Something like this?

Exactly!

...aaaaand now I'm looking for Vette superchargers again. Thanks. My wallet's lucky you don't make C4 E-Force units.

I noticed once when sitting and logging with the car ON but engine not started that when I slammed the accelerator pedal down the actual throttle plate would move about 1/2 a second later (you can hear it move). I thought it was kind of interesting as a direct cable driven system would be immediate and figured a fly by wire system would be the same, I guess not! I wonder how much this contributes to the feeling of "lag".


I agree with swithclanez it's nothing to lose sleep over, but it's certainly not as smooth as any OEM power delivery I've ever felt. Also good to note that at high RPM shifts there is no lag whatsoever, at least for me...

Most cars have less than a 0.15s delay... thats not normal. I've been in enough CARB Edelbrock cars to know that's not normal for the E-force either.

Not disagreeing with you there, I love the response of my old cable cars, but that said, this is newer tech still being perfected, and they are getting damn close to cable response without the issues of a mechanical system like breaking/throttle hanging open. Plus DBW gives you more tuning flexibility like throttle curve maps, auto rev-matching, flat foot upshifting, and launch control. I enjoy the car more because of these thing, and that's what happy motoring is all about in my opinion. Your mileage may vary.

Over the past couple of days, i've paid more attention to my throttle to see if there's any hesitation. I have an auto, so it doesn't stall or depend on throttle/clutch skills, so maybe it doesn't apply in this case. throttle response is definitely slower than my last car (which was cable), but i can't really see a difference between stock and post SC install. i'd have to compare it to another stock auto. power delivery seems pretty smooth, and i only notice the slightest hesitation when it's cold and hasn't warmed up yet. it's gone in the first half mile. above 2500 rpm, throttle response is quick enough for me - no complaints.

my previous car (280Z) was was primitive by today's standards; and not the easiest to drive in traffic. the throttle was actually a bit too responsive for stop and go traffic, and combined with the heavy clutch, most people i let drive the car would keep stalling it, LOL. here's what i had on my Z:

Just for gits n shiggles, I took a log of what you were asking for since I felt that I would notice a very slight hesitation/tip-in throttle every once in a while.

Note: I could have sworn I selected map to be kpa, but I guess I have it set to bars...

full throttle, 2.5k-4k rpm - http://datazap.me/u/bigfatflip/16021...log=0&data=6-8

partial throttle, 2.5k-4k rpm - http://datazap.me/u/bigfatflip/16021...log=0&data=6-8

I think what I'm noticing is more the throttle mapping. I noticed a huge difference in feel between going partial to higher (but not 100%) throttle position and going from partial to 100% (foot on floor). There was definitely almost no "lag" or hesitation going to 100%, just a good steady build-up.

Also, could this be at all related to how the by-pass valve behaves? ie the split second it takes for it to fully close?

do you recommend waiting for E-Force releasing stage 2 or this kit could be use for 400bhp just by upgrading 70mm pulley and 900cc injector and DW300 fuel pump?

IMO, I would be worried about issues with engine longevity at those power levels given the PD blower's torque curve. Assuming a built engine, I would be confident in running this kit with a smaller pulley and flex fuel, given the feedback from Delicious' results with a similar setup.

I do not stress the car and i do not go track.
superchargers make less boost at higher altitude , my city altitude is 1200m above sea level and 400bhp power convert to 340bhp in my city.

I do not worry about that power (12psi) with E85.
i just worry about throttle response after supercharging because i guess i reduce sharp throttle in lower rpm

Lots of info on this on the forums but the basics are as follows:

7 psi will usually run as long as you'll own the car...about 1% that are safely tuned at that power level will fail for one stupid reason or another. Still exceeding OEM torque by 75%.

12 psi will run a good while, about 10% of those will fail after 30-50k miles.

15 psi (400+ WHP) will fail. Guaranteed, just a question of when. Some go a couple years, others go a few months.

Now nearly universally some knowitall will raise their hand and say they've gone 10 years and 100k miles at 500 whp on the stock motor--it's all in the tune. No, its not. It is more often just all highway miles and likely a very optimistic dyno, or possibly a creative imagination. Steel and aluminum fatigue. At stock power levels they will not fatigue until your bearings are well worn and the car is as the scrap yard. But when getting pounded with double the stress, expect 1/4 the life.

For those worried about the FA20 in the BRZ have some solace--subaru felt it was good enough as is to use in the FA20DIT at near 300 hp with some very minor changes. I disagree with Subaru that that was a good idea (we've taken apart a few) but if you don't beat on it too bad and use good fuel you should have no problems.

Anyone have and can post any recent dyno charts with their Edelbrock SC build on e85? For comparison.

Not sure if this was answered but on their site it says emission pending. So is this not legal yet? Or does this meaning something else?

I will later this week.
Having the charger installed Tuesday. And We will be running e85.
