wich one? and why?

 

It depends...I'd get the whipple for now but turbo's are putting out some great numbers. The whipple is better for stock internals and don't reqiure as much maintenaince as most turbos...

 

you need to find out those questions. it will be 50/50 like always and you'll still be asking the same question. go searching!

 

i have a friend that has a 412hp twin-turbo 350z and now i have some money so i want to buy either a whipple or a hellion, they are around the same price. in december im going to his house so i want to race him

 

As far as I hve seen, the whipple is the safer bet. Don't get me wrong, if I didn't order my Procharger already and I got a good deal, I would consider a turbo.

 

tubos are great, but they do generate a ton of heat under the hood...i say whipple

Whipple all the way. Just the sound of the whipple at WOT would make it an easy decision to me. Then there's the easy install of the whipple, so easy you could do it yourself. The whipple looks much cleaner under the hood (looks like it belongs), just my opinion though.

The fact that the hellion routes the exhaust pipe under the lower control arms killed it for me. I'm lowered 1.5 inches and there is just too much crap on the roads to hit those pipes. I could pull the whipple off in 12 hours (guestimation) and be back to stock if need be(without spending any money), i don't think anyone can claim that with the hellion.

I've never heard of a whippled engine blowing with the stock tune and 10psi, i can't say that about the hellion.

Whipples customer service via emailis second to none and i'm a brenspeed customer. Not sure about hellion, but try sending an email to both with a question about each kit and see who responds the quickest.

Yeah, i'm happy with my whipple.

 

Yet again you are going to get the responses from people that own the kit that will obviously vote for what they bought.
Best off doing independent research, not some poll on a public forum.
What's important to you....performance? looks? sound?install? etc...
For me it was based on power potential and customer support and I made my decision based off that.
One thing is for certain, and that is that both will transform your ride.
