Engines

Is it me, or does SHR seem to have terribly bad luck with engines? I really feel like SHR has a disproportionately high number of engine failures... It might also just seem that way because they're a bigger team, but you usually don't see 2 of the Hendrick Motorsports team cars blowing up in a race... or is it just me missing something?

Re: Engines

I felt that way for a little while last night, however, I had to end up writing it off to "that's just racin'" after seeing some of the tires coming apart and remembering what happened at Texas...

Re: Engines

Hendricks engines have had many blown engines so discounting that as just racing-- its NOT. Others have had engine issues also due to mech failure so that is NOT considered just racing either as its bad parts going BAD--period. You can bet Hendricks as well as others are concerned, esp when the Chase rolls around & a blown engine takes their driver OUT of the Chase. :roll:

Someone pointed out some time ago that it also included the CC's who have gone for speed.

Re: Engines

I was listening on the scanner during her pit stop right before the engine blew and her crew chief told her to take it easy on the throttle/shifter as they wanted the engine to last as long as possible.
So they already knew something was going wrong with it.

Re: Engines

I wish I could remember the source of what I am about to
post here, unfortunately it is not popping into my orb.

What I remember of the system, goes something like this.
HMS engine dept gets done with a group of engines.
Dyno sheets are handed out to the assorted buyers/users.
They pick the engines on a rotating system.
ie. Chad picks, Zip picks, and on and on, until all available
engines are spoken for. How the lot is drawn, I don't know.
Does the order change for each batch of engines? Dunno.

What I do think I know with certainty is.... it is the ONLY
way an engine supplier (with his own team) can do it.....
because NOBODY would want their cast offs......

Saw this comment meant as a joke so have to comment jokingly as well that it wouldn't surprise me once the "JR Chase" is underway. :lol: :lol: :lol:

Joking aside--Hendricks has had lots of engines fail as well as other teams, but once the Chase starts a blown engine can likely take a driver OUT of the Chase & that's not a joke & it could even be JR. :roll:

Re: Engines

this isn't new for SHR. It was happening last year too. Don't think it is the motor but however they are tuning them, that is the problem.

Yeah, I'm thinkun the Schmoop might be closer on this deal.

I DO think those engines should be nearly "Bullet proof" though.
They do have rev limiters, so over revving is unlikely.
The best I can come up with is the tuner is running the mixture
a tad closer to lean than he should be. If they are doing that
the Schmoop has it spot on.

For those that might wonder "why lean".... it used to be
(protecting myself from shrapnel here) that the leaner you
ran the engine (within reason) the more power you generate.

Re: Engines

yeah when running the sprint car, we had what is called a weather station. It read the temp of air, moisture in the air & what not. It told us what size pill we wanted to run for the race. We always discussed running a leaner pill, but we didn't have the money if we pushed it to far, so we usually always went with the safer size. But what is interesting is we would switch pills through out the day. Practice started mid day & the main was at night. So I wonder on races like the 600 where the race starts with one temp & weather & changes through the course of the night how the cup teams sets up their fuel injections? Then again we ran alcohol so it might be completely different for all I know. I am not a gear head so I wouldn't really know. But I am curious how they set it up. So much more than just handling that helps a car become fast when going from day to night then I think a lot of people realize.

Re: Engines

We kinda had a rudimentary method. Moon Equipment
produced a meter called an Air Density Meter. It combined
the temperature, the humidity, and the Altitude into one
reading. We based our pill selection from that, with a little
help from my ear for "crispness"..... That's as good as we got.
btw... we were also on alcohol.

And, I am all but certain running as lean as you can get away
with is also applicable with gasoline.

So......... Do they have a "dial" on the ECU that the driver
can tweak from his seat...??? Dunno.... I'll ask an informed
friend, and report back.
