In a couple of my resent posts regarding the loss of low end with a cc306 and stock heads

Well I found a stock dyno (well K&N) and the dyno from the stock headed CC306 provided by xxsaint69x (hooker LTs, 1.6 RRs)

After I got both dynos I used PS to put the stock headed dyno run onto the stock car dyno. both dynos were SAE corrected dynojet.
I know this wont be perfect as its two different cars in different locations at different times, but for what I wanted I feel that it helped me enough.
I felt that enough people had the same questions as me so I feel that I should psot my graph that I made.

the grey is the stock headed CC306

the numbers matched up pretty much perfect +/- ~2 from the transfer

Hope this helps someone else.

 

Thats COOL. Awesome idea.

 

interesting chart. Looks like the guy with cc306 needs more tuning, just some thought, he could contact madwolf who knows big cams pretty good (cc306, gm847). Also it looks like cc306 makes no power under 1700 rpms, which is not true, but I got ported heads. What I noticed in my car is that if I put a more restrictive exhaust, my car makes plenty power in lower rpms, but slows down in higher rpm's. However, when I put true duals with bullet mufflers, I don't even catch tach needle above 5000 rpms, car is flying like a ****. So now I am getting a cutout to have low rpm's power in the city, and higher rpm power for when I need it.

 

The dyno started at different points (and ended as you can see to), I did my best, and I dont know if he has tunning, I'm sure he'll see and chime in for us.
but even bad tunning it answered my question of if under 3k rpm it has more or less power then stock.

If someone has a better or even an other dyno of a stock headed car with the CC306 (or I guess an other big cam) I can make that compairison too.
a stock and then cc306 with stock heads on the same car would be all too perfect.

 

I really hope much of that is sarcastic....

 

"I really hope much of that is sarcastic...."


Not really, those are the observations I made with my car by switching exhaust systems. Wish I had a dyno in my garage, could post some numbers

 

It doesn't really matter, but that dyno looks more like a K&N + cutout dyno.

Ideally we would compare a dyno of hooker longtubes, and then with only the cam swapped. Someone HAS to have one somewhere .....

I wish i would have started my dyno a little lower like around 1800 rpms, but i started at 2600. I don't think mine drops off quite as hard as the 306 on the low end, but it also doesn't quite have the punch of the 306 at 6k rpms.

Nice job though on the paintshop hack

Sorry, i was referring to the tuning comments. 350+ hp out of stock shortblock and heads is big power.

I agree with your exhuast comments to an extent.

 

Well I think it had a catback.... but again, I cant find a fully stock dyno, and I cant find dynos of in between stock and getting to the cc306 like jstu headers and stuff.
But when I go to do it I'm going ot try my hardest to keep enough money to dyno at a few stages.

oh and it was photoshop

 

true, 350 hp is too much for stock heads

 

It was probaly marcin (xxxsaint69x) who yoru referenceing reading about.

330 rwhp??? He already has 350 rwhp (from tuning it on the dyno with a wideband himself i believe)

 

My bad for making a mistake, I was looking at torque numbers

 

Isn't it a pain searching for that stuff. It's out there, but if you don't bookmark it, you'll never find it again.

Now that i recognize that is the ws6.com stock dyno, your right that is doesn't even have a catback. Most would agree though that its significantly higher then most peoples with JUST a K&N. They have the advantage of having perfomed those dyno pulls when the car was new and in perfect condition. I compliment them for being extremely carefull controlling the conditions like temperature for repeatability. Being at 5000 feet means that they probably have a hefty correction factor and that may also contribute to why their absolute numbers being slightly high stock. Just speculation though. And of course every dyno is a lil different

I'd love to have a dyno and perform all those progressive dynos. I couldn't afford to dyno my car just after my exhaust install i had to wait for the exhaust plus cam vs stock (well close to it).

I meant photoshop, paintshop is pretty weak, hehe.

lol..whats goin on in here.....
i made 348 rwhp without a dyno tune. I tuned little bit with my EGT guage thats about it.

yeah, what is going on here.

sorry, i thought you were tuning it yourself. Atljar did his own tuning, was i thinking of him? Not the stock tune though, just not a dynotune?

My main point was that you were already well above 330 I thought it was a smidge less then 350, i was actually just searching for your name to look at your dyno myself, hahaa.
