New DynoJet runs: 572 rwhp!!

[632C2]

One of the benefits of having a DynoJet is being able to test at will. Since I am new to this supercharging thing I am still learning. The best way I know to learn is by making more runs and trying different things.

As I stated in my last thread, I have had a few conversations with Tony at HP Performance and he has been excellent to deal with. He never makes a guy feel like a dummy and is very willing to share information. And although I have only talked to him on the phone, it sounds like he has a smile on his face at all times. I don't know about the rest of you, but he is the kind of guy I like to deal with.

I got his latest tune for the GT and after a few tweaks this is the difference between my runs with the old tune and his tune:

I made two runs with the old tune. RUNFIL~1.DRF represents the first one. I made a total of 4 runs with HP Performance tunes. The first started out at 564 rwhp followed by 569, 569, and 572. RUNFIL~6.DRF represents the sixth one. I am using the datalog feature of the SCT tuner and recording every run. I was in communication with Tony (on a weekend no less!) and he aided me with the adjustments to the tune.

Tony's tune is also a safe one. As you can see, the A/F curve is right in the 12.0:1 range. I am from the old school and read plugs after every run. With Tony's tune, the blueing line is right on the 90* bend of the ground strap - just where it should be.

When I was all through I also performed a compression test and found great results. This motor truly impresses me.

Since I was admonished in my last thread for not using a dyno graph smoothing value of 5, I am basing all the following on that value. As always, these numbers are SAE corrected.

Here is a summary:
_______________rwhp__rwtq
Stock___________511__474
Accufab 'X' pipe__519___483
'X' pipe & tune____534__511
Re-gap plugs_____540__514
HP Perf. Tune_____572__521

Pretty amazing! (As an interesting point, with smoothing set to zero the uncorrected values were 589.43 rwhp and 530.76 rwtq.)

Thanks, Torrie!

I am a little more than half way to your numbers. :ack That is until you make your next set of runs!

[timcantwell]

Great information. Your postings really help to cut through the clutter to define what works and "how". By the way Tony usually does have a smile on his face all the time! :wink

Aye Aye Captain ! You have a free spot in my passenger seat if you ever get over to NEFL.

Thanks Tim! There will be more on the way when I decide what is next.

no what?????????

Bigger turbos, Nitrious Oxide?

[piko6]

just turbos will do HEHEH

 

[FordGTGuy]

just turbos will do HEHEH

hey joe can we upgrade it to this turbo??

 

[632C2]

I am leaning towards a Whipple. I realize that turbocharging is the way to go for really big power but for this car I like the simplicity of the supercharger. Who knows where this will take me.

Joe and Torrie's twin turbo cars appear to be in a league of their own. Being new to this forum, I am not yet familiar with all the different owners here. Does anyone know who is putting out the most power with a GT that has a supercharger?

most power i've seen with the stock blower is 700+ rwhp but I heard the 3.3l blower is good for 900+ rwhp. However I don't know who has the most powerful supercharged Ford GT on this board.

 

[tmcphail]

Steve my suggestion to you would be to allow me to take you out in my car for a ride. It is unlike anything else and needs to be experienced to be understood. Words cannot properly describe it.

I come from a long line of hi HP positive displacement blower cars and trucks and now thanks to Joe I am a total Turbo convert. Every time I pull my car out of the garage it continues to blow my mind. :biggrin :biggrin :biggrin

Torrie,
I believe it is truely mindblowing, but the drivability suffers because the torque kicks in violently at a certain point of revvs, which is why so many F40's ended up in the trees. I guess, not having ever had the pleasure to ride in yours or Joe's TTGT's.
The charger has a good aspect to it, it is continuously pulling from 1500 onwards, no lag, no hit in the back sudden boost, and of course, a different - lower- league.
But I also think maybe the Whipple (what, it get's to like 800 HP easy !?) is probably more streetable. Consider wet, moist cool roads..unlike Florida sunny day driving, of course..

 

[tmcphail]

Drivability does not suffer when the car is calibrated properly. From there its a matter of personal choice. I always had KB cobra's and lightning's so I am entirely familiar with the power band of twin screws. It was what I came to know and love until I went for a ride in Joe's car. Now for me its turbo all the way. Which echo's back to what I was saying prior about the need to experience it before you write it off as being something you dislike.

Torrie,

That is a very generous offer - and much appreciated! I have never been to Florida but you have given me a good reason to go. The video of your car was quite impressive.

Did you do any of the supercharger mods or just go directly to the turbo's? Based on your experience with PD blowers, what kind of power do you estimate a properly tuned Whipple will be able to produce with the stock longblock? I realize that boost is the major factor here and I am not sure how much boost a stock longblock can withstand.

I was initially looking to go whipple months ago and without a product and having good friends that can easily TT my car at hand the decision was easy for me to go that route instead. I will never look back.

I can't speak directly what you can get out of the whipple setup since I have not worked with that blower on a GT and I don't like to guess. I am sure its capable.

I pullied my car on day 2 of ownership with 340 miles on the clock and got 618RWHP out of it.

All of the graphs and the historic timeline on my car is here :

The supercharger upgrade is certainly much, much simpler and much, much cheaper, but the tt has considerable versatility. If the concern is the "violent hp increase" set the boost level to rise at whatever rate you want with the boost controller to smooth out the hp curve or limit it. Later if more hp is desired, simply turn up the boost.

The tt also is easier on the engine, the sc uses at least 75hp(probably much more) to spin the blower at full boost, so at say 700 measured hp your actually asking the engine to make 775.
