Well today i drove over to ProMotion Tuning today for a dyno. It wasnt as easy as a drive there, i had to sit in vacation traffic for 35mins(2miles) before pulling into the dyno shop. All i was thinking was OH GREAT a heatsoaked engine. I think i will continue to write pointless rambles ...and not post any dyno numbers.

On all my pulls i did have the drivers side foglight out so the air was blowing directly on the filter. Maybe I forgot to mention the dyno pull was done in 4th gear.

STATS:
03 CLS-6speed
AEM cold air intake
XSPower Headers

Done on an AWD DynoJet Using front rollers only.

First pull: 248whp
Second pull: 246whp

On the third pull we took a 15min. break which helped me yeild my best pull of the afternoon.

Third pull: 253whp and 218lbs of torque Graphs are on their way!!

Im pretty much at sea level where i dynoed and will be posting my dyno graphs as soon as the company emails them to me

 

253 whp is amazing for just headers/intake.

doubting thomas... let's see the graph. what kind of SAE adjustments were made?

sounds a little high, but it is a 6speed.

 

Yeah that's a bit high for your mods.

 

253?? Holy crap, that's awesome. I've been thinking about getting a baseline dyno of my car while its still stock so I have something to compare it to when I finally get some mods.

 

damn! those are some nice numbers. cant wait till i get my ct cai from excelerate. thanks for the numbers

 

I thought that 253 was a little on the high side as well for my mods. I really dont know what the SAE Corrections are, care to explain? Im still waiting on the dyno shop to email me the three runs. Makes me wish I had a baseline dyno of my car when it was stock.

 

wow thats crazy... i just put mine in too and the throttle response feels better but other than that maybe i got a cupple of more horses compared to the Megans...??

 

Those are awesome numbers, really high for those mods.

 

Factory freak?

 

dyno variances

 

true. Well, 01s has dyno'd the same numbers on 2 different dynos, if I'm not mistaken. But I very well could be.

 

I will be posting the 3 dyno runs later tonight after my cookout, the dyno shop just emailed them to me.........maybe its a freak, i dont know. Maybe I should go to another dynojet.....

 

Well here is the graph for pull 3 that netted me 253whp. Unfortunately the place forgot to email me the first 2 pulls.
And yes the dyno is sae modified.



click image to enlarge and once that opens you can click again to full size. Too Much clicking for i'm concerned I'm a picture posting....

 

that AFR is FLAT. wow. the torque is a little choppy, but it says right around 215 the whole way. can't argue much on that graph. must have been a perfect day, perfect run, perfect conditions.

 

nice numbers! custom cams should put into the 270whp range.

 

I dont understand why the hp and tq seem to fall off at 6.5K? I do have a dip right before 4K RPMS on the graph which i think is that hesitation with the 6speeds, it showed up on all 3 of my dyno runs. I guess i just got lucky

I think Intake and Header is all im doing performance wise to this car. This is the first time I have ever dynoed a car, next week I might get my Supercharged Grand Prix a run on the dyno

 

The 4K drop is normal. Every dyno I did has it.
So we have 2 unreliable dyno's here. Anyone want to give a 3rd try?

 

the 4k drop is where imrc opens.

i'd like to see at least one more dyno. i am just very suprised by 253 whp.

 

cl-s are very sensitive to temperture change. a long cool down would account for the good numbers.

also, that's on par with a 350z with revup engine.

 

Rev-up engine?

 

The dyno shop didnt send me the first and second pulls, but ill call them and see if they can, my first 2 pulls netted me in the high 240 range...I do have pics of my car strapped to the dyno I should post



All Mine, the Rev-Up engine is the 3.5L in the 350z that puts out 300hp

 

the dyno curve is fine...all dynos have a range of variable and one shouldnt dyno race...it's a tunning tool not a my car in florida makes more power than yours in california....the track is the place to show that...take it to the 1/4...if it runs 13's at 100+ then id say the number is good

 

that would be one way to tell, but I dont race my car at all. Actually I rarely ever hit vtec.

 

With the six speed, intake, and headers you should hit high rpms more frequently. That is where you'll really feel the headers.

 

The torque on the CLS6 isnt bad at all, so there really isnt a need for high RPM's. But it could always use some more torque.

 

i wouldnt know about that

 

Do you recommend i go to another dyno???

 

only after you descide to add another mod and if you wanna know how much power it added...other wise it's just a number

 

it took so long, Ihad to get the DynoJet WinPep viewer to get the rest of the graphs. So here they are.

Sorry its blurry it's the best I can do......

 

All I can think is the dyno calibration is off. The charts look correct. Nothing that would tell you the car is not making those #'s. The TQ curve is a little flat. You have over 200 tq at 3K RPM? That doesn't make sense. Those #'s just can't be right. Look at the dyno postes on CL & TL's over the years & none of them are close to those #'s with those mods.

 

it makes perfect sense, right on the money.

 

Factory Freak?

 

Are you fun......(being sarcastic)?


Maybe it is a freak , i know we have them in the Grand Prix community

 

Take to the track make me a beliver

 

Well I hope this is correct, I'll be running the same headers as he is soon....

 

wow, good numbers.
what was ever the outcome of this?
correct, or not?

 

Tis a dead thread, last post was 2006, is it neccessary to revive such dead threads?
