Once again........ I missed it! Not really even close.

SAE HP 376.03 / TQ 457.13 (Street performance program)

Last try:

SAE HP 377.98 / TQ 464.95 (Street performance program)

I replaced the Borla with the JDM Silver Bullet. That probably didn't affect performance much one way or the other. I added the Accufab throttle body, Water-Wetter, and the AFM power-pipe. I didn't expect to see 25 hp from these mods; but, I did expect an improvement, not a loss. The air/fuel for this trip was only slightly richer; so, there are a few extra horses left in the fuel trim. It looks like the electric fan and Cobra R water pump are next in line. The rest of the mods are in my sig.

 

Don't feel like The Lone Ranger !

Looking at your sig saying 2# upper and 2# lower.I do not have an aftermarket upper but from what I hear it is not a true 2#.More like 1 ,maybe 1 1/2.Do you have an aftermarket boost guage?
Personally I would consider a 4# lower.
The electric fan is also an excellent idea.very L should have that anyway.

Don't worry you will get there.
One more question. How long was the cool down before the first pull?

 

More like Tonto.......... Kee-moe-sah-bee.

 

I've heard 1-2 lbs of boost from the interchangeable upper pulley. The lower is questionable for a full 2 lbs., also. The original JDM lower is slightly smaller than the other vendors 2 lb. pulleys. I may go ahead and switch to a larger lower by next spring or summer.

My cool down before the first run was 20 min. Each run today had at least 15 min. between them. 5 runs total.

 

Believe it or not with only 20 minutes of cool down your motor was probaly hotter then when you shut it off.The heat has no wear to go and builds up before it cools down.That may not be the best explanation,but think about it.
For your most optimal numbers you are looking at one to two hours cool down.The blower should be cool (or at least not warm) to the touch.
Again this is for THE MOST OPTIMAL NUMBER.
Also since the first pull will PROBALY gain you the best results,use the aggressive program first then work your way down.(the hotter the blower gets the lower the numbers)
I have dynoed about 6 times now (18 pulls all together) and this is stuff I have learned.
Hope it helps.

VINNIE,

18 pulls for me, too. I always have an AM appointment and do my cool down sitting before the fans. I start the motor at 10 minutes and let it run for a few then let it sit for another 10 before the fans. The blower is cool to the touch by the time I make the first run. If the place I use is going to be busy on the the day I am scheduling for, I try a different day. I usually get about 3.5 to 4 hours on the drum. No rush. I don't want a totally cool engine for the first run. I want repeatability throughout my dyno session. If the motor gets too cool, I let it run til I reach operating temp again.

I want to see how much power I have at all times, not at the most optimal times. It's a daily driver and I'm not competing with anyone to get the best numbers I can, just want to find out where I stand when I'm sitting at a light after driving for the past half-hour. The 400/500 club is secondary to having a safe tune; but, I sure would like to get there some day.

 

Could not agree more.No sense in having 400 H.P. sitting on the side of the road waiting for a tow truck.
You will definately get there one day.
I am dynoing next week to see what it took to get this beast into the 11s.I am hoping for 425/550,but who knows.

VINNIE

 

I'm a little leary of putting a larger pulley on right now. I don't want to waste the money when I am considering upgrading the blower alltogether.

 

TP

 

I made 386/457 with no pullys or electric fan. Just a good tune. Those are SAE #s. All I have is Swanson chip, Accufab throttle body and Swanson air filter. Ithink you need to spend some time on a better program.

 

what have you done to get you into the 11's??that arent allready listed in your sig.

nice job i hope to be there in the spring

 

8# pulley and everything else EXCEPT Built motor,Built tranny and front skinnies.
Yes, I ran an 11.93 with those HEAVY A$$ 20 inch replicas.
4800 lb. at the scales.

I am going to try one more time this year with skinnies up front if the weather agrees.Hoping for 11.79.

VINNIE

 

Odin's Wrath,

Your numbers seem low to me. I pulled 381/477 SAE with just chip, filter, 2lb lower, line mod valve, 4x4 trans pan. Check your fuel filter and plugs. Thanks again for the Power Pipe help.

BTJ

P.S. Don't get caught up in dyno numbers. A lot of variances involved. 99svtlightning dynoed his old 99 and pulled a 387/48x and yet ran 12.07 at 112 MPH. I have seen a lot of dyno monsters never deliver at the strip. Keep the faith bro.

BTJ

 

BTJ,

Plugs look good and I just changed the fuel filter about 100 miles ago. It runs strong and the power couldn't be smoother. Beautiful dyno sheets.

BTW Your welcome I hope it 's working out for you with the power-pipe.

In all honesty, I think the Dynojet this guy uses is screwed. He has a whole wall of vehicles that don't make the power they should. A stock ZO6 making 330 rwhp? It's still frustrating.
