They both seem a little high.

 

What do you want? Street? Strip? Dyno queen?

 

Street/Strip.

 

having the W2W engine installed later this year.....they are a top notch company with a very reputable history.

Basically depends on which heads and what rods you want. You can have either package altered to get whatever you want. Both are great companies, but Rapid has always seemed a little high on there pricing compared to others.

 

For clarification purposes our crate engines now use the new Dart cylinder head. Our site will be updated.

The parts cost alone is what produces a higher selling price than other offerings. We are very strict on what parts we use and all prospective parts go though a very strict testing process before we decide what to use.

Thank you for the interest.

 

so what do you think is the limit of both N/A on pump gas? and what options to get there?????

Chris.

 

Hey Chris. You getting our twin Rotrex kit yet?

Here is a dyno graph of our carb turn key version running on pump gas. Our standard corrected figures have shown almost 580 hp.

Our 402 N/A version can also handle enough nitrous to make close to 900 at the flywheel.

 

Thanks for you input guys and thank you W2W for responding to this thread.

 

No problem.

If you have any other questions feel free to contact me.
