Here's the Dyno:


Mods:
OBX headers
Tanabe exhaust
AEM CAI (my filter is dirty as fuck)
VAFC- just dyno tuned. Gains were: 10 HP and 8 TQ

Numbers:
250 HP at the wheels,
214 TQ at the wheels


Not too bad, but my Z will eat her up!

mattg

why does the sheet say fly wheel hp/tq?

AkuraCLS

it's just the place set it up like that..it's accually at the wheels..
here look at Ram's dyno chart..

mattg

those numbers are really high. you should be able to run a high 13 sec 1/4 and trap over 100 if they're true.


you should be more like 230whp/ 204wtq with those mods.

whoa, 10hp and 8lb/tq for VAFC tuning?! I haven't even LOOKED into gettin a VAFC, let alone know wtf it does. Is it really worth it to get it then? And where did you get it tuned? Nice numbers

bigguyonbike

wow! those are 13 sec numbers.

I'm not sure about that (re: the 13second 1/4 mile). The Dynopack is a nice system, but it generally shows higher numbers than a Dynojet.

The Dynojet is using an inertial roller and the Dynopack is hooked up without the wheels on (it hooks up to the hubs). The losses from tire slippage and wheel/tire mass/inertia go away, and the method used to calculate HP/TQ is different. The Dynopack "brake" style dyno with variable slew, and the other uses a fixed-weight drum.

It's a nice system that can vary the step time and load. However, it can be a little hazardous to compare a given dynojet dyno to a Dynapack and divine what it will do at the track.

akuracls, the dyno chart is off of a CL-P?

That "250hp" number on the Dynopack is probably about 20-25 hp higher than the number a dynojet would produce.

Good gain from the VAFC though...

darrinb

i dynod 250 on one of those dynos too, its w/o the wheels tires

allmotor_2000

It's a 3% to 5% gain on the dynapak - we have discussed this in the past. You will probably dyno 237-242 on a dynojet.

The chart says "Sams CL-S auto" ... I'd be surprised to see a CL-P make that much power with mods listed.

YMMV

typeR

me too ...my dyno was a mustang dyno though...

AkuraCLS

yah it's w/out the wheels/tires.... it took about 1 hr to tune, and Shawn Chruch is a very nice guy. DYNO DAY!

allmotor_2000

AkuraCLS's car is a CL-S, I installed his headers etc. The real purpose of his dyno session was to tune the V-AFC. So... the dyno shows 10 more whp, what's the big deal For those who care so much about whp... take the car to the track. Driving skills and car preparation are far more important than 10whp!

allmotor_2000

AkuraCLS - are you coming to the meet tomorrow?

mattg

i meant if those were true dyno jet numbers the car would be good for a 13 sec. pass. i say that because most of our low 14 sec. autos are making ~ 235whp and ~ 200 wtq.

his mustang dyno numbers are in line w/ a modded 3.5L on a dyno jet.


i guess it's just the difference between dyno's.




nice gains from the v-afc. that's what matters.

Chaptorial

That freed up a healthy amount of power.

Nice #'s.

AkuraCLS

yah i'm going to try and make it...

AkuraCLS

thnx guys
