Re: IML: Blown 392 Megasquirt EFI

Aron and Rob
Thanks for the advice
About the compresion ratio of the pistons,I did order the 8 to 1 blower 
pistons.
But I wil overdrive the blower @ 13 % So I will be making 13 to 15  pounds 
of boost.
With this I hope that I can get close to the 2 HP per CU Inch .
Will install 4 bold mains , ARP head,main and rod bolds, Titanium O ringed 
head gaskets.
When the headers are a big problem with the torsion bars I will wait till 
next year with them.
This winter I do the engine and brakes, next winter I plan on airride the 
year after that I am not sure but maby
some body mods and a mild top schop.
I used the Imp as daily driver for 5 years, now I have bought a other car 
for the wintermonths.
So there is now time to work on the imperial.

Regards
Remco
