Whipple first impressions

I got my car back from Heffner Friday and drove it to work on Saturday but today was the first real chance I had to give it a shakedown run. 732 HP and 664 torque. I took the beast out today with the wife to put some miles on it and get reacquainted with the traction limits. I had gathered from some of you that already had the Whipple that a much lighter right foot was required now. You were right.

At average driving speeds and RPMs there's really no difference in the stock car and the Whippleized one. Very controllable and smooth, idles nicely, sounds about the same, and throttle feel hasn't changed. But once the RPMs start building, say 4000 plus, you start to realize what an extra 200 horses can do for you (or TO you if you're not careful). It seems to gain RPMs quicker and makes a much more FEROCIOUS noise through the Accufab X-pipe. The car stays very solidly planted but you can feel what almost seems like chassis flex as you shift gears and nail it again. My wife thinks the tires were breaking loose at each shift but in the higher gears it felt more like the engine was torqueing sideways. Maybe some of you more experienced racer types can comment on this. All I know is that this baby never quits pulling hard until it hits redline. I thought the stock car pulled hard but this one is amazing. I showed my wife what 150 felt like REAL quick.

On the low end of things, tread lightly. Never nail this thing in a turn until you're straightened out and then be ready to control the tail end cause it's gonna break loose. Once you know this, you can have a lot of fun getting a little drift out of any corner you want to. Wifey started getting mad of course so I'll have to practice that later.

As luck would have it, I just happened to line up at a red light with a V-Rod who wanted to play and had the first good street race I've felt comfortable with. No traffic and wide open road, just perfect conditions. From a rolling 30 MPH start I just blew him away. He and I were both impressed.

Overall, I haven't found any drawbacks and am very happy with the results. I can break the tires loose at will but everyday driveability is still great. The jewel factor is just a bonus.

My advice...skip the pulley and go straight to the Whipple. Don't try to convince anybody that the pulley is more "bang for the buck" or the Whipple is "too much money" either. If you can afford this car, you can afford this upgrade.

The only reason to pass on this upgrade is if you're going to blast right past it and go twin turbo!!:cheers

Fantastic! I bet it felt like a new animal after the new SC was put on. Congrats on the new power!:cheers

I can't wait to get a whipple as well...but it'll be for the L (cause I don't have my FGT yet:wink)

whats the lowest speed or gear it will get traction in if you go WOT?

Im considering the Whipple but after having a 800+rwhp Z06, I no longer want a dyno queen. It was really frustrating not having traction below 100mph.

oh and I forgot to say congratulions

You will not have traction below 100 mph if you stab the throttle in either 1st or 2nd gear. Pedal modulation, allows it to become manageable.

With the increased hp the gearing actually feel much different. Stock, it seemed like the car was in 1st gear forever. With the power levels we're taking about, you better be ready to shift right now.

You will suprise more then a few litre bikes and pull on 600's with your new found power. Enjoy the car and make some videos.

Sorry to be argumentative, but I have the package to be tractable. Have you driven a GT with a Whipple? I find it perfectly manageable, but then again, have been driving high horsepower vehicles all my adult life.

don't overlook the tip about not stepping on gas until your car and steering wheel are both pointing straight ahead. Could be the longest 3 seconds you ever spend.

Congrats on the upgrade.

Thanks for your comments and observations.

While I have found violent horsepower to be a welcome benefit from the Whipple, I find the power delivery to also be very linear; the Whipple creates more usable power at all levels. One of the most obvious differences I noticed driving a stock GT and mine back-to-back is that the Whipple responds to even the slightest nudge of the throttle, even at lower revs.

It's like the whole GT experience is just that much more amazing -- like hearing your favorite song on the stereo, and then listening to it live; same song, different experience. :wink

Nice write-up. I'll have to drive one myself to compare having been in all the pulley, KB HCD kit, and TT setups.

I just have the 2.7 pulley and it is wicked. I would kill myself with more power. Just the pulley's added boost and I can absolutely smoke my tires at 80mph. That's nuts.

Congrats on your new rocketship.

Dead on... cool tire = bad traction and cool air = more power. That's a bad combo. I was lucky that nobody was around when I found that out. It was a very scary 3 seconds.
