Why do you guys keep talking about car motors??

This is a boat forum.

Car motors and boat motors requirements are nowhere near the same.

I love turbo's also... and am pretty sure they are the future.

But lets get real... the fastest car motors...top fuel dragsters...dont use turbo's. These guys have unobtanium budgets and could use any power adder the wanted...and they choose to use roots style blowers...there must be a reason.

Wow...now here I go...talking about car motors in a boat forum...what a retard I am sometimes!

Lets keep this about boat motors...OK?
This is a boat forum...right?

Chris

P.S. Awsome job Dustin!...I love it that you keep pushing the envelope

Great Thread:

A lot of great questions and answers from Whipplecharged.

I also agree the thread title could have focused more on the Whipple product. The results of the engine performance speaks for itself why bring in any mention of turbos.

I had some follow up questions:

1. What is the cost of this engine as it sits? If that is not something you want to discuss how about the cost of the Whipple 4.0l quad w/MOAC complete kit.

2. Have you tried any other types of heads with this set-up?

3. If you have 4.0 litres X 2= 8.0 litres versus a 8.3 litre single unit it seems on the surface that a single unit is still pushing more volume? Can you elaborate on this issue.

4. A lot of questions on longevity (hours) on the service life of this engine have not been answered (err maybe I missed it) can you give us an estiimate. Also what are the tuning challenges if any on this motor?

5. The belts at high RPM on the 8.3 in the ribbed version were not surviving. I run a 8mm belt versus a ribbed belt and run up to 6400RPM and never had an issue. I know of some boaters wherein this was or still is a problem. Is this a solution or rationale for going to a quad rotor set-up. Can you explain?

Thanks for the follow up on a lot of great questions asked and answered most of which have been on point for most of us.

KAP

P.S. I went from a 3.3/205 to a 8.3 and I have been extremely happy with the 8.3 it runs like a swiss watch perfect every time. The 8.3 is so hard to beat IMO.... so I am having a hard time justifying the return to a quad rotor not to mention the cost benefit analysis.

On screw blowers, one would traditionally measure the output of the blower while spinning the smaller rotor. The whipple 5.0l is rated when spinning the small rotor. If you spin the big rotor on the 5.0l, it is then 8.3l per rev. In essence, they are pretty much the same blower.
