phunk's Whipple GT

[phunk]

If you have put them on and then get a tune. It will be 800+ if you want. I would stop at 700ish.

Sorry for my ninja edit... ya my goal is about 725rwhp. I figure I will need to step down the pulley a hair, and with the LTH and E85 it shouldnt be too much to ask.

The car on dyno. There was more fans behind the blower focused on the heat exchanger

Whipple looks great on that engine bay Phunk...

 

[Badcompany]

That things awesome!!!!

I spoke to Whipple and they confirmed that their new house tune will resolve this, and that I can get it immediately.

So - it obviously makes the most sense for now to go ahead and get their latest tune!!!!

It looks like it might not even be a week before I have an updated dyno graph to share!

Are they gonna do the calibration for the headers too?

 

[phunk]

I mention the headers in the mods list, so I would figure they do, if there is anything they really even need to change for that. I have never personally tuned a car before/after with just headers being the only difference to know how much adjustment really needs to be made.

A huge difference. Tuning will need to change a lot.

I would be curious as to the reality of it. I wont say that it doesnt need to change, but I will say that at this point I dont imagine it being a very drastic difference and possibly negligible.

A portion of the power they create is by reducing pumping losses on the exhaust stroke, which seems somewhat unrelated to the tune in a way... perhaps freeing some load could allow the motor to accept more timing, although that wouldnt be saying that it needs it, just that it could take it.

Boost could go down if the cylinders fill more through improved exhaust gas clearing... but if airflow truly increases, the MAF should see this and adjust accordingly so long as the tables are already tuned this far.

I dont tune all day every day, I just tinker with it on some cars depending on what EMS. I would like to hear a solid explanation on what needs to change in the tune for the headers. Perhaps some cam timing adjustments could be of benefit on vehicles that allow it?

^^ Either way, I would not let it go un-monitored and I will always make sure the car is safe after any changes are made.

Wow, how did I miss your thread phunk? Lol

Very glad you took my advice and talked to Dustin. He really is a great guy and truly cares about his customers. I also am getting this new tune and hope to be up and running mid next week. I am getting 654 rwhp on my car but this is at only 7000 rpm

Any other power mods on your car at the moment? Probably not worth comparing our numbers while throttles or rev limits are cutting out, but next week we can!

Attached is a photo of how I changed the fuel feed line. Obviously the stuff that comes with the kit works fine and great, but I wanted this done, looking towards my future fuel system project, and figured a better flowing inlet assembly wouldn't hurt anything for now.

There is a billet QD adapter on the hardpipe to -8 AN with smooth radius 90 -8AN fittings into a 8/6/6 Y block splitting to the rails. The -6 lines have swivel fittings in them, this way I can remove that -8 hose, and I can rotate the Y block down 180 degrees to connect it to my larger feed line that I will put in. This was important to me so that I can build the fuel system without having to remove the blower to get at the rear passenger rail fitting... that was my main justification for doing this during initial installation.

Heads up for anyone who plays with the fuel lines with the setup, you just need to be careful of the hex size of the fitting you put on the back of the passenger rail. If it sticks up any higher than the rail, it will touch the blower (preventing it from seating to intake manifold properly). You want a fitting that matches the hex size of the included whipple fittings (.75"), or you can do what I did since i have inventory, test fit a handful of -6 fittings until you find one that is clocked parallel on top when torqued. Or last resort, file it flat after torquing lol.

Just a Ford Racing Sport Catback. Mine hit 7000 vs your 6200 rpm though

I just got a new tune in from Whipple.

While I was pretty much happy with the original tune, minus the closing throttle after 6700 or whatever... this new one has remedied the negligible gripes I could have otherwise had.

Hot start is clean now, no more minor stuttering while getting it going.

Accel / Decel fuel trim has been mellowed out, no more slight pop or jerk when just nudging the throttle from 0-2%.

Stay tuned!
