In the past couple weeks we have had the opportunity to test different intake manifolds on our 1.8L daily driven project.Our tested items were
a stock itr manifold, IBspec ITR manifold, Edelbrock VictorX, and the Edelbrock performerX. The setup on our car is very simple but has proven
to be very effective. It sees roughly about 450 miles a week and runs on nothing but 93octane.

b18c1 block with CTR pistons on gsr rods
All honda bearings,seals,pumps,and belts
pr3 head with portflow standard headwork
Full omnipower valvetrain set
Blox Type 3 cams with skunk2 cam gears
Spark racing long tube header
RSR gt2 exhaust
Buddy club headgasket
Reused over and over thermal intake gasket
professional products 68mm throttle body
Tuned on Crome pro

For each test we just wanted to see what will perform best and give us the best overall powerband for our benefit. We used the same aem 3 inch cold air
for everytest and tuned air fuels and timing accordingly. The only things modified on each manifold was the throttle body opening. We just portmatched
to 68mm to accept our throttle body. All runs are on 93octane and through the exhaust.


Here is our first initial runs with the untouched ITR intake manifold.



We went for our first trip to the track with this 202whp setup. We went 12.6@107.


Then we moved on to the IBspec ITR manifold. For those not familiar with it, it is and oem ITR manifold cut open and cnc ported on the inside.



For those curious on how the two stack up together, here is a layover of the two.



Next up was the VictorX. We already knew it was going to suck ***** on our setup. We just had to know for sure to eliminate any what ifs. It worked out so horrible that i didnt even finish out a full out tune, it wasnt even worth it. So take this chart for what you will, it just doesnt work well with our motor.



Here is a layout of the VictorX vs. the IBmanifold. It speaks for itself.



Next was the perfomerX, which ran away from everything else. Its priced right and fits like ****, but it made some power!



Here is a layout of it against the IBmanifold to give you an idea of the gains.



We went back to the track with 213whp and went home with a 12.2@112.8


And now since we knew which intake manifold we were staying with, we decided to finalize the tune. We moved the cam gears around a little,played with intake length, and tossed a bpi vstack at the end of the pipe. Look at the gains over our previous best.



As you can see we increased horsepower and torque, but the real gains are in the powerband. At 9k we have 15 more whp. We could rev the car out a little further, but we need to keep this car reliable. Its his only ride to work. We will be returning to the track this thursday in the hunt for 11s. If you noticed on our parts list that there is nothing fancy or expensive, thats not by coincidence. This was originally intended to be a simple budget build for my buddy to do hpde events with. We took it to the dragstrip out of curiousity and now are on the hunt for 11s......on an oem pieced bottom end......on pump gas.....in a true daily driven street car. WISH US LUCK!!!


Videos of our runs at the track are on our myspace @ http://www.myspace.com/profunction

I still get PM's from time to time. We never made 11's.

The car got rear ended at about 55+mph on the highway. It was good while it lasted.

That is a nice piece of work.
Thank you for sharing this info. Now, this is what HT is all about.

Wow, the PerformerX is where it is at.

I know people have been waiting a long time to see something like this.

thank you!

question: were all the manifolds ported to match the 68mm throttle body?

I'm shocked at that Performer X.......still ugly as **** though. Thanks for the test!

importfan2

good info....


so whats next...hahaha

MikeySpec,
Amazing result.

Could you tell us which intake lenght was the best with the Performer X ?

Hopefully 11's? Well, if anyone wants to donate headers for testing.....im up for it.

The best length for overall powerband was a drag race spec intake that sits outside of the headlight housing. We used a simple 3 inch 45 degree bend along with a straight section. The v-stack barely sits outside of the headlight.

Great info, thanks for sharing.

I suppose you're running that intake without filter.

Have you done any test in street setup with same intake lenght and filter but into the hood?

MikeySpec

On the street setup(aem 3 inch cold air) the power will not hold itself as well. It starts to drop power off early at about 8600ish. We run the tuned intake for drag racing only. For hpde use we run the aem setup as well.

I think the aem doesn't hold the power because is less efficient and has different lenght.
On the same intake tube lenght you should try a velocity stack like BPI or Prototype with a K&N filter and possibly an air scoop in front.

Next month i'm going to dyno my engine with similar setup (S2S2, Mugen intake, B18c with 12.3:1 top coated Wiseco, ITR head, Hytech header & exhaust, IB blox intake manifold) and i'm regreatting i didn't get the Performer X.

I hope to be in the same ball park.

P.S.: What's the valve job on the standard Portflow work you got?

MikeySpec

The portflow headwork is just the straight normal standard 1000 dollar head work. As far as the v-stack test.....even with the vstack on the aem, it still wouldnt hold as much power. The drag race intake is a little bit shorter than the aem with much less bends.

I would like to know as well and if the Performer X comes with both (primary and secondary) injectors bosses or it's a special order.

They do not have the fuel rail for the secondary's yet. All manifolds come with the secondary injector holes, they are just not drilled all the way thru, you have to that.

GREAT GREAT TEST to your time in tuning & swaping

b19coupe

Nice test. I would love to get my hands on a PerformerX and test it.

makes sense. and id be willing to bet they are too far upstream in the manifold to provide a solitary source of fuel. maybe if you upped the psi a little higher than normal.

basically, im just a stupid ricer who thought of the proposition of cleaning up the engine bay a little more with a bottom mount fuel rail....just kidding....but no...seriously.


hey don, it looks like i might not be moving to FL afterall. i was looking forward to meeting smith, wesson, and turbo so much.</TD></TR></TABLE> Florida's loss. I think the upstream injectors will be OK, might have to bump the idle 25 REV's. Emissions at idle will be worse, but mid-high running will be better. I have one on the dyno now, it was better mid and lost a few top to a Skunk Pro manifold, but I have found a TPS problem, so I cannot say for sure.

nice test mikeyspec .. now its time for a 2.0L b-series setup

mx621

great test , i would like to know how the performer x would do against my SK2 ported manifold???

projectTeG

id like to see a pro-series IM(untouched) vs the performerX(untouched)
