Did some more cam testing today on my 2 liter ITR motor. I have been running Toda C's in the motor since it was rebuilt, and they have been dialed in pretty well. Today I installed a set of Skunk2 Pro 2's and spent a couple of hours tuning them. Spent a good half hour just getting them to idle smoothly, which they now do. Well the Pro 2's beat the Toda C's pretty solidly just about everywhere on this motor (both cams peaked at 262 whp):
:

I am pretty confident that with a little more tuning I can get them (Pro 2's) to work even better. The Toda C's were at +6, +3.5 and the Pro 2's were at +5, +4. When I have more time I will experiment with 1/2 degree cam timing changes to optimize power even more.

Back when I was still running a 1.8 liter ITR motor I tested some Skunk2 Pro 1's against my Toda C's. Once again the Pro Series cams primary lobes outperformed the Toda C's fairly well up until 5,100 RPM. In this case though, the Toda C's were better above 5,800 RPM:


I think that I am going to run the Pro 2's for the forseeable future in my street car-that is, until a better cam comes along...

 

Another great comparrison from ya man! Did you baseline with the gears set at 0 and 0 on the Pro 2's?

 

thanks

Nope. Started at +2,+2. The head is milled so +2,+2 is close to 0,0

 

gd info! Pro2's look solid

 

good info. btw how do you set the ratio for your dynapack runs? is it as simple as multiplying the final drive and the gear ratio?

 

anybody have specs of s2p2 vs. m22xx vs. m24xx?

 

I'm actually looking into getting some Pro1's for my next setup. Not quite identical to yours, but close.

So it looks like the Pro1s graph is more linear, but peaked just slightly earlier?

 

very nice info!!

on the comparison.

how do they feel on the street? the tq difference should feel alot better!

 

Good info as always.

 

Thanks for taking the time to share the results.

Pro2+'s.

I know I love mine.

 

id love to see a direct comparison of pro1's vs pro2's on a 1.8 motor looks good man

 

Dispointed to see that the Spec Cs didnt do better!

thanks for sharing

if you have a dial indicator the best spot for all the toda camshafts are at 1mm lift at TDC. that info comes directly from TODA JAPAN
this is a print out of toda Cs after the owner was messing with the car. lesson here is dont play with the car settings after it has been tuned.
prior to this the car made 147kw=236HP

I would like to see the m22xx / M24X tested against these.

 

Send Todd a set, then!

 

I would like to change out my cams from Skunk Stage 2's to the Pro 2's.
Next season I will try it

Just remember to bring it to us for tuning

O.K. so yesterday I installed an SMSP 4-1 header with no exhaust and started to tune the car. On the third pass the clutch let go Motor was on the way to making really good power. Torque improved significantly. New clutch in, going to try and tune it again tomorrow.

6300-I have not finished playing with that either-I am going to work on dropping it down to try and take advantage of the intake resonance.
