The dyno used is a bosche dyno. The power is given in kW the conversion is kW x 1.36 = hp .

The first dyno run is a stock ITR B18C6 motor, 4-2-1 jdm header, 11.1:1 compression (EUDM ITR...) and I had the AEM underdrive pulley kit installed...

Ploted at 97 degrees.
Max horsepower at the flywheel: 1.36 x 144kW = 194.6 hp



Second dyno run with, smsp header, highflow cat (smsp), magnaflow catback (smsp). There was a comptech icebox added but with the stock airfilter.

Ploted at 77 degrees.
Max horsepower at the flywheel: 1.36 x 151.4 = 205.9 hp



Comparison charts:
Red - Stock
Blue - Modded




Torque.

Red - stock
Blue - modded



The feeling between stock and the I/H/E cat is there. The torque difference is felt. The power difference is definetly felt. I also get 3rd gear chirp sometimes!!! I honestly was expecting a higher peak value but the overall hp and torque gain is very impressive. Tell me what you think.

i would like to see you dyno the car now at or near 97 degrees....20 degrees will make a big difference none-the-less good info.....SMSP quality stuff!!! 13 hp in mid is HUGE!!!!!!!!!!!!!!!!!!!!!!!!

And for the vid of the stock dyno run video:

awesome numbers
SMSP
always nice to see some smsp dynos.

 

This result is about what I've expected.

You can see that the peak power is at a higher rpm. And VTEC kicks in harder.
BTW. Euro ITR header is NOT the same as 4-2-1 JDM 96 header. We got our own EUDM header with 2" flange and small primairies.

 

Seriuos gains from just adding an Exhuast, Nice!

97 deg outside

 

Nice numbers but i was expecting more as well.

Was that a joke?

 

From the numbers u guys get in the states.....this from what i understood wasnt measured at the wheels so that makes like what 10 whp?


P.S- im talking about peak hp.

Who cares?

And 10whp up top is damn good for the exhaust.

 

It seems the OWNER himself was expecting more.
And besides he also got the comptech icebox for those numbers. Im not by any means saying the header isnt good cuz i KNOW it is VERY good.
Maybe our dynos are more accurate i mean a usdm itr could NEVER have more hp than an euro spec R (stock) but for some weird reason they do lol.
I even had the idea of selling my toda header to get the smsp but nobody wants to buy mine over here
Peace

 

i started off with the jdm header so its normal i dont have as much of a gain as USDM ITRs because I start off with the JDM header. Also the comptech icebox had the stock filter in it. The temps really had an effect on the power.

Do you know the power difference between your 4-2-1 JDM header and the stock EURO header?

Every dyno reads different in terms of peak values

 

I don't really know the difference. The power gains throughout the dyno curve are great. Really good stuff. I have yet to see the 400m times. But for now here's a run that ended a bit too soon against an ITR 18" rims, emptied the rear of the car. Agaisnt these parts no weight reductions 15 stock rims.

enjoy.

here there was a 3.5 car difference. I believe in the 400m ill have 4 to 4.5 cars ahead. When I raced him before the car mods done on my car we were exactly the same in the 400m.

 

RJ i agree with u. But like i said usdm R´s have more hp than european ones, of course that in the same dyno your cars have less hp and i was having references in your dynos thats all
For SMSP

 

Today we dyno'd 2 ITR's with the same idea. They had only the exhaust system changed and both gave much higher numbers.
This is the highest we got:

It was a 5th gear run to avoid wheelspin on the (too) slippery rolls. Thats why the power loss numbers are so high.
The header is a JDM Honda 4-1 with a 60mm testpipe and spoon catback. It had also a spoon airfilter.

These are great numbers!!


btw, the dyno is below sealevel!!

Was any tuning done? Mine is bare stock with the boltons...

 

Whats wierd is i had the same well 108 kW for wheel hp...

Proper tuning would yield even more impressive gains.

 

There was no further tuning at this car.
Just the 4-1 JDM header, testpipe, spoon exhaust and spoon filter.

The wheelpower is this low because of the high gear run. Plus the higher load of the mustang type dyno.

I personaly know this dyno and I have run my stock ITR on it last year. It gave 193 enigine HP

 

I also ran my car on the same type of dyno. It's used to high horsepowered cars (tuned up porsches). I also was in 5th gear for the dyno. I will do another dyno run once I change the intake around a bit. I'm still wondering why my results are different to others.

 

good #'s

 

Ok, you do that!
We dyno'd 4 differdent cars with 4 different 60mm exhaust systems. All with JDM size headers.
(HKS - Invidia - Spoon and DC sports) and they all had minimal 215HP at the crank.
This was done at 2 different dyno's

 

i was looking back and fourth on the two dyno charts comparing mine to yours. And I noticed something really bothering. I get my peak value at 7800 rpms. I guess he didn't want to go higher. Or my car really does peak at 7800. Look at my stock run on the dyno. It cuts off even earlier... Is this normal? I was lead to believe the curve on ITRs just keeps on going till the reve limitter...
