FP 1500 Spitfire Carburetor Rule Clarification
#31331 from Steve Sargis · Not recommended · Minutes (2021-12 Fastrack)
Thank you for your letter. Most spec lines that include an alternate side draft carb are also allowed an IR manifold in order to fit
this carb. The Spitfire does not have an allowance for an alternate side draft carb, so the allowance for an IR manifold is not
given. This car is also considered to be competitive as it is currently classed, with its currently allowed carburation.
