Default My G5X3 dyno!!!

Link to thread HERE

Air inlet was 109, A/F ??? I dont know, Ran out of gas on the dyno Damn Fuel gauge. Mods are on my sig link to cardomain. newly added is Ported TB, Looks like to me they only pulled it to 6200rpms, can low fuel cause it to loose power (aka Low Fuel Table) or is that a myth? I mean besides running out of Gas

I think thats a myth!

The chart is kinda hard to read, but it looks like it spikes towards the end of the graph giving a false reading of the 401 RWHP. looks like it's pretty smooth down in the 390-395 area though, which is pretty respectable. Seems like it peeks a 6000 RPM, kinda strange...I think there is more in it if you find out why it hits a wall at 6K..

Good luck!
Dan

Those numbers do not look right, and the peak definatley is in the wrong place...who did the cam install? Are you sure it was degreed properly?

Hmmm a shop around here, guy has done tons of LS1 installs, use to be a Head tech at a well known shop, think maybe I have fuel starvation problems??? there is another guy that has almost the same numbers, then it also might be the tune, they didnt have a wide O2, he went off of logs.(i think)

Oh yea, I am still running thru Cats (Carsound 3" cats) do you think that could hold it back, looked like it was running flat after 6200rpms, it wasnt starting to dip from what I can tell, but I am no expert. But she does pull Like a MuthaFuqer

With a 114 LSA that cam should no go flat until 6700 RPM...Maybe fuel starvation is the problem...are you still on the stock pump...I know that the stock injectors can handle it, maybe you just need to upgrade the pump.

Well wouldnt the graph be more spikey if it was running out of fuel, and the tuner would of mention my car running lean do to the fact the pump wouldnt be pumping enough fuel. Also what would cause the little spike at the end of the graph? And what does valve float look like on a graph?
