Re: [DML] Questions on Houstons engine

[Marc Levy <malevy_nj@xxxxxxxxx>]

When this engine first came out, I asked the same
question.

The response I got was that the heads were milled to
increase compression (I imagine this is minimal due to
the timing chain length).  Most of the performance
gain came from the free-flow exhaust and hot cams. 
IMHO, the free flow exhaust probably accounts for at
least half of the performance gain.

You can do a lot with the PRV to get more power out of
it.  However, I think 190 is about the max you could
do without MAJOR engine modification or forced
induction. I investigated a number of options, but
found them to all be very expensive.

How do you figure it is double?  I thought it went
from 130 to 190? That is like 65% increase, right?

After considering the DMCH engine as well as other
options to increase performance, I opted to TRY and do
my own conversion.  My feeling was that engine
technology had been improved so much in the past 25
years that it was silly to spend money on the PRV...
Of course, at the rate I am going there will be a new
and better engine by the time I am done!  :)
