I see this in some notes on model year differences for 1st gens:

"When engine decelerating, all air/fuel diverted to front rotor to prevent backfire."

Can someone detail on how to remove this feature?

This is a pure race car this is for, not street.

Im also open on opinions concerning jetting changes for racing.

Im the leader of the Pro7 class I race with currently, but..more help cant hurt.

 

That feature is on the manifold and isint on an 83 AFAIK. Oh and welcome to the board.

 

Cool..thanks for the welcome!

This last weekend was also my 35th bday, and it was a double-win weekend too.



Of course..now I have some noisy wheel bearings to find (as usual).

 

IIRC, 83s have small front bearings. Do yourself a favor and get a pair of 84-85 struts. Less bearing problems.

 

I'll think about that...once I burn thru my large pile of junkyard rotors all packed and ready to race.

Probly be next year before that happens.

The spindles last about 3-4 weekends before they go 'limp-dick' at the end and REALLY tear things up fast (pads, bearings, tires..)
