Disappointing Dyno Results

[SVTJAY]

Got the L dynoed today.

It was on a Dyno Jet

Here are the results

Pull #1 348.5 HP 438.7 Torque
Pull #2 351.8 HP 442.9 Torque
Pull #3 350.4 HP 438.6 Torque

Air Fuel was good at 12.0 - 11.9 thru the whole pull

I was hoping for something in the 380 HP range with my mods

2000 L
4lbs Lower
90mm Mass Air
JLP Air Induction
C&L True Flow Inlet Pipe
Bassani X Pipe, Spintech Mufflers
Boost Bypass
Predator
Tuned by RTWD

Ill post the dyno sheet after I get it scaned tonight.

Spintech? That's a new one to me. I've got a 00 and I think I'll probably have the same problem with you, just not enough power.

SVTJAY - Where did you have it dynoed? I got 347 RWHP and 417 TQ '03 stock. I am in Livermore also and would like to hear the spintech's

dynoed at Modacar here in livermore, PM me and we can meet up.

One thing to keep in mind is that a person on 91 won't make as much power as a person on 94. Also every dyno reads different, i've seen as much as a 20 HP variance in the two local dyno's we have.

Also, SAE vs. STD vs. corrected are all a big playa too. I agree they look low even all things considered.

Dynos vary. But your #s are pretty low. If everything else is right then your tune is off. A 4lb, and chip with exhaust ought to make around 380-390 rwhp or more.

Weather also has a lot to do with your #s. It's hard to compare #s though..My nearly stock 03 L made 364.5. But you should at least be a little higher than that. Maybe it's the tune :shrug:

 

[SVTJAY]

it was 70 degrees durring the pulls

Check the tune!

We (DFW-SVTOA) held a dyno day this past Saturday, and my very stock '01 pulled 356/425, very respectable indeed. HOwever, a guy with a modded '02 (4#, Airraid, magnaflows, single-blade throttle body, and a chip, not sure what kind) was pulling 400/520, or thereabouts, so there is something wrong with his setup, unless the dyno is FUBAR'd or jsut POS.


EDIT: We were getting corrected numbers off a DynoJet, model unknown, at Speedworks in Lewisville, Tx, ~75deg, ~70%+ humidity.

Might want to to check how you're truck was sitting on the dynoIf it was more to the back or to the front of the barrell, your numbers wouldn't be as strong.

The tech at Modacar is very thorough on setting the wheels on the top of the drum. I have had all three of my vehicles dyno'd there and have assisted on setting up 6-7 cars on the roller.
