I just got my truck back from the shop with some BASELINE Dyno numbers.

1999 4.0 OHV Auto 4X4

Both numbers at the wheels on a DynoJet
HP ~ 128
TQ ~ 180 foot lbs

Not to shabby for bone stock...cant wait to get the Mod's back on and see what they actually do...

If somebodys got the STOCK numbers for a SOHC please post em if you would.. ::caugh::Jared::caugh::
:)

 

not bad!!

 

I think Coy Dyno'ed 178hp stock...

Dont wanna burst your bubble lol...

I think even Jared, with his 4x4 dyno'ed 168 or something...

 

At what rpm? Post some dyno sheets so we can see the power curve, peak numbers mean very little...

 

Spelled "COUGH" wrong..

 

where's that middle finger smile...

I will take a pic of the dyno sheets in a bit.

I was told that Jared dynoed at 135... 175 wouldnt be bad and would be a much more realistic number but what I really care about is the Torque, Torque moves metal right... :D

(dont forget were not comparing apples to apples, OHV has 50 less HP right off the bat)

 

lol, i know...

If Jared dyno'ed 135, im flying to cali to slap him...

 

lol... I'd do it for ya.

I was thinkin about this while I was eating dinner and relized that saying those numbers are "good" probably wasnt the best without adding that I'm saying that they are good for that motor with 107,000 miles on it. My goal with moding this thing is Torque, I dont race or speed to often so HP really doesnt mean much, but I'll race anybody up a hill offroad and thats where Torque helps out. So yea... thats it. I'm just happy I beat those pesky 3.0's...lol

 

When I dynoed my truck i got
02 4.0L SOHC AT 4X4 4:10 gear
211 Tq. @ 2000 RPM
165 Hp. @ 5300 RPM (I think that is right I will have to check)

I will post my Dyno sheet when I find it.

 

Here is what Coy dyno'ed

178.6 RWHP
217.5 RWTQ

 

Last year, I got:

127 RWHP at 5100 RPM
161 RWTQ at 3400 RPM

This was at Delk Performance.

Mods were: SSD CAI, Straight Piped Exhaust, 180* T-stat...

 

well when K&N dynoed my ranger i had
128.6hp stock
after K&N i should have 137.1

remember i have a 3.slow

 

That setles it, I'm gettin the V8... damn 3.0's....

 

bbwwhahahaahahahahaaaa!!!

 

Torque is the only thing the dyno can measure. Horsepower is a calculation.

 

3.slow < 4.go

i have no idea what i'm sittin at as far as horsepower goes, but i know my buddy with his modded 3.0 cant keep up, and his is a 4x2, 3.73 gears, single cab stepside...he has the total weight advantage too.

just keep moddin it...remember, we're trucks....not lambo's....dont try to overdo it, keep it realistic

 

today i had mine done i got 188.0hp and 221.6tq i think that is good for a base line

 

And HAS to be by definition. HP = torque * RPM / 5252

It is related to RPM and you can only directly measure it, so-to-speak, at 5252 RPM where torque=HP.
