SRT Ram 150 Nitrous

PBJ tune and a good bolt-ons combo I would guess, a stock RC truck baselined 426 WHP on the same dyno about a month ago, so its not like it reads high, always SAE, smoothing 5#'s which are the lowest you'll get on a dynojet. Mine made about 445 untuned with no headers (catless exhaust and CAI only). Blaines truck (SVTFreak) is within about 10WHP and 10WTQ with no headers on a dynojet.

Those runs are on M+H drag radials, stock tires went 12.06.

Sorry for all the questions, just curious why the #'s are low. If the truck made 400whp baseline then thats fine, but most are making more stone stock, thats why im curious.

Justin
so what are your "good" bolt-on's ?

dyno's are too erratic........ i thought that SAE was for equalizing different elevations, humidity,.... what's "smoothing" for ? and why can't everyone post actual #'s ? :dontknow:
oh well, i guess the 1/4 mile tells the tale.........:burnout:
 
yep still stock and still together for now! that was with a one fifty shot. i think my best NA dyno with tune was 460hp/520 tq
 
Because I dyno in Florida humidity. No one dyno's high here. The weather altitude is always around 2400ft even though I am at sea-level. You should know that Justin.
For example Justin, your all motor run in your sig-post up the uncorrected chart over the SAE chart for Moparracing to see. Smooth charts both to zero for him to view the difference.

The correction factor should help you then, but its hurting you. Your uncorrected #'s are higher than your corrected ones. If I dyno here in high humidity on a hot day, the corrected #'s are higher than the uncorrected ones, it would be no different for you. The dyno takes into account humidity, temperature, and barometric pressure, all of which are used to calculate the density altitude.

My uncorrected #'s would be the same since it was done on a 92* day with approx 2900' DA (note correction factor 1.00), but smoothing 0 would very likely net a few more HP/TQ from the jagged lines. I dynoed mine in the middle of summer (which st. louis routinely gets above 3K DA). When we did Dom's turbo truck his correction factor was .97 because it was in october/november, so his uncorrected #'s are quite a bit higher. Heres my dyno chart:

Im only curious what the baseline is because the NA #'s are low and with headers, full exhaust, and tune is would normally be in the mid to high 400's. Gains from the N20 seem about right based on a 150 shot (62 NX pill, 64-65 would be a larger shot obviously). Im not turning this into a swinging contest, thats not my intention at all, the #'s just seem low, especially the N/A #'s, and im curious as to why. I looked at your stock 06 viper #'s are they are spot on for what they usually dyno, so I dont think your dyno reads low or anything like that.

I am with you J, I never had a stock baseline, that customer came in with those parts, I added a SCT on nitrous, not his NA numbers, which I could have done had we more time. He was concerned with spray only.

With the SCT in my hands his N/A numbers would probably fall right into into place, then again, you get those trucks you would swear were built on a Friday afternoon.

Here is Automatic SRT 10 with uncorrected against Standard correction to check out.

actual numbers vary too much sae puts everyone on the same playin field......if i posted my actual #s that day i would be closer to 1130 rwhp.........
 
Its all there, Belangers with my own true dual 3" catless exhaust, my CAI, VEC3, and Joes tune. I have a x-metal TB now (since september) but havent dynoed since these #'s. Absoultely no head/cam/intake work done, and my #'s dont reflect that I have that stuff done, it would be mid 500's easy on a mild h/c setup. Joe tuned another truck with 4.88 gears (John Stuttles old truck) and the exact same mods (belangers, catless exhaust, my CAI, my NX setup) and it made about 620/810 on a 190ish shot. The gears killed the WHP #'s some.

Marty, what are the SAE #'s on the QC? I didnt realize you didnt tune the N/A portion of that RC truck, thats what I was curious about.

you guys keep this up its a world of knowledge. I've been looking at the Zex system myself #82047 universal truck kit

That explains my truck at Joe's last summer:D It made 463rwhp on his dyno with the 4.88's;) Which I thought was low then he explained to me why the #'s were lower:rock:
 
Here you go, SAE same quad cab.
