Re: [Amc-list] Acceptable EGT's (was: Stroker 304 back from the Dyno)

[Greg Taylor <amundaza@xxxxxxxxx>]

Hi Chris,
I just did a quick search and come up with 1250-1350 being the max for EGTs, with temps over that being too hot.  Now that I see that and am mentally recalling the visual "do not cross this temp line" on the dyno, I must have had a max EGT on cylinder #5 of around 1250, as now think that line was around 1300 on the dyno.  I'll know for sure when I get an email from Brian, with the dyno results data, and can ask him specifically.
 
Brian used to own the dyno and sold it to Chuck, who does all the machining for my buddy Rick Jones, who helped me put the engine together.  Chuck has done work for Rick for years and worked out the dyno use (for me) with Rick.  I basically got the 'good customer' deal.  18 hours of set-up and dyno time would have normally cost a lot more than I paid.
 
As far as the BSFC goes, if I really get 0.39 BSFC on the road, then MPGs should be awesome.  Here's a reference point for BSFC : 4-stroke (high compression, carburetor)      0.60 (idle) 0.42 (peak torque) 0.47 (peak HP).  This comes from http://www.land-and-sea.com/dyno-tech-talk/using_bsfc.htm

Nice writeup Greg, thank you.  I've had an EGT installed (#5 cylinder 
only) on our Cherokee for about 6 months now and haven't been able to 
find any information on what temps are acceptable and what aren't.  Our 
401 (since defunked) was running 1400-1450* when towing.  And so far our 
360 hasn't seen over 1200* (Haven't towed with it either and it's
been cool outside).  Do you know someone with the dyno or did you have to 
rent a whole day's worth of shop time???  I look forward to seeing what 
kind of mileage you get with that, with all the work that's been done to
it.

Chris
