A liitle to wide , perhaps lose 10 - 15 cms , but as you say the thing with the rocket is its all big . Would pay a lot ( more than $400 ) for the right thing that takes my fancy , but would have to look really good , and racy type thing .
Perhaps if the core was more dense & thicker front to back
it could be smaller,but would need good airflow.
I beleive WadeyJ is working on one for his
turbo jobbie.
