400whp on pump w/o aux fueling

Dynojet cf, i've found it to be closer to my actual numbers when I got dyno'd on my k04. But yeah, just switched over to a load tune recently. Only reason i'm even able to get these numbers is because of this "cold" weather we have been having here in FL currently. Now to get that AFR in check because of it. And get on an actual dyno and see where i'm really at.

Attached log, and both dj/cf=1.01 VD graphs. e25 mix.

I"m gonna grab a dyno Saturday and see where mine stands on pump. I really want to equal or break the 400whp no-aux pump gas really bad.
[doublepost=1455161009][/doublepost]@Gandalf are you also running 3.5?

Don't set yourself up for disapointment. 375 is nothing to be unhappy about. Unless ou have a real happy dyno you are on, you shouldn't reach 400. Either that or your IDCs are in the danger zone

Maybe I missed it, what turbo are you running?

I'm running an HTA3586. and my IDC's are pretty bonkers.

That turbo for sure is capable of well north of 400. I'm suprized by what VD is showing, but it tends to be close.

How are you getting traction in 3rd gear? I will also say 4th gear logs tend to be more accurate due to the closer to 1:1 ratio.

You are for sure flowing enough air up top to make 400, but you are close to maxing out your intake. I'm suprized also that you aren't seeing any KR, you muse have really good gas where you are.

I'm just an amature at this. Maybe have a pro like @rfinkle2 look at it and get his thoughts
 
I think the highest I've ever seen was 380whp on a 3076. Dyno verified where we use to go for the ENM.

I run drag radials right now. 245/45r17 Nitto 555r. I'm wanting to move to M&H racemasters after these. Right now I'm having a hard time tuning the car after 7000rpms. I think it's doing whatever it wants. I'll prolly move to Versatune.


@CWP_MS3 you recall who that was? I'd like to see a log of his.
 
Why are you against aux fueling of some sort? Throw on a 5th/6th port and you can climb up north of 500 no problem. Whole set up should be like $1000 or so and make your goal easy
 
I'm not against it. I have meth and pi in the works. I had meth installed but I unhooked it to change the position of the nozzles and I need my pipe modded to fit because of the tb plate. I just haven't done that yet. It was already modded to fit after installing the jmf, and this time it's gonna need cutting and welding. I was just rolling with it on pump without aux for the time being.
 
Here's a vdyno from last winter...temps were in the 20s...this is on a 5858, cpe mani, 3.5" intake, frankenstein front mount (tr8 core basically), on 93...

I can tell you why this phenomenon rarely exists... Because of a complicated combination of airflow, octane injector capacity, whether or not an engine is running forged rods, and the rpm @ which the tq needed to = 400 hp.

Not too many people who are running forged internals are running a pump gas tune, and a smaller group of those same people build an engine without aux fuel.

e.g. someone with a forged engine could make 400 wtq @ 5500 rpm... (or someone with big balls on a stock block)... It would most likely happen @ high tq around that area of the rev band due to the increased demand on the injectors in terms of time available to spray vs redline.

Ryan, your smoothing of 6 is representative of a large tq bump and is inflating your overall auc.

Thanks for your input. Do you also happen to have a chart that accounts for up to 7500rpm?
