Hot Rod Cams + Whipple/Summer Fun Part 2
well fed-ex dropped off the sprocket
bolts and cam cover gaskets on saturday, so
i was left with no reason to delay the install.
i followed the sticky, step by step and everything
went well. loaded up my newly revised tune and
she fired right up.
my thought after driving the car around for over
an hour, is he nailed it. the way the rpms come
down while coasting to a stop is improved and dare
i say it, possibly perfect.
i know this much... if this had been the way the car
idled the first time around, the cams would not have
come out.
side note: highway mpg, flat road, 60mph = 22 / 65mph = 21
once again here is the disclaimer, to head off the negative
comments about lopey cams + FI.
should everybody with FI run out and install thumpers
or hot rods? absolutely not. but for those of you who
want (and need) the lope, go for it. just make sure you
have a dyno tuner at your disposal, to work with you
to create a tune that you are satisfied with.
summary: i'm very happy with the way the car is running
and idling now.

hey there shanec, well mainly the tune is what
changed this time.
since pulling the cams last november, my tuner
has tuned a few stangs with thumpers and
he learned alot in the process.
i wouldn't have put the cams back in, but he
felt he knew now, how to settle the
idle down while coasting and it looks like
he was right.

hey thanks war machine. i believe the
dyno printout from last fall, showed 10.48 psi,
which is what i used to see on my boost gauge
with the stock cams.
i haven't gone wot yet, but in the next few weeks,
i'll see what she's able to put out.
if there is any torque loss at all at low rpms, it's
minimal and not anything worth noting.

i don't think so. i'm pretty sure the tuner just
made some adjustments that affect low rpm idle.
the custom dyno tune from last fall resulted in
467rwhp / 458 tq @ 10.48psi. my stock whipple
tune made roughly 420/420.
i'm not saying the cams were the reason for the
power increase, more so it was the custom
tune.
