He said a Whipple would have good top-end power with alcohol injection, and you said a Whipple does have good top-end with methanol.
You say tomato, he says tomahto.

 

Before Whipple = 262/308

After Whipple/A2W intercooler = 422/517.......all #'s are rear wheel on a Mustang Dyno.

I have not had it on the Dyno since i put the 60's and Corsa exhaust on though, so I am hoping for more. It weighs 7000+lbs and runs mid to low 13's in the 1/4.

Not bad for a Whipple IMHO. I also think something else was going on with your rig there TEX to only see a 10/75 gain.

 

Anything without a intercooler is leaving alot on the table. Some type of cooling is needed.

 

Whippled 496, you're telling us how good your truck runs intercooled, and you can't understand why BigTex only made as much as he did non-intercooled.
I seem to remember you complaining about how your's ran pre-intercooler.

 

Awwww c'mon Mike. Even pre intercooler i was doing better than 10/75 over stock. You bolt on a $2000+ power adder and i am going to expect a little better than 10/75. I would like to see at least 12/78 .

Im not a Whipple spokes person by any means.....just saying with the right combo of parts its not to bad of a thing.

 

That's my point. I am not sure that I was doing any better than that with the Whippletronics or even after they were removed. It felt quite a bit torquier, and I was never sure that it had much more top-end than stock. I never had it dyno'd, did you have yours dyno'd pre-intercooler?

 

Yeah i did. I dont know where i put the graph, but after the intercooler, timing turned up a few degrees , and 1/8" smaller pulley.....it made another 50hp/60tq at the rear wheel +/- a little bit. I have not dyno'ed it since the 60lb'ers and Corsa though.

 

Yea, I am not very inpressed with mine right now. Did not make as much notice as I expected for it saying it makes 7.5 lbs. It is leaking oil from down inside the pulley shaft. I just pulled the pulley shaft off and there is a small pin hole from the inside of the case on the shaft to inside the shaft where the nut goes down inside to hold it on. Is this vent hole suppose to be here? Mine has the dip stick built on the fill plug (old style i guess). Do I check the oil by just setting the dip stick in or do I thread it all the way down?

 

Yea man, I saw your truck up there, nice set up, that is who did mine. I love the tune and driveability but something just isnt there with the whip.

 

I wanted to have plenty of room for more power later so I went with 42lb but my stock ones were 28 or 29lb
