My mods are ZZP mid-length header and 2.5-inch dp, 2.4l im and tb, cai, Magnaflow 2.25-inch catback exhaust and tuned. I plan on upgrading in the future to larger injectors, zzp long tube headers and dp and a 2.5-inch exhaust.

Are there cams available for the 07 model L61s yet?

 

Comp cams are only available for the 2005/06, as on the new ones they have another sensor, which the cams do not have. You might be able to push off the lobe on your current cam and put it on the comp cams? I believe someone has done this before.

 

Encourage/harass them to come forward with their findings

 

They will come, each to their own, we will not post customer info for privacy reasons.

 

in fact, stocks are fine and cheaper to change.
in my case they are not max out yet.

 

I really cant see this being much of a replacement for the 2.4 intake mani, and yes huckerage knows, stock injectors are fine. Check out some of the dynos done with the 2.4 intake mani. Interesting to know more tho.

 

I don't think you'd need one on an NA motor. the 2.4 can handle 400 hp just fine...

 

i heard that for a N/A, you ll need longer runner. .

it is possible to customs one for 600. patz24 did one for boost application


here something that should look on our cars

Skunk2 Racing: '06-'10 Civic Si Black Series Intake Manifold: Photos: '06-'10 Civic Si Black Series Intake Manifold

 

2 things here:

1. Anything can "handle" 400 HP, but the amount of HP you actually see as an improvement. Just like stating a 2.5" exhaust will still flow at 400HP... Same case here, this will flow better yet.

2. In addition to #1, this also is much stronger, at 12-15 psi, on the stock plastic one, we have seen them blow up many times, they cannot handle this pressure for a long time.

So there are multiple benifits, and these are a fraction of the price of other similar manifolds on the market.

Justin (Blades) for example gained around 40-45 HP just by switching out his manifold to the TTR one.

The ones that know, are getting this, being we have produced a total of ~15 of these already.

 

is justin has a dyno sheet about that gain.

 

Yup either PM him or he will post here...

Found the "After" adding the intake manifold mod:



Original before intake manifold and tune:



Nick (BYT) and Justin estimate the manifold alone offered about a 40-45 HP gain... The other half was tuning. Nothing else changed.

 

we are talking about NA application ? right

 

No as stated in other posts (brought up many times) you will NOT get 40-50 HP just by this intake manifold on a NA application. Most likely 15-20 HP is a potential/entitlement, on a full bolt on application, NA (all motor).

It will allow for a more aggressive tune, as you will flow better on top end, as these style manifolds do (just like Hondas, toyotas and other NA applications use)

In addition if you ever would go forced induction you are all set for the intake manifold.

 

If you are referring to the dyno sheets then no. That is a turbo swapped LSJ.

 

Yup as we just stated. Turbo applications from the LSJ to turbo will see the most gains from this mod.

 

Off product topic. But I have been talking to the SAE team at my school (UTA). During the summer, some of them are offering to help me design, build, and test a manifold for NA ecotecs. We are going to use my 07 2.2L. Mods in sig.

 

if you have questions about the mani let me know

 

Thanks Justin for offering help.

Everyone else can PM us with questions also.
