Lifters tested and work

[dykz34]

HP gains at or under 5hp are REALLY, REALLY hard to prove. Hell, I did back to back dyno runs and there was a 3hp difference EACH RUN. How can anyone prove there is a 5hp gain? Not that it matters, every little bit helps.

That is what a mustang dyno is for. Its much more consistant/accurate than the dynojet.

Doesnt that dyno also yield lower numbers to simulate real world results?

That is to say, if we had a magic tranny with 0% drivetrain loss, would a mustang dyno yield 210 HP on a stock magically flawless DOHC?

[SappySE107]

How would that be yielding lower numbers? A stock 3.1 3 speed beretta had 100 or 101 hp on the mustang dyno. I dunno what a dynojet would say,but the mustang dyno was consistant, within .3 hp.

[Gemmer]

Well Im not so sure about the 3.1s numbers, so Im not sure what that means...

But I was told that the mustang dyno takes away from true HP to give a better idea of real world results.

Trying to figure out how to word what they explained to me.

Ok, for instance, a 210 HP 3.4, considering a magical 0% drivetrain loss, would dyno a 210 give or take say 10 HP because of inaccuracy

Now I have been told that a Mustang dyno out of 210 would yield like 190 (number pulled outa my ass) give or take maybe 1 HP to inaccuracies

That is to say THe mustang dyno, although more accurate run to run, will give you a lower number to simulate actual on street performance. What "on street performance" is I have no idea...wieght and and friction or something I guess...

I have no idea if this is true or not. If not, I guess the people who say it are just using it as an excuse as to why their car gets bad numbers

Personally I could care less about "real world performance", way too many variables for such a simple thing.

[pocket-rocket]

You probably are thinking of weight, friction, and wind resistance most likely. Either way, I don't think that the weight of the car should matter on the dyno, your getting the power to the wheels regardless of the weight. I do remember reading something where someone was messing with a chassis dyno and entered in different weights for the car when it asked for it, and the numbers for hp and tq had changed with each different weight setting.

My old hs has a mustang dyno, and from talking with dave last night, dave from colorado, i now realize why so many high powered cars came out with lower numbers at the wheels.

[LQ1]

has anyone purchased these? I may be interested.

[farmerz24]

these look like gm 2.4 lifters from the 2.4 twincam.

[Dave]

hey LQ1 there's a couple mustang dynos in MN right now, I can't remember the names of them but I'll get back to you later with that info.

[SappySE107]

The 2.4 lifters are 33mm, not 35mm.

[Sorin]

WTF! Take your wares elsewhere!

Oh wait.......you run this place.......nm

[SappySE107]

I help run it, I dont do everything around here
