Got to tune the caR at R&D Dyno in Gardena; let me just say that Darren is very cool.
Darren agreed to let me tune the car, he was just going to make the runs. He ended up doing much more tuning than I had planned Some of you are familiar with the motor, but I will run it down anyway:
Block-sleeved ITR. Stock crank.
IB Wiseco 81.5mm 11:1 pistons.
Stock ITR head.
Something a little different here-Skunk2 Stage2 intake cam, but a Toda C exhaust cam.
Hytech header-Mugen cat back (new for me)
Various intakes tested (thanks again, Darren )
Two throttle bodies tested-RPM 74mm and RPM 70-66mm.
Custom JG sheet metal intake manifold.
RC 440 cc injectors.
Hondata.
Darren gave me a floppy with all of my runs and suggested that I download the WinPep software to view and print them. I did and gotta say I am loving it
First graph is a comparison between the way I received the car in July 2003 (stock with a JDM 4-1 header and an AEM CAI), and after it was tuned today:


The second chart is a comparison of the throttle bodies; I was surprised by this one. I expected there to be more of a difference between them, but they were pretty close:


Next up is another test that surprised me a little, Shawn's "Magic" velocity stack style intake vs an AEM CAI cut off to be a short ram. The short ram actually beat the "Magic" intake between 6-7,000 rpm, and was close at the peak:


I brought the car in untuned, with a base map that was kind of close from when I was running an AEBS intake manifold and Toda C's. I had been running the cam gears at +3,-1, but had them at 0,0 for the base test. Car was quite a bit slower on the drive to the dyno, so I knew that the power was down.



Final test was a mini intake test; we had already tested the"magic" intake vs the short ram. Here we tested the J's Racing against the AEM CAI (full length) and against the short ram. The short ram was actually the clear winner on this motor-disclaimer: your results may vary

good numbers. What kind of filter did you use on the short ram?

 

Great info.

I'm sure a lot of people will be surprised about the TB results.

 

Not really shocked on teh TB result....velocity of intake charge is FAR more important than sheer volume.

 

nice numbers

yeah what kind of filters were used

 

Good info. Thanks for posting it for us!

Also, was this with a GSR intake manifold? I'm wondering if the little bump in torque before VTEC can be attributed to the intake butterflies in the GSR manifold.

 

Must be fun to drive. thanks for sharing your results.

The air filter on the short ram and the AEM was the one that came with the AEM. No filter on the magic intake, and the J's used the filter that came with it.

There is an intake resonance at about 4,500 with the AEM CAI, and at 5,000 with the magic intake.

 

Wow nice info man, thankyou

 

nice setup.

 

Thanks for great info Todd....

 

Any particular reason behind the mismatched cams? I understand most likely for powerband adjustments, but what exactly? Nice #'s and info as well.

 

That's some nice TQ from a 1.8. What happen to the ITB's you had on there?

 

Todd, you make me proud...lol


Pretty soon the 1.8's will be making more then me...Time to rebuild

I have heard from a couple of people that these cams work well together. I had a set of each, so I gave it a shot.

Still have them; may try them again on other motors or on this one at some point in the future. I really need an EMS to get the most out of them.

 

nice #'s... with no port on that head

just curious what was the fuel PSI at?

 

What other cams have you tested on this same motor setup? I saw that you said that you used to use both Toda C cams. Could you give us an overview of the different cams you have used and their powerbands?

Nice numbers and thanks for the good info.

 

Here is the motor on ITB's and Toda C's. Hookup's dyno reads about 8-10 whp less than R&D's. Fuel pressure at 58 psi.




Last year stock block and head with Skunk Stage 2's, Comptech header, AEBS IM:

 

good numbers

 

Again, thanks for the great info your torque is where i want to be at; 140+ on a 1.8L

Yup, we are gunning for your title
Next up is a CNC'd head for (hopefully) 10 more WHP.
Goal for the motor is 220-not too many 1.8's making 220

Nope, but I do remember a few from here on ht..
Tony the tiger

Dennis the cop
Cheetah?

I have a plan that I hope will get me to 270 whp
