Whipple Power Compilation

[Apollo]

Damn... 925:eek Holy Cow...:banana Is 104 Sonoco leaded? I can get unleaded Unocol 101 around my house so if I ended up with the high 800's, I'd more than happy as I still would like to keep the OEM cats on the car.

Are the Gen III 4.0 Whipples still CA CARB approved?

They were when I bought mine and I don't think that would change.:thumbsup

 

[427Aggie]

I've got a barrel of 105 Unleaded sitting there waiting for me to tune for it....Thats the highest I can find in Unleaded.

You would half to ask Dustin or Dennis at Whipple if the 4.0 is CA Carb approved.
And yes Sonoco makes 104 unleaded. I heard that someone makes 110 unleaded I am waiting to find out. I have a cat back pipe, converters and stock exhaust manifolds and am running the o2 sensors. Headers are not alway's the answer, you would be surprised what a flow bench and machine work can do for stock exhaust? :eek

744rwhp gen 2 91 pump

 

[peiserg]

Can you tell a noob what the difference is between Gen 1 and 2? is gen 2 full aftermarket, but same manufacturer? Searching around yields a lot of discussion on people installing the whipple.. but not much on the stock blower.

925 RWHP on the 4.0 Whipple. This is on 104 Sonoco race fuel. There are also 16 other changes, some more significant than others. My car spent 3 months on the dyno to achieve these results last winter. There was some trial and error plus brain dammage. But we never went inside the motor. Go back months and look at all of the Whipple 4.0 threads. There is a lot of information. It is amazing this day in age that a car can be a daily driver, achieve this horse power and get mid 20's on fuel for highway driving. I have SMOKED everything I have raced on the road. I Love my GT!

that is awesome! what kind of headers and exhuast are you running?

VP's MS110 is the highest unleaded race gas you can get. the research octane is 110 and the motor octane is 101 for a M+R/2 of 105.5 octane. i use it in my viper when i spray a 150 shot.

Believe it or not, stock exhaust manifolds, stock converters, o2 sensors and a cat back pipe. Headers are not allway's the answer. It is amazing what you can accomplish to the exhaust system with some machine work and a flow bench. :eek

Perfect solution for those in tough emission law states.

VP's MS110 is the highest unleaded race gas you can get.

Despite that it is 110 Octane, it goes by the product designation "MS109". Go figure.

The 110 or 109 is an optimistic number. Using pump octane rating of (RON+MON)/2 the octane number would be much lower.

 

[nota4re]

The point of the post was not to dispute the Octane level or rating but to clarify the product name is "MS109".... and Fast Freddy already gave the pump comparison of 105.5.

[Waldo]

4.0 liter Whipple, 19 pounds of boost, 93 octane tune, 737 rwhp and 668 lbft of torque.

 

[John B]

Gen I 709 rwhp, 19 psi, Ida exhaust, plugs & conservative tune. No probs in 3 years.

 

[911teo]

4.0 liter Whipple, 19 pounds of boost, 93 octane tune, 737 rwhp and 668 lbft or torque.

Exactly the same!

4.0 Liter Whipple, 19 pulley, 93 equivalent (euro fuel), 738 whp at 6,770 rpm and 667.7 lbft at 5,568 rpm (550 at 2k rpm, 600 at 2,500 rpm)

But I always take dyno numbers with a pinch of salt.... especially different dynos in different countries etc....

 

[Waldo]

Exactly the same!

It's because they're both Silver GTs.

The 3.3 and 4.0 are 50-state emissions legal.

Friday night, we dyno'd a GT with the 4.0L, Accufab TB, JBA headers with cats, x-pipe and with 104 octane, it made 862rwhp (6300) before we ran out of fuel pump. Installing the MSD pump boosters soon and should be no problem making 900rwhp. This is with a stock air box, K&N filter. Later, will be replacing air system as there's another 50-75hp stuck in that box and MAF.

Wow, the biggest numbers I have heard of, other than Rockstar's or those cars with engine mods!

I didn't know an alternative to a Boost-a-pump existed. What do you like more about the MSD compared to the KB? Do you need to use 2 of these boxes?

Wow. That is awesome!

1. What size pulley?
2. What was the PSI boost?
3. Stock Fuel Injectors?
