Dynamometer Results & Comparisons - dyno results 402

i have a 2002 camaro 6 speed and dana 60 diff, engine is a 402 with 10.6cr and patriot stage 3 heads, cam is 236-242 and .650 lift with my 1.85 rockers,fast 102 intake,t/b 102, maf 100mm 104mm lide, 42lb inj, pacesettre headders and off road pipe with 4'' mufflex exaust, i made 545rwhp and 516tq, then tried my stock ls1 maf(having bucking issue with the 100mm cruising) and made 532rwhp and 511 tq. this was on a Dynojet outside in cool 60 temp. i am verry satified, is this normal numbers for this combination? these were corrected numbers

Great numbers with mild H/C setup , Dana rearends and 10.6 CR Congrats man.. :D
Any graph or vids?

Id be extremely happy with those numbers with budget heads & LT's and going through a Dana 60!

Those are some very strong #'s with an S60 and they seem high, but it may be just a great combination. My numbers, which are off by 30-40 rwhp, were on the 10-bolt (drop another 10-15 rwhp with my S60) .... damn that seems high or maybe I am just jealous! What does the car ET??

Awesome #'s! I am also having bucking issues with my 100mm MAF?? Sick of it already.

Yeah same here! PITA to tune with 100mm MAF and decent cams. Good numbers!!!

my goal was 500rwhp. i also found the number on the hight side, but we passed 33 cars on the dyno that day, and most of the cars that had been dynoed before on other dyno was pretty close to the original #, temp was 66.80F,29.86in-Hg, humidity 40%, sae 0.97, smoothing:5. is there any # more to kno if this is good info, i do have the sheet, just not sure how to post, no track time , have no tires for traction, no use going to the track for now. at 5000rpm and up is were the big maf works over the small maf, i am going to stay with the small maf for drivability reason at the cost of 13hp, i don't mind any opinion on these numbers being to hight, i looking for reason's to beleive it

Sd tune fellas!!!

Sd tune fellas!!!

Ditto

my tuner recommended against it as he said it will not run as well in hot weather?? thoughts, comments?

Numbers seem inflated. Take it to the track though. I'm guessing 128-129 traps consistently with maybe 130 here and there.

Piss on SD!!! VE/MAF together have been proven time and time over to make the best power and torque. Ive tuned a few 100mm MAF with large cams, take your time and if you have to tune in OL.

i drive in a large range of temp and elevation, 55F to 100F sea level and mountains here, that is why i stayed away from SD, the tuner(carlos) i am working with now by e-mail and phone from texas(i am in NB Canada 3000miles away) told me that there would not be much diference between the 2 maf, i had a hard time beleiving it until this week, another well know tuner here tried all last year (email, but with no phone calls) to get the car to work and never sugested to swap maf, he had told me no probleme get the 100 maf.with Carlos he hook's up to your computor and talks to you on the phone at same time and explains every thing he is changing right in front of you and ask question, looks at you log and correct acordingly

Did you swap the TB as well or just the MAF?

Are you HPT?

only swaped the maf and tune for that maf, using hp pro

Ok do challengers and 300's and magnums and Challengers run crappy in the heat or cold? High in mountains n low in valleys? NO it's in the tuner! Some tuners got it, most don't!

i am not saying that it can't be tuned, what i seen on my camaro is that with the 100mm maf is that at low rpm when there is not alot of air flow and the way the air is coming accross the maf sensor, there is turbulence and not all the air is being read, i wached the air flow on my hptuner and the numbers are all over the place, i put a screen in front of the maf and it made it better and even clocked it to a different position and made it better, but still not perfect(not as good as the small maf) it is not the tuners fault when the reading is not constant. my car is feeding from the bootom and the air has to turn almost 90 degrees at the air lide, the maf is 1 inch on the lide where problably most of the air is in the upper part of the maf.

