Well I had a bunch of gas used to get good and repeatable numbers but made many runs across the rollers. The quick and dirty info is that:

My code 3 seems to have gained 4 HP, boost went from 14.5 to 15.88 using the same dyno machine.

My horse power total is now 338.5 at the rear using the super cooler for the H/E upgrade. The water never got over 120 degrees in an 80 degree shop ( before the runs).


Those coming to see the runs at MIR drags, will see the October suprise which I have been fabricating and testing. This gave me the 12 H/P gain and moved the total boost up to 17.12 with the same pulley. This is a total gain of 16.3 H/P over my previous best pully previously. Bad news is the design change details are restricted and its release date is the 12th of October. More to follow.


My differential pulls are within 5 minutes of each other and it only took me to 1 minute to get the changes completed to prove this upgrade. The charts are below for your review, thats the good news. Horse power gains higher than this are going to be achieved by thoes who have bigger pulleys than mine. With a 185 I would expect about 19 H/P.


The Many runs at the dyno were to get it set up correctly, to get the boost readings working and to be SURE that the H/P gains are repeatable. The code 3 did not get me what I wanted but I report the information as accurately as possible.

ENJOY, WOODY

 

Very cool Woody, but you'll have to let us in on your secret!

 

I'm interested to see this secret mod but, IT WON'T SAVE YOU!!!!!!!!!!!!!!!

 

Did the dyno operator take it to rev limiter or shut down early? Do you have a tune with raised rev limiter?

Reason i ask is i bet youd have higher hp if the dyno pull went past 5750rpm.

 

We were at the rev limiter and as you can see the rotors get more effective at the upper end where the pressure rises a bunch.

What is good and part of my over plan is that the super cooler is keeping the I/'C temps down during many runs on a dyno. That is key to power gains, the ability to be consistant over changing conditions.

You can not just look at peak numbers. I charted it for you, as you can see the code3 pulley gave you big gains across the rpm range for both torque and hp. This is not exact since the charts did not plot the same exact rpms but it should be very accurate:

Woody might make some noise this Sunday with those numbers! He has about 10whp on me, but Ill get him on the line don't worry.

 

If you look at the chart I posted you can see the numbers dropping off on the top end, that shows that by opening up the restrictions such as exaust, headers and intake manifolds you would pick up more hp at the top end of the rpm range. I think he already has an exahust though, those 240 modified intake manifolds would make a great difference i bet!

Here is your psi before and after your mod:

What was your a/f ratio? I forgot to ask earlier.

 

If I may use a colloquialism....sick!!

 

Did not get the A/F we were trying to get too much data in a too small time slot - 1.5 hours. I also didnt wanna spend any more money because the plugs seemed to be a good color ( OD SCHOO ) you know. W DY

 

I have this strange feeling that I will be making similar power by Saturday.

 

Waldig are you saying the Code 3 SC pulley only netted 4hp ?

 

The numbers show the Code3 gives a pretty darn good increase on the low end between 2000-4000. At 4500 and up it flatens out to be close to the factory pulley. That matches what was posted on the early dyno's for the Code3 pulley. The crank pulleys see the increase pretty steady from low to high.

Another reason to combine the two pullies! Oh hell yeah!!

 

Thanks for the clarification of the C3P SC pulley numbers, I was starting to think I wasted $600 on it

I've often wondered if the crank and SC pulleys were both run what kind of gains we'd see

 

There is something going in there that is not making sense, WHY, HOW?????? to be continued???
Woody: and yes the about 4 is correct for the peak HP numbers as stated by others,Woody
Bottom end power is street wise great and is all good.

 

Not sure how you missed this: https://www.crossfireforum.org/forum...56&postcount=6

 

Yes,
I know of one C32 (Eleventeen) that is running the 178 and the C3 pullies together. I will be doing this mod. We will be hitting the track together soon as he lives 5 min from me. I would expect that car to run VERY strong. I am eager to see it! For me, I would imaging with the NW mani's, upgraded exhaust, C3 pulley and an ECU re-tune from LET, I will be mid to high 11's around 117-119mph. Did I mention Meth? Oh yeah, that too. :P LoL, this is my hope. We shall see though.

 

I found the original boost charts where the only changes were the let spacers, NW intake manifold, and a gasket matching of the head/intake manifold. Stock boost was up to 14.3 PSIG at full rev range in this configuration.

To overlay the charts the code 3 pulley got a total of 110 #/feet torque increase at 2000 rpm or a power gain of about 20 h/p (120 v.s. 100h/p)

The gain falls off and is about 4 h/p at the 5500 range. This is really strange and the object of my wonder. I did see the chart which lists the gains but still wish I knew how the early jump in torque and power fade so much. That is information, just do not understand it yet.
WOODY, ENJOY.
