Whipple 2.9 or 3.4?

Hey guys, as no one has helped me in the past more than you all I thought it prudent to present the question posted here. My goals are to have a complete animal as my non-DD but be able to cruise comfortably when I am not romping the throttle. Is a 3.4 liter whipple too much for daily driving or will it be fine if I drive around regularly with the exception of a couple WOT runs whenever I take it out? I don't want to be limited by the 2.9 (if that could be the case) but understand that it is probably a more suitable blower for your weekend cruise. Please give me your opinions as well as what all I will need other than the blower (ie injector size/spark plugs/ TB/Elbow etc), you know...the costs that aren't originally budgeted. THanks soo much for any of your knowledge/experience!!

Have a friend that drives his Shelby all the time with a 3.4 Whipple and its perfectly fine for a daily driver. He swaps pulleys/tunes when he knows hes going out to have fun with friends. Pretty sure if you get the 3.4 you'll need an aftermarket hood though

Re: Whipple 2.9 or 3.4?

with the 3.4 you will have to lower the motor or use a big hood scoop or a aftermarket hood but it will support about any hp you can handle . I don't care for the 2.9 . 428cj

Re: Whipple 2.9 or 3.4?

If you are interested in hearing about the Kenne Bell 2.8 I'd be happy to discuss it with you. Great Throttle response and nothing beats a Kenne Bell Supercharger whine.

Never hurts to talk and look at all the options.

Re: Whipple 2.9 or 3.4?

Thanks a LOT guys! I think that it looks like a 3.4 is the way to go unless I explore other vendors as Van recommends. BTW Van: LOVE the HE.....never would have thought I could eliminate that heat soak feeling. The reason I am intrigued by the Whipples is the price....the 2.8 KB is probably much more than I can get a 3.4 Whipple for.

Thanks for the PM. Let's do a cost analysis. You might be surprised how well the KB can accommodate your needs.
