First trike build engineering questions...

[DELTA V]

Transferred post from newby section per Zammy's suggestion.

Design layout more or less set so far:

Tandem seating, rear drive.

3.8L GM FWD Automatic drivetrain (220HP) putting the track in the 60 inch hub to hub range.

Wheelbase in the 132 inch range due to the seating. 24-26 inch rolling diameter tires.

Center of gravity somewhere near passenger rear seat bottom.

So now the questions:

1. Is there an issue with overturn angle with these specs?

2. Having almost unlimited choice of Rake, Trail, and fork length at this phase, how to determine the best geometry for these?

3. What kind of steering stop angles are needed lock to lock to be able to have decent turning radius?

That will keep me busy for a while! Thanks.

Will work on some better drawings as it progresses.

looks fast.....there is a lot of info on rake and trail on these forums. having built a rear engine set up similar to what you have drawn....add some ducting and good cooling fans, early on, for radiator cooling. Having full floorboards on my trike i had some concern about getting light on the front end @ higher speeds, not been a problem....some thing to consider with your body design. Larry

Hi Larry, Checked out your build and it looks great! You have been there and done that.

Lots of things that were in my head that I can actually see is good motivation.

Bonneville background? Going for a trike speed record? COOL!!!
