At the track with stock turbo...
very good times matt... congrats...
you guys are making cams for the car?
if so are you expecting any power out the the cams it self or just to rev higher with the big turbo set-up? (which obviosly will get you a good amount of power lol)
also what are you guys reving it up to with the valve springs?

they slow you down mainly because you need to run a larger diameter rim....bigger the wheel bigger the rotating mass your trying to make go aread = slowing down. it wont be a HUGE difference but in racing every little thing counts.
i wanna say the minimum you can run on the brembos is a 17 and most need a spacer...shaved lsj brakes.....15's with a nice meaty tire like they run

well its not the brembos themselves that slow you down...its just the fact that you need to run a larger wheel which will slow you down a bit.
The brembos are actually heavier than the lsj brakes. So even if you could fit a 15 over them they still would slow you down over the lsj brakes. It may not be much but it is some. And with a slotted rotor and a sticky brake pad they stop very similar to the brembos.

I see how it was done now.
Do you use the port fuelers above a certain load?
There's finer atomization offered at higher rpms and read that you are using the DI system to do the brunt of the work as it is...almost like a dual shower set up on a F1 car, or close to how the dual injector setups run on bikes.

confused.
So you're running the stock airbox with the zzp mod, plus you have an intake? Does that not mean you have no stock airbox anymore?

It's very interesting you are running the DI injectors and getting that power at 2800 psi, I guess I stopped too soon. I ran out of fuel at 2700 psi in the midrange and popped a limp mode on low fuel rail pressure and gave up the 100% E85.
Must be time to try it again.
How are you doing with hard starting cold? Mine was being a b!tch on E85, any clues?
Congrats!

My injector ms went to about 12 ms and it started breaking up a bit with a .90 PE lambda, When it got to 6500 in third and I let off it popped a CEL & limp mode for low fuel rail pressure. That was on E85 running 24 psi boost and 23* advance with the stock tranny ratio. My actual lambda showed .93 from the wideband during that pull. I was running the Trifecta base file with 2700 psi pressure >160% load.
I figured I couldn't get enough fuel into the DI window and backed off to 50% ethanol after that.
Here's a link to the post on HPTuners... I'm flowing ~31 lb/min VE when this happened.
