Dyno'd my PTE 54 trim

[90AWDTalon]

VRMAN, what kind of dyno was it?

I just got mine done today on a mustang dyno. The results were very weird, I put down less power than expected, but thats not a big deal because I heard that was normal on those dyno's. But what was really weird was the car acted totally different on the dyno than in the real world on the street. On the street in 3rd gear I hit 20psi by 2800-2900 rpm with super fast spool up. On the dyno I was starting to build boost as soon as he went wot at 1500 rpm, the spool wasn't much there though, it really started taking off at 2200 rpm's but I wasn't hitting full boost until about 3300 rpm. Also it just didn't seem to accelerate like it does on the street. Any ways I'm going to compile all the data I got, take a picture of the print out and start my own thread alittle later.

thats because dynos dont load your car the way the street does. thats why its better to tune it on the street and then go dyno it. ive heard that people have lost motors due to lean conditions from being tuned on the dyno.

Do you mean they lost the motor on the dyno, or they lost the motor on the street because they leaned it out too much while on the dyno?

the latter.

Retardation and Loading
• Single retarder (PAU) per axle (std.)
• Auxiliary 2nd retarder option rear axle*
• Eddy current retardation (PAU)
• High load available at low speed
• Electronic load cell force measuring system
• Electromagnetic roller exit brake

From what i can tell its the closest you can get to a rear world road. Its kinda werid hitting the gas and the cars rpms not moving at all b/c of the load on the car.

90AWD: It was a dynojet, whatever that tells you.

Okay, so with the mods in my profile I plan to add:

Zeitronix wideband
ImportPower propane injection kit (98 octane on pump gas)
Taboospeedshop Billet steel shift fork
Street Radials for the track

At that point, I am just going to focus on tuning and hope to push the setup to the max. I am still holding out hope for 116mph traps on 110 octane and 25psi. The intercooler shouldn't heatsoak right away and the higher octane will supress knock. Seems the consenus is 110 or so but similar setups in my area on running 115+ so with some good tuning I think I can hit that.

Street Radials for the track

! I think you mean 'drag radials'....
We all have street radials......

When are you taking it to the track?

99gstracer:

I'm hoping to get it up to the track in October. I will have the car ready to go running:

110 octane gas
Nitto drag radials
Tuned for running 26psi high boost
Fresh passenger axle
LSD insert
Koni Yellow shocks up front

Got a guess for me? I'm going to have a goal of 13.4 @ 114
