Hey guys Just got my car Dyno tuned last weekend, my setup is basically a stockport motor with a t78, the car was only tuned for 14.5 pounds ( due to the wastegate spring) and i ended up making 347whp and 301 wtq on a mustang dyno. I had an opprotunity to get tuned by a very good tuner from new jersey, and i am pleased with the results, also does anybody have an idea of about how much power it would have read on a dynojet? i read somewhere that the difference is about 12%, but i'm not too sure. Car was tuned by Abraham Alba, here's the video:

Car sounded really good. Healthy motor done by eccentric performance. And the tune was crisp. Abraham did an amazing job on it.

Mustangs read about 10% lower than a Dynojet. Your numbers seem a little low but as long as the car runs well I wouldn't worry about it.

looks like a professional shop.

NOT!

all things aside, that is not a safe way to run a dyno. Especially where that fat *** guy with the rusky hat is standing. One minor problem with the tie-down and his fat *** will shrink real quick when the car flattens him against the lift post. IMO there shouldnt be anyone within 15ft of a dyno run except the person pressing on the gas pedal.

Those numbers are low even for that dyno. My old T78 was at about 400 around that psi. I was street ported though.

i figured the tuner told me he kept it pretty conservative, but the car feels great on the road so i'm happy with it for now, they're just numbers, it could really read anything depending on how it's set up. so i'm not too worried about it.

i say 400whp on a dynojet . i hate those mustang dynos lol pretty sure that turbo works alot better on higher boost then that

drftinmx6

iTrader: (6)

yeah i agree

Likewise with Jason.... Im not too much of an expert with Mustang dynos but for reference i made 430 @ 12 lbs on a DynoDynamics with correction..

Is it just me or does any one else hear the breakup on the top end? Suprised not reflected on the dyno grap.
350@ 1 bar does seem low for that turbo, but stock ports are limiting

iTrader: (6)

i don't hear any breakup?

i make around 60-70whp less on a mustang dyno. but its just a number. i actually like tuning on them since everyone thinks you have a slow car then next thing you know you have a bus length on them lol.

People.like you is why this world is.so lame!!! Go nag somewhere else you square.

LOL yeah man right after the tune i raced a turbocharged 2005 mustang GT that was running about 6 lbs of boost, and i put bus lengths on him, lol i ran into him a couple of days ago and he was complimenting me on how fast my car was.

hahaha if i could like this comment like it was on facebook I would!

I thought the same thing! @ 9-10seconds it sounds like it breaks up but it might be distorted sound as well.

drftinmx6

iTrader: (6)

Yeah I believe it's distorted sound now that I listen to it again, the video was recorded from a phone

Yes its literally a blip,, then 2-300 more rpm then blip blip blip, then he gets out of it, would have like to see him pull it to 7,500

drftinmx6

iTrader: (6)

yeah well me and islander were there in person and the car sounded clean with every pull he did, believe me if it was breaking up the tuner would have told me and we definately would have not have been questioning it. Only reason he stopped the tune where it was at was because of the wastegate spring and he could not turn up the boost anymore.

I can bare witness to the 'pullage' his tune consists of. That dyno must have read very very low. Tune held up well on the Dragon.

...Thanks B, the M3 is scared to come out of the garage now

Hahaha, this statement is so true. I love telling people I have a low horsepower number then skull drag them when it comes down to race. As long as the car runs well and the power band is there, I'm happy...I got over chasing horsepower numbers a while ago.

Mustang dyno's are known as heart breakers, now you know why ahhaa. Just use a dyno for tuning purposes, they all show different numbers like stated above. As long as the tune is correct, you're good to go!

OOH.. this thread has gotten me all excited!

I've got a T78 I need to get up and running. Problem is I am a little low on funding at the moment and still need to get a PFC and intercooler. I was thinking of running a cheaper M-spec, or god-speed FMIC with it so I can get the project moving faster. anybody with t-78's been successful with cheaper inter cooler options?

I see it as the item I may be able to save a little money on and spend towards engine management and gauges instead.

any input?

an intercooler is an intercooler, all that really matters is the dimensions of it, and if it's doing it's job, if you're going to go cheap on an intercooler then use the rest of the money on a good EMS and either run the car on E85 or invest in a good water-injection/meth kit. hell i have a greddy knock off intercooler on my car and it does its job just fine.
