Why would you want a new intake manifold hooked up to restrictive stock intake piping and filters and inefficient stock headers?

 

I wouldn't, I'm just trying to figure out how much power the manifold
will add.

 

Theres so many variables that can be attributed to how much it will make though. Sticking it with OEM parts will probably show minimal gains at the most. Every application could be different based on different intakes, different headers, different cat-backs etc. However we can get a general rule-of-thumb on what the manifold will do based on the tests done by Weapon*R.

I'd be more beneficial to know what the manifold is capable of doing with other basic bolt ons then how bogged down it will be with stock parts.

 

The manifold will come with a Fuel Computer at the price of $550 on the website... Pre-orders will be $500...

It will be available in 1 month..
I do have some in Hong Kong where we made some for the cars in the pics you see in earlier posts.. If anyone is interested i can ship them from Hong Kong.. if they are willing to pay for the freight .. PM for details..

 

If you can sit tight for another two weeks I am having a bunch of new mods installed down in Vancouver including the WR Intake Manifold.

This will be a nice way to compare the performance as I will be driving down with only an I/H/E setup (about 900km) and then a return trip with everything installed.

I will be posting up my review shortly after with pictures, product impressions and performance results. I have an assortment of other aftermarket engine goodies also going in... I think the overall performance results are going to be a pleasant surprise for a naturally aspirated car

 

Where are the individual exhaust gas temperature readings from each cylinder you were going to supply?

 

When did anyone say this?
That requires alot of work.. wonder who was gonna do that?

 

I've read the whole thread and saw no mention of someone going to get exhaust temperature readings from each cylinder.

(Why would you want that information for an intake manifold?)

 

Just go back and read the entries in your other post and you will see that I asked the question. But your right you said it was too expensive. Ever think of getting an IR thermometer gun like they use to check track temperatures? They are not that expensive and you can use it for other things besides checking EGTs.

For cojaro's kind inquiry EGTs for each cylinder will let everyone know if all the cylinders are getting equal amounts of the incoming air charge which MAY not be the same because of the shortness of the path to the closest cylinder compared to the distance to the end cylinder. Honda has internal deflectors to even out the flow differences (look inside your stock one and you can see them) but Weapon R has yet to post photos of the inside of their's or explained how they direct the air flow so it is an unknown at this time.

 

There are 4 airhorns / Velocity stacks for each runner..
Arent you getting alittle bit too technical here for a intake manifold for a Fit that produces 99hp? I mean were not turbo'n the car where it would blow up from a intake manifold.. I can understand if were talking about turbo's.

I dont think a IR heat gun will tell you exactly the EGT's of each cylinders because each tube can get effected by the tube next to it.. the best way is to use EGT's..

IMO for a car with such a simple bolt on A/F's from the Exhaust should be good enough.. If it is that important for you.. Maybe you can do this for the community. I for one think it's not worth the time..

 

FYI the honda fit doesnt have deflectors in the plenum... I studied the flow of the Stock IM before we designed this one.. The stock one is a LOG which feeds the cylinders..

 

I agree EGT measuring would be best directly measured by probes in the system but you said it was too expensive and I was trying to provide a cheaper alternative. An a IR gun is sensitive enough to read varying temperatures in adjacent cylinders exhaust pipes.

If you look at the cut away manifold photos on TOV you can see the deflecting airflow directors inside the stock manifold.

You don't think it is important enough to worry about the quality of the parts you are trying to SELL to members to simply answer some questions about the parts?

And no it is not too technical no matter how much the parts cost or which vehicle they are going on potential CUSTOMERS questions should be answered politely no matter if it is turbo or na.

In fact it would matter less on a turbo setup because the boost pressurizes the entire plenum area but na it depends solely on atmospheric pressure to fill the cylinders and the difference in distance between cylinders with an open (or log your term) plenum COULD cause airflow differences in individual intake tracts POSSIBLY causing differing cylinders to have different A/F ratios therefore we are only trying to determine if this phenomenon is occurring in your product.

If you think it's not important to answer potential customers simple questions, no matter how much you think they are too technical for us less technically advanced members intelligence to understand, about a product you are trying to convince us to buy that is your right.

 

i alredy paid forthe pre-order and was just wondering when the manifolds are gonna ship?

 

I was wondering if we have ship dates available for the pre-orders you took???????

 

so you taking pre-orders? I'vee couple of prices. What is the total price. I don't wanna pay then I get "oh and add this for tax and shipppin". What is the total price on the pro-order. Thanks.

pm me would be the best way cause I might forget to recheck this thread. I want it mostly for looks to be honest.

 

i want one
pm me for pricing please

 

Leo,

My WeaponR intake manifold does not come with the EGR routing back to the manifold so that has caused the engine check to go on. The EGR circulation has been blocked, Do you have a way to bypass the EGR valve?

 

Most mass produced intake manifolds don't have deflectors. Not sure if it's mentioned or not, but the Fit doesn't have these.

EDIT: Oop...I see it was mentioned. lol I'm so slow

 

Also, if anybody else has some suggestions here I would be interested to hear them.

Thanks!
