Subject: [Fot] Undetuning and restoration of a TR250
Over the past couple of months, I have finally gotten started on the
restoration of my TR250. I have had this car since it was new. It is very
nearly in original condition, because I never had the money to modify it
back when I wanted to. Since I plan to keep it fairly original, the FoT is
probably the wrong group to be talking to. So, where do the 6 cylinder guys
hang out?
'68 was the first year the emission laws started to take their toll on
performance, as evidenced by the TR5 vs TR250. I would like to make it
perform better, while keeping a stock looking engine appearance. I'm
thinking along the lines of the 125 mph car that Kas did for publicity back
in the day. My thoughts at this point are to increase the compression to
the limits imposed by pump gas. Change to a longer duration cam, i.e. more
like the early PI cam. I'm not sure how to tune the nonadjustable carbs
when the engine is modified. I was also thinking about getting rid of the
wacky ignition retard, but continuing to use the vacuum advance. Does
anyone have any suggestions on how I can accomplish my goal within the
limits I've imposed?
I have an old Cam Doctor that I have used to look at several TR3/4 cams. I
have a fairly popular webpage on those cams at www.TildenTechnologies.com.
.As part of this effort, I'd like to do some research and a similar page for
6 cylinder cams. Does anyone have an early PI cam that I could borrow to
analyze for this effort? Or, perhaps other street performance cams?
Thanks,
Larry Young
