Damn those are good numbers. Does it pull hard?

nice numbers, im wondering what you wouldve got with S4's, cause i seen a few charts of people breakin 160's with s4's with i/h/e/p and upgraded ecu

Rob, looking at that chart, it looks like you Max HP is around 6900rpm. If my research is correct, if you advance any more intake timing it will go lower. For every 1 degree advanced in the intake the power band drops about 100rpm. I think the power band is where it needs to be. Try +3, -1 anyways, if the power band drop to 6800-6900rpm what I read is true and I would suggest +1, 0.

Also, your running a AEM CAI right? I don't know if this is true or not either but they said that the 2.5" tube from the filter to the maf is restrictive for any cams, 3" intake pipe will yield higher HP.

I could be wrong, but after seeing the dyno I think it can be 190hp. making me want to run N/A, hahaha

I herd from him that he was pulling on a LT1 Z28

Sorry to ask but did you play with basics such as the TPS setting, cleaning Air Filter, putting new spark plugs?

I've seen it work somewhat different for some setups... TPS 0.50V and some other times 0.45V works better and gives you some more ponnies/torque!

Depending on your JWT ECU program, timing should be dead set on either 15 or 25 degrees.

You may have done all this, but just trying to help, once you got these at best setting then moving cam gears is next...

My setup liked best +5 -5 with JWT S5 + Flat Pistons on SSAC 2.5 + 2.5 Exhaust, maybe you can do +3 -3?


I don't this he's going to do anything like that until he gets the Calum

what? the dyno "graph" stopped at 7k not the dyno itself. since he ran it til 8k and it shows his max HP at around 6900, IMO I wouldn't adjust the intake more.

I think you have it backwards, most would say +2 intake, -2 exhaust, and go from there.

I was pulling on my friends 91 z28 with the 350, but I'm fairly confident that this car is now a high 13 car judging from the dyno numbers I've put down, and I still have some power to squeeze out (hopefuly this week )

The JWT ECU should be able to handle cam gear changes. I am going to try either +3 -1 or +4 -2 this week. I will be getting a wideband O2 and a safc once I find one for sale at a decent price, and then I can fine tune everything.

try the cam gear setting before the dyno and see what feels best. take note of the 2 settings that feel best then dyno thoes 2.

thats what I'm doing. I'm setting the gears at +3 -1 tomorrow.

I read his response wrong and thought that the rpm scale was wrong on the chart. :o

Do you think this set-up would run mid-range to low 13's with slicks?
