I finally got the chance today to dyno my car again. I went to Tag Racecraft and used their Dyno Jet.The results are not what I was hoping for but I am still pleased with the increases over my stock numbers (213 HP & 187 Ft/Lbs)

The car put down 250.2 HP and 234.4 Ft/Lbs. The torque number is the one that I am disappointed with, but like it has been said many times before, a dyno reading is only a number. The car still hauls ass

I don't have a scanner so I can't post up the graph yet, I will try to have it up by tomorrow. I got some really good comparisions though while I was there. They save all the dyno pulls that people do when they go there. On file, he had a car with GM Stage 2, a car with the old Intense Stage 3 and now my car with the new Intense Stage 4. The other two guys are members here I believe so they can chime in if they read this thread. All of the pulls were done on the same dyno with fairly close weather conditions. The comparison is as follows:

Gm Stage 2
Outside Temp 13C
232.4 HP @ 6750rpm
207.5 Ft/Lbs @ 4400rpm

Old Intense Stage 3
Outside Temp 14C
245.2 HP @ 6500rpm
205.3 Ft/Lbs @ 4000rpm

New Intense Stage 4
Outside Temp 20C
250.2 HP @ 6250rpm
234.4 Ft/Lbs @ 4050rpm

As you can see, the toqrue from the new kit is far above that of the old Intense kit and the GM kit but the Hp is practically the same

Now, a few things that I noticed while looking at my graph. The torque hit hard at 4000rpm, but it quickly drops off and doesn't maintain much of a flat line. It drops all the way down to 175 Ft/Lbs by redline whereas the old Intense kit remains at 195 at redline, only dropping 10 Ft/Lbs from the peak number posted at 4000rpm. Mine dropped nearly 60Ft/Lbs.

The next thing, and the part that worries me the most. My car stops making power at 6250rpm. In the last 750rpm the car loses about 15Hp where it should continue to climb. From the way it looks to me, the car needs more tuning to get everything working perfect. The Intense tune is a great base tune but it clearly needs some adjustments to reach the cars full potential.

Overall I am still very pleased. By installing the Intense kit and an Injen CAI I gained 37Hp and 47Ft/Lbs. Not bad for only spending around $1000usd Now the hunt begins for my additional 15Hp and 25Ft/Lbs!!

its all about the torque man, thats a pretty large increase in torque for a one stage increase
just for ***** and giggles do the boost bypass mod, see if you can keep the numbers goin up, altough im not positive if the tune is supposed to take care of that problem, its worth a shot

Intense claims the torque should be in the area of 260! That's what I was expecting and hoping for

DanJHartman

lol damn i just went and read the same thing, thats crazy, but think of it this way, somthing is wrong because your shutting down nearly 800rpm's shy of rev limiter. thats a lot of HP and TQE to potentially show on a dyno sheet

eastcoastz

I though it would be a little higher. Spooner put down 260whp, 225wtq with the Stage 1 with a 2.8 pulley.

I didn't shut it down. I ran it all the way to 7000rpm. The car just stopped making power at 6250

That could be because of many variables. You can't really compare cars numbers from different parts of the country on different dynos.

I know I can't really compare mine to Intense's proclaimed numbers but I figured the HP and Torque should be a lot closer to one another

DanJHartman

i know, im sorry i didnt word my post correctly, but thats what i meant to say. i doubt your torque #'s would be any higher, but you should have ran at least another 15-20 hp more

SSKING

nice,,, now how about the results of stage 5?

2006ArrivalBlueSS

Do yourself a favour and take it to another dyno - Tag's is unreliable. Just look at my numbers with just a CAI.

selfinfliction

every dyno is different, they're used as tuning tools, not testing tools.

snowcrash

Do you have a "stock" dyno? Because those tq numbers are nice. Esp if your stock tq was under 200. Then thats like almost 40tq gain.

As other people posted dyno's are better for tuning and getting a baseline, gains etc. Just because you read on a dyno 250hp doesnt always mean your @ 250. But if you baseline at 200 (same dyno, same weather) then you know that your mods gained you about 50. At least thats how i look at it.

Still nice numbers though. But i feel you about wanting higher numbers, i want a stg4 or 5 myself and would like the 260/260 as claimed by them

Re-read my post. Your question is answered on the first line and in my signature

CTCOBALTSSS

You have to post a pic of your Dyno sheet. All those numbers you wrote down look wack. The numbers don't jive. Not to mention you're not even hitting the rev limiter. Let's see your real dyno sheet!!!!

BooSSted

iTrader: (3)

I'm not hitting the rev limiter? Why do you assume that?

CTCOBALTSSS

Because non of the numbers you wrote down show 7,000rpm. That's where the rev limiter is. Old GM stage 2 you show 6,750 not 7,000
With the Intense kit you're not even close, you wrote 6,250. You can go up to 7,000rpm. Lets see the real dyno chart. Why are you not hitting 7,000rpm???
Check out my Dyno. That's 7,000rpm!

BooSSted

Because those RPM's are where the peak power was reached. Re-read the post, It states that the car began to lose power between 6250 and 7000.

J_Rod

Thats pretty good numbers. Intense finds a way to get the very highest numbers, thats just what they do. I dyno'd 238 horse and 218 torque with my intense stage 3 with the MAF-T and that was here at 4200 feet above sea level. So your numbers are a pretty good gain. Stage 5 is where you are going to get the HP from due to the 2.5 pulley and ported blower. Good numbers bro. I can't wait to get my stage 5. Just gotta get the girl her ring first lol..

CTCOBALTSSS

I did read the post. Where is your real Dyno Chart??
I know your numbers are wrong.
I have GM Stage 2 and as you can see by the dyno in my sig, GM Stage 2 horsepower just keeps growing all the way up to 7,000rpm. Your numbers that you just wrote down and my numbers that are on a real Dyno chart don't jive!
Not to mention you should have more power with that stage 4 than what you wrote down. My point here is these numbers are weird. POST THE REAL DYNO! Congratulations either way on your stage 4!

See, take a look!

Ok, I am going to lose my mind on you. I don't have a scanner, how in the **** do you want me to post the chart?

The numbers are NOT wrong. I am more than capable of reading a dyno graph. What you have and what you car does has NOTHING to do with what you think my car "should" do. Your in a different part of the world, different altitude, different temp, DIFFERENT DYNO. I posted up numbers comparing cars with different kits in the SAME PLACE, close to the SAME TEMP and most importantly on the SAME DYNO. If you want to doubt those numbers then you can go right ahead. I really don't care.

I will post the chart when I get access to a scanner.

glockglade

I have a theory that you are overspinning your blower with that small pulley and there is too much heat after the blower causing you to not gain any hp. If the dyno was done in 4th gear go back and let your car totally cool off and warm it up on the dyno till the temp is at 160 and then let er rip in third gear that should keep the heat down. Also you could get the NOS intercooler sprayer and that should help as well. Anyways good results but after reading that I will stick w/ my GM Stage 2 kit and put a header on it's not worth 700.00 for me to gain 5hp and 10ft torque reather get the 4-2-1 weapon r header.

Well you can compare my numbers to the stage 2 numbers that were done on the same dyno. You will gain much more than 5 hp and 10 ft/lbs

Jim@Tagracecraft

2006ArrivalBlueSS ...I beg to Differ the Dyno reads correct. We have a new main Ecu unit that was replaced a month ago due to a power surge we had.

Regardless the Car made Great Power and has made the most out of all the Cobalts we have seen.
The only thing i could attribute to the lower tq number is some heat soak.
All in all great Car !!

thedak

Same Dyno... I agree................

think i may be paying u a visit in the near future
