De-bugged the tune and got better numbers

[fangs99]

Well I had a bad O2 that needed to be changed and the tune was way rich and had a lean spike at throttle tip in. So I got Brad at XXX to adjust the tune.... It drives like a dream now... Instead of the turbo feeling like an on/off switch at 4,000 rpm and old dog lazy out of boost, this motor feels strong then the transision into boost is 100% smoother. Before I would see 1-2 lbs of boost at 3,600-3,800 rpm now I see 1-2 psi at 2,800rpm and the candle really lights off at about 3,500 now.

My new numbers now are 635 rwhp 606 rwtq SAE.

Congrats dude.

 

[sdsubzero4]

Nice numbers!

 

[fangs99]

Just wondering how many 600+ rwhp cars are in the club (on pump gas).

 

[seahawksax]

I wish! One day I hope

2005 Tahoe LT ( family truck)
1993 camaro Z28 super charged (sold)
2000 mustang GT supercharged (sold)
2006 mustang GT with a $9,800 build list ( taking donations )

Didn't Yose get over 600 after nitrous? Then Emilio is close or a little over also.

 

[fangs99]

Yose, made 570 on spray.

 

[fangs99]

Ok... So maybe 2 of us out of the whole club.... There's got to be more... Sounds like a new thread topic... I'm sure boostedmach has a 700+hp street monster he's not telling us about.

 

[Ford1288]

Oh yeah, forgot about him. I can't think of anyone else, used to have a GT in NC that was doing a sick turbo build but he hasn't been on the site in awhile. Next one to get it will probably be the GT500 up in Washington.

 

[sdsubzero4]

One of these days I will be there.

Your going to need more than that little KB to make 600 rwhp on pump.

Scott's (fangs99) Dyno sheet and video

 

[Ford1288]

What size turbo again? Surprised it flattened off at 6k.

Oh, I know that. Plan is to build the motor, forge and stroke out. But that is way down in the future when the $$ is better. Turn up the boost and see where it goes.

 

[V.I. Massive]

there is a GT in Bremerton Chapter that makes 800 hp on pump I believe. Tuned out of the Mustang Ranch/ TMS.

 

[V.I. Massive]

I have a video some where of its dyno during a dyno day.

 

[fangs99]

My turbo is a Precision 76mm. The power flaten out at 6K because of the non-ported stock runner intake... If I went with a shorter runner intake, power would keep climbing.

 

[Ford1288]

Interesting. How much boost?

 

[fangs99]

13 lbs of boost and 12 degrees of timing

 

[fangs99]

This combo isn't trying... Next is a meth kit & 16 lbs of boost should be about 750 rwhp then.
