So i got dynoed for the 1st time today
im not thrilled with the numbers i made but there not terrible and with some of the cars iv beaten im not really worried

1st pull was in 4th gear and i made 222whp and 207tq. but my iat2's were screaming up into the 180s=( didnt log any knock tho on my interceptor

2nd pull i asked him to do it in 3rd not sure which one is better to do but i made 235whp @ 6500 and 220tq @ 4500. IAT2s were much better only touched 150

afr was steady at about 10.8 but that was only watching my wideband they werent running afr on the dyno well i didnt wanna pay for it lol
im still on the base tune that i got from CA last august so all in all im fairly satisfied

mods are 2.8, 60s, ported m62, cai, vibrant header/dp and the hahn catback

also the conditions werent the greatest it was 90 degrees and 63% humidity
i went down with my friend who has an SC tiberon and he only made 250/221 and i put a few bus's on him on the way home =D

ill post up the dyno sheet later i love my tq curve tho 200+from 3000 to 6300

thoughts and opinions welcome

 

u could do better with cooling mods tuning is rich same as mine 10.9? i would think with 2.8 and port ud make more

 

yeah man you tune needs some work i have a k&n intake and a catback exhaust i made 217 on a dynojet there is something wrong there see if you can get it to lean it out some i heard 11.8 is good but do you have any cooling mods at all

 

yea i was really hopeing for a little bit more but im not running alota timeing bc i dont have any cooling mods to back it up im only at like 17degrees of timing right now i know guys get into the 20s and thats were the power is

 

check your h/e pump to see if its moving fluid. if not, hit it with a hammer until it does. then go buy yourself a new pump.
Get some cooling mods asap.

Also, what kinda timing are you running? mail tunes blow donkey dick. IMO you should be atleast at 250whp with your mods and a very modest tune.

 

ic pump is def working when im crusing itll be around 100 and even after a 2nd and 3rd pull its only in the 130s and will come right back down there was just no air in that place it was hot as hell
and 17degress of timeing
it wasnt a mail tune i live 20 mins from cobalt addiction i just asked for a really modest tune he turned the timeing down and added some fuel bc winter was right around the corner better safe then sorry

i know theres more power in it i just need a new tune

 

afr 10.8?

 

Here is mine with similar mods if you want to compare........

 

i no i made over 250 whp with that pulley. not sure what my afr and timing and all that was tho

 

thats the dyno sheet all i have is my cell phone camera right now

 

Why are your numbers STD, and not SAE?

I made 205whp/194lb-ft SAE corrected (what you should be using) and 215whp STD.

And you dont dyno in 3rd in our cars, 4th is closest to 1:1

 

hmm i always though 3rd gear was closer well then i guess my #s are really bad
i want to get a new tune and go back but $$$ is a little tight right now with school and all
as for the sae and std thing idk i just went down with my friend for fun its just how the dyno was reading i honestly dont know

all i know is on the street i can pull cars that make some good power ex stock ss/tc, mazda speed 3's,
and i hung in with a new camaro 40-100 i was at his back bumper. so i know my car has got some power
but if anyone wants to send me a good tune for a 2.8 and 60s be my guest

 

I figured that you would be able to put down some better numbers that that with your listed mods... Especially with that kind of AFR! Time for some cooling mods my friend!

 

meth. 5 gph nozzle and get the zzp heat exchanger. meth kits are really cheap on here. go to the classifieds. also, remember that dynos arent everthing. some read high, some read low.

 

Well this is a problem with many people, they rely to heavily on numbers. Its not about the numbers. If you're car has a good tune, you're fine. You can pretty much tweak a dyno and make it read whatever you want.

Personally, im only using a dyno to see how much power i gained from my mods, not necessarily to achieve Xwhp. Im gonna use the same dyno once i'm staged and see what i gained.

I wont even address the new camaro comment, im sure it was a V6, or MAYBE an auto SS (only 400hp). Definitely not hanging with an SS 6MT, sorry...110mph traps...

 

yea i know that dynos arent everything and i am still on a very conservative tune due to the fact that i dont have any cooling mods yet. im willing to bet that even as it stands w/o any cooling i could gain another 10-15 at the wheels with a better tune

im gonna work on getting a new tune and i have a heat exchanger in my garage i just havent had time to put it in yet so well see

and for perspective purposes my friend who i went there with the sc kit he got most cars w/ that set up dyno 270-280 and he only made 250

for the camaro comment i met the driver and he did have to ppl with him but he did say he was going full out it was getting really bad for me really quick i shut down at 100 to keep some respect bc by 110 it had grown to 1.5 cars and it was getting alot worse for me

 

Don't sweat dyno numbers too much. They are not the end all. Dynos are a tuning tool, thats all. At any rate, I am running 18 degrees of timing and put down 240 whp and 220 wtq with a catted down pipe, airbox mod, stage 1 HE, 2.8 and 60s. With a header and cat-back on top of that, you should be closer to 260, imo.

And you guys running 20+ degrees of timing.... were you dyno tuned, or are you guys "street tuning". Mine was showing signs of trouble over 18 degrees. Just wondering how you guys are pulling it off.

 

maybe tomorrow ill post up my tune on here and you guys can take a look at it i wasnt really dissapionted but now everyone is getting me down lol i have hpt and i looked at it i am running 18degrees at least i think im not 100% sure how to read the graph on it =/
i mean my car is "fast" now i wonder what i would think with an extra 40 whp ya know

 

I had an extra 40 whp last year then you, its slow, hell I have more now, its still slow

 

I've yet to dyno my car built and you can see my sig .... I do say it's all in your tune. I am running 21 * of timing with no meth or kr. It's all in the tune. I have my afrs at a slope starting at 12.5 at low boost and at high itlll drop to a 11.5 at top end

Did u look at ure iat timing table and p.e timing adder table???? And check and see if your low Octans and high octane are the same if not copy the high octane table and paste it to the low octane. I would change your fueling to a afr of 11.3

 

you afr is too rich up top and too lean down low, you should be commanding more fuel down low for torque purposes

 

20 degrees is not aggressive for a 2.8 if your iat2 and afr are reasonable. However in the case of the OP's high intake temps its a good thing he doesnt have alot of timing.

Street tuning with wideband > dyno tuning. dyno conditions almost never resemble the real world driving which will change things quite drastically.

12.5 to 11.5 is fine unless he is hesitating or getting KR. being too rich down low does nothing but waste fuel.

 

Yeah you should be well over those numbers...I did 232 on stock stage 2 with it sucking coolant.

 

This could be my problem then. Thanks for the info. The only cooling mod I have is a ZZP stage 1 HE and no way to monitor my IAT2. A/F looked good though. I plan on doing a dual pass soon, so hopefully that will change things and let me run more timing. Thanks again!

 

on the street my iat2's never see above 140 which isnt bad for no cooling and thats after going from a dead stop up till 120 or so i dont see any knock even on the 4th gear dyno pull he did when it got up to like 180 =( i was scared there it didnt knock
and yes my low octaine and high octain tables are different should they be the same???

im not sure how to change the what afr that its commanding
and i tryed to connect hpt to my car and it was getting an error so now i gotta figure that out

edit i think i just learned how to do it
