Dyno numbers seem to be off

So i have a 95 s14 with a s13sr20det in it current mods are
Precision Sc50301e
Full race manifold
Enthanlpy tune
740cc injectors
Greddy intercooler kit
Greddyintake manifold
Safc2
3inch exhaust turbo back
Brian cower step 2 cams
Fidanza 9lb flywheel

Tuned on a mustang chassis dyno today and made only 307wheel hp on 22psi with av gas, my afrs are 11.5 all the way through the rpm ban. Doesnt this seem a little low.
Have a friend that has a s13 kat dynoed at 370hp and every time we run i stay about a car ahead no matter what.

mustang chassis dyno. Dont have the dyno sheet on the computer yet but as soon as i scan it i will post it up. Im thinking there dyno may have problems, they dynoed a supercharged dodge durango and it dynoed 100 hp less on this dyno compared to the other mustang dyno it was on and both of them were corrected with sae so that is the only thing i can think of. The car runs really good and feels way faster then 300whp.

All dynos are different. I wouldnt worry about your dyno numbers. I made 430 whp on some and 370 whp on others. Track times and speed is what matters not pieces of paper saying what your car makes.

Get Track numbers Not Dyno numbers. Since your A/F readings seem to all be good and your tuned. Go to the track and Compair your time slips. Thats the only True test. All Dyno's are Guestimated.

Dyno's are just prep talk. ESP if you can't drive your car on the track.

7.65 is a good time.

I turn 7.80's with my rb. So your def over the 400HP mark. So No worries about the dyno!!

Is that a load based dyno?? Well put it this way, my 350Z put down 280whp and 263ft lbs tq on Motordyne's Dynapack. A year later, with a few more mods and using a Mainline (load based dyno) I put down 240.7whp and 218.4 ftlb tq. Just try a different dyno.

Dyno Dynamics reads the lowest in the industry.

We tune cars to over 380-450 on my bad boy all day

Imagine what number that would equate to on a dynojet

A LOT MORE

anyways

Dump the S-AFC if you are running a proper ROM TUNE (Which Enthalpy's typically are as close as you can get/safe/from accross teh country) YOU DO NOT NEED AN AFC.

The rumor that people hook up an AFC to help smooth out the fuel or AFR is total CRAP its BULLSHIT

EVERYONE STOP DOING THIS>

your just throwing your whole computer off and your adding additional resistance to the Air Flow Meter signal, which is no no.

AFC is a TOY, just like Tonka.

get a real EMS or get a rom tune that does not require major Fine tuning.

We have put several cars on our dyno with the AFC turned off on, or removed with rom tunes, they made no difference, typically they only made less HP with AFC manipulation and later ended in blown motors and broken hearts.

Control the motor's brain direct with any one fo these

-JWT Rom
-Enthalpy Tun
-Power FC dyno tuned by a decent tuner
-Haltech " "
-AEM (make sure you replace the trigger disc in the cas fyi).

-Cheers

Good luck with the stock axles. I broke Both of mine after 14 passes. I wish someone made a good set for the stock R200 6 bolt rear end. I run Full Posi, Welded.

What tires were you running? also 60' times?

smart man... i believe you own freddies old car? if so 400+whp shouldnt be a problem, get those axels thrown in, get some good tires for the rear(still 17x10.5?) ... but as for doing a full build.. there is no need, that car was properly built years ago and from what i know... has no problems...

but take it to ohahe in pierre, you'll run low 12's no problem...

Thats still a decent 60', I was cutting 1.6's with no launch control on 11.5 MT Et streets on 8 inch wheels.

You should try the gizzmo launch control. I just installed it on my rb and I now build 6-8lbs of boost on launch. I haven't got to use it on the track yet. I went but broke my driveshaft on the first pass so I didn't get a result from it. But it should get me in the 1.4-1.5 60's and hopefully down into the mid 7's.
