We can expect a written response to the questions I sent to Deist, however,
I'll summarize a phone call I received from them this afternoon:
SFI specs are taken from NHRA. We'll get directions to their website that has
full details.
Deist hasn't sought approval from any other sanctioning groups, but they sell
lots of patterns for racers that aren't just going 1/4 miles. As a safety
device, they don't see why it wouldn't be allowed.
The SFI rating is good for 2 years (!) Same as blower hold-downs (anybody got
those?)
The outer layer is oil resistant and can be wiped clean. Cleaning agents are
not recommended.
The blanket is multi-layer (Kevlar inside). Should weigh about 4 lbs with our
pattern.
It is designed to cover only the bell housing, so "it shouldn't trap too much
heat" in the trans.
A wrap-around is the only way to go to keep parts from ricocheting off the
pavement and re-entering the car.
More to come from Deist directly.....

Sirs,
Since I initially contacted you about ordering a transmission blanket for a
vintage TR4 racer, several fellow TR racers have expressed interest in this
safety device. This could lead to a multi-unit order to you, however, several
questions have been raised about transmission blankets that I forward to you
to answer. If you send your reply to "fot@autox.team.net" all interested
members will receive it.
1) Your blanket is SFI approved. Can you give us an idea of what the approval
spec is? i.e. design and test requirements, etc. (Just the basics!)
2) Has this device been reviewed by vintage sports car racing sanctioning
groups? Reasons why it would/would not be allowed?
3) For road racing use, does a transmission blanket create heat build-up? Do
you recommend that cooling devices be added?
4) Besides SFI specs, is there an approach using Kevlar blanket that doesn't
entirely wrap the transmission? Could the blanket of Kevlar be bolted inside
a transmission tunnel, for example? Our primary concern is driver protection.
Thanks for your prompt reply.