Im also against the sd tune, just have never been a fan, if you can tune your own car its not a bad idea but if ya cant i would stick with the maf,thats imo though, great numbers ya know we need dyno sheet/vids/pics, i would be super happy with those numbers

I've seen a few things that Carlos has done over on CF, some big numbers coming out of there place.

If you have a concern that SD tune will not adapt to weather & atmosphere conditions, ask Carlos. I live in the mountains of BC & will run in either SD only, MAF only or the hybrid combination of both.

SD is tough to hit the cells, when tuning on the Mustang you can load steady state based on RPM or MPH....nice. The problem when tuning that way is the heat & shit you melt, such O2 & OPS wiring.

as a comparison for dyno numbers we ran 33 cars that day, just before me was a 2008 corvette ls3 stock automatic that put down 363rwhp, does that seem right for that car?

here is my dyno sheet with the 2 pass, one with the small stock maf and the other 100mm maf

Think im jealous also lol...... but i was dynod on a mustang dyno and have changed intake n exhaust since then

Tell me more about your Mustang dyno numbers before and after your intake and exhaust change. I am just not convinced from the numbers I have seen (this thread aside) that the FAST 102/102 TB is worth the $$$ and if a change from 1-3/4" to a 1-7/8" headers is worth the trouble.

As far as the numbers from this thread, maybe the air in Canada is way different ... much more dense ... more oxygen content .... yea that's it, different air up there makes for 10% increases in power ... lol.

those are some crazy numbers for your specs

anyway, good luck with your setup

like i said before i find the numbers on the high side also, without changing anything on the dyno, what could be the reason for my high numbers, the vette in front of me ls3 2008 made 363. the 69 charger 440 6 pack with lots of work made 480rwhp running lean, and had dynoed the engine alone at 577hp, that seems fair for those cars

You are correct, the numbers for the cars you described that dyno'd before you were "spot on". The only way to really tell are ET's! Just bear in mind that using "drag racing calculators" are for perfect conditions ... perfect traction, perfect suspension, perfect DA, perfect shifting and a perfect power curve (i.e. reasonably linear power). So, just because you plug in an ET and a hp figure in a drag racing calculator, doesn't mean THAT is the ET you can expect, especially the first time out.

i am figuring that my numbers are at least 10% over what they should be. there was also a 2008 vette with 427 headders, no cats, cold air, black widdow cam and tune that made 593rwhp wich i figure is about 10% to much. what do you's think?

Here is link comparing a stock C6 Z06 & I'm going to assumed tuned, then headers. Compare the torque numbers to yours.

here is my dyno sheet with the 2 pass, one with the small stock maf and the other 100mm maf

You should probably fix that valve float before you break something.

speed demond, could you explain more, how do you see it on my sheet, and how sure are you, could be, i have 1.85 ratio rockers and about 20000 miles on gold springs

I havent dynod yet but 3 things hav changed intake/exhaust(headrrs back)/sd tune...i say a difference and gain switching from 1¾ to 1⅞ on my 346 and would run nothing less then those on any motor.

What kind of "Mustang" #'s did you put down before the mods intake / header / exhaust mods to your 403? The 4" bore heads, FAST 102 & 1-7/8" are exactly what I would like to ad, but, I have not seen huge hp/torque per dollar increases to justify it.

Currently I am working on dialing in my suspension ... engine mods may not be needed to reach my goals.

Idk what mustang dyno it is tuned at slowhawk. With a untouched 92/92, lpe maf, 3½ single cutout made 519/474

519/474 through the S60?? Those are great #'s on a Mustang dyno vs. a DynoJet dyno!!! You shouldn't be jealous at all by the OP's #'s. Any ET's with the new or old setup?

Its ok i always like seeing the power #'s. But went 11.2 @128 old setup, car weighing in at 3775 me in it shitty 60' needed shocks in the rear so the suspention was squating but then unloading cause it to spin ...gota get this thing tuned on the dyno now then maybe a track day
