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







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!!!

The car went as quick as 12.0 and as fast as 114mph. We never got a good dial in after making over 230whp on e85, it should've been good for 11.80's@114+. We soon after built a 2.0L setup that made a good amount of power....and then the car got stolen. Thanks ********.



Just for grief purposes, heres what our new setup(2.0) put out vs. the 1.8L setup.

Or if you want it tested on a similar 1.8L that is in this thread....send me a manifold, but it has to be for a GSR head.

thanks.

thanks for the reminder.

Just happened to have this picture laying around.

ps, thanks mikey for this test. great job as always.
